Abstract
Seventy-three human tumors and adjacent nonneoplastic tissues were analyzed immunohistochemically for the presence of growth-hormone-releasing factor (GRF). Four of 9 pancreatic endocrine tumors, 2 of 3 appendiceal carcinoids, and 1 of 5 cecal carcinoids were immunoreactive for GRF. One of the GRF-containing pancreatic tumors was associated with acromegaly. Histologically, the growth patterns of these tumors were variable, and the distribution of immunoreactive cells was patchy and irregular. There were no normal cells that contained GRF. These results indicate that GRF production by human tumors is more common than previously thought, although clinical acromegaly may not be apparent in patients who harbor such neoplasms.
