    Abstract:
    BACKGROUND & OBJECTIVE: Few research of surgery for superior mediastinal metastasis from thyroid carcinoma has been reported. Previous surgical approach from neck had the problems of easy damage of nerve and vessels and the difficulty of clearance of lymph nodes. This study was designed to assess the value of systemic superior mediastinal lymph node dissection via sternotomy for superior mediastinal metastasis from differentiated thyroid carcinoma. METHOD: A retrospective study was performed to analyze the clinical pathologic data as well as the outcome of 12 cases of differentiated thyroid carcinoma treated with systemic superior mediastinal lymph node dissection via sternotomy approach from April 1995 to April 2002, including 7 cases of papillary adenocarcinoma and 5 cases of medullary carcinoma. RESULTS: Pathologically, the incidence rates of metastasis to anteriotracheal lymph node, paratracheal lymph node, anterior superior vena cava, and anterior innominate artery lymph nodes were 55.6% (25/45), 57.1% (36/63), 42.1% (8/19) and 30% (3/10), respectively. All cases are still alive in one to seven years follow-up period. The median follow-up was 32 months. Upper mediastinal lymph nodes were recurrent in one case; distant metastasis occurred in two cases. CONCLUSION: Systemic superior mediastinal lymph node dissection via sternotomy approach can be employed in treating superior mediastinal lymph node metastasis from differentiated thyroid carcinoma due to its safety and relatively satisfactory outcome.
