This conference proceedings investigates the complex nature of hormone-producing tumors, both those originating from endocrine glands and those with non-endocrine origins that secrete hormones. The book compiles presentations from a 1971 clinical conference, bringing together leading medical professionals to discuss the latest research and clinical observations on these challenging neoplasms. It aims to elucidate the mechanisms by which these tumors produce and secrete hormones, their diagnostic difficulties, and therapeutic strategies available at the time.

The Authority Perspective: This collection represents a snapshot of oncological and endocrinological understanding in the early 1970s. The proceedings likely offer valuable historical context for the study of hormone-producing tumors, detailing the diagnostic and therapeutic paradigms of that era. Its value today lies in tracing the evolution of research and clinical practice in this specialized field.
