Appendiceal tumors and pseudomyxoma peritonei: current recommendations for clinical practice

Area of Science:

• Gastroenterology
• Surgical Oncology
• Pathology

Background:

• Appendiceal tumors and pseudomyxoma peritonei (PMP) are uncommon conditions.
• Perforated appendiceal epithelial tumors are the primary cause of PMP.
• Appendiceal mucoceles are rare and typically treated with appendectomy.

Purpose of the Study:

• To review current diagnostic and treatment recommendations for appendiceal malignancies.
• To align with guidelines from The Peritoneal Surface Oncology Group International (PSOGI) and the Czech Society for Oncology (ČOS).

Main Methods:

• Literature review of current guidelines.
• Synthesis of recommendations from PSOGI and ČOS.
• Focus on diagnosis and treatment of PMP and appendiceal mucoceles.

Main Results:

• PMP is characterized by mucin accumulation.
• Treatment strategies vary based on tumor type and extent.
• Guidelines provide a framework for managing these rare appendiceal conditions.

Conclusions:

• Adherence to established guidelines is crucial for optimal patient outcomes.
• Multidisciplinary approaches are often necessary for complex cases.
• Further research may refine management strategies for appendiceal tumors and PMP.
