Surgery of lung metastases of breast cancer: analysis of 40 cases
Between 1987 and 1995, 52 breast cancer patients had a surgical resection of lung secondaries. In 40 patients, the diagnosis of metastatic breast cancer could be confirmed following pathological examination. Five-year survival rates of these 40 patients was 54 8 % and 5-year disease free survival was 30 8%. The median survival (70 months) of these patients was better than that of 57 patients with isolated lung metastases who had been treated conservately (chemo- or/and hormonotherapy) during the same time interval. Twenty-six patients benefitted from a radical excision and had a longer disease free interval (42 versus 27 months, p = 0.03) than patients who had had a wedge resection. Overall survival was not significantly different (71 versus 41 months, p = 0.07). We feel that isolated lung nodules may best be treated by radical (segment or lobe) excision, in particular since preoperative differential diagnosis with primary lung cancer may be difficult. In the presence of multiple nodules, first line medical treatment by chemo- or hormonotherapy should be advocated, allowing to reduce the tumor load and to optimize survival in association with surgery.
