Abstract

The development of resistance toward current cancer therapy modalities is an ongoing challenge in gynecological cancers, especially ovarian and cervical malignancies that require further investigations in the context of drug- and irradiation-induced resistance. In this regard, curcumin has demonstrated beneficial and highly pleiotropic actions and increased the therapeutic efficiency of radiochemotherapy. The antiproliferative, anti-metastatic, anti-angiogenic, and anti-inflammatory effects of curcumin have been extensively reported in the literature, and it could also act as a chemopreventive agent which mitigates the out-of-target harmful impact of chemotherapeutics on surrounding normal tissues. The current review discussed the modulating influences of curcumin on some cell and molecular features, including the cell signaling and molecular pathways altered upon curcumin treatment, the expression of target genes involved in the progression of gynecological cancers, as well as the expression of genes accountable for the development of resistance toward common chemotherapeutics and radiotherapy. The cell molecular targets implicated in curcumin�s resensitizing effect, when used together with cisplatin, paclitaxel, and irradiation in gynecological cancers, are also addressed. Finally, rational approaches for improving the therapeutic benefits of curcumin, including curcumin derivatives with enhanced therapeutic efficacy, using nanoformulations to advance curcumin stability in physiological media and improve bioavailability have been elucidated. © 2018, Springer International Publishing AG, part of Springer Nature.
