ERBB2 and urinary bladder cancer: Reliable information related to the spatial distribution of receptor expression and dosimetry for each patient, and possibly also for prediction of therapy results, require a well functioning whole body, non-invasive nuclear medicine based method as suggested for other types of tumors.31–35 However, the high frequencies of expression of both EGFR and HER2 in primary tumors and metastases in our study indicate that many, maybe most, urinary bladder cancers are of interest for targeting with molecules that deliver radionuclides to these receptors.
