RESUMEN
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.
RESUMEN
Radiotherapy (RT) and immunotherapy (IT) are the powerful tools for cancer treatment which act through the stimulation of immune response, and evidence suggest that combinatorial actions of these therapies may augment each other's beneficial effect through complex synergistic mechanisms. These molecular strategies are designed to target rapidly dividing cancer cells by either directly or indirectly inducing DNA damage. However, when cells detect DNA damage, they activate a range of signalling pathways known as the DNA damage response (DDR) to repair. Strategies are being developed to interfere with the DDR pathways in cancer cells to ensure their damage-induced degeneration. The stability of a cell's genetic material is largely dependent on the efficacy of DNA repair and therefore, an in-depth understanding of DNA damages and repair mechanism(s) in cancer cells is important to develop a promising therapeutic strategies for ensuring the efficacy of damage-induced tumor cell death. In recent years, a wide range of small molecule drugs have been developed which are currently being employed to combat the DNA repair deficiencies associated with tumor cells. Sequential or concurrent use of these two modalities significantly enhances the anti-tumor response, however with a concurrent probability of increased incidence of symptomatic adverse effects. With advent of newer IT agents, and administration of higher doses of radiation per fraction, such effects are more difficult to predict owing to the paucity of randomized trial data. It is well established that anti cytotoxic-T-lymphocyte-associated antigen 4 (CTLA-4), anti- Programmed cell death protein 1(PD-1), anti-Programmed cell death one ligand 1 (PD-L1) can be safely administered with RT and many studies have demonstrated survival benefit with such combination for patients with metastatic malignancy. However, the biology of radioimmunotherapy (RT/IT) is still an open area where research need to be focused to determine optimum dosage specially the interaction of the RT/IT pathways to determine optimum dosing schedule. In the current article we have summarised the possible intracellular immunological events that might be triggered when RT and IT modalities are combined with the DDR antagonists and highlighted present clinical practices, outcome, and toxicity profile of this novel treatment strategy.
RESUMEN
Executing global clinical trials for cancer is a long, expensive, and complex undertaking. While selecting countries global studies, sponsors must consider several aspects including patient pool, quality of trained investigators, competing trials, availability of infrastructure, and financial investment versus returns. With a large, often treatment-naïve, and diverse patient pool, relatively low cost, good quality health care facilities in urban areas, and a robust and well-trained workforce, India offers several advantages for conducting oncology clinical trials. However, there remains challenges, including a shifting regulatory environment in recent decades. With the implementation of the New Drugs and Clinical Trial Rules in 2019, India's regulatory atmosphere seems to have stabilized. In this article, we present a review of the evolving clinical trial landscape in India, highlight the current regulatory scenario, and discuss the advantages and challenges of selecting India as a potential location for conducting global oncology clinical trials.

This paper outlines the process undertaken by Asian National Cancer Centers Alliance (ANCCA) members in working towards an Asian Code Against Cancer (ACAC). The process involves: (i) identification of the criteria for selecting the existing set of national recommendations for ACAC (ii) compilation of existing national codes or recommendations on cancer prevention (iii) reviewing the scientific evidence on cancer risk factors in Asia and (iv) establishment of one or more ACAC under the World Code Against Cancer Framework. A matrix of national codes or key recommendations against cancer in ANCCA member countries is presented. These include taking actions to prevent or control tobacco consumption, obesity, unhealthy diet, physical inactivity, alcohol consumption, exposure to occupational and environmental toxins; and to promote breastfeeding, vaccination against infectious agents and cancer screening. ANCCA will continue to serve as a supportive platform for collaboration, development, and advocacy of an ACAC jointly with the International Agency for Research on Cancer/World Health Organization (IARC/WHO).
RESUMEN
QDs are semiconductor nanocrystalline materials with distinct optical and electronic characteristics due to their microscopic size and quantum mechanical properties. They are often composed of materials such as cadmium selenide (CdSe), cadmium telluride (CdTe), or indium phosphide (InP) and are typically in the size range of 2 to 10 nanometers in diameter. These tiny particles are used in various scientific and technological applications. Some key characteristics and applications of quantum dots are size-dependent Optical Properties with tunable emission. The color of light emitted by quantum dots highly depends on their size. Smaller QDs emit blue or green light, while larger ones emit red or near-infrared light. This tunability makes them valuable in various applications, especially in molecular medicine and oncology research. Quantum dots can exhibit a high quantum yield, meaning they efficiently emit light when excited, making them excellent fluorescent probes for non-invasive imaging. This review discusses the applications of QDs and their role in biomedical research and patient care, focusing on non-invasive imaging and preventive oncology.

Cardiovascular diseases (CVD) remain a major global health challenge, with an escalating impact on mortality despite advancements in managing conventional risk factors. This review investigates the intricate relationship between human papillomavirus (HPV) and CVD, shedding light on a novel aspect of cardiovascular health. Despite significant progress in understanding and managing traditional CVD risk factors, a substantial proportion of CVD cases lack these conventional markers. Recent research has unveiled HPV, a prevalent sexually transmitted infection, as a potential unconventional risk factor for CVD. This review delves into the underlying mechanisms linking HPV to CVD pathogenesis. HPV's influence on vascular endothelium and induction of systemic inflammation are key contributors. Additionally, HPV disrupts host lipid metabolism, further exacerbating the development of atherosclerosis. The link between HPV and CAD is not merely correlative; it encompasses a complex interplay of virological, immunological, and metabolic factors. Understanding the connection between HPV and CVD holds transformative potential. Insights from this review not only underscore the significance of considering HPV as a crucial risk factor but also advocate for targeted HPV screening and vaccination strategies to mitigate CVD risks. This multidisciplinary exploration bridges the gap between infectious diseases and cardiovascular health, emphasizing the need for a comprehensive approach to combating the global burden of cardiovascular disease. Further research and clinical guidelines in this realm are essential to harness the full scope of preventive and therapeutic interventions, ultimately shaping a healthier cardiovascular landscape.

Background: The Global Breast Cancer Initiative (GBCI) Framework, launched by the World Health Organisation (WHO) in 2023, emphasises assessing, strengthening, and scaling up services for the early detection and management of breast cancer. This study aims to determine the feasibility of monitoring the status of breast cancer control in the 21 Asian National Cancer Centers Alliance (ANCCA) countries based on the three GBCI Framework key performance indicators (KPIs): stage at diagnosis, time to diagnosis, and treatment completion. Methods: We reviewed published literature on breast cancer control among 21 ANCCA countries from May to July 2023 to establish data availability and compiled the latest descriptive statistics and sources of the indicators using a standardised data collection form. We performed bivariate Pearson's correlation analysis to measure the strength of correlation between stage at diagnosis, mortality and survival rates, and universal health coverage. Findings: Only 12 (57%) ANCCA member countries published national cancer registry reports on breast cancer age-standardised incidence rate (ASIR) and age-standardised mortality rate (ASMR). Indonesia, Myanmar, and Nepal had provincial data and others relied on WHO's Global Cancer Observatory (GLOBOCAN) estimates. GLOBOCAN data differed from the reported national statistics by 5-10% in Bhutan, Indonesia, Iran, the Republic of Korea, Singapore, and Thailand and >10% in China, India, Malaysia, Mongolia, and Sri Lanka. The proportion of patients diagnosed in stages I and II strongly correlated with the five-year survival rate and with the universal health coverage (UHC) index. Three countries (14%) reported national data with >60% of invasive breast cancer patients diagnosed at stages I and II, and a five-year survival rate of >80%. Over 60% of the ANCCA countries had no published national data on breast cancer staging, the time interval from presentation to diagnosis, and diagnosis to treatment. Five (24%) countries reported data on treatment completion. The definition of delayed diagnosis and treatment completion varied across countries. Interpretation: GBCI's Pillar 1 KPI correlates strongly with five-year survival rate and with the UHC index. Most ANCCA countries lacked national data on cancer staging, timely diagnosis, and treatment completion KPIs. While institutional-level data were available in some countries, they may not represent the nationwide status. Strengthening cancer surveillance is crucial for effective breast cancer control. The GBCI Framework indicators warrant more detailed definitions for standardised data collection. Surrogate indicators which are measurable and manageable in country-specific settings, could be considered for monitoring GBCI indicators. Ensuring UHC and addressing health inequalities are essential to early diagnosis and treatment of breast cancer.

RESUMEN
Significant progress has been achieved in the realm of therapeutic interventions for multiple myeloma (MM), leading to transformative shifts in its clinical management. While conventional modalities such as surgery, radiotherapy, and chemotherapy have improved the clinical outcomes, the overarching challenge of effecting a comprehensive cure for patients afflicted with relapsed and refractory MM (RRMM) endures. Notably, adoptive cellular therapy, especially chimeric antigen receptor T-cell (CAR-T) therapy, has exhibited efficacy in patients with refractory or resistant B-cell malignancies and is now also being tested in patients with MM. Within this context, the B-cell maturation antigen (BCMA) has emerged as a promising candidate for CAR-T-cell antigen targeting in MM. Alternative targets include SLAMF7, CD38, CD19, the signaling lymphocyte activation molecule CS1, NKG2D, and CD138. Numerous clinical studies have demonstrated the clinical efficacy of these CAR-T-cell therapies, although longitudinal follow-up reveals some degree of antigenic escape. The widespread implementation of CAR-T-cell therapy is encumbered by several barriers, including antigenic evasion, uneven intratumoral infiltration in solid cancers, cytokine release syndrome, neurotoxicity, logistical implementation, and financial burden. This article provides an overview of CAR-T-cell therapy in MM and the utilization of BCMA as the target antigen, as well as an overview of other potential target moieties.
RESUMEN
About 95% of cervical cancers worldwide are caused by human papillomavirus (HPV). Cervical cancer is preventable and curable if it is detected and treated early. We reviewed the latest national cervical cancer indicators, and barriers to HPV vaccination and cervical cancer screening in 21 Asian National Cancer Centers Alliance (ANCCA) member countries. Half (n = 11, 52%) of the countries have introduced HPV vaccination for girls as part of their national vaccination programme, three countries reported coverage of over 90%. Most ANCCA member countries have cervical cancer screening programmes, only five countries reported screening uptake of over 50%. The barriers to HPV vaccination coverage and cervical cancer screening participation have been identified. Ensuring health service accessibility and affordability for women, addressing sociocultural barriers, and strengthening the healthcare system and continuum of care are essential to increase HPV vaccination and cervical cancer screening coverage.
RESUMEN
A biomarker is a measurable indicator used to distinguish precisely/objectively either normal biological state/pathological condition/response to a specific therapeutic intervention. The use of novel molecular biomarkers within evidence-based medicine may improve the diagnosis/treatment of disease, improve health outcomes, and reduce the disease's socio-economic impact. Presently cancer biomarkers are the backbone of therapy, with greater efficacy and better survival rates. Cancer biomarkers are extensively used to treat cancer and monitor the disease's progress, drug response, relapses, and drug resistance. The highest percent of all biomarkers explored are in the domain of cancer. Extensive research using various methods/tissues is carried out for identifying biomarkers for early detection, which has been mostly unsuccessful. The quantitative/qualitative detection of various biomarkers in different tissues should ideally be done in accordance with qualification rules laid down by the Early Detection Research Network (EDRN), Program for the Assessment of Clinical Cancer Tests (PACCT), and National Academy of Clinical Biochemistry. Many biomarkers are presently under investigation, but lacunae lie in the biomarker's sensitivity and specificity. An ideal biomarker should be quantifiable, reliable, of considerable high/low expression, correlate with the outcome progression, cost-effective, and consistent across gender and ethnic groups. Further, we also highlight that these biomarkers' application remains questionable in childhood malignancies due to the lack of reference values in the pediatric population. The development of a cancer biomarker stands very challenging due to its complexity and sensitivity/resistance to the therapy. In past decades, the cross-talks between molecular pathways have been targeted to study the nature of cancer. To generate sensitive and specific biomarkers representing the pathogenesis of specific cancer, predicting the treatment responses and outcomes would necessitate inclusion of multiple biomarkers.

Cancer care sector has received significant attention worldwide after an increase in cancer incidence and related mortality every year. There is a large disparity in access to care for cancer patients in view of increasing case number, limited and urban centric cancer care facilities and resource intensive management of cancer along with many other sociodemographic factors. Cancer care delivery is facing many operational challenges at different steps of care globally and it is more pronounced in LMICs. Research directed towards Operations Management (OM) research can provide solutions to many of the challenges encountered during different steps of cancer care and can help us to manage cancer care delivery landscape with cost cutting and quality improvement. The promising abilities of OM is often overlooked for improving various aspects of cancer care despite the fact that its deployment can create OM surplus where the capitals can be tapped to improve the quality of care for the cancer patients. This paper discusses that fundamentals of OM principles must be implemented for creating resilience and gaining effectiveness and efficiency throughout the cancer care operations.

Cancer cachexia is a complex syndrome characterized by progressive weight loss, muscle mass depletion, and systemic inflammation, profoundly affecting the well-being and treatment outcomes of cancer patients. Effective management of cancer cachexia demands a coordinated, multifaceted approach involving various healthcare disciplines and operational strategies. Streamlining care processes is crucial to ensure timely interventions and support, reducing delays in diagnosis and treatment initiation. Multidisciplinary collaboration is pivotal in creating integrated care plans that address the multifactorial nature of cancer cachexia comprehensively. Data-driven decision-making empowers healthcare teams to identify trends, monitor treatment responses, and tailor care plans to individual needs, ultimately leading to improved patient outcomes. Standardized assessment and monitoring play a vital role in maintaining consistent, high-quality care, facilitating early interventions and treatment adjustments. Implementing patient-centered care fosters trust, enhances treatment adherence, and encourages patients to actively engage in their care journey, thereby improving their overall quality of life. This paper underscores the significance of applying operations management principles to optimize care delivery and enhance patient outcomes in the management of cancer cachexia. It provides valuable insights for healthcare institutions and professionals striving to provide comprehensive and effective care for individuals affected by this challenging condition.
RESUMEN
Tobacco kills more than 8 million people worldwide every year. Over 80% of the world's 1.3 billion tobacco users live in low- and middle-income countries (LMICs), where the future burden is projected to grow. At the same time, progress in tobacco control has not advanced as far as in many LMICs. In particular, the implementation of tobacco-cessation programs and interventions remains limited. The bulk of the evidence for tobacco-cessation interventions comes from high-income countries and may not reflect the context in LMICs, particularly as resources and training for tobacco cessation are limited. This paper summarizes the current evidence for tobacco-cessation interventions in LMICs and highlights some key challenges and research gaps. Overall, there is a need to build capacity for locally relevant research and implementation science to support tailored cessation interventions and strategies for LMICs.

India has a rising burden of cancer with an estimated 70% of the cancers caused by modifiable and preventable risk factors. This review was conducted to document the status, analyse the situation and propose the way forward for cancer prevention in India. A desk review of the online databases and reports from the government websites was conducted. The ongoing initiatives including cancer registries, medical and health education and training, and community-based programmes were analysed. This review was done from July 2019 to February 2021. Cancers of the breast, cervix, and lip and oral cavity are the three most common malignancies, with distinct regional variations in India and account for 34% of the 1.15 million cancer cases diagnosed annually. The major initiatives were focused initially on cancer treatment and prevention was added nearly a decade ago. Even with those, the scope and coverage of cancer prevention and treatment services has remained in hospitals and urban settings. India needs to build upon the ongoing approach which seems to be focused on "tracking the cancer, teaching the future and helping the masses" by implementing non-vertical primary healthcare cancer prevention and control approach. Cancer prevention should be made an integral part of the health interventions, rapidly extended to primary healthcare services and facilities, linked with specialised treatment facilities, as India aims for universal health coverage. The opportunity provided by the Ayushman Bharat Programme launched in 2018 should be leveraged for rapid expansion and effective coverage of cancer prevention and treatment interventions in India.
RESUMEN
The intricacies in various signaling routes involved in the menstrual cycle can be impacted by internal as well as external stimuli, and the role of stress, be it physical, psychological, or social, in disturbing the process could be debilitating for a woman. The global endeavor of vaccination rose to protect individuals from the severity of COVID-19, but a conjunction of a short-lived menace of menstrual disturbance in the female population came out as an unsettling side effect. An understanding of the immunological panorama in the female reproductive tract (FRT) becomes important to fathom this issue. The close-knit microenvironment in the FRT shows active microbiota in the lower FRT, but the latest findings are ascertaining the presence of low-biomass microbiota in the upper FRT as well. Concerted signaling, wherein inflammation becomes an underlying phenomenon, results when a stressor elicits molecules of the inflammatory cascade. Learning lessons from the gut microbiota, we need to address the exploration of how FRT microbiota would impose inflammation by manipulating the immune response to vaccines. Since there is a prominent sex bias in the immune response to infectious diseases in women and men, the role of sex hormones and cortisol becomes important. The treatment regimen may be considered differently in women who also consider their ovarian cycle phases. Women exert robust immune response to antigenic encounters via cell-mediated and humoral arms. The inclusion of women in vaccine trials has been marginalized over the years, which resulted in unwanted high dosage administration of vaccines in women.

BACKGROUND: With increasing incidence of cancer worldwide and increasing burden of treatment over the patients with cancer, the caregivers of those patients with cancer also suffer from psychological distress which ultimately affects their Quality of Life (QOL). This aspect is often overlooked which may ultimately lead to compromised patient care. PURPOSE: To translate the Caregiver Quality of Life Index-Cancer (CQOLC) Scale in Hindi and assess its association with Kesslers's psychological distress scale (K-10) for determining the quality of life (QoL) of caregivers of patients with cancer in India. METHODS: This is a single institute, hospital based cross sectional study performed from July 2020 to March 2021. Caregiver Quality of Life Index-Cancer (CQOLC) Scale, employing standard 'forward-backforward' translation procedure, the English-language version of the questionnaire was translated into Hindi-language by experts and administered to each caregiver. Cronbach's alpha was used for internal consistency. Kesslers's psychological distress scale (K-10) was analysed on interview basis. RESULTS: A total evaluated responders were 264. The hindi versions of the CQOLC was validated by cronbach's alpha method with internal consistency between 0.8 and 0.91. The majority of the caregivers were of the age group 31-40 yrs (42.05%). The male to female ratio was 6.54:1. CQOLC good score(0-45) was obtained in 27.27%, fair(46-90) in 55.30% and poor(91-140) in 17.42%. For K-10 distress scale very mild(10-19), mild(20-24), moderate(25-29) and severe(30-50) was observed in 47.73%, 11.74%, 11.74% and 28.79% respectively. A strong relation was found between the caregivers with poor CQOLC score and severe K-10 score(p<0.001). CONCLUSION: The Hindi version of CQOLC was accepted and its correlation with the point psychological distress predictor (K-10) scale was a valuable method to identify caregivers with poor QOL and severe distress levels.

Modern cancer management has changed over the period of time and now shifted to multidisciplinary care approach to ensure a better quality of life (QOL) of the surfing patients. Every form of cancer treatment has side effects and affects the QOL. Many of the side effects have been discussed in detail because of the need for timely interventions to prevent the consequences of the side effects. Dermatological adverse events due to cancer treatment are important but most commonly ignored in our clinical practice. Nursing staffs have a critical role in the early identification of such events and by briefing and training of the nursing staff in the identification of adverse events which can aid in the prevention of complications. As dermatologists may not be available round the clock, nursing staff are looking after the patients round the clock can prove very vital in screening cutaneous AE and adequately setting up referrals to aid early recognition and treatment of not only mild but also potentially life-threatening complications. The nursing staff, which is a cadre of health caregivers that are intimately involved in cancer care, can be trained to identify timely, skin-related adverse events. A literature search of scientific publications was done using the electronic databases PubMed, Science Direct, Cochrane Library, and Google Scholar. The search included terms 'Adverse events (AEs) post-chemotherapy,' 'AE post-radiotherapy,' 'AE post-immunotherapy,' 'AE post-hormonal therapy for cancer' and 'AE post-cancer surgery.' Data obtained from these studies and case reports were compiled and interpreted to prepare this review. This review focuses on various ways in which skin can be involved adversely as a part of cancer management and their classic and tell-tale signs to help the nurses in their better and quicker identification so that dermatologists are timely intimated and the treatment can be instituted to improve the patient's QOL.
