Background: A laparoscopic approach to right colectomies for emergency right colon cancers is under investigation. This study compares perioperative and oncological long-term outcomes of right colon cancers undergoing laparoscopic or open emergency resections and identifies risk factors for survival.
Methods: Patients were identified from a prospectively maintained institutional database between 2009 and 2019. Demographics, clinicopathological features, recurrence, and survival were investigated. Cox regression analysis was performed for risk factor analysis.
Results: A total of 202 right colectomies (114 open and 88 laparoscopic) were included. ASA III-IV was higher in the open group. The conversion rate was 14.8%. Laparoscopic surgery was significantly longer (156 vs. 203 min, < 0.001); pTNM staging did not differ. Laparoscopy was associated with higher lymph node yield, and showed better resection clearance (R0, 78.9 vs. 87.5%, = 0.049) and shorter postoperative stay (12.5 vs. 8.0 days, < 0.001). Complication rates and grade were similar. The median length of follow-up was significantly higher in the laparoscopic group (20.5 vs. 33.5 months, < 0.001). Recurrences were similar (34.2 vs. 36.4%). Open surgery had lower five-year overall survival (OS, 27.1 vs. 51.7%, = 0.001). Five-year disease-free survival was similar (DFS, 55.8 vs. 56.5%). Surgical approach, pN, pM, retrieved LNs, R stage, and complication severity were risk factors for OS upon multivariate analysis. Pathological N stage and R stage were risk factors for DFS upon multivariate analysis.
Conclusions: A laparoscopic approach to right colon cancers in an emergency setting is safe in terms of perioperative and long-term oncological outcomes. Randomized control trials are required to further investigate these results.

Background: Colon adenocarcinoma (COAD) is a leading cause of cancer-related mortality worldwide. Transient receptor potential vanilloid 4 (TRPV4), a calcium-permeable non-selective cation channel, has been implicated in various cancers, including COAD. This study investigates the role of TRPV4 in colon adenocarcinoma and elucidates its potential mechanism via the ferroptosis pathway.

Background/aim: The effectiveness of a transanal drainage tube (TAT) for the prevention of anastomotic leakage after double stapling technique (DST) anastomosis in colorectal cancer has been reported. Previously, TATs had been placed and connected to drainage bags. It was considered that a higher decompression effect could be expected by inserting an open-type TAT, without connection to a drainage bag.

Background: Aspirin is a simple, globally available medication that has been shown to reduce the incidence of colorectal cancer. We aimed to evaluate the safety and efficacy of aspirin in the secondary prevention of colorectal cancer.
Methods: This phase 3, randomised, double-blind, placebo-controlled trial was conducted at 66 centres across 11 countries and territories (ten in Asia-Pacific; one in the Middle East).

FBXW7 is a tumor suppressor gene that regulates metabolism and is associated with the onset and progression of colorectal cancer (CRC)), however, the precise mechanism whereby FBXW7 participates in the metabolic reprogramming of CRC remains unclear. Here, the research aims to reveal the association between the expression of FBXW7 and clinical variables and to investigate the molecular mechanism by which FBXW7 plays a critical role in the development of CRC. The clinical importance of FBXW7 in CRC was determined by immunohistochemistry.
