Cutaneous amyloidosis as the first presentation of Waldenstrom macroglobulinemia

Background: Waldenstrom macroglobulinemia is a lymphoplasmacytic lymphoma with elevated serum immunoglobulin M and multi-organ involvement. Primary systemic amyloidosis usually develops due to immunoglobulin light chains depositions in different organs due to an underlying gammopathy. Case presentation: Our patient was an 86-year-old man with macroglossia, ecchymotic patches and bullous lesion...

Cancer Therapy: Preclinical Carfilzomib-Dependent Selective Inhibition of the Chymotrypsin-like Activity of the Proteasome Leads to Antitumor Activity in Waldenstrom's Macroglobulinemia

Purpose: Primary Waldenstrom’s Macroglobulinemia (WM) cells present with a significantly higher level of the immunoproteasome compared with the constitutive proteasome. It has been demonstrated that selective inhibition of the chymotrypsin-like (CT-L) activity of constitutive-(c20S) and immuno-(i20S) proteasome represents a valid strategy to induce antineoplastic effect in hematologic tumors. W...

Src tyrosine kinase regulates adhesion and chemotaxis in Waldenstrom macroglobulinemia.

PURPOSE Waldenstrom macroglobulinemia is a lymphoplasmacytic lymphoma characterized by widespread involvement of the bone marrow. Despite different options of therapy, Waldenstrom macroglobulinemia is still incurable. Src tyrosine kinase has been shown to play a central role in the regulation of a variety of biological processes, such as cell proliferation, migration, adhesion, and survival in ...

Mechanisms of activity of the TORC1 inhibitor everolimus in Waldenstrom macroglobulinemia.

PURPOSE The TORC1 inhibitor everolimus has previously shown significant activity as a single agent in hematologic malignancies, with reported responses of 30% to 70% in Waldenstrom macroglobulinemia. However, the specific mechanisms by which this class of mTOR inhibitors exerts anti-Waldenstrom macroglobulinemia activity have not been fully investigated. We therefore sought to dissect the mecha...
