Abstract

Purpose: Stereotactic body radiotherapy (SBRT) has become an excellent non-invasive alternative for many patients with primary renal cell carcinoma (RCC) and adrenal malignancies (AM). The aims of this study were to analyse how tumor-, patient- and treatment-related factors may influence the outcomes and side effects of SBRT and to assess its benefits as an alternative to surgery. Methods: This retrospective, multicenter study included 25 lesions in 23 patients treated with SBRT using different devices (LINAC, CyberKnife® and Tomotherapy®). A multivariate linear regression was used for the statistical study. Results: Local control time was higher than six months in more than 87% of patients and treatment response was complete for 73.68%. There was an overall 2-year survival of 40% and none of the deaths were secondary to renal or adrenal local progression. Patients treated with lower total radiation dose (mean [m] = 55 Gy) but less fractions with more dose per fraction (> 8.5 Gy) showed better outcome. Patients with previous chemotherapy and surgery treatments also showed higher complete response and disease-free survival (> 6 months). Conclusions: This study highlights the importance of ultra-hypofractionated regimens with higher doses per session. Thus, the referral of patients with RCC and AM to Radiotherapy and Oncology departments should be encouraged supporting the role of SBRT as a minimally invasive and outpatient treatment.
