Combinatietherapieën en gepersonaliseerde geneeskunde

Combination therapy combines two or more treatment regimes or cancer drugs to target cancer-related metabolic pathways in the cell.

Conventional therapies are more likely to fail because a single drug can only target one cancer-related pathway at a time. This often leads to the emergence of drug-resistant cancer cells during the course of treatment. On the contrary, combination therapy simultaneously targets different pathways and different cellular enzymes, thus reducing the chances of drug resistance.

The combination of different drugs also helps to lower their therapeutic dosage as well as increase the treatment efficiency due to a synergistic effect.

It also increases the cytotoxicity specifically in cancer cells while simultaneously reducing drug side effects on the normal cells. For example, caspase inhibitors can enter a normal cell and a cancer cell alike and inhibit apoptosis.

Similarly, the cytotoxic drug flavopiridol can induce apoptosis in both normal and cancer cells.

When both drugs are used together during therapy, the normal cells as well as cancer cells uptake both - caspase inhibitors and flavopiridol. In normal cells, both drugs cancel each other's effect, and th
