PD-L1 Expression and Mesothelioma Prognosis

PD-L1 expression and mesothelioma prognosis

The largest study yet on PD-L1 expression and mesothelioma prognosis shows that patients with more of this protein in their cells have poorer odds of survival. Programmed death ligand 1 (PD-L1) helps cancer cells evade immune system attack.  Other studies have suggested a link between PD-L1 expression and mesothelioma prognosis. But the new meta-analysis performed by two Chinese researchers appears to confirm it with an even bigger data set.  Understanding Mesothelioma Prognosis Malignant mesothelioma is an uncommon cancer that typically carries a poor prognosis. Many people diagnosed with mesothelioma lose their lives to the illness within a year.  But there are also many exceptions. Some mesothelioma survivors live for decades after a mesothelioma diagnosis. Australian Paul Kraus is an example. … Continue reading PD-L1 Expression and Mesothelioma Prognosis »

PD-L1 Inhibitor Nivolumab Works Well in New Mesothelioma Study

PD-L1 inhibitor nivolumab

A study of the PD-L1 inhibitor nivolumab showed “safety and efficacy” in mesothelioma patients who failed with other treatments.  Nivolumab is a type of immunotherapy marketed under the brand name Opdivo. It is similar to pembrolizumab (Keytruda) in that it blocks the tumor-promoting protein PD-L1. Nivolumab is most often used for patients with non-small cell lung cancer.  A multicenter phase II Japanese study found the PD-L1 inhibitor nivolumab helped a group of pleural mesothelioma patients live longer. Just as importantly, the side effects of the drug were “manageable”.  Human Trial of PD-L1 Inhibitor Nivolumab Chemotherapy with pemetrexed (Alimta) and cisplatin is the standard first-line treatment for pleural mesothelioma. But many patients either do not respond to chemotherapy or they stop … Continue reading PD-L1 Inhibitor Nivolumab Works Well in New Mesothelioma Study »

Shorter Mesothelioma Survival Again Linked to Higher PD-L1 Levels

shorter mesothelioma linked to protein

Patients with the rarest mesothelioma subtypes tend to experience shorter mesothelioma survival. Now, new mesothelioma research suggests that may have something to do with a protein called PD-L1. French researchers studied the PD-L1 levels in the tumors of 214 mesothelioma patients. They compared the levels with each patient’s subtype and their treatment outcome.  The results may help explain cases of shorter mesothelioma survival, especially among patients with sarcomatoid or biphasic mesothelioma subtypes.  PD-L1 Levels and Shorter Mesothelioma Survival Programmed death ligand 1 (PD-L1) is one of the proteins that helps mesothelioma cells and other cancers “hide” from the immune system.  Normally, the immune system finds and destroys renegade cells. But if a patient’s mesothelioma tumor expresses higher amount of PD-L1, … Continue reading Shorter Mesothelioma Survival Again Linked to Higher PD-L1 Levels »
