Association between FAT1 mutation and overall survival in patients with human papillomavirus-negative head and neck squamous cell carcinoma.

ABSTRACT:

Background

The purpose of this study was to characterize the mutation profile of FAT atypical cadherin 1 (FAT1) and determine the prognostic significance of FAT1 mutation for overall survival in patients with human papillomavirus (HPV)-negative head and neck squamous cell carcinoma (HNSCC).

Methods

Data were downloaded from The Cancer Genome Atlas (TCGA) and International Cancer Genome Consortium (ICGC) data portals and used as discovery and validation sets. FAT1 mutational status was determined in 234 and 37 patients with HPV-negative HNSCC, respectively, and overall survival analysis was performed. For comparison, HPV-positive patients were also analyzed for overall survival.

Results

Most of the identified nonsynonymous somatic FAT1 mutations were loss-of-function m
