The impact of bone marrow fibrosis and JAK2 expression on clinical outcomes in patients with newly diagnosed multiple myeloma treated with immunomodulatory agents and/or proteasome inhibitors

We determined the impact of bone marrow fibrosis (BMF) on the clinical outcomes of newly diagnosed multiple myeloma patients in the current era of myeloma therapy. We found that BMF is common in myeloma and MM patients with BMF (particularly those with extensive BMF) have a poorer prognosis even when treated with immunomodulatory agents and proteasome inhibitors. AbstractWe determined the impact of bone marrow fibrosis (BMF) on the clinical outcomes of newly diagnosed multiple myeloma (NDMM) patients in the current era of myeloma therapy. A total of 393 MM patients were included in the final analysis. The median followup was 83  months (range: 3.9 to 212 months). BMF was noted in 122 (48.2%) evaluable patients. Median progression free survival (PFS) in patients without BMF was 30.2 (95% CI: 24.7‐38.0) months, and 21.1 (95% CI: 18.8‐27.5) months in patients with BMF present (P = .024). Median overall survival (OS) was 61.2 (95% CI: 51.5‐81.2) months in patients without BMF, and 45.1 (95% CI: 38.7‐57.0) months in patients with BMF (P = .0048). A subset of 99 patients had their bone marrow biopsies stained for JAK1 and JAK2 by immunohistochemistry. Of these samples 67 (67.7%) patients had detectable JAK2 expression predominantly noted on bone marrow megakaryocytes. JAK2 expression correlated with myeloma disease stage (P = .0071). Our study represents the largest dataset to date examining the association of BMF with prognosis in th...

There is persistent racial disparities in survival among patients with Diffuse Large B Cell Lymphoma. We conducted a cohort study of 181 patients for 10 years in a single community-based inner-city cancer center. Blacks had decreased overall survival compared to non-Blacks even after excluding patients with HIV and who did not receive chemotherapy. R-IPI score alone could not predict worse outcomes and increased mortality in Blacks with DLBCL.

Conclusions Although the laboratory information system’s contribution to the completeness of Cancer Registry incident cases was modest, it is useful to add laboratory data to routine cancer registry information flows due to the increasing use of molecular characterisation and to the phenomenon of dehospitalisation.

Colon perforations are rare in MM and here we report characteristics and clinical outcomes of 30 patients that were treated at Mayo Clinic. We believe that steroids are the precipitating factor. AbstractGastrointestinal complications of multiple myeloma (MM) treatment are common and include nausea, constipation, and diarrhea. However, acute gastrointestinal events like perforations are rare. We aimed to describe the characteristics and outcomes of patients with MM that had colonic perforations during their treatment. This is a retrospective study that included patients from all three Mayo Clinic sites who had MM and develo...

Meletios A. Dimopoulos Due to increased immunoglobulin production and uncontrolled proliferation, multiple myeloma (MM) plasma cells develop a phenotype of deregulated unfolded protein response (UPR). The eIF2-alpha kinase 3 [EIF2αK3, protein kinase R (PKR)-like ER kinase (PERK)], the third known sensor of endoplasmic reticulum (ER) stress, is a serine-threonine kinase and, like the other two UPR-related proteins, i.e., IRE1 and ATF6, it is bound to the ER membrane. MM, like other tumors showing uncontrolled protein secretion, is highly dependent to UPR for survival; thus, inhibition of PERK can be an effect...

ar SK Abstract BACKGROUND: Rearrangements involving the MYC protooncogene are common in newly diagnosed multiple myeloma (MM), but their prognostic significance is still unclear. The purpose of this study was to assess the impact of MYC rearrangement on clinical characteristics, treatment response, and survival in newly diagnosed MM. PATIENTS AND METHODS: This is a retrospective study including 1342 patients seen in Mayo Clinic in Rochester, MN, from January 2006 to January 2018, and who had cytogenetic testing by fluorescence in-situ hybridization at diagnosis, including MYC testing using the break apart FIS...
