Objectives: LMNA-associated familial partial lipodystrophy (FPLD) is a rare autosomal dominant A-type laminopathy characterized by variable loss and redistribution of subcutaneous adipose tissue, dyslipidemia, and insulin resistance. Though A-type lamins play a key role in nuclear membrane structure and regulation of cell proliferation, an association between cancer and LMNA-associated FPLD has not been reported.
Methods And Results: This report outlines the case of two biological sisters with LMNA-associated FPLD who developed hypopharyngeal squamous cell carcinoma in the absence of any other risk factors for head and neck cancer.
Conclusion: These observations prompt further investigation into the potential role of A-type lamins in the development and progression of head and neck cancers.

Purpose: Cancer stem cells (CSCs) are considered key drivers of progression in head and neck squamous cell carcinoma (HNSCC). Our single-cell RNA sequencing (scRNA-seq) analysis revealed predominant expression of CD271 in CSCs, however, its role as a CSC marker in HNSCC requires further elucidation. We investigated the stemness characteristics of CD271 HNSCC cells and their interactions with the tumor immune microenvironment.

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.

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.

Objective: To assess the efficacy of computed tomography (CT)-based radiomics nomogram in predicting perineural invasion (PNI) in patients with hypopharyngeal squamous cell carcinoma (HPSCC).
Materials And Methods: Overall, 146 patients were retrospectively recruited and divided into training and test cohorts at a 7:3 ratio. Radiomics features were extracted and delta and absolute delta radiomics features were calculated.
