Abstract
Background: Adrenocortical carcinoma (ACC) is a rare tumor and the role of lymph node dissection remains ill-defined. This study evaluates the effect of nodal examination on prognosis and survival in patients undergoing curative-intent resection of ACC. Methods: The National Cancer Database (2004-2015) was queried for patients undergoing margin-negative resection for ACC. Patients with distant metastases, neoadjuvant therapy, multivisceral resection and T4 tumors were excluded. Results: Among 897 patients, 147 (16.4%) had lymph nodes examined. Factors associated with lymph node examination included increasing tumor size (P <.001), extra-adrenal extension (P <.001), open operation (P <.001), and resection at an academic facility (P =.003). Lymph node metastasis was significantly associated with extra-adrenal tumor extension (P =.04). Lymph node harvest, regardless of the number of nodes examined, was not associated with a survival benefit. Median overall survival was incrementally worse with increasing number of positive lymph nodes (88.2 months for N0, 34.9 months for 1-3 positive nodes, and 15.6 months for ≥4 positive nodes, P <.001). Conclusions: Lymph node harvest and lymph node metastasis were associated with more advanced tumors. Although nodal harvest did not offer a survival advantage, stratifying the nodal staging classification may provide important prognostic information.
