Abstract
7075 Background: AML is a disease of old age, but unfortunately due to several factors standard treatment can not be delivered to these patients. Here we tried to achieve to bet possible response to these patients. Methods: Eleven old age patients selected for this trial. Patients couldn't tolerate standard treatment of AML due to old age or comorbid disorders. Treatment consist of best supportive care plus administration of low dose ARA-C (20mg/day as SQ) for 10 days each months and arsenic trioxide 10 mg/day as 2 hour iv infusion each month. Patients followed by CBC and BMA/B when peripheral blood normalized or every other month. Results: This cohort consist of 8 men and 3 women. Median age was 75 y/o (55–80). Median WBC count Hb level and platelet count at presentation were 42,860μl, 8.3g/dl and 30,500/μl, respectively. Complete remission observed in 6 and partial remission in one patient (RR = 63.6%), but remission was short live, after 6 months one patient was in CR and one in PR. After 12 months, only one patient was in PR. Median survival was 6 months and 6 patients survive more than 6 months. Two patients are alive after 12 months. Conclusions: Although prognosis of old age AML remain poor, but with this type of treatment RR is acceptable. In this very high-risk group of very old AML, combination of ATO and ARA-C possibly could improve survival. No significant financial relationships to disclose.
