A study of 207 consecutive white patients older than 18 years of age with nonfamilial nodular and superficial spreading melanoma and 295 controls was conducted in southeast France. Controls were recruited in a public health center. They were matched for sex and age to the overall population older than 18 years of age according to the last census.(More)
A prospective survey was conducted to assess the role of patients in the melanoma prognosis. Consecutive patients with primary melanoma were interviewed and examined using a comprehensive questionnaire including a psychological instrument. Main outcome measures were the delay before medical intervention and the tumor thickness. Of 590 melanomas, 70.8% were(More)
Excessive sun exposure in the first 15 years of life has been shown to be a determinant risk factor for melanoma. This study was conducted on a randomly selected sample of 200 adolescents (13-14 years old) and 150 children (3 years old) in Marseille (South of France). Children and adolescents were examined and interviewed (mothers answered for young(More)
OBJECTIVE The purpose of this study was to determine the prognostic value of the expression of protein p53, EGF receptors (EGR-R), cell proliferation antigen (Ki67) and DNA analysis by flow cytometry on per-endoscopic biopsies as well as the ability of these factors to predict response to concomitant chemoradiation in patients with squamous cell oesophageal(More)
A continuous series of 125 patients hospitalized between 1973 and 1987 with pleural malignant mesothelioma were the subjects of this stepwise analysis. A diagnostic thoracoscopy was carried out in every patient and the histopathological diagnosis confirmed by the French Mesothelioma Panel of Pathologists. The main characteristics of the patients were: mean(More)
MSH2 and MLH1 are proteins involved in DNA reparation. They are mutated in some forms of colon cancer, i.e. hereditary non-polyposis carcinomas and a subset of sporadic carcinomas. We have studied the expression of MSH2 and MLH1 in a retrospective series of 225 colorectal carcinomas by immunohistochemistry. The results were compared to molecular tests of(More)
Thrombin-activatable fibrinolysis inhibitor (TAFI) is a recently described fibrinolysis inhibitor that circulates in plasma as a procarboxypeptidase and is converted into an active form during coagulation. The physiological relevance of TAFI is not known, but it might be involved in pathways regulating fibrin deposition. Our aim was to determine the(More)
BACKGROUND Thoracoscopy appears to be essential in identifying tumors at the beginning of pleural disease. METHODS Between 1973 and 1990, diagnostic thoracoscopy was carried out in a prospective series of 188 patients with malignant pleural mesothelioma (MPM). Biopsy samples were obtained in all cases, and diagnosis was confirmed by the French panel of(More)
Gastrin stimulates the growth of some human colon adenocarcinomas grown in vitro or as xenografts in nude mice. To evaluate the possibility of elevated plasma gastrin levels in patients with adenomatous polyps or colorectal cancer, we carried out a radioimmunoassay in subjects fasting overnight and undergoing colonoscopy. The study included 190 patients who(More)
In this study, we investigated endoscopic biopsy material consisting of 76 esophageal squamous cell carcinomas after immunostaining with three p53 monoclonal antibodies (PAb 1801, PAb 240, and DO-7). p53 protein was detected in 51.3% of the tumours. The protein was not expressed in the normal mucosa. Statistical analysis of follow-up data on 54 patients(More)
