title: The cytopathology of bone marrow transplantation.
abstract: Bone marrow transplantation (BMT) is an increasingly effective treatment for patients with hematologic disorders and malignant neoplasms. From 1975 to 1986, 1,457 specimens were obtained for cytologic evaluation from 328 of the 635 patients who received BMTs at Memorial Sloan-Kettering Cancer Center. These specimens consisted of 1,049 cerebrospinal fluids (CSFs) from 265 patients, 292 bronchoscopy specimens from 92 symptomatic patients and 116 other specimens (including brushings from the liver and gastrointestinal tract, sputa, urines and cervico-vaginal smears). CSF specimens examined before and after BMT from 80 (30%) patients showed an increased number of benign, nonepithelial cells, which were mainly lymphocytic or histiocytic in origin. Malignant cells were detected in CSF specimens from 44 (17%) patients. Bronchoscopy specimens from 3 patients had suspicious cells present; those from 27 patients contained opportunistic organisms. Atypical epithelial or lymphoreticular cells were seen in bronchial specimens from 49 patients. All cytologic findings were correlated with the pertinent clinical information as well as biopsy and autopsy material, including histopathologic evidence of graft-versus-host disease. Cytologic evaluation, especially of bronchial and CSF specimens, was useful in diagnosing the presence of malignant neoplasms, infectious organisms, inflammatory responses, reactive lesions and cellular atypia due to treatment.
