In colorectal, pancreas, bladder, prostate, breast, and ovarian carcinoma, EpCAM was more intensely positive in tumor cells than in the corresponding normal tissues.9 Ep-CAM-specific antibodies have been used to image and detect primary tumors and metastases in patients with small cell lung cancer and non-small cell lung cancer. The gene discussed is EPCAM; the disease is small cell lung carcinoma.
