RESUMO
Selinexor (Seli) is a first-in-class, oral selective inhibitor of the nuclear export protein, exportin-1 (XPO1). Seli exhibits its antitumor effect through the blockage of XPO1, which increases nuclear retention of tumor suppressor proteins (TSPs), including p53, thereby limiting the translation of oncogenes, triggering cell cycle arrest and the death of malignant cells. Multiple Myeloma (MM) patients with del17p are deficient in TP53 and have a particularly poor prognosis. Given its unique mechanism of action, we investigated whether Seli has increased efficacy in RRMM patients with del17p compared to other high-risk cytogenetics (OHRC). This is an IRB-approved observational study of RRMM patients with high-risk cytogenetics (del17p, t (4;14), t (14;16) or gain 1q) or standard-risk cytogenetics treated at the Levine Cancer Institute (LCI) with a Seli-based regimen between January 2019 and December 2022. Time-to-event endpoints (PFS, OS) were evaluated using Kaplan-Meier (KM) methods. Log-rank tests compared time-to-event endpoints between cohorts [del17p vs. OHRC vs. standard risk]. We identified 40 RRMM patients with high-risk cytogenetics, including 16 patients with del17p and 24 patients with OHRC, as well as 20 with standard-risk cytogenetics. The median age was 62.5 vs. 69 vs. 65.5 years (del17p group vs. OHRC vs. standard risk). The median prior line of therapies was five (range: 3-16) with similar rates of prior autologous stem cell transplant in all arms (68.8% vs. 62.5% vs. 70.0%). The most frequently used regimens were Seli-Pomalidomide-dexamethasone(dex) or Seli-Carfilzomib-dex (Seli-Kd) in the del17p group and Seli-Kd in the OHRC and standard-risk groups. The median time to start the Seli-based regimen after initial MM diagnosis was 5.6 years for the del17p group, 4.1 years in OHRC, and 4.8 years in the standard-risk group. The median follow-up time after the start of the Seli-based regimen was 10.5 months (mos) in the del17p group, 8.4 mos in OHRC, and 10.3 mos in the standard-risk group. In the del17p group, 50% had an objective response, 41.7% in the OHRC, and 35% in the standard-risk group (p = 0.71). Depth of response was also similar across the arms (12.5% vs. 12.5% vs. 10.0% VGPR p = 0.99). The median OS was 10.9 mos in the del17p group, 10.3 mos in the OHRC, and 10.3 mos in the standard-risk group (p = 0.92). The median OS was 15.5 mos for patients who received Seli as a bridging therapy versus 9 mos for Seli use for other reasons rather than as a bridge. Overall, Seli-based regimens showed promising responses even in this heavily pretreated population. Our analysis suggests that Seli-based regimens lead to similar outcomes among RRMM patients with del17p, OHRC, and standard-risk cytogenetics. This contrasts with previously reported outcomes using combinations of novel therapies in this population, where the del17p patients often have a poorer prognosis. Interestingly, our data suggest that Seli is a particularly effective bridging modality for patients preparing for CAR-T cell therapies in our population. Further investigation into this population is warranted, including in earlier lines of therapy, in hopes of seeing a more durable response.
RESUMO
Adoptive cellular immunotherapy, mainly hematopoietic stem cell transplant and CAR-T cell therapy have revolutionized treatment of patients with acute leukemia. Indications and inclusion criteria for these treatments have expanded in recent years. While these therapies are associated with significant improvements in disease response and overall survival, patients may experience adverse events from associated chemotherapy conditioning, engraftment, cytokine storm, supportive medications, and post-transplant maintenance targeted therapies. Supportive oncodermatology is a growing specialty to manage cutaneous toxicities resulting from the anti-cancer therapies. In this review, we summarize diagnosis and management of the common cutaneous adverse events including drug eruptions, graft-versus-host disease, neoplastic and paraneoplastic complications in patients undergoing cellular therapies.

INTRODUCTION: COVID-19 has profound effects on patients with multiple myeloma (MM) mainly due to underlying immune dysfunction and associated therapies leading to increased susceptibility to infections. The overall risk of morbidity and mortality (M&M) in MM patients due to COVID-19 infection is unclear with various studies suggesting case fatality rate of 22% to 29%. Additionally, most of these studies did not stratify patients by their molecular risk profile. METHODS: Here, we aim to investigate the effects of COVID-19 infection with associated risk factors in MM patients and the effectiveness of newly implemented screening and treatment protocols on outcomes. After obtaining institutional review board approvals from each participating institution, we collected data from MM patients diagnosed with SARS-CoV-2 infection from March 1, 2020, to October 30, 2020, at 2 myeloma centers (Levine Cancer Institute & University of Kansas medical center). RESULTS: We identified a total of 162 MM patients who had COVID-19 infection. The majority of patients were males (57%) with a median age of 64 years. Most patients had an associated comorbid condition. Their myeloma disease status and prior autologous stem cell transplant at the time of infection had no impact on hospitalization or mortality. In univariate analysis, chronic kidney disease, hepatic dysfunction, diabetes, and hypertension were associated with an increased risk of hospitalization. In multivariate analysis regarding survival, increased age and lymphopenia were associated with increased COVID-19-related mortality. CONCLUSION: Our study supports the use of infection mitigation measures in all MM patients, and adjustment of treatment pathways in MM patients diagnosed with COVID-19.

With the incorporation of novel agents in earlier lines of therapy, an increasing number of multiple myeloma patients are refractory to traditional classes of drugs. Selinexor in combination with dexamethasone has emerged as a viable option for heavily pretreated triple-class relapsed and refractory multiple myeloma (RRMM). In this systematic review, we analyzed available literature on the role of selinexor in RRMM. The Boston trial demonstrated that selinexor when combined with dexamethasone and bortezomib is associated with a better depth and duration of response without excessive toxicity, compared with bortezomib and dexamethasone alone. Similarly, selinexor in combination with carfilzomib and dexamethasone was found to have a durable response and tolerable safety profile in both carfilzomib-naive and carfilzomib refractory RRMM patients. Selinexor in combination with IMiDs (lenalidomide and pomalidomide) as well as CD38 monoclonal antibodies (daratumumab) also have promising results. Selinexor combination therapy is both safe and effective for patients with pretreated RRMM.

Medical uninsurance (MU) is associated with cancer disparities, particularly among underprivileged and minority sections of the United States. In this cross-sectional study of National Health and Nutritional Examination Survey (NHANES) data from 2013 to 2018, we evaluated sociodemographic attributes of MU disparity in the US cancer population. Those agedâ
≥20 years with a history of cancer and disclosed MU status were included. We calculated the descriptive statistics of the population stratified by insurance type and performed bivariate and multivariate logistic regression models to assess the association of sociodemographic attributes and MU and reported unadjusted (UOR) and adjusted odds ratios (AOR). Among the 1681 participants (US estimated, 25,982,352), 4.3% ± 0.62 were uninsured. Uninsured individuals were 13.5-year younger, largely female, less educated, and non-US born compared to insured individuals. Age (UOR: 0.94, 95% CI: 0.93-0.96), female sex (UOR: 3.53, 95% CI: 1.73-7.19), Hispanics (UOR: 4.30, 95% CI: 2.45-7.54), Assuntos

RESUMO
Light chain deposition disease (LCDD) is a rare hematologic disorder that can affect any organ but predominantly involves the kidneys. Existing literature is limited to case reports and small single-center retrospective series, explaining the lack of any treatment algorithms and management guidelines for patients with this disorder. In this systematic review of literature, we explored the role of standard and high-dose chemotherapy-autologous stem cell transplant for LCDD. A total of 11 studies were identified to evaluate the hematologic and renal responses to various treatment regimens. Autologous stem cell transplant and bortezomib-based regimens appear to have reasonable safety and efficacy for this rare hematologic disorder, albeit some statistical and analytical limitations. Large multicenter retrospective and prospective studies are needed to better elucidate the role of various chemotherapy regimens as well as autologous stem cell transplant for patients with LCDD.
RESUMO
Acute myeloid leukemia (AML) is a heterogeneous hematological malignancy characterized by clonal expansion of myeloid blasts. It is the most common type of acute leukemia in adults, including elderly patients, and has historically been associated with poor outcomes in this age group. Here, we present the case of an 80-year-old woman with newly diagnosed AML with myelodysplasia-related changes. She was treated with a total of five cycles of azacitidine, two cycles as monotherapy followed by three cycles in combination with venetoclax. Therapy was stopped due to cytopenias and declining performance status. Bone marrow aspirate and biopsy immediately following treatment and again approximately four months later did not show any morphologic, immunophenotypic, or cytogenetic evidence of leukemia. The patient's clinical and performance status improved significantly with time. Follow-up labs more than three years following the completion of treatment reveal continued hematologic remission. A short treatment course of azacitidine and venetoclax with close monitoring may lead to durable responses in some patients. Further studies are necessary to determine which patients might be appropriate for treatment suspension or discontinuation while in remission.
RESUMO
BACKGROUND: Recently published randomized controlled trials (RCTs) showed improved overall survival (OS) and progression-free survival (PFS) with the combination of immunotherapy and chemotherapy as compared to chemotherapy alone in advanced non-small cell lung cancer (NSCLC). We aimed to provide a systematic review and meta-analysis of RCTs regarding the efficacy and safety of immunotherapy and chemotherapy combinations for advanced NSCLC. METHODS: On December 23rd, 2021, we searched databases for RCTs that reported PFS and OS as primary outcomes. RESULTS: We included 11 RCTs with 6,386 patients (3,850 in the combination therapy group and 2,536 in the chemotherapy group). Combination therapy was associated with an improvement in PFS (HR: 0.60; 95% CI: 0.54, 0.66; P < 0.00001) andOS (HR: 0.77; 95% CI: 0.68, 0.87; P ≤ 0.0001), compared to chemotherapy. There were no significant differences between both groups in terms of treatment-related adverse events (TRAEs) (RR: 1.07; 95% CI: 0.99, 1.16; P = 0.09). CONCLUSION: The combination of immunotherapy and chemotherapy as first-line treatment for advanced NSCLC significantly improved PFS and OS compared to chemotherapy alone without a significant increase in the overall TRAEs.

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.

Background and objectives: In recent years, immune-checkpoint inhibitors (ICIs) particularly atezolizumab is on the rise in treating advanced malignancies. With its increased clinical use, various electrolyte abnormalities have been reported in the literature. In this review, we have addressed the question of significant electrolyte abnormalities associated with atezolizumab. Materials and methods: Following PRISMA guidelines, we performed a thorough literature search in four databases including PubMed, Cochrane Library, Embase, and Clinicaltrials.gov. We included only randomized controlled trials from 2010 till March 2021. After a comprehensive screening of 1587 articles, we selected 14 articles for our review and tabulated the results. Following MeSH terms were used: "electrolyte abnormalities", "immune checkpoint inhibitors", "atezolizumab". Results: Non-small cell lung cancer (n = 1270) and metastatic urothelial carcinoma (n = 1164) were the most common malignancies among 3160 patients. The most common electrolyte abnormality was hypomagnesemia (4.7%). Hyponatremia, hypophosphatemia, hypercalcemia and hypokalemia were found in 2.3%, 0.63%, 0.25% and 0.06% patients respectively. For patients taking atezolizumab, hypomagnesemia was most frequently found in non-small cell lung carcinoma patients (9.4%), while urothelial metastatic carcinoma patients most commonly had hyponatremia (5.15%). Hypokalemia though insignificant was observed only in patients with metastatic renal cell carcinoma (2.85%). Conclusion: Since the use of atezolizumab is on the rise for the treatment of various cancers, more studies need to be conducted to better understand its safety and toxicity profile.
RESUMO
Hemophagocytic lymphohistiocytosis (HLH) is a rare but life-threatening disorder of the immune system. While familial HLH is usually seen in children, secondary HLH is more common in adults. Secondary HLH is associated with a wide variety of underlying conditions including infections, malignancy and autoimmune disorders. While HLH 94/04 protocol-based chemotherapy can be used for initial treatment, allogeneic hematopoietic stem cell transplant (allo-HSCT) remains the only potentially curative treatment modality for this disorder. In this systematic review, we analyzed available literature on the role of allo-HSCT in adolescent and adult patients using PubMed, Cochrane, Embase and ClinicalTrials.gov. A total of 11 retrospective studies evaluated the role of allo-HSCT for HLH. Allo-HSCT, when compared to non-HSCT approach, appears to be associated with reasonable efficacy and acceptable safety for adolescent and adult patients with HLH.

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.

Secondary immune-related hemophagocytic lymphohistiocytosis is a rare but life-threatening complication of immune checkpoint inhibitors. HLH-2004 and HLH-1994 guidelines originally developed for primary HLH are the only available guidelines. It has proven to have a good prognosis if diagnosed promptly with discontinuation of immunotherapy and treated with corticosteroid monotherapy.
RESUMO
Carfilzomib (CFZ) is a proteasome inhibitor currently approved for the treatment of relapsed and refractory multiple myeloma (RRMM). Multiple trials are ongoing to evaluate its efficacy and safety in newly diagnosed multiple myeloma (NDMM). The use of CFZ-based two- or three-drug combination regimens as induction for the management of NDMM is an emerging approach. CFZ-based regimens include combinations of immunomodulators, alkylating agents, and monoclonal antibodies along with dexamethasone. In this review, we assess the efficacy and toxicity of CFZ-based regimens in NDMM. We reviewed a total of 27 studies (n=4538 patients) with overall response rates (ORR) ranging between 80% and 100%. Studies evaluating the combination of CFZ with daratumumab reported an ORR of approximately 100%. Achievement of minimal residual disease (MRD) negativity, measured by multi-parameter flow cytometry (MPFC), ranged between 60% and 95% in 4 (n=251) out of 6 studies that measured MRD-negativity. The interim results of the ENDURANCE trial failed to show superior efficacy and progression-free survival (PFS) of carfilzomib-lenalidomide when compared to bortezomib-lenalidomide combination, albeit with a lower incidence of neuropathy. Hematological toxicity was the most common adverse event observed with these regimens, and the most common non-hematological adverse events were related to cardiovascular and electrolyte disturbances. We need to further evaluate the role of CFZ in NDMM by conducting more Phase III trials with different combinations.
RESUMO
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.
RESUMO
Biomarker-driven targeted therapies have been an area of exploration for innovative therapeutic options in oncology. B-cell lymphoma-2 (BCL-2) protein is an anti-apoptotic protein expressed on the clonal plasma cells in patients with multiple myeloma (MM). MM subsets with t (11;14) have overexpression of BCL-2 and can benefit from venetoclax (VEN) when used either alone or in combination with other chemotherapeutic agents with an overall response rate (ORR) ranging from 40% to 100%. The most commonly reported grade ≥ 3 adverse effects include cytopenias and gastrointestinal side effects. This review highlights the meaningful efficacy and tolerable safety of VEN monotherapy and its combination regimens in the treatment of relapsed refractory MM.
RESUMO
Belantamab mafodotin (belamaf), an antibody-drug conjugate approved for the treatment of relapsed and refractory multiple myeloma (RRMM), is an anti B-cell maturation antigen (BCMA) agent. DREAMM-1, a first in-human trial of belamaf, reported several ocular toxicities requiring dose adjustments, dose delays and treatment discontinuations. In DREAMM-1, 53% of patients in part-1 and 63% of patients in part-2 had ocular toxicity. Similarly, 73% of patients in DREAMM-2 had keratopathy (71% in 2.5 mg/kg versus 75% in 3.4 mg/kg) with the most common symptoms being blurred vision and dry eyes. Ocular toxicity of belamaf is attributed to microtubule-disrupting monomethylauristatin-F (MMAF), a cytotoxic payload of the drug that causes an off-target damage to the corneal epithelial cells. Ocular adverse events (AEs) of belamaf are more frequent at higher doses compared with lower doses. Higher belamaf dose, history of dry eyes and soluble BCMA are associated with increased risk of corneal toxicity. Absence of ocular symptoms does not exclude the possibility of belamaf-induced ocular toxicity, so patients need slit lamp and Snellen visual acuity testing to detect microcytic-like epithelial changes and visual decline. Corticosteroid eyes drops for 4-7 days prior to belamaf dose do not prevent ocular AEs and may cause steroid-related AEs instead. Keratopathy and Visual Acuity scale (KVA) is recommended to document the severity of belamaf-induced ocular toxicity and make treatment adjustments. Management of toxicity includes dosage modifications, treatment interruption or discontinuations and preservative-free artificial tears along with close ophthalmology and hematology-oncology follow-ups.
RESUMO
Metastasis of renal cell carcinoma to the heart is a rare event. Herein we present a case of renal cell carcinoma presenting with progressive fatigue, abdominal pain, and weight loss. Imaging studies revealed complex renal mass with extension to right atrium and histopathology confirmed the metastatic renal cell carcinoma.
RESUMO
The most common etiology of malignant brain tumors is metastatic lesions. They usually present as multiple lesions at the gray-white matter junction. However, they can unconventionally present as a single space-occupying lesion mimicking meningioma.
RESUMO
Palmar-plantar erythrodysesthesia (PPE) is an uncommon adverse event with paclitaxel. We report a case of PPE due to paclitaxel to create awareness and review management strategies. A 61-year-old female with locally advanced lobular breast cancer was started on neoadjuvant chemotherapy with four cycles of dose-dense doxorubicin and cyclophosphamide. She completed these chemotherapy cycles uneventfully and was started on weekly paclitaxel (80mg/m2) with a gap of two weeks. After receiving the sixth dose of paclitaxel, the patient presented with erythema, swelling, and discomfort of her hands and feet, interfering with her quality of life due to difficulty in carrying out daily routine activities. The changes were acute, occurred within a few days after the sixth dose of paclitaxel, and were consistent with PPE grade 2. Paclitaxel was discontinued, and the patient was switched to docetaxel every three weeks for two cycles. She used emollients and moisturizing creams for her local symptoms, after stopping paclitaxel, erythema, swelling, and discomfort of her hands and feet resolved within two weeks. She did not have a recurrence of these symptoms with docetaxel. Paclitaxel can cause PPE. Its incidence in the literature might be underreported. Discontinuation of paclitaxel can reverse skin toxicity and improve patient's quality of life.
