Among the many wonderful speakers at the 2009 International Symposium on Malignant Mesothelioma, presented by the Mesothelioma Applied Research Foundation in June, was Dr. Jill Ohar of Wake Forest University. She has been researching mesothelioma and other asbestos diseases for more than 20 years, and currently is heading a study to determine if there could be a genetic predisposition between asbestos exposure and the development of mesothelioma.

Dr. Ohar told conference attendees that her goal is to try to discover why some people may be exposed to asbestos and never develop any type of asbestos disease, while others may develop asbestosis, lung cancer or mesothelioma. She had already collected blood samples and DNA from 6,000 people exposed to asbestos for an epidemiologic study. Of that number, she said, 250 people developed mesothelioma.

“What is different in those people?” she wondered.

The next phase of the study is a genome study involving the 250 patients who did develop mesothelioma. In addition, Dr. Ohar is seeking additional participants.

A news release on Oct. 5 announced that FirstHealth of the Carolinas, a comprehensive health care network serving 15 counties in the mid-Carolinas, will partner with the Wake Forest School of Medicine to encourage participation in the study, which is investigating the development and progression of asbestos-related lung diseases and cancers. The FirstHealth Clinical Trials Department will work on this project.

Dr. Ohar is the study’s principal investigator. In the news release she says, “Families have been devastated by this disease, but what is surprising is that despite the strong association of asbestos exposure to mesothelioma, only a small number of people exposed to asbestos actually develop mesothelioma. Over years of research, we have determined that there is a strong tendency for mesothelioma to run in families and it tends to be associated with a family history of cancer, which suggests a genetic susceptibility.”

The mesothelioma study requires the collection of one ounce of blood from the participant and the completion of a tw0-page survey, both to be conducted at FirstHealth Moore Regional Hospital’s Chest Center of the Carolinas.

The study will examine associated environmental factors and genetic markers of people diagnosed with mesothelioma, basically identifying how frequently encountered environmental pollutants affect the body and determining the genetic factors that make some families more susceptible than others to mesothelioma and other forms of cancer.

If you or a a friend or family member has been diagnosed with mesothelioma and are interested in participating in this study or have questions, please call FirstHealth Clinical Trials at 910-715-2200 or Dr. Jill Ohar at 866-487-2344 or 336-716-8426.

Asbestos is still not completely banned in the United States. It can still be found in a great number of products. WHY?

Asbestos industry documents from as early as 1924 indicate that manufacturers knew there was a danger to workers who inhaled asbestos fibers.

Then in 1953, Dr. Irving Selikoff, a pulmonary specialist, began studying the link between asbestos exposure and lung disease. He noted a much higher percentage of lung disease among workers who inhaled asbestos fibers. Selikoff’s groundbreaking findings about of the occupational danger of asbestos expsoure was published in 1964.

And yet, it wasn’t unitl the mid-1970s that asbestos use was widely banned, and even today, its use is not completely banned.

Selikoff hoped his findings would make the future brighter for workers, protecting them from such devastating illnesses as those suffered by the generations who had come before.  Sadly, Selikoff passed away in 1992, before ever seeing asbestos eliminated in America, or seeing the threat of mesothelioma become a thing of the past.

With such clear evidence of the link between asbestos and mesothelioma, why is this still even a question??

The results of a study published recently in The Journal of Thoracic and Cardiovascular Surgery supports the use of extrapleural pneumonectomy-based multimodal therapy in carefully selected patients with malignant pleural mesothelioma. The Journal is published by The American Association for Thoracic Surgery.
According to the research summary, the objective of the study was to evaluate the perioperative and long-term outcomes associated with extrapleural pneumonectomy for patients with malignant pleural mesothelioma. Pleural mesothelioma affects the lining of the chest cavity and lungs. Other forms of mesothelioma include pericardial, which affects the lining of the heart and is extremely rare; and peritoneal, which affects the lining of the abdomen. Mesothelioma is atributed almost exclusively to asbestos exposure.
According to the Multimedia Manual of Cardiothoracic Surgery, extrapleural pneumonectomy was introduced in the 1940s for the treatment of extensive infections of the lung and pleural space. Over the past 20 years, the extrapleural pneumonectomy technique has been modified and applied to the treatment of locally advanced malignant pleural mesothelioma, achieving substantial reductions in mortality. The surgery involves the removal of the lung with visceral and parietal pleurae, pericardium and diaphragm.
Researchers selected 70 patients between October 1994 and April 2008 to undergo the procedure. Prognostic factors included age, gender, side of disease, asbestos exposure, histology, positron emission tomography, date of surgery, neoadjuvant chemotherapy, completeness of cytoreduction, lymph node involvement, peioperative morbidity, adjuvant radiotherapy and pemetrexed-based chemotherapy.
The mean age of patients was 55 years. The median survival was 20 months, with a 3-year survival of 30 percent. Analyses showed improved survival for patients with asbestos exposure, negative lymph node involvement, and receipt of adjuvant radiation or postoperative pemetrexed-based chemotherapy.
The study was conducted by physicians from the University of Sydney, Department of Cardiothoracic Surgery, Royal Prince Alfred Hospital; The Baird Institute for Applied Heart and Lung Surgical; Department of Medical Oncology, Sydney Cancer Center, Royal Prince Alfred Hospital; and Department of Radiation Oncology, Sydney Cancer Center, Royal Prince Alfred Hospital; all in Sydney, Australia.

A recent report on WDIO-DT and WIRT-DT ABC stations 10 and 13 says approximately 1,000 Iron Range miners and their families have been screened as part of an ongoing study into the link between taconite mining and mesothelioma. The study is being directed by the University of Minnesota and the Minnesota Department of Health, and funded by the Minnesota State Legislature, which allocated $4.9 million to the project in April 2008.

An investigation into the link between taconite mining – which takes place in what is known as Minnesota’s Iron Range – began when state health officials noted an unusually high incidence of mesothelioma occurring in taconite mine workers. Mesothelioma is traditionally linked only to asbestos exposure. There is a theory that the taconite mineral may contain similar fibers to asbestos mineral.

Researchers began screening workers and their immediate family members in July. According to the news report, researchers say the study is on track. They would like to see about another 1,000 people, however. Analysis of the respiratory is estimated to take another 18 months.

This screening is one part of the comprehensive five-year study. There are four health studies associated with the project, including a mortality study under the direction of the Minnesota Department of Health and related to miner deaths; a cancer rate incidence study; a respiratory health assessment for miners or former miners (and expanded to include spouses or other close family that may have had secondary exposure to taconite dust), and an occupational exposure study.

Last year, we reported on the establishment of a mesothelioma research project in Minnesota, which is examining the possible link between taconite mining and mesothelioma. The five-year research program received $4.9 million in funding from the Minnesota state legislature in April 2008, and is being directed by the University of Minnesota in partnership with the Minnesota Department of Health.

This week, university researchers announced they are ready to begin recruiting current and former taconite workers on Minnesota’s Iron Range, and their spouses, to participate in a screening program.

Preliminary research actually began in Summer 2007, but got a boost from the legislature’s funding, allowing the study to expand significantly. The funding established the Minnesota Taconite Workers Lung Health Partnership task force.

There are four health studies associated with the project:
a motality study under the direction of the Minnesota Department of Health related to miner deathsa cancer rate incidence studya respiratory health assessment for miners or former minersan occupational exposure study
According to an update in the Star Tribune, which serves the Twin Cities, Minneapolis and St. Paul, “since last year, researchers have been collecting data they need to determine why Iron Range miners die from mesothelioma at higher rates than others.”

Researchers hope to recruit around 1,200 current and retired workers for the new screenings, plus about 800 of their spouses.

Mesothelioma has been linked exclusively to asbestos exposure, so this study seeks to determine what similarities may exist in the taconite mining industry and the taconite mineral that produce high incidences of mesothelioma among its workers.

A study published today in The New England Journal of Medicine reveals that Fire Department of New York (FDNY) firefighters and emergency medical services (EMS) workers who responded to the 9/11 attacks at the World Trade Center have suffered significant, persistent declines in lung functions. According to the report, exposure to World Trade Center dust created when the towers collapsed led to “large declines” in lung functions for FDNY rescue workers during the first year, and that “the declines were persistent, without recovery over the next 6 years, leaving a substantial proportion of workers with abnormal lung function.”

The study included 12,781 workers who were present at the WTC site between Sept. 11, 2001 and Sept. 24, 2001, which is 91.6 percent of the workers that were present. The report notes that the event exposed the workers – as well as those living and working in the surrounding area – to a dense cloud of pulverized building materials and chemical byproducts, including pulverized glass and cement, insulation fibers including asbestos, and toxic chemicals.

According to a report in The New York Times that summarizes the study findings, this is the first study to document long-term harm in a large group of firefighters and emergency medical workers who worked at Ground Zero. All of the subjects of the study had had previous lung function tests, providing a baseline for the study.

The study was authored by Dr. David J. Prezant, chief medical officer in the Office of Medical Affairs at the New York City Fire Department. The study was approved by the institutional review board at Montefiore Medical Center.

Results of the study revealed that firefighters, who had heavier exposure to dust by the nature of their work had greater first-year declines than EMS personnel, especially for firefighters who were present in the morning on 9/11, when the dust cloud was most intense after the buildings fell. However, researchers noted they were surprised to see “little or no recovery of average lung function during the 6-year follow-up period.” In fact, they noted continued decline in lung function among the study groups.

Normally, the study notes, “smoke inhalation during firefighting causes relatively mild and reversible respiratory impairment.” Additionally, according to the report, long-term effects of firefighting on pulmonary function also are normally mild.

The average loss of lung function for 9/11 rescue workers is about 10 percent. Most of the loss occurred within the first year after 9/11 exposure, with little or no subsequent recovery.

Thousands of workers injured at Ground Zero have been fighting for compensation from the City of New York. Last month about 10,000 plaintiffs reached a settlement agreement totaling $657.5 million, but a judge rejected the settlement shortly afterward, saying it did not provide enough compensation for the plaintiffs. The matter is now back in negotiations, and a new hearing is set for Monday, according to the Times.

University of Minnesota researchers made a call in mid-September for more participants in its study of a possible link between Iron Range taconite mines and mesothelioma. The five-year reserach program received $4.9 million in funding from the Minnesota state legislature in April 2008, and is being directed by the university in partnership with the Minnesota Department of Health.

The study was conceived as a result of an unusually high incidence of mesothelioma in taconite mine workers. Mesothelioma is currently linked exclusively to asbestos exposure. To day, more than 58 Iron Range mine workers have been diagnosed with mesothelioma.

In July, researchers began health screenings of former taconite workers and their families. To date, a little more than 100 people have participated in the screenings, although reserachers hope to examine around 1,200 people during the course of the study.

The call for more participants apparently raised some concerns among area residents about the program’s success. However, a report by KQDS Fox 21 News assures the public that the study is progressing as planned, and that the call for more participants is a natural part of the process.

The news report quotes Nancy Tekautz, who is a field supervisor for the taconite workers respiratory health study, as saying her clinic is nearly booked. “We believe the response has been very good and we just want to encourage it to continue,” she told KQDS.

KXMB News reports study director Dr. Jeffrey Mandel has sent about 300 letters to a random sampling of current and former Iron Range taconite workers, asking them to participate in the study. Participants will provide a medical and occupational history and submit to simple medical tests.

Researchers assure miners and their families that all study participants and individual medical information will remain confidential. For more information, visit the Minnesota Taconite Workers Health Study web site, or call the University of Minnesota toll free at 1-888-840-7590.
