A plain language summary of the PERSEUS study of daratumumab plus bortezomib, lenalidomide, and dexamethasone for treating newly diagnosed multiple myeloma.

What is this summary about? This summary describes the first analysis of the PERSEUS study, which looked at adults with multiple myeloma that had never been treated before, also called newly diagnosed multiple myeloma. Multiple myeloma is a type of cancer in the blood, specifically in plasma cells within the soft, spongy tissue in the center of most bones, called the bone marrow. Researchers wanted to see if adding daratumumab (D) to a standard treatment of three other medicines called VRd, which stands for bortezomib (V), lenalidomide (R), and dexamethasone (d), could stop the multiple myeloma from getting worse and help participants live longer without multiple myeloma.Half of the participants were assigned to the treatment plan with daratumumab; they received D-VRd during initial treatment phases (induction and consolidation), followed by daratumumab as well as lenalidomide (D-R) in the maintenance phase. The other half of participants received treatment without daratumumab; they received VRd induction and consolidation followed by lenalidomide alone (R) maintenance. In addition, all participants were able to receive an autologous stem cell transplant, a procedure used to further help reduce multiple myeloma.What were the results? At the time of this analysis of PERSEUS, about 4 years after participants started the study, participants who received D-VRd treatment followed by D-R maintenance had a better response to treatment (as measured by specific markers of multiple myeloma) and were more likely to be alive and free from their multiple myeloma getting worse in comparison to participants who received VRd followed by R maintenance. Side effects (unwanted or undesirable effects of treatment) in both treatment groups were in line with the known side effects of daratumumab and VRd.What do the results mean? The results of the PERSEUS study showed that including daratumumab in D-VRd induction/consolidation and D-R maintenance was better for treating multiple myeloma than the current standard VRd treatment followed by R maintenance alone in adults with a new diagnosis of multiple myeloma who were also able to receive an autologous stem cell transplant. Of importance, there were no unexpected side effects in either group.Clinical Trial Registration: NCT02874742 (GRIFFIN) (ClinicalTrials.gov).

Virtual Reality Distraction: A Novel Behaviour Management Technique.

Virtual reality distraction (VRD) is developing technologies for behavior management that can assist a child in adjusting to the dental setting and provide high-quality dental care. The purpose of this literature is to shed light on VRD and its application to the treatment of pediatric dental patients.

Patient characteristics associated with dose modifications for VRd among newly diagnosed multiple myeloma patients.

Aim: To evaluate among multiple myeloma (MM) patients, the proportions with first-line bortezomib/lenalidomide/dexamethasone (VRd) dose modifications and the associated baseline patient characteristics. Patients & methods: Adult MM patients treated with first-line VRd were selected from the Optum claims database. VRd dose modifications were defined based on lenalidomide dose. Results: Among 1497 MM patients, 33% received VRd lite and 22% VRd reduced. Compared with VRd regular, VRd lite usage was more likely to be associated with patients aged ≥75 years and female sex; VRd reduced usage was more likely to be associated with female sex and frailty. Conclusion: A large proportion of MM patients received VRd dose modifications in the real-world, which could potentially result in reduced effectiveness of VRd.

Multiple Myeloma Uncovered Under Excessive Antacid and Chronic NSAID Use in a Young Female.

Multiple myeloma (MM) is a plasma cell dyscrasia in which nearly all cases are diagnosed in patients over 40 years old. This report illustrates a case of a young female who presented with severe generalized weakness, acute kidney injury, hypercalcemia, and anemia. Her symptoms were initially attributed to chronic NSAID and antacid intake, especially given her young age. However, further workup was pursued to rule out other potential diagnoses despite her age. She was ultimately diagnosed with multiple myeloma and started on bortezomib, cyclophosphamide, and dexamethasone. This report emphasizes the importance of maintaining a broad differential diagnosis. Untrained physicians can easily overlook rare cases. Timely diagnosis and treatment are key, and therefore, a high degree of suspicion is crucial for this patient population.

Stent implantation in a patient with non-hemorrhagic vertebral artery dissection associated with severe, continuously progressive stenosis in the posterior inferior cerebellar artery bifurcation region: A case report.

Generally, the prognosis of non-hemorrhagic vertebral artery dissection is good. Treatment should be considered when stenosis progresses or when an aneurysm is formed. However, no clear treatment policy has been established. The purpose of this case report was to describe the treatment policy for non-hemorrhagic onset vertebral artery dissection with severe stenosis around the posterior inferior cerebellar artery (PICA) bifurcation and aneurysm, where stent placement in the vertebral artery was difficult. This report describes healing without complications with stent implantation in the PICA performed to treat non-hemorrhagic vertebral artery dissection with associated severe, continuously progressive stenosis in the PICA bifurcation region. A 36-year-old woman was examined at the authors' hospital for persistent pain in the left posterior neck. Left vertebral arteriography revealed stenosis due to dissection around the PICA bifurcation and aneurysm formation at the distal position. Due to the progression of stenosis, there were concerns about PICA occlusion, and stent implantation in the vertebral artery was performed via the PICA. Neck pain ceased immediately after surgery, and 3 months later, cerebral angiography showed favorable patency of the PICA and decreased aneurysm size. This case suggests that stent implantation in the PICA might be a useful treatment option for non-hemorrhagic vertebral artery dissection with associated severe stenosis in the PICA bifurcation region.

Impact of Induction With VCD Versus VRD on the Outcome of Patients With Multiple Myeloma After an Autologous Hematopoietic Stem Cell Transplantation.

Induction therapy with a triplet regimen, followed by high-dose therapy and autologous hematopoietic stem cell transplantation (auto-HCT), is the standard of care for newly diagnosed, transplant-eligible patients with multiple myeloma (MM). Bortezomib-dexamethasone with cyclophosphamide (VCD) or lenalidomide (VRD) are the most used induction regimens. However, previous studies comparing VCD and VRD showed disparate results. The goal of this retrospective study was to compare the "real-world" results of VCD and VRD in transplant-eligible MM patients outside of a clinical trial. We identified 322 patients who received VRD or VCD induction before auto-HCT at our institution. All patients received melphalan conditioning and single-agent lenalidomide maintenance therapy. Overall, 114 patients received VCD, and 208 received VRD. The median age at auto-HCT was 61.9 years (range 33.9-79.6), with 35.4% (114/322) of the cohort being 65 years of age or older. The overall response rate was 99.7% after auto-HCT, with a significantly lower complete remission rate as the final response in the VCD compared to the VRD group (34% versus 53%; P = .001). However, there was no significant difference between the best response rate of very good partial response (VGPR) or better in the VCD compared to the VRD group (92% versus 85%; P = .078). The median duration of ≥VGPR was 50.0 months (95% confidence interval [CI], 42.0-69.1) for both cohorts, and there was no difference between VCD and VRD (P = .769; hazard ratio, 0.95; 95% CI, 0.69-1.31). Median follow-up of survivors was 73 months. There was no difference in the relapse rate between VCD and VRD (P = .749). Median progression-free survival (PFS) was 48.7 months in the VCD and 44.6 months in the VRD group (P = .858). Median overall survival (OS) was 103.8 months with VCD and 101.7 months with VRD (P = .891). At 5 years, the PFS and OS were 38.1% and 76.9% for the VCD group, respectively, and 40.7% and 74.6% for the VRD group, respectively. On multivariate analysis for OS in the entire cohort, Revised International Staging System I and post-auto-HCT best response of stringent complete response (sCR)/CR emerged as significant predictors of superior OS. There was no impact of the type of induction regimen on the OS in the multivariate analysis. Induction therapy with VCD compared to VRD was associated with a lower CR rate, but there was no difference in PFS or OS between the 2 regimens.

Real-world long-term outcomes in multiple myeloma with VRD induction, Mel200-conditioned auto-HCT, and lenalidomide maintenance.

Standard-of-care for newly-diagnosed, autologous hematopoietic stem cell transplantation (auto-HCT)-eligible, multiple myeloma (MM) patients includes bortezomib, lenalidomide, and dexamethasone (VRD) induction followed by melphalan 200 mg/m2 (Mel200)-conditioned auto-HCT and lenalidomide maintenance. We completed a retrospective case series assessing outcomes of 187 MM patients who received this regimen at our institution. The 100-day non-relapse mortality incidence was zero. Before auto-HCT, 9.6 and 52.9% of patients achieved a complete response (CR) or ≥ very good partial response (VGPR), respectively. At day-100 post-transplant, 29.4 and 74.9% had achieved a CR/stringent-CR (sCR) or ≥ VGPR, respectively. At the last evaluation, 57.2% of patients had CR/sCR and 87.1% had ≥ VGPR. Median follow-up, progression-free survival (PFS), and overall survival (OS) were 63.2, 50, and 101.7 months, respectively. The 5-year PFS and OS were 43.1 and 79%. High-risk cytogenetics was associated with worse outcomes. This study illustrates that VRD induction, Mel200-conditioned auto-HCT, and lenalidomide maintenance are associated with good outcomes in MM.

[Cooccurrence of classic Hodgkin lymphoma and multiple myeloma].

Although classic Hodgkin's lymphoma (CHL) sometimes develops after treatment for multiple myeloma (MM), simultaneous diagnosis of both malignancies is extremely rare without previous treatment history. Here we describe a case of a 54-year-old female who complained of left cervical lymphadenopathy. Biopsy specimen from the left cervical lymph node revealed mixed-cellularity CHL. Bone marrow aspirate comprised 10.3% plasma cells. She was diagnosed with MM due to involved: uninvolved serum free light chain ratio of >100. She achieved complete response for CHL after 4 cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine chemotherapy along with 30 Gy of involved-field radiotherapy. Three years later, bortezomib, lenalidomide, and dexamethasone (VRd-lite) therapy was initiated for MM. Severe neutropenia during her 1st cycle prompted a dosage reduction of lenalidomide and bortezomib. Partial response was achieved after 4 cycles of VRd-lite followed by high-dose melphalan/autologous stem cell transplantation. No severe adverse events were recorded. This was followed by 4 cycles of carfilzomib, lenalidomide, and dexamethasone therapy, which resulted in complete remission. As the number of elderly people increases, multiple myeloma patients with previous history of other malignancies would increase. Our case has shown that VRd-lite therapy may be suitable for those patients.

The efficacy and safety of modified bortezomib-lenalidomide-dexamethasone in transplant-eligible patients with newly diagnosed multiple myeloma.

OBJECTIVES: Bortezomib with lenalidomide and dexamethasone (VRd) is a standard induction regimen for transplant-eligible patients with newly diagnosed multiple myeloma (NDMM). However, some patients discontinue VRd because of severe adverse events, despite its high efficacy. We aimed to study the efficacy of modified dose of VRd (VRd lite) in transplant-eligible patients with NDMM. METHODS: Forty-eight transplant-eligible patients with NDMM were included. VRd lite was administered every 4 weeks. Bortezomib 1.3 mg/m2 was administered subcutaneously on days 1, 8, 15 and 22, and dexamethasone 20 mg was administered orally on the day of and the day after bortezomib administration. Lenalidomide was omitted on days 1, 8 and 15, which are the days of bortezomib administration. RESULTS: The overall response rate (ORR) after four cycles of VRd lite was 83%, including a complete response of 25%. Thirty-eight among the 45 patients who completed at least four cycles of VRd lite received autologous stem cell transplantation (ASCT). The ORR and very good partial response or better were upgraded to 100% and 74%, respectively, following ASCT. CONCLUSION: Our strategy consisting of VRd lite followed by ASCT is, thus, a highly effective and well-tolerated regimen resulting in durable responses in patients with NDMM.

Neuroform Atlas stent deployment through the Barrel vascular reconstruction device for the treatment of a wide-necked acutely ruptured basilar aneurysm.

BACKGROUND: The Barrel vascular reconstruction device is an electrolytically detachable laser-cut closed-cell stent used for neck reconstruction in wide-necked bifurcation aneurysms to support coiling without necessitating dual stent implantation. The purpose is to lower the metal-to-artery ratio and its inherent risk of thromboembolic complications of multiple stents. CASE DESCRIPTION: A 53-year-old woman presenting with subarachnoid hemorrhage due to acutely ruptured basilar tip aneurysm underwent emergency endovascular embolization with the Barrel vascular reconstruction device. Since the stent did not cover the entire neck of the aneurysm, an Atlas stent was released in a Y configuration through the Barrel. The Neuroform Atlas correctly opened through the Barrel and allowed the complete exclusion of the aneurysm. CONCLUSION: If necessary, releasing a Neuroform Atlas through a Barrel vascular reconstruction device is a feasible technique.

The promising future of ventricular restraint therapy for the management of end-stage heart failure.

Complicated pathophysiological syndrome associated with irregular functioning of the heart leading to insufficient blood supply to the organs is linked to congestive heart failure (CHF) which is the leading cause of death in developed countries. Numerous factors can add to heart failure (HF) pathogenesis, including myocardial infarction (MI), genetic factors, coronary artery disease (CAD), ischemia or hypertension. Presently, most of the therapies against CHF cause modest symptom relief but incapable of giving significant recovery for long-term survival outcomes. Unfortunately, there is no effective treatment of HF except cardiac transplantation but genetic variations, tissue mismatch, differences in certain immune response and socioeconomic crisis are some major concern with cardiac transplantation, suggested an alternate bridge to transplant (BTT) or destination therapies (DT). Ventricular restraint therapy (VRT) is a promising, non-transplant surgical treatment wherein the overall goal is to wrap the dilated heart with prosthetic material to mechanically restrain the heart at end-diastole, stop extra remodeling, and thereby ultimately improve patient symptoms, ventricular function and survival. Ventricular restraint devices (VRDs) are developed to treat end-stage HF and BTT, including the CorCap cardiac support device (CSD) (CSD; Acorn Cardiovascular Inc, St Paul, Minn), Paracor HeartNet (Paracor Medical, Sunnyvale, Calif), QVR (Polyzen Inc, Apex, NC) and ASD (ASD, X. Zhou). An overview of 4 restraint devices, with their precise advantages and disadvantages, will be presented. The accessible peer-reviewed literature summarized with an important considerations on the mechanism of restraint therapy and how this acquaintance can be accustomed to optimize and improve its effectiveness.

Contribution of the straightening effect of the parent artery to decreased recanalization in stent-assisted coiling of large aneurysms.

OBJECTIVE The durability of embolization of large aneurysms is enhanced by use of the neck-bridging stent. However, it remains unclear what factors contribute to decreased recanalization. The purpose of this study was to demonstrate the contribution of the straightening effect of the parent artery to the durability of stent-assisted coiling for large aneurysms. METHODS Of the 182 aneurysms treated by embolization since the introduction of the neurovascular stent, 82 consecutive unruptured aneurysms with a diameter greater than 7 mm were selected. There were 52 aneurysms treated with a stent (Group S) and 30 treated without a stent (Group NS). Occlusion status was evaluated 12 months after embolization with digital subtraction angiography. The vascular angle of the parent artery was measured before, immediately after, and 12 months after embolization. The rates of recanalization were compared between Group S and Group NS. In Group S, the rates of recanalization were further compared between those aneurysms with and without a significant angle change. RESULTS The rate of major recanalization was 9.6% in Group S and 26.7% in Group NS. The volume embolization ratio was 32.6% in Group S and 31.6% in Group NS, with no statistically significant difference. However, the angulation change before and after coiling was significantly higher in Group S (10.6°) than in Group NS (0.9°). The difference in the angulation was more evident 12 months after coiling (19.1° in Group S and 1.5° in Group NS). In Group S, recanalization was found in 14.3% of 35 stented aneurysms without a significant angular change when a significant angular change was defined as more than 20°. In contrast, all 17 aneurysms with ≥ 20° of angular change remained occluded. CONCLUSIONS Significant angular change of ≥ 20° most likely leads to decreased recanalization following stent-assisted embolization of large aneurysms.

A phase II trial of small-dose bortezomib, lenalidomide and dexamethasone (sVRD) as consolidation/maintenance therapy in patients with multiple myeloma.

PURPOSE: Consolidation/maintenance therapy induces deep remission in patients with multiple myeloma (MM); however, the most suitable regimen has been under investigation. The combination therapy with bortezomib, lenalidomide and dexamethasone (VRD) is a powerful regimen for relapsed/refractory as well as newly diagnosed MM as an induction therapy. However, severe adverse events (AEs) may become a problem when VRD is introduced without dose reduction as a consolidation/maintenance therapy. METHODS: In this single-arm phase II study, we evaluated the efficacy of small-dose VRD regimen (sVRD) in the consolidation/maintenance setting. Sixteen patients who had partial response (PR) or better after any induction therapy were enrolled. Patients received at least six 28-day cycles of subcutaneous bortezomib (1.3 mg/m2 on days 1 and 15), lenalidomide (10 mg on days 1-21) and dexamethasone (40 mg on days 1, 8, 15 and 22). RESULTS: The overall response rate and the complete response (CR) rate were 100 and 43.8 %, respectively. In particular, one patient with CR and two patients with very good PR at enrollment achieved stringent CR during 6 courses of sVRD. With a median follow-up time of 29.4 months, the median progression-free survival (PFS) and overall survival (OS) were not reached, while the PFS and OS rates at 2.5 years were 66.6 and 77.3 %, respectively. Univariate analysis demonstrated that disease progression as a reason for discontinuation of sVRD had a negative impact on OS. There were no grade 3 or 4 hematologic or nonhematologic AEs. CONCLUSION: Our sVRD regimen as a consolidation/maintenance therapy was highly effective and well tolerable.

Von recklinghausen disease: one patient - various problems.

von Recklinghausen disease (vRD), more widely known as neurofibromatosis type 1, belongs to a group of genetic disorders and it is considered to be the most common genodermatosis. The disease has an autosomal dominant pattern of inheritance that involves mutations within the NF1 gene located on chromosome 17 in locus q11.2. The product of the NF1 gene is neurofibromin and the protein is well known to be a tumor suppressor factor. This counteracts possible overactivity of RAS (protein)/MAPK (mitogen-activated protein kinase) and RAS/PI3K/AKT/mTOR (phoshatydyloinositol-3-kinase/V-akt murine thy-moma viral oncogene homologue/mammalian target of rapamycin) signaling transduction pathways, preventing from uncontrolled cell proliferation and subsequent tumor formation. A loss of proper functioning of this protein leads to a development of vRD; however, a large variability in a phenotype of the disease and the onset of cutaneous findings, not necessarily in childhood, may provide a clinical diagnosis of the disease late in adulthood. We present a 52-year-old male in whom the diagnosis of vRD was proposed in the sixth decade of life, despite of multiple nodular lesions disseminated over the skin of the whole body and different neurological disturbances, not considered for a long time as manifestations of genodermatosis.

New diagnosis of multiple myeloma in a patient with mantle cell lymphoma: Shared genetic factors or simple coincidence?

Multiple Myeloma and Mantle Cell Lymphoma are well defined hematological malignancies. Understanding of their pathogeneses has led to new therapies and increased survival. We report on a 64-yr-old female who was diagnosed with mantle cell lymphoma in 2003, then multiple myeloma in 2010. We identified only few other cases of concomitant MM and MCL. We also explored the importance of t(11;14)(q13;q32). The development of these two disorders in the same patient may simply be due to chance; however, it may also represent a common genetic hit affecting the B-cell population leading to development of two different malignancies.
