abstract = {Von Hippel-Lindau disease (VHL) is a hereditary disorder
associated with malignant tumors including clear cell renal
cell carcinoma (ccRCC). Partial nephrectomy is complicated
by multilocular tumor occurrence and a high recurrence rate.
The aim of this study was to evaluate the potential of
stereotactic body radiotherapy (SBRT) as an alternative
treatment approach in VHL patients with multiple ccRCC.
Patients with VHL and a diagnosis of ccRCC were enrolled.
SBRT was conducted using five fractions of 10 Gy or eight
fractions of 7.5 Gy. The primary endpoint was local control
(LC). Secondary endpoints included alteration of renal
function and adverse events. Seven patients with a total of
eight treated lesions were enrolled. Median age was 44
years. Five patients exhibited multiple bilateral kidney
cysts in addition to ccRCC. Three patients underwent at
least one partial nephrectomy in the past. After a median
follow-up of 43 months, 2-year LC was $100\%,$ while 2-year
CSS, 2-year PFS and 2-year OS was $100\%,$ $85.7\%$ and
$85.7\%,$ respectively. SBRT was very well tolerated with no
acute or chronic toxicities grade ≥ 2. Mean estimated
glomerular filtration rate (eGFR) at baseline was 83.7 ±
13.0 mL/min/1.73 m2, which decreased to 76.6 ± 8.0
mL/min/1.73 m2 after 1 year. Although the sample size was
small, SBRT resulted in an excellent LC rate and was very
well tolerated with preservation of kidney function in
patients with multiple renal lesions and cysts.},
