Quantitative analysis of the oral complications of antileukemia chemotherapy.

Almost half of 1500 patients (46.9%) treated for acute leukemia developed chemotherapy-related oral infections, oral mucositis, and/or oral hemorrhages at some time during their hospitalization. The frequencies of 34.2% for infections, 16.3% for mucositis, and 13.6% for hemorrhages were each within 1.3% to 3.1% of those previously reported from this institution for smaller groups of patients. The stomatologic disruptions reflected the cytotoxic, myelosuppressive, and immunosuppressive properties of the antileukemia drugs. Because there are as yet no alternatives to the use of potent stomatotoxic drugs for the treatment of acute leukemia, it is essential that their side effects be kept to a minimum by early recognition and appropriate treatment.
