What is attributed to the greatest improvement in survival rates of patients with metastatic brain cancer?

Radiation therapy
Radiosurgery
Surgical resection
Chemotherapy

The correct answer is: Radiosurgery

Radiosurgery has shown the greatest improvement in survival rates for patients with metastatic brain cancer due to its ability to deliver high doses of radiation precisely to the tumor while minimizing damage to surrounding healthy tissue. This technique allows for targeted treatment of tumors that are often difficult to access surgically, especially in cases where patients have multiple lesions or are not good candidates for traditional surgery. Studies indicate that patients receiving radiosurgery tend to experience less morbidity compared to those undergoing more invasive procedures, leading to improved overall survival. Additionally, radiosurgery can be performed in an outpatient setting, meaning that patients can return to their normal activities more quickly, which is beneficial for quality of life. The effectiveness of radiosurgery, combined with its safety profile, has cemented its role as a cornerstone in the management of metastatic brain tumors, greatly influencing treatment protocols and improving patient outcomes in this challenging population.
