Solitary Living Worsens the Continuation of Adjuvant Chemotherapy for Gastric Cancer
European journal of surgical oncology(2023)
摘要
Background: No studies have reported the effect of solitary living on adjuvant chemotherapy continu-ation in patients with gastric cancer. This study aimed to investigate the influence of solitary living on the efficacy of adjuvant chemotherapy after curative gastrectomy.Methods: We enrolled 155 patients with pathological stage II/III gastric cancer who underwent gas-trectomy and adjuvant chemotherapy between January 2013 and March 2020. The patients were divided into two groups according to their living conditions, the solitary group (n = 34) versus the non-solitary group (n = 121). Clinicopathological features, predictive factors for the continuation of adjuvant chemotherapy, and long-term survival were compared between the two groups.Results: The median body weight loss (BWL) at one month after surgery (8.9% vs. 7.0%, p = 0.01), and the rates of failure to continue six courses of chemotherapy were higher in the solitary group (41.2% vs. 14.9%, p = 0.002) than in the non-solitary group. Multivariate analysis revealed that solitary living was an independent predictive factor for discontinuing adjuvant chemotherapy (odds ratio 3.36, 95% confidence interval [CI; 1.32-8.58], p = 0.01) as well as 10% BWL at one month after surgery (odds ratio 3.99, 95% CI [1.57-10.2], p = 0.004). The relapse-free survival was significantly worse in the solitary group (p = 0.03).Conclusions: Solitary living may be an independent risk factor for discontinuation of adjuvant chemo-therapy in patients with gastric cancer. It is necessary to examine whether social and medical support organized by medical institutes and the government improves the continuation of adjuvant chemo-therapy in patients living alone.(c) 2022 Elsevier Ltd, BASO -The Association for Cancer Surgery, and the European Society of Surgical Oncology.
