^<67>Ga scintigraphy os widely used for the purpose of detecting neoplastic lesions. We evaluated it in 101 patients with histologically proven pulmonary cancer. With respect to uptake of gallium-67, different tumor cell types showed somewhat different sensitivity to the ^<67>Ga scan. On the basis of histological findings, the positive rates with gallium-67 for squamous cell carcinoma, adenocarcinoma, small cell carcinoma, large cell carcinoma and adenosquamous carcinoma, were 90.4%, 87.0%, 88.2%, 100% and 100%. resupectively. The smallest primary tumor ovserved by us to be positive on ^<67>Ga scanning was 1.7 cm in diamter. The large lesions had a higher percentage of positive delineation, while the smaller lesions had a lower percentage. Through ^<67>Ga scintigraphy is non-invasive and useful for detecting unexpected tumors in any part of the body, it is important to consider the limitations of this examination. Usefulness of ^<67>Ga scintigraphy was somewhat limited for diagnosing bronchogenic carcinoma at an early stage or in small foci. ^<67>Ga scintigraphy in primary lung cancer shoul prove to be helpful in assessing the exten of disease.
