What are the lessons learned from 2015 in cardiology? In 2015, the European Society of Cardiology published new guidelines. This article sought to review the guidelines' key points as regards bacterial endocarditis and management of non-STEMI acute coronary syndrome. Like each year, numerous pharmacological studies were published. Among these, the Sprint Study certainly represents a milestone in the treatment of hypertension. Moreover, new therapeutic agents are emerging in the field of heart failure, as evidenced by the Paradigm and Socrates studies.

Cancer management has become multidisciplinary, and major advances have been achieved in medical oncology field over the last years. The year 2015 was marked by a change in the treatment strategies for metastatic prostate cancer, with docetaxel-based chemotherapy being now initiated concurrently with castration. This allows for a 10-month increase in median overall survival in these patients, thereby representing a major breakthrough. Last year, a new kind of targeted agent, olaparib, was also granted reimbursement for the treatment of platinumsensitive ovarian cancer. This inhibitor of PARP, a major protein involved in DNA repair, was shown to significantly increase recurrence-free survival in BRCA-mutated ovarian cancer patients. BRCA is a key protein involved in the second DNA repair mechanism. Lastly, the most impressive oncological advance achieved last year pertained to the introduction in daily practice of the anti-PD1 or PDL1 antibodies. Several studies, conducted mostly in melanoma patients, have shown this immunotherapy to be highly effective, with possible cancer cure for some patients. Administering these antibodies is, however, associated with very specific toxicity features, namely autoimmune toxicity that may be severe or even fatal if not recognized and treated early. All these treatments are available at the King Albert II Cancer Institute.

Spondyloarthritis (Spa) is a chronic immune-mediated inflammatory disease characterized by skeletal involvement (axial, an peripheral or both), at times associated with extra-articular manifestations (skin, gut, or eye). This heterogenic rheumatic disease may cause structural and functional impairments, in addition to a decrease in patients' quality of life. A better understanding of the disease's pathophysiology has led to new encouraging therapeutics strategies for managing this disease.

Over the last years, the management of rheumatoid arthritis (RA) has been largely improved owing to the introduction of biologicals. These agents have been developed based on a better understanding of the disease pathophysiology. In the next years, the histopathological and molecular features of the synovial tissue will likely help clinicians better define RA treatment strategies.
