Clinical summary
Peritoneal carcinomatosis of gastric origin is approached with cytoreductive surgery and HIPEC in patients with limited PCI, within strict oncological protocols. At Quenet-Torrent Institute (Teknon Barcelona · Memorial Publio Cordón Madrid), Dr. Juan José Torrent and Dr. François Quenet lead the multidisciplinary committee that selects eligible cases.
What is gastric carcinomatosis?
Gastric carcinomatosis is the spread of gastric cancer cells to the peritoneum. It is one of the most common forms of gastric cancer progression and has traditionally been considered a terminal condition.
However, advances in multimodal treatment have shown that in carefully selected patients, the combination of cytoreductive surgery and HIPEC can significantly improve survival and even offer cure potential in limited cases.
Strict patient selection is key. Results depend on the extension of peritoneal disease, response to systemic treatment, and achievability of complete cytoreduction.
Why request a second opinion for gastric carcinomatosis?
Requesting a second opinion can reveal treatment options not initially considered.
Evaluate response
Evaluate response to systemic chemotherapy and surgical options.
Compare approaches
Compare the palliative approach with potentially curative options in specialized centers.
Clinical trials
Consider participation in clinical trials with innovative treatments.
A specialized evaluation can change the prognosis in selected patients.
How do we treat gastric carcinomatosis?
Treatment in selected cases combines systemic chemotherapy with locoregional surgery.
Neoadjuvant chemotherapy
Systemic treatment to evaluate response and select candidates.
Cytoreductive surgery

In the public healthcare system they gave my father a maximum of one year to live. They only offered him chemo and no hope, said it was impossible, that nothing could be done. He had several tumors inside the peritoneal sac with metastases. A year and a half later he is clean, completely cured. His latest PET scan came back clean. We are very happy. Thanks to Dr. Torrent and his team. THANK YOU.

I am a 63-year-old patient. They detected adrenal gland cancer and told me there was nothing to be done. I sought a second opinion and they told me about the Quenet Torrent team, specialists in complex operations. Dr. Torrent, from the first moment, told me they could operate. They operated and removed a large tumor mass. I spent a week in the ICU and a month on the ward. Every day he came morning and evening, no matter Saturday or Sunday. Never throw in the towel. I am happy to have found these professionals who gave me my life back. Thank you.

I have peritoneal carcinomatosis. Sending my diagnosis to every center, practically all agreed on palliative chemo with little survival time since I had very aggressive cell types. Until we reached Dr. Quenet, Dr. Torrent and their team. I can only confirm what their CV announces: they are far ahead of the rest. They saved my life, at surgery the harmful cells everyone diagnosed (and used to refuse to operate) were not there. This intervention has become the best investment of my life.

The best decision of my life was finding this excellent team of surgeons who saved my husband's life. At a prestigious international clinic in Madrid he was given up for lost with advanced peritoneal carcinomatosis from appendiceal cancer, and thanks to them, the best professionals in this field, he was operated on very successfully. A perfect recovery with no complications, because they were on top of his progress at all times. They have a great quality: from the start they were very honest and close. I can only be deeply grateful; we went to buy time and thanks to them my husband got his life back.

Dr. Torrent is a brilliant surgeon and a very easy-going and polite doctor. When talking with him you can easily grasp his qualities as a professional and human being: perseverance, innate curiosity and passion for learning, humility, honesty and empathy. Having surgery is always an intense experience, anxieties arise and one feels very vulnerable. All of that being said, as his ex-patient I can assure that throughout the process his care and professionalism were absolutely outstanding. I felt safe, supported by him, knowing I was in good hands. I will be forever grateful. Moltes gràcies Dr. Torrent!
