[Treatment of chronic myelogenous leukemia (CML)--VP(M) regimen starting during its chronic phase, and the second nation-wide survey on the long-term survivors of CML in Japan].
Eighty-three patients in the chronic phase of Ph1-positive chronic myelogenous leukemia (CML) have been treated with busulfan or other alkylating agents in a conventional way hitherto acknowledged. During its chronic phase, 31 cases of these 83 had received an additional intermittent therapy every 4 to 6 months, consisting of vincristine 2 mg or vindesine 3 mg per week, prednisolone 20 to 30 mg per day, and partly 6-mercaptopurine 50 to 100 mg, combined with allopurinol 200 to 300 mg per day for 2 to 3 weeks. The 50% survival of these patients using the Kaplan-Meier's method was 73, 7 months and 5-year survival was 70.2%, while those of the remaining patients were 41.2 months and 13.4%, respectively. The second nation-wide survey of long-term survivors of CML in Japan was attempted. CML totalling 195 surviving over 7 years from the initial diagnosis and 113 of CML surviving over one year from the blastic crisis had been collected by the end of March 1988. The longest survivors of the former group was for 21.3 years, while the latter 4.6 years. In addition, recent increase of the annual incidence of the above both groups was clarified. These results strongly support the progress of chemotherapy of CML in recent years.
