patient with breast cancer, receiving weekly treatments with the chemotherapeutic agent vinorelbine. For some time she has experienced a tingling feeling on the side of the neck, just over the access port catheter, at or shortly after the infusions. If we wait a few minutes between iv betamethasone (4 mg) and vinorelbine infusion she does not get this sensation, however. The access port is patent with good flow and brisk blood return.
What is this and why the difference with/without the wait?
