对应用卡介苗免疫疗法（免疗）结合化疗取得完全缓解（ＣＲ）后复发之急性白血病患者２４例，继续以免疗加化疗再诱导缓解，就其经解率进行疗效观察。其中急淋１３例，急非淋１１例，符合难治性病例者１４例。治疗结果ＣＲ２０例、ＣＲ率８３．３０％。难治性病例ＣＲ１０例、ＣＲ率７１．４％。对照文献，单纯化疗对复治病例的ＣＲ率通常急淋＜７５％，急粒２５～５０％，说明免疗可以提高急性白血病复发病例的再缓解率。
Twenty-four patients with acute leukemia who relapsed after complete remission (CR) were treated with BCG immunotherapy (chemotherapy-free) combined with chemotherapy and continued to avoid remission induced by chemotherapy and chemotherapy. Of which acute leaching in 13 cases, acute non-leaching in 11 cases, in line with refractory cases in 14 cases. Treatment outcome of CR20 cases, CR rate was 83.30%. Refractory cases of CR10 cases, CR rate of 71.4%. In the control group, the CR rate of retreatment with chemotherapy alone is usually <75% and 25% ~ 50%, indicating that the treatment of remission can improve the rate of re-acute leukemia recurrence.
