Abstract
Background: There is no reliable prognostic and predictive biomarkers for clear cell renal cell carcinoma (cc-RCC).
Methods: DNA from 47 cc-RCC tissue samples were sequenced using next generation sequencing and a customized gene panel testing for tumor-driver genes including 19 Mucin genes.
Results: Distinctive variants in 12 Mucin genes were present in all samples. These genes are: MUC2, MUC3A, MUC4, MUC5AC, MUC5B, MUC6, MUC7, MUC12, MUC16, MUC17, MUC19, and MUC22. The numbers of distinctive and non-distinctive variants were counted for each sample. The median number of variants was 455. High variant number (HVN) (>455) was associated with shorter overall survival compared to low variant number (≤455) [Median 50 months vs. not reached; P=0.041]. In the 11 patients who received anti-angiogenic tyrosine kinase inhibitors (TKIs), HVN was associated with a trend of shorter progression free survival.
Conclusion: Alterations in Mucin family genes are common in ccRCC. HVN is associated with worse prognosis and may predict decreased benefit from anti-angiogenic TKIs.
