ABSTRACT
Objective: In this study, we aimed to evaluate the effects of demographic data and comorbid diseases on the prognosis and treatment diagnosed with laryngeal squamous cell cancer (LSCC). Methods: Medical records of LSCC patients treated and followed up in a single referral center between 2008 and 2019 were retrospectively reviewed. In addition to the demographic data, the results of overall survival (OS), disease-specific survival (DSS), disease-free survival (DFS), locoregional-free survival (LRFS), and factors affecting recurrence were analyzed. Results: We included 573 patients with a mean age of 60.1±9.8 years. Of the 573 patients, 94.2% (540) were men, 93.7% (537) were smokers, 40.1% had at least one comorbid disease, and 69.8% (400) presented with glottic LSCC. The five-year OS, DSS, DFS, and LRFS rates for all cases were 65.7%, 79.9%, 67%, and 74.7%, respectively. In early-stage LSCC treatment, the rates of OS (p=0.008), DFS (p=0.024) and LRFS (p=0.01) were statistically significantly higher in the endolaryngeal laser surgery (ELS) group compared with the radiotherapy (RT) group. In advanced-stage LSCC treatment, total laryngectomy had statistically significantly higher five-year DFS (p=0.003) and LRFS (p=0.002) rates compared to chemoradiotherapy. Conclusion: Our study showed that ELS provided higher rates of OS, DFS, and LRFS compared to RT in the treatment of early-stage LSCC. Recurrence was significantly higher in supraglottic tumors, advanced-stage tumors, and in patients with clinical N positivity.
ABSTRACT
Objective: To investigate the prognostic value of the magnetic resonance imaging in Bell's palsy patients. Methods: Patients who were diagnosed and treated with Bell's palsy between October 2013 and March 2016 retrospectively selected. House-Brackmann grades, pre- and post-treatment pure tone audiograms, stapedial reflexes were analyzed and magnetic resonance imaging (MRI) scans with gadolinium-based contrast agents were evaluated. Contrast-enhanced segments of the facial nerve were determined. MRI findings were compared statistically with pre- and post-treatment grade, recurrence rate of Bell's palsy, MRI scanning timing, presence of stapes reflexes and posttreatment recovery data. Results: No significant correlation was observed between pretreatment House-Brackmann grades and enhancement (p>0.05). Similarly, there was no significant correlation between clinical recovery and enhancement (p>0.05). Also, no significant correlation was observed between MRI scanning time, the recurrence rate of Bell's palsy and MRI findings (p>0.05). None of the MRIs showed neoplastic contrast enhancement. Conclusion: The routine use of the contrast-enhanced temporal MRI is not recommended in the diagnosis and monitoring of Bell's palsy patients, because the contrast enhancement pattern of the facial nerve has no effect on the prognosis of Bell's palsy. MRI should be used in cases that do not heal despite treatment, for the differential diagnosis of facial nerve tumors and in patients who are candidates for surgical decompression.
