Caloric Restriction In Sarcoma Patients Treated With Pre-Operative RT

Not Applicable

Recruiting

• Conditions: Tumor Surgery

• Registration Number: NCT02792270
• Lead Sponsor: Massachusetts General Hospital

Brief Summary

This study is being conducted to decrease the rate of surgical wound complications. The investigators are studying the effects that caloric restriction has on decreasing the rate of surgical wound complications.

Detailed Description

The goal is to decrease the chance of having wound complications after surgery. Caloric Restriction has been found to be a natural modifier of surgical outcomes. Participants will be randomize into the arms Caloric Restriction Diet or Normal Diet.

Primary Outcome Measures

Name	Time	Method
Change In The Rate Of Physical Function By MSTS	Baseline, 6 weeks, 3 months and 6 months visits after surgery	The Musculoskeletal Tumor Society Rating Scale (MSTS) is a clinician-based scoring system that is scored out of 35 points. A higher score indicates better physical function.
Change In The Rate Of Physical Function By TESS	Baseline, 6 weeks, 3 months and 6 months visits after surgery	The Toronto Extremity Salvage Score (TESS) is a patient-reported scoring system that is scored out of 100 points. A higher score indicates better physical function.

Secondary Outcome Measures

Name	Time	Method
The Rate Of Wound Healing	2 years
The Rate Of Wound Complications In The Protein Caloric Restriction (PCR) Versus Control Group	2 years
