Abstract:
Objective To explore the outcomes and prognostic effects of Ivor Lewis esophagectomy and evalue the N staging.Methods Participants comprised 1145 patients with ESCC from Jan.2004 to Dec.2013,who under-went Ivor Lewis esophagectomy.The clinicopathologic data were analyzed.Kaplan -Meier and Cox regression methods were used for survival analysis.Results The morbidity of postoperative complication was 9.15% and with 1.83% of motality.The 1 -,3 - and 5 -year survival rates were 84.2%,58.4%,47.9% respectively.The median survival time was 55 months and average survival time was (70.16 ±2.086)months.Cox model multivariate analysis was used for those of P <0.05 in single variate analysis.Univariate analysis revealed that gender(P =0.003),smoking history (P =0.013),alcohol history(P =0.017),tumor location(P =0.001),body mass index(P =0.008),tumor length (P =0.000),differentiation degree(P =0.000),numbers of metastic zones(P =0.000)of lymph node metastasis (P =0.000),depth of invasion (P =0.000),pathological staging(P =0.000),vascular tumor thrombus (P =0.000),nerve involvement(P =0.000)and postoperative adjuvant therapy(P =0.000)were influencing prognosis factors.And multivariate analysis revealed that differentiation degree(P =0.000),depth of invasion(P =0.000), numbers of metastic zones (P =0.013 )of lymph node metastasis (P =0.000)were independent risk factors. Conclusion Ivor Lewis esophagectomy was a safe and effective treatment,and tumor differentiation degree,depth of invasion,numbers and zones of lymph node metastasis were important prognostic factors.
