Multiple myeloma (MM) accounts for about 1.8% of all cancers and slightly over 17% of hematologic malignancies. Despite improvements in outcomes in recent years, currently, there is still no cure for this disease. Although allogeneic stem cell transplantation (Allo-SCT) is a potentially curative treatment, given the armamentarium of highly effective therapeutic options and a pipeline of novel agents, many opinion leaders sustain that there is no longer a role for this approach. ⋯ However, there are no current data supporting upfront Allo-SCT. Prospective trials combining the so-called "graft-versus-myeloma" effect and new drugs are an unmet medical need in high-risk patients. Early relapse after first-line treatment, which identifies patients with poor prognosis independently of other prognostic factors, could become a clinical indication.

While the outcome of patients with multiple myeloma has significantly improved over the last two decades, the disease remains incurable for the majority of patients. With the advent of novel agents, there has been a shift towards prolonged therapy as opposed to fixed-duration therapy, aimed at improving progression-free survival and overall survival. Evidence favoring continuous therapy has emerged over the last 2 decades and in the context of maintenance after proteasome inhibitor plus immunomodulatory drug induction followed by high dose melphalan and stem cell transplantation, this leads to >80% overall survival at 5 years. ⋯ As the survival improves, it is crucial to identify patients who are projected to have better survival and spare them toxicities arising from indefinite maintenance therapy. The role of minimal residual disease in this context is being investigated in numerous clinical trials and in the next few years the goal should be to use this in a rational way to achieve the ability to identify patients who would require continuation or escalation of therapy to improve their projected survival as well as to identify the group of patients in whom maintenance therapy could perhaps be time-limited without compromising their survival. Here we review the evidence for maintenance therapy from the key trials in the past years, present an overview of the current landscape and our perspective of maintenance therapy in the future.

Strong epidemiologic evidence has highlighted the role of pollution, on top of adverse climate features, as a novel cardiovascular risk factor. However, mechanistic proof that reducing pollution may be beneficial to prevent atherothrombotic events is limited. We aimed at appraising the impact of temporary traffic bans in a large metropolitan area on the risk of acute coronary syndromes. ⋯ Temporary traffic ban may favorably reduce coronary atherothrombotic events, and in particular NSTEMI, even if not globally and immediately impacting on environmental pollution. Further controlled studies are required to confirm and expand this hypothesis-generating results.
