CONTACT SPECIALISTWhat are complex oncological resections?
Complex oncological resections are high technical difficulty surgical interventions performed to remove locally advanced tumors affecting multiple organs or anatomical structures. The goal is to achieve complete resection with tumor-free margins (R0).
These surgeries require highly specialized multidisciplinary teams, detailed preoperative planning, and advanced technical resources. Despite their complexity, they offer the only cure option for many patients with advanced tumors.
Types of complex resections
We perform various types of complex oncological surgeries:
Vascular resections
Surgeries involving resection and reconstruction of major blood vessels infiltrated by tumor.
Resections with bone reconstruction
Removal of bony structures (sacrum, pelvis, chest wall) with specialized reconstruction techniques.
Cytoreductive surgery
Resection of multiple tumor implants in peritoneal carcinomatosis, often combined with HIPEC.
Characteristics of complex surgery
These interventions have special characteristics that differentiate them from standard oncological surgery:
Exhaustive planning
Detailed preoperative study with advanced imaging techniques, multidisciplinary committee discussion, and three-dimensional surgical planning.
Multidisciplinary teams
Participation of multiple surgical specialties in the same operative procedure: oncological surgery, vascular, urology, orthopedics, plastics.
Extended duration
Surgeries that can extend for many hours, requiring specialized anesthetic teams and enhanced recovery protocols.
Intensive postoperative care
Postoperative management in specialized units with continuous monitoring and trained support teams.
Indications for complex resections
This type of surgery is applied in various situations:
Locally advanced tumors
Primary tumors that have grown invading neighboring structures but without distant metastases.
Retroperitoneal sarcomas
Large tumors requiring resection of multiple abdominal organs to achieve clear margins.
Tumor recurrences
Local recurrences of previously treated tumors requiring extensive salvage surgery.
Peritoneal carcinomatosis
Peritoneal tumor spread requiring peritonectomies and multiple visceral resections.
Our experience in complex surgery
At Quenet-Torrent Institute we are a reference center in complex oncological surgery. Our team has extensive experience in multivisceral resections, salvage surgery, and procedures combining techniques from multiple specialties.
Each case is evaluated individually in our tumor board, where oncologists, radiologists, surgeons from different specialties, and other professionals design the optimal strategy for each patient.
Pathologies that may require complex resections
Various oncological pathologies can benefit from this type of surgery.
Sarcomas
Retroperitoneal and extremity sarcomas requiring extensive surgery.

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.
