This combination has led to surprisingly prolonged progression-free survival rates, along with possible cure in a subset of patients. In addition, early-phase single-arm trials are also showing deep and durable responses in relapsed patients when lenalidomide is combined with the novel agents ibrutinib and venetoclax. Although these drugs have limited single-agent activity in DLBCL, their pronounced activity in combination suggests a possible unique synergistic effect. Overall, recent studies suggest that lenalidomide will continue to be an active player in the treatment for DLBCL but likely in combination with other novel agents rather than in combination with chemotherapy.Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer for which chemotherapy had been the only active treatment option once metastatic disease developed. Immune checkpoint inhibitors (ICIs) are now available to treat patients with advanced TNBC who have programmed cell death ligand 1 (PD-L1)-positive tumors; these agents have been shown to improve clinical outcomes. Additionally, long-term disease control can be achieved in a subset of patients. Continued investigations of ICIs and optimal combinations with chemotherapy and targeted agents to enhance the immune response are ongoing, along with studies aimed at identifying the patients most likely to benefit. For early-stage TNBC, the data to date on administering ICI-based combination therapies in the neoadjuvant setting are compelling and suggest that the benefit from immunotherapy does not depend on PD-L1 expression. This review will discuss the clinical trial data on ICIs as monotherapy and in combination with chemotherapy in the treatment of patients with metastatic and early-stage TNBC.In the vast majority of cases, cutaneous melanoma presents as localized disease and is treated with wide excision and sentinel lymph node biopsy, with shared decision making regarding completion lymph node dissection and adjuvant systemic therapy. The treatment of recurrent and in-transit disease is more complex, with further options for regional and systemic therapies and multiple variables to be factored into decisions. Rates of overall and complete response to regional therapies can be quite high in carefully chosen patients, which limits the need for systemic therapies and their inherent side effects. Ongoing trials aim to assess the efficacy of combination regional and systemic therapies and assist in deciding among these options. This review discusses the treatment of primary melanoma and regional nodal disease and offers an in-depth discussion of options for the treatment of recurrent melanoma and in-transit melanoma.The androgen signaling axis has been the main therapeutic target in the management of advanced prostate cancer for several decades. Over the past years, significant advances have been made in terms of a better understanding the androgen receptor (AR) pathway and mechanisms of castration resistance, along with the development of more potent AR-targeted therapies. Catechin hydrate in vitro New drugs, such as abiraterone, enzalutamide, apalutamide, and darolutamide, have been approved for castration-resistant prostate cancer and also have demonstrated an overall survival benefit in the castration-sensitive state. Despite these major advances, the majority of patients eventually present with disease progression and a rise in prostate-specific antigen, reflecting a continuous dependence of disease on the AR pathway. In this setting, a number of AR-related mechanisms of resistance have been described, and novel strategies to overcome them are an important unmet need. In this manuscript, we review the most promising strategies to target the AR pathway in prostate cancer, including bromodomain and extraterminal (BET)/bromodomain inhibitors, CREB-binding protein/p300 inhibitors, N-terminal domain inhibitors, proteolysis-targeting chimeras, and AR-targeting vaccines. Another interesting and disruptive approach to targeting the AR and potentially reversing resistance to second-generation AR antagonists is the cyclic administration of high-dose testosterone, known as bipolar androgen therapy, which is currently being explored in multiple ongoing trials.
Approaches to the synthesis of qualitative research have existed for more than 20 years and have evolved significantly during that time. One common approach is meta-aggregation, as advocated by JBI. There is now a considerable number of published reviews that claim to follow the JBI approach to meta-aggregation. This methodological review sought to determine the extent to which a selection of these reviews follow the available guidance, with a view to establishing compliance and identifying potential areas for improvement.
The JBI Database of Systematic Reviews and Implementation Reports (JBISRIR) was searched from 2015 to 2017 to identify all qualitative systematic reviews following the JBI approach. Citations were screened by two independent reviewers, and data extraction was conducted independently by at least two reviewers. Eligible reviews were then assessed against the JBI methodological guidance and ENTREQ statement to determine compliance.
From the search, 33 health care-related reviews that met the inclusion criteria were identified. Several areas were identified where reviewers consistently made errors or did not clearly report their findings, including study screening and selection issues (particularly how this was done and by whom), transparent rationale for study exclusion, who performed data extraction and how, processes for developing synthesized findings, and the development and presentation of recommendations.
Although qualitative synthesis has come a long way, there are still some areas for improvement in conduct and reporting. This has implications for those who develop guidance and provide education to systematic reviewers.
