Surgical resection for oral tongue cancer pulmonary metastases

Abstract

The aim of this study was to evaluate the efficacy of surgical resection of oral tongue cancer (OTC) pulmonary metastases. Between 1977 and 2003, 23 OTC patients who developed 1-3 pulmonary metastases underwent metastasectomy. There were 14 men and nine women with a median age at the time of first metastasectomy of 56 years. All patients had advanced squamous cell OTC with synchronous or metachronous regional lymph node metastases. The median tumor-free interval after the last OTC treatment was 12 months. Five patients underwent pneumonectomy, three bilobectomy, 13 lobectomy, and two wedge resection. Two patients underwent a second pulmonary metastasectomy. One patient continues to survive, without recurrence 19 years after metastasectomy. Another patient was alive with disease at 24 months after metastasectomy but was lost to follow-up. Twenty-two out of 23 patients developed systemic metastases. The median interval to systemic recurrence after lung resection was 4.1 months, and 21 out of 23 patients died of OTC (median, 9.5 months) after metastasectomy. Most patients who underwent pulmonary metastasectomy died of the disease within two years of metastasectomy. Even for patients with a solitary metastasis, surgical metastasectomy is not a recommended treatment option.
