Discordant Responses Between Imaging Examination and Surgical Pathology of Head and Heck Squamous Cell Carcinoma After Neoadjuvant Immunotherapy Combined With Chemotherapy.
World J Oncol
February 2025
Department of Head and Neck Surgery, National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China.
Background: We here investigated the value of imaging examination in evaluating tumor remission-based surgery in patients with head and neck squamous cell carcinoma (HNSCC), who had undergone neoadjuvant immunotherapy combined with chemotherapy (NICC).
Methods: HNSCC patients who underwent NICC and surgery from May 2021 to September 2023 were retrospectively analyzed. All patients had to undergo imaging examination evaluation, including enhanced computed tomography (CT) and enhanced magnetic resonance (MR) imaging before and after NICC.
Use of Intraoperative Frozen Section to Assess Surgical Margins in HPV-Related Oropharyngeal Carcinoma.
JAMA Otolaryngol Head Neck Surg
January 2025
Department of Otolaryngology/Head and Neck Surgery, Washington University in St Louis School of Medicine, St Louis, Missouri.
Importance: Given the favorable overall prognosis of human papillomavirus (HPV)-related oropharyngeal squamous cell carcinoma (OPSCC) and the morbidity of increased adjuvant therapy associated with positive surgical margins, large-scale studies on the accuracy of frozen sections in predicting final surgical margin status in HPV-related OPSCC are imperative. Final surgical margin status is the definitive assessment of tumor clearance as determined through surgeon-pathologist collaboration based on permanent analysis of frozen section margins, main specimens, and supplemental resections.
Objectives: To assess the accuracy and testing properties of intraoperative frozen section histology (IFSH) in assessing final surgical margin status in patients undergoing transoral surgery for HPV-related OPSCC.
[Evaluation of pharyngeal and laryngeal squamous cell carcinoma after neoadjuvant immunochemotherapy by narrow band imaging].
Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi
January 2025
Department of Otolaryngology-Head and Neck Surgery, the First Affiliated Hospital of Xiamen University, School of Medicine, Xiamen University(Teaching Hospital of Fujian Medical University), Xiamen361003, China Xiamen Key Laboratory of Otolaryngology Head and Neck Surgery, Xiamen361003, China.
To investigate the changes in the narrow band imaging (NBI) phenotypes of oropharyngeal, hypopharyngeal, and laryngeal squamous cell carcinoma after neoadjuvant immunochemotherapy, and to explore the clinical value of NBI endoscopy in re-evaluation and follow-up of pharyngeal and laryngeal squamous cell carcinoma after neoadjuvant immunochemotherapy. Twenty-nine patients diagnosed with locally advanced pharyngeal or laryngeal squamous cell carcinoma in the First Affiliated Hospital of Xiamen University from November 2021 to January 2024 and receiving 2 cycles of neoadjuvant immunochemotherapy were selected, including 26 males and 3 females, aged 43-80 years. Regular NBI and white light (WL) endoscopy examinations, as well as imaging examinations such as CT scans, were performed.

Oral Oncol
January 2025
Department of Otorhinolaryngology, Head and Neck Surgery, Chang Gung Memorial Hospital and Chang Gung University, Taoyuan, Taiwan, ROC. Electronic address:
Background: The question as to whether prolonged diagnosis-to-surgery intervals (DSIs) may compromise survival outcomes in patients with oral cavity squamous cell carcinoma (OCSCC) remains unanswered. This nationwide study was designed to address this issue.
Methods: We analyzed data from 26,214 patients with first primary OCSCC identified in the Taiwanese Cancer Registry Database between 2011 and 2021.
Purpose: Radiotherapy (RT)/cetuximab (C) demonstrated superiority over RT alone for locally advanced squamous head and neck cancer. We tested this in completely resected, intermediate-risk cancer.
Methods: Patients had squamous cell carcinoma of the head and neck (SCCHN) of the oral cavity, oropharynx, or larynx, with one or more risk factors warranting postoperative RT.
