Purpose
In very elderly cancer patients, health-related quality of life (HRQOL) is a particularly important issue but has rarely been studied due to a lack of specific instruments and of reference data. We performed a prospective analysis of HRQOL in patients ≥80 years undergoing radiotherapy with the newly validated elderly-specific HRQOL module EORTC QLQ-ELD14.
Methods
We prospectively assessed HRQOL in n = 50 radiotherapy patients ≥80 years (32 % lung, 20 % gastrointestinal, 8 % each of breast, head and neck, gynecologic cancer) at the start (t1), end (t2), and 6 months after (t3) radiotherapy, using EORTC QLQ-C30 and EORTC QLQ-ELD14. Overall survival was determined in the whole cohort and subgroups.
Results
Median overall survival from the start of radiotherapy was 15 months; 1-year and 2-year overall survival rates were 57.1 and 31.0 %, respectively. Eastern Cooperative Oncology Group (ECOG) performance status <2, Charlson comorbidity index ≤6, curative treatment intention, local tumor stage Union Internationale Contre le Cancer (UICC I, II), and total dose >45 Gy were associated with prolonged survival. No significant changes in any HRQOL domain were observed during the course of treatment (t1 to t2). Six months after radiotherapy (t3), a significant and clinically relevant deterioration of HRQOL was seen in EORTC QLQ-C30 for physical function and role function and in EORTC QLQ-ELD14 for future worries, burden of illness, and family support.
Conclusions
In radiotherapy patients ≥80 years, HRQOL was maintained until the end of radiotherapy but deteriorated in general and elderly-specific areas thereafter, suggesting a need to develop specific supportive interventions for this age group.
