ReviewChanging frameworks in treatment sequencing of triple-negative and HER2-positive, early-stage breast cancers.
Important results are emerging from clinical trials showing that surgery followed by chemotherapy might not be the optimal strategy to maximise a patient's chance of survival from triple-negative or HER2-positive breast cancers. Administering chemotherapy before surgery provides an opportunity to directly observe the efficacy of a particular chemotherapy regimen. Patients who have extensive residual invasive cancer after neoadjuvant chemotherapy are at a high risk of recurrence for metastatic disease, which, in turn, make these patients ideal candidates for clinical trials. ⋯ The opportunity for residual-disease guided therapy, as observed in these trials, is lost when patients undergo surgery first. In this Personal View, we discuss the clinical implications of the CREATE-X and KATHERINE trials and place them into context with other developments in the adjuvant setting of early-stage breast cancer. We suggest that neoadjuvant systemic therapy should be considered as the new standard of care for HER2-positive and oestrogen receptor negative breast cancer, even for patients who present with operable (T1 or T2) disease.

Global childhood cancer survival estimates and priority-setting: a simulation-based analysis.
Accurate childhood cancer survival estimates are crucial for policy makers and clinicians for priority-setting and planning decisions. However, observed survival estimates are lacking for many countries, and when available, wide variation in outcomes is reported. Understanding the barriers to optimising survival can help improve childhood cancer outcomes. We aimed to provide estimates of global childhood cancer survival, accounting for the impact of multiple factors that affect cancer outcomes in children. ⋯ Boston Children's Hospital, Dana-Farber Cancer Institute, Harvard TH Chan School of Public Health, Harvard Medical School, National Cancer Institute, SickKids, St Jude Children's Research Hospital, Union for International Cancer Control, Children with Cancer UK Davidson and O'Gorman Fellowship.

Polatuzumab vedotin in combination with immunochemotherapy in patients with previously untreated diffuse large B-cell lymphoma: an open-label, non-randomised, phase 1b-2 study.
Polatuzumab vedotin, an antibody-drug conjugate targeting the CD79b component of the B-cell receptor, has demonstrated activity as a single agent and in combination with rituximab in relapsed or refractory diffuse large B-cell lymphoma. In this study, we evaluated the safety and preliminary activity of polatuzumab vedotin in combination with rituximab or obinutuzumab and cyclophosphamide, doxorubicin, and prednisone (CHP) in patients with previously untreated diffuse large B-cell lymphoma. ⋯ F Hoffmann-La Roche/Genentech.
