Clinical summary
Peritoneal carcinomatosis from ovarian cancer is treated with complete cytoreductive surgery and HIPEC, with 5-year survival rates above 50% in selected patients. At Quenet-Torrent Institute (Barcelona · Madrid), the team of Dr. Quenet, Dr. Torrent and Prof. González Bayón performs primary, interval and salvage cytoreductive surgery according to stage.
What is ovarian carcinomatosis?
Ovarian carcinomatosis occurs when tumor cells spread through the peritoneum, the membrane that lines the abdominal cavity and its organs. This dissemination can originate from different types of cancer, the most frequent being colorectal, gastric, ovarian, peritoneal mesothelioma, and appendicular tumors such as pseudomyxoma peritonei.
It is an advanced condition, although not necessarily terminal. Advances in oncological surgery have made it possible to offer real treatment alternatives with curative intent, particularly when associated with the HIPEC technique in cases of pseudomyxoma peritonei, peritoneal mesothelioma, and ovarian cancer.
Why request a second opinion for ovarian carcinomatosis?
Requesting a second medical opinion is not a sign of distrust, but a responsible attitude towards a complex diagnosis.

Compare options when initially only palliative treatment has been proposed.
Evaluate experience
Evaluate the experience and results of the proposed center.
Updated treatment
Ensure you are receiving the most up-to-date and effective treatment available.
In pathologies like ovarian carcinomatosis, time is a crucial factor, but so is making informed and well-founded decisions.
How is ovarian carcinomatosis treated?
The most effective treatment for this pathology is cytoreductive surgery, which seeks to eliminate all visible macroscopic disease, sometimes followed by HIPEC, a heated chemotherapy perfusion directly into the abdominal cavity.
Single surgical procedure
It is performed in a single surgical procedure, under general anesthesia.
Localized chemotherapy
Allows the application of high-temperature localized chemotherapy, which increases its efficacy on residual tumor cells, without the usual systemic toxicity.
Selected patients
It is indicated exclusively in selected patients, after evaluation by an oncology committee.
Comprehensive assessment
At Quenet-Torrent Institute, a comprehensive assessment of each case is performed to determine treatment viability.

Frequently asked questions about peritoneal carcinomatosis
Answers to the most common questions about diagnosis, treatment, and prognosis.
Is peritoneal carcinomatosis always terminal?
No. In selected patients, cytoreductive surgery and sometimes its combination with HIPEC can have curative intent.
Who are candidates for surgery?
Patients evaluated by a multidisciplinary oncology committee considering disease extent, general condition, and response to previous treatments.
What risks does the intervention involve?
Complex procedure with inherent risks, but expert team and international protocols minimize complications.
What is the estimated duration of the procedure?
Generally 6-12 hours in a single surgical procedure, depending on case complexity.
How long is hospitalization required?
7-14 days average, depending on individual postoperative evolution.
Is it possible to repeat surgery in case of recurrence?
Yes, in selected patients with localized recurrence and good general condition.
What is the difference between HIPEC and conventional chemotherapy?
HIPEC applies chemotherapy directly into the abdominal cavity at high temperature (41-43C), increasing efficacy and reducing systemic toxicity.
What prognosis can be expected after surgery with or without HIPEC?
Varies according to tumor origin and quality of cytoreduction. Survival rates significantly higher than conventional systemic treatments.
What types of tumors respond best to this approach?
Pseudomyxoma peritonei, peritoneal mesothelioma, and ovarian cancer show the best responses to combined treatment.
What distinguishes Quenet-Torrent Institute from other centers?
Accumulated experience in thousands of procedures, international multidisciplinary team, state-of-the-art technology, and protocols based on international scientific evidence.

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.

Excellent professionals, especially Dr. Torrent, attentive at all times to the patient (my wife), operated for peritoneal pseudomyxoma. They helped us with all our needs since we came from outside Barcelona. Thank you Elisabeth. We are very grateful to Quenet Torrent Institute, thank you for everything.

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.
