“Are we theeeeere yet?” Every parent knows that familiar whining from the back seat of the car. Sometimes, I feel as impatient as the kid in the back of the car. Although EGFR mutation helps with predicting tarceva (erlotinib) response, I want markers for cytotoxic (traditional) chemotherapy now. Unlike the parent in the driver’s seat of the car, I’m not entirely sure where we are, or where we’re going. Sometimes I feel as though I’m driving in the dark. Could molecular markers be the headlights?
