The European Society for Medical Oncology Magnitude of Clinical Benefit Scale (ESMO-MCBS) in daily practice: A real-life feasibility analysis at the Medical University Vienna.
e18151 Background: The ESMO-MCBS constitutes a new tool to quantify the clinical benefit that may be anticipated from a novel anticancer treatment based on original data from randomized or controlled trials. In contrast to comparable concepts, this score appears somehow unique as it concentrates on the clinical benefit for the individual patient irrespective of socioeconomic factors. Being introduced 2015; the MCBS has excited great public interest in Europe in the last year. We present here the first feasibility analysis of the MCBS under real-life conditions at the Medical University Vienna (MUV), one of Europe’s largest centers. Methods: This study evaluated systematically the practicability of the MCBS for advanced/metastatic malignant diseases treated at the MUV ( > 15 tumor entities). A 3-step approach including data analysis of regimens in regular use, assessment of scores (1 = not recommended to 5 = highly recommended) and evaluation of results with a focus on clinical feasibility was applied. Results: In the majority of tumor entities and clinical settings the assessed MCBS scores were consistent with our daily practice and particularly with our 1st line standards for common tumors like metastatic breast-, colorectal- or lung cancer. However, there were certain limitations including orphan diseases with a lack of randomized data (e.g. rare sarcoma subtypes) or tumor entities with cascade like treatment settings (e.g. colorectal cancer). Interestingly, new immunomodulatory approaches and checkpoint inhibitors in particular, scored strikingly high in comparison to conventional chemo due to a favorable toxicity profile, positive influence on quality of life and strong efficacy data in many cases. A broad selection of data will be presented at the meeting. Conclusions: Our analysis encompasses a wide range of tumor entities and clinical settings and reflects the daily experience of a university clinic. Mostly, the MCBS scores supported treatment decisions based on the clinical benefit to be expected from a novel therapy and might also support socioeconomic questions exemplified by high scoring of immunomodulatory approaches.
