In another retrospective comparison of CAB and BCR in hyperprolactinemia by Arduc et al. [17], CAB was found more effective than BCR in controlling symptoms of hormone excess, normalization of PRL (87.4 vs. 41.4%) and tumor shrinkage (79.8 ± 39.1 vs. 54.1 ± 55.3%). Here, BCR is linked to hyperprolactinemia.
