Is chemotherapy in elderly patients with metastatic or recurrent gastric cancer as tolerable and effective as in younger patients?

초록

Aim: To analyze the chemotherapy regimens and outcomes of advanced gastric cancer (AGC) patients older than 70 years of age. Methods: Between May 2001 and October 2009, 1135 patients with metastatic or recurrent gastric cancer received palliative chemotherapy. Of these patients 56 (4.9%) were =70 years old and were analyzed retrospectively. Results: The median age at the time of first-line chemotherapy was 73 years (range, 7085) and the median Charlson comorbidity index was 0 (05). In all 17 patients (30%) received surgery with curative or palliative intent; 43 (77%) were treated by doublet or triplet first-line chemotherapy regimens and 13 patients (23%) received single agent chemotherapy. Median progression-free survival for first-line chemotherapy was 3.97 months (95% CI 2.055.89) with an overall response rate of 26%. After the first-line chemotherapy, only 18 of 56 (32%) patients received second-line chemotherapy. The median overall survival (OS) was 12.4 months (95% CI 2.8121.99). In multivariate analysis, receiving surgery and disease control for first-line chemotherapy were independent prognostic factors for increased OS for all 56 patients. Conclusion: Patients older =70 years with metastatic or recurrent gastric cancer might achieve clinical benefit from chemotherapy. Receiving surgery and response of over more stable disease for first-line chemotherapy were independent prognostic factors for increased OS.
