Combination chemoimmunotherapy for advanced gastric carcinoma.
Eighty-nine patients with advanced gastric carcinoma were treated with a combination chemo-immunotherapy regimen that consisted of active immunotherapy with Vibrio cholerae neuraminidase (VCN) treated autologous tumor cells admixed with BCG and drugs including cyclophosphamide, mitomycin C (MMC) and 5-fluorouracil, followed by long term tegafur (FT) and immunomodulators. This treatment significantly improved survival rate of patients in Stages III, IV and unresectable or recurrent carcinoma, compared to that of historical controls. As compared to controls treated with MMC followed by long term FT and immunomodulators concurrently, survival rate of those in Stage III tended to improve (P less than 0.1) and survival rate at 4.5 years in Stage III was significantly higher (p less than 0.01), although it was not improved in Stage IV. In patients with unresectable or recurrent tumor, survival time was not significantly lengthened with this therapy when compared with that in patients given BCG alone in the same treatment schedule (CCI-BCG group). However, none of 19 patients in CCI-BCG group survived more than 15 months, although 4 of 28 patients receiving this therapy survived. These results suggest that this combination chemo-immunotherapy is effective for a selected group of patients with advanced gastric carcinoma.
