Fallopian Tube High Grade Serous Adenocarcinoma

This clinical trial develops a non-surgical approach using uterine lavage samples to screen for progression to ovarian cancer in high-risk patients carrying BRCA mutations. Women with inherited mutations in the BRCA1 and BRCA2 genes (BRCA carriers) have a much higher lifetime risk of developing ovarian cancer. Currently there are no effective ovarian cancer screening or early detection tests for BRCA carriers. Uterine lavage is a procedure that uses saline to rinse and collect cells from the fallopian tube. Molecular analysis of these samples may help proactively detect genetic alterations that are indicative of progression to ovarian cancer in women with BRCA mutations.

This phase III trial compares the effect of olaparib for one year versus two years, with or without bevacizumab, for the treatment of BRCA 1/2 mutated or homologous recombination deficient stage III or IV ovarian cancer. Olaparib is a polyadenosine 5'-diphosphoribose polymerase (PARP) enzyme inhibitor and may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Bevacizumab is in a class of medications called antiangiogenic agents. It works by stopping the formation of blood vessels that bring oxygen and nutrients to tumor. This may slow the growth and spread of tumor. Giving olaparib for one year with or without bevacizumab may be effective in treating patients with BRCA 1/2 mutated or homologous recombination deficient stage III or IV ovarian cancer, when compared to two years of olaparib.
