Drug's preliminary impact on the cancer, without exposing patients to the drug's potential side effects is needed different patients can respond completely to the same drug method for safely exposing tumors to tiny samples of many different drugs all at once. Normally in cancer and some other diseases, there are not good predictive markers. Test for therapies sequentially is needed for several weeks to many months to see that effects single therapy. To find modes to identify the optimal therapy required for patient before a treatment.
A device designed a 3-millimeter long device outfitted with isolated pockets. Each pocket was loaded with very small sample of a cancer drug which is a translational medicine and currently 16 different cancer drugs can be tested at once. The device was injected directly into melanoma, prostate, or breast cancer tumors in a group of mice. Tissue samples were then tested for the tumor reaction to the drugs. Those samples were then compared to how the mice reacted when given a drug full dosage. The device proved to be a reliable and accurate way to predict each drug's effectiveness.
