Twenty bone marrow aspirates harvested for autotransplantation from 20 patients suffering from several oncohematological diseases were processed using the automated Du Pont SteriCell processor. In 15 bone marrow harvests, the interface buffy coat cells were collected using the SteriCell processor in manual mode with a semiautomated procedure. The procedure yielded an average red cell removal of 84% and an average mononuclear cell (MNC) recovery of 86%. Cloning efficiencies of hematopoietic progenitor cells (CFU-GM and BFU-e) did not differ between processed and recovered MNCs. Four cryopreserved bone marrow buffy coats were thawed and reinfused into four patients who had undergone high dose chemotherapy. Stable engraftment was observed in all cases. In five bone marrow harvests, the SteriCell automated density gradient MNC isolation procedure was performed after buffy coat collection. The whole two-step procedure allowed an average MNC recovery of 69%. CFU-GM and BFU-e assays did not show a significant difference in cloning efficiency between processed and recovered bone marrow MNCs. We conclude that the SteriCell processor offers rapid, safe and feasible procedures for the semiautomated processing of human bone marrow for transplantation. The clinical efficacy of density gradient separated bone marrow employing the automated step and the opportunity to use fully automated processing must be investigated.

Between March 1986 and March 1989, 65 epithelial ovarian carcinomas were studied by means of real time high resolution ultrasound. The sonographic findings were correlated with FIGO stage, histotype and histological grade. The echostructure was compared with that of a group of 141 benign controls. Moreover, some sonographic patterns, significantly more frequent in the malignant tumors (ascites, irregular borders, peritoneal growths), were identified. The diagnosis of malignancy was as accurate as 90.0%, sensitivity and specificity were 84.7% and 92.3% respectively. Our results, coupled with the low costs involved and the non-invasiveness of the method, thus confirm that ultrasound can still be considered a primary technique in the preoperative assessment of ovarian masses.

An unusually large Sertoli cell adenoma was detected in a patient with Morris syndrome and there is a description of the uncommon hormonal data found in this particular case which are not typical for this kind of neoplasia. The patient is alive and well at the present time which is now three years after surgical intervention.
