Analysis of the Mortality Trends of 23 Major Cancers in the Indian Population Between 2000 and 2019: A Joinpoint Regression Analysis.

PURPOSE: Cancer mortality trends have not been documented across the population of India. We, therefore, analyzed the overall and individual cancer mortality trends for 23 major cancers between 2000 and 2019 on the basis of Global Health Observatory (GHO) database.

MATERIALS AND METHODS: This study examined cancer mortality trends for 23 major cancer sites on the basis of 12.85 million cancer deaths obtained from the GHO of the WHO between 2000 and 2019. A joinpoint regression model was used to analyze the long-term trends of cancer mortality. Annual percentage change (APC) and average APC were estimated for various cancer sites.

RESULTS: Between 2000 and 2019, 12.85 million deaths occurred in India from 23 major cancers. The most common lethal cancers were mouth and oropharyngeal (15.6%), stomach (10.6%), lung (9.6%), breast (9%), and colorectal (8%) cancers. The mortality trend decreased by 0.19% annually among men and increased nonsignificantly by 0.25% among women; an increase of 0.02% was observed among combined sexes. Increasing mortality trends were seen among cancers of the lung, breast, colorectum, lymphoma, multiple myeloma, gallbladder, pancreas, kidney, and mesothelioma between 2000 and 2019. The highest annual increase in mortality was observed in pancreatic cancer among both sexes: 2.7%, 2.1% among men, and 3.7% in women. The cancers of the stomach, esophagus, leukemia, larynx, and melanoma showed a declining cancer mortality trend irrespective of sex.

CONCLUSION: A multifaceted strategy is required to tackle the rising cancer mortality rates in India; the best long-term strategy could be implementing awareness on cancer symptoms among the population as well as cancer prevention policies with improved health infrastructure and specifically dedicated human resources.
