Item type:Publication, Real-world data of cardiotoxicity during long-term therapy with trastuzumab in human epidermal growth factor receptor-2-positive metastatic breast cancer(National Library of Serbia, 2022-12-16); ; ; Introduction/Objective. This study aims to investigate the cardiotoxicity of long-term therapy with trastuzumab in patients with HER2 positive metastatic breast cancer. Methods. A total of 48 patients with metastatic HER2 positive breast cancer were analyzed. The patients received long-term trastuzumab (time of application was longer than 20 months). The analyzed characteristics of the patients were: age, initial stage of the disease, application of anti-HER2 therapy and anthracyclines in the adjuvant setting, the number and type of applied systemic therapies concomitant with trastuzumab in the metastatic setting. Cardiac toxicity was assessed using left ventricular ejection fraction (LVEF) values at three time points: at the beginning, in the middle, and at the end of treatment period for each patient separately. Results. In 17 (35.4%) patients the trastuzumab treatment was temporary discontinued. The average time of trastuzumab therapy interval was 52.2 ? 23.5 months. The mean LVEF values were 66.73 ? 7.02%, 64.62 ? 5.7% and 63.44 ? 6.1%, respectively. The mean values of LVEF differed significantly in the observed three time points (F=4.9 p=0.009). Post hoc pairwise comparison, using Bonferonni correction, confirmed significantly lower mean LVEF values at the end point (at the end of treatment) compared with the mean LVEF values at the beginning of anti-HER2 treatment (p = 0.019), but within the reference range of LVEF ?50%. Conclusion. The data confirm good safety profile of long-term trastuzumab therapy in HER2 positive metastatic breast cancer patients considering cardiotoxicity. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, DUAL HER2 BLOCKADE WITH TRASTUZUMAB AND PERTUZAMB IN HER2- POSITIVE BREAST CANCER: SINGLE CENTER REAL WORLD DATA(Macedonian Association of Anatomists, 2020-12-30); ; ; Agents targeting the human epidermal growth factor receptor 2 (HER2) have improved outcomes of advanced HER2-positive breast cancer with durable responses. We evaluated therapy with trastuzumab and pertuzumab in early and metastatic HER2-positive breast cancer patients. In this paper we discuss the practicalities of treating patients with this combination with a particular focus on treatment in the single center setting. We retrospectively identifed patients on adjuvant and frst-line anti-HER2 therapy at The University Clinic of Radiotherapy and Oncology Skopje for at least 1 year from 2019 to 2020. Demographics, treatments and adverse events were recorded. The combination of pertuzumab–trastuzumab has established efficacy in patients with HER2‐positive advanced/metastatic breast cancer. Management of treatment related side‐effects such as diarrhea, febrile neutropenia and neuropathy typically include dose reduction or switching taxane. Specific patients with poorer tolerance of chemotherapy such may require particular management strategies.The roles of trastuzumab and pertuzumab are now very well established in the frst-line setting; identifying predictors of long-term response to these would be important in selecting which patients might beneft from entry into future clinical trials assessing the long-term beneft of these newer agents in addition.
