Recent updates in BRAFV600E-mutant metastatic colorectal cancer treatment
In 2020, approximately 1.9 million people were diagnosed with colorectal cancer (CRC) globally1. At present, survival rates for the metastatic CRC (mCRC) population are poor, with less than 20% of people living for more than five years after diagnosis across Europe. Mutations in the BRAF gene occur in 8%-12% of mCRC cases, 95% of which are BRAFV600E, an aggressive form associated with poor prognosis.2
The CAPSTAN study, which is the largest real-world study of its kind, has very recently been published in ESMO OPEN and described the treatment patterns of BRAFV600E-mutant mCRC in a real-world setting across Europe.2 This is the first retrospective study to assess the treatment of BRAFV600E-mutant mCRC in routine clinical practice across Europe between 2016-2020, with the aim of defining initial testing and treatment patterns, characterising the disease and treatment effectiveness, and safety.2
Watch this short video of Professor Dirk Arnold ( Head of Oncology, Haematology & Palliative care, AK Altona, Hamburg and Director, Aklepios Tumorzentrum, Hamburg) to find out his perspectives on what the CAPSTAN study has shown and why these findings are important for patients diagnosed with BRAFV600E-mutation mCRC.
Data from this study clearly shows that patients with a BRAFV600E-mutation are presenting with more advanced and aggressive disease compared to CRC overall.2
Only 52.5% of patients were able to receive a second line of treatment, highlighting the need for close monitoring and more effective treatment options. This may improve the outcomes for patients with BRAFV600E-mutant mCRC, and allow more patients to receive further treatment.2
In addition, the study’s findings highlight the importance of testing for BRAFV600E-mutations to personalize and optimize treatment.2
While the treatment options are limited for patients with this aggressive and unique type of mCRC, the publication of the CAPSTAN study and the updates to the ESMO guidelines demonstrate a steadfast commitment by the CRC community to generate data and recommendations to help understand and improve treatment practices for this underserved patient population in the future.
