Unfortunately, the original version of this article contained several errors made during final step of article production. In the results section (fourth sentence) of the Abstract, the incomplete sentence,”, 31.4% in high-risk group and 4.7% in treatment failure group; P < 0.001) and overall survival (5-year survival, 82.1%, 45.5%, and 14.7%, respectively; P < 0.001), was included incorrectly and it should be removed from the abstract. In the section of Development of the risk-stratification model of the main Results (second paragraph, fourth sentence), quotation marks were included inappropriately and it should be corrected as follows: “The treatment failure rate in patients with a Deauville score of 3 and a low NCCN-IPI risk was similar to that in patients with a Deauville score of 1 or 2 and a low-intermediate NCCN-IPI risk, although the number of patients in a Deauville score of 3 and a low NCCN-IPI risk was small.” In the Discussion, the fourth sentence fourth paragraph should read as follows: “This suggests that the value of PET in the detection of microscopically viable lymphoma in the BM at the end of treatment is limited.” Also, the fifth sentence fourth paragraph should read as follows: “In addition, in a retrospective study in 102 patients with extranodal NK/T-cell lymphoma investigating the prognostic value of the posttreatment Deauville score, Kim et al. found that a posttreatment Deauville score of 1 or 2 was significantly associated with better PFS and OS than a score of 3 or 4, and a score of 2 was determined as the cut-off score for predicting a complete metabolic response.” In the Discussion, third and fourth paragraphs were improperly separated and it should be merged into single paragraph for a continuous explanation.

The original article has been corrected.
