- The 15th St. Gallen International Breast Cancer Conference 2017 in Vienna, Austria reviewed substantial new evidence on loco-regional and systemic therapies for early breast cancer. Treatments were assessed in light of their intensity, duration and side-effects, seeking where appropriate to escalate or de-escalate therapies based on likely benefits as predicted by tumor stage and tumor biology. The Panel favored several interventions that may reduce surgical morbidity, including acceptance of 2 mm margins for DCIS, the resection of residual cancer (but not baseline extent of cancer) in women undergoing neoadjuvant therapy, acceptance of sentinel node biopsy following neoadjuvant treatment of many patients, and the preference for neoadjuvant therapy in HER2 positive and triple-negative, stage II and III breast cancer. The Panel favored escalating radiation therapy with regional nodal irradiation in high-risk patients, while encouraging omission of boost in low-risk patients. The Panel endorsed gene expression signatures that permit avoidance of chemotherapy in many patients with ER positive breast cancer. For women with higher risk tumors, the Panel escalated recommendations for adjuvant endocrine treatment to include ovarian suppression in premenopausal women, and extended therapy for postmenopausal women. However, low-risk patients can avoid these treatments. Finally, the Panel recommended bisphosphonate use in postmenopausal women to prevent breast cancer recurrence. The Panel recognized that recommendations are not intended for all patients, but rather to address the clinical needs of the majority of common presentations. Individualization of adjuvant therapy means adjusting to the tumor characteristics, patient comorbidities and preferences, and managing constraints of treatment cost and access that may affect care in both the developed and developing world.

- In this implementation phase of the European Cancer Patient's Bill of Rights (BoR), we confirm the following three patient-centred principles that underpin this initiative: 1. The right of every European citizen to receive the most accurate information and to be proactively involved in his/her care. 2. The right of every European citizen to optimal and timely access to a diagnosis and to appropriate specialised care, underpinned by research and innovation. 3. The right of every European citizen to receive care in health systems that ensure the best possible cancer prevention, the earliest possible diagnosis of their cancer, improved outcomes, patient rehabilitation, best quality of life and affordable health care. Agree our high-level goal. The vision of 70% longterm survival for patients with cancer in 2035, promoting cancer prevention and cancer control and the associated progress in ensuring good patient experience and quality of life. Establish the major mechanisms to underpin its delivery. (1) The systematic and rigorous sharing of best practice between and across European cancer healthcare systems and (2) the active promotion of Research and Innovation focused on improving outcomes; (3) Improving access to new and established cancer care by sharing best practice in the development, approval, procurement and reimbursement of cancer diagnostic tests and treatments. Work with other organisations to bring into being a Europe based centre that will (1) systematically identify, evaluate and validate and disseminate best practice in cancer management for the different countries and regions and (2) promote Research and Innovation and its translation to maximise its impact to improve outcomes.

- Pathological complete response (pCR) following chemotherapy is strongly associated with both breast cancer subtype and long-term survival. Within a phase III neoadjuvant chemotherapy trial, we sought to determine whether the prognostic implications of pCR, TP53 status and treatment arm (taxane versus non-taxane) differed between intrinsic subtypes. Patients were randomized to receive either six cycles of anthracycline-based chemotherapy or three cycles of docetaxel then three cycles of eprirubicin/docetaxel (T-ET). pCR was defined as no evidence of residual invasive cancer (or very few scattered tumour cells) in primary tumour and lymph nodes. We used a simplified intrinsic subtypes classification, as suggested by the 2011 St Gallen consensus. Interactions between pCR, TP53 status, treatment arm and intrinsic subtype on event-free survival (EFS), distant metastasis-free survival (DMFS) and overall survival (OS) were studied using a landmark and a two-step approach multivariate analyses. Sufficient data for pCR analyses were available in 1212 (65%) of 1856 patients randomized. pCR occurred in 222 of 1212 (18%) patients: 37 of 496 (7.5%) luminal A, 22 of 147 (15%) luminal B/HER2 negative, 51 of 230 (22%) luminal B/HER2 positive, 43 of 118 (36%) HER2 positive/non-luminal, 69 of 221(31%) triple negative (TN). The prognostic effect of pCR on EFS did not differ between subtypes and was an independent predictor for better EFS [hazard ratio (HR) = 0.40, P < 0.001 in favour of pCR], DMFS (HR = 0.32, P < 0.001) and OS (HR = 0.32, P < 0.001). Chemotherapy arm was an independent predictor only for EFS (HR = 0.73, P = 0.004 in favour of T-ET). The interaction between TP53, intrinsic subtypes and survival outcomes only approached statistical significance for EFS (P = 0.1). pCR is an independent predictor of favourable clinical outcomes in all molecular subtypes in a two-step multivariate analysis.

- LBA503 Background: Predictive markers of response to chemotherapy are lacking. Preclinical data suggest that p53 mutated tumors are resistant to anthracyclines and sensitive to taxanes. However, clinical data are contradictory. Using a functional yeast assay to detect biologically important mutations, this study tested the hypothesis that docetaxel confers a greater advantage over anthracyclines in p53 mutated tumors (mut) than p53 wild type (wt). Methods: Patients (pts) with locally advanced/inflammatory or large operable tumors were randomized to either a standard anthracycline regimen (arm A) or a taxane-based treatment (arm B). In arm A pts received 6 cycles of FEC 100, or tailored FEC + G-CSF (Swedish cohort). In arm B docetaxel (T) 100mg/m2 was given for 3 cycles, followed by 3 cycles of epirubicin 90mg/m2and T 75mg/m2 q3 weeks (T-ET). After chemotherapy, pts underwent surgery followed by radiotherapy. Endocrine therapy and/or trastuzumab were given according to each center's policy. Fresh frozen tumor biopsies were mandatory before starting chemotherapy: frozen sections were examined centrally and the p53 test was done when the invasive tumor cell content was > 20%. cDNA derived from tumor-extracted RNA was transfected into yeast (Flaman et al. PNAS 1995): tumors were deemed p53 wt when there were < 20% red colonies (background) and p53 mut > 20%. The three co-primary comparisons for the endpoint of progression-free survival (PFS) were between arms A and B in p53 mut, p53 wt, and the entire trial population, each at a p=0.02. The sample size gave sufficient power for an interaction test for outcomes between p53 mut and wt at p<0.05. Results: From April 2001 to November 2006, 1,856 patients were included. A total of 386 pts (21%) were ineligible (including 292 pts with <20% tumor cells and 67 without sample). No unexpected toxicity was observed. At the time of analysis 675 events were registered after a median follow-up time of 57 months. The results are summarized below. Conclusions: p53 is not a predictive factor of response or resistance to taxanes, although it is, as expected, prognostic (<0.001). PFS is not statistically significantly different between FEC and T-ET arms at the 2% cutoff level. [Table: see text] [Table: see text]
