Burden of cervical cancer in India: estimates of years of life lost, years lived with disability and disability adjusted life years at national and subnational levels using the National Cancer Registry Programme data.

Abstract

Background: Cervical cancer is ranked as the second most common cancer in India. This study aims to assess the cervical cancer burden at the national and subnational level in India, projecting it for the year 2025 in terms of years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life years (DALYs).

Methods: Twenty-eight population based cancer registries within the National Cancer Registry Programme network contributed cancer incidence and mortality data for this analysis. The DisMod-II tool, WHO lifetables, disability weights, mortality to incidence ratio, sample registration system, and census data were used to estimate the burden of cervical cancer. The projection estimates for 2025 were performed using a negative binomial regression model.

Results: In 2016, the cervical cancer burden in India was 223.8 DALYs per 100,000 women. The highest age-standardised DALYs were found in the northeast region (290.1 DALYs per 100,000 women) and the lowest in the eastern region (156.1 DALYs per 100,000 women). The states of Mizoram, Arunachal Pradesh, Karnataka, and Nagaland had a higher cervical cancer burden with DALYs exceeding 300 per 100,000 women. The projected cervical cancer burden for India in 2025 was estimated to be 1.5 million DALYs.

Conclusions: The study has found a significant cervical cancer burden across the regions of India, providing a baseline for monitoring impact of actions. Enhancing awareness of cervical cancer, advocating for the significance of screening, and promoting HPV vaccination among adolescents, families, and communities through informative communication campaigns are essential steps in managing and ultimately eliminating cervical cancer in India.
