Increased morbidity associated with oral infection in patients with acute nonlymphocytic leukemia.

The proper dental management of patients with leukemia is complicated by the compromised host defenses against infection. This compromised state is a result of the chemotherapeutic agents used in cancer treatment as well as the natural existing disease state. Infection remains the leading immediate cause of death in persons with leukemia. Previous reports have described oral complications secondary to this neoplasm and its medical management; however, relatively few studies of the incidence of systemic complications secondary to oral disease have been reported. This study analyzed the incidence of acute infectious episodes in patients with acute nonlymphocytic leukemia (ANLL). Thirty-eight patients were randomly selected for review; of these patients, twelve (32 percent) had identifiable acute oral infection associated with the presence of a febrile state (greater than 101 degrees F). Seven of the twelve (58 percent) had no other identifiable sources of infection. The periodontium was the oral site most frequently involved, followed by mucosal and periapical loci. Most acute oral infections were associated with profound granulocytopenia (less than 100/microliters). The data suggest that oral disease plays a clinically important role in the development of systemic complications in ANLL patients.
