Low-grade Serous Tumors: Are We Making Progress?

Purpose of Review This review provides an overview of the current clinical standard in low-grade serous ovarian cancer (LGSOC). The available evidence for surgery and standard treatments is elaborated. In addition, we discuss recent findings and novel treatments for LGSOC. Recent Findings Two large multicenter trials studying MEK inhibitors in LGSOC have been presented in the last year. Binimetinib demonstrated an activity in LGSOC, especially in KRAS -mutated disease. Trametinib was associated with an improved progression-free survival in relapsed LGSOC. Based on the current results, MEK inhibitors could be an alternative treatment for LGSOC. Summary Surgery is an important step in the treatment of LGSOC. Hormonal therapy and bevacizumab can be beneficial, next to chemotherapy. Targeted treatments, such as the MEK-inhibitor trametinib, seem to be efficient and should be introduced into clinical practice.
