Metastatic carcinoma in histologic sections of aspirated bone marrow: a comparative autopsy study.

The incidence of metastatic carcinoma in bone marrow was studied by two different approaches in 220 consecutive autopsies of patients with carcinoma: histologic sections of aspirates from the iliac spine, as usually done in living patients; and gross and microscopic examination of the thoracolumbar spine. Ten percent of the autopsies showed bone marrow metastases by the aspiration technic as contrasted with 34.5% by the autopsy technic. Three cases had positive bone marrow aspirates in the absence of metastases demonstrable by routine autopsy. The combination of autopsy and aspiration technics yielded an incidence of metastatic marrow involvement of 35.9%. Of patients with marrow metastases at autopsy, 25% also had positive aspirates. This study establishes a norm for the comparison of the efficiency of discovery of metastatic carcinoma by different modalities of clinical bone marrow sampling.

A correlative cytohistologic study on the interrelationship between exfoliated urinary bladder carcinoma cell types and the staging and grading of these tumors.

The purpose of this sutdy was to demonstrate the existence of a certain correlation between the type of exfoliated malignant tumor cells (transitional and/or epidermoid) in 28 bladder tumor cases, and the stage of these tumors as evidenced in histologic sections of full-depth bladder biopsies or cystectomies. This investigation permitted not only correlation of the type of malignant cells with the stage but also with the grade of these tumors. However, this study should be followed by more investigations based on quantitative analyses or cytomorphometric approaches in order to reach more definitive results.

The diagnostic reliability of cytologic typing in primary lung cancer with a review of the literature.

To evaluate the growing tendency in recent years to attribute more diagnostic reliability to cytologic methods, we investigated the accuracy of cytologic typing in specimens obtained from bronchopulmonary material by five different clinical sampling methods, comparing the cytologic diagnoses with the known histologic diagnoses. The study consisted of 232 cytologic specimens from 157 cases of primary lung cancer. Of the 232 specimens, 173 (75%) were correctly typed and 59 (25%) incorrectly typed with respect to the appropriate histologic diagnoses. When all sampling methods were considered together, the study demonstrated that well-differentiated epidermoid carcinoma and "oat cell" and spindle-polygonal anaplastic carcinomas yielded high cytologic typing accuracies. In poorly differentiated tumors, bronchioloalveolar cell carcinoma and bronchogenic adenocarcinoma, the correct cytologic typing was much lower. The different tumor types and their degrees of differentiation seem to be the decisive factors in cytologic typing accuracy. The findings of this study were compared with those of others and were found to be consistent with the results of even larger series of cases. For some types the typing accuracy was higher than that reported in other series, whereas for other types, e.g., adenocarcinomas, it was lower.
