RESUMEN

OBJECTIVES: Treatment options for multicentric Castleman disease (MCD) remain limited. The only FDA-approved drug is siltuximab for idiopathic MCD (iMCD), but the response rate with siltuximab is less than 50%. We performed a systematic review to examine the efficacy and safety of various regimens used for the treatment of MCD. METHODS: A database search on PubMed, Embase, Cochrane, Web of Science, and Clinicaltrials.gov using the terms "Castleman disease," "treatment outcome," and "patient safety" was done. RESULTS AND CONCLUSIONS: Results from a randomized controlled trial and an extension study highlighted the efficacy and long-term safety of siltuximab for iMCD; other trials showed tocilizumab to be a suitable alternative. A recent trial reported high response rates with thalidomide in iMCD patients. Promising results were reported for bortezomib in relapsed/ refractory MCD. For human herpesvirus-8 (HHV8)-associated MCD, rituximab along with doxorubicin therapy followed by maintenance with zidovudine and valganciclovir is the most effective therapy. A single-arm trial has highlighted the potential role of tocilizumab in HHV8-MCD. Data for these regimens are limited and mostly comprise nonrandomized trials. Further research on emerging agents could have a major impact on the treatment of this rare disease.

RESUMEN

Data on the disease course, presenting features, outcomes, and prognosis of younger patients with multiple myeloma (MM) are lacking. Younger patients with MM have historically been considered to have better outcomes primarily based on better tolerance of treatment and lack of medical comorbidities, but the specific age range of this population has not been uniformly defined. Given the lack of consistent data reporting in patients considered to be young MM patients, we performed a scoping review to highlight the research currently available to start drawing conclusions about these patients and highlight unmet areas of need to focus on further investigation. We searched Embase, Cochrane Central Register of Controlled Trials, CINAHL Plus, Web of Science, and the OVID version of MEDLINE including broad terms that embody the concept of young patients with MM. Our final review included 201 studies which were then categorized according to age group, number of patients, outcomes, and comparators to older patients, along with location and database when available. We have chosen to categorize 3 age groupings: <50: young adults with MM (YA MM), 50 to 65: mid-life adults with multiple myeloma (ML MM) and 65+: older adults with multiple myeloma (OA MM). This review demonstrates the heterogeneity that exists in defining and describing young patients with MM, highlights the lack of studies specifically addressing the unique needs of younger patients, and emphasizes areas of future research unique to this population.

RESUMEN

Extra copies of chromosome 1q21 (+1q: gain = 3 copies, amp >= 4 copies) are associated with worse outcomes in multiple myeloma (MM). This systematic review assesses the current reporting trends of +1q, the efficacy of existing regimens on +1q, and its prognostic implications in MM randomized controlled trials (RCTs). Pubmed, Embase and Cochrane Registry of RCTs were searched from January 2012 to December 2022. Only MM RCTs were included. A total of 124 RCTs were included, of which 29 (23%) studies reported on +1q. Among them, 10% defined thresholds for +1q, 14% reported survival data separately for gain and amp, and 79% considered +1q a high-risk cytogenetic abnormality. Amongst RCTs that met the primary endpoint showing improvement in progression free survival (PFS), lenalidomide maintenance (Myeloma XI), selinexor (BOSTON), and isatuximab (IKEMA and ICARIA) were shown to improve PFS for patients with evidence of +1q. Some additional RCT's such as Myeloma XI+ (carfilzomib), ELOQUENT-3 (elotuzumab), and HOVON-65/GMMG-HD4 (bortezomib) met their endpoint showing improvement in PFS and also showed improvement in PFS in the +1q cohort, although the confidence interval crossed 1. All six studies that reported HR for +1q patients vs. without (across both arms) showed worse OS and PFS for +1q. There is considerable heterogeneity in the reporting of +1q. All interventions that have shown to be successful in RCTs and have clearly reported on the +1q subgroup have shown concordant direction of results and benefit of the applied intervention. A more standardized approach to reporting this abnormality is needed.

RESUMEN

INTRODUCTION: Oncology media websites such as Oncology Live (OncLive) and Targeted Oncology (TargetedOnc) play an important role in the dissemination of oncology news to patients and clinicians; however, the quality of the content on these websites has not been assessed. Our study aimed to analyze content from these websites and assess financial conflicts of interest (FCOI) amongst speakers interviewed on these websites. METHODS: Articles published on OncLive and TargetedOnc during October 2021, were prospectively captured and analyzed. The primary outcome of our study was the quality of oncology news reporting in OncLive and TargetedOnc. We assessed the FCOI amongst speakers using data from Open Payments. RESULTS: We examined 196 articles (OncLive 108, TargetedOnc 88). Limitations of cited research were reported in 7% (7/105) of OncLive and zero TargetedOnc articles. Benefit and risks in absolute numbers were reported in 28% (28/99) of OncLive and 16% (7/45) of TargetedOnc articles. Independent experts were quoted in 47% (51/108) and 51% (44/86) of the OncLive and TargetedOnc articles, respectively (Table 3). Pharmaceutical executives were quoted in 18% (20/108) and 11% (10/88) of OncLive and TargetedOnc articles, respectively. No FCOI disclosures were listed or reported for any articles. The mean general payment received from industry by United States physicians was $63,861 in 2019 and $39,639 in 2020. CONCLUSION: Our study demonstrates low quality and potentially biased reporting of oncology news on OncLive and TargetedOnc. Careful safeguards, oversight and reporting of relevant FCOI are needed to maintain the quality and transparency of content being provided.

RESUMEN

Adult T-cell leukemia/lymphoma (ATLL) remains challenging to treat and has dismal outcome. Allogeneic stem-cell transplantation (allo-SCT) has promising results, but data remain scarce. In this single-center retrospective analysis of 100 patients with ATLL from north America (67 acute, 22 lymphomatous), 17 underwent allo-SCT and 5 autologous SCT (ASCT), with a median follow-up of 65 months. Post-transplant 3-years relapse incidence (RI) and non-relapse mortality (NRM) were 51% and 37%, respectively, and 3-year progression-free survival (PFS) and overall survival (OS) were 31% and 35%, respectively. ASCT 1-year RI was 80% compared to 30% in allo-SCT (p = 0.03). After adjusting for immortal-time bias, allo-SCT had significantly improved OS (HR = 0.4, p = 0.01). In exploratory multivariate analysis, patients achieving first complete response and Karnofsky score ≥ 90 had significantly better outcomes, as did Black patients, compared to Hispanics, who had worse outcome. In transplanted patients, 14 died within 2 years, 4 of which ASCT recipients. Our data are the largest ATLL transplant cohort presented to date outside of Japan and Europe. We show that allo-SCT, but not ASCT, is a valid option in select ATLL patients, and can induce long term survival, with 40% of patients alive after more than 5 years.

RESUMEN

VEXAS (vacuoles, E1 enzyme, X linked, autoinflammatory, somatic) syndrome is a novel inflammatory syndrome that was first described in December 2020. Patients with VEXAS syndrome have a somatic mutation in the UBA1 gene, inflammatory conditions and usually haematological conditions. Haematological conditions reported in patients with VEXAS syndrome include myelodysplastic syndrome (MDS), clonal cytopenia of undetermined significance, plasma cell neoplasm including multiple myeloma/monoclonal gammopathy of undetermined significance, haemophagocytic lymphohistiocytosis and monoclonal B-cell lymphocytosis. Here we describe a patient with VEXAS syndrome who had a progression of MDS to MDS/myeloproliferative neoplasm overlap syndrome. The ocular findings so far reported in these patients include episcleritis, uveitis, blepharitis and orbital cellulitis. Here we report retinal detachment as a clinical feature of VEXAS syndrome. This finding has a significant implication in patient management as it warrants higher vigilance for this sight-threatening complication.

RESUMEN

With recent advances in novel chemotherapeutic agents and increasing use of autologous hematopoietic stem cell transplant, there has been a significant improvement in outcomes for patients with AL Amyloidosis. Daratumumab, with its excellent safety and efficacy profile, appears to be an ideal treatment option for patients with newly diagnosed as well as relapsed refractory AL amyloidosis. In this systematic review, we analyzed the published literature on the role of Daratumumab in pretreated relapsed and refractory AL-amyloidosis patients using PubMed, Embase, Cochrane, and clinicaltrials.gov databases. A total of 16 studies evaluated the role of Daratumumab as monotherapy (DMT) or in combination with other chemotherapeutic agents (DCT). DMT and DCT were associated with promising efficacy with hematologic and organ responses (cardiac/renal) seen in 50%-90% and 50%-80% of the patients, respectively. Daratumumab appeared to be well tolerated with no significant treatment-related adverse events as DMT or DCT.

RESUMEN

There is increasing evidence regarding the role of various maintenance therapy (MT) strategies after initial induction to treat newly diagnosed transplant-ineligible patients with MM. We reviewed the literature on available regimens for patients with transplant-ineligible newly diagnosed multiple myeloma (NDMM). Lenalidomide (R)-based regimens are still the front-line therapy, but there is an increasing use of bortezomib-based regimens. The MT regimen is mainly based on the initial induction regimen. MT has shown survival benefits compared with patients without maintenance therapy. The most common adverse effects of MT include anemia, neutropenia, thrombocytopenia, infections, and peripheral neuropathy. In conclusion, induction followed by maintenance based on lenalidomide, bortezomib, ixazomib, or daratumumab-based regimens has shown promising results. Therefore, it is essential to conduct more clinical trials to better understand the role of MT in the treatment of NDMM patients who are not candidates for autologous stem cell transplantation.

RESUMEN

Background: Natural killer (NK) cells play a vital role in early immune reconstitution following allogeneic hematopoietic stem cell transplantation (HSCT). Methods: A literature search was performed on PubMed, Cochrane, and Clinical trials.gov through April 20, 2022. We included 21 studies reporting data on the impact of NK cells on outcomes after HSCT. Data was extracted following the PRISMA guidelines. Pooled analysis was done using the meta-package (Schwarzer et al.). Proportions with 95% confidence intervals (CI) were computed. Results: We included 1785 patients from 21 studies investigating the impact of NK cell reconstitution post-HSCT (8 studies/1455 patients), stem cell graft NK cell content (4 studies/185 patients), therapeutic NK cell infusions post-HSCT (5 studies/74 patients), and pre-emptive/prophylactic NK cell infusions post-HSCT (4 studies/77 patients). Higher NK cell reconstitution was associated with a better 2-year overall survival (OS) (high: 77%, 95%CI 0.73-0.82 vs low: 55%, 95%CI 0.37-0.72; n=899), however, pooled analysis for relapse rate (RR) or graft versus host disease (GVHD) could not be performed due to insufficient data. Higher graft NK cell content demonstrated a trend towards a better pooled OS (high: 65.2%, 95%CI 0.47-0.81 vs low: 46.5%, 95%CI 0.24-0.70; n=157), lower RR (high: 16.9%, 95%CI 0.10-0.25 vs low: 33%, 95%CI 0.04-0.72; n=157), and lower acute GVHD incidence (high: 27.6%, 95%CI 0.20-0.36 vs low: 49.7%, 95%CI 0.26-0.74; n=157). Therapeutic NK or cytokine-induced killer (CIK) cell infusions for hematologic relapse post-HSCT reported an overall response rate (ORR) and complete response (CR) of 48.9% and 11% with CIK cell infusions and 82.8% and 44.8% with NK cell infusions, respectively. RR, acute GVHD, and chronic GVHD were observed in 55.6% and 51.7%, 34.5% and 20%, and 20.7% and 11.1% of patients with CIK and NK cell infusions, respectively. Pre-emptive donor-derived NK cell infusions to prevent relapse post-HSCT had promising outcomes with 1-year OS of 69%, CR rate of 42%, ORR of 77%, RR of 28%, and acute and chronic GVHD rates of 24.9% and 3.7%, respectively. Conclusion: NK cells have a favorable impact on outcomes after HSCT. The optimal use of NK cell infusions post-HSCT may be in a pre-emptive fashion to prevent disease relapse.

RESUMEN

A 47-year-old female with a past medical history of morbid obesity and hypertension presented with acute onset dizziness that started while she was at work one evening. She did not have chest pain or dyspnea. She had vital signs within an acceptable range, oxygen saturation of 98%-99%, and was not in acute distress. Examination including the Dix-Hallpike maneuver was unremarkable. Computed tomography angiography (CTA) of the head and neck disclosed bilateral pulmonary embolism without any evidence of cerebral ischemia. CTA chest confirmed the diagnosis of bilateral pulmonary emboli. Importantly, besides the obesity, the patient did not have any other risk factors of pulmonary embolism including recent immobilization, surgery, hormonal therapy or contraceptive use, and personal or family history of thromboembolic disorders. However, she was diagnosed with COVID-19 infection six months back with symptoms not requiring hospitalization. Following further workup for her dizziness and neurology evaluation, in the absence of any other plausible etiology, her presenting symptom was attributed to the atypical presentation of pulmonary embolism. She was treated with heparin in the hospital and discharged on apixaban. Her symptoms had resolved at the time of discharge.

RESUMEN

Pneumocystis pneumonia (PCP) is an opportunistic infection caused by Pneumocystis jirovecii. PCP due to immunosuppressive drugs is rarely reported in the literature. Herein we present a case of PCP in a 49-year-old patient who presented with progressive shortness of breath, dry cough, and low-grade fever. History revealed that he was taking prednisolone daily for his hyperactive airway disease. His temperature was 99oF, and he had bilateral crackles in the lungs with resonant wheezing. High-resolution computed tomography showed diffuse ground-glass haze and cystic lesions in the middle and upper zones of both lungs. He was commenced on intravenous ceftriaxone and methylprednisolone based on provisional diagnosis of interstitial pneumonia. However, his condition worsened. His human immunodeficiency virus (HIV) test was reactive, and his CD4+ count was 275 cells/mm3. Bronchoalveolar lavage revealed PCP by direct immunofluorescent assay. Additional serum testing revealed marked elevation of beta-D-glucan, consistent with PCP diagnosis due to glucocorticoid use. Trimethoprim-sulfamethoxazole and voriconazole were initiated, and his respiratory symptoms started improving. His respiratory condition improved on day 9, and he was discharged with follow-up.

RESUMEN

Treatment options are limited for multiple myeloma patients who have developed four/five drug-refractory disease. Selinexor (Sel) and belantamab mafodotin (belamaf) were recently approved by the US FDA for treatment of RRMM. The toxicity profile of these drugs is a concern since these agents are used in patients who have already undergone multiple lines of treatment. In this review, we discuss the toxicity profile and strategies for the management of toxicities of Sel and belamaf for the treatment of RRMM. We conducted a comprehensive literature search on PubMed, Embase, Cochrane, and Clinicaltrials.gov using the terms "selinexor", "belantamab", "belamaf", and "multiple myeloma" without applying any limitations based on the date of the study, language, or country of origin. The most common hematological toxicity associated with these two drugs is thrombocytopenia. Cytopenias, constitutional symptoms, gastrointestinal effects, and hyponatremia are the major toxicities of Sel. Keratopathy and anemia are the major toxicities of belamaf. Treatment modifications and dose interruption are usually needed when side effects are more than grade II. As these are newer drugs with limited data, continuous surveillance and monitoring are warranted during the treatment course with early mitigation strategies.

RESUMEN

Treatment options for newly diagnosed aplastic anemia (AA) patient includes upfront allogeneic hematopoietic stem cell transplant (HSCT) or immunosuppressive therapy (IST). With recent advances in supportive care, conditioning regimens and post-transplant immunosuppression the overall survival for HSCT approaches 70-90%. Transplant eligibility needs to be assessed considering age, comorbidities, donor availability and probability of response to immunosuppressive therapy (IST). Upfront HSCT should be offered to children and young adults with matched related donor (MRD). Upfront HSCT may also be offered to children and young adults with rapidly available matched unrelated donor (MUD) who require urgent HSCT. Bone marrow (BM) graft source and cyclosporine (CsA) plus methotrexate (MTX) as graft versus host disease (GVHD) prophylaxis are preferable when using anti-thymocyte globulin (ATG) based conditioning regimens. Alemtuzumab is an acceptable alternative to ATG and is used with CsA alone and with either BM or peripheral blood stem cells (PBSC). Cyclophosphamide (CY) plus ATG conditioning is preferable for patients receiving MRD transplant, while Fludarabine (Flu) based conditioning is reserved for older adults, those with risk factors of graft failure and those receiving MUD HSCT. For haploidentical transplant, use of low dose radiotherapy and post-transplant cyclophosphamide has resulted in a marked reduction in graft failure and GVHD.

RESUMEN

An intense itching localized to dermatomes is a rare symptom of multiple sclerosis (MS). Herein, we report a case of a 45-year-old female who presented with severe itching and tingling sensation, gait disturbance, and bilateral paresthesia for one week. She also had a history of multiple admission in the hospital due to recurrent walking abnormalities and numbness and tingling of both hands associated with intermittent psychiatric symptoms. The neurological examination revealed spastic quadriparesis with lower limb muscles affected more than the upper limbs, numbness, and sensory loss in the upper extremities in the glove and stocking pattern. Magnetic resonance imaging (MRI) revealed multiple small rounded periventricular plaques in both hemispheres and along the long axis of the corpus callosum (fluid-attenuated inversion recovery/FLAIR sequence), and cerebrospinal fluid analysis revealed the presence of oligoclonal bands, suggestive of MS. She was commenced on methylprednisolone and carbamazepine, leading to progressive resolution of her signs and symptoms. She was discharged with monthly natalizumab, and she was doing well on her follow-up.

RESUMEN

A 10-year-old boy with no past medical history presented with complaints of nausea and vomiting associated with morning headache for the last month. Ophthalmic nerve and eye exam showed diplopia and strabismus with no other significant findings on physical and neurological examination. Magnetic resonance imaging (MRI) of the brain revealed a homogenous hyperdense and enhancing mass in the pineal region. The endoscopic biopsy of the pineal region demonstrated the cells with highly pleomorphic and hyperchromatic nuclei with an increase in mitotic activity. There were many vessels but no area of vascular proliferation and necrosis. Granular bodies with eosinophilia were identified. Immunohistochemistry was positive for class III b-tubulin with epidermal growth factor receptor (EGFR) staining and glial fibrillary acidic protein (GFAP). Immunostaining was positive for p53, Phosphatase and Tensin homolog (PTEN), and oligodendrocyte transcription factor (OLIG2), while staining for cluster of differentiation (CD)34, cytokeratin (CK), human melanoma black (HMB)45, and isocitrate dehydrogenase (IDH)-R132H mutation was negative, consistent with atypical pleomorphic neoplasm of the pineal region. The patient underwent tumor resection via a sub-occipital trans-tentorial approach, followed by one dose of chemotherapy. The patient experienced a resolution of the symptom and was doing well on his bi-monthly follow up.

RESUMEN

Coronavirus disease-2019 (COVID-19), first reported in China during December of 2019, is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Infection later spread very rapidly around the globe with over 8,708,008 cases reported, including more than 461,715 deaths reported across at least 216 countries by June 20, 2020. It was declared as a global pandemic by the World Health Organization (WHO) on March 11, 2020. With the rapidly increasing number of positive cases and deaths, there is a dire need for effective treatment. An urgent unmet need led to the planning and opening of multiple drug development trials for treatment and vaccine development. In this article, we have compiled comprehensive data on many candidate drugs such as remdesivir, favipiravir, ribavirin, umifenovir, arbidol, lopinavir, ritonavir, baricitinib, hydroxychloroquine, nitazoxanide, azithromycin, baloxavir, oseltamivir, losartan, and tocilizumab. We have tabulated available data on various clinical trials testing various aspects of COVID-19 therapeutics.

RESUMEN

Pancreatic cancer is one of the most aggressive malignancies of the digestive tract and carries a poor prognosis. The majority of patients have advanced disease at the time of diagnosis. Surgical resection offers the only curative treatment, but only a small proportion of patients can undergo surgical resection. Radiofrequency ablation (RFA) is a well-known modality in the management of solid organ tumors, however, its utility in the management of pancreatic cancer is under investigation. Since the past decade, there is increasing use of RFA as it provides a feasible palliation treatment in the management of unresectable pancreatic cancer. RFA causes tumor cytoreduction through multiple mechanisms such as coagulative necrosis, protein denaturation, and activation of anticancer immunity. The safety profile of RFA is controversial because of the high risk for complications, however, small prospective and retrospective studies have shown promising results in its applicability for palliative management of unresectable pancreatic malignancies. In this review, we discuss different approaches of RFA, their indications, technical accessibility, safety, and major complications in the management of unresectable pancreatic cancer.
