North Carolina Textile Workers Exposed to Carcinogen

The intent of the study was to describe mortality among workers and examine possible relationships between exposure and mortality rates.

Mortality in the Vital status of workers employed for at least 1 day between 1 January 1950 and 31 December 1973 in four North Carolina plants was compared and tracked.

Of 5770 workers, 2583 deaths werefrom all causes; 277 from lung cancer. Mortality from all causes, (all cancers and lung cancer was significant higher than expected).

The risk of lung cancer and asbestosis increased with cumulative fibre exposure. Details of the study are available from the source listed below.

Maine Asbestos Problem

Posted: under Medical, Press Releases.

Maine now has the highest death rate from mesothelioma in United States according to the National Institute for Occupational Health and Safety (NIOSH).

The U.S. Centers for Disease Control (CDC) agency NIOSH indicates twenty seven asbestos-related deaths per million. As that turns out to be about 80 deaths a year, it may indicate a risk factor especially for high risk groups.

Biography

Dr. Sugarbaker is board certified in Thoracic Surgery and Surgery. He attended Wheaton College and Cornell University Medical School. He completed his Surgery residency at Brigham and Women’s Hospital and Cardiothoracic training at the Toronto General Hospital as Chief Resident in Thoracic Surgery and Chief Resident in Cardiac Surgery. His specific interests are in general thoracic surgery, minimally invasive surgery, lung volume reduction surgery, esophageal cancer, mesothelioma, non-small cell lung cancer, and video-assisted thoracic surgery(VATS).

Dr. Sugarbaker has been actively involved in the development of several programs. These include The Division of Thoracic Surgery 1988-present, the Brigham Lung Transplant Program, The Thoracic Oncology Program at the DFCI/BWH 1995-present, Surgical Services at the DFCI 1996-present, the Lung Volume Reduction Program at BWH 1996-present. In addition he has been active in the development of new minimally invasive surgical procedures and actively involved in the areas of therapy of thoracic malignancy.

Malignant pleural mesothelioma has been a central focus of Dr. Sugarbaker’s clinical and laboratory research. A trimodality therapeutic approach based on extrapleural pneumonectomy and adjuvant chemotherapy and radiation was developed and examined in a consecutive series of patients. Analysis of this series has revealed improved overall survival with acceptable morbidity and operative mortality, and has elucidated new prognostic variables in this disease. These include cell type, nodal status and resectablity, which have formed the foundation of a new staging system currently in use, which was presented to the American Surgical Association in 1996.

Laboratory investigation in mesothelioma has entailed the banking of frozen samples of more than 100 mesotheliomas that are currently the focus of research examining molecular markers in this disease. One important project seeks a definitive answer as to the potential role of Simian Virus 40 exposure (e.g. via contaminated polio vaccine) in mesothelioma through collaborative involvement with the NIH SV-40 working group.

As Chair of the Surgery Committee of the Cancer and Leukemia Group B (CALGB), it has been possible for Dr. Sugarbaker to play a leadership role in developing the clinical investigation of the role of surgery in cancer therapy trials, with the support of NCI U10 funding. This effort has supported the clinical investigation of new therapies in thoracic, GI and breast malignancies. These prospective clinical investigations have led to further NCI U10 support to examine the efficacy of new innovative minimally invasive thoracic surgery techniques in the staging and treatment of thoracic malignancy.

Concurrent laboratory work has focused on prognostic factors in stage I non-small cell lung cancer. Although surgery alone is standard therapy in this group of patients, 30-40% of them will succumb to recurrent disease. Identification of molecular and pathologic prognostic markers indicating metastatic potential in resected stage I tumors will facilitate selection of patients for adjuvant therapy. The evaluation of markers in our laboratory has led to the publication of a molecular substaging system for stage I non-small cell lung cancer. The prognostic significance of markers currently under study utilizes specimens from our respiratory tissue bank.

The establishment of the respiratory tissue bank in 1991 has led to the development of new methodologies for tissue processing and storage. This activity has led to extremely fruitful collaborative research projects. Prominent among these is “A gene expression approach to Adenocarcinoma classification”, a funded response to the NCI Director’s Challenge involving investigators at the Whitehead Institute, DFCI, MGH and BWH. Others have focused on the role of cell cycle regulatory pathways (Rb, cyclin D1, p16), matrix metalloproteinases (stromelysin-3), adhesion/motility proteins (paxillin, gelsolin), retinoid receptors and macrophage stimulating protein in the pathogenesis and metastasis of lung cancer. The bank has also supported large-scale gene discovery and expression profiling work in malignant pleural mesothelioma. “Evaluation of assays for detection of Simian Virus 40 DNA in Mesotheliomas”, a multicenter study by the International SV40 Working Group organized by the Viral Epidemiology Branch of the NCI, utilized specimens from the bank in a careful investigation of this sensitive public health issue.

Recently, the scope of the bank has been expanded. The BWH Tissue and Blood Repository now serves a broader role as an institutional core facility for specimen procurement and distribution in a wide array of malignancies as well as benign and neo-plastic tissues, blood, cells and nucleic acids. Dr. Sugarbaker serves as co-director and operations chair.

Dr Sugarbaker is Chief of Thoracic Surgery at Brigham and Women’s Hospital and the Richard E. Wilson Professor of Surgical Oncology at Harvard Medical School.

Early detection of malignant pleural mesothelioma through measurement of soluble mesothelin-related protein and positron emission tomography.

Posted: under Medical, Pubmed.

Things are looking much improved for early detection…

Article Abstract: A 51-year-old man with no known history of asbestos exposure presented with hydropneumothorax. Soluble mesothelin-related protein testing and combined positron emission tomography and computed tomography were used to diagnose malignant pleural mesothelioma. One year after radical surgery and radiotherapy, there was no clinical recurrence.

Details about Asbestos You Probably Know

Posted: under Medical.

The National Cancer Institute says asbestos is a known carcinogen that can increase the risk of lung cancer and mesothelioma, a relatively rare cancer of the thin membranes that line the chest and abdomen.

It can also increase the risk of asbestosis, a chronic lung condition that can cause shortness of breath, coughing and permanent lung damage.

Asbestos is a health hazard to construction workers who may be exposed to it on a regular basis, which is why the IEPA requires firms discovering asbestos to report it, halt demolition and hire a licensed asbestos removal firm.

Chemoembolization Used in Mesothelioma Treatment

Posted: under Medical.
Tags:

Chemoembolization is a treatment being developed in Germany to treat tumors. Dr. Thomas Vogl, a doctor in Frankfurt, is using chemoembolization to treat mesothelioma, and anecdotally, the treatment has shown some promise.

Chemoembolization is a combination of local delivery of chemotherapy and a procedure called embolization to treat cancer. In the process, first, anti-cancer drugs are injected directly into the tumor. Then, an embolic agent is placed inside the blood vessels trapping the chemotherapy in the tumor.

A Virus Targeting Mesothelioma?

Posted: under Medical.

Masonic Cancer Center members Robert Kratzke, M.D., and Faris Farassati, Ph.D., Pharm.D., are conducting key research on the asbestos-related cancer mesothelioma with grants from the Mesothelioma Applied Research Foundation (Meso Foundation).

Farassati, assistant professor with the University’s Medical School and member of the Cancer Center’s Genetic Mechanisms of Cancer Research Program, received a $100,000 grant in 2007 from the Meso Foundation. He is using the funds to devise an innovative mechanism to directly attack mesothelin, the protein that is expressed in high levels by mesothelioma cells. He is developing a virus which can selectively target and obliterate mesothelin and thereby destroy the cancer cells.
