Area of Science:

  • Endocrinology
  • Oncology
  • Gastroenterology

Background:

  • Pancreatic endocrine tumors (PETs) are rare neoplasms with diverse clinical presentations.
  • Understanding their origin, classification, and biological behavior is crucial for diagnosis and treatment.

Purpose of the Study:

  • To provide a comprehensive review of the current understanding of pancreatic endocrine tumors.
  • To detail the classification, markers, malignancy criteria, and structural features of PETs.
  • To discuss functioning, nonfunctioning, and associated PETs, with emphasis on immunocytochemical and biological profiles.

Main Methods:

  • Review of 365 pancreatic endocrine tumors.
  • Analysis of tumor origin, classification, markers, frequency, and malignancy criteria.
  • Detailed examination of functioning, nonfunctioning, and multiple endocrine neoplasia type 1-associated PETs.

Main Results:

  • The review covers general structural features and specific characteristics of various PET subtypes.
  • Emphasis is placed on the immunocytochemical profile and biological features of different PETs.
  • Insights into the diagnosis and management of these complex tumors are provided.

Conclusions:

  • Pancreatic endocrine tumors represent a heterogeneous group of neoplasms requiring a multidisciplinary approach.
  • Accurate classification and understanding of biological behavior are key to effective patient management.
  • Further research into the immunocytochemical and biological aspects will improve therapeutic strategies.
