Background: Incomplete mesorectal excision during rectal cancer surgery often leads to positive circumferential margins, with uncertain prognostic impacts. This study examines whether negative margins can mitigate the poorer prognosis typically associated with incomplete total mesorectal excision (TME) in rectal cancer surgery, thus potentially challenging the prevailing emphasis on complete mesorectal excision.
Patients And Methods: A retrospective analysis was conducted on patients who underwent proctectomy for rectal adenocarcinoma with incomplete TME at a single center from 2010 to 2022.

Background: While hepatocellular carcinoma (HCC) remains the leading cause of liver transplant (LT) for liver tumors, indications have broadened over the years. Data regarding patient characteristics and outcomes of LT for liver tumors are limited.
Methods: From Jan-2002 to March-2022, 14,406 LT recipients for various liver tumors were identified in United Network for Organ Sharing database.

Aims: Medullary carcinoma of the colon is a rare subtype of adenocarcinoma, first described in 1999. Clinically known to have a favourable prognosis in comparison to poorly differentiated cancers, it is associated with deficient mismatch repair. This is an observational single center study of patients with medullary cancer, and comparison with the current literature.

Metabolite levels and turnover rates are necessary to understand metabolomic dynamics in a living organism fully. Amino acids can play distinct roles in various cellular processes, and their abnormal levels are associated with pathological conditions, including cancer. Therefore, their levels, especially turnover rates, may provide enormous information about a phenotype.
