Abstract
- PURPOSE Research studies have demonstrated that comprehensive geriatric assessment (CGA) improves outcomes in older adults with cancer treated with chemotherapy. We compared survival outcomes on older adults with advanced cancer before and after the initiation of a geriatric oncology service (GOS) in a single Japanese cancer center. METHODS This was a comparative study of two groups of consecutive patients 70 years and older with advanced cancer who were referred to medical oncology for first-line chemotherapy before (controls; n = 151, September 2015-August 2018) and after (GOS; n = 191, September 2018-March 2021) implementation of the GOS. When the treating physician requested a consultation from the GOS, a geriatrician and an oncologist performed CGA and provided recommendations for cancer treatment and geriatric interventions. Time to treatment failure (TTF) and overall survival (OS) were compared between the two groups. RESULTS The median age for all patients was 75 (range, 70-95) years, and 85% had GI cancers. In the GOS group, 82 patients received the CGA before a treatment decision and oncologic treatment plans were changed in 49 patients (60%). The overall implementation rate of the CGA-based geriatric interventions was 45%. Two hundred and eighty-two patients received chemotherapy (controls; n = 128 and GOS; n = 154), and 60 patients were treated with best supportive care only (controls; n = 23 and GOS; n = 37). Among patients receiving chemotherapy, TTF event rates for the GOS group compared with the control group were 5.7% versus 14% at 30 days (P = .02) and 13% versus 29% at 60 days (P = .001). The GOS group had longer OS than the control group with a hazard ratio of 0.64 (95% CI, 0.44 to 0.93; P = .02). CONCLUSION In this study, older adults with advanced cancer managed after the implementation of a GOS had improved survival outcomes compared with a historical control of patients.
