Doctors Describe "Concrete Therapeutic Approach" for Mesothelioma

ByAlex Strauss

A team of medical researchers in Italy have achieved what they are calling “excellent” tumor control and survival results in malignant pleural mesothelioma patients using a combination of surgery, chemotherapy, and radiotherapy. Caused by exposure to asbestos, mesothelioma typically spreads quickly across the lung-encasing membrane called the pleura. There is no known cure but treatments are improving. In the current prospective study, 20 malignant pleural mesothelioma patients underwent radical pleurectomy/decortication followed by high doses of radiation. After surgeons removed as much of the visible mesothelioma tumor and surrounding tissue as possible, patients received 50Gy of radiation to the effected side of their chest, delivered in 25 fractions. Regions of particular concern for mesothelioma regrowth got an extra radiation “boost” to…

Mesothelioma Chemotherapy Could Get a Boost from Altered Virus

ByAlex Strauss

An altered form of a virus that typically causes respiratory illness may help boost the effectiveness of chemotherapy for mesothelioma. In a study published in the Journal of Thoracic Oncology, researchers found that deleting a gene from adenoviruses made the drugs pemetrexed and cisplatin more cytotoxic to mesothelioma cells in the lab. In its unaltered state, the adenovirus is the virus most closely associated with respiratory problems, ranging from the common cold to pneumonia, croup and bronchitis.  It can also cause gastroenteritis, cystitis, and conjunctivitis. However, when it is altered in the lab by removing a particular gene, it can become a powerful ally in the fight against hard-to-treat cancers like mesothelioma. In the latest study, researchers first deleted the E1B-55kD…

A Second-Line Option for Mesothelioma?

A Second-Line Option for Mesothelioma?

ByAlex Strauss

Although survival was not significantly extended, the chemotherapy drug vinorelbine might be a treatment option for mesothelioma patients whose cancer has returned after first-line chemotherapy with pemetrexed. A new study on vinorelbine as a second-line treatment finds that the drug is “moderately active” in mesothelioma patients who were initially treated with pemetrexed-based chemotherapy. Pemetrexed (Alimta), along with a platinum-based drug like cisplatin, is the primary first-line drug therapy for mesothelioma. But vinorelbine is gaining attention as a possible option for mesothelioma, in part because it is available in a less expensive generic form. In “Vinorelbine in pemetrexed-pretreated patients with malignant pleural mesothelioma”, the Italian authors detail the results of their study on 59 patients with unresectable pleural mesothelioma.  These patients…

Chemical in Wine May Improve Mesothelioma Treatment

ByAlex Strauss

There’s new evidence that a compound found in red wine may help improve the effectiveness of chemotherapy treatment for malignant pleural mesothelioma. Last year, a team of Korean researchers released the world’s first study on the mesothelioma-fighting power of resveratrol, a natural phenol derived from the skin of red grapes and found in red wine and grape juice. Now, the same team says resveratrol also appears to enhance the chemosensitivity of malignant mesothelioma cells. Study author Yoon-Jin Lee and colleagues discovered  a synergistic cancer-fighting effect in mesothelioma cells treated with both resveratrol and clofarabine, a prescription drug often used to treat acute lymphoblastic leukemia. Together, resveratrol and clofarabine “induced a strong cytotoxic effect” by influencing levels of the tumor suppressor,…

Repeat HIPEC Improves Mesothelioma Survival

ByAlex Strauss

If one cytoreductive surgery and HIPEC procedure for mesothelioma is good, subsequent treatments may be even better. That is the central message of research conducted at the Moffitt Cancer Center in Florida. The study’s aim was to assess overall survival among peritoneal mesothelioma patients who had not just one, but two or more rounds of heated intraperitoneal chemotherapy (HIPEC) after cytoreductive surgery. The cytoreduction/HIPEC approach has become popular for peritoneal mesothelioma, a treatment-resistant cancer of abdominal membranes caused by asbestos. Cytoreductive surgery involves removing as much of the mesothelioma tumor as possible from the abdomen. Because the shape and spreading pattern of mesothelioma tumors make complete cytoreduction difficult, the surgery is often followed by a rinse with a heated solution…

Value of Mesothelioma Surgery Challenged for Healthy Patients

Value of Mesothelioma Surgery Challenged for Healthy Patients

ByAlex Strauss

New research conducted in Italy and presented at the 15th World Conference on Lung Cancer in Sydney, Australia suggests that mesothelioma surgery – no matter what kind – may not offer a survival advantage over medical management for the healthiest of patients. Mesothelioma is a rare but aggressive malignancy that is highly resistant to standard cancer treatments. The two types of mesothelioma surgery considered to be options for people with resectable cancer are pleurectomy decortication (P/D) or extrapleural pneumonectomy (EPP). While EPP is more radical than P/D because it involves removing a lung, both carry a heavy risk of complications and, according to the Italian researchers, may not be of value for certain patients. The study reviewed data from 1,365…

Needle Biopsy “Simple, Safe & Accurate” for Mesothelioma

ByAlex Strauss

Mesothelioma researchers in China say a biopsy method that involves a single skin puncture can produce good diagnostic results for mesothelioma patients with little pain or risk. The study focused on percutaneous (through the skin) biopsy in patients who had unexplained fluid buildup or swelling in their abdomens. Abdominal distension and fluid buildup (called ascites) can be signs of peritoneal mesothelioma, a rare but aggressive cancer of the abdominal lining caused by exposure to asbestos. Peritoneal mesothelioma accounts for less than 30% of all mesothelioma cases. Because the symptoms may be vague and often develop many decades after asbestos exposure, peritoneal mesothelioma can be especially challenging to diagnose.  Misdiagnosis and under-diagnosis are not uncommon. In the newest study on percutaneous…

Immunotherapy Drug May Be Option for Advanced Mesothelioma

Immunotherapy Drug May Be Option for Advanced Mesothelioma

ByAlex Strauss

Advanced malignant mesothelioma patients who have not responded to standard chemotherapy may have an alternative in a new drug called tremelimumab. An open-label, single-arm, phase 2 trial of the drug has found it to be safe and tolerable and to have “encouraging clinical activity” in advanced malignant mesothelioma that cannot be surgically removed. Tremelimumab is a monoclonal antibody that acts on a particular downregulator of the immune system called cytotoxic T-lymphocyte antigen 4 (CTLA4). The goal of tremelimumab is to inhibit the immune system tolerance to tumors, which tends to allow them to grow unchecked. When CTLA4 is reactivated with a drug like tremelimumab, it regains its ability to attack tumors. The new published study on tremelimumab for mesothelioma was…

Mesothelioma Surgery May Have Added Benefit

ByAlex Strauss

Cancer researchers at Wake Forest University have found another benefit to the cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) combination used to treat peritoneal mesothelioma and other abdominal cancers: the control of fluid buildup. Fluid accumulation in the abdomen because of peritoneal mesothelioma or another type of cancer is known as ascites. Left untreated, ascites can cause bloating, discomfort, disfiguration, and shortness of breath when it interferes with the movement of the diaphragm. While patients with peritoneal mesothelioma, an aggressive cancer of the peritoneal surface, can have this fluid drained off, it often reaccumulates. But the new Wake Forest research suggests that CRS/HIPEC may offer a more permanent solution. Fifteen percent of the cancer patients in the study had…

Treatment Uses Herpes Virus to Shrink Mesothelioma Tumors

ByAlex Strauss

Researchers at a hospital in Sheffield, England are testing a potential new mesothelioma treatment based on the same virus that causes herpes. The small-scale trial is the first in the world to test the modified herpes simplex virus, HSV1716, in human mesothelioma patients. HSV1716 has been genetically engineered to infect and kill cancer cells without harming healthy cells. In laboratory studies on mesothelioma and some other cancers, it has been shown to be effective at shrinking tumors while causing limited toxicity. Just as significantly, HSV1716 increased survival rates among mice with various human cancers. The Phase I/II trial at Sheffield Experimental Cancer Medicine Centre is the next stage in development of HSV1716 as a viable mesothelioma treatment. The goal of…
