Pharmacotherapeutic treatment options for recurrent epithelial ovarian cancer
Almost 80% of epithelial ovarian cancer present in advanced stage at diagnosis and despite excellent response to surgery and chemotherapy, more than 70% cancers recur. Subsequent therapies become decreasingly effective in controlling the disease, with each successful therapy being effective for a shorter duration. As a result, there is a need for novel therapeutic strategies to effectively treat recurrence. In this extensive literature review of high-quality articles, we have focused on surveillance strategy to detect recurrence early, classification of recurrence based on timeline, role of surgery, chemotherapy, and targeted agents such as anti-angiogenetic drugs, PARP inhibitors, and immune checkpoint inhibitors in platinum-sensitive and platinum-resistant disease, respectively. Recurrent ovarian cancers (ROC) are represented by a heterogenous group of patient population in terms of platinum-free interval (PFI), histology, molecular characteristics and immune recognition. In today's era of precision medicine, chemotherapy should be combined with appropriate targeted agent in a multipronged approach to prolong survival and provide better quality of life outcomes by minimizing side effects.
