Global cancer centres operate across different sizes, scales, and ecosystems. Understanding the essential aspects of the creation, organisation, accreditation, and activities within these settings is crucial for developing an affordable, equitable, and quality cancer care, research, and education system. Robust guidelines are scarce for cancer units, cancer centres, and comprehensive cancer centres in low-income and middle-income countries. However, some robust examples of the delivery of complex cancer care in centres in emerging economies are available. Although it is impossible to create an optimal system to fit the unique needs of all countries for the delivery of cancer care, we summarise what has been published about the development and management of cancer centres in low-income and middle-income countries so far and highlight the need for clinical and political leadership.

PURPOSE The burden of cancer is increasing globally, with poor outcomes in terms of morbidity and mortality in patients, especially in low- and middle-income countries. Lack of awareness of the risk factors, symptoms, and signs of common cancers in addition to inadequate cancer prevention programs at the community level are a major hindrance to the early detection of cancer. METHODS A cross-sectional study was conducted in the North East Region (NER) of India, with a sample population of 1,400 participants from Assam (n = 1,000), Meghalaya (n = 200), and Nagaland (n = 200). The questionnaire developed for the study consisted of sociodemographic profile, knowledge about cancer (oral, breast, and cervical), its warning signs, risk factors, and attitude toward cancer screening. Statistical analysis was performed using STATA version 13.0. RESULTS Among all the participants, 59% had heard about oral cancer, 50% about breast cancer, and 31% about cervical cancer. A limited understanding of risk factors, symptoms, and signs was reported for oral cancer (45%), breast cancer (54%), and cervical cancer (63%). A total of 34% of participants were aware of cancer screening. Among those who were aware of cancer screening, only six people had undergone any form of cancer screening, and 71% cited media as the major source of information. CONCLUSION The level of cancer awareness is low in the NER. A multipronged approach is needed with assistance from government and nongovernment organizations for training, providing adequate human resources and equipment, and developing cancer screening infrastructure. This needs to be coupled with mass media communication and interpersonal communication through frontline health workers.

In India, data on key developmental indicators used to formulate policies and interventions are routinely available for the administrative unit of districts but not for the political unit of parliamentary constituencies (PC). Recently, Swaminathan et al. proposed two methodologies to generate PC estimates using randomly displaced GPS locations of the sampling clusters (‘direct’) and by building a crosswalk between districts and PCs using boundary shapefiles (‘indirect’). We advance these methodologies by using precision-weighted estimations based on hierarchical logistic regression modeling to account for the complex survey design and sampling variability. We exemplify this application using the latest National Family Health Survey (NFHS, 2016) to generate PC-level estimates for two important indicators of child malnutrition – stunting and low birth weight – that are being monitored by the Government of India for the National Nutrition Mission targets. Overall, we found a substantial variation in child malnutrition across 543 PCs. The different methodologies yielded highly consistent estimates with correlation ranging r = 0.92-0.99 for stunting and r = 0.81-0.98 for low birth weight. For analyses involving data with comparable nature to the NFHS (i.e., complex data structure and possibility to identify a potential PC membership), modeling for precision-weighted estimates and direct methodology are preferable. Further field work and data collection at the PC level are necessary to accurately validate our estimates. An ideal solution to overcome this gap in data for PCs would be to make PC identifiers available in routinely collected surveys and the Census.

Background Areca nut is the fourth most commonly used psychoactive substance worldwide after tobacco, alcohol and caffeine. In India, it is perceived in various ways, ranging from a ‘fruit of divine origin’ in Hindu religious ceremonies to a mouth freshener. Areca nut use both on its own and with tobacco additives is addictive. The aim of this study was to understand the pattern of areca nut consumption, to determine the Knowledge, Attitude and Practices (KAP) among areca nut users and the dependency associated with areca nut use. Methods A cross sectional study was conducted in Guwahati, Assam using a self-administered questionnaire eliciting the pattern of areca nut consumption, KAP among users and understanding their dependency using Betel Quid Dependence Scale. The chewers of areca nut alone with or without betel quid, gutkha and tobacco participated in the study. Areca nut users were selected using purposive sampling method from the vendor shops of all the four assembly areas of the city. Their participation was voluntary and free not to answer or quit the survey. The data was analysed using SPSS software. Results A total of 500 participants were approached in all four areas, 479 completed the survey (response rate 95%). The people who participated in the study were mostly male with an average age of 40 years, educated to secondary level or higher, married and self-employed. Betel quid with tamul was the most prevalent form of areca nut chewing in both men and women. About 441 (92%) participants experienced pleasure when chewing areca nut and 327 (68%) chewed it to relieve stress. Only 86 (18%) of subjects had ever tried to quit chewing areca nut and 387 (81%) thought that it was highly addictive. The results revealed relatively high levels of endorsement for ‘physical and psychological urgent need’ (mean = 43%) and ‘increasing dose’ (mean = 50%), whereas endorsement level for ‘maladaptive use’ was low (mean = 16%). Conclusion Areca nut use (tamul) is of major concern in India and many Southeast Asian countries and its use has been increasing across the globe. The evidence suggests a dependence similar to tobacco use and policy makers need to refine its strategy for control of its use by engaging with multiple stakeholders and adapting it to local context with surveillance and cessation guidelines in order to address this issue.
