Adjuvant chemoradiation has become a standard of care in the USA. We evaluated the efficacy and toxicity of adjuvant chemoradiation versus chemotherapy in completely resected locally advanced gastric cancer.


Patients with stage IIIA, IIIB and IV (without metastasis) gastric cancer were treated with chemoradiation and 5-fluorouracil/cisplatin (FP) (arm A) or FP (arm B). Arm A consisted of one cycle of FP followed by 4500 cGY to radiation field with capecitabine. One month after completion of radiotherapy, patients received three additional cycles of FP every 3 weeks. Arm B consisted of six cycles of FP.


A total of 61 patients were enrolled, of whom 31 were placed in arm A and 30 in arm B. The median follow-up duration was 77.2 months (range 24-92.8 months). We did not find any difference in 3-year disease-free survival between arm A and B (80.0 vs 75.2%, respectively; P = 0.887). There was no significant difference between the arms in 5-year disease-free survival (76.7 vs 59.1%, respectively; P = 0.222) or overall survival (70.1 vs 70.0%, respectively; P = 0.814). Seven patients (22.6%) relapsed in arm A and 12 patients (40%) relapsed in arm B. Grade 3/4 neutropenia occurred in 48.5% of patients in arm A and 22.9% in arm B. Grade 3 nausea or vomiting occurred in 6% in arm A and 14.6% in arm B.


  We could not make any conclusion about the benefit of adding radiation to adjuvant chemotherapy.
