Background: Salvage surgery for laryngeal cancer recurring after radiotherapy is difficult and complications readily occur. Our institution has adopted the pharyngeal interposition graft (PIG) using a pectoralis major myocutaneous (PMMC) flap, which has copious blood flow, for preventing post-irradiation pharyngocutaneous fistula.
Aims/objectives: The purpose of this study was to examine the incidence of post-operative complications of salvage total laryngectomy (STL) using the PMMC flap for post-radiotherapy recurrent laryngeal cancer at our institution.
Material And Methods: From among 162 patients with laryngeal cancer who had been treated at Tokyo Medical University Hospital between January 2014 and March 2018, we enrolled 11 patients who had undergone STL applying a PMMC flap. We examined patient backgrounds (age, gender, subtype, stage), initial therapy (radiotherapy/chemoradiotherapy), radiation dose, irradiation area, surgery type (with/without neck dissection) and postoperative complications.
Results: No severe systemic complications were encountered. Pharyngocutaneous fistula occurred as a severe local complication in one patient (8.3%) and wound infection as a mild local complication in one patient (8.3%).
Conclusions: Rates of post-operative complications following STL tended to be lower at our institution than those reported for other institutions.
Significance: PIG may be a useful surgical procedure in STL.

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.
