[Treatment of pseudomyxoma peritonei is developing]

Area of Science:

• Oncology
• Surgical Oncology
• Gastroenterology

Context:

• Pseudomyxoma peritonei (PMP) is a rare condition characterized by mucinous tumors originating from the appendix and spreading throughout the abdominal cavity.
• Tumor cytology can range from benign to malignant, with slow progression even in less aggressive forms.
• Traditional management involved repeated tumor mass resections, offering symptomatic relief but not a definitive cure.

Purpose:

• To describe a novel therapeutic approach for pseudomyxoma peritonei.
• To evaluate the outcomes, including morbidity and mortality, associated with this new treatment modality.

Summary:

• A new treatment strategy for pseudomyxoma peritonei involves radical surgery combined with intraperitoneal lavage using a warmed cytotoxic solution.
• This approach aims to address the widespread nature of the mucinous tumor within the abdominal cavity.
• The reported morbidity rates range from 33% to 56%, with mortality rates between 0% and 18%.

Impact:

• This novel treatment offers a potential alternative for managing pseudomyxoma peritonei, a condition with limited effective therapeutic options.
• The associated morbidity and mortality rates highlight the need for careful patient selection and further investigation.
• The absence of controlled studies underscores the necessity for rigorous clinical trials to validate the efficacy and safety of this treatment.
