Prognosis in peritoneal carcinomatosis does not depend on a single figure. Tumour type, extent, cytoreductive surgery and the patient's condition determine the course of the disease.
Clinical guide to the Peritoneal Cancer Index (PCI): what it measures, how it is calculated, how it is applied in treatment decisions and its relationship with cytoreductive surgery.
Dr. Juan José Torrent answers the most common questions from patients about ovarian cancer surgery: risks, recovery, fertility, and when to seek a second opinion.

Yes, you can live with liver metastases, and some patients are cured. When they come from colon or rectal cancer and are removed completely, 40% to 60% of patients are alive 5 years later.
Receiving a cancer diagnosis is a difficult moment. A second medical opinion helps you make informed decisions about treatment.
Dr. Juan José Torrent, founder of Quénet Torrent Institute and oncological surgeon, explains in the video what the PIPAC technique involves. PIPAC (Pressurized Intraperitoneal Aerosol Chemotherapy) is a technique used to treat patients with inoperable peritoneal carcinomatosis. This procedure delivers chemotherapy as an aerosol inside the abdominal cavity to reduce the tumour mass and turn unresectable tumours (those that cannot be removed by surgery) into resectable ones.
