Drug May Make Mesothelioma Cells More Sensitive to Radiation

sensitive to radiation

Scottish cancer researchers say they have found a way to make mesothelioma cells more sensitive to radiation.  Radiotherapy is one of the tools doctors can use to help slow progression of the asbestos cancer. It can also help alleviate mesothelioma symptoms.  But proteins expressed by mesothelioma cells can make them less sensitive to radiation. The Glasgow-based research team is getting around this protection with a sensitizing drug. The drug mimics a process that already happens in healthy people. Radiotherapy in the Treatment of Mesothelioma Radiotherapy is not usually the primary treatment for malignant mesothelioma. Most mesothelioma patients have chemotherapy as their first-line treatment.  But newer technology means that radiation can be more targeted than it used to be. This means … Continue reading Drug May Make Mesothelioma Cells More Sensitive to Radiation »

Supplement May Boost the Effectiveness of Mesothelioma Treatment

boost the effectiveness of mesothelioma treatment

A supplement that claims to increase oxygen in the tissues might boost the effectiveness of mesothelioma treatment.  That is the conclusion of researchers at Italy’s National Cancer Institute in Rome.  The group tested the supplement Cellfood (CF) on several types of cancer cells in the lab. They also gave the supplement to mice with implanted human mesothelioma tumors.  CF appeared to boost the effectiveness of mesothelioma treatment with radiation or chemoradiation.  What is Cellfood? Cellfood (Deutrosultazyme) is a nutraceutical produced by NuScience Corporation. A nutraceutical is a nutritional supplement that may function like a drug in some ways. According to NuScience, Cellfood contains colloidal minerals, amino acids, enzymes, and dissolved oxygen. Lab studies show that it has antioxidant effects and … Continue reading Supplement May Boost the Effectiveness of Mesothelioma Treatment »

Signs of Peritoneal Mesothelioma After Radiotherapy

signs of peritoneal mesothelioma after radiotherapy

Japanese researchers are reminding doctors to watch for signs of peritoneal mesothelioma in people who have undergone past radiotherapy.  Many cancer patients undergo radiotherapy. Radiation disrupts the DNA inside cancer cells. This can help keep these malignant cells from replicating and spreading.  But radiation treatment also has a downside. It can cause cellular changes in healthy cells, too. This can cause side effects right away, or decades later.  As more people have radiation and survive, scientists at the Shinshu University School of Medicine say more of them could develop radiation-related mesothelioma later in life. But the signs of peritoneal mesothelioma years after radiation are easy to miss. Peritoneal Mesothelioma Case Study The new report is based on the case of … Continue reading Signs of Peritoneal Mesothelioma After Radiotherapy »

IMRT for Mesothelioma: Barriers to Completing Treatment

IMRT for mesothelioma

MD Anderson researchers say too many patients who might benefit from IMRT for mesothelioma never complete the treatment. The problem could be impacting their survival. Intensity Modulated Radiotherapy (IMRT) is a type of targeted radiation. It is designed to direct as much radiation as possible into the mesothelioma tumor without harming the surrounding tissue.  Patients who have a combination of surgery, chemotherapy, and IMRT for mesothelioma have the best odds of survival. But at MD Anderson Cancer Center, only two thirds of eligible patients completed IMRT after mesothelioma surgery. The new study aimed to find out why. Trimodal Therapy and Mesothelioma Survival Malignant mesothelioma rarely responds to a single cancer therapy. Trimodal therapy combines several different treatments to maximize success.  … Continue reading IMRT for Mesothelioma: Barriers to Completing Treatment »

Adjuvant Radiotherapy Most Effective for Pleural Mesothelioma in Early Stages

adjuvant radiotherapy for esothelioma

New research shows adjuvant radiotherapy is most likely to help pleural mesothelioma patients in the early stages of the disease. By the time mesothelioma is at Stage III or Stage IV, adjuvant radiotherapy is unlikely to improve survival. Researchers at MD Anderson Cancer Center in Texas conducted the study on more than 2,500 pleural mesothelioma patients. Their results appear in the most recent issue of the Journal of Thoracic Disease. The study could help mesothelioma patients and doctors make more informed choices about their care. Defining the Stages of Pleural Mesothelioma The four stages of mesothelioma relate to the severity of the cancer and how far it has spread. In Stage I mesothelioma, the tumor is confined to the pleural … Continue reading Adjuvant Radiotherapy Most Effective for Pleural Mesothelioma in Early Stages »

Palliative Radiotherapy for Mesothelioma Produces “Substantial Treatment Response”

palliative radiotherapy for mesothelioma

Doctors in Pennsylvania may have found a way to boost the effectiveness of palliative radiotherapy for pleural mesothelioma. Palliative radiotherapy is used to help with mesothelioma symptoms. It uses lower doses of radiation. Doctors do not expect to treat mesothelioma with palliative radiotherapy. But researchers at the University of Pennsylvania think it could also be a treatment. They combined palliative radiotherapy with a special kind of gene therapy. The gene therapy affects the immune system. They say the combination produced a “substantial treatment response” in a man with mesothelioma. Immuno-gene Therapy and Palliative Radiotherapy Immuno-gene therapy uses genes to stimulate the immune system against cancer. In the new Pennsylvania case study, a 67-year-old man with mesothelioma received immuno-gene therapy. Doctors … Continue reading Palliative Radiotherapy for Mesothelioma Produces “Substantial Treatment Response” »

Radiotherapy for Mesothelioma Doubles Survival in New Study

Radiotherapy for mesothelioma

Italian researchers presenting at an international conference this week say the right kind of radiotherapy for mesothelioma can dramatically boost survival. Radiation oncologist Marco Trovo and his colleagues at the University Hospital of Udine conducted the new mesothelioma research. They studied 108 pleural mesothelioma patients whose tumors could not be completely removed with surgery. Pleural mesothelioma affects the membrane around the lungs and is usually fatal within a year. But in the new study, more than half of the patients who had high doses of targeted radiotherapy in just the right area were still alive two years later. In contrast, just over a quarter of the patients who had palliative radiotherapy for mesothelioma lived to two years. Curative Versus Palliative … Continue reading Radiotherapy for Mesothelioma Doubles Survival in New Study »

Adjuvant Radiotherapy for Mesothelioma Extends Survival

The largest study ever conducted on adjuvant radiotherapy for mesothelioma shows that it can help patients live longer. Pleural mesothelioma is a rare cancer that tends to be highly resistant to standard treatments. Doctors usually have to use a combination of treatments to attack it. These may include chemotherapy, radiotherapy, surgery, and/or immunotherapy. But there are still many questions about what combination of therapies to use and in what order. Adjuvant radiotherapy for mesothelioma is radiation delivered prior to surgery. Now, radiation oncology researchers in Texas say this approach can extend mesothelioma survival. Killing Mesothelioma Cells with Radiation Mesothelioma cells are hard to kill. Chemotherapy with Alimta (pemetrexed) and cisplatin is the most common treatment. But mesothelioma tumors usually start … Continue reading Adjuvant Radiotherapy for Mesothelioma Extends Survival »

Radiation May Help Mesothelioma Immunotherapy Treatment Work Better

mesothelioma radiation treatment

Hypofractionated radiation for mesothelioma could change how doctors treat this rare cancer.  Researchers in Toronto, Canada have been testing hypofractionated radiation in mesothelioma surgery patients. They have used it to shrink tumors before lung-removing EPP surgery. Hypofractionated radiation is faster than than standard radiation. It may also cause fewer side effects. Now, doctors want to know what else this type of radiation might be good for. They plan to test how well hypofractionated radiation works with less radical mesothelioma surgery. There is also evidence that hypofractionated radiation may strengthen mesothelioma immunotherapy treatment. Radiation Before Mesothelioma Surgery Doctors at the Princess Margaret Cancer Center in Toronto ran a clinical trial called SMART. SMART stands for Surgery for Mesothelioma After Radiation Therapy. … Continue reading Radiation May Help Mesothelioma Immunotherapy Treatment Work Better »

Precision Radiotherapy Method May Reduce Local Recurrence of Mesothelioma After Surgery

A radiation delivery method called tomotherapy may be more effective than conformal radiation therapy at keeping mesothelioma tumors from growing back at the original spot after surgery. That is the conclusion of UCLA researchers who compared tomotherapy and 3D conformal radiation therapy (CRT) in 45 patients with advanced pleural mesothelioma over an 8 year period. Of the forty-five consecutive patients, 23 received 3D-CRT and the other 22 received tomotherapy. Kaplan-Meier analysis was used to calculate overall survival, the time it took for a tumor to start regrowing in the same place, and the time it took for metastatic tumors to start appearing outside of the treatment field. Tomotherapy and 3D-CRT are both methods of delivering radiation into a mesothelioma tumor … Continue reading Precision Radiotherapy Method May Reduce Local Recurrence of Mesothelioma After Surgery »
