An elderly man with long-standing, non-resectable pheochromocytoma rapidly developed rectal adenocarcinoma despite close endoscopic surveillance. We determined that the patient’s colorectal cancer over-expressed M3 subtype muscarinic receptors, whereas his pheochromocytoma expressed choline acetyltransferase, an enzyme required to produce acetylcholine, a muscarinic receptor agonist. These findings suggested that acetylcholine release from the pheochromocytoma stimulated rapid growth of the rectal neoplasm. As proof-of-principle, we demonstrate here that culture media conditioned by pheochromocytoma cells stimulates proliferation of a human colon cancer cell line, an effect attenuated by atropine, a muscarinic receptor inhibitor. Our observations provide both clinical and laboratory evidence that muscarinic receptor agonists promote the growth of colorectal neoplasia.
