Dr. Mirsaeidi is a sarcoidosis expert. Sarcoidosis is a granulomatous lung disease with unknown etiology. He is interested in cancer-induced sarcoidosis. In his cohort of patients, he found that solid and hematologic cancers may initiate or accelerate sarcoidosis. Lung cancer, breast cancer, and lymphoma are some examples of this association. Dr. Mirsaeidi’s team also found that some miRNAs that are up-regulated in sarcoidosis may increase the risk of cancer. He is interested in finding the mechanism of cancer associated sarcoidosis.
