Asbestos Investigation

The BBC’s International News Service, in partnership with the International Consortium of Investigative Journalism (ICIJ), has recently released an investigative news report on the state of the global asbestos trade.

Asbestos exposure is the primary cause of malignant mesothelioma cancer. Following repeated exposure to the toxic mineral, symptoms can take as long as 20 to 50 years to arise and a patient’s life expectancy is often very poor since there is no cure for this cancer. Combining aggressive therapies has the potential to extend mesothelioma life expectancy by several months or more, but not all patients qualify for this treatment approach.

The BBC and ICIJ report features the story of Janice Tomkins, a mesothelioma patient in the Quebec Province, Canada. Tomkins represents a growing population across the globe as the rate of asbestos-related disease continues to rise. Since it usually takes decades to develop an asbestos-related disease, the projected incidence rate has been predicted to peak near 2020 considering the use of asbestos declined greatly after the 1970s.

Although more than 50 countries have banned or restricted asbestos, the white form of asbestos is still widely used in Brazil, China, India and Russia, and throughout many developing countries. Although it is not widely used in Canada, white asbestos (known as chrysotile) is heavily mined and exported to various countries. Russia is home to one of the largest asbestos mining operations in the world, producing nearly 1 million tons of asbestos per year. Russia produces almost half the world’s supply of asbestos and one mine near the city of Asbest is close to half the size of Manhattan.

The United States has yet to ban asbestos, but the toxic mineral is regulated and as long as a product has less than 1 percent asbestos it is considered in the United States to be free of asbestos. However, most U.S. residents are under the impression that asbestos was banned in the late-1980s. The Environmental Protection Agency (EPA) attempted to enact a ban in 1989, but the ban was thrown out by the Fifth Circuit Court of Appeals in 1991.

According to BBC’s report, “The WHO says 125 million people encounter white asbestos in the workplace, and the International Labour Organization (ILO) estimates that 100,000 workers die each year from all asbestos-related diseases.”

Mesothelioma Therapy: Heated Chemotherapy as a Treatment Option

Friday, July 30th, 2010

While recent clinical trials and research studies have made great advancements in understanding mesothelioma cancer, very few treatment options have been established for patients searching for a cure.

One form of treatment that has had recent success in prolonging the mesothelioma life expectancy of patients is hyperthermic intraperitoneal chemotherapy (HIPEC), a treatment that is still in the developmental process.

HIPEC is performed in combination with surgery and involves the use of a heated chemotherapy solution that is circulated throughout the abdominal cavity while the patient is still in the operating room. The high temperature of the solution has been found to increase the chemotherapy drug’s overall impact.

In a case earlier this year, a man from Grand Rapids, Michigan has survived two years after being diagnosed with peritoneal mesothelioma thanks to the developing heated chemotherapy option. Jesse Diaz was diagnosed in June 2007 and was later referred to Spectrum Health Hospital surgical oncologist Dr. Mathew Chung.

Dr. Chung has been working with the heated chemotherapy method and Mr. Diaz qualified for the treatment when he was diagnosed. According to Dr. Chung, “We call it the ’shake and bake procedure’ because we would remove everything, put some heated chemotherapy in the abdomen and literally shake the patients so the chemotherapy would circulate in the abdomen.”

This developing technique has made great strides for mesothelioma treatment in recent years. Dr. Chung says, “These patients have a 5-year survival rate of less than 25 percent. With this technique, up to 75 percent survive after five years.”

The average prognosis for mesothelioma patients is between four and 18 months, but Mr. Diaz has been cancer free two years. Considering this type of cancer is difficult to send into remission, this could be a breakthrough treatment option that may lead to other significant discoveries.
