Background And Objectives: It is unknown how patients with locally advanced rectal cancer with significant response to preoperative radiotherapy/chemoradiotherapy fare relative to patients with true pathologic 0-1 disease undergoing upfront surgery. We aimed to determine whether survival is improved in locally advanced rectal cancer downstaged to pathologic stage 0-1 disease compared to true pathologic stage 0-1 tumors.
Methods: A retrospective review of the National Cancer Database between 2004 and 2016 was conducted.
Background: The oncologic outcomes of right-sided cancers are generally grouped in studies. We hypothesized that tumor location (cecal vs. ascending vs.

Design: The National Cancer Database (2010-2015) was queried for all patients with malignant colonic polyps who underwent formal colonic resection. Univariate and multivariate methods were used to determine independent predictors of lymph node metastasis.
Background: Studies have reported worse overall survival (OS) for adenosquamous carcinoma (ASC) compared to adenocarcinoma (AC) of the colon, but none have analyzed a national dataset for over 30 years.
Methods: The National Cancer Database was queried from 2004 to 2016 for patients with ASC and AC of the colon. Kaplan-Meier survival analysis was performed to assess OS.
Background: There is little consensus with regards to the most appropriate surgical management for low-grade appendiceal mucinous adenocarcinomas (LAMA), though right hemicolectomy is usually recommended.
Methods: The SEER database was queried for all patients with non-metastatic LAMA. Disease specific and overall survival was compared by surgery type: 1) appendectomy, 2) formal right hemicolectomy 3) non-formal colectomy (including ileocecectomy).
