Dear Editor, Multiple myeloma is a subgroup of plasma cell dyscrasias with neoplastic proliferation of plasma cells or their precursors. Crystalline keratopathy is a well-recognised but rare ocular manifestation of multiple myeloma.1 We present a rare case of IgG-lambda multiple myeloma that manifested as polychromatic crystals in the cornea—a presentation that has not been previously described...

Several reports have demonstrated associations between scleroderma and cancer and between multiple myeloma and autoimmune diseases. Few papers have also reported the concurrence of scleroderma and multiple myeloma. We report a case of multiple myeloma that developed in a male patient after 28 years of fulfilling a diagnosis of scleroderma. The main presenting feature of multiple myeloma was asc...

Human multiple myeloma is a presently incurable hematologic malignancy, and novel biologically based therapies are urgently needed. GCS-100 is a polysaccharide derived from citrus pectin in clinical development for the treatment of cancer. Here we show that GCS-100 induces apoptosis in various multiple myeloma cell lines, including those resistant to dexamethasone, melphalan, or doxorubicin. Ex...

Infections are a major cause of morbidity and mortality in patients with multiple myeloma. To estimate the risk of bacterial and viral infections in multiple myeloma patients, we used population-based data from Sweden to identify all multiple myeloma patients (n=9253) diagnosed from 1988 to 2004 with follow up to 2007 and 34,931 matched controls. Cox proportional hazard models were used to esti...

Multiple myeloma is a plasma cell malignancy characterized by marked heterogeneous genomic instability including frequent genetic alterations in epigenetic enzymes. In particular, the histone methyltransferase Enhancer of Zeste Homolog 2 (EZH2) is overexpressed in multiple myeloma. EZH2 is the catalytic component of the polycomb repressive complex 2 (PRC2), a master transcriptional regulator of...

Many agents are active in multiple myeloma, but the majority of patients relapse. This clinical pattern suggests most cancer cells are eliminated, but cells with the clonogenic potential to mediate tumor regrowth are relatively chemoresistant. Our previous data suggested that CD138(+) multiple myeloma plasma cells cannot undergo long-term proliferation but rather arise from clonogenic CD138(neg...

Patients diagnosed with multiple myeloma are living longer because of new therapeutic options. Helping patients with multiple myeloma maintain a good state of health from the time of diagnosis and throughout their therapy leads to better quality of life. However, patients with multiple myeloma are at risk for illnesses experienced by the general population and at additional risk for illnesses r...

PURPOSE Multiple myeloma remains an incurable disease. New approaches to develop better tools for improving patient prognostication and monitoring treatment efficacy are very much needed. In this study, we aimed to evaluate the potential of metabolomics by (1)H-NMR to provide information on metabolic profiles that could be useful in the management of multiple myeloma. EXPERIMENTAL DESIGN Seru...

Purpose: We have previously demonstrated that ritonavir targeting of glycolysis is growth inhibitory and cytotoxic in a subset of multiple myeloma cells. In this study, our objective was to investigate themetabolic basis of resistance to ritonavir and todetermine the utility of cotreatment with the mitochondrial complex I inhibitor metformin to target compensatory metabolism. Experimental Desig...
