Outcome of early detection approach in control of breast, cervical, and oral cancer: Experience from a rural cancer center in India.

In low- and middle-income countries most of the cancer patients attend the hospital at a late stage and treatment completion of these cases is challenging. The early detection program (EDP), in rural areas of Punjab state, India was initiated to identify breast, cervical, and oral cancer at an early stage by raising awareness and providing easy access to diagnosis and treatment. A total of 361 health education programs and 99 early detection clinics were organized. The symptomatic and self-interested (non-symptomatic individuals who opted for screening) cases visited the detection clinic. They were screened for breast, cervical, and/or oral cancer. Further diagnosis and treatment of screen-positive cases were carried out at Homi Bhabha Cancer Hospital (HBCH), Sangrur. Community leaders and healthcare workers were involved in all the activities. The EDP, Sangrur removed barriers between cancer diagnosis and treatment with the help of project staff. From 2019 to 2023, a total of 221,317 populations were covered. Symptomatic and self-interested individuals attended the breast (1627), cervical (1601), and oral (1111) examinations. 46 breast (in situ-4.3%; localized-52.2%), 9 cervical (localized-77.8%), and 12 oral (localized-66.7%) cancer cases were detected, and treatment completion was 82.6%, 77.8%, and 50.0%, respectively. We compared cancer staging and treatment completion of cases detected through EDP with the cases attended HBCH from Sangrur district in 2018; the difference between two groups is statistically significant. Due to the early detection approach, there is disease down-staging and improvement in treatment completion. This approach is feasible and can be implemented to control these cancers in low- and middle-income countries.

Rural-urban disparity in cancer burden and care: findings from an Indian cancer registry.

BACKGROUND: Cancer incidence and mortality vary across the globe, with nearly two-thirds of cancer-related deaths occurring in low- and middle-income countries. The rural-urban disparity in socio-demographic, behavioural, and lifestyle-related factors, as well as in access to cancer care, is one of the contributing factors. Population-based cancer registries serve as a measure for understanding the burden of cancer. We aimed to evaluate the rural-urban disparity in cancer burden and care of patients registered by an Indian population-based cancer registry. METHODS: This study collected data from Varanasi, Uttar Pradesh, India, between 2017 and 2019. Sex and site-specific age-standardised rates for incidence and mortality per 100,000 population were calculated. Rural-urban disparities in cancer incidence and mortality were estimated through rate differences and standardised rate ratios (with 95% confidence intervals). Univariable and multivariable regressions were applied to determine any significant differences in socio-demographic and cancer-related variables according to place of residence (rural/urban). Crude and adjusted odds ratios with 95% confidence intervals were calculated. RESULTS: 6721 cancer patients were registered during the study duration. Urban patients were older and had better literacy and socioeconomic levels, while rural patients had higher odds of having unskilled or semi-skilled professions. Diagnostic and clinical confirmation for cancer was significantly higher in urban patients, while verbal autopsy-based confirmation was higher in rural patients. Rural patients were more likely to receive palliative or alternative systems of medicine, and urban patients had higher chances of treatment completion. Significantly higher incidence and mortality were observed for oral cancer among urban men and for cervical cancer among rural women. Despite the higher incidence of breast cancer in urban women, significantly higher mortality was observed in rural women. CONCLUSIONS: Low- and middle-income countries are facing dual challenges for cancer control and prevention. Their urban populations experience unhealthy lifestyles, while their rural populations lack healthcare accessibility. The distinctness in cancer burden and pattern calls for a re-evaluation of cancer control strategies that are tailor-made with an understanding of urban-rural disparities. Context-specific interventional programmes targeting risk-factor modifications, cancer awareness, early detection, and accessibility to diagnosis and care are essential.

Regional variations and inequalities in testing for early detection of breast and cervical cancer: evidence from a nationally representative survey in India.

BACKGROUND: The burden of cancer in India has been rising, yet testing for early detection remains low. This study explored inequalities in the uptake of breast cancer (BC) examination and cervical cancer (CC) among Indian women, focusing on socioeconomic, regional, and educational differences. METHODS: Data from the 2019-21 National Family Health Survey (n=353,518) were used to assess the uptake of BC examination and CC testing. Inequalities were quantified using the slope index of inequality (SII), relative index of inequality (RII), and relative concentration index (RCI). SII measured absolute inequality, while RII and RCI assessed relative inequality between disadvantaged and advantaged groups. RESULTS: The ever uptake of tests for early detection of BC and CC were low at 9 and 20 per 1,000 women, respectively. Higher uptake was observed among women from the richest households compared to the poorest (SII: 1.1 for BC and 1.8 for CC). The magnitude of relative socioeconomic inequalities was more pronounced in rural areas (RCI: 22.5 for BC and 21.3 for CC) compared to urban areas. Similarly, higher-educated women were 4.84 times (RII: 4.84) and 2.12 times (RII: 2.12) more likely to undergo BC examination and CC testing, respectively, compared to non-educated women. The northeastern region exhibited greater socioeconomic inequality, while the western region showed more education-based inequality. CONCLUSION: The lower uptake of BC examination and CC testing and the marked inequalities underscore the need for targeted interventions to improve access and utilization of testing services, especially among lower-educated women, and those in rural areas.

Role of verbal autopsy in cancer registration: A mixed-methods study from the population-based cancer registry of Northern India.

OBJECTIVES: To describe utilisation of verbal autopsy as one of the data collection approaches in cancer registration in an Indian setting. We aimed to estimate the proportion and epidemiological characteristics of malignancies identified by the Varanasi population-based cancer registry (PBCR) using verbal autopsy between 2017 and 2019 and to develop a thematic network for implementing verbal autopsy. METHODS: This was a cross-sectional mixed-methods study. Quantitative methods were applied to analyse information from PBCR proforma of the verbal autopsy-confirmed cancers; qualitative methods were applied to evaluate verbal autopsy conducted by field staff from key informants. In-depth interviews of field staff for the challenges and potential solutions during verbal autopsy were assessed. RESULTS: Of 6466 registered cancers, 1103 (17.1%) were verbal autopsy-confirmed cancers, which had no other source of information. The majority of verbal autopsy cases were from vulnerable populations who were aged >50 years (721, 65.4%), female (607, 55.1%), from rural backgrounds (853, 77.3%), illiterate or just able to read and write (636, 57.7%), and from lower and middle-income groups (823, 74.6%). Verbal autopsy helped provide information about symptoms and site of disease, diagnostic and treatment details, and disease status. Major challenges during verbal autopsy described by field staff were incomplete cancer treatment, destruction of medical records and non-cooperation by the community and lack of support from the local workforce as cancer is not notifiable. CONCLUSION: Verbal autopsy helped identify cancers that would have been missed during active case finding from available resources. The majority of verbal autopsy-confirmed patients belonged to vulnerable populations. Non-cooperation from community and local health systems was major challenge during verbal autopsy. Developing robust cancer awareness, patient navigation, and social support programmes will strengthen verbal autopsy. Integration of standardised and reproducible methods of verbal autopsy in cancer registry and digitalization of health information, especially in limited-resource settings with weak vital registration, will facilitate completeness in cancer registration.

Overall survival of prostate cancer from Sangrur and Mansa cancer registries of Punjab state, India.

Introduction: There is a scarcity of population-based prostate cancer survival data in India. We assessed the population-based, overall survival of patients with prostate cancer from the Sangrur and Mansa cancer registries of the Punjab state, India. Methods: In the year 2013-2016, a total of 171 prostate cancer cases were registered in these two registries. Based on these registries, survival analysis was performed using the date of diagnosis as the starting date and the last follow-up date being December 31, 2021 or the date of death. Survival was calculated using STATA software. Relative survival was calculated using the Pohar Perme method. Results: Follow up was available for all the registered cases. Of the 171 cases, 41 (24%) were alive and 130 (76.0%) were dead. Of the prescribed treatments, 106 (62.7%) cases completed the treatment and 63 (37.3%) cases did not complete the treatment. Overall, 5-year age-standardized prostate cancer relative survival was 30.3%. Patients who completed the treatment had a 7.8 times higher 5-year relative survival (45.5%) compared to those who did not (5.8%). The difference between the two groups is statistically significant (hazard ratio 0.16, 95% confidence interval [0.10-0.27]). Conclusion: To improve survival, we need to raise awareness in the community and among primary physicians so that prostate cancer cases can reach the hospital early and should be treated effectively. The cancer center should develop the systems in their hospital so that there will be no hurdles to the patients in treatment completion. We found a low overall relative survival among patients of prostate cancer in these two registries. Patients who received treatment had a significantly higher survival.

"Registries are not only a tool for data collection, they are for action": Cancer registration and gaps in data for health equity in six population-based registries in India.

In India, population-based cancer registries (PBCRs) cover less than 15% of the urban and 1% of the rural population. Our study examines practices of registration in PBCRs in India to understand efforts to include rural populations in registries and efforts to measure social inequalities in cancer incidence. We selected a purposive sample of six PBCRs in Maharashtra, Kerala, Punjab and Mizoram and conducted semistructured interviews with staff to understand approaches and challenges to cancer registration, and the sociodemographic information collected by PBCRs. We also conducted a review of peer-reviewed literature utilizing data from PBCRs in India. Findings show that in a context of poor access to cancer diagnosis and treatment and weak death registration, PBCRs have developed additional approaches to cancer registration, including conducting village and home visits to interview cancer patients in rural areas. Challenges included PBCR funding and staff retention, abstraction of data in medical records, address verification and responding to cancer stigma and patient migration. Most PBCRs published estimates of cancer outcomes disaggregated by age, sex and geography. Data on education, marital status, mother tongue and religion were collected, but rarely reported. Two PBCRs collected information on income and occupation and none collected information on caste. Most peer-reviewed studies using PBCR data did not publish estimates of social inequalities in cancer outcomes. Results indicate that collecting and reporting sociodemographic data collected by PBCRs is feasible. Improved PBCR coverage and data will enable India's cancer prevention and control programs to be guided by data on cancer inequities.

Automated versus physician assignment of cause of death for verbal autopsies: randomized trial of 9374 deaths in 117 villages in India.

BACKGROUND: Verbal autopsies with physician assignment of cause of death (COD) are commonly used in settings where medical certification of deaths is uncommon. It remains unanswered if automated algorithms can replace physician assignment. METHODS: We randomized verbal autopsy interviews for deaths in 117 villages in rural India to either physician or automated COD assignment. Twenty-four trained lay (non-medical) surveyors applied the allocated method using a laptop-based electronic system. Two of 25 physicians were allocated randomly to independently code the deaths in the physician assignment arm. Six algorithms (Naïve Bayes Classifier (NBC), King-Lu, InSilicoVA, InSilicoVA-NT, InterVA-4, and SmartVA) coded each death in the automated arm. The primary outcome was concordance with the COD distribution in the standard physician-assigned arm. Four thousand six hundred fifty-one (4651) deaths were allocated to physician (standard), and 4723 to automated arms. RESULTS: The two arms were nearly identical in demographics and key symptom patterns. The average concordances of automated algorithms with the standard were 62%, 56%, and 59% for adult, child, and neonatal deaths, respectively. Automated algorithms showed inconsistent results, even for causes that are relatively easy to identify such as road traffic injuries. Automated algorithms underestimated the number of cancer and suicide deaths in adults and overestimated other injuries in adults and children. Across all ages, average weighted concordance with the standard was 62% (range 79-45%) with the best to worst ranking automated algorithms being InterVA-4, InSilicoVA-NT, InSilicoVA, SmartVA, NBC, and King-Lu. Individual-level sensitivity for causes of adult deaths in the automated arm was low between the algorithms but high between two independent physicians in the physician arm. CONCLUSIONS: While desirable, automated algorithms require further development and rigorous evaluation. Lay reporting of deaths paired with physician COD assignment of verbal autopsies, despite some limitations, remains a practicable method to document the patterns of mortality reliably for unattended deaths.

Clinical breast examination: A screening tool for lower- and middle-income countries.

Breast cancer (BC) remains a global health challenge, devastatingly impacting women's lives. Low-and-middle-income countries (LMIC), such as India, experience a concerning upward trend in BC incidence, necessitating the implementation of cost-effective screening methods. While mammography, ultrasonography, and magnetic resonance imaging are preferred screening modalities in resource-rich settings, limited resources in LMICs make clinical breast examination (CBE) the method of choice. This review explores the merits of CBE, its coverage, barriers, and facilitators in the Indian context for developing strategies in resource-constrained settings. CBE has shown significant down-staging and cost-effectiveness. Performed by trained health workers in minutes, CBE offers an opportunity for education about BC. Various individual and health system barriers, such as stigma, financial constraints, and the absence of opportunistic screening hinder CBE coverage. Promising facilitators include awareness programs, capacity building, and integrating CBE through universal health care. No healthcare provider must miss any screening opportunity through CBE.

Electronic nicotine delivery system: a narrative review on growing threat to tobacco control and health of the young Indian population.

The electronic cigarette (EC) was developed as an alternative to cigarette smoking. In less than a decade, the prevalence of past-month EC usage increased from 1.5 to 27.5 % among US high-school students. In the coming years, Asia-Pacific countries will have the highest sales of electronic nicotine/non-nicotine delivery systems (ENDS/ENNDS) after Western Europe. Based on the World Health Organization and Indian Council of Medical Research recommendations, India approved a complete ban on EC in 2019. Even though it has been three years since the ban, EC is still being sold in India's grey markets, where marketing is not regulated. In this narrative review, we discuss that vaping is not just a harm reduction strategy for tobacco smoking cessation but poses a serious threat to India's existing tobacco control efforts as well as the health of the country's young people.

Quality assessment of a rural population-based cancer registry (PBCR) at Ratnagiri, Maharashtra, India for the years 2017-18.

Background: Cancer registries are valuable resources for cancer control and research. To justify their purpose, their data should be of satisfactory quality by being comparable internationally, complete in their coverage, valid in their values and timely in reporting. This study aimed to assess the quality of the Ratnagiri Population Based Cancer Registry's data for the years 2017-18 across the four dimensions of data quality. Methods: Regarding comparability, the registry procedure was reviewed vis-à-vis the rules they follow for cancer registry operation. We have used four methods for validity: re-abstraction and re-coding, diagnostic criteria methods- like the percentage of microscopically verified (MV%) and of death certificate only (DCO%) cases, missing information like proportion of cases of primary site unknown (PSU%) and internal validity. Semi-quantitative methods were employed for assessing completeness. Timeliness for all years of registry functioning was assessed qualitatively. Results: The overall accuracy rate of the registry was found to be 91.1% (94.7% for demographic and 88% for tumour details). Mortality to incidence ratios were found to be 0.50 for females and 0.59 for males. MV% was found to be 90.8% for males and 91.5% for females. The average number of sources per case was found to be 1.5. DCO% was found to be 2.7%. PSU% was 7.4%. Conclusion: We have positive results regarding the data's validity and comparability, but there is scope for improvement concerning completeness. Continuous training of the registry personnel and monitoring of the registry is recommended.

A Glimpse into the Epidemiology of Geriatric Cancers in India: Report from the Indian Population Based Cancer Registries.

INTRODUCTION: Indian population is aging and the cancer rates are rising.  Older adults (OAs)(≥60 years) with cancer require specialized care.  However, data on geriatric cancer epidemiology is scarce. METHODS: The study compiled the geriatric cancer data from the published reports(2012-2014) of Indian population-based cancer registries(PBCRs). RESULTS: Of the 1,61,363 cancers registered in the Indian PBCRs, 72,446(44.9%) occur in OAs, with  21,805(30.1%), 18,349(25.3%), 14,645(20.2%), and 17,647(24.4%) occurring in 60-64, 65-69, 70-74, and ≥75year age groups.  The truncated incidence rates for OAs are 555.9,404.5, and 481.9 for males, females, and OA populations respectively.  The common cancers are lung, prostate, and esophagus cancers in males, breast, cervix, and lung in females.  The overall common cancers are lung, prostate, and breast.  While  >50% of the incident cases of prostate, and bladder cancers occurred in OAs, <20% of Hodgkin lymphoma and thyroid cancers occurred in OAs. OA cancer epidemiology has a regional variation, highest in South India and lowest in Western India. CONCLUSION: The current study quantifies the cancer burden in the Indian geriatric population. Understanding the epidemiology of geriatric cancers is vital to health program planning and implementation. Increased awareness, focused resource allocation, research, and national policies for streamlining care will all help to improve geriatric cancer outcomes.

Burden of tobacco-related cancers in urban, semi-urban and rural setting of Nepal: Findings from population-based cancer registries 2019.

BACKGROUND: Nepal is one of the high prevalent countries for tobacco use in Southeast Asia regions. Tobacco related cancer share the major burden since a decade, however, population-based estimates is still lacking. This study provides results from population-based cancer registries on tobacco-related cancer (TRCs) burden in Nepal. METHODS: The data were collected by population-based cancer registry conducted in nine districts by Nepal Health Research Council. The districts were categorized in urban, semi-urban and rural regions on the basis of geographical locations and facilities available in the regions. Analysis was done to identify tobacco-associated cancer incidence, mortality and patterns along with cumulative risk of having cancer before the age of 75 years. RESULTS: Tobacco-related cancer was 35.3% in men and 17.3% in women. We found that every one in 36 men and one in 65 women developed tobacco-related cancer before age 75 in Nepal. Cancer of lung, mouth, esophagus and larynx were among the five most common tobacco-related cancers in both men and women. The incidence of tobacco-associated cancers was higher in urban region with age adjusted rate 33.6 and 17.0 per 100,000 population for men and women respectively compared to semi-urban and rural regions. Tobacco-associated cancer mortality was significantly higher compared to incidence. CONCLUSION: The prevalence of tobacco-related cancer found high in Nepal despite of enforcement of tobacco control policy and strategies including WHO framework convention on tobacco control. Concerned authorities should focus towards monitoring of implemented tobacco control policy and strategies.

Uniqueness of lung cancer in Southeast Asia.

Lung cancer varies between Caucasians and Asians. There have been differences recorded in the epidemiology, genomics, standard therapies and outcomes, with variations according to the geography and ethnicity which affect the decision for optimal treatment of the patients. To better understand the profile of lung cancer in Southeast Asia, with a focus on India, we have comprehensively reviewed the available data, and discuss the challenges and the way forward. A substantial proportion of patients with lung cancer in Southeast Asia are neversmokers, and adenocarcinoma is the common histopathologic subtype, found in approximately a third of the patients. EGFR mutations are noted in 23-30% of patients, and ALK rearrangements are noted in 5-7%. Therapies are similar to global standards, although access to newer modalities and molecules is a challenge. Collaborative research, political will with various policy changes and patient advocacy are urgently needed.

Evaluation of Medical Certification of Cause of Death in Tertiary Cancer Hospitals in Northern India.

BACKGROUND: Medical certification of cause of death (MCCD) provides valuable data regarding disease burden in a community and for formulating health policy. Inaccurate MCCDs can significantly impair the precision of national health information. OBJECTIVE: To evaluate the accuracy of cause of death certificates prepared at two tertiary cancer care hospitals in Northern India during the study period (May 2018 to December 2020). METHOD: A retrospective observational study at two tertiary cancer care hospitals in Varanasi, India, over a period of two and a half years. Medical records and cause of death certificates of all decedents were examined. Demographic characteristics, administrative details and cause of death data were collected using the WHO recommended death certificates. Accuracy of death certification was validated by electronic medical records and errors were graded. RESULTS: A total of 778 deaths occurred in the two centres during the study period. Of these, only 30 (3.9%) certificates were error-free; 591 (75.9%) certificates had an inappropriate immediate cause of death; 231 (29.7%) certificates had incorrectly labelled modes of death as the immediate cause of death; and 585 (75.2%) certificates had an incorrect underlying cause of death. The majority of certificates were prepared by junior doctors and were significantly associated with higher certification errors. CONCLUSION: A high rate of errors was identified in death certification at the cancer care hospitals during the study period. Inaccurate MCCDs related to cancers can potentially influence cancer statistics and thereby affect policy making for cancer control. IMPLICATIONS: This study has identified the pressing need for appropriate interventions to improve quality of certification through training of doctors.

Pediatric Cancer Burden in Different Regions of India: Analysis of Published Data From 33 Population-Based Cancer Registries.

OBJECTIVE: To provide the regional pediatric cancer (age-group 0-14 years) burden and pattern in India utilizing published data of population-based cancer registries established under the National Cancer Registry Programme and Tata Memorial Centre, Mumbai. METHODS: Based on the geographic locations, the population-based cancer registries were categorized into six regions. The age-specific incidence rate was calculated using the number of pediatric cancer cases and population in the respective age-group. Age-standardized incidence rate per million and 95% CI were calculated. RESULTS: In India, 2% of all cases were pediatric cancer. The age-standardized incidence rate (95% CI) for boys and girls is 95.1 (94.3-95.9) and 65.5 (64.8-66.2) per million population, respectively. Registries from northern India reported the highest rate; while the lowest rate was in northeastern India. CONCLUSIONS: There is a need to establish pediatric cancer registries in different regions of India to know the accurate pediatric cancer burden.
