[Surgical indication for T1N2 disease: comparison of survival among resected T1N2, T2 N2 and non-resected T1 (M0) disease].
Based on the outcome of 28 patients with pathologically confirmed T1N2 disease who underwent surgical resection, we evaluated surgical indication for this stage. Twenty three patients underwent complete resection and 5 patients incomplete resection. The histologic type of tumor was adenocarcinoma in 20 patients and squamous cell carcinoma in 8 patients. The 5-year survival rate was 22% for all resected patients and 28% for completely resected patients. These survival rates were better than those (16% and 23%, respectively) in patients with T2N2 disease. However, there was no significant difference of survival among incompletely resected T1 N2, and non-resected T1 (M0) patients. Although 9 of 28 T1N2 patients survival more than 3 years, all but one patient underwent complete resection of tumor and had clinical N0 or N1 before surgery. In conclusion, surgery should be indicated only for patients with completely resectable tumor, even in T1N2 disease.
