In a second example, TFIZ1 and TFF1 were detected in adjacent normal mucosa, neither was detected in the primary tumour, but TFF1 was expressed by metastatic carcinoma cells located within a lymph node from the greater curve and by metastatic carcinoma cells that have invaded fat from the right paracardial area (Fig. 6E). The gene discussed is TFF1; the disease is neoplasm.
