Patient stories could unlock new treatments for rare appendix cancer

This study is building a global patient registry to collect real-world information from people diagnosed with appendix cancer or pseudomyxoma peritonei (PMP), a rare condition where tumors spread in the abdomen. Participants and caregivers share details about their symptoms, treatments, and outcomes over time. The goal is to better understand how these diseases progress and to provide the data needed to design future clinical trials and improve care.
