ABSTRACT
Objective@#To compare the treatment outcomes for locally advanced hypopharyngeal carcinoma between surgery plus radio(chemo) therapy(SRT) and non-surgery chemoradiotherapy(CRT).@*Methods@#A total of 119 patients diagnosed with advanced hypopharyngeal carcinoma without distant metastases between 2010 and 2014 were identified in the Chinese People′s Liberation Army General Hospital, and they were divided into 2 groups: 42 cases in SRT group and 77 cases in CRT group. Patients′ clinical information was collected. Survival rates and prognostic factors were analyzed by the Kaplan-Meier method with SPSS 23.0 software. The survival rates, laryngeal preservation rates and complication rates were compared between the two groups using the chi-square test.Among the 119 patients, 112 were males and 7 were females. Age ranged from 27 to 78 years, with an average age of 57 years.@*Results@#There were no significant difference between the SRT and CRT group for five-year disease-free survival (DFS, 53.9% vs. 45.1%, χ2=1.251, P=0.263) and overall survival (OS, 54.9% vs. 45.6%, χ2=1.749, P=0.186). Compared to SRT group, CRT group did not showed the significant increase of treatment complications (χ2=0.858, P=0.354), with a higher laryngeal preservation rate (50.0% vs. 71.4%, χ2=6.493, P=0.011).@*Conclusions@#Advanced hypopharyngeal carcinoma is of high malignancy and poor prognosis. Combined modality treatment is a main approach for advanced hypopharyngeal cancer. SRT offers disease-free survival and overall survival rates equivalent to CRT, but with a higher laryngeal preservation rate.
ABSTRACT
OBJECTIVE To explore the difference of vestibular damage between sudden deafness and vestibular neuritis.METHODS Patients in otolaryngology head and neck surgery eenterin PLA general hospital from February 25 in 2016 to July 20 in 2016 were included in this research.Among these patients,55 cases were diagnosed as sudden deafness group,including 39 cases With vertigo.And other 46 cases were diagnosed as vestibular neuritis.Vestibular bithermal caloric test,head impulse test(head impulse test,HIT),cervical vestibular evoked myogenic potentials(cervical vestibular evoked myogenic potential,cVEMP),ocular vestibular evoked myogenic potentials(ocular vestibular evoked myogenic potential,oVEMP) were performed to evaluate their vestibular function and were compared.RESULTS The abnormal rate of vestibular bithermal caloric test in sudden deafness group 25.45％,and 97.82％ in vestibular neuritis group.There was significant difference between two groups(x2=54.01,P＜0.001).HIT:the abnormal ratein sudden deafness groupwas 9.09％ and 32.61％ in vestibular neuritis group,there was significant difference between two groups(x2=8.72,P=0.003).VEMP:the abnormal rate of cVEMP in sudden deafness group was 69.10％ and 43.47％ in vestibular neuritis group,there was significant difference between two groups(x2=6.72,P=0.010).But the abnormal rate of oVEMP in sudden deafness group was 54.55％ and 63.04％ in vestibular neuritis group,and there was not statistically significant difference between two groups(x2=0.745,P=0.388).CONCLUSION The vestibular damage of sudden deafness with vertigo was more likely involved with saccule and inferior vestibular nerve,more close to the nerve terminal,and the injury was in a low frequency range;but the vestibular damage in vestibular neuritis was wider,and the injury involved a full band,the damaged part may be higher.
