Assessment and projection of burden of cancer due to tobacco in India till 2025

Abstract

Background: For effective planning and optimum allocation of resources, accurate assessment of burden due to tobacco and its projection is essential. There are number of reports in India during last 3-4 decades, reporting tobacco related cancers (TRC). However, there is no visible study in India attempting to assess cancers due to tobacco (CDT). Objectives: To assess CDT in India and States by sex and urban/rural and project the same till 2025. Materials and methods: The basic inputs required were 1) tobacco prevalence, 2) relative risk of cancer due to tobacco, 3) incidence rates of TRCs, and, 4) population. These were obtained respectively from 1) recent five rounds of NSSO, 2) our recently published study, 3) reports of PBCRs, and, 4) projections of Registrar General of India. Our recently published method was applied to assess the CDT and regression method for projection. Results: The overall burden of CDT in India was estimated to be 169 thousands in 2015 and it was projected to around 236 thousands by 2025, an increase of nearly 39.6%. CDT accounted for nearly half of TRCs. The CDT as percentage of TRC was highest for Tripura followed by Meghalaya, Manipur, Mizoram and West Bengal. Detailed analysis indicated regional diversity in both CDT and TRCs. Conclusions: Present study reports absolute burden of CDT as well as the same as a percentage of TRC for India and its States till 2025. This may help policy planners and administrators in prioritizing the resources and proactive decisions pertaining to anti-tobacco measures. Non-availability of enough PBCRs to capture regional diversity may also be addressed by competent authorities.

Epidemiology of human papillomavirus related cancers in India: findings from the National Cancer Registry Programme

“…Reported variations in HPV prevalence among cancer cases in India are due to different detection methods, population, geographic locations and sample size. However, major proportion could be attributed to tobacco use (59.0%) and consumption of alcohol (4.7%) [34,35]. Existing policies and programmes to prevent and control these risk factors should be reinforced to bring down cancer burden [36].…”

“…Globally in 2018, human papillomavirus (HPV) accounted for 31% cancer cases amongst 13% of all human infection related incident cancer cases [1]. HPV types 16,18,26,31,33,35,39,45,51,52,53,56,58,59, 66, 68, 73 and 82 are classified as carcinogenic to humans [2]. Persistent HPV infection (especially HPV types 16 and 18) is known to cause the cervical cancers and a significant proportion of the anogenital and head and neck cancers [3].…”

Effect Of Pranayama on Reducing the Level of Fatigue During External Radiation Therapy Among the Patients in A Cancer Hospital of Guwahati, Assam India

“…A study revealed that in states namely Manipur, Mizoram, Tripura, Meghalaya, and Assam the number of cancer cases due to tobacco is around 60 percent of other respective states. 1 A study conducted by B. Barooah Cancer Institute (BBCI) reported cancer statistics in Kamrup Urban District, including incidence and mortality, revealed the statistics of remarkable growth of cancer cases in Assam. The number of new cases of all cancer was increased from 155.3 to 188.5 and 102.7 to 165.3 per 100,000 men and women respectively from the year 2007 to 2011.…”
