BACKGROUND: The purpose of this study was to compare the prognosis of patients with T1 squamous cell carcinoma (SCC) with those with T1 adenocarcinoma of the esophagus and to explain prognostic differences by an analysis of clinicopathologic characteristics. METHODS: Seventy-seven patients with early esophageal cancer who underwent esophagectomy and lymphadenectomy from 1982 to 1993 were included in the study. Clinical and histopathologic characteristics, patterns of lymph node metastasis, results of surgery, and long term prognosis of 47 patients with SCC were compared with 30 patients with adenocarcinoma; a multivariate analysis of various prognostic factors was performed. RESULTS: The groups with adenocarcinoma and SCC were comparable regarding age, postoperative 90-day mortality (6.6% vs. 8.5%), infiltration of submucosa (74.5% vs. 80%), and rate of lymph node metastasis (17% vs. 16.6%). Cancer limited to the mucosa was not associated with lymph node metastasis in either group, whereas submucosal spread showed lymph node involvement in 21% of patients with adenocarcinoma and 26% of those with SCC. The 5-year survival rate of patients with complete tumor removal was superior for those with adenocarcinoma (82.5%) compared with those with SCC (59.2%) (P < 0.03). Multivariate analysis indicated that the histopathologic type (adenocarcinoma vs. SCC) was the only independent prognostic factor. The unfavorable prognosis of patients with T1 SCC was due to a higher recurrence rate and the more frequent development of second primary tumors (21% vs. 0%). CONCLUSIONS: The prognosis of patients with early esophageal cancer depends on the histologic tumor type. Patients with T1 SCC should be examined for another primary cancer before surgery and during follow-up.
