RESUMO

PURPOSE: Genomic cancer risk assessment (GCRA) is standard-of-care practice that uses genomic tools to identify individuals with increased cancer risk, enabling screening for early detection and cancer prevention interventions. GCRA is not available in most of Mexico, where breast cancer (BC) is the leading cause of cancer death and ovarian cancer has a high mortality rate. METHODS: Guided by an implementation science framework, we piloted the Genomic Risk Assessment for Cancer Implementation and Sustainment (GRACIAS) intervention, combining GCRA training, practice support, and low-cost BRCA1/2 (BRCA) gene testing at four centers in Mexico. The RE-AIM model was adapted to evaluate GRACIAS intervention outcomes, including reach, the proportion of new patients meeting adapted National Comprehensive Cancer Network criteria who participated in GCRA. Barriers to GCRA were identified through roundtable sessions and semistructured interviews. RESULTS: Eleven clinicians were trained across four sites. Mean pre-post knowledge score increased from 60% to 67.2% (range 53%-86%). GCRA self-efficacy scores increased by 31% (95% CI, 6.47 to 55.54; P = .02). Participant feedback recommended Spanish content to improve learning. GRACIAS promoted reach at all sites: 77% in Universidad de Guadalajara, 86% in Instituto Nacional de Cancerología, 90% in Tecnológico de Monterrey, and 77% in Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán. Overall, a pathogenic BRCA variant was identified in 15.6% (195 of 1,253) of patients. All trainees continue to provide GCRA and address barriers to care. CONCLUSION: We describe the first project to use implementation science methods to develop and deliver an innovative multicomponent implementation intervention, combining low-cost BRCA testing, comprehensive GCRA training, and practice support in Mexico. Scale-up of the GRACIAS intervention will promote risk-appropriate care, cancer prevention, and reduction in related mortality.

RESUMO

BACKGROUND: Treatment options are limited for patients with advanced hepatocellular carcinoma (HCC) that progresses after treatment with sorafenib. Cabozantinib, an oral small molecule inhibitor of multiple tyrosine kinase receptors, recently showed improved overall survival (OS) compared with placebo in sorafenib-pretreated patients with advanced HCC in the CELESTIAL trial. This study assessed the cost-effectiveness of cabozantinib for second-line treatment of patients with advanced HCC from a US healthcare system perspective. PATIENTS AND METHODS: Cost and utility data were extracted from the CELESTIAL trial and used to determine the cost-effectiveness of cabozantinib compared with placebo plus best supportive care. The main outcome of this study was the incremental cost-effectiveness ratio (ICER), expressed as cost per quality-adjusted life year (QALY) gained by using cabozantinib compared with placebo plus best supportive care in sorafenib-pretreated HCC. RESULTS: In the base-case analysis using data from the CELESTIAL trial, the incremental QALY and ICER were 0.067 and $1,040,675 for cabozantinib compared with placebo and best supportive care. OS reported in the CELESTIAL trial (hazard ratio, 0.76; 95% CI, 0.63-0.92) had the strongest association with the ICER. In one-way sensitivity analyses, there were no scenarios in which cabozantinib was cost-effective. In a cost-threshold analysis, cabozantinib would have to be priced at least $50 per pill to be cost-effective considering a willingness to pay of $100,000 per QALY. Although the CELESTIAL trial demonstrated that cabozantinib improves OS compared with placebo in patients with HCC that progresses after treatment with sorafenib, our analysis shows that cabozantinib is not a cost-effective therapy in this scenario. CONCLUSIONS: At current costs, cabozantinib is not cost-effective for second-line therapy of HCC in the United States.

RESUMO

The aging of the population is a global challenge. The number of older adults is rapidly growing, leading to an increase in the prevalence of noncommunicable diseases associated with aging, such as cancer. Worldwide, older adults account for approximately half of all cancer cases, and this proportion is projected to increase globally. Furthermore, the majority of older adults live in less developed regions, where health systems are generally ill-equipped to provide care for complex chronic conditions. Worldwide, there is paucity of geriatric training, and most of the oncology workforce lacks the skills and knowledge to provide comprehensive care for older patients. Various initiatives aimed at providing adequate clinical care for older adults, increasing the geriatric skills and knowledge of healthcare professionals, and developing geriatric oncology research, have been successfully implemented. However, most developments in geriatric oncology have taken place in high-income countries, and there are still large inequalities in the availability of clinical, educational, and research initiatives across different regions of the world. This article provides an overview of geriatric oncology initiatives in Asia, Europe, Australia and New Zealand, Latin America, and the United States and Canada. Understanding the achievements and challenges of geriatric oncology around the world, and fostering international collaboration in research and training are essential for improving the care of all older adults with cancer.

RESUMO

Cancer is one of the major non-communicable diseases posing a threat to world health. Unfortunately, improvements in socioeconomic conditions are usually associated with increased cancer incidence. In this Commission, we focus on China, India, and Russia, which share rapidly rising cancer incidence and have cancer mortality rates that are nearly twice as high as in the UK or the USA, vast geographies, growing economies, ageing populations, increasingly westernised lifestyles, relatively disenfranchised subpopulations, serious contamination of the environment, and uncontrolled cancer-causing communicable infections. We describe the overall state of health and cancer control in each country and additional specific issues for consideration: for China, access to care, contamination of the environment, and cancer fatalism and traditional medicine; for India, affordability of care, provision of adequate health personnel, and sociocultural barriers to cancer control; and for Russia, monitoring of the burden of cancer, societal attitudes towards cancer prevention, effects of inequitable treatment and access to medicine, and a need for improved international engagement.

RESUMO

Breast cancer is a major public health issue in low-income and middle-income countries. In Mexico, incidence and mortality of breast cancer have risen in the past few decades. Changes in health-care policies in Mexico have incorporated programmes for access to early diagnosis and treatment of this disease. This Review outlines the status of breast cancer in Mexico, regarding demographics, access to care, and strategies to improve clinical outcomes. We identify factors that contribute to the existing disease burden, such as low mammography coverage, poor quality control, limited access to diagnosis and treatment, and insufficient physical and human resources for clinical care.
