Because renal cell carcinoma (hypernephroma) has very little radiation sensitivity, radiation therapy (radiotherapy) is used only in advanced stages of the disease to treat metastases (daughter tumors). This therapy serves exclusively to alleviate symptoms.
Further notes
- Stereotactic ablative radiotherapy (SABR): method in which high-energy radiation (e.g., photons) is used to destroy tumor tissue with high precision from the outside with few treatments (1-6) [S3 guideline].No prospective randomized trial data are available on ablative therapy methods for small renal tumors.
