Sanford Markowitz, MD, PhDSanford Markowitz, MD, PhD, medical oncologist, UH Seidman Cancer Center; and Francis Wragg Ingalls Professor of Cancer Genetics, Case Western Reserve University School of Medicine, and a team of researchers published findings in the April issue of Science Translational Medicine on the effects of aspirin on colorectal cancer risk in people with the gene 15-hydroxyprostaglandin dehydrogenase (15-PGDH) RNA. The study, which included nearly 128,000 participants, found that people with high levels of 15-PGDH in their colons could cut their colorectal cancer risk in half by taking aspirin. Researchers now hope to develop a cost-effective test for measuring the levels of 15-PGDH in the colon to determine which patients would benefit from aspirin therapy.

Afshin Dowlati, MDAfshin Dowlati, MD, Director, Thoracic Oncology Program, Rosalie and Morton A. Cohen Chair in Oncology, Endowed Director of the Gries Center for Cancer Drug Development, UH Seidman Cancer Center; and Professor of Medicine, School of Medicine, a research team published two studies that have the potential to advance the treatment of small cell lung cancer (SCLC), one of the fastest-growing cancers.

The first study, published in the Journal of Thoracic Oncology, found a new mutation in SCLC, called RET, that was linked to rapid cell growth. Examining specimens in its database of metastatic SCLC tumors, the team discovered that the RET protein was sensitive to two new targeted therapies, ponatinib and vandetanib. The second study, published in PLOS One, focused on analyzing SCLC tumors to examine drug sensitivity to predict which drugs would be most effective at slowing tumor growth.
