Breast Implant-Associated Lymphoma.

Background: There has been increasing evidence in recent years that breast implants can, in rare cases, be associated with the development of an anaplastic large-cell lymphoma (ALCL).

Methods: This review is based on relevant publications retrieved by a selective search in PubMed for articles that appeared from the time of the initial description of breast-implant-associated ALCL onward (1997 to January 2018), and by a further search in German nationwide databases.

Results: 516 pathologically confirmed cases of breast-implant-associated (BIA) ALCL were documented around the world until February 2018; seven of these arose in Germany and were reported to the Federal Institute for Drugs and Medical Devices (Bundesinstitut für Arzneimittel und Medizinprodukte, BfArM).

The Y-box binding protein YB-1 is associated with progressive disease and mediates survival and drug resistance in multiple myeloma.

Current knowledge about molecular mechanisms underlying disease progression and drug resistance in multiple myeloma (MM) is still limited. Here, we analyzed the potential pathogenetic role of the Y-box binding protein YB-1 in MM. YB-1 is a member of the cold-shock domain protein superfamily and involved in various cellular functions such as proliferation.
