Glottic cancer T4

OBJECTIVE: Laryngeal cancer is a common tumor in the head and neck, and surgery is one of the main treatment methods for laryngeal cancer. Laryngeal cancer surgery destroys the laryngeal cartilage scaffold, leading to structural changes in the laryngeal cavity and affecting respiratory compliance during sleep. However, less attention has been paid to the impact of changes in laryngeal structure on sleep breathing conditions. This article conducts a prospective study on the effects of preserving laryngeal function in cancer glottic surgery on sleep and respiratory status in patients, in order to understand the preoperative and postoperative OSAHS(obstructive sleep apnea-hypopnea syndrome) of glottic cancer patients , as well as the impact of surgery on OSAHS of patients...

OBJECTIVE: Survival of patients with advanced laryngeal squamous cell carcinoma (LSCC) remains poor and management protocols warrant further development. We thus investigated treatment and outcome-related factors for LSCC in Stockholm, Sweden. METHODS: In a retrospective setting, 520 patients with LSCC diagnosed during 2000-2014, were included. Data on stage, treatment, and outcome were correlated with recurrence-free and overall survival (RFS and OS, respectively)...

In advanced glottic cancer, it is widely known that definitive chemoradiation can result in comparable survival outcomes to primary surgery. This deserves consideration given the immense effects total laryngectomy (TL) has on patients. It is important to consider that not all advanced glottic tumors should be treated in the same way, and surgical management remains a critical consideration for optimization of local control and survival outcomes. Advances in organ preservation surgery and the more developed understanding of the survival benefits of TL in extensive T4 disease further support the importance of surgery in the management of advanced glottic cancer...

PURPOSE: Treatment decision-making in advanced-stage laryngeal squamous cell carcinoma (LSCC) is difficult due to the high recurrence rates and the desire to preserve laryngeal functions. New predictive markers for radiosensitivity are needed to facilitate treatment choices. In early stage glottic LSCC treated with primary radiotherapy, expression of hypoxia (HIF-1α and CA-IX) and proliferation (Ki-67) tumour markers showed prognostic value for local control. The objective of this study is to examine the prognostic value of tumour markers for hypoxia and proliferation on locoregional recurrent disease and disease-specific mortality in a well-defined cohort of patients with locally advanced LSCC treated with primary, curatively intended radiotherapy...

The applicability of the telomerase reverse transcriptase (TERT) gene Rs2736100 polymorphism in cancer research has been well documented for various malignancies except for head and neck cancers, where data is sparse. This study aimed to analyze this polymorphism with the pathological characterizers of laryngeal squamous cell carcinoma (LSCC) patients. Genetic testing was performed using the Real-time PCR technique on 56 paired samples of biological material (blood and tissue). Data were analyzed using Epi info 7 software...

According to mild, moderate and severe CSE1L staining, patients were compared in terms of disease-free survival, disease recurrence and development of distant metastases...

PURPOSE/OBJECTIVE(S): Treatments offering anatomic and functional preservation of the larynx are offered to most patients with laryngeal squamous cell carcinoma (L-SCC). However, upfront laryngectomy (Lgx) with pathology-guided adjuvant therapy is generally preferred for patients with T4 disease. Analyses of national care patterns and outcomes among T4 patients have raised concern that inappropriate use of larynx preservation (LP) is contributing to reduced survival as compared to Lgx-based approaches...
