Examining the link between circulating tumor DNA and peritoneal carcinomatosis in patients receiving PIPAC treatment

Study Evaluating the Bonds Between Circulating Tumoral ADN (ctDNA) and the Development of Peritoneal Carcinomatosis for Patients Treated With PIPAC

NA · Institut de Cancérologie de Lorraine · NCT04766502

This study is testing how levels of tumor DNA in the blood change in patients with peritoneal carcinomatosis who are receiving a special treatment called PIPAC, while also looking at how this affects their quality of life.

What this trial studies

This pilot study aims to analyze the changes in plasma circulating tumor DNA (ctDNA) levels in patients with peritoneal carcinomatosis undergoing three PIPAC sessions, spaced 6 to 8 weeks apart. Blood samples will be collected before and after each session to assess ctDNA concentration. Additionally, the study will evaluate the quality of life of participants using the EORTC QLQ-C30 survey, administered at various points throughout the treatment process. The overall duration of the study is set for 42 months.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with peritoneal carcinomatosis who are not eligible for cytoreduction surgery and have an indication for PIPAC.

Not a fit: Patients who may benefit from cytoreduction surgery or have contraindications to PIPAC will not receive benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of ctDNA dynamics and improve treatment strategies for patients with peritoneal carcinomatosis.

How similar studies have performed: While this approach is relatively novel, similar studies investigating ctDNA in cancer treatment have shown promising results.
