Review Practice GuidelineNeoadjuvant systemic therapy in melanoma: recommendations of the International Neoadjuvant Melanoma Consortium.
Advances in the treatment of metastatic melanoma have improved responses and survival. However, many patients continue to experience resistance or toxicity to treatment, highlighting a crucial need to identify biomarkers and understand mechanisms of response and toxicity. Neoadjuvant therapy for regional metastases might improve operability and clinical outcomes over upfront surgery and adjuvant therapy, and has become an established role for drug development and biomarker discovery in other cancers (including locally advanced breast cancer, head and neck squamous cell carcinomas, gastroesophageal cancer, and anal cancer). ⋯ Neoadjuvant therapy is now an active area of research for melanoma with numerous completed and ongoing trials (since 2014) with disparate designs, endpoints, and analyses under investigation. We have, therefore, established the International Neoadjuvant Melanoma Consortium with experts in medical oncology, surgical oncology, pathology, radiation oncology, radiology, and translational research to develop recommendations for investigating neoadjuvant therapy in melanoma to align future trial designs and correlative analyses. Alignment and consistency of neoadjuvant trials will facilitate optimal data organisation for future regulatory review and strengthen translational research across the melanoma disease continuum.

Randomized Controlled TrialCediranib in patients with alveolar soft-part sarcoma (CASPS): a double-blind, placebo-controlled, randomised, phase 2 trial.
Alveolar soft-part sarcoma (ASPS) is a rare soft-tissue sarcoma that is unresponsive to chemotherapy. Cediranib, a tyrosine-kinase inhibitor, has shown substantial activity in ASPS in non-randomised studies. The Cediranib in Alveolar Soft Part Sarcoma (CASPS) study was designed to discriminate the effect of cediranib from the intrinsically indolent nature of ASPS. ⋯ Cancer Research UK and AstraZeneca.

Multicenter StudySelumetinib in paediatric patients with BRAF-aberrant or neurofibromatosis type 1-associated recurrent, refractory, or progressive low-grade glioma: a multicentre, phase 2 trial.
Paediatric low-grade glioma is the most common CNS tumour of childhood. Although overall survival is good, disease often recurs. No single universally accepted treatment exists for these patients; however, standard cytotoxic chemotherapies are generally used. We aimed to assess the activity of selumetinib, a MEK1/2 inhibitor, in these patients. ⋯ National Cancer Institute Cancer Therapy Evaluation Program, the American Lebanese Syrian Associated Charities, and AstraZeneca.

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.
