Acute nonlymphocytic leukemia following treatment of testicular cancer and gastric cancer with combination chemotherapy not including alkylating agents: report of two cases.

Acute nonlymphocytic leukemia following combination chemotherapy not including alkylating agents or radiotherapy was observed in one patient treated for testicular cancer and in another treated for gastric cancer. Both patients presented clinical, cytologic, and cytogenetic findings uncharacteristic for secondary acute nonlymphocytic leukemia. It is discussed whether these two cases of leukemia indicate a risk of secondary leukemia following chemotherapy with cisplatinum and adriamycin.
