Clinical Analyse Relevant Factors Of The Metastasis Of Lymph Node Next To The Recurrent Laryngeal Nerve For91Cases Of Esophageal Cancer Resection By Three Incisions

Objectives：Based on pathology and clinical analysis of91cases by three incision inpatients with esophageal cancer resection, to explore the related factors influencingthe metastasis of lymph node next to the laryngeal recurrent nerve, so as to guide thechoice of the ways of esophageal cancer surgery.Methods：Collect91cases of esophageal resection by three incisions from January2013to February2014in the first Affiliated Hospital of Fujian Medical University,Thoracic Surgery, the group of professor Xu Li. According to the patients whether themetastasis of lymph node next to the laryngeal recurrent nerve or not can be dividedinto non-metastasis group (61cases) and metastasis group (n=30).Univariateanalysis used the Spearman rank correlation analysis, multivariate analysis usedBinary Logistic Regression, to look for risk factors of metastasis of lymph node nextto the laryngeal recurrent nerve.Results：(1)Resected lymph nodes was2479,27.4per capita；metastasis lymph nodeswas218,2.4per capita, lymph node metastasis rate was52.75%(48/91)。 Themetastasis rate of lymph node next to the laryngeal recurrent nerve rate was33.0%(30/91),in which metastasis rate of lymph node next to the left laryngeal recurrentnerve was l6.48%(15/91), and the metastasis rate of lymph node next to the rightlaryngeal recurrent nerve was24.18%(22/91).(2).The Spearman rank correlation analysis:The metastasis of lymph node next to thelaryngeal recurrent nerve has presence correlation with gender、degree of differentia--tion、 depth of invasion and stage (P <0.05)， has no significant correlation withhistological type,、 tumor location、 the number of metastatic lymph nodes and thenumber of lymph node dissection (P>0.05).(3).The Binary Logistic Regression method：Put the "gender, histological type, degree of differentiation, tumor location, depth of invasion,stage, number of metastaticlymph nodes, number of lymph node dissection" into the regression equation,afterstepwise regression we find that：the OR of sex is7.566,P<0.05；the OR of stage is1.820,P<0.05。Male is easier to appear metastasis of lymph node next to the laryngealrecurrent nerve than female; The later stage,the easier it is to appear metastasis oflymph node next to the laryngeal recurrent nerve.Conclusion: The metastasis of lymph node next to the laryngeal recurrent nerve haspresence correlation with gender、 degree of differentiation、 depth of invasion andstage;"Sex and stage" are independent risk factors for the metastasis of lymph nodenext to the laryngeal recurrent nerve.
