Pertuzumab in Combination with Trastuzumab and Docetaxel as Adjuvant Doublet Therapy for HER2-Positive Breast Cancer:...

Breast cancer is the most clinically relevant pathology of the mammary gland and is currently the most diagnosed malignant disease among women worldwide. In breast cancer prevention, it is important to consider that the risk of developing the disease is not the same for the entire population. This pathology presents heterogeneous clinical manifestations and the most common classification is related to the following hormonal receptors: estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2), and triple-negative (TNBC). Currently, a new class of therapy is being used for cancer treatment: anti-body-drug conjugates. A bibliographic search was performed by establishing keywords and then combining them using Boolean operators OR and AND. Thus, the search equation was formulated according to the PICO search question to be used in the PubMed database. Results: Fifteen studies that met the established inclusion criteria were analyzed, and their methodological quality was assessed using the Joanna Briggs Institute approach, demonstrating high reliability in the results obtained, the analyzed studies focus on the combination of adjuvant Pertuzumab + Trastuzumab with chemotherapy for the treatment of HER2-positive breast cancer. Scientific evidence suggests that the combination of pertuzumab and trastuzumab not only improves the survival of patients with HER2-positive breast cancer but also provides a safe and flexible treatment option.
