Background: Unlike developed countries where studies on all aspects of colorectal cancers are widely numerous, Iran as a Middle Eastern country show very few studies especially ones comparing the differences between colon and rectal cancer. In this study, firstly we report demographic, clinical and pathologic characteristics of patients with rectum and colon cancer and secondly compare these findings in order to investigate probable differences.
Methods: In this cross-sectional study, 238 patients were divided into two groups: the rectal cancer group and the colonic cancer group. Demographic, clinical and pathologic information of patients were statistically compared using Stata version 12.
Results: There were no statistical differences between the two groups regarding age and gender and BMI. Regarding clinical presentation, the proportion of rectal bleeding was significantly higher in colon cancer group (P<0.001). Moreover, abdominal pain was significantly more frequent in colon cancer group (P<0.001). Tumor stage showed statistically difference between the two groups (P=0.02).
Conclusions: We did not find enough evidences to conclude that rectal cancer and colon cancer should be investigated as two distinct malignancies but findings showed significant differences such as stage at diagnosis encouraged us in order to conduct other appropriate studies for better evaluation of this issue.

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.

The surgical risk is higher for obese patients undergoing laparoscopic left hemicolectomy. To enhance the surgical safety and efficacy for obese patients, we have innovatively integrated the advantages of various surgical approaches to modify a pancreas-guided C-shaped surgical procedure. The safety and quality were assessed through a retrospective analysis.

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.

Aberrant sialylated glycosylation in the tumor microenvironment is a novel immune suppression pathway, which has garnered significant attention as a targetable glycoimmune checkpoint for cancer immunotherapy to address the dilemma of existing therapies. However, rational drug design and in-depth mechanistic studies are urgently required for tumor sialic acid to become valuable glycoimmune targets. In this study, we explored the positive correlation of PD-L1 and sialyltransferase expression in clinical colorectal cancer tissues and identified their mutual regulation effects in macrophages.
