Abstract
BACKGROUND: Pulmonary metastasectomy is an established treatment modality for patients with soft as well as bone tissue sarcomas. Aim of this study is to describe the Essen experience in the surgical management of patients with pulmonary sarcoma metastases. METHODS: This is a retrospective single center analysis of perioperative outcome of patients undergoing pulmonary metastasectomy for sarcoma metastases from 1997-2017 and a summary of published papers on this topic. RESULTS: During the observation period 327 patients (49.23% female) underwent pulmonary metastasectomy for metastases of extrathoracic sarcomas in curative intent. The number of resected metastases was 1-3 in 283 cases (86.54%), 4-9 in 31 cases (9.48%) and 10 or more lesions in 14 cases (4.28%). Wedge resections or precision excisions with laser or electrocautery were performed in 278 cases (85.02%), anatomical segmental resections in 16 patients (4.89%) and lobectomies in 33 patients (10.09%). Bilateral procedures were performed in 98 cases (29.96%). Lymphadenectomy was performed in 122 patients. Positive lymph nodes were found only in 6 cases. All of these cases were patients with soft tissue sarcoma as primary tumor. Preoperative neoadjuvant treatment was performed in 79 patients (24.15%) with chemotherapy, in 54 patients (16.51%) with radiochemotherapy and in 10 patients (3.05%) with radiotherapy. Major postoperative complications were observed in 2.75% of all patients. Thirty-day mortality was 0%. CONCLUSIONS: Pulmonary metastasectomy in sarcoma patients is a feasible and safe treatment strategy even in patients with bilateral metastases and multiple lesions. Thoracic lymph node metastases are rare and did not influence survival in our cohort.
