Most of us love cocktails. . .Manhattan, gin and tonic etc. We know, depending on what we use and how they are mixed, they may taste different.
Well, for the treatment of colon cancer patients we have different cocktails to choose from such as FOLFOX and FOLFIRI. Both are combinations of 5-FU and leucovorin and either irinotecan or oxaliplatin. Both regimens have similar efficacy and similar extent of side effects, with oxaliplatin having more neurotoxicity and irinotecan more diarrhea.
However, depending how you mix and deliver the three drugs you may have significant differences in toxicity. It is amazing what differences exist among oncologists in how they mix up their chemotherapeutic cocktails. Not only the doses but also the timing of administration can differ dramatically, which can result in differences in toxicities for patients.
