Correction to: Ultrasound-guided resection for squamous cell carcinoma of the buccal mucosa: A feasibility study (Head & Neck, (2023), 45, 3, (647-657), 10.1002/hed.27281)

After publication, the authors noticed some minor errors. Please see the updates outlined here: On page 650 in section 2.4 Histology, “Margins at the craniolateral, caudomedial and deep parts of the specimen were measured digitally. The margins at the anterior and posterior parts were calculated by multiplying the number of tumor-free slices, determined by microscopic images, with the mean slice thickness.” should have read “Margins at the cranial, caudal and deep parts of the specimen were measured digitally. The margins at the anterior and posterior parts were measured digitally at the first or last slice containing tumor, respectively.” A switch up occurred with the ≥ and < symbols in the Results and Discussion sections. In the abstract on page 647, “The sensitivity to detect clear margins using ex-vivo ultrasound was low (48%).” should have read “The sensitivity to detect <5mm margins using ex-vivo ultrasound was low (48%).” On page 652 in section 3.2 Tumor-free margins, “Of the 29 < 5.0 mm tumor-free margins on histology, only 15 (52%) were correctly identified as <5.0 mm by the ex-vivo US.” should have read “Of the 29 < 5.0 mm tumor-free margins on histology, only 14 (48%) were correctly identified as <5.0 mm by the ex-vivo US.” “The area under the curve was 0.70 (95%CI: 0.56–0.84, p = 0.007) for ≥5.0 mm histological tumor-free margin, which was fair. The sensitivity of the ex-vivo US at 5.0 mm tumor-free margin was 48%, which means that the histological tumor-free margin was ≥5.0 mm in 48% of the ultrasound measurements that were ≥5.0 mm.” should have read “The area under the curve was 0.70 (95%CI: 0.56–0.84, p = 0.007) for <5.0 mm histological tumor-free margin, which was fair. The sensitivity of the ex-vivo US at 5.0 mm tumor-free margin was 48%, which means that in 48% of <5.0 mm histological margins, the ultrasound measured <5.0 mm.” This was also adjusted in Figure 4 and Table 3. Please see the corrected figure and table here: 4 FIGURE (Figure presented.) The ROC curve: margins measured on ex-vivo US for a < 5.0 mm histological tumor-free margin. The arrows indicate the sensitivity of the US at a certain tumor-free margin measured with the ex-vivo US. Abbreviations: US, ultrasound; ROC, receiver operator characteristics; mm, millimeter.

Table 3: Here the hypothetical results are shown if a tumor-free margin of <7.5 mm on the ex-vivo US would lead to a re-resection and the consequence for the histological tumor-free margin. Abbreviations: US = ultrasound, mm = millimeter. The authors apologize for these errors. The errors do not change the outcome of the study.
