Table 2. Comparison between the favorable and unfavorable prognosis groups.

Variables	Favorable prognosis group	Unfavorable prognosis group	p value
PTV (cm3)	≤279	>304
Total dose (Gy10)	>60	≤60
NTNL-VBED20 (%)	≤40.8	>40.8
Outcome
No of patients	30	12
Local PFS (mo)	16.0	4.8	<0.001
Overall PFS (mo)	7.9	4.3	0.022
