Abstract
Over a 5-year period 57Co-bleomycin scintigraphy for tumor detection was performed with a large-field-of-view gamma camera. The scintigrams of 268 patients with lung cancer, with a benign lesion, or with no abnormality in the chest, were reviewed. A sensitivity of 96% was found. In a group of 193 patients in whom a preoperative pathologic diagnosis could not be obtained sensitivity was 95%, specificity was 87%. Correlation between tumor size and tumor-to-non-tumor ratio was established for squamous cell carcinoma, adenocarcinoma, and small cell anaplastic carcinoma. Adenocarcinomas were smaller and showed lower tumor-to-non-tumor ratios than other histologic types. In squamous cell carcinoma a possible correlation between tumor-to-non-tumor ratio and histologic differentiation was investigated, but could not be established. It is concluded that 57Co-bleomycin scintigraphy is helpful in the evaluation of patients with possible lung cancer in whom a preoperative pathologic diagnosis cannot be obtained.
