Factors predicting occult lymph node metastasis in completely resected lung adenocarcinoma of 3 cm or smaller

Abstract

The presence of micropapillary or solid pattern, as well as micropapillary/solid predominant pattern, is significantly associated with occult N2 lymph node metastasis in lung adenocarcinoma. Radical mediastinal lymph node dissection may help to identify occult lymph node metastasis in these patients.
