Renal cell carcinoma (RCC) presents an interesting challenge in radiation oncology. Improved systemic therapy has significantly prolonged survival. Modern imaging has allowed practitioners to effectively identify patients with oligometastatic disease. Conventionally fractionated radiation therapy is a first-line treatment option for palliation of bone metastases, including the spine, but has limited efficacy and durability. Conventional treatment may not be sufficient in metastatic RCC because of the disease's relative radioresistance. Improved technology, including custom immobilization and on-board treatment imaging, has allowed ultra-high-dose radiation therapy, or stereotactic radiosurgery (SRS), to effectively treat metastatic disease in the spine. Safety and efficacy have already been established for intracranial disease and data are emerging for extracranial metastasis. Spine SRS offers local control rates and durable pain improvement in up to 90% of patients. Many series have already reported its effectiveness, and prospective multi-institutional trials are underway. Spine SRS should be strongly considered in select patients with refractory or oligometastatic disease.

The NCCN Guidelines for Prostate Cancer address staging and risk assessment after a prostate cancer diagnosis and include management options for localized, regional, and metastatic disease. Recommendations for disease monitoring and treatment of recurrent disease are also included. The NCCN Prostate Cancer Panel meets annually to reevaluate and update their recommendations based on new clinical data and input from within NCCN Member Institutions and from external entities. This article summarizes the panel’s discussions for the 2021 update of the guidelines with regard to systemic therapy for metastatic castration-resistant prostate cancer.

The NCCN Guidelines for Prostate Cancer include recommendations regarding diagnosis, risk stratification and workup, treatment options for localized disease, and management of recurrent and advanced disease for clinicians who treat patients with prostate cancer. The portions of the guidelines included herein focus on the roles of germline and somatic genetic testing, risk stratification with nomograms and tumor multigene molecular testing, androgen deprivation therapy, secondary hormonal therapy, chemotherapy, and immunotherapy in patients with prostate cancer.
