Predicting survival in head and neck cancer: External validation and update of the prognostic model OncologIQ in 2189 patients.

ABSTRACT:

Background

Disclosing prognostic information is necessary to enable patients to make well-informed treatment decisions. OncologIQ is a prognostic model that predicts the overall survival (OS) probability in patients with head and neck squamous cell carcinoma (HNSCC). We aimed to externally validate and update the model with new prognostic factors and translate it to a clinically useful tool.

Methods

A consecutive retrospective sample of 2189 patients eligible for curative treatment of a primary HNSCC were selected. Discriminative performance was determined using the C-statistic.

Results

External validation showed systematic underestimation of OS in the new population, and reasonable discrimination (C-statistic 0.67). Adding smoking, pack years, BMI, weight loss, WHO p
