Study summary

This trial pursues studying a compassionate treatment option for patients with inoperable pseudomyxoma peritonei through percutaneous administration of bromelain + N-acetylcysteine (NAC) in order to decrease tumoral volume. Secondary endpoints are the decrease of ascites, compressive symptoms and pain through the dilution of mucins, which would better intestinal blockage.

What researchers measure

Primary outcomes

  1. Tumoral Mass Change

    Tumoral mass change calculated through CT Scan or Magnetic Resonance categorized regarding the biggest diameter per abdominal region

    Time frame: Day 3, Day 7 (if it applies),1 month and 12 months after treatment is finished.

Secondary outcomes

  1. Symptoms improvement

    Symptoms progression evaluated through QLQ-C30 questionnaire (life quality questionnaire)

    Time frame: Basal visit, 1 month and 12 months after treatment.

  2. TTP (Time to tumor progression)

    Period of time free of tumor progression.

    Time frame: Period of 12 months after treatment.

  3. Overall survival

    Time until death from any cause

    Time frame: Period of 12 months after treatment.

  4. Tumoral DNA diminution in biological samples

    Diminution of tumoral DNA amount found in mucin and blood samples

    Time frame: Basal visit, all treatment visits and 12 months after treatment is finished.
