Background: This study aimed to evaluate the effect of TrkB down-regulation on the malignant biological behavior and stem-like characteristics of laryngeal cancer.
Methods: The relationship was analyzed between TrkB and clinicopathological parameters in patients with laryngeal cancer. The mRNA expressive levels of TrkB and miR-10a-5p were detected by qRT-PCR in laryngeal cancer tissues and cell lines. In vitro, Hep-2 and AMC-HN-8 cell proliferation, apoptosis and stem-like properties were detected by colony formation assay, flow cytometry, sphere formation, and Western blot, respectively. In vivo, the BALB/c nude mice model was used to evaluate the effect of TrkB on tumor growth.
Results: The results showed that TrkB was related to smoking history, clinical stage, and lymph node metastasis, but had nothing to do with the gender, age, and tumor location of patients with laryngeal cancer. TrkB was highly expressed and miR-10a-5p was lowly expressed in laryngeal cancer tissues and cell lines. Down-regulation of TrkB inhibited Hep-2 and AMC-HN-8 cell proliferation and sphere formation as well as enhanced apoptosis, The result showed that miR-10a-5p bound to the 3'-UTR of BDNF by a dual-luciferase reporter assay. Down-regulation of miR-10a-5p induced up-regulation of TrkB promoting development of laryngeal cancer. In vivo, down-regulation of TrkB suppressed tumor growth and inhibited the expression of stem-like marker proteins and promoted apoptosis.
Conclusion: In conclusion, down-regulation of TrkB plays an important role in laryngeal cancer and is a promising target for future intervention strategies.

Background: The advanced stage of cancer is a determining factor in poor prognosis. Head and neck squamous cell carcinomas (HNSCC) are highly incident in Brazil, but similarly to many Low and Middle-Income Countries, data is limited regarding the proportion of tumours diagnosed at advanced clinical stages and the main factors associated with it. Therefore, this study aimed to identify the factors associated with advanced stage of HNSCC in Brazil.

Objective: This study aimed to clarify whether nutritional status at admission affects enteral nutrition weaning 6 months after surgery in patients with esophageal cancer.
Methods: This was a retrospective study of 81 patients who underwent subtotal esophageal cancer resection between April 2014 and February 2016. The survey items were as follows: 1) sex, 2) age, 3) presence or absence of family members living together, 4) clinical stage, 5) surgical procedure, 6) reconstructed organs, 7) nutritional status at admission, 8) presence or absence of postoperative complications (anastomotic leakage, chylothorax, and recurrent laryngeal nerve paralysis), and 9) presence or absence of treatment other than surgery (chemo- or radiotherapy).

Background: Airway obstruction secondary to chyle leak is an exceptionally rare phenomenon. Here, we describe this complication in a patient with anaplastic thyroid carcinoma (ATC) undergoing consolidative surgery after BRAF-targeted therapy.
Methods: A 55-year-old man presented with a rapidly enlarging neck mass.

Objective: TRIB3 has been confirmed to participate in and regulate biological metabolic activities in head and neck tumors such as nasopharyngeal carcinoma and oropharyngeal carcinoma, so the purpose of this study was to explore whether there is a correlation between TRIB3 and Laryngeal Squamous Cell Carcinoma (LSCC) and to preliminarily explore the biological characteristics of TRIB3 in LSCC.
Methods: TRIB3 expression in the LSCC was analyzed based on The Cancer Genome Atlas (TCGA) database. CCK-8 assay, Colony Formation Assay, wound healing assay, and Transwell assay were performed to investigate the roles of TRIB3 in the proliferation, invasion and metastasis of LSCC.

Background And Objectives: Recent advances in multimodal large language models (MLLMs) have shown promise in medical image interpretation, yet their utility in surgical contexts remains unexplored. This study evaluates six MLLMs' performance in interpreting diverse imaging modalities for laryngeal cancer surgery.
Methods: We analyzed 169 images (X-rays, CT scans, laryngoscopy, and pathology findings) from 50 patients using six state-of-the-art MLLMs.
