[Surgical treatment of pulmonary metastases from rectocolic cancers. Apropos of 21 cases].

The authors report 21 cases of pulmonary metastases from operated cases of rectal and colonic carcinoma. Half the patients were aged between 60 and 70 years. In all cases except one the primary tumour was known and treated surgically before the metastasis occurred. The authors emphasize the necessity of radiological supervision of the chest after operation and recall that neither chemotherapy nor radiotherapy should be undertaken without prior histological confirmation. It is possible to remove the metastases by surgery but a high percentage require pneumonectomy i.e. it is necessary to take the same precautions before operation as for primary carcinoma of the bronchus. The operative mortality was nil, and the five year survival rate 18 p. 100.
