The relationship of cellular immunity to prognosis in acute leukemia.
Forty-five patients with acute leukemia were compared on cellular immunity measures versus prognosis. The patients were treated according a multicombination therapy protocol. The purified protein derivative (PPD) test and dinitrochlorobenzene (DNCB) test on admission indicated low positive percentages. In acute non-lymphocytic leukemia (ANLL) patients, the 50% survival durations were 11 months in the PPD positive group and 6 months in the PPD negative group. In acute lymphocytic leukemia (ALL) patients, the 50% survival durations were 21 months in the PPD positive group and 13 months in the PPD negative group. Peripheral lymphocyte blastogenesis by phytohemagglutinin (PHA) stimulation was examined at various clinical stages. The stimulation indices were generally low, and no correlation was found between the PHA test and clinical stages. These cellular immunity measures appeared to reflect one aspect of the clinical condition in acute leukemia patients, and further studies are needed for predicting prognosis.
