A 13-gene signature prognostic of HPV-negative OSCC: discovery and external validation

ABSTRACT: OSCC is associated with substantial mortality and morbidity. In this study, we built on our previous molecular work to identify and validate a prognostic 13-gene signature that showed a higher ability than tumor stage in predicting survival for patients with HPV-negative oral squamous cell carcinoma (OSCC). We previously reported 131 genes to be associated with survival in OSCC patients. In this study, we applied L1/L2-penalized Cox regression models to the Affymetrix array data from 97 HPV-negative OSCC patients on the 131 gene to identify a model for prediction of OSCC-specific survival. We then tested the model in an independent dataset and compared to tumor stage.

Discovery and Validation of a 15-Gene Prognostic Signature for Clear Cell Renal Cell Carcinoma

Project description:We report a kidney cancer tissue-based prognostic biomarker encompassing 15 genes (15G score) to classify patients into low versus high risk for recurrence after curative nephrectomy. The 15G score was independently associated with disease free survival adjusting for clinicopathologic variables as well as existing clinical risk calculators or nomograms. By improving risk stratification of patients with ccRCC, the 15G score has the capacity to facilitate selection of biopsy confirmed small renal cancers (T1a) for treatment versus surveillance; inform intensity and duration of surveillance after curative nephrectomy; and to potentially facilitate patient selection for adjuvant systemic therapy. We retrospectively identified 110 patients who underwent radical nephrectomy for ccRCC (discovery cohort). Patients who recurred were matched based on grade/stage to patients without recurrence. Capture whole transcriptome sequencing was performed on RNA isolated from archival tissue using the Illumina platform. We developed a gene-expression signature to predict recurrence/disease-free survival (DFS) using a 15-fold lasso and elastic-net regularized linear Cox model. We derived the 31-gene cell cycle progression (mxCCP) score using RNAseq data for each patient. Kaplan-Meier (KM) curves and multivariable Cox proportional hazard testing were used to validate the independent prognostic impact of the gene-expression signature on DFS, disease specific survival (DSS) and overall survival (OS) in two validation datasets (combined n=761).
