Metastatic Tumors of the Lung

Experience shows that metastatic tumors of the chest occur with greater frequency than generally realized. For this reason, it is mandatory to consider them as a diagnostic possibility when one is dealing with an apparently obscure diagnostic chest problem. In connection with the discussion of various neoplasms which may form pulmonary metastasis, the following items deserve particular attention.

1) The symptomatic manifestations of metastatic tumors of the chest are, in general, the same as those of primary malignant newgrowths.

2) In the diagnostic assaying of the patient due attention should be given to the past medical history, physical and x-ray findings, with special reference to a thorough search for coexistent primary tumor and enlarged superficial, peripheral lymph nodes.

3) Examination of biopsy specimens secured bronchoscopically or otherwise is of cardinal importance.

4) Exploratory thoracotomy should be resorted to when other diagnostic methods fail.

5) Surgical removal of solitary metastatic chest tumors is a feasible procedure, provided the patient's general condition is satisfactory and there is no contraindication to major chest surgery because of the inoperability of the primary tumor or the presence of metastasis in other organs.
