Abstract
Prospective surveillance of hospitalized patients with leukemia or solid tumors was performed in order to define the rate of nosocomial bloodstream infection according to specific diagnosis. During the 38‐month study, there were 842 nosocomial bloodstream infections in 704 patients, 22% of whom had leukemia or solid tumors. In the patients with malignancy, the diagnoses associated with the highest rate of bloodstream infections were chronic myeloid leukemia (18.4/100 patients), acute lymphocyte leukemia (17.7/100), promyelocytic and undifferentiated leukemia (16.1/100) and acute monocytic/myelomonocyte (13.8/100). In 76% of patients with chronic lymphocytic, chronic myeloid, or undifferentiated leukemia, the peripheral blood polymorphonuclear leukocyte count at the time of bacteremia was ≤100 cells/mm−3. In contrast to patients with leukemia, those with solid tumors, as a group, were at no greater risk of bloodstream infection than those without malignancy. In preparation for prophylactic trials of antibiotics or immunotherapy this study has more clearly defined the risk of bloodstream infection in cancer patients. Cancer 50:187–190, 1982.
