Tumor size impact on TNM staging which define post-operative complications in rectal cancer

AbstractThe purpose of this study was to see how accurate tumor size was at predicting T and N stages in rectal malignancies. Tumor sizes of 40  mm and greater than 40 mm were used to assess post-operative challenges in related to T1–T2 and T3–T4 stages, as well as between node N0 and node N1 and N2 patients. A total of 131 patients were treated for colorectal cancer, with 54 patients <  40 mm and 77 patients >  40 mm receiving Da Vinci colorectal surgery. Conferring to the Clavien–Dindo classification grade III, there’s an increase in the percentage of tumors >  40 mm, which also impacts the percentage of intestinal obstruction, anastomotic leakage, GERD, and sepsis with aP <  0.05. A tumor size of more than 40 mm is strongly associated with advanced pT stages. Tumor size may serve in addition to clinical staging and improve the management of rectal cancer.
