Objective: To investigate the clinical features of senile acute leukemia. Methods: The clinical data of 22 elderly patients with acute leukemia were summarized. Results: The clinical manifestations and hematological changes in elderly patients with acute leukemia were mostly atypical and easily misdiagnosed. Except for the loss of follow-up or pre-chemotherapy death (13 cases), the patients were treated with DA, COA, COP and low dose of cytarabine , Complete remission in 2 cases (with DA and other programs), partial remission in 3 cases, 4 deaths. CONCLUSION: The clinical manifestations and hematological changes of atypical leukemia are not typical, which affects the early diagnosis. The prognosis is poor. Small doses of chemotherapy can be used according to the above scheme to prolong the survival period.
