Clinic features and prognostic analysis for T1 esophagus cancer / 中华肿瘤杂志

ABSTRACT

Objective@#To investigate relationship between the clinicopathological features and prognosis of T1 esophageal carcinoma.@*Methods@#Data from 212 T1 primary esophageal cancer patients, who underwent radical surgery in The Fourth Hospital of Hebei Medical University from Jan 2001 to Dec 2009 were enrolled. There were 148 males and 64 females. There were 91 patients with stage pT1a and 121 patients with stage pT1b.@*Results@#The survival of the 212 patients was 27~108 months, and the median survival was 80.8 months. The 1, 3, and 5 year survival rates of patients with stage T1a were 100%, 97.8% and 94.5%, respectively, and the median survival was 86.8 months. The 1, 3, and 5 year survival rates of patients with stage T1b were 100%, 95.9% and 74.4%, respectively, and the median survival was 76.2 months. The rate of lymph node metastasis in 121 patients with stage T1b was 26.4% (32/121). The lymph node metastasis rates in patients with stage sm1, sm2 and sm3 were 11.6% (3/26), 15.0% (6/40) and 41.8% (23/55), respectively. There was no significant difference in lymph node metastasis between stage sm1 patients and stage sm2 patients (P=0.973). Lymph node metastasis rates in patients with stage sm3 were higher than those in stage sm1 and sm2 (P<0.05).@*Conclusion@#Radical resection of esophageal carcinoma with peripheral lymph node dissection is recommended for patients with T1b esophageal carcinoma.
