Clinical summary
Peritoneal mesothelioma —a rare primary tumour— is treated with complete cytoreduction and HIPEC with cisplatin, achieving 5-year survival rates of 50-70% in epithelioid variants. At Quenet-Torrent Institute (Teknon Barcelona · Memorial Publio Cordón Madrid), the team of Dr. Quenet and Dr. Torrent is a reference centre for this uncommon condition.
What is peritoneal mesothelioma?
Peritoneal mesothelioma is a rare malignant tumor originating from the mesothelial cells that line the peritoneal cavity. It differs from pleural mesothelioma (lung lining) in location, behavior, and prognosis.
There are three main histological subtypes: epithelioid (most common, ~70%, best prognosis), sarcomatoid (worst prognosis), and biphasic (mixed, intermediate prognosis). Subtype is the main determinant of treatment strategy.
While asbestos exposure is a recognized risk factor, 30-50% of cases have no identified cause. BAP1 gene mutations are present in a significant proportion.
In epithelioid cases selected for surgery, cytoreductive surgery with HIPEC achieves median survival of 50-90 months — a dramatic improvement over the approximately 12 months seen without specific surgical treatment.
Why request a second opinion for peritoneal mesothelioma?
This rare tumor requires evaluation by centers with documented experience in this specific condition.
Evaluate surgical candidacy
Assess whether complete cytoreduction is technically and oncologically feasible.
BAP1 and molecular testing
Identify genetic mutations that may influence prognosis and treatment selection.
Immunotherapy integration
Evaluate how immunotherapy (nivolumab + ipilimumab) can be integrated into the overall treatment strategy.
In rare tumors like peritoneal mesothelioma, treatment at a specialized center with documented experience is essential.
How do we treat peritoneal mesothelioma?
Treatment depends critically on histological subtype and is planned in a multidisciplinary committee.
Complete cytoreductive surgery
For epithelioid cases: removal of all visible tumor implants and affected peritoneal surfaces.
HIPEC with cisplatin/mitomycin C
Hyperthermic intraperitoneal chemotherapy immediately after cytoreduction to treat microscopic residual disease.
Immunotherapy
Nivolumab + ipilimumab for unresectable cases or as perioperative treatment in selected candidates.
Systemic chemotherapy
Pemetrexed-based regimens for advanced or unresectable disease.
All cases are discussed in a specialized multidisciplinary tumor board to individualize the optimal treatment sequence.

Frequently asked questions about peritoneal mesothelioma
Answers to the most common questions about diagnosis, treatment, and prognosis.
Is peritoneal mesothelioma the same as pulmonary mesothelioma?
No. Both originate from mesothelial cells, but in different locations. Peritoneal mesothelioma has a better prognosis thanks to the possibility of surgical treatment.
Is peritoneal mesothelioma always caused by asbestos?
No. Although asbestos is a known risk factor, 30-50% of cases have no documented exposure. BAP1 genetic mutations and other factors are involved in a significant.
What is the life expectancy with peritoneal mesothelioma?
With CRS + HIPEC in epithelioid mesothelioma: median survival 50-90 months and 5-year survival 50-70%. Without specific surgical treatment: median survival approximately.
What histological subtypes exist?
Epithelioid (best prognosis, ~70%), sarcomatoid (worst prognosis, surgery not recommended), and biphasic (intermediate). Subtype is the most critical factor in treatment.
What role does immunotherapy play?
Nivolumab + ipilimumab is now first-line treatment for unresectable mesothelioma. Integration with surgery in resectable cases is being studied in clinical trials.
Where can I receive this treatment safely?
In specialized centers with experience in peritoneal mesothelioma, like Quenet-Torrent Institute, one of the leading centers for this condition in Spain.

Wonderful surgical team, among the best out there. Dr. Torrent (expert in peritoneal carcinomatosis) is an exceptional surgeon and an even better person. His coordinator is super kind, fast and efficient. The human treatment is great and the results are too. This is of vital importance for cancer patients.

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.
