Abstract 2914


The ESMO-MCBS is a new tool to quantify the clinical benefit of a certain drug for the treatment of cancer. Recently, we have evaluated the practicability of the MCBS in daily practice of treating common tumor entities at our center. However, to date there is no experience of using the MCBS for rare tumors.


This study analyses the feasibility of the MCBS for rare tumor entities at the Clinical Division of Oncology, Medical University Vienna. We developed a 3-step approach to address this question. First, we retrospectively collected data to gain an overview on treatments in regular use. Second, we scored data with the MCBS, and third, evaluated results with the corresponding program directorships to assess the feasibility in a real-life context.


We assessed data on neuroendocrine tumors (NET), glioblastoma, sarcomas, thyroid-, pancreatic-, ovarian-, head/neck- and urothelial cancer. The following results were obtained: 1) NET and thyroid cancer: Recently published trials are comparable in design and efficacy and the MCBS scores are consistent with the clinical benefit seen in practice. However, the MCBS added little information on the question of optimal sequencing except for differentiated thyroid cancer where prior treatment (TKI or not) suggests an algorithm. 2) Pancreatic cancer: only two major 1st-line trials are currently available and a direct comparison is difficult due to diverging populations. 3) Sarcomas: MCBS reflects well the situation of GIST and was useful for randomized data on non-GIST sarcoma, but MCBS practicability was limited in rare subtypes due to a lack of controlled trials. 4) Ovarian cancer: the MCBS supports the use of bevacizumab in high-risk patients. This is in line with our experience. To date, there is only limited data for glioblastoma, head/neck- and urothelial cancer. However, if randomized trials were available, the MCBS-rating supported clinical decisions particularly for novel compounds. A broad selection of analyzed data will be presented at the meeting.


The MCBS is a helpful tool for clinical practice in rare tumors, if randomized data are available. It supports treatment decisions based on the expected clinical benefit.
