Randomized Controlled Trial Multicenter Study Comparative StudyComparison of MAPIE versus MAP in patients with a poor response to preoperative chemotherapy for newly diagnosed high-grade osteosarcoma (EURAMOS-1): an open-label, international, randomised controlled trial.
We designed the EURAMOS-1 trial to investigate whether intensified postoperative chemotherapy for patients whose tumour showed a poor response to preoperative chemotherapy (≥10% viable tumour) improved event-free survival in patients with high-grade osteosarcoma. ⋯ UK Medical Research Council, National Cancer Institute, European Science Foundation, St Anna Kinderkrebsforschung, Fonds National de la Recherche Scientifique, Fonds voor Wetenschappelijk Onderzoek-Vlaanderen, Parents Organization, Danish Medical Research Council, Academy of Finland, Deutsche Forschungsgemeinschaft, Deutsche Krebshilfe, Federal Ministry of Education and Research, Semmelweis Foundation, ZonMw (Council for Medical Research), Research Council of Norway, Scandinavian Sarcoma Group, Swiss Paediatric Oncology Group, Cancer Research UK, National Institute for Health Research, University College London Hospitals, and Biomedical Research Centre.

Randomized Controlled TrialFOLFIRI plus cetuximab versus FOLFIRI plus bevacizumab for metastatic colorectal cancer (FIRE-3): a post-hoc analysis of tumour dynamics in the final RAS wild-type subgroup of this randomised double-blind phase 3 trial.
FIRE-3 compared first-line 5-fluorouracil, leucovorin, and irinotecan (FOLFIRI) plus cetuximab with FOLFIRI plus bevacizumab in patients with KRAS exon 2 wild-type metastatic colorectal cancer. The same study also reported an exploratory analysis of a subgroup of patients with tumours that were wild-type at other RAS genes (KRAS and NRAS exons 2-4). We report here efficacy results for the FIRE-3 final RAS (KRAS/NRAS, exons 2-4) wild-type subgroup. Moreover, new metrics of tumour dynamics were explored during a centralised radiological review to investigate how FOLFIRI plus cetuximab conferred overall survival benefit in the absence of differences in investigator-assessed objective responses and progression-free survival. ⋯ Merck KGaA and Pfizer.

ReviewTreatment of low-risk ductal carcinoma in situ: is nothing better than something?
The heterogeneous nature of ductal carcinoma in situ has been emphasised by data for breast-cancer screening that show substantial increases in the detection of early-stage non-invasive breast cancer but no noteworthy change in the incidence of invasive and distant metastatic disease. Indolent non-progressive forms of ductal carcinoma in situ are managed according to similar surgical strategies as high-risk disease, with extent of resection dictated by radiological and pathological estimates of tumour dimensions. Although adjuvant treatments might be withheld for low-risk lesions, surgical treatments incur potential morbidity, especially when mastectomy and breast reconstruction are done for widespread low-grade or intermediate-grade ductal carcinoma in situ. ⋯ Changes include active surveillance for low-risk lesions and a watchful waiting policy with intervention when invasive local recurrence after breast-conserving surgery is detected. Prediction of ipsilateral invasive recurrence is likely to be improved by integration of molecular biomarkers with conventional histopathological parameters. Moreover, further genetic interrogation of ductal carcinoma in situ might lead to a reclassification of some low-grade lesions as non-cancerous entities.
