Attackers and defenders: tumor buds and lymphocytes as morphological biomarkers in colorectal cancer

Tumor budding (TB) and tumor-infiltrating lymphocytes (TILs) are significant components of the tumor microenvironment emerging as prognostic biomarkers of colorectal cancer (CRC). TB is defined as single cells or clusters of up to four cancer cells dissociated from the tumor body and invading the surrounding stroma. Growing evidence supports TB's attacker effect in pT1 CRC and stage II colon cancer as an indicator of lymph node metastasis and unfavorable survival, respectively. TILs, in contrast, represent the host's ability against tumor progression as a defender.
