Understanding Immune Checkpoint Inhibitors
Immune checkpoint inhibitors are a type of immunotherapy that have been a game changer in metastatic colorectal cancer treatment. They primarily function by targeting proteins on immune cells that act as brakes on the immune response. Cells can sometimes exploit these 'checkpoints', allowing them to evade detection and destruction by the immune system.
The most notable checkpoints include PD-1 and CTLA-4. PD-1 inhibitors such as pembrolizumab and nivolumab work by blocking the interaction between PD-1 proteins on T-cells and PD-L1 on tumor cells. This inhibition reinvigorates T-cells, restoring their ability to attack cancer cells. Similarly, CTLA-4 blockers amplify the immune response by preventing this checkpoint from suppressing the immune reaction.
These therapies are not a one-size-fits-all solution; they are particularly effective for tumors that exhibit certain characteristics, like high microsatellite instability or mismatch repair deficiency. These conditions suggest a heightened level of neoantigens, making them more likely to provoke an immune response. However, effective usage of immune checkpoint inhibitors necessitates a thorough understanding of patient biomarkers and immune profiles.
