Preoperative nutritional support to tackle morbidity in multivisceral resection for retroperitoneal sarcoma. Early outcomes from a novel nutritional prehabilitation program in a prospective cohort.

Objective: Evaluate the feasibility and outcomes of the implementation of a routinely prehabilitation nutritional program (PNP) in retroperitoneal sarcoma (RPS) patients.

Summary Background Data: Rate of preoperative malnutrition is scarcely evaluated in RPS patients and the efficacy of a PNP in detecting and reverting malnutrition has not been studied.

Methods: Prospective study in a high-volume reference center for RPS; adult patients with primary or persistent RPS deemed surgically resectable were enrolled in a PNP.

A Prospective Observational Study of Multivisceral Resection for Retroperitoneal Sarcoma: Clinical and Patient-Reported Outcomes 1 Year After Surgery.

Background: Primary retroperitoneal sarcoma (RPS) may require multivisceral resection (MVR). Clinical outcome (morbidity and renal function) and quality of life (QoL) are not as well reported as the oncologic outcome.

Methods: Patients with primary RPS who underwent surgery between 2014 and 2016 were prospectively enrolled in an observational longitudinal study.

Malnutrition and Perioperative Nutritional Support in Retroperitoneal Sarcoma Patients: Results from a Prospective Study.

Introduction: Retroperitoneal soft tissue sarcomas (RPSs) are mesenchymal neoplasms. The prevalence of protein energetic malnutrition (PEM) and its impact in RPS patients who were candidates for surgery is unknown.

Materials And Methods: A prospective feasibility study enrolled 35 patients with primary RPS who were candidates for extended multivisceral resection.
