| pubmed-article:216855 | pubmed:abstractText | We evaluated sternal bone marrow aspiration as a routine pretreatment procedure in patients with bronchogenic carcinoma. The overall rate of identification of tumor cells by this technique was found to be low. When oat cell bronchogenic carcinoma was considered as a separate entity, the positive rate was higher. However, in no instance did the bone marrow aspiration result in a change in clinical staging. | lld:pubmed |
