Moffitt Researchers Use Mathematical Modeling and Evolutionary Principles To Show Importance of Basing Treatment Decisions on Tumor Responses

Moffitt Cancer Center

TAMPA, Fla. – Cancer patients are commonly treated with the maximum dose they are able to withstand that does not cause too many toxic side effects.  However, many patients become resistant to these treatments and develop cancer recurrence.  Researchers at Moffitt Cancer Center are using mathematical modeling based on evolutionary principles to show that adaptive drug treatments based on tumor responses to prior treatment are more effective than maximum-tolerated dose approaches for certain tumor situations.
