- Neoadjuvant endocrine therapy in breast cancer: current role and future perspectives(2016) BARROSO-SOUSA, Romualdo; SILVA, Danilo D. A. Fonseca Reis; ALESSI, Joao Victor Machado; MANO, Max SennaLuminal breast cancer, as defined by oestrogen and/or progesterone expression by immunohistochemistry, accounts for up to 75% of all breast cancers. In this population, endocrine therapy is likely to account for most of the gains obtained with the administration of adjuvant systemic treatment. The role of adjuvant chemotherapy in these patients remains debatable since it is known that only a small fraction of patients will derive meaningful benefit from this treatment whilst the majority will be exposed to significant and unnecessary chemotherapy-related toxicities, in particular the elderly and frail. Therefore, neoadjuvant endocrine therapy (NET) becomes an attractive option for selected patients with hormonal-receptor positive locally advanced breast cancer. In this review, we discuss the current role of NET and future perspectives in the field.
- Cardiac Safety of (Neo)Adjuvant Trastuzumab in the Community Setting: A Single-Center Experience(2014) FONSECA, Leonardo Gomes da; GAGLIATO, Debora de Melo; TAKAHASHI, Tiago K.; MAK, Milena Perez; BARROSO-SOUSA, Romualdo; TESTA, Laura; HELENA, Vanessa Petry; COSTA, Romulo de Paula; HOFF, Paulo M.; MANO, Max S.Background: Trastuzunnab improves the survival of patients with human epidermal growth factor receptor 2 (HER2)-positive breast cancer (BC). The incidence and long-term impact of trastuzumab-related cardiotoxicity in the community setting is of great clinical importance. Material and Methods: Patients with HER2-positive BC treated with (neo)adjuvant trastuzumab were retrospectively evaluated. Cardiotoxicity was defined as cardiac death or absolute decrease in left ventricular ejection fraction of at least 10% to a value less than 50%, or symptomatic heart failure. Results: We evaluated 237 patients: median age 53 years (range 27-83 years). 40.5% of these patients had received neoadjuvant and 59.5% adjuvant chemotherapy. The majority (83.9%) were treated with an anthracycline-based regimen. Median exposure to trastuzumab was 8 months (range 2-12 months). Cardiotoxicity was diagnosed in 20.2%, but symptoms only occurred in 3.8%. 41.6% recovered cardiac function. None of the risk factors were associated with cardiotoxicity. Conclusion: The incidence of trastuzumab-related cardiotoxicity found in this study was slightly higher than those reported in randomized clinical trials. Nevertheless, most patients were asymptomatic. We describe the cardiac outcomes of a non-selected population, which possibly reflects those found in the 'real world'. The risks versus benefits of trastuzumab use remain in favor of treatment, but cardiotoxicity should be monitored.
