RESUMO

BACKGROUND: Distant tumor metastases in ovarian cancer patients in striated muscles are extremely rare. So far, only one case of metastatic but asymptomatic spread to striated muscle has been described. CASE: A patient with recurrent ovarian carcinoma presented with a gluteal mass 1 week following optimal debulking surgery. CT and MRI initially suggested muscle necrosis or intramuscular bleeding. Increasing pain and massive lymphedema led to immobilization and clinical deterioration. Repeated ultrasound and CT-guided biopsy confirmed the diagnosis of skeletal muscle metastases. CONCLUSION: This is the first case description of distant skeletal muscle metastasis as the leading clinical symptom of late stage ovarian carcinoma. It reveals possible limitations of CT and MRI as diagnostic tools for early identification of striated muscle metastases.

RESUMO

OBJECTIVE: This study was performed to examine whether an improvement in the transvaginal sonographic evaluation of the endometrium is possible by the addition of sonomorphological criteria to the measurement of endometrial thickness in women with postmenopausal bleeding. METHODS: Various sonomorphological criteria were analyzed prospectively in 321 patients with postmenopausal bleeding. In a logistic regression model relevant criteria were selected and a diagnostic formula for differentiation of endometrial sonographic findings was derived. RESULTS: The criteria of endometrial structure, endometrial-myometrial border and endometrial thickness were significant for the differentiation of malignancy. These results allowed an estimation of the probability of malignancy for each sonographic endometrial finding. Using the cut-off point of 0.1 for the probability of malignancy, the sensitivity and specificity were 96.8% and 61.9%, respectively, with an accuracy of 72.3%. In contrast, the differentiation by endometrial thickness as the sole criterion (cut-off point > or = 5 mm) achieved a sensitivity of 97.9% and a specificity of 33.2%, with an accuracy of 52.3%. CONCLUSION: A useful diagnostic formula based on sonomorphological and metric criteria for endometrial differentiation was obtained. The specificity and accuracy increased with a minimal loss of sensitivity. However, estimates for sensitivity, specificity, and accuracy may be overoptimistic because they were derived from the same data used for development of the model.

RESUMO

The human papillomavirus type 18 (HPV-18) upstream regulatory region (URR) controls cell type-specific expression of the viral oncoproteins E6 and E7. The HPV-18 URR is active in the cervical carcinoma cell line HeLa but inactive in the hepatoma cell line HepG2. C/EBPss (NF-IL-6) was shown to participate as an important regulator in HPV transcription dependent on the cell type. The finding that C/EPBss is critical for HPV-18 URR activity and that C/EPBss is induced by IL-6 offers the opportunity of manipulating HPV activity by specific cytokine treatment. In this report, we show that treatment with IL-6 results in activation of HPV-18 URR activity in HepG2 cells. In contrast, the HPV-18 URR is not inducible by IL-6 in three cervical carcinoma cell lines. In all three cell lines we found decreased expression of the IL-6 receptor compared to the IL-6-responsive HepG2 cells, whereas the level of expression of the signal transduction component gp130 is present in all cells. These results suggest that cervical carcinoma cells may circumvent the IL-6-induced cellular defense mechanism through downregulation of the IL-6-receptor.
