Pseudomyxoma Peritonei
Conditions
Keywords
pseudomyxoma peritonei, n-acetylcysteine, acetylcysteine, NAC, bromelain
Brief 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.
Interventions
0.5mg per mL of total tumor volume calculated, administered percutaneously

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Tumoral Mass Change | Day 3, Day 7 (if it applies),1 month and 12 months after treatment is finished. | Tumoral mass change calculated through CT Scan or Magnetic Resonance categorized regarding the biggest diameter per abdominal region |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Symptoms improvement | Basal visit, 1 month and 12 months after treatment. | Symptoms progression evaluated through QLQ-C30 questionnaire (life quality questionnaire) |
| TTP (Time to tumor progression) | Period of 12 months after treatment. | Period of time free of tumor progression. |
| Overall survival | Period of 12 months after treatment. | Time until death from any cause |
| Tumoral DNA diminution in biological samples | Basal visit, all treatment visits and 12 months after treatment is finished. | Diminution of tumoral DNA amount found in mucin and blood samples |
