Alpha-hemolytic streptococci: clinical significance in the cancer patient.
Alpha-hemolytic Streptococci were associated with 29 episodes of sepsis (12 polymicrobial) in 27 patients with cancer during a nine year period. Only two patients had dental manipulation prior to the onset of sepsis, but each had received chemotherapy and 75% were granulocytopenic (PMN less than 500/mm3) at the time of the infection. None of the patients developed bacterial endocarditis. Unlike the normal host in whom a transient bacteria with alpha-hemolytic Streptococci may occur following dental extraction or periodontal procedures, the cancer patient is at risk for more clinically significant sepsis. This risk is probably related to the presence of chemotherapy-induced oral mucusitis and granulocytopenia, and our results suggests that isolation of alpha-hemolytic Streptococci in febrile cancer patients should not be dismissed as a contaminent.
