Abstract

To predict occult nodal metastasis in clinical N0 patients with tongue cancer, we developed combined index (CI) : SUVmax of the largest lymph node in PET/CT by weighting coefficient plus its maximum minor axis (< 10 mm) in contrast-enhanced CT (CECT). In this retrospective study, 57 clinical N0 patients with tongue cancer, who underwent elective supraomohyoid neck dissection at cervical levels of I-III were enrolled. The cutoff value of SUVmax of 2.0 obtained using receiver operating characteristic (ROC) analysis predicted the postoperative positive cervical levels containing metastatic lymph nodes from clinical N0 cervical levels in tongue cancer patients with a sensitivity of 54.5% and a specificity of 78.2%. The cutoff value of CI with weighting coefficient of 1.5 obtained using ROC analysis was 9.8 at the maximum area under the curve of 0.750. The cutoff value of 9.8 predicted the postoperative positive cervical levels containing metastatic lymph nodes from clinical N0 cervical levels in tongue cancer patients with a sensitivity of 68.2% and a specificity of 81.5%. These findings suggest that CI of functional PET/CT and morphological CECT components might improve the diagnostic performance of occult nodal metastasis to select clinical N0 patients with tongue cancer preferable for elective neck dissection.

Abstract

Background and Aim Methods Results Conclusions Effective treatment of lesions that develop in the irradiated area of head and neck squamous cell carcinoma is a major concern. This study aimed to clarify the efficacy and safety of endoscopic resection for such lesions.Among consecutive patients who underwent endoscopic resection for histologically proven head and neck squamous cell carcinoma between January 2014 and December 2021, those who received definitive radiotherapy/chemoradiotherapy before endoscopic resection were included in this single‐center, retrospective study. Short‐ and long‐term outcomes were evaluated.Among 422 patients who underwent endoscopic resection for 615 lesions, 43 patients with 57 lesions were eligible. All 57 lesions were treated with endoscopic submucosal dissection and en bloc resection was achieved in all lesions. Grade 3 of Common Toxicity Criteria for Adverse Events v5.0 occurred in eight (19%) patients (dysphagia, seven; stricture, three; aspiration pneumonia, two; and pharyngeal necrosis, one [some cases overlapped]), but no grade ≥ 4 events occurred. Enteral nutrition by gastrostomy was temporarily required in two patients owing to dysphagia and laryngeal necrosis. During the median follow‐up of 40 (interquartile range, 29.5–61) months after endoscopic submucosal dissection for the lesions developed in the irradiated area, local recurrence and metachronous lesions developed in two (5%) and nine (21%) patients, respectively. However, total laryngectomies and tracheostomies were avoided in all patients. The 3‐year overall and disease‐specific survivals were 81% (95% confidence interval, 64%–91%) and 94% (95% confidence interval, 79%–99%), respectively.Favorable local control and safety of endoscopic submucosal dissection were demonstrated.
