Carotid arterial blowout after organ preserving chemoradiation therapy in hypopharyngeal cancer.

Laryngeal preserving concurrent chemoradiation has been advocated for hypopharyngeal cancers. The use of radiotherapy (RT) in the larynx could lead to increased rates of radionecrosis. In this study, we investigated a rare but disastrous complication, carotid blow-out syndrome (CBS), related with the persistent radionecrosis. Retrospective cohort study. This retrospective study enrolled hypopharyngeal cancer patients with biopsy-proven pharyngeal and laryngeal chondronecrosis (PLCRN), which was rated by the Chandler Grading System. From 2002 to 2018, a total of 346 hypopharygeal cancer patients received upfront radiation therapy, 13 PLCRN patients were identified in a rate of 3.8%. All PLRN patients received RT with a mean radiation dose of 70.81 ±â€…0.85 Gy. All patients had Chandler Grade IV at the time of presentation, which was a mean of 15.08 months (range: 5-109 months) from the time of cancer diagnosis to PLCRN diagnosis. In 5 of the 13 PLCRN patients developed CBS. Three of the CBS originated from superior thyroid artery, one from lingual artery and one from the carotid artery. Three (60%) of the 5 CBS patients expired due to loss of airway and hemodynamic instability. Two (40%) were rescued by emergent airway secure and emergent angiographic embolization. Persistent PLCRN could lead to disastrous vascular complications. CBSs were demonstrated to be more frequently originated from the branches of carotid artery rather than carotid artery per se. Clinical alert with early airway protection could strive for time to do interventions and prevent mortalities.

Familial Aggregation of Head and Neck Cancer in Taiwan.

OBJECTIVES: Head and neck cancer (HNC) incidence has been increasing worldwide. We investigated the familial aggregation of developing HNC if a first-degree relative (FDR) is affected in a large database. METHODS: This retrospective study utilized Taiwan National Health Insurance Database to assemble a cohort of all registered beneficiaries from 1997 to 2013 and identified diagnosed HNC patients with affected FDRs. RESULTS: Of the 55,916 individuals diagnosed with HNC, 566 (1.01%) had affected FDRs. There were 525 (0.56%) males and 41 (0.05%) females. Age of onset of HNC was found to be earlier for those with an affected FDR at the fourth decade of life compared to the general population. The adjusted relative risks (RRs) of an individual with an affected FDR to develop HNC is 2.04 (95% confidence interval [CI], 1.85-2.26): 2.07 (95% CI, 1.88-2.29) if the affected relative was male, and 1.74 (95% CI, 1.31-2.30) if the affected relative was female. The greatest risk to develop HNC is if the affected individual is a twin with adjusted RR 33.04 (95% CI, 12.89-84.69). This is followed by an affected sibling at RR (95% CI) 3.46 (1.68-7.13), offspring at RR 2.28 (95% CI, 1.94-2.69), and parent at RR 1.66 (95% CI, 1.48-1.87). CONCLUSION: Familial tendency of HNC proves the probable contribution of genetic factors to develop cancer. In areca quid endemic region, there is a high likelihood that both environmental and genetic factors work in synergy to develop HNC. LEVEL OF EVIDENCE: 3 Laryngoscope, 131:806-812, 2021.

Influence of Hyperglycemia on Treatment Outcomes of Oral Cavity Squamous Cell Carcinoma.

PURPOSE: The present study investigated the association between perioperative hyperglycemia and the treatment and survival outcomes of patients with oral cavity squamous cell carcinoma (OSCC). PATIENTS AND METHODS: From 2004 to 2016, 385 patients with OSCC were enrolled and stratified into normoglycemic (<180 mg/dL) and hyperglycemic (≥180 mg/dL) groups. The clinicopathologic characteristics and treatment outcomes of OSCC were subsequently analyzed. RESULTS: Of the 385 patients, 61 (15.8%) were in the hyperglycemic group. Hyperglycemia was significantly associated with pT stage, pN stage, overall pathologic stage, extranodal extension, albumin level, and tumor depth (P = .004, P = .042, P = .008, P = .001, P = .004, and P = .011, respectively). Patients with hyperglycemia also required a longer hospital stay (P = .003). The 5-year overall survival and disease-specific survival were poorer in the hyperglycemic group than in the normoglycemic group (P = .001 and P = .002, respectively). Multivariate analysis revealed that hyperglycemia is a significant adverse prognostic indicator for OSCC (hazard ratio, 1.709; 95% confidence interval, 1.003 to 2.912; P = .049). CONCLUSIONS: Hyperglycemia is associated with more advanced disease and poorer survival rates in patients with OSCC. It correlates with adverse clinicopathologic characteristics and longer hospital stay. Screening for hyperglycemia and maintenance of normal glycemic status during the treatment course is imperative in the treatment of OSCC.

Relapsing polychondritis initially presenting with hoarseness and difficulty breathing in a 21-year-old male

@#<p style="text-align: justify;"><strong>OBJECTIVE:</strong> To present a case of relapsing polychondritis initially presenting with hoarseness and difficulty breathing and to discuss the diagnostic criteria and typical CT scan findings of relapsing polychondritis. <br /><strong>METHODS:</strong> <br /><strong>Design:</strong> Case Report<br /><strong>Setting:</strong> Tertiary Private Hospital in Metro Manila<br /><strong>Patient:</strong> One<br /><strong>RESULT:</strong> A 21-year-old man who was initially managed as a case of bronchial asthma for persistent hoarseness and recurrent difficulty breathing was found to have severe laryngeal edema on endoscopy, and soft tissue expansion of the cricoid cartilage with calcifications and irregular first tracheal ring on CT scan. He also had recurrent eye redness and developed bilateral aural inflammation, and was subsequently diagnosed to have relapsing polychondritis.<br /><strong>CONCLUSION:</strong> Relapsing polychondritis is a rare autoimmune disease characterized by recurrent inflammation and eventual destruction of cartilage throughout the body. Typical manifestations may not always be present, causing a delay in diagnosis. It should be considered in patients with intractable respiratory symptoms not responsive to treatment for upper respiratory tract infections or asthma. A CT scan may reveal signs of cartilage destruction and help in diagnosis.                  </p>
