RESUMO

This paper outlines the impact of the COVID-19 pandemic on cancer services in the UK including screening, symptomatic diagnosis, treatment pathways and projections on clinical outcomes as a result of these care disruptions. A restoration of cancer services to pre-pandemic levels is not likely to mitigate this adverse impact, particularly with an ageing population and increased cancer burden. New cancer cases are projected to rise to over 500,000 per year by 2035, with over 4 million people living with and beyond cancer. This paper calls for a strategic transformation to prioritise effort on the basis of available datasets and evidence-in particular, to prioritise cancers where an earlier diagnosis is feasible and clinically useful with a focus on mortality benefit by preventing emergency presentations by harnessing data and analytics. This could be delivered by a focus on underperforming groups/areas to try and reduce inequity, linking near real-time datasets with clinical decision support systems at the primary and secondary care levels, promoting the use of novel technologies to improve patient uptake of services, screening and diagnosis, and finally, upskilling and cross-skilling healthcare workers to expand supply of diagnostic and screening services.

RESUMO

BACKGROUND: This national study investigated hospital quality and patient factors associated with treatment location for breast cancer surgery. METHODS: By using linked administrative data sets from the English National Health Service, the authors identified all women diagnosed between January 2, 2016, and December 31, 2018, who underwent breast-conserving surgery (BCS) or a mastectomy with or without immediate breast reconstruction. The extent to which patients bypassed their nearest hospital was investigated using a geographic information system (ArcGIS). Conditional logistic regressions were used to estimate the impact of travel time, hospital quality, and patient characteristics. RESULTS: 22,622 Of 69,153 patients undergoing BCS, 22,622 (32.7%) bypassed their nearest hospital; and, of 23,536 patients undergoing mastectomy, 7179 (30.5%) bypassed their nearest hospital. Women who were younger, without comorbidities, or from rural areas were more likely to travel to more distant hospitals (p < .05). Patients undergoing BCS (odds ratio [OR], 1.85; 95% confidence interval [CI], 1.36-2.50) or mastectomy (OR, 1.52; 95% CI, 1.14-2.02) were more likely to be treated at specialist breast reconstruction centers despite not undergoing the procedure. Patients receiving mastectomy and immediate breast reconstruction were more likely to travel to hospitals employing surgeons who had a media reputation (OR, 2.41; 95% CI, 1.28-4.52). Patients undergoing BCS were less likely to travel to hospitals with shorter surgical waiting times (OR, 0.65; 95% CI, 0.46-0.92). The authors did not observe a significant impact for research activity, hospital quality rating, breast re-excision rates, or the status as a multidisciplinary cancer center. CONCLUSIONS: Patient choice policies may drive inequalities in the health care system without improving patient outcomes.

RESUMO

BACKGROUND: Following referral for investigation of urgent suspected cancer within the English National Health Service referral system, 7% of referred individuals are diagnosed with cancer. This study aimed to investigate the risk of cancer occurrence within 1-5 years of finding no cancer following an urgent suspected cancer referral. METHODS: This national cohort study used urgent suspected cancer referral data for England from the Cancer Waiting Times dataset and linked it with cancer diagnosis data from the National Cancer Registration dataset. Data were extracted for the eight most commonly referred to urgent suspected cancer referral pathways (breast, gynaecological, head and neck, lower and upper gastrointestinal, lung, skin, and urological) for the period April 1, 2013, to March 31, 2014, with 5-year follow-up for individuals with no cancer diagnosis within 1 year of referral. The primary objective was to investigate the occurrence and type of subsequent cancer in years 1-5 following an urgent suspected cancer referral when no cancer was initially found, both overall and for each of the eight referral pathways. The numbers of subsequent cancers were compared with expected cancer incidence in years 1-5 following referral, using standardised incidence ratios (SIRs) based on matched age-gender distributions of expected cancer incidence in England for the same time period. The analysis was repeated, stratifying by referral group, and by calculating the absolute and expected rate of all cancers and of the same individual cancer as the initial referral. FINDINGS: Among 1·18 million referrals without a cancer diagnosis in years 0-1, there were 63 112 subsequent cancers diagnosed 1-5 years post-referral, giving an absolute rate of 1338 (95% CI 1327-1348) cancers per 100 000 referrals per year (1038 [1027-1050] in females, 1888 [1867-1909] in males), compared with an expected rate of 1054 (1045-1064) cancers per 100 000 referrals per year (SIR 1·27 [95% CI 1·26-1·28]). The absolute rate of any subsequent cancer diagnosis 1-5 years after referral was lowest following suspected breast cancer referral (746 [728-763] cancers per 100 000 referrals per year) and highest following suspected urological (2110 [2070-2150]) or lung cancer (1835 [1767-1906]) referral. For diagnosis of the same cancer as the initial referral pathway, the highest absolute rates were for the urological and lung pathways (1011 [984-1039] and 638 [598-680] cancers per 100 000 referrals per year, respectively). The highest relative risks of subsequent diagnosis of the same cancer as the initial referral pathway were for the head and neck pathway (SIR 3·49 [95% CI 3·22-3·78]) and lung pathway (3·00 [2·82-3·20]). INTERPRETATION: Cancer risk was higher than expected in the 5 years following an urgent suspected cancer referral. The potential for targeted interventions, such as proactive monitoring, safety-netting, and cancer awareness or risk reduction initiatives should be investigated. FUNDING: Cancer Research UK.

RESUMO

Around 25% of women undergoing Axillary Clearance (ANC) develop lymphedema (LE). Intervention with a compression garment is recommended to prevent LE but no randomised evidence exists to support this strategy. METHODS: A randomised trial tested standard management versus application of graduated compression garments (20-24 mmHg) to affected arm, for 1 year. Women with node positive breast cancer (n = 1300) undergoing ANC consented to arm volume measurements and those developing a 4-9% relative arm volume increase (RAVI) (subclinical LE) within 9 months post-surgery were randomised. Primary outcome was proportion of patients developing LE (RAVI > 10%) by 24-months in each group. Secondary endpoints included Quality of life in each group. RESULTS: In total 143 patients were randomised (74 no sleeve: 69 compression sleeve) between October 2010 and November 2015. The lymphoedema rate at 24 months in the 'no sleeve' group was at 41%, similar to the 'sleeve' group (30%: p = 0.32). Thirtytwo patients randomised to the 'no sleeve' group had a sleeve applied within 24 months. Body Mass Index (BMI) at randomisation predicted LE at any time point HR 1.04 (CI 1.01-1.08; p = 0.01). Patients with obesity (BMI > 30) had higher rates of LE in both groups (46%) compared to those with BMI < 30 (24%). No difference between patients was found in either group in changes in QoL. Compression sleeves applied after development of LE improved QoL scores (FACT-B p = 0.007:TOI p = 0.042). CONCLUSION: Early intervention with External Compression garments does not prevent clinical LE, particularly in women with a high BMI > 30. The use of prophylactic garments in subclinical LE (RAVI < 9%) is unwarranted.

RESUMO

PURPOSE: South Asian Association for Regional Cooperation (SAARC) nations are a group of eight countries with low to medium Human Development Index values. They lack trained human resources in primary health care to achieve the WHO-stated goal of Universal Health Coverage. An unregulated service sector of informal health care providers (IPs) has been serving these underserved communities. The aim is to summarize the role of IPs in primary cancer care, compare quality with formal providers, quantify distribution in urban and rural settings, and present the socioeconomic milieu that sustains their existence. METHODS: A narrative review of the published literature in English from January 2000 to December 2021 was performed using MeSH Terms Informal Health Care Provider/Informal Provider and Primary Health Care across databases such as Medline (PubMed), Google Scholar, and Cochrane database of systematic reviews, as well as World Bank, Center for Global Development, American Economic Review, Journal Storage, and Web of Science. In addition, citation lists from the primary articles, gray literature in English, and policy blogs were included. We present a descriptive overview of our findings as applicable to SAARC. RESULTS: IPs across the rural landscape often comprise more than 75% of primary caregivers. They provide accessible and affordable, but often substandard quality of care. However, their network would be suitable for prompt cancer referrals. Care delivery and accountability correlate with prevalent standards of formal health care. CONCLUSION: Acknowledgment and upskilling of IPs could be a cost-effective bridge toward universal health coverage and early cancer diagnosis in SAARC nations, whereas state capacity for training formal health care providers is ramped up simultaneously. This must be achieved without compromising investment in the critical resource of qualified doctors and allied health professionals who form the core of the rural public primary health care system.

RESUMO

Introduction: COVID-19 pandemic has caused major disruptions to delivery of various cancer care services as efforts were put to control the outbreak of the pandemic. Although the pandemic has highlighted the inadequacies of the system but has also led to emergence of a new cancer care delivery model which relies heavily on digital mediums. Digital health is not only restricted to virtual dissemination of information and consultation but has provided additional benefits ranging from support to cancer screening, early and more accurate diagnosis to increasing access to specialized care. This paper evaluates the challenges in the adoption of digital technologies to deliver cancer care services and provides recommendation for large-scale adoption in the Indian healthcare context. Methods: We performed a search of PubMed and Google Scholar for numerous terms related to adoption of digital health technologies for cancer care during pandemic. We also analyze various socio-ecological challenges-from individual to community, provider and systematic level-for digital adoption of cancer care service which have existed prior to pandemic and lead to digital inequalities. Results: Despite encouraging benefits accruing from the adoption of digital health key challenges remain for large scale adoption. With respect to user the socio-economic characteristics such as age, literacy and socio-cultural norms are the major barriers. The key challenges faced by providers include regulatory issues, data security and the inconvenience associated with transition to a new system. Policy Summary: For equitable digital healthcare, the need is to have a participatory approach of all stakeholders and urgently addressing the digital divide adequately. Sharing of health data of public and private hospitals, within the framework of the Indian regulations and Data Protection Act, is critical to the development of digital health in India and it can go a long way in better forecasting and managing cancer burden.

RESUMO

BACKGROUND: The COVID-19 pandemic has been highly disruptive for cancer care. Here, we examined the effect COVID-19 had on performance of the 62-day Cancer Waiting Time (CWT) target set by the National Health Service (NHS) in England. METHODS: Data were retrospectively obtained on COVID-19 hospitalisations and CWT for NHS hospitals in England (n = 121). We produced a 'COVID-19 burden' to describe the proportion of each provider's beds occupied with COVID-19 patients. COVID-19 burden was examined against CWT performance for 1st April - 30th May 2020 (Wave 1), and 1st October - 30th November 2020 (Wave 2). Two-tailed Spearman correlations were used to identify relationships between COVID-19 burden and CWT performance amongst different referral (i.e., 2-week-wait (2 W W) and internal specialist) and tumour types. Significantly correlated variables were further examined using linear regression models. RESULTS: COVID-19 burden was negatively associated with the percentage of 2 W W pathway referrals that met the CWT target in Wave 1 (r= -0.30, p = 0.001) and Wave 2 (r= -0.21, p = 0.02). These associations were supported by the results from our linear regression models (B for wave 1: -0.71; 95 %CI: -1.03 to -0.40; B for wave 2: -0.38; 95 %CI: -0.68 to -0.07). No associations were found between COVID-19 burden and internal specialist referrals or tumour type. CONCLUSION: Increased COVID-19 burden was associated with lower compliance with CWT targets amongst urgent referrals from primary care in England. This will likely be an ongoing issue due to the backlog of patients awaiting investigations and treatment. POLICY SUMMARY: As the number of cancer referrals improve, we highlight the need for changes to primary and secondary care to manage the backlog within cancer diagnostic services to alleviate the impact of COVID-19.

RESUMO

DNA methylation is aberrant in cancer, but the dynamics, regulatory role and clinical implications of such epigenetic changes are still poorly understood. Here, reduced representation bisulfite sequencing (RRBS) profiles of 1538 breast tumors and 244 normal breast tissues from the METABRIC cohort are reported, facilitating detailed analysis of DNA methylation within a rich context of genomic, transcriptional, and clinical data. Tumor methylation from immune and stromal signatures are deconvoluted leading to the discovery of a tumor replication-linked clock with genome-wide methylation loss in non-CpG island sites. Unexpectedly, methylation in most tumor CpG islands follows two replication-independent processes of gain (MG) or loss (ML) that we term epigenomic instability. Epigenomic instability is correlated with tumor grade and stage, TP53 mutations and poorer prognosis. After controlling for these global trans-acting trends, as well as for X-linked dosage compensation effects, cis-specific methylation and expression correlations are uncovered at hundreds of promoters and over a thousand distal elements. Some of these targeted known tumor suppressors and oncogenes. In conclusion, this study demonstrates that global epigenetic instability can erode cancer methylomes and expose them to localized methylation aberrations in-cis resulting in transcriptional changes seen in tumors.

RESUMO

Outcomes from breast cancer for women in the UK have improved significantly over recent decades. These gains are largely attributable to a combination of earlier diagnosis and access to treatments delivered to patients by the National Health Service irrespective of cost. Ethnic minority groups make up almost fifteen percent of the UK population and there is concern however that these groups may have poorer outcomes from the disease. In this short report we seek to summarise what the current evidence tells us about the patterns of breast cancer incidence and outcomes in ethnic minority women in the UK in order to raise awareness about this topic and provide consideration for what future research is needed to address the gaps that may exist.

RESUMO

Low-income and middle-income countries (LMICs) have a disproportionately high burden of cancer and cancer mortality. The unique barriers to optimum cancer care in these regions necessitate context-specific research. The conduct of research in LMICs has several challenges, not least of which is a paucity of formal training in research methods. Building capacity by training early career researchers is essential to improve research output and cancer outcomes in LMICs. The International Collaboration for Research methods Development in Oncology (CReDO) workshop is an initiative by the Tata Memorial Centre and the National Cancer Grid of India to address gaps in research training and increase capacity in oncology research. Since 2015, there have been five CReDO workshops, which have trained more than 250 oncologists from India and other countries in clinical research methods and protocol development. Participants from all oncology and allied fields were represented at these workshops. Protocols developed included clinical trials, comparative effectiveness studies, health services research, and observational studies, and many of these protocols were particularly relevant to cancer management in LMICs. A follow-up of these participants in 2020 elicited an 88% response rate and showed that 42% of participants had made progress with their CReDO protocols, and 73% had initiated other research protocols and published papers. In this Policy Review, we describe the challenges to research in LMICs, as well as the evolution, structure, and impact of CReDO and other similar workshops on global oncology research.

RESUMO

The level of stromal tumor-infiltrating lymphocytes (sTILs) in triple-negative (TNBC) and HER2-positive breast cancers convey prognostic information. The importance of systemic immunity to local immunity is unknown in breast cancer. We previously demonstrated that histological alterations in axillary lymph nodes (LNs) carry clinical relevance. Here, we capture local immune responses by scoring TILs at the primary tumor and systemic immune responses by recording the formation of secondary follicles, also known as germinal centers, in 2,857 cancer-free and involved axillary LNs on haematoxylin and eosin (H&E) stained sections from a retrospective cohort of 161 LN-positive triple-negative and HER2-positive breast cancer patients. Our data demonstrate that the number of germinal center formations across all cancer-free LNs, similar to high levels of TILs, is associated with a good prognosis in low TILs TNBC. This highlights the importance of assessing both primary and LN immune responses for prognostication and for future breast cancer research.

RESUMO

INTRODUCTION: Delays in cancer diagnosis arose from the commencement of non-pharmaceutical interventions (NPI) introduced in the UK in March 2020 in response to the COVID-19 pandemic. Our earlier work predicted this will lead to approximately 3620 avoidable deaths for four major tumour types (breast, bowel, lung, and oesophageal cancer) in the next 5 years. Here, using national population-based modelling, we estimate the health and economic losses resulting from these avoidable cancer deaths. We also compare these with the impact of an equivalent number of COVID-19 deaths to understand the welfare consequences of the different health conditions. METHODS: We estimate health losses using quality-adjusted life years (QALYs) and lost economic productivity using the human capital (HC) approach. The analysis uses linked English National Health Service (NHS) cancer registration and hospital administrative datasets for patients aged 15-84 years, diagnosed with breast, colorectal, and oesophageal cancer between 1st Jan to 31st Dec 2010, with follow-up data until 31st Dec 2014, and diagnosed with lung cancer between 1st Jan to 31st Dec 31 2012, with follow-up data until 31st Dec 2015. Productivity losses are based on the estimation of excess additional deaths due to cancer at 1, 3 and 5 years for the four cancer types, which were derived from a previous analysis using this dataset. A total of 500 random samples drawn from the total number of COVID-19 deaths reported by the Office for National Statistics, stratified by gender, were used to estimate productivity losses for an equivalent number of deaths (n = 3620) due to SARS-CoV-2 infection. RESULTS: We collected data for 32,583 patients with breast cancer, 24,975 with colorectal cancer, 6744 with oesophageal cancer, and 29,305 with lung cancer. We estimate that across the four site-specific cancers combined in England alone, additional excess cancer deaths would amount to a loss of 32,700 QALYs (95% CI 31,300-34,100) and productivity losses of £103.8million GBP (73.2-132.2) in the next five years. For breast cancer, we estimate a loss of 4100 QALYS (3900-4400) and productivity losses of £23.2 m (18.2-28.6); for colorectal cancer, 15,000 QALYS (14,100-16,000) lost and productivity losses of £35.7 m (22.4-48.7); for lung cancer 10,900 QALYS (9,900-11,700) lost and productivity losses of £38.3 m (14.0-59.9) for lung cancer; and for oesophageal cancer, 2700 QALYS (2300-3,100) lost and productivity losses of £6.6 m (-6 to -17.6). In comparison, the equivalent number of COVID-19 deaths caused approximately 21,450 QALYs lost, as well as productivity losses amounting to £76.4 m (73.5-79.2). CONCLUSION: Premature cancer deaths resulting from diagnostic delays during the first wave of the COVID-19 pandemic in the UK will result in significant economic losses. On a per-capita basis, this impact is, in fact, greater than that of deaths directly attributable to COVID-19. These results emphasise the importance of robust evaluation of the trade-offs of the wider health, welfare and economic effects of NPI to support both resource allocation and the prioritisation of time-critical health services directly impacted in a pandemic, such as cancer care.

RESUMO

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.

RESUMO

INTRODUCTION: In women undergoing breast-conserving surgery (BCS), 20-25% require a re-operation as a result of incomplete tumour resection. An intra-operative technique to assess tumour margins accurately would be a major advantage. A novel method for intraoperative margin assessment was developed by applying a thin flexible scintillating film to specimens-flexible autoradiography (FAR) imaging. A single-arm, multi-centre study was conducted to evaluate the feasibility of intraoperative [18F]FDG FAR for the assessment of tumour margins in BCS. METHODS: Eighty-eight patients with invasive breast cancer undergoing BCS received ≤ 300 MBq of [18F]FDG 60-180 min pre-operatively. Following surgical excision, intraoperative FAR imaging was performed using the LightPath® Imaging System. The first 16 patients were familiarisation patients; the remaining 72 patients were entered into the main study. FAR images were analysed post-operatively by three independent readers. Areas of increased signal intensity were marked, mean normalised radiances and tumour-to-tissue background (TBR) determined, agreement between histopathological margin status and FAR assessed and radiation dose to operating theatre staff measured. Subgroup analyses were performed for various covariates, with thresholds set based on ROC curves. RESULTS: Data analysis was performed on 66 patients. Intraoperative margin assessment using FAR was completed on 385 margins with 46.2% sensitivity, 81.7% specificity, 8.1% PPV, 97.7% NPV and an overall accuracy of 80.5%, detecting both invasive carcinoma and DCIS. A subgroup analysis based on [18F]FDG activity present at time of imaging revealed an increased sensitivity (71.4%), PPV (9.3%) and NPV (98.4%) in the high-activity cohort with mean tumour radiance and TBR of 126.7 ± 45.7 photons/s/cm2/sr/MBq and 2.1 ± 0.5, respectively. Staff radiation exposure was low (38.2 ± 38.1 µSv). CONCLUSION: [18F]FDG FAR is a feasible and safe technique for intraoperative tumour margin assessment. Further improvements in diagnostic performance require optimising the method for scintillator positioning and/or the use of targeted radiopharmaceuticals. TRIAL REGISTRATION: Identifier: NCT02666079.

RESUMO

One of the most ignored aspects of the COVID-19 pandemic has been the impact of public health measures by governments on wider health and welfare. From March 2020, hospitals in the UK saw a dramatic reduction in patients with cancer presenting due to multifactorial reasons. The impact of the pandemic on patients with cancer in the South East London Cancer Alliance was studied. The specific aims were (1) to examine the reduction in cancer diagnoses during the first wave of the pandemic and (2) to examine the stage of diagnosis of patients with cancer presenting during the pandemic compared with that of patients presenting before the pandemic. There was an 18.2% reduction in new cancer diagnoses (an estimate of 987 cancers), when compared with 2019. This fall in cancer diagnoses was most marked in patients with prostate (51.4%), gynaecological (29.7%), breast (29.5%) and lung (23.4%) cancers. There was an overall 3.9% increase in advanced stage presentation (Stages 3 and 4), with an overall 6.8% increase in Stage 4 cancers during this period. The greatest shifts were seen in lung (increase of 6.3%, with an 11.2% increase in Stage 4 cancer alone) and colorectal (5.4%) cancers. For prostate cancer, there was an increase in 3.8% in those presenting with Stage 4 disease. For breast cancer, there was an 8% reduction in patients diagnosed with Stage 1 cancer with commensurate increases in the proportion of those with Stage 2 disease. The experiences in cancer are a salient warning that pandemic control measures and policy need to balance all health and welfare. Alternative strategies need to be adopted during further waves of the current and any future pandemic to ensure that patients with cancer are prioritised for diagnosis and treatment to prevent late-stage presentation and an increase in avoidable deaths.

RESUMO

BACKGROUND: Adolescence is an influential stage in students' lives when lifelong behaviours such as tobacco use are formed. During these years, school teachers are important role models for tobacco control among students. A study was conducted among school personnel and administrators to understand the key drivers for implementing an evidence-based school tobacco control program. METHODOLOGY: A cross-sectional, mixed-method study was conducted in five districts of Assam, India. The quantitative study was conducted among 565 school personnel across 40 Government-aided schools. Data was collected by means of an anonymous, self-administered questionnaire. Qualitative data was generated from 15 focus group discussions (FGDs) among 146 participants - District Program Officers, Block Education Officers, Cluster Coordinators, Headmasters and Teachers. RESULTS: While the prevalence of smoked tobacco was low (3%), the use of smokeless tobacco was higher (40%), and the prevalence of use of areca nut without tobacco (65%) was still higher among school personnel. They were aware of the school policies prohibiting the use of tobacco among students within or outside school buildings or during school-sponsored activities (81%); they had rather limited knowledge about policy for themselves (58%). There was lack of access to training materials about prevention of tobacco use among youth. The FGDs amongst school personnel resulted in several constructive suggestions on tobacco control in schools mainly in training school teachers, monitoring the program and incentives for execution of the program. However, there was a reluctance to implement a smokeless tobacco control programme since many were current users of smokeless tobacco and areca nut. CONCLUSION: Tobacco control policies as well as training school personnel in schools need to improve and further measures must be taken to prohibit use of areca nut, which contains carcinogens. The existing system of the education department can be utilised to implement tobacco control programmes effectively.

RESUMO

BACKGROUND: Access to palliative care within healthcare systems of low- and middle-income countries (LMICs) has never been more pronounced than in current times. The Lancet Commission Report (2018) estimates that 80% of global serious health-related suffering (SHS), which demands access to palliative care for its relief, are in LMICs. Cancer is a major contributor to SHS and a rapidly growing burden in LMICs. Similar to many LMICs, cancer is a leading cause of death in India. The North-East Region (NER) of India has a high prevalence of cancer and paucity of services for cancer and palliative care. OBJECTIVES: To describe the strategies used to initiate and strengthen palliative care services integrated with the comprehensive cancer care initiatives in the state of Assam in NER. METHODS: After an initial assessment of the status of palliative care in the NER, a multipronged strategy was adopted that aligned with the WHO framework recommended for initiating palliative care services. A core team working with a government and private collaborative strategized and activated supportive policies, education, and training and improved access and availability to essential drugs, while implementing the components synchronously within the state. SIGNIFICANCE: This project demonstrates an informed regional adaptation of the WHO model. It highlights the strengths of integrating palliative care within cancer care program right from its inception. It emphasizes the sustainability of services activated across public healthcare systems, as compared with the donor- or champion-driven initiatives. The outcome of this project underlines the relevance of this model for LMIC regions with similar health systems and sociocultural and economic contexts.

RESUMO

BACKGROUND: Cancer patients' experience is dependent on the complex interaction between the patient, carer, healthcare practitioners and healthcare system. The aim of the study was to assess the experience of cancer patients in Assam in order to identify potential areas for improvement in delivering high quality cancer care. METHODS: A cross sectional patient experience survey was conducted in 400 patients using structured interviews and pre-tested questionnaires that collected patient-reported outcomes including access to cancer care, experience while availing cancer services across the pathway, waiting times, communication and counselling support, out-of-pocket expenditure and advice regarding available insurance schemes and financial support. RESULTS: The cancer patient's experience of accessing healthcare in Assam is variable with principal challenges being financial constraint and geographical distance to healthcare facilities. Overall, patients' experience during registration, first consultation, pre-treatment and during treatment was good with high satisfaction rates expressed in several of the areas assessed. Areas that were identified for improvement were better explanation of long-term side effects of treatment, enhanced guidance in choosing treatment options and greater support from healthcare professionals to help patients cope with the psychological, emotional and physical aspects of their cancer diagnosis, treatment and recovery. CONCLUSION: Understanding cancer patient experiences across their journey is critical to delivering accessible and affordable care. Effective, adaptive and responsive communication remains the anchor of excellent patient-centred care especially in resource constraint settings. POLICY STATEMENT: The paper provides an insight into critical areas focusing on diagnosis, treatment, continuum of care and communication during cancer patients' care in India. Healthcare policy needs to focus on developing a robust, holistic, healthcare system in terms of accessibility, affordability and psychosocial care, including counselling and financial support, to ensure better cancer outcomes.
