PURPOSE: Patients with unresectable advanced metastatic gastric cancer have a poor prognosis. This study examined the incidence and prognostic impact of cachexia during systemic drug treatment in such patients.
METHODS: We enrolled patients with unresectable advanced gastric cancer who were treated with chemotherapy at Kochi Medical School from 2007 to 2020. Cancer cachexia was defined as > 5% weight loss or > 2% weight loss with a body mass index of < 20 kg/m2 within the past 6 months. Associations between clinicopathological parameters, cancer cachexia, and the overall survival were analyzed.
RESULTS: Cancer cachexia occurred in 55.2% of 134 enrolled patients 6 months after chemotherapy. The incidence of cancer cachexia in initial unresectable gastric cancer was significantly higher than that in patients with recurrent cancer after curative resection. The median overall survival was significantly lower in the patients with cancer cachexia than in those without cancer cachexia at 6 months after starting systemic chemotherapy (13.7 months vs. 21.6 months, P = 0.032). Cancer cachexia at 6 months of starting treatment and CRP > 0.14 were identified as significantly associated with poor outcomes in a multivariate analysis (hazard ratio [HR] 1.339, 95% confidence interval [CI] 1.160-2.085, P = 0.019; HR 1.885, 95% CI 1.124-3.161, P = 0.016); respectively).
CONCLUSIONS: Cancer cachexia was frequently observed in unresectable advanced gastric cancer patients who received chemotherapy and was useful as a prognostic factor for the overall survival.
