Background: Human Papilloma Virus (HPV) infection and its persistence are responsible for the development of cervical cancer (CaCx). Chemoradiotherapy (CRT) is the only treatment option, especially in advanced stages. However, it is not influenced by the status of HPV infection. CRT controls cancer growth along with mild to severe adverse effects. Objective: The aim of this study was to assess the HPV-associated risk factors and correlate them — with chemoradiation therapy (CRT) response in cervical cancer. Methods: The study was undertaken in 103 histologically positive CaCx patients. Anthro- demographic and obstetric characterizations were conducted by face-to-face interviews, and HPV testing was done by conventional PCR. All the patients received a 40-50Gy total effective dose using tele- and brachytherapy. The treatment response, survivorship and statistical analysis were made using GraphPad Prism 9 and SPSS (ver.25.0). Results: Out of 103 patients, 84% were HPV infected, and 16% CaCx were HPV-negative. Advanced age, lower-middle socioeconomic status (SES), illiteracy, and patients from rural backgrounds were significantly higher in CaCx patients with HPV infection. Multiparity, irregular menstrual cycle, poor menstrual hygiene, and use of contraception were significantly associated with HPV positivity. Patients with HPV infection showed a better clinical response (P =0.031), alive vital status (P =0.007), and 59 months of median survival (P<0.001) with a poor hazard ratio (HR 0.29 at 95% CI). Conclusion: HPV-infected CaCx patients showed better response to definitive chemoradiation therapy compared to HPV-negative with a poor hazard ratio. Therefore, HPV testing can potentially stratify CaCx patients for more effective therapeutic regimens, treatment assessments and follow-ups. © 2024, Bentham Science Publishers. All rights reserved.
