Abstract

The aim of this study was to determine the efficacy and acute toxicity of our early experience with treating postoperatively non-metastatic gastric cancer with intensity-modulated radiotherapy (IMRT). A retrospective review was performed on 47 consecutive patients with gastric cancer and treated with postoperatively adjuvant IMRT at Department of radiation oncology, Zhejiang cancer hospital, China, between January 2007 and August 2009. One patient who did not complete his radiation course was excluded, leaving 46 patients for analyses. The median radiation dose delivered was 4500cGy using 180cGy fractions. Concurrent chemotherapy administered were 5-fluorouracil (n=36), capecitabine (n=9) and none (n=1). The median follow-up time was fifteen months (range 6-28 months). 1-year OS and 2-year OS were 98.0% and 80.0%, assessed by Kaplan-Meier methods. Of the six patients who died, five (83.3%) developed a distant metastases. The overall survival time by tumor size was significantly different (>6cm vs. =6cm, p<0.05). There was no significant survival difference between 5-fluorouracil group and capecitabine group (p=0.80). The data support the use of IMRT in the adjuvant treatment in high risk gastric cancer postoperatively. Acute toxicity is tolerable. Capecitabine with concurrent IMRT was as effective and tolerable as 5-FU/IMRT. Distant metastasis was the main reason of treatment failure that must be addressed in future trials.
