1/3. Hepatic resection of metastatic tumor from serous cystadenocarcinoma of the ovary.Metastatic carcinomas are the largest group of malignant tumors of the liver. But parenchymal liver metastasis from cystic ovarian adenocarcinoma is very rare. We report a case in which the resection of metastatic liver neoplasm from ovarian serous cystadenocarcinoma was done 7 yr after initial treatment. A 48-yr-old oriental housewife complained of easy fatigability and right lower quadrant discomfort. The hepatic mass was detected by ultrasonographic examination. serum albumin, bilirubin, and aspartate aminotransferase/alanine aminotransferase were normal. alkaline phosphatase level was slightly increased at 146 IU/L. A tumor marker study showed alpha-fetoprotein 0.97 IU/mL, carcinoembryonic antigen 0.965 ng/mL, cancer antigen 125 1,267 ng/mL and CA 19-9 106.1 ng/mL. The operation involved cholecystectomy and segmentectomy VI and VII of the liver. The patient recovered from the surgery without any complication. On the 10th postoperative day, the patient received a single-regimen chemotherapy with paclitaxel (Taxol, 155 mg/m(2) BSA) and was discharged. She has been carefully followed-up without any evidence of recurrence after completion of the remaining 5 cycles of chemo-therapy, at intervals of three weeks.- - - - - - - - - - ranking = 1keywords = antigen (Clic here for more details about this article) |
2/3. Hepatoid carcinoma of the ovary: a report of three cases admixed with a common surface epithelial carcinoma.Hepatoid carcinoma of the ovary is an ovarian carcinoma that has phenotypic properties in common with hepatocellular carcinomas. However, the extent of the tumor cells' similarity to and their difference from hepatocytes is largely unknown. In addition, the precursor cell of origin for hepatoid carcinoma of the ovary has not been identified. Three cases of alpha-fetoprotein-producing hepatoid carcinoma of the ovary that were admixed with an adenocarcinoma of common surface epithelial type are reported. The hepatoid carcinomas had a trabecular architecture with canaliculi detected by polyclonal (but not monoclonal) anticarcinoembryonic antigen antibodies. A hepatic phenotype in the hepatoid tumor cells was further supported by the production of albumin mRNA by in situ hybridization. The adenocarcinomas in the three cases were mucinous (Case 1), serous (Case 2), and endometrioid (Case 3), respectively. The cytokeratin (CK) profile in both the hepatoid and adenocarcinomatous components was CK18 /CK19 /CK20 /-, whereas normal and neoplastic hepatocytes were CK18 /CK19-/CK20-. Although this study supports a hepatic phenotype in ovarian hepatoid carcinoma, the CK profile of hepatoid carcinoma differs from that of normal and neoplastic hepatocytes but resembles that of the associated common epithelial adenocarcinoma. These findings suggest that hepatoid carcinoma of the ovary is probably derived from carcinomas of surface epithelial origin by a process of neometaplasia or transdifferentiation.- - - - - - - - - - ranking = 0.5keywords = antigen (Clic here for more details about this article) |
3/3. Effect of combination chemotherapy with cisplatin and cyclophosphamide on human immunodeficiency virus type-1 surrogate markers in a patient with advanced epithelial ovarian cancer.This is the first report to evaluate the effects of combination chemotherapy on hiv-1 surrogate markers in an hiv-1-infected patient with an advanced epithelial ovarian cancer. cisplatin combined with cyclophosphamide was well-tolerated, without significant changes in the hiv-1 p24 antigen, neopterin, beta 2-microglobulin, and CD4 values. The patient demonstrated a chemical and clinical response to therapy, without evidence of opportunistic infection or severe neutropenia. During the 6-month period of observation, treatment with cisplatin and cyclophosphamide did not significantly increase the risk of hiv-1 disease progression.- - - - - - - - - - ranking = 0.5keywords = antigen (Clic here for more details about this article) |
