BACKGROUND: The way to select patients who will benefit from surgical resection of pulmonary metastases of colorectal carcinoma (CRC) remains unclear. METHODS: We analyze overall survival and potential prognostic factors in 101 pulmonary resections of CRC metastases in 79 patients, focusing on cases with repeated pulmonary resection or with hepatic metastasectomy. RESULTS: Number of pathological pulmonary metastases was higher than that of preoperatively suspected pulmonary nodules in 18% of the resections...

Endometriosis is a frequent benign gynecological disease; nonetheless, it can demonstrate some aspects that resemble malignant disease. Malignant transformation of endometriosis occurs mainly in the ovary. A rare case of transition between typical endometriosis and clear cell carcinoma with immunohistochemical study is presented. The patient, a 30-year-old Caucasian woman (para 0), was diagnosed with endometriosis ten years before. Six months later she developed a left cystic ovarian tumor (58 cm3) that persisted after two ultrasounds in a four-month period...

BACKGROUND: Craniopharyngioma is a rare, benign epithelial brain tumor of the suprasellar region with a high rate of recurrence. Clinical and histopathological features that might be predictors of recurrence/regrowth have not been clearly delineated. METHODS: We compared recurrence/regrowth of the tumors with the clinico-pathological characteristics, vascular density, cell proliferation index, and immunohistochemical profile (cytokeratins, epithelial membrane antigen [EMA], carcinoembrionary antigen [CEA], and laminin) of 47 patients with craniopharyngioma followed for more than 5 years...

INTRODUCTION: von Willebrand factor (vWf) is thought to mediate binding of tumour cells to platelets and to favour their systemic spreading capacity. Platelets involved in tumour angiogenesis are capable of releasing vascular endothelial growth factor (VEGF). Hence, levels of vWf and VEGF may correlate with cancer stage. The objectives are determine the impact of surgery and chemotherapy on vWf and VEGF in colorectal cancer (CRC) patients. MATERIAL AND METHODS: Twenty healthy volunteers (group 1), 14 patients with locally advanced CRC (group 2) and 12 patients with metastatic CRC (group 3) were enrolled...

BACKGROUND AND OBJECTIVE: We have carried out a comparative prediction analysis in sporadic colorectal carcinoma of plasmatic lipids and currently tumor markers used in this neoplasia (carcinoembrionary antigen - CEA, CA 19.9 and sialic acid -SA). PATIENTS AND METHODS: Transversal hospital-based case-control study. Sample was composed by 53 sporadic colorectal neoplasia patients just before surgery and 40 non matched controls. A 90 per cent of cases were at Dukes A and B stages...

Occupational and environmental asbestos exposure continues to represent a public health problem, despite increasingly restrictive laws adopted by most industrialized countries. Peritoneal mesothelioma is a rare and aggressive asbestos-related malignancy. We present the case of a 65-year-old man who developed recurrent ascites after having been exposed to asbestos in the building industry for > 40 years. Liver function and histology were normal. Abdominal computed tomography initially excluded the presence of expansive processes, and no abnormal cells were found in the ascitic fluid...

Dipeptidyl peptidase IV(DPPIV) or CD26 is a widely expressed ectopeptidase with functions in immune response such as the activation of T lymphocytes. It is expressed in the colon mucosal epithelium only when this becomes malignant. The aim of our study is to ascertain the soluble DPPIV/CD26 levels in the serum of patients with colorectal carcinoma, compared with the levels in healthy individuals. From an accrual of 70 healthy individuals and 99 patients diagnosed with colorectal adenocarcinoma, the levels of soluble DPPIV/CD26 were defined by colored enzymatic spectrophotometric response on the Gly-Pro-Paranitroaniline substrate...

In Peru, the Colorectal Cancer affects people of both sexes, making it necessary to know the clinical characteristics of this disease, in order to improve its diagnosis. With this purpose it was set a retrospective and descriptive study at E. Rebaglitati Martins Hospital. We included those patients that were attended between 1995 and 1999 and that had a pathologic diagnostic of colorectal cancer. The rectal tumor was the most frequent in males (40.9%) and females (31.3%). The kind of symptoms was related with the tumor localization, in rectum, it predominates hematochezia (29...

UNLABELLED: A series of 7 cases of chromophobe cell carcinoma with clinicopathological correlation is studied. The immunohistochemistry analysis was carried out evaluating in all cases: low and high cytoqueratines (AE1, AE3), membrane epithelial antigen (EMA), vimentin, carcinoembrionary antigen (CEA), proliferative cell nuclear antigen (PCNA) and the oncoproteins p53 and focal c-erbB2. In all cases a diffuse positivity for EMA, AE3 and focal for AE1 was observed, while vimentin and CEA were negative...

The bronchoalveolar lavage (BAL) is considered a basic technique as a diagnostic aid in Pneumology. However, one of the main problems faced by the clinician is the lack of standardization of the technique. This has been resolved through the drafting of international standards. The other problem is the lack of what might be called a "reference" BAL. In order to establish a reference BAL, we analyzed 203 BAL divided in two groups: a control group and a pathologic group, make up by extrinsic asthma, intrinsic asthma, pulmonary infections, diffuse interstitial pneumopathies, bronchopulmonary tumors and chronic bronchitis...

The carcino-embrionary antigen was estimated in 26 patients without malignant diseases (15 with inguinal hernia and 11 with urinary lithiasis--all of them before surgery), and in 47 patients with urothelial tumors. The direct radioimmune technique was used (a commercial kit from France /CEA IRE SORIN/) applied to isolated samples of sterile urine obtained at 12 hours. It was noted that:--patients without urologic disturbances had values under 1.5 micrograms in 12 hours in 93.4% of the cases;--in 44% of patients with non-malignant urological diseases (urinary lithiasis) the antigen values ranged between 1...
