1/115. Cirrhotic ascites, ovarian carcinoma, and CA-125.We describe two postmenopausal women with ascites and elevated CA-125 level, a serologic marker used to detect ovarian cancer. Both patients had unrecognized liver disease but underwent surgical exploration for suspected ovarian disease, which subsequently revealed benign pelvic organs. Elevated serum CA-125 levels have been reported in many patients with ascites due to liver disease and cirrhosis. Thus, the presence of both ascites and an elevated CA-125 level mandates a thorough elevation for liver disease as well as for a possibility of ovarian carcinoma. These cases outline the common finding and provide insight into the management of patients with ascites and elevated CA-125 values.- - - - - - - - - - ranking = 1keywords = cancer (Clic here for more details about this article) |
2/115. Markedly elevated CA125 in hepatic cirrhosis: two case illustrations and review of the literature.CA125 is the most widely used tumor marker presently available for use in patients with epithelial ovarian cancer. Although elevated in a high percentage of patients with ovarian cancer, serum CA125 levels have also been detected in patients with numerous benign and malignant nongynecologic disorders, including various diseases of the liver. Despite this well-publicized fact, it has become apparent that the association between CA125 elevation, particularly the degree of elevation, and liver disease may not be as widely recognized as one would suspect. When marked CA125 elevations occur, diagnostic confusion is common. We describe two cases illustrative of this point. Both cases involve middle-aged women who presented with massive ascites and due to markedly elevated serum CA125 levels underwent exploratory laparotomy with hysterectomy and/or bilateral salpingo-oopherectomy before their referral to our center. Because preservation of a woman's reproductive organs is a significant concern, it is imperative that both primary care physicians and specialists are aware of such associations and the proper use of tumor markers.- - - - - - - - - - ranking = 2keywords = cancer (Clic here for more details about this article) |
3/115. Cytology of ascitic fluid in a patient with granulocytic sarcoma (extramedullary myeloid tumor). A case report.BACKGROUND: Granulocytic sarcoma (GS) is the rare extramedullary manifestation of acute myeloid leukemia that may precede or be concurrent with leukemic infiltration of bone marrow or herald blastic transformation of a chronic myeloproliferative disorder. It has been found in most body sites and shows no age or sex predilection, necessitating its inclusion in the differential diagnosis of undifferentiated neoplasms. CASE: A 36-year-old female presented with a three-year history of abdominal pain, jaundice and fluctuating abdominal girth. Cytology of the ascitic fluid revealed myeloid cells of eosinophilic lineage at all stages of differentiation, with many undifferentiated cells. Immunohistochemical studies on a cell block confirmed the diagnosis of granulocytic sarcoma, which excluded the differential diagnoses of Hodgkin's disease, non-Hodgkin's lymphoma and Langerhans histiocytosis. CONCLUSION: Granulocytic sarcoma may present as a serous effusion and can be diagnosed on a cytologic specimen.- - - - - - - - - - ranking = 0.016814420559471keywords = neoplasm (Clic here for more details about this article) |
4/115. Massive pleural effusion and ascites resulting from esophagectomy with extensive lymphadenectomy for cancer of the abdominal esophagus.chylothorax is an uncommon but well recognized complication of esophagectomy. We present the case of a 57 year-old man with squamous cell carcinoma of the abdominal esophagus who underwent subtotal esophagectomy by right thoracotomy. Post-operatively, the volume of pleural effusion from the right chest was increased (1600-2000 ml/day). The effusion was straw colored, not changing to milky after meals. The characteristics and composition of the pleural fluid were similar to those of chyle. We therefore treated this patient using methods for treatment of chylothorax, conservatively, by administration of OK-432 and minocycline/hydrochloride into the pleural cavity from the chest tube with success. We discuss the pathophysiology of this unusual condition and its treatment.- - - - - - - - - - ranking = 4keywords = cancer (Clic here for more details about this article) |
5/115. Renal fibrohistiocytic sarcoma. Three cases and a review of the literature.The purpose of this paper is to report three unpublished cases of so-called "renal malignant fibrous histiocytoma" which should be more appropriately called "renal fibrohistiocytic sarcoma", and to review and analyze the data concerning 41 cases collected from the literature and our three new cases, making a total of 44 cases. Our third case is very interesting; in addition to the fact that this condition is rare, this particular patient also had concomitant nonmalignant ascites and compression of the descending colon, both conditions being rarely associated with renal cancer. The average age of the patients was 58 years; in 66% of the cases the tumor involved the left kidney; 57% of the patients were males; the average tumor size was 12 cm; nephrectomy was performed in 93% of the cases; the average survival was 16 months. In none of the cases was a preoperative diagnosis correctly made. It is concluded that a triad of symptoms and signs (renal pain, weight loss, and large tumor size) as well as a triad of imaging characteristics (areas of low density on the CT scan, hypoechoic areas on ultrasound, and hypovascularity on angiography) may hold the promise of a preoperative diagnosis. It is suggested that the tumor arises from the system of Gerota's fascia-renal capsule.- - - - - - - - - - ranking = 1.0909997315044keywords = cancer, kidney (Clic here for more details about this article) |
6/115. Bilateral renal agenesis and fetal ascites in association with partial trisomy 13 and partial trisomy 16 due to a 3:1 segregation of maternal reciprocal translocation t(13;16)(q12.3; p13.2).A female fetus with bilateral renal agenesis and fetal ascites was found to have partial trisomy 13 (pter-q12.3) and partial trisomy 16 (p13.2-pter), 47,XX, der(13)t(13;16)(q12.3; p13.2)mat. The chromosomal aberration was due to a 3:1 segregation with tertiary trisomy transmitted from a maternal reciprocal translocation 13;16. Prenatal ultrasound of a 29-year-old, gravida 2, para 0 woman at 22 gestational weeks showed fetal ascites, severe oligohydramnios and non-visualization of fetal urinary bladder and kidneys. The pregnancy was terminated. At delivery, the proband displayed dysmorphic features of hypertelorism, a prominent glabella, epicanthic fold, a stubby nose with a depressed nasal bridge, anteverted nares, thin lips, micrognathia, low-set ears, a short neck and a distended abdomen. Necropsy confirmed bilateral renal agenesis and ascites. A cytogenetic study performed on fibroblasts obtained from the proband's skin revealed an extra supernumerary chromosome. The mother was later found to have a reciprocal translocation. fluorescence in situ hybridization for a submicroscopic deletion in chromosome 22q11 in the proband was negative. The parents had no urological anomalies. Our observation further extends the clinical spectrum associated with proximal trisomy 13q and distal trisomy 16p. We suggest prenatal cytogenetic analysis in fetuses with urological anomalies, including renal agenesis, to uncover underlying genetic disorders.- - - - - - - - - - ranking = 0.090999731504425keywords = kidney (Clic here for more details about this article) |
7/115. Pancreatic cancer associated ascites-derived CTL recognize a nine-amino-acid peptide GP2 derived from HER2/neu.BACKGROUND: The proto-oncogene HER2/neu encodes a 185 kDa transmembrane protein with extensive homology to the epidermal growth factor receptor. It is overexpressed in several human cancers of epithelial origin, such as pancreatic cancer. Previously, we demonstrated that CTL derived from breast, ovarian, and non-small cell lung cancer recognized a peptide derived from HER2/neu. The aim of this study was to evaluate whether this HLA-A2-binding peptide is a TAA in pancreatic cancer and if pancreatic cancer associated t-lymphocytes (TAL) are useful to generate tumor- and peptide-specific CTL. MATERIALS AND methods: TAL from malignant ascites of a HLA-A2 pancreatic cancer patient whose tumor overexpressed HER2/neu were stimulated on solid-phase anti-CD3 and cultured in low-dose IL-2. Using repetitive autologous tumor cell stimulation, CTL were generated. RESULTS: CTL recognized autologous and allogeneic HER2/neu tumor cells in an HLA-A2 restricted fashion significantly. Furthermore, all CTL recognized p654-662 (GP2) derived from HER2/neu, but not the control peptide. CONCLUSIONS: These results demonstrate that this HER2/neu derived peptide is a TAA in pancreatic carcinoma. The identification of the HER2/neu derived peptide GP2 as a TAA in pancreatic cancer provides an opportunity for the design of novel immunotherapy and vaccine strategies. The possibility of generating peptide-specific CTL from malignant ascites enables future studies to identify more antigens in this disease.- - - - - - - - - - ranking = 11keywords = cancer (Clic here for more details about this article) |
8/115. Comparative microsatellite analysis in discerning origin of disseminated tumor: the case of a patient with malignant ascites and a history of multiple tumors.The origin of metastatic carcinoma is now always easily resolved on the basis of conventional dinical and pathological parameters, particularly in patients with more than 1 primary tumor. When 1 of the tumors is a renal cell carcinoma, the clinical picture is further confounded by the tendency of these tumors to be locally silent, to metastasize to unusual sites, and to disseminate long after removal of the primary tumor. We compared tumors for loss (ie, deletion) of loci on chromosomal arms 3p, 5q, 11q, and 18q in a patient with a malignant ascites fluid, a remote history of renal and colonic neoplasms, and a strong clinical suspicion of disseminated gastrointestinal adenocarcinoma. dna from microdissected tumors and normal tissues was subjected to polymerase chain reaction-based microsatellite analysis. Even though the clinical picture suggested a gastrointestinal origin, comparison of genetic alterations clearly showed that the malignant ascites represented recurrence of the renal cell carcinoma. The malignant ascites and the primary renal cell carcinoma showed identical patterns of allelic loss at all loci tested. In contrast, the malignant ascites and colonic adenoma showed discordant patterns of allelic loss. Comparative microsatellite analysis provides a rapid genetic approach for discerning the origin of metastatic tumor spread. This may be a useful diagnostic adjunct when tumor origin is not clear on clinical or morphological grounds. In some instances, it may even provide a reasonable alternative to an extensive and costly conventional work-up.- - - - - - - - - - ranking = 0.016814420559471keywords = neoplasm (Clic here for more details about this article) |
9/115. Spontaneous splenic rupture due to subcutaneous heparin therapy.We report a case of spontaneous splenic rupture in a 59-year-old woman who was receiving 15,000 units of heparin subcutaneously (s.c. ) twice a day for deep venous thrombosis (DVT) prophylaxis. Her past medical history included multiple DVT, pulmonary emboli, and ovarian cancer stage III-C with known ascites. The diagnosis of splenic rupture was initially missed because of the ascites. This case illustrates both a previously undescribed complication of s.c. heparin therapy and a failure of ultrasound diagnosis. We emphasize the unique presentation, difficulty in diagnosis, and need for early surgical involvement to ensure the most favorable outcome.- - - - - - - - - - ranking = 1keywords = cancer (Clic here for more details about this article) |
10/115. Laparoscopic diagnosis and management of malignant ascites.Malignancy is the second most common cause of ascites. Tissue diagnosis is often difficult because the cytology of ascitic fluid is positive in only 57% of cases. Peritoneovenous shunting is often used as palliation in such patients and has proven superior to nonoperative management for some patients. We present three cases of malignant ascites with negative cytologies managed by using laparoscopic biopsies to confirm intraperitoneal cancer and assist in the placement of a peritoneovenous shunt. Results suggest that exploratory laparoscopy and shunt placement is a valuable procedure in these patients with a limited life expectancy and is preferable to open laparotomy.- - - - - - - - - - ranking = 1keywords = cancer (Clic here for more details about this article) |
