Abstract
Renal cell carcinoma (RCC) is an aggressive malignancy that carries a poor prognosis,
especially in patients presenting with advanced stage. Primary treatment for localized
RCC is surgical resection however, a significant number of patients still develop
locoregional and distant metastasis after curative resection. In metastatic disease,
radiation therapy (RT) has been used for palliation routinely for brain and other
extracranial lesions with respectable response rates. However, RT for primary RCC
has questionable benefit. In this article, the authors discuss the evidence with regards
to the role of RT in primary RCC either as a primary treatment, adjuvant treatment,
or preoperatively to improve resection outcomes. In addition, novel RT techniques
such as stereotactic body radiation therapy and its use in RCC management are also
addressed. Finally, the authors discuss the techniques and doses of RT for primary
RCC.
