Abstract

Background: Tumor suppressors are well known drivers of cancer invasion and metastasis in metastatic castration sensitive prostate cancer (mCSPC). However, oncogenes are also known to be altered in this state, however the frequency and prognosis of these alterations are unclear. Thus, we aimed to study the spectrum of oncogene mutations in mCSPC and study the significance of these alteration on outcomes.

Methods: Four hundred and seventy-seven patients with mCSPC were included who underwent next generation sequencing. Oncogene alterations were defined as mutations in ALK, AKT1-3, BRAF, CCND1-3, CTNNB1, EGFR, ERBB2, FGFR1, FGFR2, HRAS, KRAS, MDM2, MET, MITF, MYC, NOTCH1-3, NRAS, PIK3CA, PI3KCB, PIK3R1, RET. Endpoints of interests were radiographic progression-free survival (rPFS), time to development of CRPC (tdCRPC), and overall survival (OS). Kaplan Meier analysis was performed and Cox regression hazard ratios (HR) calculated.

Results: A total of 477 patients were included with baseline characteristics with 117 patients (24.5%) harbored a mutation within an oncogene. A total of 172 oncogene mutations were found within the population with the most common being MYC (n=29; 16.9%), PIK3CA (n=24; 14%), CTNNB1 (n=22, 12.8%), BRAF (n=10, 5.8%), and CCND1 (n=10, 5.8%). Oncogene mutations were associated with inferior rPFS (19.2 vs. 32.2 months, P=0.03), tdCRPC (15.7 vs. 32.4 months, P<0.001), and OS (5-year OS 75.3% vs. 55.4%, P=0.01). On multivariable analysis oncogene mutations were strongly associated with tdCRPC (HR 1.42, P=0.03).

Conclusions: Oncogenes are frequency mutated in mCSPC and associated with aggressive features and inferior outcomes. Future work will need to validate these results to better assess its significance in allowing for personalization of care.

期刊介绍： Translational Cancer Research (Transl Cancer Res TCR; Print ISSN: 2218-676X; Online ISSN 2219-6803; http://tcr.amegroups.com/) is an Open Access, peer-reviewed journal, indexed in Science Citation Index Expanded (SCIE). TCR publishes laboratory studies of novel therapeutic interventions as well as clinical trials which evaluate new treatment paradigms for cancer; results of novel research investigations which bridge the laboratory and clinical settings including risk assessment, cellular and molecular characterization, prevention, detection, diagnosis and treatment of human cancers with the overall goal of improving the clinical care of cancer patients. The focus of TCR is original, peer-reviewed, science-based research that successfully advances clinical medicine toward the goal of improving patients'' quality of life. The editors and an international advisory group of scientists and clinician-scientists as well as other experts will hold TCR articles to the high-quality standards. We accept Original Articles as well as Review Articles, Editorials and Brief Articles.
