Risk Factors for Feeding Tube Dependency in Patients Undergoing Function Preservation Surgery for Advanced-Stage Laryngohypopharyngeal Cancer.

Dysphagia and feeding tube dependency commonly occur in patients with laryngeal or hypopharyngeal cancer (LHC) during and after treatment, often leading to poor functional outcomes. Therefore, we examined the factors related to feeding tube dependency among advanced-stage LHC patients undergoing curative surgery. This study included 69 consecutive patients who underwent conservative surgery for previously untreated, advanced-stage LHC (squamous cell carcinoma) between 2006 and 2016. Persistent feeding tube dependency was defined as 1 year or more after treatment completion. Binary logistic regression analysis was used to determine the factors associated with reactive prolonged and persistent feeding tube dependency. Cox proportional hazard regression analysis was used to determine the association between feeding tube dependency and survival. None of the study patients had a prophylactic feeding tube, but 15 (21.7%) patients had reactive feeding tube placement for 3 months or more. A total of 9 (13.0%) patients had persistent feeding tube dependency. Univariate analysis showed that age, tracheostomy, and common terminology criteria for adverse events (CTCAE) ≥ 3 were significantly associated with reactive prolonged and persistent feeding tube dependency (all P < 0.05). In the multivariate analysis, advanced age and CTCAE ≥ 3 remained the independent factors of reactive prolonged and persistent feeding tube dependency (all P < 0.05). Feeding tube dependency was not associated with overall survival or disease-free survival (P > 0.1). Feeding tube dependency might be related to clinical factors, such as age and severe adverse events, in the patients undergoing function-preserving surgery for advanced-stage LHC.

Pediatric Laryngeal Granular Cell Tumor: Case Report and Literature Review.

Granular cell tumors (GCTs) are rare benign tumors that can occur in any part of the body. They are most commonly found in the head and neck region, especially the tongue. Laryngeal GCTs are rare, accounting for only 3% to 10% of all GCTs. This case report describes a 4-year-old boy with a laryngeal GCT. The patient presented with a history of hoarseness for 2 years. Stroboscopy revealed a large mass occupying the entire length of the left vocal cord. The mass was successfully removed by microlaryngeal surgery with laser ablation. The patient's symptoms resolved after surgery, and he had an uneventful recovery. This case highlights the importance of considering GCTs in the differential diagnosis of patients with hoarseness. Early diagnosis and treatment can lead to excellent outcomes.

Metastatic lymph node burden predictive of survival in patients undergoing primary surgery for laryngeal and hypopharyngeal cancer.

PURPOSE: Metastatic lymph node (LN) burden is one of the most important prognosticators in human solid cancers, but has rarely been examined in laryngeal and hypopharyngeal cancers (LHC). We evaluated the nodal factors predictive of recurrence and survival in patients with LHC. METHODS: This study included 141 consecutive patients who underwent primary surgery and neck dissection for previously untreated LHC at our tertiary referral centre. Nodal factors included the presence of pathological LN metastasis, number of positive LNs, LN ratio, and extra-nodal extension (ENE). Our proposed N classification was analysed by recursive partitioning analysis and compared with the AJCC and other N classifications using the c-index. Univariate and multivariate Cox proportional hazard regression analyses were used to define significant predictors of post-treatment disease-free survival (DFS) and overall survival (OS). RESULTS: Of the 141 patients, 66 (46.8%) had positive LNs, and 27 (19.1%) had ENE. In multivariate analyses, the number of positive LNs was strongly associated with DFS and OS outcomes (P < 0.01). Our new N classification was proposed with four categories, such as N0 (0 LN +), N1 (1 LN +), N2 (2-4 LN + or ENE) and N3 (≥ 5 LN +). The C-index of our new N classification improved the OS prediction (0.718) compared with the AJCC and the other N classifications (0.704-0.713). CONCLUSION: Metastatic LN burden is an important predictor of survival in patients with LHC. A proposed N classification using the number of positive LNs and ENE might improve the LHC survival prediction.
