BACKGROUND. In gastric cancer, the results of Intergroup 0116 trial showed a benefit for adyuvant chemoradiotherapy after radical surgery. However, in 53% of this group of patients the lymphadenectomy had been D0 (less than D1). Controversy exists as to whether the results of this study can be applied to our patients. MATERIAL AND METHODS. We have conducted a retrospective multicentric analysis including patients with gastric cancer who have received adyuvant treatment with the IT-0116 regimen after complete resection. We analyze patients characteristics, the extent of lymph-node dissection, the number of cycles administered and toxicity. RESULTS. Thirty one patients were analyzed. 26% of the patients underwent a D0 dissection. A D1 lymphadenectomy or a lymphadenectomy between D1 and D2 were performed in 12 patients (39%) and a D2 in 9 patients (29%). 2 patients were splenectomized. The median number of nodes analyzed were 12 (2-38). 90% of the patients had positive-nodes. There were 23 patients evaluables for treatment toxicity. 17 patients (74%) completed treatment as planned. 7 patients (32%) developed hematologic toxicity grade 3-4 and 20% grade 3 diarrhea. The dose-intensity of fluorouracil was 83%(64-100%). CONCLUSIONS. We have less patients with a D0 lymphadenectomy in our hospitals than in the Intergroup trial. We will make a survival analysis after a longer follow-up.
