Objectives:	To evaluate the efficacy of oral cancer screening by visual inspection in detecting early stages of oral cancer and in reducing mortality To evaluate the cost-effectiveness of the intervention
Methodology:
Study outcomes:	In 1996–2004, three rounds of oral visual inspection were provided by trained health workers at 3-year intervals to eligible individuals (aged ≥ 34 years) in the intervention group. We reported a 35% decrease in mortality rate among the tobacco users/alcohol consumers of the intervention group compared with the control group. This evidence was used by India’s National Programme for Prevention and Control of Cancer, Diabetes, Cardiovascular Disease and Stroke (NPCDCS) to support their recommendation of oral visual screening of the population.

Objectives:	Overall objective To elucidate the role of HPV types and other environmental risk factors in the development of head and neck cancers (HNCs) in Europe and India Specific objectives: To improve our understanding of the role of HNC etiology in geographical regions with different incidence rates To identify the most clinically useful HPV markers and new biomarkers for various types of HNC, which can be used for screening and/or therapy strategies To provide new insights on the natural history of HPV oral infection and its diagnosis, on HNC prognosis, and the association of survival with HPV status
Methodology:	This is a multicentre study including recruiting centres in Europe and India. The Screening Group is collaborating with the Indian centres. Approximately 4000–6000 HNC specimens are collected from several Indian centres from rural or urban areas. The specimens include cancers of the hypopharynx, oropharynx, oral cavity, and larynx. Each Indian centre provides approximately 1000–1500 specimens representing the four anatomical sites. Epidemiological and clinical data are also collected when available.

Objectives:	To evaluate the feasibility and acceptability of the model of delivering community health worker (CHW)–driven home-based comprehensive noncommunicable disease (NCD) control services aimed to prevent premature deaths from cardiovascular diseases; stroke; and breast, cervical, and oral cancers in hard-to-reach men and women
Methodology:	The implementation research has two main components, which will be conducted simultaneously: Evaluation of the social, cultural, and behavioural factors that impact the uptake of the NCD prevention and control services among women, using the RARE methodology Evaluation of the feasibility and acceptability of delivery of the NCD early detection services by the trained community health workers in home settings Participants will be screened for hypertension, diabetes, oral cancer (for habitual users of tobacco products and/or consumers of alcoholic beverages), and cervical cancer (for women only, by HPV testing on self-collected specimens). Women will be made aware of common symptoms and signs of breast cancer. All services will be provided at home. The screen-positive men and women will be navigated to reach appropriate diagnostic and treatment centres.
