In Brief Objective: We sought to examine the effect of body mass index (BMI) on 30-day morbidity and mortality in a large cohort patients undergoing nonbariatric general surgery. Summary Background Data: Obesity has long been considered risk factor for poor outcomes from variety surgical procedures, yet recent studies critically chronically ill suggest that overweight obese may paradoxically have better than “normal” weight patients. Methods: A prospective, multi-institutional, risk-adjusted...

Carcinoid tumors of the appendix are rare, and as such there few data guiding their optimal treatment.The analysis included all patients with malignant, typical carcinoid tumor for whom complete were available in Surveillance, Epidemiology, End Results database between 1988 2003. Clinicopathologic factors predicting lymph node (LN) involvement survival determined.LN metastases present 44 89 (49%), including 4 27 (15%) ≤ 1.0 cm, 16 34 (47%) > cm but 2.0 24 28 (86%) >2.0 cm.

We evaluated the efficacy and safety of risk-adapted, proton-based stereotactic body radiation therapy (SBRT) for liver metastases from solid tumors.This single-arm phase II single institutional study (NCT01239381) included patients with limited extrahepatic disease, 800 mL or greater uninvolved liver, no cirrhosis Child-Pugh A, who had received SBRT to one four tumors. Treatment comprised 30 50 Gray equivalent (GyE) in five fractions based on effective volume irradiated. Sample size was...

Abstract Purpose: The role of surgery for first relapse locally recurrent retroperitoneal sarcoma (RPS-LR1) is uncertain. We report outcomes the largest RPS-LR1 series and propose a new prognostic nomogram. Experimental Design: Patients with consecutive without distant metastases who underwent resection at 22 centers (2002–2011) were included. Endpoints disease-free overall survival (DFS, OS) crude-cumulative-incidence (CCI) local/distant recurrence from second surgery. Nomograms predicting...

Patient-generated health data captured from smartphone sensors have the potential to better quantify physical outcomes of surgery. The ability these discriminate between postoperative trends in activity remains unknown.To assess whether accelerometer can be used describe recovery among patients undergoing cancer operations.This prospective observational cohort study was conducted July 2017 April 2019 a single academic tertiary care hospital United States. Preoperatively, adults (age ≥18...
