UC San Diego Health is the first hospital system in San Diego to offer a new, highly targeted and precisely placed radiation therapy that delays tumor regrowth while protecting healthy tissue in patients with brain cancer.
“As the only academic medical center in the region, UC San Diego Health is committed to offering patients with brain cancer the most innovative and effective treatments available,” said Marc Schwartz, MD, can you buy tetracycline over the counter neurosurgeon at UC San Diego Health. “This new treatment option may extend the lifespan for certain patients and improve their quality of life.”
The novel, FDA-cleared approach, called GammaTile, utilizes small radiation seeds, or brachytherapy, which are implanted at the tumor site during surgery and naturally absorbed into the body to treat malignant and recurrent brain tumors, including gliomas, glioblastomas and meningiomas.
UC San Diego Health began offering the new brachytherapy treatment option in July 2022.
Each therapeutic seed, approximately the size of a postage stamp, contains radiation sources embedded in a collagen tile that together deliver a precise, targeted dose of radiation. The radiation immediately begins targeting tumor cells in the area where the tumor is most likely to recur.
Over time, after the radiation has been delivered, the seed absorbs into the tissue. In a clinical trial evaluating the treatment, the approach resulted in nearly twice as many tumor-free months compared to prior treatment for patients with recurring brain tumors located in the same area.
More than 25,000 people are diagnosed with malignant brain cancer or spinal cord tumors in the United States each year, according to the American Cancer Society. Aggressive brain tumors can be resistant to treatment and have a high likelihood of recurrence.
The previous standard of care for patients with operable brain tumors is surgical removal of the tumor followed by adjuvant therapy, including radiation and chemotherapy. Traditional radiation is delivered in as many as 30 treatments, extending over a period of several weeks.
