Clinical and Pathological Characteristics of Non-AL Amyloidosis MGRS: A Single-Center Experience Over 10 Years.

Objective: Monoclonal gammopathy of renal significance (MGRS) is a heterogeneous and relatively recently defined disorder that encompasses many kidney and hematologic pathologies. MGRS remains a rare disease and there is a need for more literature regarding its treatment and outcomes. In this study, we share our center's experience with MGRS including incidence of different kidney pathologies, clone type, kidney and hematologic response, and progression-free survival.

A Prognostic Symptom Model Incorporating Patient-Reported Symptoms for Transplant-Ineligible Patients with Multiple Myeloma.

Introduction: Patients with transplant-ineligible (TIE) multiple myeloma (MM) have high rates of symptom burden. The aim of this study was to develop and validate a prognostic model to predict symptoms in patients with TIE MM.

Methods: In this population-based, retrospective cohort study, using multiple administrative health care databases linked using a unique encrypted patient identifier in Ontario, Canada, symptoms were identified using the patient self-reported Edmonton Symptom Assessment System (ESAS) at each clinic visit.

Characterizing sexuality and assessing predictors of sexual satisfaction in patients with multiple myeloma and other hematological cancers.

Purpose: Existing studies documenting cancer-related sexual concerns among hematological cancer patients tend to group all types of hematological cancer together, overlooking potentially unique concerns associated with multiple myeloma (MM). This study is the first to characterize sexuality in MM and to examine predictors of sexual satisfaction for MM, comparatively with participants with other hematological cancer types.

Methods: We conducted a cross-sectional self-report survey-based study.

Prevalence and Significance of Incidental PET/CT Findings of Cancer Detected in Patients Evaluated for Their Primary Hematologic Malignancy: A Systematic Review.

In the evaluation of a patient's primary hematologic malignancy, positron emission tomography/computed tomography (PET/CT) imaging may incidentally detect a concerning abnormality suggestive of a second concurrent cancer. Despite accounting for nearly 10% of all cancers diagnosed in Canada, there has yet to be a systematic review focused on the prevalence and significance of these incidental PET/CT findings in the context of primary hematologic malignancies. As such, a systematic search strategy was employed on MEDLINE and Embase to document the prevalence and clinical significance of incidental PET/CT findings suggestive of a second concurrent cancer detected in patients evaluated for their primary hematologic malignancy.

A Prognostic Survival Model Incorporating Patient-Reported Outcomes for Transplant-Ineligible Patients With Multiple Myeloma.

Developing prognostic tools specifically for patients themselves represents an important step in empowering patients to engage in shared decision-making. Incorporating patient-reported outcomes may improve the accuracy of these prognostic tools. We conducted a retrospective population-based study of transplant-ineligible (TIE) patients with multiple myeloma (MM) diagnosed between January 2007 and December 2018.

Monoclonal Gammopathy of Undetermined Significance in Patients With Transthyretin Amyloidosis (ATTR): Analysis Using the iStopMM Criteria.

Introduction: To identify the prevalence of monoclonal gammopathy of undetermined significance (MGUS) in patients with transthyretin amyloid (ATTR). We used the iStopMM study revised reference ranges for serum free light-chain (sFLC) corrected for eGFR to identify ATTR patients with light-chain MGUS (LC-MGUS). Characteristics and frequencies of the ATTR cohort with underlying MGUS was compared to a cohort of MGUS patients without ATTR.

Real-world Outcomes With Cumulative Bortezomib Dose and Efficacy in the Treatment of Transplant-ineligible Multiple Myeloma With Cyclophosphamide, Bortezomib, and Dexamethasone.

Background: Higher cumulative dose of bortezomib, a key component of Multiple Myeloma (MM) treatment regimens, has been shown to improve outcomes in MM patients, but must be balanced with toxicities including peripheral neuropathy. In this study, we studied the effect of cumulative bortezomib dose on survival, depth of response, and discontinuation rate in transplant ineligible MM patients.

Patients And Methods: Data from 70 patients treated with Cyclophsophamide, Bortezomib, and Dexamethasone (CyBorD) in a single Canadian center were grouped according to above vs below median cumulative bortezomib dose and analyzed for progression-free survival (PFS), overall survival (OS), depth of response, and discontinuation rate.

Amyloidosis and COVID-19: experience from an amyloid program in Canada.

Severe acute respiratory syndrome coronavirus (SARS-CoV2) and associated COVID-19 infection continue to impact patients globally. Patients with underlying health conditions are at heightened risk of adverse outcomes from COVID-19; however, research involving patients with rare health conditions remains scarce. The amyloidoses are a rare grouping of protein deposition diseases.

Real-world treatment patterns for patients with newly diagnosed multiple myeloma in Alberta, Canada.

The purpose of this study is to describe the real-world multiple myeloma (MM) population in Alberta by examining patient/clinical characteristics and the treatment landscape. A retrospective, observational study was conducted using province-wide, administrative health data from Alberta, Canada evaluating newly diagnosed MM (NDMM) patients. Between 1 April 2011 and 31 March 2017, 1377 treated NDMM cases were identified.

Cyclophosphamide, Bortezomib and Methylprednisolone (CyBorMe) for the Treatment of AL Amyloidosis: Initial Experience From a Single Center.

The use of cyclophosphamide, bortezomib and dexamethasone (CyBorD) is widely accepted in the treatment of AL amyloidosis (AL). Recently, the substitution of dexamethasone by methylprednisolone (CyBorMe) appeared to improve response rates and survival outcomes. All consecutive newly diagnosed AL amyloidosis treated with CyBorMe from 01/19 to 08/20 were evaluated.

Impact of COVID-19 on the Diagnosis and Management of Multiple Myeloma: Experience from a Canadian Center.

Background: The impact of coronavirus disease-19 on the management of multiple myeloma (MM) has been recognized. However, the real effect on clinical outcomes remains poorly understood.

Objective: We describe a local experience of the management of MM patients and report their outcomes during the current pandemic.

N-Terminal pro-brain natriuretic peptide (NTproBNP) in patients with symptomatic multiple myeloma: report from a single institution.

Elevated levels of serum cardiovascular markers including natriuretic peptides (NPs) such as amino terminal pro-brain natriuretic peptide (NTproBNP) have been associated with disease severity and survival in cancer patients and more recently in multiple myeloma (MM). In the present study, we retrospectively reviewed 87 consecutive symptomatic TEMM (transplant-eligible) and 126 TIMM (transplant-ineligible) patients treated at our institution that did undergo NTproBNP testing from 2017 to 2020. Median age at diagnosis was 59.

Perceptions of healthcare professionals towards palliative care in internal medicine wards: a cross-sectional survey.

Background: The extension of palliative care services to meet the needs of patients with chronic non-malignant life-limiting conditions faces misconceptions amongst healthcare professionals. A study of prevailing perceptions of healthcare professionals on this wider palliative care service was thus conducted to identify current obstacles, guide the education of local healthcare professionals and improve service accessibility.

Methods: A cross-sectional study was carried out at the Singapore General Hospital.

Treatment response measurements and survival outcomes in a cohort of newly diagnosed AL amyloidosis.

Introduction: The assessment of AL amyloidosis response is based on serum free light chains (sFLC) levels, and serum and urine monoclonal protein investigations. Recently, difference between involved and uninvolved free light chains (dFLC), involved free light chain (iFLC) and complete response (CR) has been reported as independent predictor of survival and a refinement of the hematological response criteria has been proposed by several groups.

Methods: In the current study, all consecutive newly diagnosed symptomatic AL amyloidosis patients were evaluated.

Monoclonal Gammopathy of Undetermined Significance Clinic during the Coronavirus Disease-19 Pandemic: Caring for the Vulnerable in an Academic Medical Center.

Background: Patients with monoclonal gammopathy of undetermined significance (MGUS) have clinical features including older age, presence of medical comorbidities, susceptibility to infections, and thrombotic tendencies which are relevant when assessing their risk during the coronavirus disease (COVID-19) pandemic.

Objective: To study the vulnerability of patients with MGUS during the COVID-19 pandemic, we assessed the local management of MGUS patients and their clinical outcomes.

Methods: Retrospective chart reviews were performed for all patients with MGUS seen at a university medical center clinic (2014-2020).

The impact of COVID-19 in the management of AL amyloidosis and Immunoglobulin Deposition Disease: A single-center experience.

Introduction: Patients with AL amyloidosis and immunoglobulin deposition diseases (IDD) are vulnerable during the COVID-19 pandemic due to the immune compromise from the plasma cell disorder and therapy-related immune defects. We describe a local experience in providing care for patients with AL amyloidosis and IDD.

Method: Patient treatment and disease status since the beginning of the pandemic on March 11, 2020, as declared by WHO, were collected and analyzed.

Age no bar: A CIBMTR analysis of elderly patients undergoing autologous hematopoietic cell transplantation for multiple myeloma.

Background: Upfront autologous hematopoietic stem cell transplantation (AHCT) remains an important therapy in the management of patients with multiple myeloma (MM), a disease of older adults.

Methods: The authors investigated the outcomes of AHCT in patients with MM who were aged ≥70 years. The Center for International Blood and Marrow Transplant Research (CIBMTR) database registered 15,999 patients with MM in the United States within 12 months of diagnosis during 2013 through 2017; a total of 2092 patients were aged ≥70 years.

Cyclophosphamide, Bortezomib and Dexamethasone (CyBorD) for the Treatment of Newly Diagnosed AL Amyloidosis: Impact of Response on Survival Outcomes.

Background: CyBorD (cyclophosphamide, bortezomib, and dexamethasone) is an effective regimen for the treatment of patients with newly diagnosed immunoglobulin light chain (AL) amyloidosis. CyBorD can induce rapid hematologic responses (HRs). However, it remains inadequate to enhance outcomes in high-risk groups.

Liberal Versus Restrictive Red Blood Cell Transfusion Thresholds in Hematopoietic Cell Transplantation: A Randomized, Open Label, Phase III, Noninferiority Trial.

Purpose: Evidence regarding red blood cell (RBC) transfusion practices and their impact on hematopoietic cell transplantation (HCT) outcomes are poorly understood.

Patients And Methods: We performed a noninferiority randomized controlled trial in four different centers that evaluated patients with hematologic malignancies requiring HCT who were randomly assigned to either a restrictive (hemoglobin [Hb] threshold < 70 g/L) or liberal (Hb threshold < 90 g/L) RBC transfusion strategy between day 0 and day 100. The noninferiority margin corresponds to a 12% absolute difference between groups in Functional Assessment of Cancer Therapy-Bone Marrow Transplant (FACT-BMT) score relative to baseline.
