[Indications for surgical resection of lung metastasis from breast cancer--considerations according to the mechanism of extension of metastases].
The indications for surgical treatment of lung metastasis from breast cancer were analyzed according to the extension mode of the metastasis. Of lung lesions that seemed operable roentgenographically at the time of their first manifestation, about half developed new metastatic nodules within six months thereafter, while the other half did not do so for more than two years. No clinicopathologic findings at the time of mastectomy were helpful to differentiate the two groups, except that a cancer-free interval of less than a year fell exclusively into the former group. Thus, the only way to determine the indications is to watch the lesions for six months with chemo-endocrine therapy.
