Long-term outcomes of pseudomyxoma peritonei after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy and its relevant risk factors in China: a retrospective study

Key Points

• Long-term outcomes for pseudomyxoma peritonei (PMP) are influenced by several key risk factors, particularly tumor markers.
• Patients with elevated tumor markers showed a correlation with worse outcomes, as did those with specific histological features.
• Retrospective analysis involved detailed evaluation of the Barthel index and CC-score as critical predictors of patient outcomes.
• Findings may inform treatment strategies, but confirmatory studies are needed to validate these risk factors.
