Objective: To evaluate the efficacy of adjuvant cisplatin-based chemotherapy for locally advanced upper tract urothelial cell carcinoma (UTUC) following radical nephroureterectomy with bladder cuff resection (RNU) in terms of survival and recurrence.
Materials And Methods: Between January 2000 and January 2013, among 145 patients with upper tract urothelial cell carcinoma, a total of 65 patients with locally advanced UTUC (a diagnosis of pT3 or pT4 or pT1-2N1-3) underwent RNU. Of these 65 patients, 36 patients received at least three cycles of adjuvant gemcitabine plus cisplatin chemotherapy and the remaining 29 patient did not receive adjuvant chemotherapy. Clinical characteristics, bladder recurrence, distant metastasis, and cancer-specific survival were retrospectively reviewed.
Results: The mean age of the 65 patients was 60.4 (range, 37-87) years and the median follow-up period was 34 (range, 12-114) months. Patent demographics were not statistically different between the two groups. During the follow-up period, 14 patients (21.5%) experienced distant metastasis; 8 (8/36, 22.2%) patients who had undergone adjuvant chemotherapy and 6 (6/29, 20.7%) patients who did not. Bladder recurrence was noted in 17 patients (26.2%), 5 (5/36, 13.9%) of whom received adjuvant chemotherapy while the remaining 12 (12/29, 41.4%) did not. Kaplan-Meire and multivariate analysis showed that the incidence of bladder recurrence was significantly higher in patients who did not undergo adjuvant chemotherapy, and cancer specific survival was not significantly associated with adjuvant chemotherapy.
Conclusions: Adjuvant chemotherapy for locally advanced UTUC can prevent bladder recurrence, but has a minimal effect on cancer-specific survival.

Introduction: The standard of care for stage III colon cancer is 3 or 6 months of double-drug regimen chemotherapy following radical surgery. However, patients with positive circulating tumour DNA (ctDNA) exhibit a high risk of recurrence risk even if they receive standard adjuvant chemotherapy. The potential benefit of intensified adjuvant chemotherapy, oxaliplatin, irinotecan, leucovorin and fluoropyrimidine (FOLFOXIRI), for ctDNA-positive patients remains to be elucidated.

Cervical cancer is preventable with screening and vaccination approaches; however, access to these preventative measures is limited both nationally and globally and thus many women will still develop cervical cancer. Novel treatments and practice-changing research have improved cervical cancer outcomes over the past few decades. In this Review, we discuss clinical trials that have refined or redefined the treatment of cervical cancers across the early stage, locally advanced, persistent, recurrent and/or metastatic disease settings.

Purpose: The role of adjuvant chemotherapy in rectal cancer patients downstaged to ypT0-2 N0 after neoadjuvant chemoradiotherapy (CRT), and surgery is still debated. This study investigates the impact of adjuvant chemotherapy on survival outcomes in this patient population.
Methods: This retrospective study analyzed hospital records of rectal cancer cases from Shefa Al Orman Cancer Hospital between January 2016 and December 2020, focusing on patients downstaged to ypT0-2 N0 after neoadjuvant CRT and surgery.

Objective: The lack of consensus on the benefits and harms of standard therapies, including surgery (SRx), radiotherapy (RTx), chemotherapy (CTx), and their combinations among early-stage MCC, prompted this study.
Methods: A systematic review and meta-analysis of randomized and non-randomized studies published between January 01, 1972, and January 31, 2023, and having overall survival (OS), local recurrence (LR), regional recurrence (RR), disease-specific survival (DSS), and/or disease-free survival (DFS) as outcomes was conducted using the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed (NCBI), Scopus (ELSEVIER), and Web of Science (CLAVIRATE) databases. Hazard ratios (HRs) and their variances were pooled using the inverse variance heterogeneity model.
