Abstract

PARP inhibitors are considered as a treatment revolution in ovarian cancer management. Leptomeningeal metastasis is a rare event with poor prognosis. The present report presents an exceptional history of long term survival for a young patient treated with olaparib for carcinomatous meningitis. A 54‑year‑old woman was diagnosed with ovarian cancer. After Paclitaxel and Carboplatin treatment, followed by a debulking surgery and several lines of chemotherapy due to progression, the patient's disease evolved into carcinomatous meningitis within 6 months after the end of treatment. During care, exome analysis on brain lesions was performed. Exome analysis was performed with a mean coverage of 80X by a paired‑end sequencing on an Illumina NextSeq500 device. Following bioinformatics alignment and variant annotation, a pathogenic BRCA2 mutation, c.7617+1G>T, was observed, and this was already detected in her family. Additionally, the allelic frequency observed indicated that the mutation was present at the homozygous status in tumor cells. Due to the presence of a pathogenic mutation and a loss of wild‑type BRCA2 allele, a maintenance treatment by Olaparib was initiated after radiotherapy and Cisplatin monotherapy. The patient received olaparib treatment for 14 months with a very good disease control and an excellent tolerance. Despite long control, the patient succumbed to meningeal and peritoneal progression.
