Background: Surgical resection of brain metastasis is followed by adjuvant radiation in order to reduce the risk of local recurrence. Traditionally, adjuvant radiation was practiced in the form of whole brain radiation therapy that was associated with adverse neurocognitive outcomes and poor quality of life of the patients. In the recent times, stereotactic radiosurgery (SRS) is being practiced as the standard of care for treating brain metastasis cavity with good local control and improved the patient’s quality of life by sparing the normal tissues of adverse effects of radiation. Here, we describe procedure details for stereotactic planning of surgically resected brain metastasis. Materials and Methods: The step-by-step procedure for stereotactic planning of brain metastasis cavity has been described using a clinical scenario of brain metastasis. Results: The stereotactic radiation planning of brain metastasis cavity starts with the basic history and relevant evaluation of symptoms. Magnetic resonance imaging (MRI) of the brain is the imaging modality of choice. The radiation planning of brain metastasis cavity starts with computed tomography (CT) simulation and MRI of brain that should be done in a prescribed format to achieve uniformity in radiation planning. After CT and MRI image fusion, contouring of target, organs at risk (OAR), and radiation planning should be done. The plan evaluation includes target and OAR coverage index, conformity, homogeneity and gradient index, and beam arrangement. After radiation plan evaluation, treatment is delivered after quality assurance and dry run. Conclusion: The paper highlights the sequential process of radiation planning for SRT of brain metastasis cavity, starting from simulation, planning, evaluation of plan, and treatment.
