Short-time effects were valuable in 31 cases with PLC and 7 cases with LMC.Complete remission(CR)plus partial rimission(PR)ocurred in 14 cases(45.16%)among 31 patients with PLC and 1 case(14.28%)among 14 patients with LMC(P<0 .01).CR plus PR was 10cases(52.63%)among 19 patients with central type cancer (CTC)and 4 cases (33.33%) among 12 patients with perprephal type cancer(PTC) of PLC(P<0.05). CR plus PR in 15 squamous carcinomas(SC),6 adenocarcinomas (AC)2 small cell undifferentiated carcinomas(SCLC)and 8 histologically unclassfied carcinomas(HUC)were 8(53.33%),1(50%),and 3(37.5%), respectively.The rate of CR plus PR in squamous carcinoma was higher than that in adenocarcinoma and histologically unclassified carcinoma(P<0.05).There was no remarkable difference in CR plus PR among stage Ⅱ-Ⅲand Ⅳpatients with PLC, CAP and FMP protocol treatment.This study also investigated and analysed the side effects of 41 patients by BAI treatment.展开更多
