Abstract PURPOSE We compared multiple response assessment and visualization techniques for characterization of post-SRS treatment outcomes in a cohort of breast cancer patients with long median follow-up. METHODS A retrospective IRB-approved review was completed of 75 breast cancer patients treated with SRS for 271 brain metastases with median follow up of 40 months. Tumor dimensions, brain failure events, corticosteroid use, and clinical status were analyzed utilizing RANO-BM, bidimensional product (BDP), and bidimensional sum (BDS) techniques. 46/75 patients were eligible for RANO-BM assessment. Response at each post-treatment assessment were scored as PD, SD, PR, or CR, and the concordance between techniques was determined. A scoring system-based outcome metric labelled ‘average state’ was derived to estimate fractional time/response state by each assessment method. Interactive timeline displays of outcome states were generated. RESULTS The concordance of patient response states was determined using either RANO-BM, BDP or BDS among the 46 eligible patients. The overall mean and median concordance between techniques were 0.82 and 0.83, (range 0.52 – 1). The average state for the patient population post-treatment was 1.98 by RANO-BM, 2.29 by BDP, and 2.19 by BDS. For patients excluded from RANO-BM secondary to lack of measurable disease, the average state was determined to be 2.44 by BDP and 2.35 by BDS. The average state for HER2+ vs. HER2- patients was 2.21 vs. 1.75 by RANO-BM, 2.58 vs. 2 by BDP, and 2.39 vs. 1.99 by BDS. An interactive timeline view was generated to display outcome states utilizing the 3 response assessment techniques, and the impact of inclusion of non-target lesions and variable response parameters was assessed graphically. CONCLUSIONS These results characterize the concordance and the limitations of multiple outcome assessment methodologies in a post-SRS cohort with long median follow-up. The utility of a novel ‘average state’ outcome metric is demonstrated in this cohort.

The impact of patient-related factors on the occurrence of febrile neutropenia in breast cancer patients receiving (neo-)adjuvant chemotherapy with 5-fluorouracil, epirubicin, and cyclofosfamide (FEC) x6 or FEC x3 followed by docetaxel (D) x3.

The Impact

1078 Background: Recently we described the impact of genetic variability on severe toxicity in breast cancer patients receiving (neo-) adjuvant FEC chemotherapy (Annals of Oncology 2013, In Press). We now further assessed the impact of a wide range of patient-related factors on FEC toxicity in routine clinical setting. Methods: Patients with early breast cancer receiving (neo-)adjuvant 6 cycles FEC or sequential 3 cycles of FEC and 3 cycles D were retrospectively evaluated through electronic chart review for febrile neutropenia (primary endpoint; CTC 3.0). Age at diagnosis, body mass index, body surface area, number of cycles received, germline genetic polymorphisms, and baseline biochemical variables (white blood cell count, absolute neutrophil count, platelets, aspartate aminotransferase, alanine aminotransferase, total bilirubin and creatinine) were available for most patients (missing data <10%). All patients had follow up for progression free survival (PFS) and overall survival (OS). Multivariate logistic regression analysis was performed including univariate associates of outcome with a p-value <0.25. Results: We identified 1,031 patients treated between 2000-2010 with 6x FEC (n=488) or 3x FEC followed by 3x D (n=543). 174 (16.9%) patients developed febrile neutropenia during FEC. After logistic regression analysis febrile neutropenia was found to be significantly associated with carriers of the rs45511401 variant T-allele in the MRP1 gene found in 12% of patients (p= 0.03, OR1.99, CI 1.07-3.71) and with increasing serum creatinine values (p=0.05 OR 4.58/CI 0.99-20.98); all other investigated patient-related parameters were not retained by the model. At a mean follow up of 5.2 years, the occurrence of febrile neutropenia was not correlated with PFS and OS. Conclusions: In this study, only the baseline level of serum creatinine and germline genetic polymorphisms in the MRP-1 gene were predictive for the occurrence of febrile neutropenia in patients receiving FEC chemotherapy. The occurrence of febrile neutropenia did not seem to impact on outcome.

48 Background: Electrochemotherapy (ECT) combines the administration of poorly permeable chemotherapeutic agents with electroporation. It has been shown to be effective when compared with other treatments. This study assessed how breast cancer patients were benefited and identified potential problems at a designated treatment centre. Methods: This was a single centre prospective study of patients with cutaneous metastases from breast cancer. Patients who fulfilled NICE UK (National Institute Of Clinical Excellence) and local guidelines were treated. Gabapentin was given prior to general anaesthesia. Intravenous Bleomycin 15,000IU/m2 was given as a bolus. Treatment was commenced 8 minutes later with Cliniporator. Electrical pulses were delivered via an electrode inserted through the skin surface. Treatment response, disease progression free duration, post-operative pain and length of in-patient stay (LOS) were recorded. Patients recorded a symptom diary post treatment. Results: 20 treatments were performed in 16 patients from 2011-2015 with 53 separate areas treated. 8 patients had diffuse lesions, 5 had discrete lesions and 3 had both diffuse and discrete areas. 16 patients were being treated with ECT for the first time and 4 patients required 2 treatments. Median LOS was 3 days. Median follow up was 6 months (range 3-12).12 patients had complete response (75%) and 4 patients partial response. There was no disease progression for 6 months or more in 9 patients (56%) and 2 further patients had disease stabilised for 3 months with systemic or cutaneous progression in the remaining patients in 3 months or less. There were no deaths or immediate adverse events from ECT. 5 Patients (31%) with extensive diffuse chest wall disease reported persistent discomfort post treatment requiring extended period of post treatment analgesia. Conclusions: Electrochemotherapy is safe and effective treatment for cutaneous metastases. Appropriate patient selection for treatment, pre-emptive analgesia, post treatment support and follow up is essential in order to maximise the benefits and minimise potential side-effects particularly in extensive chest wall disease.

5 Background: CanIMPACT is a multi-provincial Canadian research team funded to identify and address key issues faced by cancer patients and providers at the intersection of primary and specialist oncology care. Canada has national healthcare standards, but provincial/territorial healthcare delivery systems. One facet will use administrative data from the population-based, publicly-funded healthcare system to evaluate issues during pre-diagnosis, treatment, and post-treatment survivorship for breast cancer patients. For the survivorship phase, we aim to conduct the following analyses and compare across provinces: 1) Utilization of physician services overall and by specialty, including oncologists, non-oncology specialists, and primary care; 2) Assessment of adherence to ASCO and Canadian follow-up guideline for breast cancer care, use of surveillance breast imaging, and metastatic investigations; 3) Assessment of adherence to recommended care of chronic illness and preventive care; 4) Quantification of the cost of follow-up overall and by specialty; 5) Comparison of inter- and intra-provincial variation for all outcomes by health administrative region and for vulnerable groups (age ≥ 75 at diagnosis, northern/rural/remote, low income, immigrants), and examine the effect of continuity of primary care and chronic disease on post-treatment care. Methods: Patients will be identified from provincial cancer registries and linked to data extracted from: outpatient physician service claims, hospital inpatient and outpatient data, and cancer facility medical records. Results: Participating provinces have finalized the core questions and detailed protocols, and assessed data comparability. They are in the process of obtaining the required ethics and data access approvals, and data acquisition for processing and analysis. Conclusions: Results will address existing information gaps that can be used to improve transition and care across the cancer care trajectory. Importantly, results will be combined with those of a CanIMPACT qualitative study to inform design of a pragmatic randomized trial focused on improving coordination and quality of care.

The Impact

39 Background: The transitioning of well breast cancer patients, post-treatment, to family physicians is accepted as a safe and effective model of care. Numerous studies have focused on patients’ experience and health outcomes, but research has not examined the experience of oncologists who are practicing in this model of care. The purpose of this research is to explore the impact of a transition model of care on oncologists’ practice. Methods: Purposive sampling was employed to recruit and interview oncologists who have been transitioning patients to family physicians for two or more years. A total of 15 medical and radiation oncologists practicing in Ontario, Canada were interviewed. Data were analyzed using thematic analysis. Results: Most oncologists interviewed were confident that the transitioning of patients to family physicians is safe for many patients post-treatment. Despite some concerns about the feasibility of the model, namely acceptance of the model among patients and family physicians, oncologists perceived that the model enhances efficiency and sustainability of the cancer system. As the volume of patients in follow-up decreased, oncologists saw a variety of impacts including: a reduction in overbooking in their clinics; more new patients able to be seen in consultation each week; more flexibility in their schedules to accept urgent appointments; and an increased ability to spend more time with patients who are dealing with complex issues. For some oncologists, well patient appointments are a rewarding part of their work. Meanwhile, many experience challenges with increased intensity of workload. Oncologists recognize that some patients and family physicians may be reluctant but they believe that early communication with patients about eventual transition, and improved communication with family physicians can enhance the acceptability of this model of care. Conclusions: Oncologists interviewed in this study reported that the time they used to spend with well follow-up patients can now be spent on other activities that contribute to the enhancement of quality of care for cancer survivors and efficiency in the broader cancer system.

The Impact

The impact of ER levels on the response to tamoxifen was evaluated in 1,623 postmenopausal primary breast cancer patients treated at our center (median follow-up 8.2 years). In patients receiving adjuvant tamoxifen a significantly longer disease-free survival (DFS) was observed when ER levels were elevated (p<0.00001). Very high ER (>424 fmol/mg protein) appeared to be detrimental in node-negative patients not treated with tamoxifen.

The Impact

Over the last years, the incidence of brain metastases in HER2 breast cancer patients has increased. Surgery and radiotherapy are the current standard local therapies. Nevertheless, it is unclear which and when systemic treatment should be applied in addition to local treatment. This work aims to present an updated review of current systemic treatment options for patients with HER2+ metastatic breast cancer with brain metastases and to present a case study of clinical cases that occurred in a Portuguese population. The methodology of this work included a literature search in PubMed for the impact of HER2-targeting agents, such as pertuzumab, trastuzumab emtansine (T-DM1), lapatinib, neratinib, trastuzumab deruxtecan, and tucatinib in the treatment of patients with HER2+ breast cancer with brain metastases. Then, a cohort of Portuguese patients with HER2+ breast cancer (n=44) was analyzed. In this exploratory study, considering a follow-up of 23.9 months, three patients (6.8%) developed brain metastases despite having shown a complete pathological response. The role of systemic treatment for patients with HER2 breast cancer with brain metastases has rapidly evolved following recent successes in phase II and III clinical trials. The biggest challenge is how to integrate systemic and local treatment in the management of these patients.

10588 Background: 18F-FDG-PET is rapidly spreading “technology” in oncology. Its appropriate use and the clinical settings in which it can modify decision-making need to be defined. Methods: All the requests for 18F-FDG-PET issued by the Medical Oncology Unit are submitted to internal audit. The aim is to evaluate the impact of the information deriving from the test on the subsequent therapeutic strategy in breast cancer patients (pts). From July 2002 to July 2005, 195 18F-FDG-PET examinations were performed in 110 pts. Pt series have been subdivided according to disease stage or clinical setting: Group 1) NED during the follow-up 23 (11.8%); Group 2) suspected first recurrence 52 (26.7%) (included 20 cases with an isolated elevation of CA15.3 and/or CEA serum levels); Group 3) overt metastases: a) single lesion 10 (5.1%), b) multiple lesions with suspected disease progression 26 (13.3%), c) re-evaluation of non-progressive metastatic disease 84 (43.1%). Results: Overall, 18F-FDG-PET was positive in 112 (57.4%) cases: in Groups 1), 2), 3a), 3b) and 3c) positivity was 13%, 63.5%, 60%, 73.1% and 60.7%, respectively. As concerns those pts with an isolated marker serum level increase during the follow-up, 18F-FDG-PET was positive in 13 (65%) cases. Overall, the result of 18F-FDG-PET determined a therapeutic strategy change in 79 (40.5%) cases. This change consisted in a decision to start or re-start anti-tumor medical treatment in 46 (58.2%), to perform or exclude surgery or radiotherapy with a potentially radical purpose in 10 (12.7%), to continue follow-up or to stop treatment in 23 (29.1%). The change of strategy according to Groups 1), 2), 3a), 3b) and 3c) was 13%, 75%, 90%, 61.5% and 14.3%, respectively. Conclusions: A “clinical” approach to the use of 18F-FDG-PET in breast cancer pts allows us to change the decision-making in about 40% of pts. Clinical situations in which 18F-FDG-PET is more useful are in cases of suspected recurrence and oligometastatic disease. No significant financial relationships to disclose.

Cardiac Outcome

213 Background: Anthracyclines and anti-Her-2 targeted therapy are commonly used effective breast cancer treatments. They are known to decrease Left Ventricular Ejection Fraction (LVEF), which may increase patients’ morbidity and mortality. There is currently no consensus on post treatment cardiac follow-up. Recent observations suggested that ACEI and B blocker drugs could have cardioprotective effects. We conducted a retrospective study to assess patients’ cardiac outcome using post-treatment LVEF follow-up and effect of ACEI and B blocker on cardiac outcome for breast cancer patients who received cardiotoxic agents in our institution. Methods: We reviewed 155 charts of non-metastatic breast cancer patients between 2000-2008, who received anthracyclines and/or anti-Her-2 targeted therapy. Patients were stratified into groups A (anthracycline), B (trastuzumab) and C (anthracycline+trastuzumab). Results: Patients’ median age was 52.5 years. Six patients had coronary artery disease and 45 received radiation to the left breast. After a median follow-up of 93 months, only 3 of 155 (2%) patients developed symptoms of congestive heart failure. One hundred twenty patients had pre-treatment LVEF evaluation, while only 31 patients had pre and post LVEF evaluation. Mean LVEF difference was -7.89, - 9.01, -9 and -6.08 for all patients, group A, group B and group C, respectively. Thirty patients were on ACEI, 7 of them had LVEF follow-up with mean difference of -6.86. Thirty patients were on B blocker, 7 of them had LVEF follow-up with mean difference of -15. Because of the small size of the groups who had LVEF follow-up, no statistical difference can be detected. Conclusions: Our patient population showed very low incidence of clinically significant cardiac events in relation to anthracycline and anti-her-2 directed therapy after a median follow-up of 93 months. However, further follow is required to assess cardiac outcome that may affect quality of life and survival later in life. In this regard, our institution is establishing a dedicated cardio-oncology service to closely monitor patients who have been treated with cardiotoxic agents and provide early cardiac management if needed.
