Research Summary

Dr. Llor’s research interests relate to colorectal cancer. He focuses his studies on forms of colorectal cancers that can be passed along through the genes and thus can affect multiple members in a family. He is trying to unveil specific genes that can be responsible for some of these cases and how cancers in these families develop. He is also interested in understanding why some racial groups are more prone to develop colorectal cancer than others and how environmental factors can play a key role in colorectal cancer development

Specialized Terms: Mismatch Repair Proficient Hereditary Non-Polyposis Colorectal Cancer; MSS-HNPCC: Lynch syndrome; Colorectal Cancer Disparities: Colorectal Cancer in African Americans

Extensive Research Description

Dr. Llor obtained his MD degree at the Autonomous University of Barcelona and his PhD in molecular biology at the University of Barcelona. He completed his Internal Medicine Residency at the University of Chicago-Lutheran General Hospital Program and his GI fellowship at the University of Illinois at Chicago. In 2014, Dr. Llor joined Yale University as co-Director of the Cancer Genetics and Prevention Program, Medical Director of the Colorectal Cancer Prevention Program, and more recently Associate Director of Cancer Screening at Yale's Cancer Center.

A clinically active gastroenterologist, Dr. Llor's research and clinical interests relate to GI cancer, mostly colorectal and stomach, with an emphasis on genetics and disparities. He spearheaded and carried out three large prospective cohorts of colorectal cancer patients and controls that produced a wealth of information. Some important contributions from Dr. Llor's lab include the description of the best diagnostic approaches to Lynch syndrome diagnosis; clinical and molecular characterization of mismatch repair proficient hereditary non-polyposis colorectal cancer (type X); identification of distinct clinical and molecular features of colorectal cancers in young African Americans, phenotypic features of hereditary gastric cancer.

Some of the themes of my research include:

1. Lynch syndrome (LS) is the most common inherited CRC syndrome and it is characterized by cancer development at a young age and very high risk of different extra-colonic malignancies. Affected family members require intensive cancer surveillance. LS is caused by mutations in the mismatch repair genes that result in tumor microsatellite instability (MSI) and loss of expression of the corresponding protein. A tremendous challenge is still diagnosing individuals with LS as patients do not have an obvious pre-morbid phenotype (development of multiple polyps) that could suggest the presence of this syndrome. Thus, establishing the best diagnostic approaches has been an important priority over the last few years. I have performed several studies that have become seminal in the diagnostic process of LS.

2. African Americans have the highest incidence and mortality from colorectal cancer and several studies have suggested some clear biological differences. In order to better understand these differences while taking into account social and environmental factors, I established and lead the Chicago Colorectal Cancer Consortium (CCCC), a multiethnic cohort that recruited over 600 patients with CRC of which over 60% are African Americans. The CCCC established a strong team of collaborators working towards the identification of genetic-environmental interactions and socio-economic aspects. Some important findings have already been published and other manuscripts are under preparation. As these is a rich repository of clinical data and biological samples, we expect many more studies will be published in the future based on this cohort

3. Colorectal cancer is among all common malignancies one with the highest percentage of familial clustering. In fact, several hereditary colorectal cancer syndromes have already been well characterized, which has allowed the implementation of genetic screening and prophylactic and preventive measures. Nevertheless, about half of the families showing a pedigree strongly suggestive of an autosomal dominant inheritance pattern with no polyposis phenotype do not have known genetic predisposing mutations identified so far. I have carried out different studies to characterize these patients, investigating germline associations as well as distinctive carcinogenic processes in order to identify their potential biological cause. Several key features have been identified and these describe this group as a different colorectal cancer entity.
