The gold standard of adjuvant treatment after surgical resection of adenocarcinoma of the stomach or gastroesophageal junction (GEJ) is chemoradiotherapy. We retrospectively evaluated chemotherapy without radiotherapy in stomach and GEJ adenocarcinoma, using a combination of etoposide, adriamycin and cisplatin (modified EAP). Sixty-five patients with completely resected gastric or GEJ adenocarcinoma and positive regional lymph nodes were treated with modified EAP over an 8-year period. Recurrent disease was diagnosed in 38/58 (69%) patients evaluable for analysis. Only two (5%) had locoregional recurrence. The main toxicity was hematological, with 22 (34%) patients developing neutropenic fever and 12 (18%) anemia requiring blood transfusion. The median survival for the entire group was 20 months, with a median time to recurrence of 11 months. Seventeen (26%) patients are alive for a median of 7+ years, with no evidence of recurrent disease. Our data cast doubt on the benefit of radiotherapy adjuvant to chemotherapy.
