About
Colorectal cancer is the most common cancer and represents the second leading cause of cancer deaths in Spain. Patients with metastatic disease are usually treated with a combination of chemotherapy and anti-target drugs with the intention of reducing the tumour burden in order to operate the metastases (which translates into a considerable increase in survival) or improve symptomatology and prolong life as much as possible. Although immunotherapies have been a breakthrough in the field of oncology, they are effective in less than 5% of colorectal cancer cases.
One of the biggest problems in achieving clinicians' objectives is the development of resistance to treatments, which sooner or later affects almost all patients. This research group investigates how and why colorectal tumours become resistant to conventional treatments with the aim of finding predictive markers of response and identifying tumour vulnerabilities that allow the use of alternative existing treatments or develop new ones. The group also investigates why immunotherapy is ineffective in this type of cancer and how this situation can be reversed.
The researchers of this group do so by using pre-clinical models and samples from the patients. Their ultimate goal is to develop new tools for personalised medicine that improve patients' survival and quality of life.
Keywords: Resistance, chemotherapy, colorectal cancer, biomarkers, pre-clinical models, immuno-oncology.

Research lines
Deciphering mechanisms of resistance to treatment in colorectal cancer
Finding predictive biomarkers for treatment selection
- To study somatic genetic polymorphisms within genes involved in pharmacodynamics and pharmacokinetics processes affecting the effectiveness of a given chemotherapeutic drug or its related toxicity.
- To study tumour gene and/or protein expression patterns that could be associated with resistance to chemotherapy and that could serve as clinical biomarkers to select treatments.
Development and implementation of in vitro and ex vivo models of acquired resistance to different anti-cancer therapies
- To study changes in patterns of gene or protein expression and DNA-methylation associated with resistance acquisition by using high-throughput techniques.
- To elucidate the mechanisms responsible for resistance acquisition to chemotherapeutics and define new putative predictive biomarkers.
- To identify new ways of therapeutic intervention able to revert this chemoresistance.
