Canadian doctors say they have found a correlation between the total thickness of a mesothelioma patient’s tumors and their likelihood of responding to treatment.

Thickness of Mesothelioma Tumors Correlate with Survival

Mesothelioma Tumor Thickness and Survival

Total tumour thickness had a significant impact on overall survival and disease-free survival.

Researchers in Toronto have just released what they are calling “extremely encouraging” results of a study comparing mesothelioma tumor thickness to outcomes. Surviving Mesothelioma has published a new article on these findings. Click here to read it now.

The University of Toronto study included 65 newly-diagnosed patients with pleural mesothelioma. The thickness of their tumors was measured with imaging studies and compared to their eventual treatment responses.

“Total tumour thickness had a significant impact on overall survival and disease-free survival in univariate analysis,” writes author Marc de Perrot, MD, a thoracic surgeon at Toronto General Hospital. “In multivariate analysis, total tumour thickness remained an independent predictor of survival…”

According to the article in the European Respiratory Journal, people with thicker tumors had higher tumor volume and lower odds of mesothelioma survival. Thickness of mesothelioma tumors on the diaphragm had the closest correlation to length of life.

“The researchers call these results encouraging because they suggest a way to refine the cancer staging process and make more informed decisions about radical mesothelioma treatment, which can be very challenging” says Alex Strauss, Managing Editor of Surviving Mesothelioma.
