The High Risk Digestive Tumour Prevention and Consultation

"Patients with hereditary colon cancer syndrome may present tumours in other areas of the digestive system or in other organs. For this reason, their follow-up in a specialised unit is indispensable".


The High Risk Digestive Tumour Prevention and Consultation Unit is composed of a multidisciplinary team of experts in the diagnosis and treatment of diseases of the digestive tract.

In 20% of patients affected by colon cancer, there is a close relative (parents, siblings or children) diagnosed with colon cancer.

Between 3-5% of colon cancer cases correspond to well-determined hereditary cancer syndromes, in which it is recognised at what age polyps or tumours can appear, what their evolution is, what surgical treatments should be applied and the risk of developing other tumours outside the colon that should also be monitored.

The characteristics by which a patient's profile may correspond to one of the three most frequent hereditary syndromes already determined are well-known and the presence of some of the genes responsible for this predisposition is verified.

How it works

Consultation with the specialist

After an exhaustive clinical interview with special attention to family history, the patient has a consult with our specialists.

Genetic analysis

In case the genetic study is to be carried out, it is only necessary to take 10 ml. of blood from the patient and then proceed to sequence the genome.


After the results are obtained, the patient visits the specialist once again in order to assess the results and decide, if necessary, on the best therapeutic option.

The Colorectal Cancer

The Clínica Universidad de Navarra has extensive experience and excellent results in the treatment of colorectal cancer.

In 98% of the patients the disease was controlled and the overall survival rate reached 90%.

Hereditary syndromes

Nowadays, up to five genes can be studied in the laboratory. There are two, which have already been proven to be directly responsible for the incidence of the type of colorectal cancer characterized by polyposis.

The APC gene

The probability of suffering from the disease in patients who are carriers of APC mutations is close to 100%, so it may be advisable to remove the colon as a preventive measure.

The MYH Gen

In the case of the MYH gene, determining the probability of inheriting the alteration is more complex. It does not affect individuals from two successive generations (parents and children), but occurs in relatives of the same generation.

The Lynch Syndrome

It is especially common in families where three members are diagnosed with colon cancer in two successive generations. Patients with Lynch syndrome have a 70-80% risk of colon cancer, therefore a detailed follow-up is very important.
