Comprehensive Geriatric Assessment for Older Women with Early-Stage (Non-Metastatic) Breast Cancer-An Updated Systematic Review of the Literature

BACKGROUND

A previous systematic review by our team (2012) undertook comprehensive geriatric assessment (CGA) in breast cancer and concluded there was not sufficient evidence to instate CGA as mandatory practice. SIOG/EUSOMA guidelines published in 2021 advocate the use of CGA in breast cancer patients. The aim is to perform an updated systematic review of the literature.

METHODS

A systematic review of studies published between 2012 and 2022 that assessed the use of CGA in breast cancer was performed on Cochrane, PubMed and Embase.

RESULTS

A total of 18 articles including 4734 patients with breast cancer were identified. The studies covered four themes for use of CGA in breast cancer: (1) to determine factors influencing survival (2) as an adjunct to treatment decision-making (3) to measure quality of life, and (4) to determine which tools should be included. There was evidence to support the use of CGA in themes 1-3; however, it is uncertain which assessment tools are best to use (theme 4).

CONCLUSIONS

CGA can be used to determine factors affecting survival and quality of life in breast cancer patients and can therefore be used to aid treatment decision-making. Further work is required to determine gold standard CGA.

The role of comorbidity assessment in guiding treatment decision-making for women with early breast cancer: a systematic literature review

PURPOSE

Comorbidity in breast cancer patients impacts treatment choice, toxicity, and outcomes. While comorbidity measurement tools are frequently used by researchers, little is known about their use in clinical practice. The aim of this review was to examine the use of comorbidity measurement tools in clinical practice and their role in treatment decision-making in breast cancer.

METHODS

Six electronic databases were searched from inception to 21 March 2019. Quantitative or mixed methods studies addressing primary treatment of breast cancer and identifying a comorbidity measurement tool used in clinical practice treatment decision-making were included. Data was extracted on tool utilized, impact on treatment decisions or outcomes, pattern of use, and psychometric properties.

RESULTS

A systematic search of literature yielded 752 studies. Of the four studies that met inclusion criteria, each utilized a comprehensive geriatric assessment tool, though only in a subset of patients. No studies found direct comorbidity measurement tools utilized independently of geriatric assessment. Assessment results had variable impact on treatment decisions. Impacts on patient mortality and treatment toxicity, cost-effectiveness, and psychometric characteristics of the tools were not identified.

CONCLUSIONS

There is little evidence on use of specific comorbidity tools in clinical decision-making in breast cancer outside of comorbidity assessment as part of geriatric assessment tools. There was limited impact on decision-making or patient outcomes when these were utilized. Further research is needed to identify barriers to comorbidity assessment in clinical practice and identify comorbidity tools that have the potential to improve patient outcomes.
