Background: This study aimed to investigate the relationship between the ratio of negative lymph nodes (NLN) number to the number of metastatic lymph nodes (MLN) and the harvested lymph nodes (HLN) number ratio survival rate and compare its prognostic value.
Methods: This retrospective cohort study included 207 stage III colon cancer patients between 2010 and 2018 at a single center. NLN/MLN and NLN/HLN cut-off values were determined with the receiver operating characteristic (ROC) curve according to 5-year survival. The patients were divided into high-risk and low-risk groups according to the cut-off value. These 2 groups were evaluated according to the clinicopathological data of the patients.
Result: The time-dependent ROC curve showed the optimal cut-off values of NLN as 3.86 and .79, respectively. These values show 83 patients in the high-risk group and 124 in the low-risk group. There was no difference between the groups in tumor localization and T stage. According to Kaplan-Meier survival analysis, mean survival was 35.88 months in the high-risk group and 50.18 months in the low-risk group. The risk of death in the high-risk group was 305% compared to the low-risk group (Hazard Ratio: 3.05, 95% 1.91 - 4.88) ( < .001).
Conclusion: NLNs are among the critical prognostic factors in colon cancer. Although NLNs have a positive correlation with the survival rate of the patients, there is no statistical difference in tumor T stage and localization.

Background: Previous studies indicated that over-dissection of lymph nodes might impair the efficacy of immunotherapy. This study aims to explore the prognostic value of ypN + status and the impact of lymph node dissection (LND) on survival after neoadjuvant immunochemotherapy (NICT) for esophageal squamous cell cancer (ESCC).
Methods: This double-center retrospective study enrolled 206 consecutive ESCC patients who underwent NICT followed by esophagectomy between 2018 and 2024.

Background: Minimally invasive pancreaticoduodenectomy (MIPD) is used more commonly, but this surge is mostly based on observational data. This meta-analysis aimed to compare the short-term outcomes between MIPD and open pancreaticoduodenectomy (OPD) using data collected from randomized controlled trials (RCTs).
Methods: We searched PubMed, Cochrane Library, Embase, and Web of Science databases for RCTs comparing MIPD and OPD published before December 10, 2024.

Introduction And Aim: Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are rare neoplasms originating in neuroendocrine cells from the gastric mucosa and submucosa, small intestine, large intestine, rectum, and pancreas. Our aim was to describe their histopathologic, endoscopic, and clinical characteristics and the experience with these tumors at a tertiary care hospital center in the Colombian Southwest.
Materials And Methods: A retrospective, analytic, observational, and descriptive study included 93 patients diagnosed with GEP-NETs, within the time frame of 2018 and 2022.

Mesentery is a crucial part of an animal's digestive system since it holds the intestine in place, while also contains the specialized lymph nodes and immune cells that help protect the intestines from infections and support the body's immune response in the abdominal cavity. Analyzing mesenteric lymph can help better understand the transport mechanisms and potential implications for various conditions, such as lymphatic disorders or underlying infections. The first step towards this is the precise collection of the mesenteric lymph.

Background: To compare the short-term outcomes of robotic abdominoperineal resection with laparoscopic abdominoperineal resection in patients with rectal cancer.
Methods: We searched PubMed, Embase, and Cochrane through March 2024 following PRISMA guidelines (PROSPERO number: CRD42024520671). Randomized controlled trials and nonrandomized studies comparing short-term outcomes between the 2 approaches were selected.
