Estimating child mortality associated with maternal mortality from breast and cervical cancer.

BACKGROUND: Large-scale population studies demonstrate an association between mothers' deaths and child mortality in both lower and higher income countries. The authors estimated children's deaths in association with mothers' deaths from breast or cervical cancer, 2 common cancers in low-income and middle-income countries affecting women of reproductive age, to develop a comprehensive assessment of the death burden of these cancers. METHODS: A Monte Carlo simulation model was devised whereby women were at risk of dying from breast cancer, cervical cancer, or another cause. Compared with children who have living mothers, children of women who die before they reached age 10 years have an elevated risk of death from all causes. Therefore, simulations were conducted, and the impact of mothers' deaths from cervical and breast cancer on associated child mortality was quantified for Bangladesh, Burkina Faso, and Denmark (benchmark analysis), then the analyses were extended to all African countries. RESULTS: Benchmark estimates of child deaths associated with mothers' deaths from breast and cervical cancer resulted in an increment in cancer-related mortality of approximately 2% in Bangladesh, 14% in Burkina Faso, and less than 1% in Denmark. The model predicted an increment in comprehensive cancer deaths when including child death estimates by as high as 30% in certain African countries. CONCLUSIONS: To the authors' knowledge, this is the first study to estimate the impact of a mother's death from cancer on child mortality. The model's estimates call for further investigation into this correlation and underscore the relevance of adequate access to prevention and treatment among women of childbearing age.

Novel Pilot Curriculum for International Education of Lymphoma Management Using E-Contouring.

PURPOSE: The International Lymphoma Radiation Oncology Group (ILROG) published consensus guidelines on the management of Hodgkin disease (HD) and nodal non-Hodgkin lymphoma (NHL), which became the most downloaded articles from International Journal of Radiation Oncology, Biology, and Physics. E-contouring workshops allow for interactive didactic sessions, allowing participants to see case-based contouring in real time. A pilot 1-hour curriculum was developed with the objective of reviewing ILROG guidelines for HD and NHL management with incorporation of e-contouring tools. This represents the first international education intervention in Spanish using e-contouring with a pre- and postintervention questionnaire. METHODS: A 1-hour presentation was prepared in Spanish reviewing the ILROG recommendations for HD and NHL. The review was followed by the author's demonstration of contour creation using patients with HD and NHL prepared for the American Society for Radiation Oncology's 2015 e-contouring lymphoma session. A five- question evaluation was prepared and administered before and after intervention. A two-tailed paired t test was performed to evaluate any significant change in test value before and after intervention. RESULTS: A total of nine quizzes were collected before and after the intervention. The average test score before the intervention was 75.6%, and the average test score after the intervention was 86.7% ( P = .051). Four students scored 100% on both the pre- and postintervention evaluations, and no student had a decrease in score from pre- to postintervention evaluation. The topic with the lowest score tested dose consideration. CONCLUSION: A substantial but nonsignificant improvement in test evaluation was seen with this pilot curriculum. This pilot intervention identified obstacles for truly interactive didactic sessions that, when addressed, can lead to fully developed interactive didactic sessions.

Cost in perspective: direct assessment of American market acceptability of Co-60 in gynecologic high-dose-rate brachytherapy and contrast with experience abroad.

PURPOSE: While Ir-192 remains the mainstay isotope for gynecologic high-dose-rate (HDR) brachytherapy in the U.S., Co-60 is used abroad. Co-60 has a longer half-life than Ir-192, which may lead to long-term cost savings; however, its higher energy requires greater shielding. This study analyzes Co-60 acceptability based on a one-time expense of additional shielding and reports the financial experience of Co-60 in Peru's National Cancer Institute, which uses both isotopes. MATERIAL AND METHODS: A nationwide survey was undertaken assessing physician knowledge of Co-60 and willingness-to-pay (WTP) for additional shielding, assuming a source more cost-effective than Ir-192 was available. With 440 respondents, 280 clinicians were decision-makers and provided WTPs, with results previously reported. After completing a shielding report, we estimated costs for shielding expansion, noting acceptability to decision makers' WTP. Using activity-based costing, we note the Peruvian fiscal experience. RESULTS: Shielding estimates ranged from $173,000 to $418,000. The percentage of respondents accepting high-density modular or lead shielding (for union and non-union settings) were 17.5%, 11.4%, 3.9%, and 3.2%, respectively. Shielding acceptance was associated with greater number of radiation oncologists in a respondent's department but not time in practice or the American Brachytherapy Society membership. Peru's experience noted cost savings with Co-60 of $52,400 annually. CONCLUSIONS: By comparing the cost of additional shielding for a sample institution's HDR suite with radiation oncologists' WTP, this multi-institutional collaboration noted < 20% of clinicians would accept additional shielding. Despite low acceptability in the US, Co-60 demonstrates cost-favorability in Peru and may similarly in other locations.
