title: Bacteremic infection and malnutrition in patients with solid tumors: investigation of host defense mechanisms.
abstract: Eighty-five patients with solid tumors without neutropenia were studied in order to determine host characteristics associated with bacteremic infection. Twenty patients without neoplastic disease who had bacteremia served as controls. Bacteremia frequently occurred in patients with tumors of the gastrointestinal and urinary tract, who were over 51 years of age, and had evidence of malnutrition. Peripheral blood lymphocyte dysfunction in vitro was commonly noted in infected patients with cancer. Polymorphonuclear leukocyte (PMNL) dysfunction was common in older bacteremic patients with and without cancer. The PMNL abnormality appeared to be cellular, it was not corrected with use of pooled normal serum, and was manifested by poor uptake of the assay organisms.
