Correlation between work productivity loss and EORTC QLQ-C30 and -BR23 domains from the MONALEESA-7 trial of premenopausal women with HR+/HER2− advanced breast cancer

Cancer research in South Asian Association for Regional Cooperation (SAARC) countries

Cancer is a major global health threat, with 35 million new cases projected by 2050, predominantly in low-income and middle-income-countries. Within South Asian Association for Regional Cooperation (SAARC) countries, a notable gap in cancer research investment and output compared with high-income countries highlights the need to strengthen research capacity. The rising cancer incidence across SAARC countries is not being matched by local research, particularly in clinical trials in molecular biology, targeted therapy, immunotherapy, and cancer vaccines. This paucity of research is problematic as guidelines and therapies developed in high-income countries might not be directly applicable to low-income and middle-income countries due to distinct regional sociocultural, genetic, and environmental factors and are often impractical in these countries due to cost and implementation challenges. This Series paper examines the cancer research landscape within SAARC countries, focusing on Bangladesh, Nepal, Sri Lanka, India, Pakistan, Afghanistan, Bhutan, and Maldives. We analyse PubMed publication rates and examine available infrastructure, current research (including clinical trials), and limitations and disparities among SAARC countries in terms of cancer research. Key challenges include disparities in health-care access, cultural and economic barriers, and little funding and infrastructure. Strengthening cancer research in SAARC countries requires building collaborative networks, improving research facilities and training, focusing on local epidemiological studies, and developing affordable technologies and treatments. Effective policy and stakeholder engagement could greatly advance cancer care in the region.

Breast cancer-related mortality in Central and Eastern Europe: years of life lost and productivity costs

BACKGROUND

Breast cancer (BC) poses a public health challenge as the most commonly diagnosed cancer among women globally. While BC mortality has declined across Europe in the past three decades, an opposite trend has been reported in some transitional European countries. This analysis estimates the mortality burden and the cost of lost productivity due to BC deaths in nine Central and Eastern Europe (CEE) countries: Bulgaria, Croatia, Czech Republic, Hungary, Poland, Romania, Serbia, Slovakia, and Slovenia, that have defied the favorable cancer mortality trends. These estimates may provide relevant evidence to aid decision-makers in the prioritization of BC-targeted policies.

METHODS

The human capital approach (HCA) was used to estimate years of life lost (YLL) and productivity losses due to premature death from BC (ICD-10 code: C50 Malignant neoplasm of breast). YLL and present value of future lost productivity (PVFLP) were calculated using age and gender-specific mortality, wages, and employment rates. Data were sourced from the World Health Organization (WHO), Eurostat, and the World Bank.

RESULTS

In 2019, there were 19,726 BC deaths in the nine CEE countries. This study estimated BC deaths resulted in 267,184 YLL. Annual PVFLP was estimated to be €85 M in Poland, €46 M in Romania, €39 M in Hungary, €21 M in Slovakia, €18 M in Serbia, €16 M in Czech Republic, €15 M in Bulgaria, €13 M in Croatia, and €7 M in Slovenia.

CONCLUSION

Premature death from BC leads to substantial YLL and productivity losses. Lost productivity costs due to premature BC-related mortality exceeded €259 million in 2019 alone. The data modeled provide important evidence toward resource allocation priorities for BC prevention, screening, and treatment that could potentially decrease productivity losses. Careful consideration should be given to BC-specific policies, such as surveillance programs and the availability of new treatments in CEE countries to decrease the medical and financial burden of the disease.

The predictive value of patient-reported outcomes on the impact of breast cancer treatment-related quality of life

Purpose

Patient-reported outcomes (PROs) have been widely used to measure breast cancer (BC) treatment outcomes. However, evidence is still limited on using routinely PROs to personalize treatment decision-making, including or not chemotherapy, targeted therapy, and radiotherapy. Using patient baseline PRO scores, we aimed to use PROs before treatment initiation to predict improvement or decline in health-related quality of life (HRQoL) due to treatment that they receive.

Methods

In two French cancer sites, women with non-metastatic BC completed the EORTC QLQ-C30 and QLQ-BR23 and BREAST-Q questionnaires to assess their PROs at baseline and again at 6 months. The outcome measured was post-operative change in PROs with minimal important difference for QLQ-C30 domains. We performed multivariate ordinal logistic regression to estimate the incremental probability of post-operative PRO improvements and deteriorations depending upon treatment options and baseline HRQoL.

Results

One hundred twenty-seven women completed questionnaires. Chemotherapy had significant negative impacts on Global health status (GHS) and on physical and social functioning. Chemotherapy and radiotherapy increased patient fatigue scores after adjusting for clinical factors (p< 0.01 and p< 0.05, respectively). The incremental probability of GHS deteriorations for chemotherapy was +0.3, +0.5, and +0.34 for patients with baseline GHS scores of 40, 70, and 100, respectively. This showed that different pre-treatment PROs might predict differential effects of chemotherapy on women change in HRQoL.

Conclusion

Patients with different baseline PRO scores may experience dissimilar impacts from BC treatments on post-operative PROs in terms of improvements and deteriorations. Oncologists might decide to adapt the treatment option based on a given level of the negative impact. Future studies should concentrate on incorporating this information into routine clinical decision-making strategies to optimize the treatment benefit for patients.

Work productivity among patients with metastatic breast cancer in the United States

OBJECTIVE

To characterize workplace productivity measures in patients with metastatic breast cancer (mBC) using line of therapy (LOT) and first line (1 L) regimen.

METHODS

A retrospective cohort study was conducted using IBM's MarketScan Commercial Claims and Encounters (CCAE) and Health and Productivity Management (HPM) databases. The cohort included patients diagnosed with mBC who initiated 1 L treatment between 2/3/2015 and 6/30/2018. Productivity was measured using days absent from work and short- and long-term disability (STD, LTD) claims by LOT and 1 L regimen (any cyclin-dependent kinase 4/6 inhibitor [CDK4/6i], endocrine monotherapy, chemotherapy only, or other anti-cancer therapy [OACT]). LOT was defined using regimen-based progression.

RESULTS

Overall, 548 patients were included; 148, 129, 145, and 126 received endocrine monotherapy, CDK4/6i, chemotherapy only, and OACT, respectively. The rate of LTD increased significantly by 3.1 and 2.6 times from 1 L to second line (2 L) and from 2 L to subsequent lines, respectively. Patients receiving 1 L chemotherapy had 2.4- and 2.7-times odds of using STD and LTD compared to patients receiving 1 L CDK4/6i.

CONCLUSIONS

Regimen-based disease progression is associated with increased use of STD and LTD. Patients with a 1 L regimen of chemotherapy have significantly higher odds of using STD or LTD than patients using 1 L CDK4/6i.
