Dr. Amar Rewari Featured in Newsweek on Promising New Treatments for Glioblastoma and Ovarian Cancer

Dr. Amar Rewari was recently featured in Newsweek, where he provided expert commentary on two new studies offering hope for patients facing two of the most challenging cancers: glioblastoma and ovarian cancer.

The article, published August 21, 2026, covers research from Washington University School of Medicine on a minimally invasive laser treatment for brain tumors, along with a study from Kindai University in Japan identifying a biomarker that may predict which ovarian cancer patients respond to immunotherapy.

Dr. Rewari, Chief of Radiation Oncology at Luminis Health and Adjunct Assistant Professor at the Johns Hopkins University School of Medicine, discussed the significance of the glioblastoma findings, noting that the research provides important guidance on when laser therapy may be used most effectively. He highlighted its value for patients whose tumors are difficult to reach surgically or who face high risks from open brain surgery, emphasizing that for a disease without a cure, gains in both survival and quality of life are meaningful.

Addressing both studies, Dr. Rewari offered a measured perspective: while neither represents a cure, both give oncologists better tools to match the right treatment to the right patient — one of the most important ways cancer care continues to advance.
