BACKGROUND We have conducted a population-based study of pleural mesothelioma patients with occupational histories and measured asbestos lung burdens in occupationally exposed workers and in the general population. The relationship between lung burden and risk, particularly at environmental exposure levels, will enable future mesothelioma rates in people born after 1965 who never installed asbe...

Reactive oxygen species (ROS) can promote or inhibit tumorigenesis. In mesothelioma, asbestos exposure to serous membranes induces ROS through iron content and chronic inflammation, and ROS promote cell survival signaling in mesothelioma. Moreover, a current chemotherapy regimen for mesothelioma consisting of a platinum and antifolate agent combination also induce ROS. Mesothelioma is notorious...

Proliferation and apoptotic indices of tumour cells may have important prognostic significance. Manganese superoxide dismutase (MnSOD), an important anti-oxidant enzyme, has been shown to decrease proliferation of malignant cells transfected with the MnSOD gene. The aim of the present study was to investigate the indices of cell proliferation and apoptosis and their prognostic significance in h...

Mesothelioma is the most common malignant primary tumor of the pleura and usually associated with inhalation of asbestos fibers. In contrast, peritoneal mesothelioma is a rare entity whose pathomechanism is not yet fully understood. The coexistence of pleural mesothelioma with secondary involvement of the abdominal cavity has not been addressed in the literature. In this case report, we describ...

BACKGROUND Malignant mesothelioma is a neoplasm of bad prognosis, it is linked with asbestos contact, but there are cases without this antecedent. OBJECTIVE To investigate the relationship of asbestos exposition and other factors with malignant mesothelioma. METHODS Retrospective analysis of histologic confirmed cases of malignant mesothelioma, neoplasic familiar history, tobacco smoking, e...

Because malignant mesothelioma is commonly seen as a diffuse neoplasm, a localized tumor is an extremely rare form of presentation. Only 45 cases have been reported, and little is known about their behavior. We report a new case of localized malignant mesothelioma with the microscopic appearance of diffuse malignant mesothelioma, but without any evidence of diffuse spread. A 54-year-old man, a ...

Malignant mesothelioma is an aggressive and therapy-resistant neoplasm arising from mesothelial cells. Evidence suggests that the major pathology associated with asbestos-induced mesothelioma is local iron overload. In the present study, we induced iron-induced mesothelioma in rats based on previous reports. Ten Wistar rats were given ferric saccharate and nitrilotriacetate i.p. for 5 days a we...

PURPOSE OF THE STUDY To describe the ophthalmic and pathological features of a conjunctival tumour in a 76-year-old male with terminal pleural mesothelioma who developed a rapidly growing mass on the bulbar conjunctiva. PROCEDURES The patient presented with a rapidly growing, pink nodule on the right nasal bulbar conjunctiva. His past medical history included biopsy-confirmed pleural malignan...

Mesothelioma infrequently causes pericardial constriction and rarely symptomatic pericardial tamponade. Most commonly, a primary pleural malignancy will extend locally, but primary involvement of pericardium is also well-recognized. However, pericardial fibrosis in conjunction with pleural mesothelioma has not been described before in the literature. We report a case of pleural mesothelioma wit...

Malignant mesothelioma predominantly arises from the serosal surfaces of the pleural or peritoneal cavity. There is currently no effective standard treatment for mesothelioma and the prognosis for patients is poor; the majority of patients with malignant mesothelioma succumb between 12 and 17 months following diagnosis. The association of all forms of malignant mesothelioma with asbestos exposu...
