Health related quality of life among postmenopausal woman with hormone responsive HER2- breast cancer in Indonesia

OBJECTIVES

Breast cancer (BC) in women could decrease health-related quality of life (HRQoL). HRQoL becomes important to be assessed to design a relevant treatment that could improve patient outcomes. Furthermore, assessing HRQoL by measuring health state utilities becomes pivotal for health economic evaluation. This study aimed to describe the HRQoL of postmenopausal women with hormone responsive (HR+) HER2- BC using the EQ5D5L instrument in Indonesia.

METHODS

A cross-sectional study was conducted among 126 patients in Dr. Sardjito Hospital in Indonesia. The HRQoL was assessed by interviewing BC patients using the EQ5D5L questionnaire, and the utility index was calculated using the Indonesian value set. Information regarding clinical characteristic and socio-demographic were gained from patient medical records. One-way ANOVA and post-hoc Scheffe's test was performed to compare the utility score within the health state.

RESULTS

Of the 126 patients, a mean ± SD for the age of 59.2 ± 6.1 years. The major problems of patients were pain/discomfort (75.4%) followed by anxiety/depression (54.8%). The mean (SD) of EQ5D VAS was 76.64 (14.91). Mean (SD) of utility score was 0.87 (0.10), 0.77 (0.19) and 0.58 (0.44) for free metastasis (FM), locoregional metastasis (LM) and distant metastasis (DM), respectively. Poor QoL was observed at DM health state (p<0.05).

CONCLUSIONS

HRQoL of postmenopausal women with HR+ HER2- BC was low. The major reported problems were pain/discomfort and anxiety/depression.
