Appendiceal neoplasms, including carcinoid tumors and adenocarcinomas, often require secondary surgery. Early diagnosis via frozen section and tailored treatment based on tumor type and size are crucial for effective management.

Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Pathology

Background:

  • Appendiceal neoplasms encompass carcinoid tumors (CT), mucinous cystadenocarcinomas, colonic adenocarcinomas (CAC), and adenocarcinoid tumors.
  • These rare tumors present diverse clinical features and therapeutic needs, often necessitating delayed surgical intervention for definitive treatment.

Purpose of the Study:

  • To outline key management principles for appendiceal neoplasms based on a review of 14 patient cases.
  • To emphasize the importance of intraoperative diagnosis and individualized treatment strategies.

Main Methods:

  • Retrospective case series analysis of 14 patients treated between 1979 and 1989.
  • Review of diagnostic and therapeutic approaches for various appendiceal neoplasm types.

Main Results:

  • Frozen section analysis aids intraoperative diagnosis of malignancy.
  • Appendectomy or right hemicolectomy is indicated based on CT size and invasion.
  • Mucinous cystadenocarcinomas and CAC require right hemicolectomy, with aggressive debulking for pseudomyxoma peritonei.
  • Adenocarcinoid tumors necessitate right hemicolectomy and oophorectomy in postmenopausal women.

Conclusions:

  • Accurate intraoperative diagnosis and tailored surgical management are vital for appendiceal neoplasms.
  • Long-term follow-up is essential due to a significant risk of secondary malignancies.
  • Treatment strategies should be individualized according to neoplasm type, size, and extent of invasion.
