Programmed cell death is a combined intracellular process. For the activation of apoptosis as proapoptotic genes and antiapoptotic ones are needed as well. There are several methods of apoptosis assessment but in laryngeal cancer prognostic value of apoptotic index is still unclear. 44 patients with laryngeal cancer who received surgical treatment in ENT Department of Medical University of Lodz were analysed. Apoptotic index (AI) was studied by TUNEL assay (TdT-mediated dUTP nick and labeling). There were assessed correlation between AI and primary tumor size and nodal status based on TNM system; local and nodal recurrences; and survival rate after surgical treatment. We observed significant correlation between AI and degree of neoplastic cell polymorphism (p=0,043) and tumor size (T feature) (p=0,01). IA was also significantly correlated with epiglottic site of tumor (p=0,036). There were no correlation between IA and N or M features, local and nodal recurrences or survival rate. Based on these findings we conclude that apoptosis index can be a valuable in prognostic assessment of patients with laryngeal cancer.

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.
