[Neoadjuvant chemotherapy using TS-1 and CDDP against large type 3/Type 4/Bulky N 2 advanced gastric cancer].
This study was conducted to assess therapeutic results following neoadjuvant chemotherapy (NAC) for large type 3/type 4/Bulky N 2 advanced gastric cancer having a poor prognosis following resection. The subjects consisted of cases (< or = 75 y.o.) having large type 3 (diameter > or = 8 cm), type 4 or Bulky N 2 gastric cancer curable by resection based on preoperative imaging diagnostics. The NAC regimen consisted of TS-1 at 80-120 mg/body on days 1-21 p. o. and CDDP at 60 mg/m2 on day 8 divided. Upon completion of two courses of 4 weeks per course, gastrectomy with > or = D2 lymph node dissection was carried out on days 21-34. The average age of the subjects was 60.7 years, and the therapy completion rate was 80% (8/10 cases). Five of ten cases were responders diagnosed as grade 2 by histopathological examination of excised specimens (response rate 50%). Two of five responders were histopathologically evaluated as down-staging as a result of NAC (Stage III A--> f Stage I A, Stage IV--> f Stage I A). Three of the five non-responders have relapsed, and the relapse-free interval was an average 238 days. In the five responders,one has relapsed at 331 days,while the other 4 responders have shown no relapse yet. Although NAC consisting of TS-1 and CDDP is considered to be effective against advanced gastric cancer, a phase III study with surgical treatment only will be necessary to confirm its true value.
