Table 5. One and 2-year survival and local control.

Parameter	1 year (%)	2 year (%)
Overall survival	72	62
Progression free survival	32	23
Local control	86	80
Local control of lesions ≤ 50 cc	–	84
Local control of lesions > 50 cc	–	62

One- and 2-year overall survival (OS), progression free survival (PFS) and local control (LC) were defined as the time from first fraction of treatment to death (OS), progression of disease at any site (PFS), or local progression of treated lesion (LC) and calculated using Kaplan-Meier’s method.
