Not only is mesothelioma extremely deadly, there is often very little doctors can to do help a patient diagnosed with this form of cancer. In fact, some of the most commonly used forms of surgical intervention can actually create more tumors than were originally present.
This phenomenon is known in the medical community as procedure tract metastases (PTM). PTM are a series of small tumors that grow along the path where a surgical incision was made or the tract in which a pleural catheter was placed in a patient with malignant mesothelioma. Essentially, PTMs occur following surgery or catheterization to treat mesothelioma and allow the cancer to spread to other parts of the body by creating a series of small tumors.
According to a recent news article from News 6, British researchers are conducting clinical trials on using radiotherapy to prevent PTMs from forming or spreading cancer. Currently researches in UK and other nationals are recruiting patients for surgical and large bore procedures in malignant pleural mesothelioma and radiotherapy trial (SMART). This multi-center randomized trial hopes to evaluate the efficacy of radiotherapy within 42 days of plural surgery in halting development of PTM tumors. Some patients will be randomly selected to only have radiotherapy if a PTM develops.
