Background: The outcome and prognostic factors of surgically resected pulmonary metastasis were analyzed to improve long term survival. Materials and
Methods: The organ and pathology of primary tumor, disease free interval (DFI), laterality, operative procedures, postoperative complications, therapeutic result, and prognostic factor were analyzed in 54 patients with surgically resected pulmonary metastasis at the Department of Thoracic ＆ Cardiovascular Surgery, Kosin Medical College between Jan. 1985 and Dec. 2002.
Results: The average age was 46 years old (8 to 70 years, 17 males and 7 females). The primary tumors were comprised of 39 cases of carcinoma(72%), 14 cases of sarcoma(26%), and Wilm’s tumor in 1 cases(2%). Among the carcinomas metastasized to the lungs. 10 cases(26%) were breast cancers, 8 cases(20%) were CRCs and renal cell carcinoma in 6 cases(15%). Osteosaroma in 4 cases(29%) was the most common sarcomas. The operative procedures in pulmonary metastasis were 70 cases for 54 patients: 40 cases(57%) in partial resection of lung, 21 cases(30%) in lobectomy, 4 cases(6%) inlobectomy with partial resection of lung, 1 cases(1%) in bilobectomy. 1 case (1%) in bilobectomy with partial resection of lung, 2 cases(3%) in pneumonectomy and 1 cases(1%) in only dissection of mediastinal lymph nodes. The average disease free interval was 26.5 months(1 month to 99 months). The 2-year survival rate (2YSR) was 2%(carcinoma 70%, sarcoma 34%) and carcinoma was higher than sarcoma in 2YSR (p=0.02).
Conclusion: The 2YSR of patients with surgically resected pulmonary metastasis was 62%. The 2YSR of patients with carcinoma was higher than sarcoma, but there was no difference between subgroups classified according to sex, laterality, DFI, operative procedure, number, and size of metastatic mass.
