    Background
    

    Oral cancer often performs local recurrence or a neck lymph node metastasis, so pulmonary metastasis from oral cancer is very rare and there have been few reports.. The aim of this study was to evaluate the efficacy of surgical resection of oral cancer pulmonary metastases.

    Between April 2006 and December 2017, 14 patients with oral cancer pulmonary metastases underwent thoracic operations. We considered their clinicopathological features and prognosis.

    There were ten men and four women with median age of 66.5 years (range, 27-76). All tumors were squamous cell carcinoma. Primary sites were tongue (seven patients), gum (three patients), and the mouth bottom (two patients). Five patients had partial resection and nine patients underwent lobectomy or larger operation. Eight of the nine patients who had lobectomy also had systematic lymph node dissection. Overall survival rate after metastasectomy was 46.9% at five years. Overall survival rate at five years by lobectomy with systematic lymph node dissection tended to have a better prognosis than by partial resection or lobectomy without lymph node dissection(p=0.08). Among the patients who had systematic lymph node dissection, lymph node metastasis were found in five patients. However, three of the five got long-term survival (more than two years) in spite of the metastasis.

    For patients with oral cancer pulmonary metastasis, surgical resection especially lobectomy with lymph node desection is recommended.
