Unusual cause of severe anaemia in a patient with metastatic haemangiopericytoma
Haemangiopericytoma is a rare tumor of vascular origin. We report the case of patient with severe refractory anaemia due to peripheral destruction of red blood cells by spleen metastases. Anaemia was successfully treated by splenectomy. Afterwards, our patient developed liver and lung metastases and was treated, in a clinical trial, with gefitinib that stabilised the disease during nine years. These interesting features are discussed
BrainStorm: A brain metastases research platform to tackle the challenge of central nervous system (CNS) metastases in solid tumors (Oncodistinct 006).
International audienceTPS2066 Background: Better knowledge on the evolving epidemiology and biology of CNS metastases are key elements for the development of new treatment strategies and identification of promising therapeutic targets. A multidisciplinary Brain Metastases Clinical Research Platform called BrainStorm was launched by the Jules Bordet Institute and the Oncodistinct network. The BrainStorm program includes mainly patients with non-CNS metastatic solid tumors with high risk of developing CNS metastases allowing to build a large database focusing on three time periods: before the diagnosis of CNS metastases (Part A), at diagnosis (Part B) and after the diagnosis of CNS metastases (Part C). Methods: Subjects with newly diagnosed non-CNS metastases or up to 24 months from diagnosis of non-CNS metastases from triple-negative and HER2-positive breast cancer, lung cancer and melanoma are eligible for part A of the program. Subjects presenting with a 1st CNS event and not yet enrolled (previously mentioned cohorts and a cohort of other tumor types) can enter directly in parts B and subsequently part C of the study. Eligible subjects are followed for 48 months for relevant clinical data, neurological examinations, quality of life, survival status, and undergo examinations and samplings (Table 1). A total of 280 subjects (40 per cohort) with a 1st CNS event will be enrolled. The main objectives of the program are to collect clinical and biological data with the aim to identify risk factors for CNS metastases development (Part A) and to better understand the biology of CNS metastases (brain and leptomeningeal –Parts B and C) aiming to discover new targets for therapy and intensify the multidisciplinary approach for the management of CNS metastases from solid tumors. The translational part of the program will evaluate among others the use of cerebrospinal fluid circulating tumor DNA (CSF-ctDNA) as a surrogate for CNS metastases in order to characterize its molecular landscape. Currently, the study is recruiting in several sites within the Oncodistinct network. The data collected will help to develop innovative multidisciplinary research projects that could be implemented in all parts of the BrainStorm program. Clinical trial information: NCT04109131.

Avelumab as neoadjuvant therapy in patients with urothelial non-metastatic muscle invasive bladder cancer : a multicenter, randomized, non-comparative, phase II study (Oncodistinct 004-AURA trial)
Avelumab as neoadjuvant therapy in patients with urothelial non-metastatic muscle invasive bladder cancer: a multicenter, randomized, non-comparative, phase II study (Oncodistinct 004 - AURA trial).
INTRODUCTION: Cisplatin-based neoadjuvant chemotherapy (NAC) followed by surgery is the standard treatment for patients with non-metastatic muscle invasive bladder cancer (MIBC). Unfortunately, many patients are not candidates to receive cisplatin due to renal impairment. Additionally, no predictive biomarkers for pathological complete response (pCR) are currently validated in clinical practice. Studies evaluating immune checkpoint inhibitors in the peri-operative setting are emerging with promising results. Clinical trials are clearly required in the neoadjuvant setting in order to improve therapeutic strategies. METHODS AND ANALYSIS: Oncodistinct 004 - AURA is an ongoing multicenter phase II randomized trial assessing the efficacy and safety of avelumab single-agent or combined to different NAC regimens in patients with non-metastatic MIBC. Patients are enrolled in two distinct cohorts according to their eligibility to receive cisplatin-based NAC. In the cisplatin eligible cohort, patients are randomized in a 1:1 fashion to receive avelumab combined with cisplatin-gemcitabine or with dose-dense methotrexate-vinblastine-doxorubicin-cisplatin. In the cisplatin ineligible cohort, patients are randomized at a 1:1 ratio to paclitaxel-gemcitabine associated to avelumab or avelumab alone. Primary endpoint is pCR. Secondary endpoints are pathological response and safety. ETHICS AND DISSEMINATION: The study is approved by ethics committee from all participating centers. All participants provide informed consent prior inclusion to the study. Once completed, results will be published in peer-reviewed journals. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov (NCT03674424)
