Abstract:
To achieve the complete remission (CR), acute leukemia (AL) patient must get through the period of myeloid ablation after chemotherapy that the white blood cell (WBC) count in peripheral blood decreases rapidly. To observe the relationship of WBC count with therapeutic effectiveness after chemotherapy in previously untreated AL, eighty cases of previously untreated acute leukemia who took the first induction chemotherapy course were analyzed. Blood routine was carried out 2 to 3 times every week while the bone marrow pictures on 12th and 20th day after chemotherapy were observed. 80 patients were divided into 3 groups based on the lowest value of WBC count after chemotherapy: 0.9 x 10(9)/L group. The results showed that the complete remission rates after the first course of chemotherapy were 60 vs 55.6 vs 27.3% respectively in the three groups which WBC counts were 0.9 x 10(9)/L. The total efficaciousness rates were 90 vs 92.6 vs 66.7 respectively in the three groups. The efficaciousness rate of the first two groups significantly differed from the third group (P < 0.01). However, no significant difference was shown between the first and second groups. It is concluded that the leukocyte count after the first course of chemotherapy may be an early indicator to predict the efficaciousness of chemotherapy.
