Abstract

Nonfunction of a Leveen shunt was diagnosed in a 53-year-old cirrhotic woman by lack of lung visualization following intraperitoneal administration of Tc-99m MAA, despite imaging of the shunt tubing itself. Surgery confirmed the malfunction and follow-up study after surgical correction showed normal function. Using intraperitoneal injection, an end-organ must be seen to confirm shunt function. The method of Rosenthall et al may provide a more rapid diagnosis of nonfunction without the necessity of end-organ imaging.

Human ovarian epithelial cancer cells cultures in vitro express both interleukin 1 alpha and beta genes.

Ascitic fluid from human ovarian cancer patients often contains a large number of leukocytes along with tumor cells. Some of the recent evidence suggests that the ascitic fluid contains factors capable of inducing the growth of ovarian cancer cells in vitro and in vivo. While these factors have not yet been completely characterized, growth factors secreted by the tumor cells could influence the tumor growth by paracrine and autocrine mechanisms. Earlier, we reported that ovarian epithelial cancer cells produce macrophage colony-stimulating factor. It appears that these tumor cells produce more than one cytokine. Identifying the various products secreted by the tumor cells would provide valuable information needed to understand the biology of ovarian cancer. In the present study, evidence is provided for the first time that five different human ovarian epithelial tumor cell lines and tumor cells isolated from the ascitic fluid of four cancer patients express interleukin (IL) 1 alpha and beta genes constitutively. Production of the lymphokine was determined by analyzing the cellular RNA for IL-1-related transcripts and by immunological assays. Ovarian cancer cells also secrete another pleiotropic cytokine, IL-6, constitutively. In many systems, IL-1 induces the expression of the IL-6 gene. To determine whether the basal levels of IL-6 production are dependent on the endogenous IL-1, neutralization studies were carried out. Addition of antibodies to IL-1 did not decrease the levels of IL-6 secreted by the cancer cell lines. These results suggest that multiple cytokines are produced by ovarian cancer cells and that the endogenous IL-1 may not be directly involved in the regulation of IL-6 gene expression in these cells.

Peritoneal washing cytology in women: diagnostic pitfalls and clues for correct diagnosis.

The significance of peritoneal washing cytology in the management of patients with gynecologic cancer is well established. Its microscopic evaluation, however, is not always straightforward. Previous studies have identified some of the conditions that may result in misinterpretation of cytologic results. This report reviews the literature and describes other sources of diagnostic difficulties and clues for correct diagnosis. In addition, an outline for distinguishing endosalpingiosis from borderline and well-differentiated serous carcinoma is proposed.
