Background: Cervical cancer is most common malignancy of female reproductive system worldwide. As per GLOBOCAN 2020, there are 604,127 (6.5%) new cases of cervical cancer in the world, among women it is fourth most common and eighth most common in both sexes. In India,there are 123,907 total new cervical cancer cases (18.3% in female sex whereas 9.4% in both sexes). There are several etiological factors and the most significant is due to persistent infection of specific human papilloma virus (HPV) strains,particularly type 16 and 18 which are most common. Screening and early detection is likely to improve mortality and incidence also.
Aims and objectives: The objective of this retrospective study was to determine the survival rates of cervical cancer and its associated factors in North-West region.
Materials and methods: A total of 520 newly diagnosed cases of cervical cancer were enrolled at Acharya Tulsi Regional Cancer Treatment and Research Centre, Bikaner from January 1, 2014 to December 31, 2014 were included in this study. The main source of information was patient's medical records from which the data were abstracted and cases were followed up for next five years periodically from the date of diagnosis to access their survival status.
Results: Kaplan Meier analyses were conducted to identify overall survival and median survival time. Among 520 cases, 130 (25%) had lost to follow up so excluded from the study and the study sample was about 390 patients. The median survival time for cervical cancer in this study was 60 (32-60) months and the overall survival rates at 1, 3 and 5 years were 93.07%, 72.3% and 54.9% respectively. Education, use of oral contraceptive pills (OCP), tobacco chewing ( good survival in tobacco non-chewers) and staging were significantly associated with survival.
Conclusion: The 1, 3 and 5 year survival rates for cervical cancer were found to be 93.07%, 72.3% and 54.9% respectively. Various factors determining survival rates were potentially modifiable. Early diagnosis and prevention strategies are keys to obtain better outcomes.
