[A case of complete remission following recurrent relapses 12 years after onset of acute myelocytic leukemia. Response to protocol including neocarzinostatin].
A 23-year-old male who had suffered recurrent relapses of acute myelocytic leukemia was treated with a protocol including neocarzinostatin (NCS) and complete remission was obtained. At the age of 11 years, he had complained of general fatigue and anemia, and was diagnosed as having AML because of the presence of leukemic cell infiltration in the bone marrow as well as peripheral blood. Auer bodies and a positive reaction to peroxidase were found. The last episode of relapse occurred at the age of 15 years, when he achieved complete remission following a trial protocol which included NCS. NCS seemed to be effective after it had been used intravenously for a short time. The patient has maintained complete remission for the past 7 years and has had no consolidation therapy in the last 3 years. For the last 18 months, he has been working in a market as a clerk 8 hours a day. NCS with a rapid infusion time seems to have effects on leukemic cells when it used with proteolytic enzyme. Neither skull radiation nor testicular biopsy were attempted. Results of CSF examination were within normal limits, but EEG and CT scan revealed the probability of early-stage leukoencephalopathy, although no significant clinical signs were observed. He had suffered an asthmatic attack before the onset of AML, but no further attack occurred until several months ago. In order to establish any relationship between these two diseases, further detailed analysis will be necessary.
