On-treatment Biomarkers in Metastatic Colorectal Cancer for Life

Recruiting now

Conditions studied: Metastatic Colorectal Cancer, Chemotherapy Effect, Peritoneal Metastases, Liver Metastasis Colon Cancer, Lung Metastases

In brief

By virtue of an increased strategic use of cytotoxic and biological agents, and more options for locoregional treatment, the survival of patients with metastatic colorectal cancer (mCRC) has improved considerably in the past decades. The personalized approach to systemic treatment is further aided by the use of complementary molecular biomarkers. However, the evolutionary dynamics of mCRC, a disease harnessed by multiple adaptive genetic alterations towards its final stages, poses a particular challenge to single-sample biomarker analyses and standardized linear treatment protocols. The aim of the On-treatment biomarkers in metastatic ColorectAL cancer for Life (On-CALL) study is to generate further knowledge on the evolutionary progression of mCRC during treatment, and to elucidate the mechanisms underlying the therapeutic failure still seen in a substantial number of patients. The On-CALL study is a prospective, single-arm observational study. All patients diagnosed with synchronous mCRC treated with curative intent at Skåne University Hospital will be invited to participate. Clinical and histopathological data will be compiled at study entry. An individual tissue microarray block with samples from resected primary tumours and metastases representing the full extent of the tumour spread will be constructed for each patient. Blood samples will be drawn for biomarker analyses at multiple time points prior to, during and after systemic treatment. DNA sequencing of tumour tissue and circulating tumour DNA (ctDNA) will be performed to define the spatial clonal landscape in primary tumours and metastases, as well as over time.
