New Treatments Show Promise for Two of the Most Deadly Types of Cancer
Summary
New treatments show promise for glioblastoma, a common and aggressive brain cancer, and for a rare type of ovarian cancer called clear cell carcinoma. Researchers found that a minimally invasive laser surgery may extend survival and improve quality of life for brain cancer patients, and immunotherapy might work for some ovarian cancer patients.Key Facts
- Glioblastoma is an aggressive brain cancer with no cure, often treated by surgery, radiation, or chemotherapy.
- A laser treatment involves a small hole drilled in the skull to insert a robot-controlled laser that kills tumor cells with heat.
- Patients with 91% or more of their brain tumor destroyed by laser treatment lived about 2.1 years on average after diagnosis, longer than typical surgery survival of 1.5 years.
- Laser treatment is less invasive, requires only a small incision, a short hospital stay, and helps maintain quality of life.
- The laser procedure could be an option even for patients who might normally have surgery.
- Researchers in Japan found some clear cell ovarian cancers respond well to immunotherapy by targeting a protein called IL-17.
- IL-17 helps create an environment around tumors that boosts the immune response.
- Both treatments aim to improve survival and quality of life for patients with these difficult-to-treat cancers.
