Complete Response With Trametinib in Advanced Low-Grade Serous Ovarian Carcinoma: A Case Report
View abstract on PubMed
Summary
This summary is machine-generated.A patient with recurrent low-grade serous ovarian carcinoma (LGSOC) achieved a complete response with trametinib, a MEK inhibitor. This case highlights potential efficacy of targeted therapy in advanced LGSOC.
Area Of Science
- Oncology
- Genetics
- Pharmacology
Background
- Low-grade serous ovarian carcinoma (LGSOC) presents unique challenges due to chemoresistance and poor prognosis.
- Standard treatment often involves platinum-based chemotherapy and cytoreduction, but recurrence is common.
Observation
- A 45-year-old female with stage III-C LGSOC experienced relapse after initial chemotherapy and cytoreduction.
- Hormonal therapy was ineffective, and chemotherapy was refused; bevacizumab provided 30 months of stabilization.
Findings
- Single-agent trametinib, a MEK inhibitor, induced a sustained complete response for over 36 months in recurrent LGSOC.
- This represents the first reported complete response to a MEK inhibitor outside clinical trials for recurrent LGSOC with unknown BRAF V600E mutation.
Implications
- Trametinib may offer a novel therapeutic option for patients with advanced or recurrent LGSOC, particularly those refractory to other treatments.
- Further investigation into MEK inhibitor efficacy in LGSOC, irrespective of BRAF mutation status, is warranted.
