A study was undertaken to test whether indium 111 (111In)-labeled anti-carcinoembryonic antigen (CEA) (type ZCE 025) monoclonal intact antibody (MoAb) would concentrate in primary lung cancer enabling its detection and localization by scintigraphy. The scintigraphic results were correlated with chest radiograph, computed tomograph (CT), bronchoscopy, surgical resection, and tumor CEA analysis. Twenty adult male patients with clinical suspicion of primary lung cancer were studied. Each subject was infused with 4 to 5 mCi of 111In anti-CEA ZCE 025 MoAb, and planar and tomographic scintiphotos were obtained on days 3 and 6 or 7 postinfusion. The scintigraphy was true-positive in 12 of 16 patients with primary lung cancer, eight of nine patients with squamous cell carcinoma, and four of seven with adenocarcinoma; it was true-negative in three of four patients with benign lung disease with an overall accuracy of 75%. In seven patients with confirmed primary lung cancer, but with negative bronchoscopic findings, the scintigraphy was true-positive in four. In 11 patients with definitely positive or suspicious malignancy by bronchoscopy the monoclonal scintigraphy was positive in eight. In true-positive cases, the location and size of the lesion by 111In anti-CEA ZCE 025 MoAb imaging correlated well with CT findings and also tumor mass at surgery. Only one of 12 tumors stained positive for CEA had serum CEA levels greater than 10 ng/ml, indicating nonleakage of the tumor antigen into general circulation in early lung cancer. It is concluded that 111In anti-CEA ZCE 025 MoAb planar and tomographic imaging shows potential to serve as a noninvasive diagnostic test in the evaluation of primary lung cancer. The lung lesion is likely to be malignant if it concentrates 111In anti-CEA ZCE 025 MoAb and benign if it does not.
