Quality of care in Colombian women with early-onset breast cancer in two time periods: findings from a nationwide administrative registry cohort

Background

Early-onset breast cancer (EOBC) refers to breast cancer diagnosed in women aged 18-45 years, being in many cases associated with hereditary breast cancer syndromes, diagnosed at more advanced stages and worse prognosis. In this paper, we sought to describe the main characteristics of EOBC and quality of care within the framework of the national health system in Colombia.

Methods

Cross-sectional study. We used a national administrative cancer registry, including women diagnosed with EOBC between 2017 and 2022. Demographic and clinical characteristics, as well as quality healthcare indicators, were compared (numbers and percentages) over two periods (2017-2019, 2020-2022), stratified by health insurance scheme.

Findings

7621 women with incident EOBC were included, constituting 19.4% (7621/39,238) of all breast cancers reported in the study period. The mean age was 39.2 (SD 5.2). Most of the cases (23% [1753/7621]) were diagnosed at stage IIA. Systemic therapy was the most frequent first treatment. When comparing both periods, the main areas of improvement were related to breast-conserving surgery for early stages (from 60.3% [459/761] to 68.3% [699/1024]), access to palliative care for metastatic cancer (from 29.5% [59/199] to 54.9% [101/184]), and reduction of waiting times. The time from collecting biopsy samples to receiving results showed the biggest improvement between periods (from a mean of 24.5 to 5.0 days). However, delays in initiating treatment persist, with an average of over two months.

Interpretation

While the quality of breast cancer care in women with EOBC has improved in recent years in Colombia, mainly due to better access to specific technologies and treatments, there are important challenges regarding early detection and health services delays that require corrective measures.

Targeting Education as a Barrier to Implement Hypofractionation: Results of a Country-Wide Training Program

Introduction

Access to radiation therapy in low- and middle-income countries (LMICs) could be improved with modern hypofractionated radiation therapy schedules, although their adoption remains limited. We aimed to evaluate perceptions regarding hypofractionation and the effect of a dedicated curriculum in an LMIC.

Methods and Materials

We developed a pilot e-learning hypofractionation curriculum focused on breast, prostate, rectal cancer, and high-grade glioma in Colombia. International educators taught 13 weekly, 90-minute sessions. Participants completed pre- and postcurriculum questionnaires regarding hypofractionation attitudes, 1 to 5 Likert-scale self-confidence, and practices for 12 clinical scenarios. Physicians' responses were categorically scored "1" (for hypofractionation or ultrahypofractionation) or "0" (for conventional fractionation). We used the paired t test to measure pre- versus postcurriculum differences in self-confidence and the McNemar test to detect differences in hypofractionation selection.

Results

Across 19 cities in Colombia, 147 clinicians enrolled: 61 radiation oncologists, 6 radiation oncology residents, 59 medical physicists, 18 physics residents, and 3 other staff. Among physicians, education was the greatest barrier to select hypofractionation, common in ultrahypofractionation for prostate (77.6%) and breast cancer (74.6%) and less common for moderate hypofractionation of prostate (61.2%) and breast cancer (52.2%). Additional perceived barriers included unfamiliarity with clinic protocols (7%-22%), clinical experience (5%-15%), personal preference (3%-16%), and lack of technology (3%-20%), with variation across different clinical settings. After the curriculum, paired (n = 38) physicians' selection of hypofractionation increased across all disease sites (mean aggregate score 6.2/12 vs 8.2/12, P <.001). Self-confidence among paired clinicians (n = 87) increased for prostate ultrahypofractionation (+0.45), rectal ultrahypofractionation (+0.43), breast hypofractionation (+0.38), and prostate hypofractionation (+0.23) (P ≤ .03).

Conclusions

In an LMIC with a bundled payment system, lack of education and training was a perceived barrier for implementation of hypofractionation and ultrahypofractionation. A targeted e-learning hypofractionation curriculum increased participant confidence and selection of hypofractionated schedules.

Fighting Cancer around the World: A Framework for Action

Tackling cancer is a major challenge right on the global level. Europe is only the tip of an iceberg of cancer around the world. Prosperous developed countries share the same problems besetting Europe-and the countries and regions with fewer resources and less propitious conditions are in many cases struggling often heroically against a growing tide of disease. This paper offers a view on these geographically wider, but essentially similar, challenges, and on the prospects for and barriers to better results in this ceaseless battle. A series of panels have been organized by the European Alliance for Personalised Medicine (EAPM) to identify different aspects of cancer care around the globe. There is significant diversity in key issues such as NGS, RWE, molecular diagnostics, and reimbursement in different regions. In all, it leads to disparities in access and diagnostics, patients' engagement, and efforts for a better understanding of cancer.

Estimation of the Need for Radiation Therapy Services According to the Incidence of Cancer in Colombia to 2035

Purpose

To estimate the supply and demand of current and future radiation therapy services by 2035 for Colombia.

Methods and Materials

The present study was performed by surveying different radiation therapy services identified in Colombia through the Colombian Association of Radiation Oncology. The demand was estimated based on incident cases and published information on the use of radiation therapy by type of cancer. Future demand was estimated under the assumption that incidence rates do not change and therefore the change in the number of cases is due to the change in the age structure of the Colombian population. Sensitivity analyses were conducted on the percentage of radiation therapy use by type of cancer. A Monte Carlo simulation was carried out to estimate the distribution of cases requiring radiation therapy, the amount of equipment, and the number of staff needed for care with the use of this technology.

Results

In total, Colombia has 69 linear accelerators, 2 radiosurgery equipment, 30 high-dose-rate brachytherapy pieces of equipment, 124 radiation therapy oncologists (113 working, 9 not working, and 2 not informed), and 275 radiation therapy technologists as of June 2020. It was estimated that to meet the current cancer burden the country would need a total of 162 radiation therapy oncologists, 121 medical physicists, and 323 radiation therapy technologists and to increase the number of radiation therapy technologists, radiation therapy oncologists, and medical physicists to 491, 246, and 184, respectively, to meet the disease burden by 2035 (73,684-88,743 cases per year).

Conclusions

In Colombia it is estimated that there is a deficit of human resources and technology for radiation therapy; therefore, there is need to investment resources from the public and private sectors to provide timely and quality care to cancer patients requiring this treatment.
