Colorectal cancer (CRC) is an important public health issue, being the second leading cause of cancer death worldwide [1, 2]. Although the prognosis of patients with CRC has improved during the past decades, almost half of all CRC patients with localized disease will relapse after initial treatment. Even so, the median survival time for patients with metastatic CRC (mCRC) is about 30 months [3].
