TPS667 Background: The benefit of adjuvant chemotherapy (CT) is highly controversial for elderly breast cancer (BC) women presenting with an oestrogen receptor-positive (ER+) HER2-negative (HER2-) phenotype. Conversely to hormonal treatment (HT) that remains the cornerstone of adjuvant treatment for such luminal tumours, CT may severely decompensate comorbidities and alter quality of life in elderly patients. As disappointing as it is in drug development, elderly have been constantly excluded from trials evaluating new modern prognosis classifiers. This prospective multicentre trial funded by a French national grant (PHRC 2011) is the first phase III trial to investigate the impact on overall survival (OS) of adjuvant CT in elderly ER+ HER2- BC patients selected with a modern prognosis classifier and taking into account competing risks for mortality (EudraCT 2011-004744-22). Methods: Following surgery, 2,000 women 70+ with ER+ HER2- BC (any pT/pN), will have a genomic grade (GG, derived from frozen MapQuantDx™, Ipsogen) centrally assessed on formalin-fixed paraffin-embedded samples. Only those with a high GG (estimation~700) will be randomized between HT alone vs CT followed by HT. CT regimen is left to the choice of investigators amongst 3 regimen of same duration [4 q3w cycles, docetaxel+cyclophosphamide, doxorubicin or non pegylated liposomal doxorubicin (Myocet)+cyclophosphamide, all with G-CSF], as well as HT (aromatase inhibitor±tamoxifen). Those with low GG or not included for other reasons (estimation~1,300) will be followed as an observational parallel cohort with HT alone. Sample size is based on 4-year OS as primary endpoint (87.5 vs 80%), bilateral α=0.05, β=0.20 and HR= 0.60. Secondary endpoints include assessment of competing risks for mortality, cost-effectiveness and Q-TWiST analysis, geriatric items (e.g. Lee’s 4-year mortality score and G8 screening tool), acceptability, quality of life (QLQ-C30 and specific elderly scale ELD15), and translational research on ageing/prognostic biomarkers and pharmacogenetic. The trial has been just opened to inclusion in February 2012.

The GPs' strike and the terrorist attacks did not impact our call centre's activity in the same manner. The strike increased the number of PMFs without increasing the number of calls received. The attacks increased the number of calls received and MICU dispatched without increasing the number of PMFs. Many markers are at the disposal of call centres to evaluate the impact of healthcare events.
