Background: Cervical Cancer is still significant cause of mortality and morbidity among females in India. Various methods of cancer screening are currently practiced for cervical cancer prevention including human papilloma virus (HPV) screening, pap smear, visual inspection with Lugol’s iodine (VILI), visual inspection with acetic acid (VIA) etc. The success of any cancer screening method is based on the feasibility of large-scale implementation at community level and the scientific validity of the screening test. VIA/VILI has been proven to prevent mortality in cervical cancer. This study is based on analysis of prospectively maintained database of community based cervical cancer screening using VIA/VILI in northern Kerala from 2002 to 2020. Methods: Retrospective analysis of prospective database of cervical cancer screening from 2002 to 2020 done by Malabar Cancer Care Society in Kerala, a non-governmental organization with support from governmental bodies like ISRO. Data was collected into excel sheets and were rechecked. The data on demography, type of screening, detection of precancerous and cancerous lesions was analyzed. Descriptive statistics were used to analyze the data using SPSS Version 20.0. Results: A total of 48008 individuals were screened over 18 years. 55% were premenopausal. 33% were fully asymptomatic and remaining 66% had white discharge per vaginum (25%), bleeding per vaginum (14%) or combination of symptoms (25%). 18% had abnormal per speculum findings (bleeds on touch, discharge etc.) 86% had unhealthy cervix.26% (12650) had VIA/VILI and 74% (35658) had pap smear. The pap smear findings were normal (41%), atrophic (17%), inflammatory (40%) and 2% had pre-cancerous/ cancerous changes. Of these lesions, 46% were HSIL, 36% were LSIL, 5% ASUS and 13% were squamous cell carcinoma (52 cases). Screen positive rate was 325 (0.005%) out of 48008. Treatment of precancerous lesions was by Cryotherapy (54%), LEEP (10%) and Surgery (36%). Treatment of invasive carcinoma was by surgery (91%) and radiation (85%). Referral to regional cancer center was done in 26% patients. The screen positive rate shows decreasing trend over the last two decades. Conclusions: Cervical Cancer screening in large scale in low resource setting is feasible in India by both pap smear and VIA/VILI with community based interventions led by NGO with support from governmental bodies. This model can be considered ideal for India and other low middle income countries with logistic difficulties for large scale HPV based screening.
