Summary

This study tests whether a lower dose of heated chemotherapy given during surgery works as well as a higher dose for people with pseudomyxoma peritonei, a rare cancer that spreads in the abdomen. About 176 participants will be randomly assigned to receive either the lower dose over 60 minutes or the higher dose over 90 minutes. The goal is to see if the lower dose can control the cancer just as well while causing fewer side effects.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Mitomycin C (heated chemotherapy given during surgery)
What this could lead to
If the lower dose works as well, it could mean fewer complications for patients while still controlling the cancer effectively.
What could go wrong
This is a single study with 176 participants, so results may not apply to everyone. The lower dose might be less effective at preventing cancer return.

Inclusion Criteria: 1. Clinical and/or radiological diagnosis of pseudomyxoma peritonei from a primary mucinous epithelial tumours of the appendix (low and high grade) 2. The extent of intraperitoneal disease must be deemed to be amenable to complete cytoreduction (CC0-1, i.e. residual disease of \< 2.5mm in diameter). 3. Patients aged 16 or more and capable of giving informed consent for the procedures and interventions of the current trial. 4. ECOG performance status 0-1. Exclusion Criteria: 5. Patients who have previously undergone cytoreductive surgery and/or intraperitoneal chemotherapy. 6. Clinical evidence or suspicion of metastases to sites different than peritoneum or intra-abdominal lymph nodes 7. Hypersensitivity to the active substance (mitomycin) or its excipients (mannitol, hydrochloric acid, sodium hydroxide) 8.
