Background and objective
Pulmonary metastasectomy is a standard therapy for some types of metastatic lesions in the lung. Although the prognosis for esophageal cancer patients with pulmonary metastasis is poor, it has been reported that some post-esophagectomy patients have good prognosis after pulmonary metastasectomy. We investigated the role of resecting pulmonary metastases arising from esophageal cancer at our institution.
Patients and methods
Seven patients with primary squamous cell carcinoma or adenocarcinoma of the thoracic esophagus who underwent resection of metachronous pulmonary metastases at our institution between 2006 and 2012 were identified from a retrospective database. All patients had undergone curative resection of their primary esophageal carcinoma.
Results
Six patients had unilateral and solitary lung metastasis. One patient presented with one metastatic lesion on each side, and he underwent 4 metastasectomy for pulmonary metastasis 3 times. There was no perioperative morbidity or mortality. The disease-free interval after esophagectomy ranged from 191 to 559 days (median, 463 days). Survival after pulmonary metastasectomy ranged from 357 to 3191 days (median, 1803 days). Three patients received systemic chemotherapy before metastasectomy. Currently, 5 patients are alive without evidence of recurrent disease.
Conclusion
Pulmonary metastasectomy may be acceptable as a part of multimodal treatment for solitary metachronous pulmonary metastasis in esophageal carcinoma.
