Kim had her fourth round of chemotherapy Friday and it went as well as usual. The only new thing to report is that they've reduced her dosage of one of the chemotherapy drugs (Oncovin also known as Vincristine). A common side-effect of this drug is numbness and tingling in the fingers and Kim's had that since she started treatment. The concern is that this side-effect can sometimes become permanent. They didn't want to reduce the dosage initially due to concerns about the efficacy of the treatment. Now that they are comfortable the treatment is working they are slowly reducing the dose (she got 75% of her usual dose this time). Kim says that she can already feel the difference in her fingers so that is very promising.
