摘要
In early gastric cancer, lymph node metastasis is known to be a prognostic factor. A retrospective study of 134 patients with submucosal gastric cancer (SMGC) who had undergone gastrectomy with lymph node dissection was performed to evaluate the prognostic factors and indication of postoperative chemotherapy. Five-year disease-free survival rate for 121 patients without nodal metasatasis was 100% with (n = 62) or without postoperative chemotherapy (n = 59), On the other hand, it was 72.9% for 13 patients with nodal metastases, although all patients had undergone D2 or D3 resection and received postoperative chemotherapy, Tumor recurrence occured only in three patients (n = 3) with alpha-fetoprotein (AFP) producing cancer and lymph node metastasis. Multivariate analysis with the Cox's proportional hazard model revealed AFP positivity to be a new independent prognostic factor in addition to lymph node metastasis in the patients with SMGC. Our findings suggest that routine use of postoperative chemotherapy does not appear rational for the patients without nodal metastasis and that new modalities of operation and chemotherapy may be necessary for the patients with AFP producing SMGC with nodal metastasis. The necessity of chemotherapy in conventional-type SMGCs with nodal involvement remains to be studied in future. (C) 1998 Academic Press.
