Partial Stereotactic Ablative Boost Radiotherapy in Bulky Non-Small Cell Lung Cancer: A Retrospective Study [Corrigendum]

Bai Y, Gao XS, Qin SB, et al. Onco Targets Ther.  2018;11:2571– 2579.

Recently the authors found two main errata in the text that need to be corrected.

On page 2571, Abstract, Results section, “Two-year overall survival was 55.6%. Two-year local control rate was  85.7%” should read “One-year overall survival was  64.9%. One-year local control rate was 100%”.

On page 2574, Response and survival outcomes section, 3rd and 4th sentences, “One-year over-all survival was 88.2%. Two-year overall survival was 55.6% (Figure 2A).” should read “One-year over-all survival was 64.9%. Two-year overall survival was 44.5% (Figure 2A).”

On page 2574, Response and survival outcomes section, 10th sentence, “Two-year local control rate was 85.7%. (Figure  2B).” should read “Two-year local control rate was 57.1%. (Figure 2B).”

On page 2575, Figure 2 legend, “(A) Kaplan–Meier plots of overall survival for all patients. One-year overall survival was  88.2%. Two-year overall survival was 55.6%. (B) Kaplan–Meier plots of local control for all patients. One-year local control rate was 100%. Two-year local control rate was 85.7%. (C) Patients with B90≥ 65% (n=19) achieved a higher local control rate than those with B90< 65% (n=11) (median survival=15.2 months vs 3.5 months, CI=6.8– 23.6 and 2.2– 4.9 months, respectively; P=0.010). (D) Patients with B80≥ 90% (n=20) achieved a higher local control rate than those with B80< 90% (n=10) (median survival=14.9 months vs 3.5 months, CI=3.4– 26.3 and 1.8– 5.2 months, respectively; P=0.045).” should read “(A) Kaplan–Meier plots of overall
survival for all patients. One-year overall survival was 64.9%. Two-year overall survival was 44.5%. (B) Kaplan–Meier plots of local control for all patients. One-year local control rate was  100%. Two-year local control rate was 57.1%. (C) Patients with B90≥ 65% (n=19) achieved a higher local control rate than those with B90< 65% (n=11) (median survival=15.2 months vs 3.5 months, CI=6.8– 23.6 and 2.2– 4.9 months, respectively; P=0.010). (D) Patients with B80≥ 90% (n=20) achieved a higher local control rate than those with B80< 90% (n=10) (median survival=14.9 months vs 3.5 months, CI=3.4– 26.3 and 1.8– 5.2 months, respectively; P=0.045).”

On page 2576, Discussion section, last sentence “Therefore, daily SABR was applied in our article and the 2-year local control rate was as high as 85.7%, even stage IV NSCLC were 40%.” should read “Therefore, daily SABR was applied in our article and the 1-year local control rate was as high as 100%, even stage IV NSCLC were 40%.”

Despite the correction in the text list as above, the Figures of Kaplan–Meier plots of overall survival and local control are correct, and the error doesn`t the change the overall findings reported in the paper. We can still conclude that “This retrospective study suggests that P-SABR is feasible and well tolerated in bulky NSCLC. Local control rate is encouraging, especially for the B90≥ 65% group, which may due to the ability of P-SABR to optimize BED with equivalent toxicity”. The authors apologize for this error.
