The relevance of population-based cancer registries for planning and implementing cancer control programmes cannot be overemphasized. There are some urban registries in India but very few rural registries despite India being predominantly rural. There are several obstacles to setting up a rural registry including lack of cancer awareness in the rural population and inaccessibility of modern medical facilities. The first rural cancer registry was set up in 1987 at Barshi (population 0.4 million) in western Maharashtra by adopting a methodology suitable for rural areas. ⋯ The innovative methodology has facilitated the process of cancer registration in rural areas. It has had a positive impact on cancer awareness, stage at presentation and survival of cervical cancers-the predominant cancer in the area. The registry has created a resource for epidemiological studies in a rural area where national and international studies are currently being undertaken.

Reliable estimates of heart failure are lacking in India because of the absence of a surveillance programme to track incidence, prevalence, outcomes and key causes of heart failure. Nevertheless, we propose that the incidence and prevalence rates of heart failure are rising due to population, epidemiological and health transitions. Based on disease-specific estimates of prevalence and incidence rates of heart failure, we conservatively estimate the prevalence of heart failure in India due to coronary heart disease, hypertension, obesity, diabetes and rheumatic heart disease to range from 1.3 to 4.6 million, with an annual incidence of 491 600-1.8 million. ⋯ Staging of heart failure, introduced in 2005, provides a framework to target preventive strategies in patients at risk for heart failure (stage A), with structural disease alone (B), with heart failure symptoms (C) and with end-stage disease (D). Policy-level interventions, such as regulations to limit salt and tobacco consumption, are effective for primordial prevention and would have a wider impact on prevention of heart failure. Clinical preventive interventions and clinical quality improvement interventions, such as treatment of hypertension, atherosclerotic disease, diabetes and acute decompensated heart failure are effective for primary, secondary and even tertiary prevention.
