SummaryPraeperitoneal administration of colloidal 198Au complicating the treatment of anascitic ovarian cancer is reported. Typical scintiscans and various clinical findings of muscle necrosis and radiation myositis are described. Administration of larger amount of saline solution preceding the radiogold instillation controlled by simultaneous scintiscanning are suggested as safety measures in patients when no ascitic fluid is present.

Ovarian cancer (OC) is able to develop implantation metastases in the abdominal cavity. Ascites is potentially useful for evaluating cancer features. The aim of the study was to assess the content of stem-like tumor cells and inflammatory mediators in ascites of OC. The prospective study included 11 patients with primary OC having ascites, 8 patients with benign ovarian tumors having ascites and 22 healthy women. In ascitic fluid obtained by laparocentesis, the populations of tumor stem-like cells were determined on a Cytoflex S` flow cytometer (Beckman Coulter, USA) and CytExpert Software using monoclonal antibodies to CD45, CD44 and CD133. The cytokine profiles of ascitic fluid and blood serum (IL-1β, IL-18, IL-4, IL-10 and VEGF) were assessed by ELISA. Stem-like cells were found in all samples. 5 cell populations were evaluated. The number of cells expressing both markers: CD44 + and CD133+, was the lowest. The highest, about 32%, was the number of CD44+ cells. The number of cells CD45-CD44+CD133- in ascites strongly positively correlated with the content of IL-10 in ascites, and the numbers of CD45-CD133+ and CD45-CD44-CD133+ - with the level of VEGF in blood serum. No correlations were found between the numbers of stem-like cells and the disease stage or the level of CA125 in blood. The combination of IL-4 and IL-10 in ascites had the greatest significance in predicting the disease stage. These results suggest a relationship between the levels of VEGF, IL-10, and cancer stem cells in the OC ascites. Stem-like cells in OC ascites are heterogeneous and are present even at an early stage of the disease. It seems promising to study cell populations and cytokine profile of ascites together, to assess the biomarker potential of their combination.

Advanced Epithelial Ovarian Cancer

Abstract This study was undertaken to determine if advanced epithelial ovarian cancer was associated with increased serum and ascitic levels of soluble interleukin-2 receptor alpha (sIL-2R alpha). Serum and ascitic fluid samples from 23 ovarian cancer patients were analyzed for sIL-2R alpha using an enzyme-linked immunosorbent assay and compared with the serum and peritoneal levels in 18 normal females. The samples were analyzed for CA-125 levels using a radioimmunoassay and the total protein was also measured. Normal individuals had low serum levels of sIL-2R alpha (367.5 +/- 44.6 U/mL), with similar levels of sIL-2R alpha in the normal peritoneal fluid (438.6 +/- 48.8 U/mL). In contrast, the serum and ascitic fluid levels in ovarian cancer patients were significantly higher (746.7 +/- 82.9 U/mL, P = .0006; 2,656.7 +/- 373.7 U/mL, P = .00002, respectively). The results for sIL-2R alpha were also significant when the levels were expressed per milligram of total protein. More importantly, in almost every ovarian cancer patient the ascitic sIL-2R alpha level far exceeded the serum level, a pattern also observed for CA-125. There was no correlation between the serum and ascitic sIL-2R alpha levels, or between the serum and ascitic CA-125 levels. Although the serum levels of sIL-2R alpha and CA-125 were elevated in the same patient, overall there was no correlation between the serum sIL-2R alpha and serum CA-125 levels, either when the levels were expressed in absolute units or per milligram of total protein. Similarly, there was no correlation between sIL-2R alpha and CA-125 levels in individual ascitic samples. While CA-125 levels may reflect an independent index of tumor burden, these results suggest that selective accumulation of sIL-2R alpha in the ascites may be one of the factors associated with the known nonresponsiveness of the infiltrating lymphocytes against ovarian carcinoma cells.

Crosslinked fibrin has been demonstrated by immunohistochemi-cal tests to occur around tumor plugs, on the surface and in the stroma of the tumor in ovarian cancer. High levels of D-Dimer (200-800μg/ml), the characteristic terminal degradation product of crosslinked fibrin, are found in ascitic fluid of patients with advanced ovarian cancer. These findings suggest that fibrin polymerisation and degradation are related to and even may influence tumor growth. The kind of proteases which are responsible for degradation of crosslinked fibrin is, however, unknown.lt was the aim of this study to evaluate whether plasmin and/or other proteases are involved in tumor-associated fibrinolysis. Therefore the total high-molecular-weight fibrin degradation products in ascitic fluid were purified by protamine sulfate precipitation, gel filtration, immunoadsorption and compared with the components of plasmin-degraded crosslinked fibrin, i.e. DD,DY,YX,DXD and DXY, by direct SDS-PAGE in the absence of mercaptoethanol and after excision of the bands, mercaptolysis and re-electrophoresis. Pronounced similarity between the two sets of fragments was observed. For further information the fragments from the two sources were mercaptolysed and their polypeptide chain components separated by reversed-phase high-performance liquid chromatography, the components being identified by N-terminal sequence analysis and SDS-PAGE. Highly similar patterns were obtained and components corresponding to γ-γ ,γ-γ1, β, β2 and α1 could be recognized. The findings provide strong evidence for plasmin being the primary protease involved in ovarian carcinoma-related fibrinolysis, (supported by Deutsche Forschungsgemeinschaft.SFB 207, A2).

PURPOSE The clinical impact of endogenous cytokines supplied with deterministic properties in the generation of either T helper (Th)1 -type or Th2-type immune response was investigated in patients with ovarian cancer. Whereas interleukin (IL)- 12 initiates the differentiation of naive Th0 cells toward Th1 phenotype, IL-4 and IL-10 mediate the development of Th2-type immunity. PATIENTS AND METHODS Cytokines were determined before treatment by means of enzyme-linked immunosorbent assay (ELISA) in ascites fluid and serum of 76 patients with ovarian cancer. Cytokine levels were compared with each other and with standard clinicopathologic parameters. A stepwise logistic regression was calculated to rule out interdependence in the associations of the various variables. Survival analyses were performed with the Kaplan-Meier method and differences in survival were examined according to Mantel and Breslow. Cox proportional hazards analysis was used to identify independent prognostic factors. RESULTS Whereas IL-10 and IL-12 were detectable in all ascites-fluid samples, IL-4 was measurable in only 43% of the specimens. With the exception of neopterin, macrophage colony-stimulating factor (M-CSF), and IL-4, determined cytokine levels were significantly elevated in ascites fluid compared with serum (P < .01). In univariate analyses, high ascitic-fluid concentrations of either neopterin, tumor necrosis factor-alpha (TNF-alpha), or IL-12 were associated with poor disease-free (P < .005) and overall (P < .01) survival. Multivariate Cox regression analysis showed ascitic-fluid IL-12 levels to be the only immunologic variable that retained independent prognostic significance (P < .03 for disease-free and P < .01 for overall survival), together with residual disease, Fédération Internationale de Gynécologie et d'Obstétrique (FIGO)-stage, and patient age. CONCLUSION In ovarian cancer, high ascitic-fluid IL-12 levels, which may indicate a local Th1-generated immune response, are associated with disease progression.
