Between 1960 and 1991, 103 consecutive patients underwent pulmonary resection for metastatic lung tumors in our department. Of the 103 cases 52 were males and 51 were females, aged from 21 to 83 years old. The items of the primary origin of them were 23 cases colorectal cancer, 21 of osteogenic sarcoma, 11 of soft part sarcoma, 10 of mammary cancer, 7 of choriocarcinoma, 7 of renal cancer and others. The 5 year survival of the colorectal lung metastases were examined according to the number and size of the tumors, the tumor free interval and operation modalities. The 5 year survival rate was 45%. The recent trends of surgical treatment for metastatic lung tumors show a significant decrease of surgical treatment of choriocarcinoma, however trends show a significant increase of colorectal carcinoma. The surgical treatment of the colorectal cancer metastases, not only solid metastasis and, multiple metastases but also localized liver metastasis have given satisfactory results. With the present state of chemo-therapy and radiation therapy an acceptable survival rate cannot be expected except for only some kinds of metastatic tumor, and so most other tumors should be surgical resected. In particular it is desirable that a lobectomy with lymph node dissection be performed on solid colorectal metastasis.
