ABSTRACT
OBJECTIVE:
Molecular tumor profiling and next-generation sequencing are being increasingly utilized, but there are limited data on the therapeutic implications and potential benefits of targeted treatments. We aim to characterize gynecologic oncology patients referred for somatic tumor genetic mutation testing and assess survival outcomes, efficacy, and toxicities of those receiving targeted therapy.METHODS:
We conducted a retrospective chart review of gynecologic oncology patients referred for somatic tumor testing by next generation sequencing between 1/1/2012-8/23/2019. The primary objective was to compare overall and progression free survival between those treated with targeted therapy (group 1) versus traditional treatment (group 2).RESULTS:
Most patients (70%) had additional treatment options available based on actionable mutations. The median number of somatic mutations identified was 5 (range 0-53). Patients in group 1 had more actionable somatic mutations (median 2 versus 0, p < 0.001). There was no difference in OS (median 64 versus 76 months, p = 0.97) or PFS (median 2 versus 8 months, p = 0.05) between the groups. While fewer patients in group 1 experienced neuropathy (0 versus 5, p = 0.02), grade I/II thrombocytopenia (7 versus 13, p = 0.03), grade III/IV thrombocytopenia (0 versus 4, p = 0.02), and grade III/IV neutropenia (1 versus 9, p = 0.002), all other non-hematologic toxicities were similar in the two groups.CONCLUSIONS:
Most gynecologic cancer patients have actionable mutations and may benefit from a personalized targeted therapy treatment plan. Next generation sequencing can be used to identify clinically actionable mutations in gynecologic cancers and guide the selection of treatments, thereby expanding treatment options without worsening survival or toxicity.Palavras-chave
