Nutritional and immunological parameters as prognostic factors in patients with advanced oral cancer Study conducted at the Cancer Institute of São Paulo (ICESP), University of São Paulo Medical School, São Paulo, SP, Brazil.

Abstract

Objective:

The aim of the present study was to analyze the prognostic relationship of weight loss and preoperative hematological indexes in patients surgically treated for pT4a squamous cell carcinoma of the oral cavity.

Methods:

A retrospective cohort study.

Results:

Percent weight loss greater than 10% was identified in 49 patients (28.2%), and any weight loss in relation to the usual weight occurred in 140 patients (78.7%). Percent weight loss greater than 10% (HR = 1.679), Red cell distribution width (RDW) values greater than 14.3% (HR = 2.210) and extracapsular spread (HR = 1.677) were independent variables associated with risk of death.

Conclusion:

Patients with advanced squamous cell carcinoma of the oral cavity present significant weight loss and as significantly immunocompromised. Increased values of RDW and higher percentages of weight loss in relation to the individual’s usual weight, together with extracapsular spread of metastatic lymph nodes, were risk factors for lower survival, regardless of other clinical and anatomopathological characteristics.

Level of evidence:

3.

HIGHLIGHTS

Patients with oral SCC present significant weight loss and immune compromise.

Increased values of RDW and high weight loss were risk factors for lower survival.

Patients undergoing treatment must receive a complete nutritional evaluation.

Nutritional intervention can be effective, preventing nutritional deterioration.
