Preoperative chemoradiation therapy for upper gastric cancer：a retrospective study for its efficacy and safety / 中国肿瘤临床

ABSTRACT

Objective:To investigate the efficacy, safety, and overall survival of advanced upper gastric cancer patients who received preoperative chemoradiation therapy. Methods:A total of 62 patients who received preoperative chemotherapy or chemoradiation therapy in the Department of Gastrointestinal Surgery of Beijing Cancer Hospital&Institute were retrospectively observed to determine the efficacy and safety and to perform survival analysis of preoperative chemoradiation therapy. Results:Results of the postoperative pathology showed that the number of patients with T4 and N3 stages was significantly lower in the preoperative chemoradiation therapy group than in the preoperative chemotherapy group (P<0.05). In addition, the differences between the two groups in terms of safety and toxicity were not significant (P≥0.05). Analysis also showed that the differences between the two groups in terms of survival were not significant (P≥0.05). Conclusion:Patients with advanced upper gastric cancer can gain a potential survival advantage from preoperative chemoradiation therapy. Compared with preoperative chemotherapy, preoperative chemoradiation therapy was performed without increased risk of toxicity and insecurity. Preoperative chemoradiation therapy can also improve the local control ratio, especial y the control ratio of lymphatic metastasis. However, the final results of survival analysis depend on long-term follow-up of patients.
