Background: We conducted this meta-analysis to compare the efficacy and safety of PARP inhibitors with or without chemotherapy versus chemotherapy alone for advanced breast cancer. Methods: A meta-analysis and trial sequential analysis were performed using RevMan 5.2 analysis software. Results: Six eligible randomized clinical trials involving 2080 patients were included. Regimens containing PARP inhibitors were significantly associated with higher objective response rate, longer progression-free survival and overall survival. The PARP inhibitor regimen group had a significantly higher rate of grade ≥3 thrombocytopenia than the chemotherapy-only group. Conclusion: Regimens containing PARP inhibitors are effective and safe for BRCA-mutated advanced breast cancer patients. The efficacy appears to be only marginal in patients with BRCA status unselected.

Single Agent Chemotherapy

Chemotherapy of breast cancer is still the area of intensive research. Based on mathematical model of tumor cell growth kinetics, articulated by Larry Norton, novel concept of chemotherapy in breast cancer was launched and it implies dose-densification of chemotherapy trough the use of sequential non cross-resistant single agents or regimens. The introduction of primary systemic chemotherapy (PST) improved the outcome of patients with locally advanced breast cancer (LABC). Simultaneous PST is the standard approach to patients with LABC nowadays. On the other hand, many studies using two most active cytotoxic drugs in primary breast cancer, anthracyclines and taxanes showed that sequential dose-dense single agent PST could be superior in terms of enhancing the rates of patients suitable for conservative surgery. In the light of this data, based on the results of the new clinical trials we will discuss merits and demerits of using sequential dose-dense single agent chemotherapy in LABC.

Until recently, the mainstay of treatment in the majority of hormone receptor (HR)-positive, human epidermal growth factor 2 receptor (HER2)-negative advanced breast cancer (ABC) has consisted of single-agent endocrine therapy (ET). However, as understanding of endocrine resistance has grown, newer targeted agents have come to the fore. Inhibition of cyclin-dependent kinase complexes 4 and 6 (CDK4/6) combined with ET has shown significant activity in HR+ HER2− ABC, with impressive results in terms of progression-free survival (PFS) when compared with ET alone. This review summarizes the seminal findings pertaining to CDK4/6 inhibition in this population, specifically focusing on abemaciclib, contrasted with palbociclib and ribociclib. Potential directions for future studies are discussed, as a way of addressing outstanding issues such as establishing optimal treatment sequencing and agent combinations, appropriate patient selection to derive maximal benefits, predictive biomarkers and the employment of CDK4/6 inhibition beyond the ABC setting.
