Clinical summary
Colorectal tumours —colon and rectal cancer— are treated with oncological surgery prioritising complete resection and functional preservation. At Quenet-Torrent Institute (Teknon Barcelona · Memorial Publio Cordón Madrid), Dr. Patricia Tejedor coordinates the colorectal unit together with Dr. Quenet and Dr. Carlos Rodríguez, with minimally invasive and robotic surgery.
What are colorectal tumors?
Colorectal tumors include cancers affecting the colon and rectum. Colorectal cancer is the third most common cancer worldwide and the second leading cause of cancer death.
Most colorectal cancers develop from adenomatous polyps through a well-established sequence over several years. This characteristic makes screening programs particularly effective in preventing this cancer.
Surgery is the main treatment for localized colorectal cancer. With proper treatment, survival rates are very high in early stages.
Colorectal pathologies we treat
Our unit addresses the main oncological pathologies of the colon and rectum.
Rectal Cancer
Tumors located in the last 15 cm of the large intestine, with specific surgical considerations.
Locally Advanced Tumors
Complex cases requiring multivisceral resections or neoadjuvant treatment.
Peritoneal Carcinomatosis
Peritoneal spread treatable with cytoreductive surgery and HIPEC in selected cases.
Why request a second opinion for colorectal cancer?
Requesting a second opinion can provide security and clarity about the best approach.
Confirm surgical strategy
Confirm whether the proposed surgery is the most appropriate for your case.
Evaluate sphincter preservation
Evaluate whether sphincter-sparing surgery is possible in rectal cancer.
Assess laparoscopic approach
Assess whether the surgery can be performed minimally invasively.
Consider advanced options
Consider options like HIPEC for peritoneal carcinomatosis or liver metastases.
A second opinion can confirm or reframe the initial strategy, always for the patient's benefit.

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.
