Association between muscle mass and overall survival among colorectal cancer patients at tertiary cancer center in the Middle East

Recent reports have shown that pre-treatment low muscle mass may lead to poorer outcomes for cancer patients. We explored the correlation between Visceral Adipose Tissue (VAT), Subcutaneous Adipose Tissue (SAT), and Muscle Mass (MM) as measured by CT scans, and overall survival (OS) following diagnosis of colorectal cancer (CRC). We conducted a retrospective review of medical records and CT scans of patients diagnosed with CRC between 2007 and 2018. Demographics, pathology, and clinical parameters were collected. Using Image-J software, we measured VAT, SAT, and MM. Survival rates were analyzed using Kaplan–Meier curves, and prognostic factors were assessed using multivariate Cox regression. Analysis included 408 patients with a mean age of 56.9 years and a median follow-up of 93.3 months. Colon and rectum/rectosigmoid colon cancers were equally distributed. The 5-year OS rate was 67.8%. There was no significant difference in OS rates based on SAT or VAT. However, higher MM was associated with a improved 5-year OS rate. Factors such as age, stage, grade, and surgery were also associated to OS rates. These findings suggest that higher muscle mass may lead to better outcomes for CRC patients, highlighting the potential impact of exercise and nutritional interventions on patient outcomes.

The preoperative scoring system combining neutrophil/lymphocyte ratio and CA19-9 predicts the long-term prognosis of intrahepatic cholangiocarcinoma patients undergoing curative liver resection

BackgroundThis study aims to investigate preoperative prognostic factors available for intrahepatic cholangiocarcinoma (ICC) patients and propose a new preoperative prognostic scoring system for ICC that combines CA19-9 and neutrophil/lymphocyte ratio (NLR).MethodsIn this retrospective analysis, 1728 patients diagnosed with ICC and undergoing curative liver resections were studied. This study employed univariate and multivariate Cox regression to find factors affecting recurrence and overall survival (OS), and furthermore assessed how preoperative models influenced tumor traits and postoperative recurrence.ResultsThe results of the multivariate Cox regression analysis indicated that two preoperative variables, NLR and Ca19-9, were independent risk factors affecting postoperative recurrence and OS in ICC patients. Based on this data, assigning a score of 0 (NLR ≤ 2.4 and Ca19-9 ≤ 37U/ml) or 1 (NLR > 2.4 and Ca19-9 > 37U/ml) to these two factors, a preoperative prognostic score was derived. According to the scoring model, patients were divided into three groups: 0 points (low-risk group), 1 point (intermediate-risk group), and 2 points (high-risk group). The 5-year recurrence and OS rates for the three groups were 56.6%, 68.2%, 77.8%, and 56.8%, 40.6%, 27.6%, respectively, with all P values < 0.001. Furthermore, high-risk group patients were more prone to early recurrence (early recurrence rates for high-, intermediate-, and low-risk groups were 56.8%, 51.5%, and 37.1%, respectively, P < 0.001) and extrahepatic metastasis (extrahepatic metastasis rates for high-, intermediate-, and low-risk groups were 31.7%, 26.4%, and 15.4%, respectively, P < 0.001). In terms of tumor characteristics, high-risk group patients had larger tumor diameters and were more likely to experience microvascular invasion, lymph node metastasis, and perineural invasion.ConclusionsThe predictive capacity of postoperative recurrence and OS rates in ICC patients is effectively captured by the preoperative scoring system incorporating NLR and CA19-9 levels.

Integrating Mcm-2 and Ki-67 immunohistochemistry with clinico-pathologic parameters for enhanced prognostic accuracy in oral verrucous lesions

BackgroundOral verrucous lesions (OVLs) present a diagnostic challenge due to their diverse and often confusing histopathological features. Accurate differentiation is essential for improving diagnosis and predicting prognosis. In addition to assessing overall survival (OS) and disease-free survival (DFS) in verrucous squamous cell carcinoma (VSCC) and conventional OSCC, this study seeks to evaluate the expression of Mcm-2 and Ki-67 in verrucous lesions and oral squamous cell carcinoma (OSCC). These findings will be correlated with the nuclear expression of Mcm-2 and Ki-67. MethodologyNinety tissue samples that were paraffin embedded and formalin-fixed were examined using immunohistochemistry to determine the expression of Mcm-2 and Ki-67. Data on survival and clinico-pathologic characteristics were taken from patient records. Statistical analyses were conducted using Independent T-tests, Cox regression models, and Kaplan-Meier survival analysis. ResultsMcm-2 was identified as a more sensitive and prognostic marker compared to Ki-67 across the study groups. Mcm-2 overexpression was observed in all cases of verrucous hyperplasia with dysplasia, verrucous carcinoma (VC), VSCC, and conventional OSCC. The 3-year OS and DFS rates were lower in conventional OSCC (75 % and 64.3 %, respectively) compared to VSCC (90 % and 70 %). ConclusionThis study represents the first initiative to employ both Mcm-2 and Ki-67 as proliferative markers for distinguishing between various oral verrucous lesions. Mcm-2 proves to be a valuable marker for differentiating between potentially malignant and malignant verrucous lesions. However, further validation with larger sample sizes and longer follow-up periods is necessary to confirm its role in predicting OS and DFS.

Perioperative toripalimab plus neoadjuvant chemotherapy might improve outcomes in resectable esophageal cancer: an interim analysis of a phase III randomized clinical trial.

In the era of immunotherapy, neoadjuvant immunochemotherapy (NAIC) for the treatment of locally advanced esophageal squamous cell carcinoma (ESCC) is used clinically but lacks of high-level clinical evidence. This study aimed to compare the safety and long-term efficacy of NAIC followed by minimally invasive esophagectomy (MIE) with those of neoadjuvant chemotherapy (NAC) followed by MIE. A prospective, single-center, open-label, randomized phase III clinical trial was conducted at Henan Cancer Hospital, Zhengzhou, China. Patients were randomly assigned to receive either neoadjuvant toripalimab (240 mg) plus paclitaxel (175 mg/m2) + cisplatin (75 mg/m2) (toripalimab group) or paclitaxel + cisplatin alone (chemotherapy group) every 3 weeks for 2 cycles. After surgery, the toripalimab group received toripalimab (240 mg every 3 weeks for up to 6 months). The primary endpoint was event-free survival (EFS). The pathological complete response (pCR) and overall survival (OS) were key secondary endpoints. Adverse events (AEs) and quality of life were also assessed. Between May 15, 2020 and August 13, 2021, 252 ESCC patients ranging from T1N1-3M0 to T2-3N0-3M0 were enrolled for interim analysis, with 127 in the toripalimab group and 125 in the chemotherapy group. The 1-year EFS rate was 77.9% in the toripalimab group compared to 64.3% in the chemotherapy group (hazard ratio [HR] = 0.62; 95% confidence interval [CI] = 0.39 to 1.00; P = 0.05). The 1-year OS rates were 94.1% and 83.0% in the toripalimab and chemotherapy groups, respectively (HR = 0.48; 95% CI = 0.24 to 0.97; P = 0.037). The patients in the toripalimab group had a higher pCR rate (18.6% vs. 4.6%; P = 0.001). The rates of postoperative Clavien-Dindo grade IIIb or higher morbidity were 9.8% in the toripalimab group and 6.8% in the chemotherapy group, with no significant difference observed (P = 0.460). The rates of grade 3 or 4 treatment-related AEs did not differ between the two groups (12.5% versus 12.4%). The interim results of this ongoing trial showed that in resectable ESCC, the addition of perioperative toripalimab to NAC is safe, may improve OS and might change the standard treatment in the future.

Real-World Analysis of Survival and Treatment Efficacy in Stage IIIA-N2 Non-Small Cell Lung Cancer.

Stage IIIA-N2 non-small cell lung cancer (NSCLC) poses a significant clinical challenge, with low survival rates despite advances in therapy. The lack of a standardised treatment approach complicates patient management. This study utilises real-world data from Guy's Thoracic Cancer Database to analyse patient outcomes, identify key predictors of overall survival (OS) and disease-free survival (DFS), and address the limitations of randomised controlled trials. This observational, single-centre, non-randomised study analysed 142 patients diagnosed with clinical and pathological T1/2 N2 NSCLC who received curative treatment from 2015 to 2021. Patients were categorised into three groups: Group A (30 patients) underwent surgery for clinical N2 disease, Group B (54 patients) had unsuspected N2 disease discovered during surgery, and Group C (58 patients) received radical chemoradiation or radiotherapy alone (CRT/RT) for clinical N2 disease. Data on demographics, treatment types, recurrence, and survival rates were analysed. The median OS for the cohort was 31 months, with 2-year and 5-year OS rates of 60% and 30%, respectively. Group A had a median OS of 32 months, Group B 36 months, and Group C 25 months. The median DFS was 18 months overall, with Group A at 16 months, Group B at 22 months, and Group C at 17 months. Significant predictors of OS included ECOG performance status, lymphovascular invasion, and histology. No significant differences in OS were found between treatment groups (p = 0.99). This study highlights the complexity and diversity of Stage IIIA-N2 NSCLC, with no single superior treatment strategy identified. The findings underscore the necessity for personalised treatment approaches and multidisciplinary decision-making. Future research should focus on integrating newer therapeutic modalities and conducting multi-centre trials to refine treatment strategies. Collaboration and ongoing data collection are crucial for improving personalised treatment plans and survival outcomes for Stage IIIA-N2 NSCLC patients.

Long-term results of induction chemotherapy for non-operable esophageal squamous cell carcinoma followed by concurrent chemoradiotherapy: a single-centre experience.

This study aimed to investigate the long-term clinical outcomes and toxicities of induction chemotherapy (IC) followed by concurrent chemoradiotherapy (CCRT) vs. CCRT alone in patients with non-operable esophageal squamous cell carcinoma (ESCC). Between 2008 and 2022, 271 ESCC patients who received definitive CCRT based on intensity modulated radiation therapy (IMRT)/volumetric modulated arc therapy (VMAT) were enrolled. Through a propensity score-matched (PSM) method, 71 patients receiving IC and CCRT were matched 1:1 to patients who received CCRT alone. The Kaplan-Meier method and Cox proportional hazards model were applied to analyze survival and prognosis. The IC + CCRT group had no improvement in 5-year overall survival (OS) rate, recurrence-free survival (RFS) rate, and distant metastasis-free survival (DMFS) rate (all p > 0.05) compared with the CCRT group. The 5-year OS rate (65.6% vs. 17.6% vs. 29.3%, p < 0.001), RFS rate (65.6% vs. 17.6% vs. 26.9%, p < 0.001), and DMFS rate (62.5% vs. 10.3% vs. 27.2%, p < 0.001) of the IC good responders were significantly higher than that of the IC poor responders and CCRT group. Multivariate analysis revealed that total radiotherapy time (≥ 49 days) and stage III/IV were independent predictive factors of OS, RFS, and DMFS. No significant differences were observed in the rates of grade 3-4 toxicities between both groups. Our results showed the addition of IC to CCRT was not superior to CCRT in unselected ESCC patients, while IC responders could benefit from this regime without an increase in toxicities.

Weekly Image Guidance in Patients With Cervical Cancer Treated With Intensity-Modulated Radiation Therapy: Results of a Large Cohort Study.

Image guidance is recommended for patients undergoing intensity-modulated radiation therapy (IMRT) for cervical cancer. In this study, we evaluated the feasibility of a weekly image guidance pattern and analyzed the long-term outcomes in a large cohort of patients. The study enrolled patients with Stage IB-IVA cervical cancer who received definitive radiotherapy or concurrent chemoradiotherapy. IMRT was delivered at a dose of 50.4 Gy in 28 fractions, with weekly cone-beam computed tomography (CBCT). Physicians advised patients on rectum and bladder preparation to help them prepare on nonimaging guidance days. When significant tumor regression was observed, a second computed tomography simulation and replanning were performed. The median follow-up periods were 63.4 months. The incidence rates of loco-regional and distant failure were 9.9% and 13.6%. The 5-year overall survival (OS), disease-free survival (DFS), loco-regional relapse-free survival (LRFS), and distant metastasis-free survival (DMFS) rates were 80.1%, 72.9%, 78.3%, and 74.8%, respectively. For patients with different stages, the 5-year OS, DFS, LRFS, and DMFS rates were statistically significant. For patients with and without positive regional lymph nodes, the 5-year OS, DFS, LRFS, and DMFS rates were 64.5% and 86.0%, 56.8% and 78.8%, 62.7% and 84.3%, and 58.8% and 81.0%, respectively. Multivariate analysis showed that age, histology, tumor size, cancer stage, pretreatment squamous cell carcinoma antigen level, and para-aortic metastatic lymph nodes were independent prognostic factors of OS. Fifty-six (4.0%) patients experienced late Grade 3/4 chronic toxicities. IMRT with weekly CBCT is an acceptable image guidance strategy in countries with limited medical resources.

Long-term survival and post-hoc analysis of toripalimab plus definitive chemoradiotherapy for oesophageal squamous cell carcinoma: insights from the EC-CRT-001 phase II trial

In the EC-CRT-001 phase II study, the combination of toripalimab (an anti-programmed death-1 antibody) and definitive chemoradiotherapy (CRT) has shown promising efficacy in patients with locally advanced oesophageal squamous cell carcinoma (ESCC). Here, we reported the long-term outcomes and post-hoc exploratory analyses. This single-arm, phase II trial enrolled 42 patients diagnosed with unresectable stage I-IVA ESCC was conducted at Sun Yat-sen University Cancer Center between November 2019 and January 2021. Treatment consisted of chemotherapy (weekly 50mg/m2 of paclitaxel and 25mg/m2 of cisplatin for five cycles), concurrent radiotherapy (50.4Gy in 28 fractions), and toripalimab (240mg every 3 weeks for up to 1 year). The primary endpoint was clinical complete response (CR) rate at 3 months after CRT completion. The 3-year overall survival (OS) and progression-free survival (PFS) rates were evaluated. Additionally, the exploratory objectives included analysing recurrence patterns, assessing the associations between immune-related adverse events (irAEs) and efficacy, and identifying potential predictors for irAEs. The trial was registered with ClinicalTrials.gov (NCT04005170). With a median follow-up of 44.3 months (IQR 40.8-46.1), the 3-year OS and PFS rates were 44.8% (95% CI 31.9-62.8) and 35.7% (95% CI 23.8-53.6), respectively. Patients who failed to achieve a clinical complete response (CR) demonstrated significantly worse OS (hazard ratio [HR]=13.73, 95% CI 4.43-42.54, P<0.0001) and PFS (HR=32.08, 95% CI 8.57-120.10, P<0.0001). Disease recurrence occurred in 23 of 42 patients (55%), with recurrences being earlier and more frequent in the non-CR group compared to the CR group. Patients experiencing irAEs showed a significantly higher CR rate (72% vs. 39%, P=0.082) and better PFS (HR=0.43, 95% CI 0.19-0.93, P=0.027) than those without irAEs. GON4L mutation was associated with a lower incidence of irAEs (P=0.036). The updated survival outcomes confirmed the efficacy of toripalimab plus definitive CRT in locally advanced ESCC. Moreover, the development of irAEs may predict a more favourable prognosis.

Cost-Utility Analysis of Stereotactic Body Radiation Therapy Versus Surgery for Patients With Stage I Non-small Cell Lung Cancer in Japan.

Stereotactic body radiation therapy (SBRT) for patients with operable stage I non-small cell lung cancer (NSCLC) is less invasive than surgery. However, differences in lifetime costs and patient outcomes remain unclear. In this study, a cost-utility analysis of SBRT compared with surgery for Japanese patients with operable stage I NSCLC was conducted. A partitioned survival model was constructed using each treatment arm's overall survival (OS) and progression-free survival (PFS) data. The data for the SBRT arm were extracted from the Japanese multicenter cohort study, which enrolled 678 medically operable patients with stage I NSCLC, and patient registry data were used for the surgery arm. The 5-year OS rate was 78.2% for SBRT and 74.8% for surgery from both studies. The 5-year PFS rate was 57.0% for SBRT and 63.4% for surgery. The quality of life values of PFS and progressive disease were obtained from domestic and overseas literature (PFS: 0.74, progressive disease: 0.65). The time horizon was set to 10 years. The expected costs and quality-adjusted life years for each treatment group were calculated. All costs are expressed in Japanese yen converted to US dollars (USD). SBRT was the dominant strategy, reducing treatment costs by 4,443.8 USD and increasing quality-adjusted life years by 0.131 compared with surgery. According to probabilistic sensitivity analysis, the probability of SBRT being dominant and cost-effective was 50.6% and 72.4%, respectively. Under the budget impact analysis, the total savings for the patients with stage I NSCLC in Japan was 6,252,870.0 USD (n = 1,407). SBRT is a more cost-effective option than surgery in patients with medically operable stage I NSCLC in Japan. Large-scale epidemiologic studies that reflect the latest clinical realities, such as OS/PFS, will be needed to validate this study's robustness.

Comparison of the Effectiveness of Transarterial Bland Embolization and Transarterial Chemoembolization for Intermediate-Stage Hepatocellular Carcinoma: A Propensity Score–Matched Study of 1,008 Patients

PurposeTo assess the effectiveness of transarterial bland embolization (TAE) compared with transarterial chemoembolization (TACE) therapy in the treatment of patients with intermediate-stage hepatocellular carcinoma (HCC). Materials and MethodsTwo thousand two hundred ninety-seven patients with intermediate-stage HCC were screened, and 1,461 patients who underwent TAE or TACE as the first-choice treatment were retrospectively analyzed and baseline matched according to the 2 treatment methods. Subgroup analysis was performed among patients according to the Up-to-7 criteria. The primary endpoint was overall survival (OS). ResultsA total of 1,461 patients with HCC who underwent TAE or TACE were included; 730 patients underwent TACE and 731 underwent TAE. The patients in the TAE group exhibited poorer liver function and a significantly higher rate of hepatitis B infection (P < .001) compared with the TACE group. After propensity score matching, 504 well-matched pairs of patients with intermediate-stage HCC were selected for analysis. Univariate analysis showed that TACE significantly prolonged patient survival compared with TAE (P < .001). The 1-, 2-, and 3-year OS rates were 74.3%, 57.1%, and 44.4% and for the TACE group and 58.3%, 32.4%, and 21.7% for the TAE group, respectively. Multivariate analysis showed a hazard ratio of 0.517 (95% CI, 0.442–0.605; P < .001) for the TACE approach over the TAE approach for OS. The TACE group had a significantly higher overall response rate than the TAE group (35% vs 26%; P = .024). ConclusionsTACE resulted in higher response rate and longer OS compared with TAE as the initial treatment for intermediate-stage HCC.

3D-printed individual template brachytherapy for the treatment of intractable central pelvic recurrent cervical cancer: A single institution experience

OBJECTIVEThe prognosis of recurrent cervical cancer tends to be poor and there are limited effective treatments currently available for these patients. This study was developed to find a safe and effective treatment for patients with central pelvic recurrent cervical cancer. MATERIALS AND METHODSThis retrospective study analyzed patients with central pelvic recurrent cervical cancer who received 3D-printed individual template (3D-PIT) brachytherapy between February 2019 and June 2023. Analyses of dosimetric parameters, toxicity-related complications, and survival were conducted based on the data of these patients. RESULTSTwenty-one patients with central pelvic recurrent cervical cancer patients were enrolled. All of them received 3D-printed individual template (3D-PIT) brachytherapy. The mean respective adjusted cumulative HRCTV-D90 and HRCTV-D98 values for these patients were 86.9 Gy and 75.4 Gy. And the local control (LC) rate of these patients was 57.1%. In these 21 patients, only 2 (9.5%) of them experienced grade 3–4 rectal adverse reactions, while 7 (33.3%) patients experienced grade 3–4 bladder adverse reactions. 5(23.8%) patients had fistula, while 3 of these 5 patients had undergone prior anti-VEGF targeted drug treatment which is a risk factor of fistula. The respective 2-year rates of overall and progression-free survival (OS and PFS) for these patients were 72.9% and 57.4%, with a 26-month median PFS. CONCLUSIONSThese single-institution data highlight the potential viability of 3D-PIT brachytherapy as an approach to managing intractable central pelvic recurrent cervical cancer following first-line treatment.

Safety, effectiveness and the optimal duration of preoperative imatinib in locally advanced gastric gastrointestinal stromal tumors: A retrospective cohort study.

The optimal duration of preoperative imatinib (IM) remains controversial. This study aimed to evaluate the safety, therapeutic effectiveness, and optimal duration of preoperative IM in patients with locally advanced gastric gastrointestinal stromal tumors (GIST). The clinicopathologic data of 41 patients with locally advanced gastric GIST who received preoperative IM and underwent surgical resection from January 2014 and December 2021 were retrospectively analyzed. After a median of 7.0 (IQR: 4.5-10) months of preoperative IM treatment, 30 patients experienced adverse events (AEs), 80% of which were grade 1/2 AEs. The mean tumor size decreased from 12.71 ± 5.34 cm to 8.26 ± 4.00 cm, with a reduction rate of 35%. Setting 8 months as the cut-off value according to the results of ROC analysis. The proportion of laparoscopic surgery was higher in patients with short-term (≤8 months) versus long-term (>8 months) preoperative IM. Compared with the subtotal/total gastrectomy group, patients in the local gastrectomy group exhibited less intraoperative blood loss, shorter length of postoperative hospital stay, and fewer postoperative complications. The 3-year recurrence-free survival (RFS) and overall survival (OS) rates were 82.9% and 97.6%, and the expected 5-year RFS and OS rates were 75.6% and 90.2% respectively. RFS was better in the short-term than in the long-term preoperative IM treatment group, and it was also better in pre- plus postoperative IM treatment group than that in the preoperative IM alone group. Both univariate and multivariate COX analysis showed that a higher mitotic index and long-term preoperative IM treatment were associated with worse RFS, while postoperative IM treatment could significantly improve RFS. The study suggests that in patients with locally advanced gastric GIST, preoperative short-term (≤8 months) use of IM is associated with higher RFS than long-term use.

Risk Stratification According to Baseline and Early Change in Neutrophil-to-Lymphocyte Ratio in Advanced Non-Small Cell Lung Cancer Treated with Chemoimmunotherapy: A Multicenter Real-World Study.

Chemoimmunotherapy is a standard treatment for advanced non-small-cell lung cancer (NSCLC). However, data on clinical predictive factors remain scarce. We aim to identify clinical biomarkers in patients undergoing chemoimmunotherapy. This multicenter, real-world cohort study included chemonaive patients who underwent chemoimmunotherapy between December 2018 and May 2022. Multivariate analysis was used to determine associations between survival outcomes and patient background, including baseline neutrophil-to-lymphocyte ratio (NLR) and its dynamic change (ΔNLR). To further investigate the clinical significance of NLR, patients were classified based on their peripheral immune status, defined by a combination of NLR and ΔNLR. The study included 280 patients with 30.1 months of median follow-up. Multivariate analysis revealed that older individuals, poor performance status, tumor proportion score < 1%, liver metastasis, baseline NLR ≥ 5, and ΔNLR ≥ 0 independently correlated significantly with shorter progression-free and overall survival (OS). Patients with high peripheral immune status (defined as NLR <5 and ΔNLR < 0) significantly improved long-term survival (2-year OS rate of 58.3%), whereas those with low peripheral immune status (defined as NLR ≥ 5 and ΔNLR ≥ 0) had extremely poor outcomes (2-year OS rate of 5.6%). Safety profiles did not differ significantly in terms of severe adverse events and treatment-related death rates despite the patients' peripheral immune status (P = 0.46 and 0.63, respectively). Our study provides real-world evidence regarding clinical prognostic factors for the efficacy of chemoimmunotherapy. The combined assessment of baseline NLR and ΔNLR could facilitate the identification of patients who are likely to achieve a durable response from chemoimmunotherapy.

The benefit of adjuvant chemotherapy in pathological T1-3N0M0 rectal mucinous adenocarcinoma: no improvement survival outcomes based on long-term survival analysis of large population data.

Currently, the benefits of the administration of adjuvant chemotherapy (AT) in pathological low-risk rectal mucinous adenocarcinoma (RM) with T1-3N0M0 are unclear. The objective of this study is to retrospectively investigate the clinical significance of AT in terms of survival outcomes for patients with pathological T1-3N0M0 RM using data from a large population. The patient data were collected from the Surveillance, Epidemiology, and End Results (SEER) Program. The Chi-squared test was used to analyze categorical variables. The survival curves were compared using the log-rank test and the Kaplan-Meier method. A multivariate proportional hazards regression (Cox) model was applied to identify the independent prognostic factors of survival outcomes. Propensity score matching (PSM) was utilized to eliminate the differences between groups and estimate AT's effect. The median follow-up duration for the rectal cancer (RC) cohort was 116 months. Multivariate analyses revealed that RM was a significant adverse prognostic factor, correlating with poorer overall survival (OS) and cancer-specific survival (CSS) for RC [hazard ratio (HR): 1.226, 95% confidence interval (CI): 1.094-1.375, P<0.001; HR: 1.446, 95% CI: 1.242-1.683, P<0.001]. Among patients with RM, the rates of 5-year OS and CSS were 68.6% and 79.3% in the AT (-) group, respectively. Additionally, the AT (+) group exhibited similar rates of 65.6% for 5-year OS and 74% for CSS (P=0.80, P=0.26). Subtype analysis according to preoperative therapy status showed that AT also did not significantly affect survival outcomes (P=0.65, P=0.34; P=0.90, P=0.76). Our study found that RM is a poor prognostic factor in pathological T1-3N0M0 RC. However, AT does not appear necessary to improve survival outcomes of pathological T1-3N0M0 RM.

Neoadjuvant camrelizumab followed by concurrent camrelizumab plus chemotherapy for locally advanced esophageal squamous cell carcinoma: a single-arm, phase II study.

Neoadjuvant therapy combining camrelizumab with chemotherapy has emerged as a promising approach for treating locally advanced esophageal squamous cell carcinoma (ESCC). However, the optimal strategy for integrating immunotherapy with chemotherapy remains to be fully defined. This single-arm phase II study aimed to evaluate the efficacy and safety of neoadjuvant therapy with camrelizumab induction followed by camrelizumab plus chemotherapy in locally advanced ESCC. Patients with clinical stage cT2-4N0M0 or cTxN1-3M0 ESCC were enrolled in the study. Patients received one dose of camrelizumab (200 mg) followed by docetaxel (75 mg/m2) and nedaplatin (75 mg/m2) plus camrelizumab (200 mg) every 3 weeks for two cycles, and then underwent surgery within 3-4 weeks. The primary endpoint was the major pathological response (MPR) rate. The secondary endpoints included the pathological complete response (pCR) rate, R0 resection rate, downstaging rate, disease-free survival (DFS), overall survival (OS), and safety. In total, 55 patients were enrolled in the study between 16 April 2020 and 30 October 2021. Of these 55 patients, 53 (96.4%) completed neoadjuvant therapy, and 48 (87.3%) underwent surgery. The MPR rate was 77.1% [37/48, 95% confidence interval (CI): 62.7-88.0%]. The pCR (ypT0N0) rate was 39.6% (19/48, 95% CI: 25.8-54.7%). All the patients had R0 resections. Primary tumor downstaging occurred in 44 (91.7%) patients, and nodal downstaging occurred in 19 (39.6%) patients. The 2-year DFS rate was 68.9% (95% CI: 53.0-80.4%), and the 2-year OS rate was 74.7% (95% CI: 60.2-84.6%). Grade ≥3 treatment-related adverse events (TRAEs) were observed in 7 (12.7%) patients. In conclusion, neoadjuvant camrelizumab followed by camrelizumab plus chemotherapy showed promising efficacy in treating locally advanced ESCC and had a manageable safety profile.

Effectiveness of multi-disciplinary team management on 5-year overall survival for patients with stage III lung cancer.

Stage III lung cancer (LC) represents a heterogeneous group of diseases, and the optimal management is still a matter of debate. To date, only a few studies have assessed the role of multidisciplinary team (MDT) discussion in impacting survival of stage III LC. Hence, we aimed to reported the impact of the implementation of MDT discussion on long-term survival of stage III LC patients. This is a retrospective, observational, single-centre cohort study evaluating data of consecutive patients with a clinical and pathological diagnosis of stage III LC treated before [2005-2011] and after [2012-2020] the implementation of MDT. The primary outcome was 5-year overall survival (OS). A total of 983 patients were enrolled with stage III LC, 411 (41.8%) pre-MDT and 572 (58.2%) post-MDT. The 5-year OS rates were 25.3% for the pre-MDT cohort and 33.9% for the post-MDT cohort (P=0.0008). Resected patients (n=670), who underwent trimodality therapy achieved a higher 5-year OS in both pre-MDT and post-MDT groups. An increased 5-year OS was observed in patients who underwent systemic therapy, from 28.2% in pre-MDT to 40.2% in post-MDT cohorts. In non-resected patients, there was an increased in 5-year OS in both systemic and chemoradiotherapy groups. The implementation of an MDT increased the 5-year OS in both resected and non-resected stage III LC patients. Implementing MDT might be useful in improving the management of therapy with less invasive local and surgical strategies personalized for each LC patient.

Differential effect of tumor budding on the benefit of adjuvant chemotherapy in stage II colorectal cancer: a retrospective observational study.

Tumor budding (TB) has been shown to be a poor prognostic indicator after colorectal cancer (CRC) surgery. The aim of the present study is to evaluate the predictive role of morphological features (e.g., the number, structure, and location of tumor buds, and their reaction with the extracellular mesenchyme) in postoperative adjuvant chemotherapy in surgically resectable stage II CRC. Between 2016 and 2019, 336 patients with stage II CRC who underwent radical surgery were enrolled in this study. TB status was determined according to the criteria adopted at the 2016 International Tumor Budding Consensus Conference (ITBCC). We retrospectively recorded all the clinical and pathological data and assessed the effect of different types of TB status on patients' recurrence-free survival (RFS) and overall survival (OS). Of the 336 patients, 173, 88, and 75 were budding grade 1 (BD1), BD2, and BD3, respectively. The 5-year RFS rates were 84.6%, 81.2%, and 68.0% (P=0.01), and the 5-year OS rates were 91.0%, 83.3%, and 76.2% (P=0.007) in BD1, BD2, and BD3, respectively. TB grade was strongly associated with vascular invasion status and mucinous adenocarcinoma, and BD3 was detected in 51.7% of patients with positive vascular invasion. The multivariate analysis showed that only age, perineural invasion, and TB grade [BD2 vs. BD1, hazard ratio (HR) =1.468, 95% confidence interval (CI): 0.703-3.063, P=0.30; BD3 vs. BD1, HR =2.310, 95% CI: 1.154-4.625, P=0.01] had an independent effect on RFS. In addition, the Kaplan-Meier curve analysis showed that BD3 patients had the worst RFS (P=0.01). The OS of the adjuvant chemotherapy group was significantly improved compared to that of the surgery-only group in the BD1/2 patients (HR =0.278, 95% CI: 0.114-0.676, P=0.005) but not in the BD3 patients with significant interaction (Pinteraction=0.03). Our results indicate that TB could play a subsidiary role in selecting stage II CRC patients who could achieve a favorable prognosis with chemotherapy.

Long-term outcomes of laparoscopic versus open total gastrectomy in patients with advanced gastric cancer after neoadjuvant chemotherapy: a retrospective cohort study

BackgroundThis study was conducted to investigate the long-term outcomes of laparoscopic total gastrectomy (LTG) versus open total gastrectomy (OTG) in patients with advanced gastric cancer (AGC) after neoadjuvant chemotherapy (NACT).MethodsPatients with AGC who received NACT before surgery were enrolled in either the LTG or OTG group. Propensity score matching (PSM) (1:2) was performed between the two groups based on the propensity score using a 0.15 calliper width. Three-year overall survival (OS) and disease-free survival (DFS) were compared between these two groups before and after PSM. OS and DFS rates were calculated by the Kaplan‒Meier method, and any differences in survival were evaluated with a log-rank test. Univariate and multivariate Cox proportional hazards analyses were used to estimate the simultaneous effects of prognostic factors on survival and the hazard ratio (HR) between LTG and OTG patients.ResultsA total of 144 patients completed the follow-up, with 24 patients in the LTG group and 120 patients in the OTG group. After a mean follow-up of 64.40 months, there were no significant differences in the 3-year OS or DFS rates between the two groups before (P = 0.453 and P = 0.362, respectively) or after PSM (P = 0.972 and P = 0.884, respectively). Multivariate Cox proportional hazards analysis indicated that ypN stage was an independent risk factor for worse OS (P = 0.013).ConclusionsThis study showed that LTG with D2 lymphadenectomy performed by an experienced surgical team resulted in comparable 3-year OS and DFS compared with OTG in patients with AGC after NACT.Trial registrationThis study is not registered.

Radiotherapy with S-1 for the treatment of esophageal squamous cell carcinoma 75 years or older

ObjectiveExplore the efficacy and safety of involved-field irradiation (IFI) combined with S-1 as definitive concurrent chemoradiotherapy (dCRT) for locally advanced elderly esophageal squamous cell carcinoma (ESCC), under the premise of intensity-modulated radiotherapy (IMRT).MethodsWe designed a prospective single-arm phase II study. The study enrolled 91 patients aged 75 to 92 years. Eligible participants had histologically confirmed squamous cell carcinoma, stage II to IV disease based on the 8th edition of the American Joint Committee on Cancer (AJCC). All elderly patients (EPs) received dCRT with S-1. which was administered orally twice daily for 28 days. The radiotherapy dose was 61.2 Gy delivered in 34 fractions or 50.4 Gy delivered in 28 fractions. The primary endpoint was 2-year overall survival (OS), and the secondary endpoints were progression-free survival (PFS), local control rate (LCR), and safety.ResultsFrom July 2017 to July 2021, we enrolled EPs with ESCC who were treated at the Jiangsu Cancer hospital. As of August 1, 2023, the median follow-up of surviving EPs was 31.4 months (IQR: 25.2 to 72.6 months). 83 patients (91.2%) completed the whole course of treatment. The 2-year OS rate was 59.2%, and the PFS rate was 43.7%. The most common grade 1 to 2 adverse effects (AEs) were radiation esophagitis (79.1%), and then were radiation pneumonia (46.2%). Anemia (41.8%) was the most common of grade 1 to 2 hematologic toxicity. The incidence of grade 3 or above AEs was 24.2%, and the incidence of leukopenia was the highest (11.0%). There was not one death due to treatment-related toxicity. In a subgroup analysis of radiotherapy doses, we found no statistically significant differences in PFS (P = 0.465) and OS (P = 0.345) in EPs with ESCC who received 50.4 Gy and 61.2 Gy, and that patients in the 50.4 Gy group had lower dermatitis (P = 0.045) and anemia (P = 0.004).ConclusionsIF-IMRT combined with S-1 is a promising regimen for elderly ESCC. And the radiotherapy dose of 50.4 Gy remains the standard dose for EPs with ESCC undergoing CCRT.

Effect of Nivolumab on the Quality of Life in Recurrent/Metastatic Head and Neck Cancer.

Nivolumab is expected to further prolong survival and improve the quality of life (QOL) of patients with a poor prognosis of head and neck cancer. However, only a few studies have been conducted regarding the QOL of recurrent or metastatic head and neck cancer patients treated with nivolumab using real-world data. This study aimed to examine the effect of nivolumab on the QOL of these patients using real-world data. This study included patients with recurrent metastatic head and neck cancer who received nivolumab at the Department of Otolaryngology and Head and Neck Surgery, Tokyo Medical University Hospital from May 1, 2017, to December 31, 2021. Among them, 50 patients who self-assessed their QOL were included in this study. The primary endpoint was the QOL evaluation score, and secondary endpoints were overall survival (OS), progression-free survival (PFS), response rate, and immune-related adverse events. OS and PFS were evaluated using the Kaplan-Meier method. No significant reduction in QOL was observed before or after nivolumab administration. The median OS time was 20.1 months, and 1-year OS rate was 76.4%. The median PFS time was 4.2 months, and 1-year PFS rate was 31.0%. The comparison of patient QOL before and after nivolumab use suggested that patient QOL was not compromised. The results were not inferior to those of other studies in terms of treatment efficacy and safety.
