P16 SSB-positive renal cell carcinoma and anti-PD1-induced Sjögren’s syndrome : a key to understand the link between immune-related adverse events and antitumoral activity?

BJMO - 2021, issue 3, march 2021

Dan Truc Nguyen , Stéphane Holbrecht , Soizic Garaud

Introduction: Immune checkpoint inhibitors (ICI) are becoming a cornerstone of therapies for many cancers. However, a new class of side effects has emerged, namely immune-related adverse events (irAEs). Many studies have suggested a potential relationship between irAEs and benefit of ICI, but little is known about the mechanisms underlying toxicity and antitumor efficacy.

Objective: Angiosarcoma (AS) is a rare, aggressive subtype of soft tissue sarcoma (STS). Treatment requires a multidisciplinary approach and should preferably be carried out in reference centers. We performed an in-depth analysis of patient characteristics, treatments and prognostic factors in patients (pts) with AS treated at the University Hospitals Leuven (Belgium).

P17 Efficacy of palliative metronomic chemotherapy: A retrospective analysis of the 15 years experience at CHU UCL Namur site Godinne

BJMO - 2021, issue 3, march 2021

Catherine Percy , Géraldine Rosier , Claire Barani , Fanny Collette , Laurence Faugeras , Lionel D'Hondt

Background: Metronomic chemotherapy consists of low-dose oral chemotherapy given continuously. The antitumor activity is supposed to be due to antiangiogenic and immunomodulation effects. This retrospective analysis was done to evaluate the benefit-risk balance of this treatment in palliative setting for unselected metastatic cancer patients.

Treatment algorithm ER positive HER2 negative Advanced Breast Cancer

BJMO - 2019, issue 2, february 2019

Guy Jerusalem

After the major advances seen in the field of HER2 positive disease, fortunately, we have now also much more treatment options available for estrogen receptor positive HER2 negative advanced breast cancer. The better understanding of the mechanisms of resistance to endocrine therapy has allowed a much more rational treatment approach. Chemotherapy is only the preferred treatment option for patients with extensive symptomatic visceral disease. Almost all of our patients receive now an endocrine therapy based approach for several lines of treatment for advanced breast cancer. As endocrine therapy alone is not highly effective most of our patients are good candidates for combined therapy approaches with targeted agents. In the frst-line setting for advanced disease, the CDK4/6 inhibitors are now the targeted agents of choice because of the excellent safety profle in addition to the rapid and pronounced antitumoral effect. Nevertheless, many questions remain unanswered today. How should we treat specific subgroups of patients such as older patients, patients with some co-morbidities, patients with visceral disease or patients presenting bone only disease? Are biomarkers available to select the most appropriate treatments? Is progression-free survival a valid endpoint of clinical trials or do we need overall survival data? What is the optimal sequence? Should we use the best drugs frst? What should be the next line therapy in this case? During my presentation I will summarize the data available today and give you my personal view concerning these questions.
