Median Overall Survival In Group Research Articles

Oncological outcomes and complications following radical cystectomy with or without neoadjuvant chemotherapy - A retrospective comparative cohort study from a single-center in South India.

Neoadjuvant chemotherapy (NAC) in the management of muscle-invasive bladder carcinoma has not been adopted universally. We studied the oncological outcomes and complications in patients who underwent radical cystectomy (RC) with or without NAC. A retrospective review of patients who underwent RC with or without NAC from June 2009 to June 2020 was conducted. Oncological outcomes, overall survival (OS) and recurrence-free survival (RFS), complications, and prognostic factors were analyzed. Of the 314 patients who underwent RC, 83 patients received NAC (Group A), and 231 underwent RC alone (Group B). The median age was 58 years. The median follow-up duration was 22 (3-64) and 24 (3-62) months, respectively. The median OS in Group A was significantly higher than Group B (38 months [confidence interval (CI): 34-42] and 32 [CI: 29-35], respectively, [P = 0.033]). The RFS in Groups A and B was 34 (CI: 30-39) and 31 (CI: 28-34) months, respectively (P = 0.47). Higher pathological T stage (T3/4), node positivity and lymphovascular invasion (LVI) were predictors of poor OS and RFS (P < 0.0001). Clavien grades 3/4 complications were comparable (8% vs. 15%; P = 0.19). Glomerular filtration rate (GFR) <60 mL/min/1.73 m2 was associated with higher postoperative complications in both groups (P = 0.012). The OS with NAC was superior to upfront RC. RFS was, however, comparable. NAC was safe and well-tolerated. Pathologically, higher T stage, node positivity, and LVI were associated with poorer OS and RFS. Low GFR negatively influenced postoperative complications.

First-Line Systemic Treatment for Initially Unresectable Colorectal Liver Metastases

In patients with colorectal cancer and unresectable liver-only metastases (CRLM), treatment with folinic acid, fluorouracil, and oxaliplatin (FOLFOX) plus irinotecan (FOLFOXIRI) and bevacizumab vs FOLFOX/folinic acid, fluorouracil, and irinotecan (FOLFIRI) plus bevacizumab increased progression-free survival, response, and R0/R1 resection/ablation rates, as well as toxic effects in RAS/BRAFV600E-variant and/or right-sided tumors. FOLFOX/FOLFIRI-panitumumab vs FOLFOX/FOLFIRI-bevacizumab increased response at the cost of more toxic effects in RAS/BRAFV600E wild-type, left-sided tumors. To present long-term outcomes of treatment with FOLFOXIRI plus bevacizumab vs FOLFOX/FOLFIRI plus bevacizumab and FOLFOX/FOLFIRI plus panitumumab vs FOLFOX/FOLFIRI + bevacizumab. The randomized phase 3 CAIRO5 trial included patients with initially unresectable CRLM in 46 Dutch centers and 1 Belgian center between November 2014 and January 2022. A liver expert panel repeatedly evaluated resectability. Patients with RAS/BRAFV600E-variant and/or right-sided tumors randomly received FOLFOX/FOLFIRI-bevacizumab (group 1) or FOLFOXIRI-bevacizumab (group 2), and those with RAS/BRAFV600E wild-type, left-sided tumors received FOLFOX/FOLFIRI-bevacizumab (group 3) or FOLFOX/FOLFIRI-panitumumab (group 4). Adjuvant chemotherapy (ACT) after complete local treatment was recommended but not standard. Overall survival (OS) was analyzed as a secondary outcome. Other outcomes were post hoc analyses. A total of 530 patients (327 male [62%] and 203 female individuals [38%]; median age, 62 [IQR, 54-69] years) were randomized: 148 in group 1, 146 in group 2, 118 in group 3, and 118 in group 4. The median OS in group 1 was 23.6 (95% CI, 20.1-27.5) vs 24.1 (95% CI, 21.0-30.9) months in group 2 (hazard ratio [HR], 0.90; 95% CI, 0.70-1.17; P = .44), and 39.9 (95% CI, 30.7-44.6) in group 3 vs 38.3 (95% CI, 35.3-51.3) months in group 4 (HR, 0.95; 95% CI, 0.68-1.32; P = .75). OS was longest after complete local treatment without early (≤6 months) recurrence (64.3 months; 95% CI, 57.6 to not reached) and salvage local treatment options after early recurrence (58.9; 95% CI, 47.3 to not reached), followed by patients without salvage local treatment after early recurrence (30.5; 95% CI, 24.4-33.4) and with incomplete local treatment (28.7; 95% CI, 25.9-38.3), and worst in patients with continued unresectability (18.3; 95% CI, 15.7-20.0). After confounder adjustment, ACT was associated with longer OS (HR, 0.66; 95% CI, 0.44-0.98) and relapse-free survival (HR, 0.65; 95% CI, 0.48-0.88) and less early recurrence without salvage local treatment (odds ratio, 0.46; 95% CI, 0.25-0.85). These results support using FOLFOX/FOLFIRI-bevacizumab for patients with initially unresectable CRLM irrespective of RAS/BRAFV600E status and tumor sidedness. Patients with complete local liver treatment with salvage local treatment in case of early recurrence had the longest OS. ACT might be considered for these patients. ClinicalTrials.gov NCT02162563.

Seasonal influences on the efficacy of anti-programmed cell death (ligand) 1 inhibitors in lung cancer.

Seasonal variations in systemic immunity have been reported. This study aimed to evaluate whether seasonality affects the efficacy of anticancer immunotherapy. A total of 604 patients with lung cancer receiving single anti-programmed cell death (ligand) 1 (anti-PD-[L]1) inhibitors from two prospective observational cohorts were screened. Primary outcomes were progression-free survival (PFS) and overall survival (OS). Patients were classified into two groups according to the season when the treatment started: winter (November-February) and other seasons (March-October). Kaplan-Meier analysis and Cox proportional hazards models were fitted to evaluate the impact of seasonality on survival. For validation, propensity score matching was performed. A total of 484 patients with advanced non-small cell lung cancer were included. In an unmatched population, multivariable analysis demonstrated that the winter group (n=173) had a significantly lower risk of progression or death from immunotherapy than the other group (n=311) (PFS: hazard ratio [HR],0.77 [95% confidence interval (CI), 0.62-0.96]; p=.018; OS: HR,0.77 [95% CI, 0.1-0.98]; p=.032). In a propensity score-matched population, the winter group (n=162) showed significantly longer median PFS (2.8 months [95% CI, 1.9-4.1 months] vs. 2.0 months [95% CI, 1.4-2.7 months]; p=.009) than the other group (n=162). The winter group's median OS was also significantly longer than that of the other group (13.4 months [95% CI, 10.2-18.0 months] vs. 8.0 months [95% CI, 3.6-8.7 months]; p=.012). The trend toward longer survival in the winter group continued in subgroup analyses. Starting an anti-PD-(L)1 inhibitor in winter was associated with better treatment outcomes in patients with lung cancer compared to other seasons.

Impact of maintenance pemetrexed cessation on clinical outcomes of patients with metastatic non-squamous NSCLC.

8568 Background: Combination chemoimmunotherapy including pemetrexed and a PD(L)1 inhibitor is a common first line systemic approach for patients with metastatic non-squamous non-small cell lung cancer (NSCLC). Patients often discontinue maintenance pemetrexed due to adverse effects, and little is known about the impact of maintenance pemetrexed cessation on progression free survival (PFS) and overall survival (OS). Methods: 121 patients with stage IV or recurrent, metastatic non-squamous NSCLC treated at VUMC were included in this retrospective analysis. Patients diagnosed between 7/2017- 9/2023 were included if they received maintenance pemetrexed and pembrolizumab. Patients were divided into two groups: those who stopped pemetrexed due to toxicity and those who did not. PFS and OS were measured from time of stage IV or metastatic diagnosis to the date of radiographic progression or death, respectively, and compared with the Kaplan Meier method. Results: Among patients with stage IV or recurrent, metastatic NSCLC (n = 121), who remained on maintenance pemetrexed and pembrolizumab (n=68), the median PFS was 11.7 months (95% CI, 7.47-NA) compared to 24.3 months (95% CI, 19.4-NA) among patients who stopped maintenance pemetrexed (n=53; p=0.1). The median OS in the same patient groups was 25.8 months (95% CI, 13.8-NA) compared to 36.4 months (95% CI, 26.9-NA) (p=0.15), respectively. Among patients with stage IV disease at diagnosis (n = 97), the median PFS among patients who did not stop pemetrexed was 8.7 months (95% CI, 7.2–NA) compared to 24.3 months (95% CI, 17.3-NA) for patients who stopped pemetrexed (p=0.089). The median OS in these groups were 21 months (95% CI, 13.6-NA) and 38.6 months (95%, 28.0-NA) (p=0.054), respectively. Conclusions: In this study of patients with metastatic non-squamous NSCLC who received maintenance pemetrexed and pembrolizumab, patients who stopped pemetrexed due to toxicity experienced similar outcomes to those who continued with pemetrexed. The necessity of continuation of maintenance chemotherapy should be further evaluated in the immunotherapy era. [Table: see text]

Possibilities of long-term atezolizumab immunotherapy in patients with metastatic urothelial cancer.

e14628 Background: Results from various studies have indicated that atezolizumab can be an effective and well-tolerated treatment option for patients with advanced and metastatic urothelial cancer. However, the landscape of oncological practices in Uzbekistan reflects a scarcity of experience and data concerning the utilization of atezolizumab in the treatment of patients afflicted with urothelial cancer. This research endeavors to bridge this gap by contributing. Methods: In our retrospective study, a total of 44 patients were selected, with a mean age of 64.5±7.6 years, diagnosed with stage IV urothelial cancer and the presence of distant metastases in the lungs, bones, and liver. There were 28 (63.6%) males and 16 (36.4%) females. Group 1 included 18 (40.9%) patients with elevated PD-L1 levels SP142 – IC 2/3, receiving atezolizumab at 1200 mg intravenously (IV) on day 1 of each 21-day cycle + cisplatin at a dose of 70 mg/m2 body surface area (BSA), IV, on day 1 of each cycle, and gemcitabine at a dose of 1000 mg/m2 BSA, IV, on days 1 and 8 of each cycle. Group 2 included 26 (59.1%) patients receiving standard chemotherapy (cisplatin + gemcitabine) in the same regimens. Immunohistochemical analysis was performed using the Ventana Bench Mark Ultra automated stainer with Ventana PD-L1 SP142 monoclonal antibodies. Results: The research was conducted from September 2019 to May 2023, and the administered treatment was the first line for these patients. Treatment was administered until disease progression was registered or until the development of unacceptable toxicity. Grade I toxicity was not observed in both groups. Grade II toxicity in Group 1 was noted in 3 (16.7%), and in Group 2 - in 4 (15.4%). Grade III toxicity was identified in 9 patients (50.0%) in Group 1 and 14 patients (53.8%) in Group 2. Grade IV toxicity was encountered in 6 patients (33.3%) in Group 1 and 8 patients (30.8%) in Group 2. Hematological toxicity, regardless of atezolizumab use, predominated among the III and IV degrees of toxicity. The median overall survival in Group 1 was 14.8 months (95% CI: 12.8-16.2), while in Group 2, it was 11.9 months (95% CI: 9.3-13.5). Progression-free survival in Group 1 was 6.8 months (95% CI: 5.1-7.4), and in Group 2, it was 4.3 months (95% CI: 3.8-5.7). The objective response rate in Group 1 was 44.5%, and in Group 2, it was 38.5%. Conclusions: Atezolizumab, used in combination with standard platinum-based chemotherapy in the first line, improves treatment outcomes for metastatic urothelial cancer by increasing overall survival and progression-free survival without causing an increase in the toxicity of the administered therapy.

Secondary cytoreductive surgery followed by olaparib tablets as maintenance therapy in patients with BRCA mutated recurrent ovarian cancer: A multi-center retrospective study

ObjectiveTo evaluate the effect of secondary cytoreductive surgery (SeCRS) followed by platinum-based chemotherapy (PBC) and olaparib tablets as maintenance therapy in patients with BRCA mutated recurrent epithelial ovarian cancer. MethodsThis was a retrospective study of a prospective database. We collected information on 623 patients diagnosed with BRCA mutated recurrent epithelial ovarian cancer, all of whom underwent SeCRS followed by PBC in combination with or without olaparib. Overall survival and progression-free survival were measured to evaluate treatment effectiveness. ResultsOf the 623 patients recruited, 240 underwent SeCRS plus hyperthermic intraperitoneal chemotherapy followed by PBC and olaparib maintenance therapy (Group A), 248 underwent SeCRS followed by PBC and olaparib maintenance therapy (Group B), and 135 underwent SeCRS followed by PBC only upon recurrence (Group C). The median progression-free survival for Group A was significantly longer than that for Group B (32.5 vs. 24.2 months, P<0.001), and Group B was significantly longer than Group C (24.2 vs. 15.1 months, P<0.001). The median overall survival for Groups A was significantly longer than that for Group B (71.4 vs. 63.5 months, P<0.001), and Group B was significantly longer than Group C (63.5 vs. 47.5 months, P<0.001). ConclusionsThis study suggested that SeCRS followed by PBC and olaparib maintenance therapy resulted in longer overall survival and progression-free survival than SeCRS followed by PBC only in patients with BRCA mutated recurrent ovarian cancer, especially in patients treated with SeCRS plus hyperthermic intraperitoneal chemotherapy.

IMMEDIATE AND LONG-TERM OUTCOMES OF COMPREHENSIVE TREATMENT FOR PATIENTS WITH OVARIAN CANCER STAGE III-IV

Summary. Aim:to evaluate the immediate treatment outcomes and overall and relapse-free survival of patients with ovarian cancer stage III-IV depending on the treatment method. Object and methods: the study presents the overall and relapse-free survival results of 269 patients with ovarian cancer stage III-IV who received comprehensive treatment at the “Prykarpattia Clinical Oncology Center of the Ivano-Frankivsk Regional Council” between 2017 and 2023. Patients were divided into 3 groups based on the treatment method: Group I – primary cytoreductive surgery followed by 6 adjuvant cycles of polychemotherapy (PCT); Group II – three neoadjuvant cycles of PCT, interval cytoreductive surgery, and adjuvant PCT; Group III – 6 cycles of PCT. All patients received chemotherapy following the paclitaxel-carboplatin regimen. Results: in all groups, 19 (7%) cases of platinum-resistant ovarian cancer were identified, and the treatment outcomes for these patients were not included in survival calculations. The 3-year overall cumulative survival rate was 50% in group I, 58% in group II, and 36% in group III. The median overall survival in group I was 31 months, in group II – 37 months, and in group III – 17 months. The 3-year relapse-free cumulative survival was 24% in group I, 48% in group II, and 36% in group III. The median relapse-free survival in group I was 19 months, in group II – 25 months, and in group III – 17 months. Conclusions: relapse-free and overall survival rates were significantly better in patients who received comprehensive treatment compared to those who only underwent chemotherapy cycles. The use of neoadjuvant chemotherapy in patients with stage III-IV ovarian cancer improves relapse-free survival but does not affect overall survival compared to patients who underwent primary cytoreductive surgery.

A long-term retrospective cohort-based risk-benefit analysis of augmenting total cumulative I-131 activity to 37GBq in differentiated thyroid cancer patients with skeletal metastases

Objective Skeletal metastases in differentiated thyroid cancer (DTC) patients are associated with poor prognosis. The objective was to determine the maximum I-131 cumulative activity that could be safely administered without compromising efficacy. The secondary objective was to identify other prognostic factors affecting survival outcomes. Materials and methods This was a retrospective cohort study done at a tertiary-care institution comprising of data from January 1990-June 2020. 489 DTC patients having skeletal metastases with ≥12 months follow-up were included. Ninety-six percent of patients had thyroidectomy followed by radioiodine therapy for skeletal metastases. All patients were on oral suppressive levothyroxine tablets. External beam radiotherapy (EBRT) and oral tyrosine kinase inhibitors were used whenever indicated. The main outcome measures were overall survival (OS), progression-free survival (PFS), and adverse-events. Results There were 347 (71%) females and 324 (66%) had follicular carcinoma thyroid. Median follow-up was 78 (interquartile range, IQR: 37–153) months. 333 patients (68%) received ≤37GBq I-131 cumulative activity (group 1) and 156 patients (32%) received &gt;37GBq cumulative RAI activity (group 2). Overall median OS and PFS were 74 (95% confidence interval (CI): 62.2–85.8) and 48 (95%CI: 40.5–55.4) months, respectively. The 5-, 10-, 15- and 20-year estimated overall survival probabilities were 55.7%, 28.4%, 14% and 8.3%, respectively. On multivariate analysis, age(&lt;55years) (p&lt;0.001), female gender(p = 0.01), cumulative I-131 activity &gt;37GBq (p&lt;0.001) and EBRT(p = 0.001) were favourably associated with OS; no factors were significantly associated with PFS. The median OS for groups 1 &amp; 2 were 51 versus 90 months (p&lt;0.001) &amp; median PFS for groups 1 &amp; 2 were 45 versus 53 months respectively (p = 0.9). However, cumulative activity &gt;37GBq resulted in more adverse events (2.4%), particularly bone marrow suppression (3.5%). Conclusion For better survival outcomes, cumulative I-131 activity upto 37GBq could be administered with acceptable toxicity to DTC patients with skeletal metastases.

Primary tumor resection improves survival benefit of stage IVB cervical carcinoma: a new perspective.

Recent studies have revealed that primary tumor resection (PTR) surgery could improve prognosis in some solid tumors. Thus, we aimed to investigate whether patients with stage IVB cervical carcinoma can benefit from PTR surgery and who can benefit. We extracted and obtained data on patients with stage IVB cervical carcinoma from the SEER database from 2010 to 2017 and classified them into two groups: the surgery and the non-surgery group. The overall survival (OS) and cancer-specific survival (CSS) of the two groups were compared before and after propensity score matching (PSM). The independent prognostic variables were identified using univariate and multivariate Cox regression analyses. Then, the model was established to select the optimal patients to receive PTR surgery using multivariate logistic regression. After PSM, the study included 476 cervical carcinoma (stage IVB) patients, of whom 238 underwent PTR surgery. Compared to the non-surgery group, the surgery group's median OS and median CSS were both longer (median OS: 27months vs. 13months, P < 0.001; median CSS: 52months vs. 21months, P < 0.001). The model showed no organ metastasis, adenocarcinoma, G1/2, and chemotherapy were more supportive of performing PTR surgery. The calibration curves and DCA showed that the model had high predictive accuracy and excellent clinical applicability. Finally, the "surgery benefit" group had the OS that was approximately four times better than "surgery non-benefit" group. PTR surgery can potentially improve the prognosis of patients with cervical carcinoma at stage IVB. The model could probably select optimal candidates and provide a new perspective on individualized treatment.

A retrospective analysis of secondary cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy in patients with recurrent ovarian cancer.

To evaluate the effect of secondary cytoreductive surgery (SeCRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) in recurrent epithelial ovarian cancer patients. This retrospective study analyzed a prospective database. We collected information of 389 patients who were diagnosed with recurrent epithelial ovarian cancer. All patients underwent SeCRS with or without HIPEC. Overall survival and progression-free survival (PFS) were used to evaluate the treatment effectiveness. Of the 389 patients collected, 123 underwent primary or interval cytoreductive surgery at initial treatment and SeCRS at recurrence (Group A), 130 underwent primary or interval cytoreductive surgery at initial and SeCRS plus HIPEC at recurrence (Group B), and 136 underwent primary or interval cytoreductive surgery plus HIPEC at initial and SeCRS plus HIPEC at recurrence (Group C). The median overall survival for Groups A, B, and C were 49.1 months (95% confidence interval [CI]: 47.6-50.5), 56.0 months (95% CI: 54.2-57.7), and 64.4 months (95% CI: 63.1-65.6), respectively. The median PFS for Groups A, B, and C were 13.1 months (95% CI: 12.6-13.5), 15.0 months (95% CI: 14.2-15.7), and 16.8 months (95% CI: 16.1-17.4), respectively. There were no significant difference in incidence and grade of adverse events among groups. This study suggested that SeCRS plus HIPEC followed by chemotherapy resulted in longer overall survival and PFS than only SeCRS followed by chemotherapy in patients with recurrent ovarian cancer, especially in patients who were treated with repeat HIPEC.

Naples prognostic score may predict overall survival in metastatic pancreatic cancer.

Naples prognostic score (NPS) based on nutritional and inflammatory parameters can predict response to chemotherapy and overall survival (OS) in many cancer types. However, its significance in metastatic pancreatic cancer (PC) remains unclear. We evaluated the prognostic significance of the NPS in patients with metastatic PC receiving first line chemotherapy. We retrospectively analyzed 215 patients with metastatic PC receiving first line FOLFIRINOX chemotherapy. NPS's were calculated using pre-chemotherapy laboratory data. Patients were divided into three groups according to their scores (NPS: 0; 1 & 2; 3 & 4 were grouped as 1, 2 and 3, respectively). The association of NPS with clinicopathological features and OS were evaluated. Median age was 64 years, and median OS was 10.5 months. Hemoglobin levels were lower and Ca-19-9 values were higher with increasing NPS. Frequency of patients with bone and/or liver metastases, and with greater than 5 metastatic focus were higher in group 3. A lower NPS was associated with longer OS. The median OS in groups 1, 2, and 3 were 19.5, 12, and 8 months, respectively, and differed significantly. Univariate analysis revealed effect of NPS (3-4) on OS (HR: 2.38, 1.77-3.19). Other prognostic factors affecting OS were age, ECOG, liver, bone or lymph node metastases, number of metastatic foci (<5 vs >5), de-novo metastatic disease, and serum Ca-19-9 levels. NPS (3-4) was identified as an independent prognostic factor negatively affecting OS (HR: 1.89, 1.34-2.65) in multivariate analysis. NPS may be a useful prognostic marker for the prediction of OS in metastatic PC patients receiving systemic chemotherapy.

Lung Cancer Resection after Immunochemotherapy Versus Chemotherapy in Oligometastatic Nonsmall Cell Lung Cancer.

Neoadjuvant immunochemotherapy is currently being tested in pivotal trials for stage I to III nonsmall cell lung cancer (NSCLC). The impact of immunochemotherapy in patients with oligometastatic disease (OMD) remains undefined. This study aimed to compare the outcomes of radical treatment after the neoadjuvant course of immunochemotherapy versus chemotherapy. We retrospectively analyzed patients with OMD who were treated with immunochemotherapy or chemotherapy combined with local ablation of metastases and radical primary tumor resection between 2017 and 2021. Group A included eight patients with immunochemotherapy; Group B included seven patients with chemotherapy. Descriptive statistical analysis included the characteristics of the patients, tumors, and outcomes. There was no difference in postoperative morbidity rates between the groups (p = 0.626). The 30-day mortality in both groups was 0%. The median overall survival for Group A was not reached, with a median follow-up time of 25 (range: 13-35) months; the median overall survival for Group B was 26 (range: 5-53) months. In Group A, all patients remained alive; in contrast, in Group B, four patients died (p = 0.026). There was no local thoracic recurrence in either group. In Group B, the recurrent disease was identified significantly more often (12.5 vs. 85.75%; p = 0.009). The rates of complete and major pathologic response were 37.5 and 0% in Group A and 42.85 and 14.25% in Group B, respectively. Despite the small patient number and short-term results, the progression-free and overall survival in patients with OMD after local therapy for metastases and primary tumor resection following a neoadjuvant course of immunochemotherapy might be promising compared with chemotherapy.

OPTIMISING THE TREATMENT OF PATIENTS WITH ADVANCED OVARIAN CANCER: AN ANALYSIS OF PRELIMINARY RESULTS

Summary. Aim: to evaluate surgical complications, side effects of chemotherapy, 1- and 3-year survival in patients with advanced ovarian cancer against the background of the introduction of optimized personalized treatment. Object and methods: for this purpose, a comparative analysis of the results of clinical examination and treatment of 74 patients with primary serous ovarian adenocarcinoma of stages III–IV (FIGO 2015) who were treated at the University Clinic of Odesa National Medical University was conducted. Patients were divided into 2 groups: Group IA — patients with primary ovarian cancer who were treated with primary cytoreductive surgery (PDS) + adjuvant chemotherapy (ACT) — 43 patients; IB group — patients with primary ovarian cancer who were treated with neoadjuvant chemotherapy (NACT) + interval cytoreductive surgery (ICS) + adjuvant chemotherapy — 16 patients. Results: the absence of statistical difference in the median overall survival in groups IA (PDS + ACT) and IB (NACT + ICS + ACT) was shown to be explained by the complete volume of cytoreduction performed. There was a change in 3-year survival from 56.3 to 70.7% (χ2 = 0.951; p = 0.329) and an increase in 5-year survival from 12.5 to 60.9% (φ = 0.0012; p &lt; 0.05). In group IB, the percentage of postoperative complications in patients and the average length of hospital stay after cytoreductive surgery were lower than in group IA, but the difference was statistically insignificant. When comparing the frequency of side effects of paclitaxel/carboplatin chemotherapy treatment in groups IA and IB, the values of χ2 = 36.441; p = 0.0195 were obtained. Thus, it was proved that in the IB group, the toxic effects of chemotherapy of 3–4 degrees of severity were significantly more common. Conclusions: there was no statistical difference when comparing the median overall survival and progression-free survival in the study groups. It has also been shown that primary cytoreductive surgery with macroscopically visible residual masses, especially in suboptimal and suboptimal volume (CC 2-3), leads to a significant decrease in survival rates in patients with ovarian cancer.

TIPS plus sequential systemic therapy of advanced HCC patients with tumour thrombus-related symptomatic portal hypertension

ObjectivesPortal vein tumour thrombus (PVTT)–related symptomatic portal hypertension (SPH) leads to a poor prognosis in hepatocellular carcinoma (HCC) patients. A transjugular intrahepatic portosystemic shunt (TIPS) can effectively relieve SPH but its effect remains unclear in PVTT-related SPH. This study aimed to evaluate the clinical value of the TIPS procedure combined with sequential systemic therapy in advanced HCC patients with PVTT-related SPH.MethodsAfter 1:1 propensity score matching (PSM), this retrospective study analysed 42 patients who underwent TIPS placement plus sequential systemic therapy (group A) and 42 patients who received only symptomatic and supportive treatment (group B). The evaluated outcomes were overall survival (OS) and SPH control rate. Cox proportional hazards regression analysis was used to compare OS in the two groups.ResultsIn group A, the technical success rate of the TIPS procedure was 95.2%, and no severe complications occurred. The rebleeding rates in group A and group B were 5.0% and 73.7%, respectively (p < 0.001), and the ascites control rates were 92.0% and 28.0%, respectively (p < 0.001). The median OS of group A was significantly better than that of group B (9.6 [95% CI: 7.1, 12.0] vs. 4.9 [95% CI: 3.9, 5.8], months, p < 0.001). Multivariable analysis showed that TIPS plus sequential systemic therapy (hazard ratio [HR] = 5.799; 95% CI: 3.177, 10.585; p < 0.001) was an independent prognostic factor related to OS. Additionally, PVTT degree (I+II) (p = 0.008), AFP ≤ 400 ng/ml (p = 0.003), and Child–Pugh class A (p = 0.046) were significant predictors of OS.ConclusionTIPS plus sequential systemic therapy is safe and feasible for treating advanced HCC with tumour thrombus-related SPH.Key Points• Portal vein tumour thrombus (PVTT) is common in advanced hepatocellular carcinoma (HCC) and transforms compensated portal hypertension into symptomatic portal hypertension (SPH).• HCC patients with PVTT-related SPH have a very poor prognosis, and there are no effective treatments recommended by the guidelines.• Therefore, a treatment strategy that utilises a transjugular intrahepatic portosystemic shunt (TIPS) to manage SPH combined with sequential systemic therapy in advanced HCC patients is explored in this study for its feasibility and clinical value. This research can fill the gap in current research data to provide clinically meaningful treatment options.

Prognostic value of thoracic tumor staging and volume parameters in non-small cell lung cancer patients with synchronous solitary bone metastasis.

BackgroundNon-small cell lung cancer (NSCLC) patients with synchronous solitary metastasis are a heterogeneous population. The analysis and evaluation of NSCLC patients with synchronous solitary bone metastases by cTN stage (thoracic tumor staging) and volume parameters have not yet been studied. The purpose of this study is to estimate the prognostic value of cTN stage and volume parameters obtained by fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) in NSCLC patients with synchronous solitary bone metastasis.MethodsA total of 157 NSCLC patients with synchronous solitary bone metastasis were retrospectively analyzed. Patients’ cTN stage, metabolic tumor volume (MTV) parameters, and clinical data were collected. Kaplan-Meier survival analysis and a Cox regression model were performed to determine the association between each factor and overall survival (OS). Finally, time-dependent receiver operating characteristic (TDROC) curve analysis was used to assess the predictive capacity of the independent prognostic factors.ResultsKaplan-Meier survival analysis showed significant differences between subgroups in terms of cTN stage. The median OS of group I was 44 months, and the 5-year survival rate was 39.6%. In the multivariate Cox regression analysis, cTN stage, MTV of the whole body (MTVwb), and MTV of thorax (MTVtho) were significantly associated with patient OS, even after adjusting for other clinical factors. However, MTV of bone (MTVbon) was not found to be an independent prognostic factor. TDROC curve analysis showed that cTN stage, MTVwb, and MTVtho had good predictive capacity for NSCLC patients with synchronous solitary bone metastasis. Compared with cTN stage and MTVtho, MTVwb had obviously better predictive specificity and sensitivity for the 5-year survival rate [5-year area under the curve (AUC) of MTVwb =0.844 vs. cTN stage (P=0.035) vs. MTVtho (P=0.052)]. The best cutoff value of MTVwb was 33.05.ConclusionsThe results of this study confirmed that cTN stage, MTVwb, and MTVtho were independent prognostic factors of NSCLC patients with synchronous solitary bone metastases. These factors can be used for risk stratification of these patients. TDROC curve analysis indicated that cTN stage, MTVtho, and MTVwb had good performance for survival prediction.

Significance of Lymphocyte-to-Monocyte Ratio and Corrected Levels of Serum Calcium as Prognostic Markers in Patients with Newly Diagnosed Multiple Myeloma

To investigate the significance of peripheral blood lymphocyte to monocyte ratio (LMR) and corrected levels of serum calcium (cCa) as prognostic markers for the newly diagnosed multiple myeloma (MM) patients. The clinical data of 114 newly diagnosed MM patients in the Second Affiliated Hospital of Kunming Medical University from January 2013 to March 2020 were retrospectively analyzed. Receiver operating characteristic (ROC) curve analysis was used to identify the optimal cutoff value, and the patients were divided into high LMR group and low LMR group (LMR≥3.35 and LMR < 3.35). Moreover, the patients were divided into four groups according to initial diagnosis LMR and LMR after four courses of treatment (LMR4): Group A (LMR≥3.35, LMR4≥3.35), Group B (LMR≥3.35, LMR4 < 3.35), Group C (LMR < 3.35, LMR4≥3.35), and group D (LMR < 3.35, LMR4 < 3.35). The simple prognosis model was established by combined with LMR and cCa, the patients were divided into Group a (no risk factor), group b (1 risk factor) and Group c (2 risk factors). Independent sample T-test, Pearson Chi-square test or Mann-Whitney U test were used to evaluate the differences between various parameters, and Kaplan-Meier method and Cox regression were used for survival analysis. The median follow-up time was 13.05（0.1-72.5）months. Survival analysis showed that the patients with low LMR predicted poor prognosis, the overall survival (OS) time of the patients with low LMR was significantly shorter (17 vs 50.5 months, P=0.006) than the patients with high LMR, the difference was also significant between group A and Group D (56.5 vs 30.5 months, P=0.043). The OS of the patients was also significantly shorter in the high cCa group (≥2.75 mmol/L) compared with normal group (8.5 vs 34 months, P=0.006). Multivariate survival analysis showed that LMR < 3.35 (P=0.028) and cCa≥2.75 mmol/L (P=0.036) were the independent risk factors affecting prognosis of MM patients. The comparison of risk factors showed that the median OS of Group a, b and c was 50, 20, and 8.5 months, respectively. The prognosis of the patients without risk factors was better than that of patients with 1-2 risk factors (Group a vs Group b, P < 0.0001; Group a vs Group c, P=0.002). LMR and cCa are the independent risk factors affecting the prognosis of newly diagnosed MM patients, and the development of a simple prognosis system combining them can quickly identify the prognosis of newly diagnosed MM patients.

Continuation of Lorlatinib in ALK-Positive NSCLC Beyond Progressive Disease

IntroductionLorlatinib, a potent, selective third-generation ALK tyrosine kinase inhibitor (TKI), exhibited overall and intracranial antitumor activity in patients with ALK-positive NSCLC. MethodsRetrospective analyses in the ongoing phase 2 trial (NCT01970865) investigated the clinical benefit of continuing lorlatinib beyond progressive disease (LBPD). Patients with previous crizotinib treatment as the only ALK TKI were group A (n = 28); those with at least one previous second-generation ALK TKIs were group B (n = 74). LBPD was defined as greater than 3 weeks of lorlatinib treatment after investigator-assessed progressive disease. Only patients with the best overall response of complete or partial response or stable disease were included. ResultsThere were no major differences in baseline characteristics between groups. The median duration of treatment for patients who continued LBPD was 32.4 months (group A) and 16.4 months (group B) versus 12.5 months (group A) and 7.7 months (group B) for patients who did not continue LBPD. The median overall survival in group A was not reached (NR) in patients who continued LBPD versus 24.4 months (95% confidence interval [CI]: 12.1–NR); group B’s median was 26.5 months (95% CI: 18.7–35.5) in patients who continued LBPD versus 14.7 months (95% CI: 9.3–38.5) in patients who did not continue LBPD. The median overall survival postprogression for groups A and B was NR (95% CI: 21.4–NR) and 14.6 months (95% CI: 11.2–19.2) in patients who continued LBPD and 8.0 months (95% CI: 1.5–NR) versus 5.3 months (95% CI: 2.8–14.3) in patients who did not continue LBPD. ConclusionsContinuing LBPD is a viable treatment strategy for select patients with ALK-positive NSCLC who progressed on lorlatinib.

The Pattern of Care for Brain Metastasis from Breast Cancer over the Past 10 Years in Korea: A Multicenter Retrospective Study (KROG 16-12).

PurposeWe aimed to investigate manifestations and patterns of care for patients with brain metastasis (BM) from breast cancer (BC) and compared their overall survival (OS) from 2005 through 2014 in Korea.Materials and MethodsWe retrospectively reviewed 600 BC patients with BM diagnosed between 2005 and 2014. The median follow-up duration was 12.5 months. We categorized the patients into three groups according to the year when BM was initially diagnosed (group I [2005–2008], 98 patients; group II [2009–2011], 200 patients; and group III [2012–2014], 302 patients).ResultsOver time, the median age at BM diagnosis increased by 2.2 years (group I, 49.0 years; group II, 48.3 years; and group III, 51.2 years; p=0.008). The percentage of patients with extracranial metastasis was 73.5%, 83.5%, and 86.4% for group I, II, and III, respectively (p=0.011). The time interval between BC and BM was prolonged in patients with stage III primary BC (median, 2.4 to 3 years; p=0.029). As an initial brain-directed treatment, whole-brain radiotherapy alone decreased from 80.0% in 2005 to 41.1% in 2014. Meanwhile, stereotactic radiosurgery or fractionated stereotactic radiotherapy alone increased from 13.3% to 34.7% during the same period (p=0.005). The median OS for group I, II, and III was 15.6, 17.9, and 15.0 months, respectively, with no statistical significance.ConclusionThe manifestations of BM from BC and the pattern of care have changed from 2005 to 2014 in Korea. However, the OS has remained relatively unchanged over the 10 years.

A Retrospective Analysis of the Effect of Anlotinib in Patients With Lung Cancer With or Without Previous Antiangiogenic Therapy.

ObjectiveThe purpose of this study was to initially investigate the effect of previous antiangiogenic therapy (bevacizumab and endostatin) on the efficacy of anlotinib in patients with advanced or metastatic lung cancer (LC).MethodsWe retrospectively collected the clinical data of patients with LC treated with anlotinib and divided them into group A (treated with anlotinib after the failure of previous antiangiogenic drugs and group B (no prior use of antiangiogenic drugs). We used propensity score matching (PSM) for confounding factors between the groups. Progression-free survival (PFS) and overall survival (OS) were also recorded.ResultsA total of 160 patients were included in the analysis. The median OS in groups A and group B was 11.8 months and 16.1 months (P=0.120), whereas the median PFS was 3.1 months and 4.7 months (P=0.009), respectively. Moreover, the objective response rate (ORR) of the two groups was 9.6% and 10.4% (P=0.874), and the disease control rate (DCR) was 71.1% and 80.5% (P=0.165).After PSM (n=46), baseline characteristics were comparable between groups A and B. Furthermore, the median OS of the two groups was 14.6 months and 16.2 months (P=0.320), whereas the median PFS was 3.5 months and 4.5 months (P=0.040), respectively. Moreover, the ORR of the two groups were 13.0% and 10.9% (P=0.748), and the DCR were 78.3% and 82.6% (P=0.599), respectively.ConclusionsPrevious antiangiogenic treatments may affect the PFS of patients who receive anlotinib later, but it might not affect the patient’s ORR and OS.

Clinical stages of recurrent hepatocellular carcinoma: A retrospective cohort study.

BACKGROUNDHepatocellular carcinoma (HCC) is the second leading cause of cancer-related death worldwide, and has relatively high recurrence rates. Few studies have been published on the clinical stages of recurrent HCC.AIMTo assess the applicability of the Barcelona Clinic Liver Cancer (BCLC) staging for recurrent HCC and the need to establish clinical stage criteria for recurrent HCC.METHODSThe clinicopathological data of 81 patients with recurrent HCC who were admitted to the Hospital of Guangxi Zhuang Autonomous Region from January 2013 to December 2017 were collected. The patients were divided into three groups according to the BCLC staging system as follows: (1) Group A with BCLC stage A, 51 patients; (2) Group B with BCLC stage B, 14 patients; and (3) Group C with BCLC stage C, 16 patients. The median time to tumor recurrence and the median overall survival were compared. RESULTSThe median time to tumor recurrence in groups A, B, and C was 16 ± 1.5 mo, 10 ± 2.8 mo, and 6 ± 0.5 mo, respectively, with a statistically significant difference among them (χ2 = 70.144, P < 0.05); no statistically significant difference was noted between group A and group B (χ2 = 2.659, P > 0.05), although there were statistically significant differences between group A and group C and between group B and group C (χ2 = 62.110, and 19.972, P < 0.05). The median overall survival in groups A, B, and C were 42 ± 5.1 mo, 22 ± 3.1 mo, and 13 ± 1.8 mo, respectively, with a statistically significant difference among them (χ2 = 38.949, P < 0.05); there were statistically significant differences between group A and group B, group A and group C, and group B and group C (χ2 = 9.577, 37.172, and 7.183, respectively; P < 0.05).CONCLUSIONThere are different prognoses in recurrent HCC patients according to the BCLC staging. Therefore, BCLC staging is applicable to recurrent HCC and it is essential to formulate clinical stage criteria for recurrent HCC.
