ABC4 Consensus: First Latin American Meeting-Assessment, Comments, and Application of Its Recommendations.

Breast cancer accounts for a high burden among all the neoplasms in Latin America, with more-advanced stages at presentation, which could result in high mortality rates. The 4th International Consensus Conference for Advanced Breast Cancer (ABC4) is focused on standardizing therapy for advanced breast cancer (ABC) and has held 5 meetings so far. ABC4 took place in Lisbon, Portugal, from November 2 to 4, 2017; however, the first Latin American ABC conference was held in Lima, Peru, from 18 to 19 May, 2018, chaired by Fatima Cardoso, MD, PhD.

A prospective randomised evaluation of G-CSF or G-CSF plus oral antibiotics in chemotherapy-treated patients at high risk of developing febrile neutropenia.

Background: Febrile neutropenia (FN) remains a major dose-limiting complication among patients treated with chemotherapy. Haematopoietic colony stimulating factors (G-CSF and GM-CSF) made possible a significant improvement in the management of FN, both in the therapeutic and in the prophylactic approach. The use of antibiotic prophylaxis also permits a definite reduction of severe infections during neutropenia.

Second malignancies following adjuvant chemotherapy: 6-year results from a Belgian randomized study comparing cyclophosphamide, methotrexate and 5-fluorouracil (CMF) with an anthracycline-based regimen in adjuvant treatment of node-positive breast cancer patients.

Background: Alkylating agents and topoisomerase-II inhibitors have been associated with the occurrence of secondary leukemias and myelodysplastic syndromes in breast cancer patients treated with adjuvant chemotherapy. Conversely, data on the occurrence of second solid malignancies in this setting are scarce.

Patients And Methods: This study retrospectively evaluates the occurrence of second hematological and solid malignancies in the context of a prospective multicenter phase III trial comparing epirubicin-cyclophosphamide at intermediate doses (EC), or at full doses (HEC), with classical cyclophosphamide, methotrexate and 5-fluorouracil (CMF) in 777 patients with early breast cancer.
