1/48. Malignant Brenner tumors of the ovary and tumor markers: case reports.We investigated the tumor marker for malignant Brenner tumors, which had not been established because of the rarity and variable histological criteria. Representative areas of two cases of malignant brenner tumor were investigated by means of the peroxidase-antiperoxidase method using monoclonal antibody to CA125 and CA72-4 antigen and the streptavidin-biotin immunoperoxidase complex method using monoclonal antibody to SCC antigen. Based on clinical course and immunohistochemical studies, serum CA125 and CA72-4 for Case 1 and SCC and CA72-4 for Case 2 were appropriate tumor markers for the establishment of the extent of tumor burden before treatment and to monitor the response to therapy. The discrepancy of the tumor markers of the two present cases is considered to be a reflection of the difference in the malignant component of these cases. However, serum CA72-4 was an appropriate tumor marker for both malignant Brenner tumors.- - - - - - - - - - ranking = 1keywords = ovary (Clic here for more details about this article) |
2/48. Endodermal sinus tumour of the ovary in pregnancy.We present a case of a 30-year-old pregnant woman in whom an ovarian mass was identified by ultrasonography at 15 weeks' gestation. A markedly elevated maternal serum alphafetoprotein (MSAFP) suggested a diagnosis of endodermal sinus tumour of the ovary. A right salpingo-oophorectomy at 19 weeks' gestation enabled histological confirmation of the diagnosis and suggested a stage 1 tumour. Unfortunately tumour recurrence necessitated further laparotomy and delivery by caesarean section at 32 weeks' gestation. A total abdominal hysterectomy and left salpingo-oophorectomy was undertaken with resection of the splenic flexure and formation of a double-barrelled colostomy after which no gross intraperitoneal tumour remained. Three weeks later a new suprahepatic tumour mass was excised and the colostomy was closed. The patient then received four cycles of combination chemotherapy with cisplatin, etoposide, and bleomycin. Unfortunately she developed a faecal fistula at the site of the colostomy. Germ cell tumours are highly responsive to chemotherapy. Over-zealous surgery particularly involving bowel resection may cause unnecessary morbidity and compromise the outcome.- - - - - - - - - - ranking = 1.25keywords = ovary (Clic here for more details about this article) |
3/48. Liver invasion by recurrent granulosa cell tumour of the ovary: imaging findings.Granulosa cell tumour of the ovary is a rare neoplasm of low malignant potential, late recurrences, local spread and high survival rates. We report the MR imaging appearance of invasion of the liver parenchyma by recurrent granulosa cell tumour of the ovary 15 years after initial diagnosis.- - - - - - - - - - ranking = 1.5keywords = ovary (Clic here for more details about this article) |
4/48. Massive solitary metastasis of hepatocellular carcinoma in the ovary two years after liver transplantation.Case report of a 47-year-old woman with a mass in the lower abdomen, was referred to us by the surgeon, two years after orthotopic liver transplantation for hepatocellular carcinoma (HCC). serum alpha-fetoprotein (AFP), which was elevated at the time of initial diagnosis, was in the normal range. Frozen section examination during exploratory laparotomy showed appearances consistent with metastatic HCC in the ovary. This was confirmed at the final pathological examination. Definitive pathological conclusions were based on the findings of tumor cells arranged in trabecular and papillary aggregates, and the presence of bile-pigment, along with the patients history. This is the sixth case of metastatic HCC in the ovary being described in literature and the first case in which this metastasis was not accompanied by elevated AFP.- - - - - - - - - - ranking = 1.5keywords = ovary (Clic here for more details about this article) |
5/48. Management of recurrent juvenile granulosa cell tumor of the ovary.BACKGROUND: Juvenile granulosa cell tumors of the ovary are a rare form of neoplasm that makes up less than 5% of ovarian tumors in childhood and adolescence. About 90% are diagnosed in stage I with a favorable prognosis. More advanced stages (FIGO stages II--IV) have a poor prognosis. CASE: A patient was initially diagnosed at age 17 with FIGO stage IIIC disease and treated with a right salpingo-oophorectomy, debulking, and staging followed by six cycles of carboplatin and etoposide chemotherapy. Tumor recurrence in the liver and adjacent to the spleen occurred 13 months after completion of primary therapy. Aggressive surgical removal of tumor followed by six cycles of bleomycin and taxol as salvage chemotherapy resulted in 44 months of disease-free survival. On November 27, 2000, she had a cesarean delivery of a 2335-g normal male due to a breech presentation. Exploration revealed no evidence of tumor. CONCLUSION: This is the second case report of a patient with advanced juvenile granulosa cell tumor to become pregnant after apparently successful chemotherapy. These results are encouraging, but the best treatment for extensive and recurrent disease has yet to be determined.- - - - - - - - - - ranking = 1.25keywords = ovary (Clic here for more details about this article) |
6/48. Teratoid carcinosarcoma of the ovary with prominent neuroectodermal differentiation.We present what we believe to be only the second report of ovarian teratoid carcinosarcoma. The patient, a 59-year-old woman, was admitted to hospital complaining of a pelvic mass and of abdominal fullness. Advanced ovarian cancer was diagnosed, and a tumorectomy was done. The tumor occupied the pelvis, and metastasis was found in the liver and spleen. The solid tumor was composed of chondrosarcoma, squamous cell carcinoma, adenocarcinoma and malignant neuroectodermal components, which contained ganglioneuroblastoma-like and medulloepithelioma-like areas. Immunohistochemically, the neuroectodermal cells were positive for both neural and epithelial markers. This ovarian tumor consisted of frankly malignant components, with prominent neuroectodermal elements mixed with epithelial and mesenchymal elements in an organoid fashion; a quite rare tumor.- - - - - - - - - - ranking = 1keywords = ovary (Clic here for more details about this article) |
7/48. 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 = ovary (Clic here for more details about this article) |
8/48. desmoplastic small round cell tumor: report of a case presenting as a primary ovarian neoplasm.BACKGROUND: desmoplastic small round cell tumor (DSRCT) is an intra-abdominal malignancy that typically has extensive peritoneal spread at the time of diagnosis. We report a case of DSRCT with involvement of the ovary and omentum as well as an elevated CA-125 level at presentation. CASE: A 23-year-old female presented to another institution with a pelvic mass and a CA-125 level of 140 U/ml. During tumor reductive surgery the right ovary, omentum, and liver were found to be involved. Initial histologic examination favored an undifferentiated small cell carcinoma of the ovary. The patient received two cycles of Taxol and cisplatin chemotherapy and was referred to the University of texas M. D. Anderson Cancer Center. Upon review of the pathology material at the time of the referral, a diagnosis of DSRCT was made. Despite two additional cycles of chemotherapy, the tumor progressed, and the patient returned home. CONCLUSION: DSRCT may mimic an ovarian primary tumor by presenting with involvement of the ovary and an elevated CA-125 level, and should be included in the differential diagnosis of ovarian neoplasms in young patients.- - - - - - - - - - ranking = 1keywords = ovary (Clic here for more details about this article) |
9/48. carcinoembryonic antigen: clinical and historical aspects.To further define and determine the usefulness of CEA, 1100 CEA determinations have been made over the past two years at The ohio State University hospitals on patients with a variety of malignant and nonmalignant conditions. Correlation of CEA titers with history and clinical course has yielded interesting results not only in cancers of entodermally derived tissues, for which CEA has become an established adjunct in management, but also in certain other neoplasms and inflammatory states. The current total of 225 preoperative CEA determinations in colorectal carcinomas shows an 81% incidence of elevation, with postoperative titers remaining elevated in patients having only palliative surgery but falling to the negative zone after curative procedures. An excellent correlation exists between CEA levels and grade of tumor (more poorly differentiated tumors showing lower titers). Left-side colon lesions show significantly higher titers than right-side lesions. CEA values have been shown to be elevated in 90% of pancreatic carcinomas studied, in 60% of metastatic breast cancers, and in 35% of other tumors (ovary, head and neck, bladder, kidney, and prostate cancers). CEA levels in 35 ulcerative colitis patients show elevation during exacerbations (51%). During remissions titers fall toward normal, although in 31% still remaining greater than 2.5 ng/ml. In the six colectomies performed, CEA levels all fell into the negative zone postoperatively. Forty percent of adenomatous polyps showed elevated CEA titers (range 2.5-10.0) that dropped following polypectomy to the negative zone. Preoperative and postoperative CEA determinations are important in assessing the effectiveness of surgery. Serial CEA determinations are important in the follow-up period and in evaluation of the other modes of therapy (e.g., chemotherapy). These determinations of tumor antigenicity give the physician added prognostic insight into the behavior of the tumor growth. Rectal examination with guaiac determinations, sigmoidoscopy, cytology, barium enema, and a good clinical evaluation remain the primary tools for detecting colorectal disease. However, in the high-risk patient suspicious of developing cancer, CEA determinations as well as colonoscopy are now being used increasingly and provide additional highly valuable tools in the physician's armamentarium.- - - - - - - - - - ranking = 0.25keywords = ovary (Clic here for more details about this article) |
10/48. Borderline serous cystadenocarcinoma with coexistent angiosarcoma: an unusual form of ovarian carcinosarcoma.A 45-year-old woman presented with a short history of abdominal distension and features of intestinal obstruction. Computed tomography examination of the abdomen revealed a solid and cystic mass in the region of the left ovary, but spread within the abdomen was also noted. The ovarian tumor was removed, and an omentectomy was also performed. Microscopic examination of the ovarian tumor and metastases within the omentum showed a carcinosarcoma composed of borderline serous papillary cystadenocarcinoma and angiosarcoma. The angiosarcomatous component was the dominant tumor within the omentum. This case documents an unusual combination of epithelial and sarcomatous elements in an ovarian carcinosarcoma. The tumor behaved aggressively because of the angiosarcomatous component, and since the patient was assessed as having stage IV disease, no further treatment was offered.- - - - - - - - - - ranking = 0.25keywords = ovary (Clic here for more details about this article) |
