Tumor and node status was reclassified according to the 7th edition of the American Joint Committee on Cancer tumor-node-metastasis classification for carcinoma of the stomach. Survival data came from both the patients' follow-up records and telephone followups.Recurrent gastric cancer was diagnosed based on clinical imaging, gastroscopy with biopsy, and/or cytological examination of ascites, or intraoperative findings in patients who underwent reoperation.Predictors of early recurrence were compared in patients with pT1 and pT2-4a stage tumors. Pearson's χ 2 test and Fisher's exact test were used to compare differences between categorical variables. Survival curves were constructed using the Kaplan-Meier method and compared via the log-rank test. Variables identified as potentially important for early recurrence using univariate analysis were determined by multivariate logistic regression analysis.RESULTS: Of 417 gastric cancer patients, 80(19.2%)were diagnosed with early gastric cancer and the remaining 337(80.8%) were diagnosed with locally advanced gastric cancer. After a median follow-up period of 56 mo, 194 patients(46.5%) experiencedrecurrence. The mean time from curative surgery to recurrence in these 194 patients was 24 ± 18 mo(range, 1-84 mo). Additionally, of these 194 patients,129(66.5%) experienced recurrence within 2 years after surgery. There was no significant difference in recurrence patterns between early and late recurrence(P < 0.05 each). For pT1 stage gastric cancer, tumor size(P = 0.011) and pN stage(P = 0.048) were associated with early recurrence of gastric tumors.Patient age, pT stage, pN stage, Lauren histotype,lymphovascular invasion, intraoperative chemotherapy,and postoperative chemotherapy were independent predictors of early recurrence in patients with pT2-4a stage gastric cancer(P < 0.05 each).CONCLUSION: Age, pT stage, pN stage, Lauren histotype, lymphovascular invasion, intraoperative chemotherapy, and postoperative chemotherapy are independent factors influencing early recurrence of pT2-4a stage gastric cancer.展开更多
