Nearby Tumor Progression-Free Survival LTP created at follow-up in 29 out of 267 tumors (10.9 ), 24/193 (12.four ) in the upfront repeat regional treatment group and 5/74 (six.8 ) in the NAC group (Figure 2). General crude comparison in between the two groups showed no considerable distinction in LTPFS (HR, 0.621; 95 CI, 0.236.635; p = 0.335) (Table 7). Overall, 1-year LTPFS was 92.7 , 3-year LTPFS was 84.8 , and 5-year LTPFS was 84.8 . One-, three- and five-year LTPFS had been respectively 96.eight , 88.eight , and 88.8 for the NAC group and 91.4 , 83.5 , and 83.5 for the upfront repeat neighborhood remedy group.Cancers 2021, 13,ten ofFigure 2.
