目的:探索胃癌在手术、化疗前后无证可辨与临床因素的相互关系,以期指导临床。方法:通过对2004年-2008年期间634次胃癌住院患者在手术、化疗前后病案的回顾性调查和466人1097次胃癌手术、化疗前后患者的前瞻性调查,其中前瞻性调查以胃癌无证可辨为因变量,以相关临床因素为自变量进行logistic回归分析。结果:在回顾性调查和前瞻性调查中无证可辨发病率分别为22.17%和16.77%;从logistic回归分析来看,呈正相关:外科切缘、化疗次数;呈副相关:年龄、卡氏评分、术前化疗前或化疗间歇期服用中药。结论:调查时段不同,无证可辨发病率,临床影响因素也不同。
Objective: To explore the relationship between undifferentiated and clinical factors of gastric cancer before and after surgery and chemotherapy, in order to guide the clinical practice. Methods: A retrospective survey of 634 inpatients with gastric cancer during 2004-2008 before and after surgery and chemotherapy and 467 patients with 1097 gastric cancer surgery and chemotherapy before and after chemotherapy were prospectively investigated. Among them, the prospective investigation with no evidence of gastric cancer Identified as dependent variables, the relevant clinical factors as independent variables logistic regression analysis. Results: In the retrospective survey and prospective investigation, the incidences of undocumented identifications were 22.17% and 16.77%, respectively. Logistic regression analysis showed a positive correlation between surgical margins and the number of chemotherapy, and was correlated with age, Score, preoperative chemotherapy or intermittent use of traditional Chinese medicine. Conclusion: The investigation period is different, the incidence of undocumented discernible, clinical factors are also different.
