Understanding Stereotactic Radiosurgery (SRS)

Stereotactic radiosurgery (SRS) has changed the way we treat cancer. It’s precise and effective. We’ll look into what SRS is, how it started, and what makes it different from regular radiation therapy.

Definition and Basic Principles

SRS is a method that uses focused radiation to treat tumors and lesions. It doesn’t cut into the body like surgery does. Instead, it sends high doses of radiation to exact spots, protecting healthy tissues nearby. The basic principle of SRS is its ability to target lesions with great accuracy using advanced imaging and radiation systems.

The process starts with imaging, like MRI and CT scans, to find the target area. Then, software plans the best radiation dose. Last, machines like the Gamma Knife or linear accelerators deliver the radiation.

Historical Development of SRS

Lars Leksell, a Swedish neurosurgeon, first thought of SRS in the 1950s. It was first used for conditions like trigeminal neuralgia and arteriovenous malformations. Over time, SRS has grown, treating more conditions like brain tumors and metastases.

Studies show SRS has come a long way. It’s now a key part of radiation oncology thanks to technology and technique improvements.

How SRS Differs from Conventional Radiation

SRS is different from regular radiation therapy in several ways. It uses higher doses in fewer fractions, making it more effective for some tumors. It also uses advanced systems for precise radiation delivery, protecting healthy tissues.

Characteristics	SRS	Conventional Radiation
Dose per Fraction	High	Lower
Number of Fractions	Fewer (often single)	Multiple
Targeting Precision	High	Variable

SRS’s precision and effectiveness make it a valuable treatment option. As technology improves, SRS will become even more important in cancer treatment and radiation oncology.
