Median Overall Survival For Patients Research Articles

Clinical characteristics and prognosis of patients with therapy-related myelodysplastic syndrome and acute myeloid leukemia arising from malignant tumors

Objective: To investigate the clinical characteristics, cytogenetics, molecular biology, treatment, and prognosis of patients with therapy-related myelodysplastic syndrome and acute myeloid leukemia (t-MDS/AML) secondary to malignancies. Methods: The clinical data of 86 patients with t-MDS/AML in West China Hospital of Sichuan University between January 2010 and April 2023 were retrospectively analyzed. The clinical characteristics, primary tumor types, and tumor-related therapies were analyzed. Results: The study enrolled a total of 86 patients with t-MDS/AML, including 67 patients with t-AML, including 1 patient with M(0), 6 with M(1), 27 with M(2), 9 with M(3), 12 with M(4), 10 with M(5), 1 with M(6), and 1 with M(7). Sixty-two patients could be genetically stratified, with a median overall survival (OS) of 36 (95% CI 22-52) months for 20 (29.9%) patients in the low-risk group and 6 (95% CI 3-9) months for 10 (14.9%) in the intermediate-risk group. The median OS time was 8 (95% CI 1-15) months in 32 (47.8%) patients in the high-risk group. For patients with non-acute promyelocytic leukemia (APL) and AML, the median OS of the low-risk group was 27 (95% CI 18-36) months, which was significantly longer than that of the non-low-risk group (χ(2)=5.534, P=0.019). All 9 APL cases were treated according to the initial treatment, and the median OS was not reached, and the 1-, 2-, and 3-year OS rates were 100.0%, (75.0±6.2) %, and (75.0±6.2) % respectively. Of the 58 patients with non-APL t-AML (89.7%), 52 received chemotherapy, and 16 achieved complete remission (30.8%) after the first induction chemotherapy. The 1-, 2-, and 3-year OS rates of the non-APL t-AML group were (42.0 ± 6.6) %, (22.9±5.7) %, and (13.4±4.7) %, respectively. The median OS of patients who achieved remission was 24 (95% CI 18-30) months, and the median OS of those who did not achieve remission was 6 (95% CI 3-9) months (χ(2)=10.170, P=0.001). Bone marrow CR was achieved in 7 (53.8%) of 13 patients treated with vineclar-containing chemotherapy, with a median OS of 12 (95% CI 9-15) months, which was not significantly different from that of vineclar-containing chemotherapy (χ(2)=0.600, P=0.437). In 19 patients with t-MDS, the 1-, 2-, and 3-year OS rates were (46.8±11.6) %, (17.5±9.1) %, and (11.7±9.1) % with a median OS of 12 (95% CI 7-17) months, which was not significantly different from that in t-AML (χ(2)=0.232, P=0.630) . Conclusions: Breast cancer, bowel cancer, and other primary tumors are common in patients with t-MDS/AML, which have a higher risk of adverse genetics. Patients with APL had a high induction remission rate and a good long-term prognosis, whereas patients without APL had a low remission rate and a poor long-term prognosis.

Prognostic significance of extramedullary disease (EMD) detected on pre-transplant 18F-FDG PET/CT in patients with multiple myeloma: Results of PIPET-M trial

BackgroundIt is difficult to prognosticate the post-Autologous Stem Cell Transplant (ASCT) responses in multiple myeloma (MM) with the currently available prognostication models. 18F-FDGPET/CT has numerous advantages to prognosticate the post-transplant responses by assessing extramedullary disease (EMD) in addition to the extent of active disease. We aimed at identifying the prognostic value of EMD in predicting progression-free survival (PFS) and overall survival (OS). MethodsThis is a single centre prospective study from western India during a study period of 2014–2022 (with a median follow-up of patients of 6 years). All ASCT patients underwent 18F-FDG-PET/CT as part of pre-transplant workup. The conditioning and treatment protocols were not modified based on PET/CT findings. EMD on PET/CT was correlated with pre-transplant biochemical markers and post-ASCT survival/ progression (as defined by revised IMWG criteria). Statistical analysis was done using SPSS ver. 20. ResultsPatients with pre-ASCT EMD had a hazard-ratio for post-transplant all-cause mortality of 5.46 (p-0.045). Pre-transplant β2M and LDH were significantly higher in patients with EMD (p-0.036). The 6-year median OS in patients with and without EMD were 57.1%, and 80.6% respectively. Kaplan-Meier analysis showed poorer OS in patients with EMD χ2 (1–0.496, p-0.481). There was no significant difference in clinical or biochemical EFS among patients with EMD. ConclusionEMD detected on 18F-FDG-PET/CT has a higher hazard for mortality and is significantly correlated with pre-transplant higher β2M and LDH levels. Thus, EMD by pre-transplant 18F-FDG-PET/CT has a significant prognostic role.

Effect of blood type on mortality among patients with brain metastases

ObjectiveABO blood type has been associated with mortality among patients with cancer, but this association has thus far not been investigated among patients with brain metastases. Hence, we aimed to investigate the association between ABO blood type and mortality among patients who underwent surgical resection of brain metastases. MethodsA single-center retrospective study of patients who underwent surgical resection of brain metastases between 2011 and 2019 was conducted. Cox proportional hazards models were constructed, adjusting for potential confounders, to evaluate whether blood type was independently associated with overall mortality. ResultsA total of 158 patients were included in the analysis. The mean (SD) age of the cohort was 59.3 (12.0) years, and 67.7% of patients were female. The median overall survival of patients with blood type AB was 11.2 months, while the median overall survival of patients with blood types O, B, and A were 11.7, 13.5, and 14.4 months respectively. On univariate analysis, patients with blood type AB had a higher risk of overall mortality (p = 0.017). On multivariate analysis adjusting for potential confounders, blood type AB was again associated with a higher risk of overall mortality (HR: 2.29, 95% CI: 1.11–4.72, p = 0.025). ConclusionBlood type AB was independently associated with a higher risk of overall mortality among patients who underwent surgical resection of brain metastases, indicating the potential prognostic value of ABO blood type in brain metastases.

Early T-Cell Precursor Leukemia: A High-Risk Subtype of Acute Lymphoblastic Leukemia, Single Center Experience in Jordan

Background and ObjectivesEarly T-cell precursor (ETP) acute lymphoblastic leukemia/lymphoma (ALL/LBL) is a newly recognized entity of T-lymphoblastic leukemia/lymphoma. The optimal therapeutic approaches to adult patients are poorly studied. Patients and MethodsWe compared the outcomes of adult's patents with ETP-ALL/LBL who received frontline chemotherapy regimens with other T-ALL/LBL immunophenotypic subtypes. Patients with ETP-ALL/LBL were identified based on CD1a (-), CD8 (-), CD5 (-) (dim), and positivity for 1 or more stem cell or myeloid antigens. ResultsSixty-nine patients were included between the years 2010 and 2021 (19 ETP-T-ALL/LBL; 50 non ETP- T-cell ALL/LBL). The median age was 26 year (IQR: 21, 33). Fifty-six patients presented as ALL, while 16 with lymphoblastic lymphoma. Forty-seven patients achieved complete remission, and 43 were alive at last encounter. The complete remission rate in patients with ETP-ALL/LBL was lower than that of non-ETP-ALL/LBL patients (32% vs. 68%; P = .2), and the MRD at end of induction was significantly higher (26% vs. 6.2%, P < .001), and more likely to receive allo-SCT consolidation in CR1 (95% vs. 40%, P < .001). After a median follow-up of survivors of 48 months (range: 32-74 months), the median overall survival for patients with ETP-ALL/LBL was not reached versus 11.5 months for the non-ETP-ALL/LBL patients (P = .014)). Twenty-six patients receive allo-SCT in CR1. There was no significant difference in overall survival (79% vs. 70%; P = .49) between both transplant-cohorts in both groups. ConclusionETP-ALL/LBL represents a high-risk disease subtype of adult ALL. Novel treatment strategies are needed to improve treatment outcomes in this patient's population

Transhepatectomy combined with arterial chemoembolization and transcatheter arterial chemoembolization in the treatment of hepatocellular carcinoma: a clinical prognostic analysis

BackgroundThe prognosis of patients undergoing hepatectomy combined with transarterial chemoembolization (TACE) and TACE alone was examined in order to better understand the role of hepatectomy in the treatment of hepatocellular carcinoma (HCC). In this work, we also created a model and investigated the variables influencing overall survival (OS) in HCC patients.MethodsRetrospective analysis of 1083 patients who received TACE alone as the control group and 188 patients who received TACE after surgery in a total of 1271 HCC patients treated with LR + TACE or TACE at three third-class hospitals in China. It was done using the Propensity Score Matching (PSM) technique. The differences in OS between the two groups were compared, and OS-influencing factors were looked at. The main endpoint is overall survival. In this study, the COX regression model was used to establish the nomogram.ResultsThe median OS of the LR + TACE group was not attained after PSM. The median OS for the TACE group was 28.8 months (95% CI: 18.9–38.7). The median OS of the LR + TACE group was higher than that of the TACE group alone, indicating a significant difference between the two groups (χ2 = 16.75, P < 0.001). While it was not achieved in the LR + TACE group, the median OS for patients with lymph node metastases in the TACE group alone was 18.8 months. The two groups differed significantly from one another (χ2 = 4.105, P = 0.043). In patients with distant metastases, the median OS of the LR + TACE treatment group was not achieved, and the median OS of the TACE group alone was 12.0 months. The difference between the two groups was sizable (χ2 = 5.266, P = 0.022). The median OS for patients with PVTT following PSM was 30.1 months in the LR + TACE treatment group and 18.7 months in the TACE alone group, respectively. The two groups differed significantly from one another (χ2 = 5.178, P = 0.023); There was no discernible difference between the two groups in terms of median overall survival (OS), which was 30.1 months for patients with lymph node metastasis and 19.2 months for those without (P > 0.05); Regarding the median OS for patients with distant metastases, which was not achieved and 8.5 months, respectively, there was a significant difference between the two groups (χ2 = 5.759, P = 0.016). We created a new nomogram to predict 1-, 2-, and 3-year survival rates based on multiple independent predictors in COX multivariate analysis. The cohort's C-index is 0.705. The area under the curve (AUC value) for predicting 1-, 2-, and 3-year survival rates were shown by the subject operating characteristic (ROC) curve linked to the nomogram to be 0.730, 0.728, and 0.691, respectively.ConclusionsLR + TACE can increase OS, delay tumor recurrence, and improve prognosis in HCC patients when compared to TACE alone. Additionally, the nomogram we created does a good job of forecasting the 1-year survival rate of hepatocellular carcinoma.

Real-world clinical outcomes in patients with relapsed and refractory multiple myeloma receiving VTD-PACE treatment in the era of monoclonal antibodies.

Bortezomib (Velcade), thalidomide, dexamethasone, platinum (cisplatin), adriamycin (doxorubicin), cyclophosphamide, and etoposide (VTD-PACE) are commonly used as salvage treatment for patients with relapsed/refractory multiple myeloma (RRMM). However, its outcomes in the era of monoclonal antibodies remain unclear. Therefore, this retrospective cohort study assessed the clinical outcomes of 60 patients with RRMM (median four prior treatment lines) administered VTD-PACE. The median follow-up period was 11.1months, during which they received a median of two cycles of VTD-PACE. The overall response rate (ORR) was 66.7%; ORRs of 53.1 and 82.1% were noted in patients with ≥ 4 and ≤ 3 prior lines (P = 0.027), respectively. The median overall survival (OS) was 17months, with a median progression-free survival (PFS) of 9.8months. Using the 3-month time point after VTD-PACE treatment as a landmark, 54 patients were still alive. Landmark analysis was conducted for PFS and OS of patients who received or did not receive HSCT or CART after VTD-PACE treatment. Patients who underwent subsequent hematopoietic stem cell transplantation (HSCT) or chimeric antigen receptor T-cell therapy (CART) following VTD-PACE showed a trend of longer PFS and OS than those who did not undergo subsequent HSCT or CART. The median OS in patients with and without renal dysfunction was 10.7months and 21.5months, respectively (P = 0.0091). Therefore, VTD-PACE is useful as a bridging therapy for HSCT or CART, as a response can be expected regardless of organ damage, disease risk, or history of anti-CD38 antibody use.

HIPEC and PIPAC for gastric cancer: technique and comparison of efficacy. Literature review

Background: According to the World Health Organization (WHO) data, gastric cancer (GC) was the 5th most common cancer and the 4th leading cause of cancer death worldwide in 2020. Peritoneal metastases (PM) are associated with a poor prognosis and detected in 30 % of patients with locally advanced GC; the median overall survival in patients with PM is 3–6 months without any treatment and 6–12 months with the use of systemic chemotherapy. Delivery of appropriate chemotherapeutic drugs directly into the abdominal cavity increases the effectiveness of treatment without severe systemic side effects. Today, various forms of intra-abdominal chemotherapy of PM are used in the world.Aim: To evaluate the efficacy of hyperthermic intraperitoneal chemotherapy (HIPEC) and aerosol intraperitoneal pressure chemotherapy (PIPAC) in the treatment of GC PM.Purposes: To review current domestic and foreign publications on HIPEC and PIPAC, to compare their efficacy.Materials and methods: Articles in PubMed, Scopus, Web of Science databases were studied and analyzed for the key queries: “stomach cancer”, “carcinomatosis”, “peritoneal metastases”, “HIPEC”, “PIPAC”.Conclusions: The best results were achieved when using PIPAC as preoperative chemotherapy, followed by cytoreductive surgery in combination with HIPEC. Both procedures are promising and require further study with multicenter randomized prospective trials to assess their therapeutic potential.

Real-world experience of tyrosine kinase inhibitors in children, adolescents and adults with relapsed or refractory bone tumours: A Canadian Sarcoma Research and Clinical Collaboration (CanSaRCC) study.

We conducted a retrospective multi-centre study to assess the real-world outcome of regorafenib (REGO) and cabozantinib (CABO) in recurrent/refractory bone tumours (BTs) including osteosarcoma (OST), Ewing sarcoma (EWS) and chondrosarcoma (CS)/extra-skeletal mesenchymal CS (ESMC). After regulatory approval, data from patients with recurrent BT (11 institutions) were extracted from CanSaRCC (Canadian Sarcoma Research and Clinical Collaboration) database. Patient characteristics, treatment and outcomes were collected. Progression-free survival (PFS) and overall survival (OS) were estimated using the Kaplan-Meier method. From July 2018 to May 2022, 66 patients received REGO or CABO; 39 OST, 18 EWS, 4 CS and 5 ESMC. Median age was 27.8 years (range 12-76); median starting dose was 60 mg for CABO (n = 37, range 40-60) and 120 mg for REGO (n = 29, range 40-160). Twenty-eight (42.4%) patients required dose reduction: hand-foot syndrome 7 (10.6%), nausea/vomiting 1 (1.5%), diarrhoea 1 (1.5%), 2 elevated LFTs (3%), elevated bilirubin 1 (1.5%) and mucositis 1 (1.5%). The median OS for patients with OST, EWS, CS and ESMC was 8.5 months (n = 39, 95% CI 7-13.1); 13.4 months (n = 18, 95% CI 3.4-27.2), 8.1 (n = 4, 95% CI 4.1-9.3) and 18.2 (n = 5, 95% CI (10.4-na), respectively. Median PFS for OST, EWS, CS and ECMS was 3.5 (n = 39, 95% CI 2.8-5), 3.9 (n = 18, 95% CI 2.1-5.9), 5.53 (n = 4. 95% CI 2.13-NA) and 11.4 (n = 5, 95% CI 1.83-14.7), respectively. Age, line of therapy, REGO versus CABO, or time from diagnosis to initiation of TKI were not associated with PFS on univariable analysis. Our real-world data show that TKIs have meaningful activity in recurrent BT with acceptable toxicities when started at modified dosing. Inclusion of TKIs in earlier lines of treatment and/or maintenance therapy could be questions for future research.

Retrospective evaluation of our patients diagnosed with advanced pancreatic cancer

Aims: Pancreatic cancer attracts attention with its increasing frequency among gastrointestinal cancers. It has the worst prognosis of all cancer types. In this study, we aimed to retrospectively evaluate the clinical features and treatment results of our patients with advanced pancreatic cancer. Methods: In this study, 131 patients diagnosed with advanced pancreatic cancer and admitted to the Ankara Numune Training and Research Hospital Medical Oncology Polyclinic between November 2002 and January 2014 were retrospectively analyzed. Demographic characteristics of the patients, smoking, family history, basal CEA and basal CA 19-9 levels, treatment modalities, metastasis sites, progression-free survival, and overall survival times were evaluated. Results: The study population consisted of 131 patients, including 94 males and 37 females. Twenty of the patients were in the locally advanced stage, and 111 were in the metastatic stage. The median age of the patients was 60 years. 53.4% of the patients were smokers, and the median amount of smoking was 30 packs/year. Adenocancer was the most common histopathological subtype. The median basal CEA and Ca 19-9 levels were high at the time of diagnosis. Neoadjuvant chemotherapy was given to all locally advanced patients. The most commonly used chemotherapy regimens were single-agent gemcitabine and gemcitabine-cisplatin combination therapies. While 10 of the locally advanced patients received local treatment (chemotherapy or surgery) after neoadjuvant chemotherapy, the remaining 10 patients could not receive local treatment. The median overall and progression-free survival times were found to be significantly longer in patients with locally advanced disease who received local treatment after neoadjuvant chemotherapy [(18 months vs. 6.5 months; p=0.008), (11.3 months vs. 6.4 months; p=0.05)]. The most common site of metastasis in our patients with metastatic pancreatic cancer was the liver (80%). Cisplatin-gemcitabine was preferred as a KT regimen in 63.4% of metastatic cases. The median overall survival time of the patients in the metastatic stage was 8.1 months, and the median progression-free survival time was 5.7 months. The median progression-free survival of all patients included in the study was 6.2 months, while the median overall survival was 8.8 months. Conclusion: The median overall survival of patients with locally advanced pancreatic cancer was significantly longer compared to metastatic patients (18 months vs. 8.1 months; p=0.028). Progression-free survival and overall survival of patients with locally advanced disease who received or did not receive local treatment after neoadjuvant chemotherapy were found to be significantly longer in patients who received local treatment. (11.3 months vs. 6.4 months; p=0.05) (18 months vs. 6.5 months; p=0.008). Response rates of patients with metastatic pancreatic cancer; It was 49% in the gemcitabine-cisplatin combination arm and 30% in the single-agent gemcitabine arm.

Arterial enhancement on triphasic computed tomography scan predicts response of colorectal liver metastases to chemoembolization: A case–control study

Objectives: The arterial enhancement fraction (AEF), a simple calculation based on a standard triple-phase computed tomography (CT) scan, has been shown to predict treatment response in radioembolization of colorectal liver metastases (CRLM). The current study aims to determine if arterial enhancement also predicts treatment response in transarterial chemoembolization (TACE) of CRLM, which uses a larger particle size and exerts an ischemic effect. Materials and Methods: A retrospective analysis of our experience with TACE for CRLM between 2013 and 2022 yielded 97 TACE treatments for CRLM. The study included the first TACE treatment patients having a triple-phase CT scan before and after TACE, yielding 62 tumors treated with TACE of irinotecan drug-eluting beads in 36 patients. Tumors with complete response or partial response based on CT-based modified RECIST criteria were considered to be “responders,” whereas tumors that had progressive disease or stable disease were considered to be “non-responders.” Results: The responders differed from the non-responders in terms of arterial phase enhancement (APhE) (9.5 [interquartile range, IQR 6, 17] vs. 2 [IQR 1, 5] Hounsfield units [HUs], P &lt; 0.001) and AEF (0.7 [IQR 0.5, 1] vs. 0.3 [IQR 0.1, 1], P = 0.01), both validated measures of hepatic arterial perfusion. Receiver operating characteristic curve analysis yielded a 5.5 HU cutoff for APhE. Those tumors with APhE &gt;5.5 HU had a response rate of 72%, whereas those &lt;5.5 HU had a response rate of 21%. Median overall survival for patients with tumors having APhE &gt;5.5 HU was 22.4 months (IQR 13, 32) versus 14.5 months (IQR 10, 19) for those with APhE ≤5.5 HU, but this did not achieve statistical significance (P = 0.14). Conclusion: CRLM with greater hepatic arterial blood supply as measured by the APhE and AEF have a higher probability of TACE treatment response.

Cox proportional hazards deep neural network identifies peripheral blood complete remission to be at least equivalent to morphologic complete remission in predicting outcomes of patients treated with azacitidine-A prospective cohort study by the AGMT.

The current gold standard of response assessment in patients with myelodysplastic syndromes (MDS), chronic myelomonocytic leukemia (CMML), and acute myeloid leukemia (AML) is morphologic complete remission (CR) and CR with incomplete count recovery (CRi), both of which require an invasive BM evaluation. Outside of clinical trials, BM evaluations are only performed in ~50% of patients during follow-up, pinpointing a clinical need for response endpoints that do not necessitate BM assessments. We define and validate a new response type termed "peripheral blood complete remission" (PB-CR) that can be determined from the differential blood count and clinical parameters without necessitating a BM assessment. We compared the predictive value of PB-CR with morphologic CR/CRi in 1441 non-selected, consecutive patients diagnosed with MDS (n = 522; 36.2%), CMML (n = 132; 9.2%), or AML (n = 787; 54.6%), included within the Austrian Myeloid Registry (aMYELOIDr; NCT04438889). Time-to-event analyses were adjusted for 17 covariates remaining in the final Cox proportional hazards (CPH) model. DeepSurv, a CPH neural network model, and permutation-based feature importance were used to validate results. 1441 patients were included. Adjusted median overall survival for patients achieving PB-CR was 22.8 months (95%CI 18.9-26.2) versus 10.4 months (95%CI 9.7-11.2) for those who did not; HR = 0.366 (95%CI 0.303-0.441; p < .0001). Among patients achieving CR, those additionally achieving PB-CR had a median adjusted OS of 32.6 months (95%CI 26.2-49.2) versus 21.7 months (95%CI 16.9-27.7; HR = 0.400 [95%CI 0.190-0.844; p = .0161]) for those who did not. Our deep neural network analysis-based findings from a large, prospective cohort study indicate that BM evaluations solely for the purpose of identifying CR/CRi can be omitted.

Efficacy of apatinib combined with temozolomide in the treatment of recurrent high‑grade glioma: A meta‑analysis.

Recurrent high-grade glioma is a refractory disease, and its prognosis is poor. Although the treatment of apatinib combined with temozolomide provides improved efficacy and is able to prolong survival, this conclusion has been based on small samples. In order to clarify this treatment's efficacy, a meta-analysis was performed in the present study. Different databases were screened and finally, 10 studies were included, comprising 357 patients with recurrent high-grade gliomas. The efficacy and prognosis were analyzed using Stata software. The results indicated that the overall objective response rate (ORR) and disease control rate (DCR) of apatinib combined with temozolomide were 0.36 (95% CI, 0.26-0.46) and 0.86 (95% CI, 0.82-0.89), respectively. Subgroup analysis indicated that the overall ORR was 0.43 (95% CI, 0.29-0.57) and 0.26 (95% CI, 0.14-0.38), and the DCR was 0.89 (95% CI, 0.85-0.93) and 0.76 (95% CI, 0.69-0.84) in the treatment of apatinib with temozolomide dose-dense group and the conventional-dose group (5/28 regimen), respectively. Further prognostic analysis indicated that the median overall survival of patients with high-grade glioma treated with apatinib combined with temozolomide was 8.21 months (95% CI, 7.20-9.22 months) and the median progression-free survival was 5.45 months (95% CI, 4.53-6.37). Analysis of the publication bias of the effect size revealed that there was bias in the DCR, while no bias was found in the remaining effect size (ORR, median overall survival and median progression-free survival). After correction by the trim-and-fill method, bias was indicated to have no significant impact on the results. In conclusion, apatinib combined with temozolomide has the effect that, compared with traditional Bevacizumab treatment, it can improve the efficacy in the treatment of recurrent high-grade glioma and improve prognosis. When combining with dose-dense temozolomide, the effect may be better than that of the conventional 5/28 regimen.

Sarcopenia in Men With Bone-Predominant Metastatic Castration-Resistant Prostate Cancer Undergoing Ra-223 Therapy.

Osteosarcopenia is the progressive loss of musculoskeletal structure and functionality, contributing to disability and mortality. Despite complex interactions between bone and muscle, osteosarcopenia prevention and treatment in men with metastatic castration-resistant prostate cancer (mCRPC) focuses predominantly on bone health. It is unknown whether Radium-223 (Ra-223) therapy affects sarcopenia. We identified 52 patients with mCRPC who had received Ra-223 and had a baseline plus ≥1 follow-up abdominopelvic CT scan. The total contour area (TCA) and averaged Hounsfield units (HU) of the left and right psoas muscles were obtained at the inferior L3 endplate, and the psoas muscle index (PMI) was calculated therefrom. Intrapatient musculoskeletal changes were analyzed across various time points. TCA and PMI gradually declined over the study period (P = .002, P = .003, respectively), but Ra-223 therapy did not accelerate sarcopenia, nor the decline of HU compared to the pre-Ra-223 period. The median overall survival of patients with baseline sarcopenia was numerically worse (14.93 vs. 23.23 months, HR 0.612, P = .198). Ra-223 does not accelerate sarcopenia. Thus, worsening muscle parameters in men with mCRPC undergoing Ra-223 therapy are attributable to other factors. Further research is needed to determine whether baseline sarcopenia predicts poor overall survival in such patients.

Clinical features and prognosis of advanced intra- and extra-pulmonary neuroendocrine carcinomas.

We examined the clinical features and prognosis of advanced intra- and extra-pulmonary neuroendocrine carcinomas (NECs) to offer additional guidance for the clinical treatment of small-cell lung cancer (SCLC), which is a type of advanced intrapulmonary NEC (IPNECs). The clinical data and survival of 123 patients with advanced IPNECs and extrapulmonary NECs (EPNECs) were obtained. We retrospectively examined the corresponding clinical diagnosis and treatment and investigated the significant factors influencing the survival prognosis of patients with NECs. There were 90 cases of IPNECs (including 81 cases of SCLC), and 33 cases of EPNECs. The median overall survival (OS) of IPNECs was significantly longer than that of the EPNECs in the gastrointestinal tract and in the other regions (P < 0.05). The median OS of patients with other IPNECs was longer than that of patients with SCLC (P > 0.05). Multivariate analysis demonstrated that age, liver metastasis, number of cycles of first-line chemotherapy, and chest radiotherapy were risk factors influencing OS in patients with NECs (P < 0.05). The survival of IPNECs was significantly longer than that of EPNECs in the gastrointestinal tract and other regions. Nevertheless, patients with advanced NECs who were older and had liver metastases had a poorer prognosis. Multidisciplinary treatments including multicycle chemotherapy and a combination of chemotherapy and radiotherapy should function significantly in extending the survival of NECs.

Experience of using talazoparib in the aggressive course of BRCA2-associated triple-negative breast cancer: a clinical observation

The median overall survival for patients with metastatic triple-negative breast cancer is about 12-14 months. Chemotherapy has been the only treatment option for this tumour subtype for a long time, irrespective of immunological and genetic characteristics. Straightforward therapy algorithms have not been defined, and the optimum sequencing of chemotherapy regimens is left to the discretion of the attending physician. Today, impressive findings from clinical studies on the use of immunotherapy and targeted therapy for cancer using PARP inhibitors reflect in current guidelines, raising the chances of patients to prolong life and maintain its high quality. Thus, the use of immunotherapy as first-line treatment of PD-L1-positive tumours allowed to significantly increase the overall survival of patients for the first time in many years. And the use of PARP inhibitors in carriers of BRCA1/2 germline mutations not only significantly prolongs progression-free survival, but also improves quality of life versus standard chemotherapy regimens. The benefit is also observed in patients with an aggressive course of the disease such as damage to the visceral organs and the central nervous system. The presence of BRCA1/2 germline mutations in the genes, damage to the CNS and visceral organs is associated with an extremely unfavourable prognosis and a significant decline in life expectancy. However, a high-quality diagnosis before initiation of treatment, creating proper treatment plans and the use of modern opportunities can improve the outcomes of treatment. The article discusses possible treatment options for metastatic TNBC, reflects current guidelines on the use of immuno- and targeted therapy. A clinical case report of the treatment of a patient with a significantly aggravated history and an aggressive course of TNBC is presented. The patient with visceral metastases, brain damage and early progression after primary treatment has been receiving therapy for two years, while maintaining a satisfactory quality of life.

Association of the CD4+/CD8+ ratio with response to PD-1 inhibitor-based combination therapy and dermatological toxicities in patients with advanced gastric and esophageal cancer

The host immune system affects the treatment response to immune checkpoint inhibitors and can be reflected by circulating immune cells. This study aimed to evaluate whether circulating T cell subtypes are correlated with clinical response and dermatological toxicities in patients with advanced gastric and esophageal cancer receiving PD-1 inhibitor-based combination therapy (n = 203). In the training cohort, Eastern Cooperative Oncology Group performance status (ECOG PS), PD-L1 expression, antibiotic use, and CD4+/CD8+ ratio were identified as independent prognostic factors in these patients, using a Cox regression model. A nomogram to predict the overall survival (OS) and survival probabilities was constructed using these factors. The nomogram showed good discrimination ability (C-index, 0.767) and was externally confirmed in the validation and test cohorts. Kaplan-Meier analysis showed that median OS in patients with a CD4+/CD8+ ratio ≥1.10 was 6.2 months, which was significantly shorter than that in patients with a CD4+/CD8+ ratio <1.10 (P < 0.001). Patients with a CD4+/CD8+ ratio <1.10 had a superior objective response (43.8% vs. 23.1%) and disease control (72.9% vs. 59.0%) rate, relative to those with ratio ≥ 1.10. In addition, PD-L1 expression, corticosteroid use, and CD4+/CD8+ ratio can independently predict dermatological toxicities. In conclusion, baseline CD4+/CD8+ ratio is a potential prognostic factor for patients with advanced gastric and esophageal cancer treated with PD-1 inhibitor-based combination therapy, and can independently predict dermatological toxicities. In addition, a nomogram incorporating CD4+/CD8+ ratio, ECOG PS, PD-L1 expression, and antibiotic use can predict OS with considerable accuracy.

Survival Trends and Profiling of Gastric Mixed Adenoneuroendocrine Carcinoma (gMANEC) in the Current Era

Background: Gastric mixed adenoneuroendocrine carcinoma (gMANEC) is a histopathologic diagnosis with at least 30% each of exocrine and endocrine components. Although prognosis is thought to be driven by the relative exocrine or endocrine dominance, gMANEC has been clinically treated as gastric adenocarcinoma (gAC). The overall survival of gMANEC as compared to gastric neuroendocrine carcinoma (gNEC) or gAC remains undefined. Methods: Using the National Cancer Database, patients with gastric tumors were queried from 2004 to 2016 for gMANEC, gNEC, and gAC histologies. Demographic and clinicopathologic features were recorded. Univariate and multivariate Cox proportional hazards analyses were performed to delineate factors associated with overall survival (OS). Results: Overall, 404 patients diagnosed with gMANEC were identified. Patients had a median age 68 years, were majority male, and predominantly Caucasian. Gastric MANEC was more frequently poorly differentiated (73%vs 52% (gAC) vs 20% (gNEC), P &lt; .001) with lymphovascular invasion (57%vs 38%vs 27%, P &lt; .001) and lymph node involvement (59%vs 49%vs 36%, P &lt; .001); these factors were associated with worse OS on univariable analysis. Finally, tumors &gt;5 cm and lymph node involvement were independent predictors of worse survival. The median OS of patients with gMANEC was 41.5 months. Conclusion: Gastric MANEC and gAC have a similarly dismal prognosis and thus should be continued to treat like gAC. Pathologic nodal metastasis, tumor size and grade are useful prognostic factors.

Outcome benefits of bevacizumab biosimilar (SIBP04) combined with carboplatin and paclitaxel in advanced non-squamous non-small-cell lung cancer patients with EGFR mutation: subgroup analysis of a prospective, randomized phase III clinical trial.

SIBP04 is a bevacizumab biosimilar, and bevacizumab combined with carboplatin and paclitaxel in advanced non-squamous non-small-cell lung cancer (nsqNSCLC) has been recommended as the first-line treatment choice. However, the efforts of bevacizumab combined with carboplatin and paclitaxel for nsqNSCLC patients with EGFR mutation remained unclear. Here we report an EGFR mutation subgroup analysis of a prospective, randomized phase III clinical trial (NCT05318443). In this randomized, double-blind, multi-center, parallel controlled, phase III clinical trial, locally advanced, metastatic NSCLC patients were enrolled, and EGFR expression was examined and considered as a stratification factor. All patients received 4 to 6 cycles of paclitaxel and carboplatin plus SIBP04 or bevacizumab 15mg/kg intravenously followed by SIBP04 15mg/kg maintenance until intolerable toxicity, disease progression or death. Patients with EGFR mutation and wild-type were assessed for progression-free survival (PFS) and overall survival (OS). EGFR expression was examined in 398 NSCLC patients (142 with EGFR mutation, 256 with EGFR wild type). PFS in EGFR mutation patients was significantly longer than EGFR wild-type patients (10.91 vs. 7.82months; HR = 0.692, 95% CI 0.519-0.921, P = 0.011). The median OS in patients with EGFR mutation was not reached while that of EGFR wild-type group was 17.54months (HR = 0.398, 95% CI 0.275-0.575, P < 0.001). However, there were no significant differences in objective response rate (61.97% vs. 55.86%, P = 0.237) or disease control rate (90.14% vs. 89.84%, P = 0.925). Bevacizumab combined with chemotherapy significantly prolonged the PFS and OS of advanced nsqNSCLC patients with EGFR mutation.

Intracranial Efficacy of Systemic Therapy in Patients with Asymptomatic Brain Metastases from Lung Cancer.

There has been controversy over whether to radiologically follow up or use local treatment for asymptomatic small-sized brain metastases from primary lung cancer. For brain tumors without local treatment, we evaluated potential factors related to the brain progression and whether systemic therapy controlled the tumor. We analyzed 96 patients with asymptomatic small-sized metastatic brain tumors from lung cancer. These underwent a radiologic follow-up every 2 or 3 months without local treatment of brain metastases. The pathologies of the tumors were adenocarcinoma (n = 74), squamous cell carcinoma (n = 11), and small cell carcinoma (n = 11). The primary lung cancer was treated with cytotoxic chemotherapy (n = 57) and targeted therapy (n = 39). Patients who received targeted therapy were divided into first generation (n = 23) and second or third generation (n = 16). The progression-free survival (PFS) of brain metastases and the overall survival (OS) of patients were analyzed depending on the age, tumor pathology, number, and location of brain metastases, the extent of other organ metastases, and chemotherapy regimens. The median PFS of brain metastases was 7.4 months (range, 1.1-48.3). Targeted therapy showed statistically significant PFS improvement compared to cytotoxic chemotherapy (p = 0.020). Especially, on univariate and multivariate analyses, the PFS in the second or third generation targeted therapy was more significantly improved compared to cytotoxic chemotherapy (hazard ratio 0.229; 95% confidence interval, 0.082-0.640; p = 0.005). The median OS of patients was 13.7 months (range, 2.0-65.0). Univariate and multivariate analyses revealed that the OS of patients was related to other organ metastases except for the brain (p = 0.010 and 0.020, respectively). Three out of 52 patients with brain recurrence showed leptomeningeal dissemination, while the recurrence patterns of brain metastases were mostly local and/or distant metastases (94.2%). Of the 52 patients who relapsed, 25 patients received local brain treatment. There was brain-related mortality in two patients (2.0%). The intracranial anti-tumor effect was superior to cytotoxic chemotherapy in the treatment of asymptomatic small-sized brain metastases with targeted therapy. Consequently, it becomes possible to determine the optimal timing for local brain treatment while conducting radiological follow-up for these tumors, which do not appear to increase brain-related mortality. Furthermore, this approach has the potential to reduce the number of cases requiring brain local treatment.

Prognostic impact of pre- and postoperative tumor markers in patients with intrahepatic cholangiocarcinoma.

The present study assessed the impact of pre- and postoperative tumor markers on the survival of patients with intrahepatic cholangiocarcinoma. Medical records of 73 patients with intrahepatic cholangiocarcinoma were reviewed retrospectively. The pre- and postoperative carcinoembryonic antigen and carbohydrate antigen 19-9 levels were assessed. Patient characteristics, clinicopathological factors, and prognostic factors were analyzed. The median recurrence-free survival and overall survival were 30.0 and 90.9months, respectively. A multivariate survival analysis revealed that elevated postoperative carbohydrate antigen 19-9 (p = 0.023) was the only independent poor prognostic factor. The median overall survival of patients with normal and elevated postoperative carbohydrate antigen 19-9 levels was 101.4 and 15.7months (p < 0.001), respectively. Multivariate logistic regression identified elevated preoperative carbohydrate antigen 19-9 as an independent preoperative risk factor for elevated postoperative carbohydrate antigen 19-9. The optimal cutoff value of preoperative carbohydrate antigen 19-9 for predicting elevated postoperative carbohydrate antigen 19-9 was 40 U/mL, with a sensitivity and specificity of 92% and 87%, respectively (area under curve = 0.915). Elevated postoperative carbohydrate antigen 19-9 was an independent poor prognostic factor. Preoperative predictors, such as elevated preoperative carbohydrate antigen 19-9, may indicate the need for neoadjuvant therapies to improve the survival.
