Immunotherapy in Cervical Cancer: An Evolutionary Paradigm in Women's Reproductive Health.

Cervical cancer is the fourth most common cause of morbidity and mortality in women. The major causative factor for cervical cancer is primary prolonged infection with human papillomavirus, along with secondary factors such as immunodeficiency, smoking, low socioeconomic standards, poor hygiene, and overuse of oral contraceptives. A grave need exists to practice novel strategies to overcome existing drawbacks of conventional therapy such as chemotherapy, radiation therapy, and surgery. Cancer immunotherapy works by strengthening the immune system of the host to combat against the cancerous cells. Immunotherapy in cervical cancer treatment has demonstrated long-lasting effects; however, the response to such therapies was nominal due to its prominent limitations such as immunosuppressive behavior of the tumor. Presently plethora of nanoplatforms such as polymeric nanoparticles, micelles, liposomes, and dendrimers are being maneuvered with cancer immunotherapy. The amalgamation of nanotechnology and immunotherapy in the treatment of cervical cancer is conceivable due to the mutual association between the tumor microenvironment and immunosurveillance. Safety concerns of nanoplatforms with immunotherapeutics such as toxicity, inflammation, and unwanted accumulation in tissues could be surmounted by surface modification methods. This review highlights the benefits of the amalgamation of nanotechnology and immunotherapy to improve shortcomings applicable to the conventional delivery of cancer treatment. We also aim to outline the nanoimmunotherapy sophistications and future translational avenues in this rapidly flourishing cancer treatment modality.
