Clinical summary
Colon cancer is treated with oncological resection (right or left hemicolectomy) and complete lymphadenectomy, ideally via minimally invasive or robotic approach. At Quenet-Torrent Institute (Barcelona · Madrid), Dr. Patricia Tejedor leads the colorectal approach together with Dr. Quenet and Dr. Carlos Rodríguez, adding HIPEC in selected cases with carcinomatosis.
What is colon cancer?
Colon cancer is a malignant tumor that originates in the cells lining the large intestine. Most colon cancers develop from adenomatous polyps that transform over years.
Risk factors include age over 50, family history, inflammatory bowel disease, diet high in red and processed meats, obesity, tobacco, and alcohol. Early detection through screening programs significantly improves prognosis.
Surgery is the main curative treatment. With proper surgical technique and a multidisciplinary approach, survival rates are very high.
Why request a second opinion for colon cancer?
Requesting a second opinion can confirm that you are receiving the best treatment.
Evaluate minimally invasive approach
Evaluate whether the surgery can be performed laparoscopically or robotically.
Assess extent of resection
Assess whether adequate lymphadenectomy will be performed.
Review multimodal treatment
Review indication for adjuvant or neoadjuvant chemotherapy.
A second opinion can confirm or optimize the initial treatment plan.
How do we treat colon cancer?
Surgical treatment is the cornerstone for colon cancer management.
Right hemicolectomy
Removal of the ascending colon for right-sided tumors.
Left hemicolectomy
Removal of the descending colon for left-sided tumors.
Sigmoidectomy
Removal of the sigmoid colon for tumors in this location.
Complete mesocolic excision
Oncological technique that improves outcomes with adequate lymphadenectomy.
Most surgeries can be performed minimally invasively with equivalent oncological results.

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!
