[Abstract]
Objective: Intraperitoneal (IP) chemotherapy through subcutaneous port is an effective treatment for gastric cancer (GC) patients with peritoneal metastasis (PM). The objective of this study is to assess the port complications and risk factors for complications in GC patients with PM.
Methods: In retrospective screening of 301 patients with subcutaneous ports implantation, 249 GC patients with PM who received IP chemotherapy were screened out for analysis. Port complications and risk factors for complications were analyzed.
Results: Of the 249 analyzed patients, 57 (22.9%) experienced port complications. Subcutaneous liquid accumulation (42.1%) and infection (28.1%) were the main complications, and other complications included port rotation (14.1%), wound dehiscence (12.3%), inflow obstruction (1.7%) and subcutaneous metastasis (1.7%). The median interval between port implantation and occurrence of complications was 3.0 months. Eastern Cooperative Oncology Group (ECOG) performance status [odds ratio (OR), 1.74; 95% confidence interval (95% CI), 1.12−2.69], albumin (OR, 3.67; 95% CI, 1.96−6.86), implantation procedure optimization (OR, 0.33; 95% CI, 0.18−0.61) and implantation groups (OR, 0.37; 95% CI, 0.20−0.69) were independent risk factors for port complications (P<0.05). ECOG performance status was the only factor that related to the grades of port complications (P=0.016).
Conclusions: Port complications in GC patients who received IP chemotherapy are manageable. ECOG performance status, albumin, implantation procedure and implantation group are independent risk factors for port complications in GC patients with PM.
【中文摘要】
目的: 腹腔化療可將藥物直接作用於腹腔腹膜轉移病灶,已被應用於胃癌腹膜轉移的治療。通過皮下放置腹腔化療港可反覆多次進行腹腔化療。而腹腔化療港的正確放置及安全應用是實施腹腔化療的前提,本研究目的是分析腹腔化療港相關併發症及發生的相關危險因素。
方法: 回顧性分析上海交通大學醫學院瑞金醫院301例皮下放置腹腔化療港患者的臨床資料,經過篩選其中249胃癌腹膜轉移患者符合分析條件,進一步分析腹腔化療港在胃癌腹膜轉移患者腹腔化療過程中的併發症、危險因素及處理措施。
結果: 分析的249例胃癌腹膜轉移患者中有57 (22.9%) 例患者發生了化療港相關的併發症。其中,皮下積液 (42.1%) 和感染 (28.1%) 是主要的併發症,其他相關的併發症還包括旋轉 (14.1%), 切口裂開 (12.3%), 堵塞 (1.7%) 和皮下轉移 (1.7%)。化療港併發症發生的中位時間為化療港放置後的3個月。結合Clavien–Dindo分級方法,我們將化療港相關的併發症分為 1 - 4個等級。進一步分析發現,ECOG 評分 (OR 1.74; 95%CI 1.12-2.69)、白蛋白水平 (OR 3.67; 95%CI 1.96-6.86)、化療港放置方式是否優化 (OR 0.33; 95%CI 0.18-0.61) 及是否專業團隊放置 (OR 0.37; 95%CI 0.20-0.69) 為化療港併發症發生的獨立危險因素 (P < 0.05)。而且,ECOG 評分為併發症分級的相關因素 (P=0.016)。
結論: 腹腔化療港在胃癌腹膜轉移患者腹腔化療中的應用安全可行,相關的併發症可控。ECOG評分、白蛋白水平、化療港放置方式是否優化及是否專業團隊放置為化療港併發症發生的獨立危險因素。
