Re: FDA news release on pertuzumab approval (perjeta)
Not withstanding the availability/production issues with this drug, does the FDA approval require that orignal early stage Her2+ patients first be tested to confirm their cancer is still Her2+ before receiving Perjeta? I ask this question since I believe I read here that sometimes the breast cancer can change its expression of the Her2 receptor either over or under as it progresses.--bird
