[Pre- and intraoperative radiotherapy for locally advanced gastric cancer in conjunction with extended lymph node dissection: results of phase II clinical study].

The paper discusses our findings on a phase II clinical study of an original procedure for therapy of locally advanced gastric cancer including pre- and intraoperative radiotherapy (IORT) and extended lymph node dissection. Out of 24 patients, none had intraoperative complications while postoperative ones developed in 16%; lethality rate was 4%. As far as immediate results are concerned, intensive pre- and intraoperative radiotherapy proved fully compatible with any surgical procedure including extended and extended-combined ones. Survival rates (Kaplan-Meier) were: 1 yr--90 +/- 6%; 2-, 3-year--74 +/- 9%. Indications of adjuvant radiotherapy and approaches to its effective use are discussed.
