THE SURGICAL-TREATMENT OF METASTATIC TUMORS IN THE LUNG - IS LOBECTOMY WITH MEDIASTINAL LYMPH-NODE DISSECTION SUITABLE TREATMENT

From January 1981 through October 1995, a total of 28 patients underwe nt surgery for metastatic lung tumors in our institute. A retrospectiv e review and survival analysis of these patients are reported. There w ere 12 males and 16 females, with the mean age of 57 years. Of them, 2 0 patients had solitary lesions. Pulmonary metastasis was from the col on in 8 patients, from the breast in 5, from the stomach and the uteru s in each 3, from the bladder, the rectum and the soft tissue in each 2, and from the kidney, the ovarium and the thyroid in each 1. A lobec tomy was performed in 22 patients, 17 of whom were accompanied with me diastinal lymph node dissection (R2a). Partial resection without lymph node dissection was performed in 6 patients (R0). Overall 5-year surv ival was 24.7%. Four-year or over survivor were 3 patients who underwe nt a lobectomy with R2a. The patients undergoing lobectomy had a signi ficantly better prognosis compared with patients with partial resectio n (p<0.05). The patients with R2a had significantly less local recurre nce than patients with R1 or R0 (p<0.05). We conclude that lobectomy w ith R2a is suitable treatment for metastatic lung cancer.
