Objective: Currently, the correlation between preoperative bilirubin level and overall survival (OS) remains poorly defined in respectable perihilar cholangiocarcinoma (CC). The objectives of the current study were to evaluate the outcomes of perihilar CC after resection and then to analyze factors influencing curative resection, tumor recurrence and OS.
Methods: 115 patients with perihilar CC underwent surgical resection were retrospectively analyzed based on clinic characteristics, operative details, tumor recurrence and long-term survival data.
Results: The 1-, 3-, and 5-year OS rates after resection were 75.9%, 36.5%, 21.7%, whereas the corresponding tumor recurrence rates were 29.6%, 70.8%, 85.3%, respectively. Preoperative bilirubin level combined with liver resection, resection margin, vascular invasion and perineural invasion, lymph node metastasis and TNM stage were found to be correlated with OS and tumor recurrence. Multivariate analysis showed that preoperative bilirubin level together with resection margin, perineural invasion, and TNM stage were independent predictors of OS and tumor recurrence. Furthermore, preoperative bilirubin level was related with R0 resection, lymph node metastasis, TNM stage and postoperative liver function recovery.
Conclusion: Preoperative bilirubin level may effectively reflect the severity of perihilar CC and predict the OS and tumor recurrence after resection for perihilar CC patients.

Curative-Intended Management of Synchronous Esophageal and Rectal Cancer-A Systematic Literature Review.

Department of Radiotherapy and Radiation Oncology, Jena University Hospital, 07747, Jena, Germany.
Purpose: Synchronous esophageal (EC) and rectal carcinoma (RC) is a rare and challenging condition, particularly in curative-intended treatment. Especially locally advanced tumors may not be suitable for primary resection and require individual multimodal treatment. This review examines curative-intended management of synchronous EC and RC.

Background: Radiotherapy is the primary treatment modality for most head and neck cancers (HNCs). Despite the addition of chemotherapy to radiotherapy to enhance its tumoricidal effects, almost a third of HNC patients suffer from locoregional relapses. Salvage therapy options for such recurrences are limited and often suboptimal, partly owing to divergent tumor and microenvironmental factors underpinning radioresistance.

Background: Early identification of the risk of early cancer-related death (within one year, ECRD) due to recurrence after liver resection for hepatocellular carcinoma (HCC) patients with Barcelona Clinic Liver Cancer (BCLC) stage B/C is important for surgeons to make clinical decisions. Our study aimed to establish a nomogram to predict the ECRD due to recurrence for HCC patients with BCLC stage B/C.
Methods: A total of 672 HCC patients with BCLC stages B/C from four medical centers between January 2012 and December 2018 were included in our study.
Immediate second resection versus restage transurethral resection of bladder tumor: A prospective randomized clinical trial (IMMERSE trial).
Urol Oncol
January 2025
Department of Pathology, All India Institute of Medical Sciences, New Delhi, India.
Background: The role of repeat transurethral resection of bladder tumor (TURBT) for the management of nonmuscle invasive bladder carcinoma is debated, especially when initial resections include detrusor muscle. This study compares immediate second resection (additional deep biopsies in the same session) with standard restage TURBT performed 2-6 weeks post-initial TURBT to determine adequacy in detrusor muscle sampling and compare the disease rate at restage TURBT in both groups.
Material And Methods: A randomized trial was conducted at a tertiary care hospital, including patients aged ≥18 years undergoing TURBT with complete primary tumor resection.
Oncological Outcomes From Cytoreductive Surgery and Heated Intraperitoneal Chemotherapy for Colorectal Cancer Peritoneal Metastases.

Cytoreductive surgery (CRS) is effective for colorectal cancer peritoneal metastases (CRPM) at increasing overall survival (OS) compared to systemic anticancer treatment (SACT) alone. The addition of Oxaliplatin heated intraperitoneal chemotherapy (HIPEC) has been shown in a randomized controlled trial to result in increased complications without significant OS benefit. This study evaluates outcomes for CRPM patients undergoing CRS+HIPEC with Oxaliplatin (Ox) 368mg/m (30 min), versus Mitomycin C (MMC) 35mg/m (90min).
