We present an in-depth description of resistance to targeted therapies in breast cancer. Targeted therapies discussed here include those used to treat ER+ or Her2+ breast cancers (i.e., Tamoxifen or trastuzumab) or those targeting signaling pathways aberrantly activated in triple negative breast cancer (i.e., EGFR and Wnt signaling).

In the last decade, the literature on molecular mechanisms and activated pathways in the different lymphoma categories increased exponentially, which was followed by a more diffuse and successful use of targeted therapies.

This volume, in discussing resistance to ibritumomab, will focus on the mechanism, hematological aspects, radiological and nuclear medicine aspects, and medical physics that deal with radiation dosimetry, and will outline future prospects for overcoming resistance and enhancing efficacy of ibritumomab.
