RESUMO

Breast radiologists are increasingly seeing patients with axillary adenopathy related to COVID-19 vaccination. Vaccination can cause levels I-III axillary as well as cervical lymphadenopathy. Appropriate management of vaccine-related adenopathy may vary depending on clinical context. In patients with current or past history of malignancy, vaccine-related adenopathy can be indistinguishable from nodal metastasis. This article presents imaging findings of oncology patients with adenopathy seen in the axilla or neck on cross-sectional imaging (breast MRI, CT, or PET-CT) after COVID-19 vaccination. Management approach and rationale is discussed, along with consideration on strategies to minimize false positives in vaccinated cancer patients. Time interval between vaccination and adenopathy seen on breast MRI, CT, or PET-CT is also reported.

RESUMO

Standard of care (SOC) chimeric antigen receptor (CAR) T-cell therapies such as axicabtagene ciloleucel (axi-cel) and tisagenlecleucel (tisa-cel) are associated with multisystem toxicities. There is limited information available about cardiovascular (CV) events associated with SOC axi-cel or tisa-cel. Patients with CV comorbidities, organ dysfunction, or lower performance status were often excluded in the clinical trials leading to their FDA approval. An improved understanding of CV toxicities in the real-world setting will better inform therapy selection and management of patients receiving these cellular therapies. Here, we retrospectively reviewed the characteristics and outcomes of adult patients with relapsed/refractory large B-cell lymphoma treated with SOC axi-cel or tisa-cel. Among the 165 patients evaluated, 27 (16%) developed at least one 30-day Major adverse CV event (MACE). Cumulatively, these patients experienced 21 arrhythmias, 4 exacerbations of heart failure/cardiomyopathy, 4 cerebrovascular accidents, 3 myocardial infarctions (MI), and one patient died due to MI. Factors significantly associated with an increased risk of 30-d MACE included age ≥60 years, an earlier start of cytokine release syndrome (CRS), CRS ≥ grade 3, long duration of CRS, and use of tocilizumab. After a median follow-up time of 16.2 months (range 14.3-19.1), the occurrence of 30-d MACE was not significantly associated with progression-free survival (PFS) or with overall survival (OS). Our results suggest that the occurrence of 30-d MACE is more frequent among patients who are elderly, with early, severe, and prolonged CRS. However, with limited followup, larger prospective studies are needed, and multidisciplinary management of these patients is recommended.

RESUMO

OBJECTIVES: There is little research on the patient experience of symptom burden from CAR T-cell therapy, and no validated measure specific to the symptoms of CAR T-cell therapy currently exists. The purpose of this study was to identify symptoms experienced and to determine the content domain for a patient-reported outcome (PRO) measuring symptom burden for patients who had received standard of care CAR T-cell therapy for advanced B-cell lymphoid malignancies. DATA SOURCES: Semi-structured qualitative interviews were conducted with a sample of 21 patients who had received CAR T-cell therapy. Content analysis was used to define the symptom burden content domain. CONCLUSION: Sixty-two percent of patients were interviewed within 3 months of therapy; 81.0% experienced cytokine release syndrome and 28.6% experienced neurotoxicity. Content analysis found 31 symptoms related to disease and treatment. The most common disease-related symptom identified by patients was pain (43%). The most common symptoms identified by patients as related to CAR T-cell therapy included fatigue (tiredness) (62%), lack of appetite (29%), headache (29%), chills or feeling cold (24%), and feeling confused (24%). The qualitative analysis also confirmed that symptoms interfere with daily activities, work, walking, relationships with others, mood, and enjoyment of life. IMPLICATIONS FOR NURSING PRACTICE: Patients who receive standard CAR T-cell therapy experience numerous symptoms related to disease and CAR T-cell therapy, including symptoms related to the T-cell infusion. Symptoms may result in interference with daily activities, relationships, treatment adherence, and mood. Oncology nurses should be aware of and assess symptom related to CAR T-cell therapy.

RESUMO

This article reports a fatal case of human herpesvirus 6 (HHV-6) myelitis following CD19-targeted chimeric antigen receptor T-cell therapy. Infection from HHV-6 reactivation after haematopoietic stem cell transplant is established, and outside of this population is limited to case reports. The patient developed cytokine release syndrome and immune effector cell-associated neurotoxicity syndrome that responded to corticosteroids both clinically and on imaging. Subsequently, ascending flaccid paralysis developed, leading to neuromuscular respiratory failure and, ultimately, death. Disease progression was refractory to foscarnet and multiple immunomodulating agents. HHV-6 should be considered in patients with encephalitis and myelitis after adoptive T-cell therapy.

RESUMO

The SCHOLAR-1 international retrospective study highlighted poor clinical outcomes and survival among patients with refractory large B-cell lymphoma (LBCL) treated with conventional chemotherapy. Axicabtagene ciloleucel (axi-cel), an autologous anti-CD19 chimeric antigen receptor (CAR) T-cell therapy, demonstrated durable responses in patients with refractory LBCL in the pivotal phase 1/2 ZUMA-1 study (NCT02348216). Here, we compared SCHOLAR-1 with the 2-year outcomes of ZUMA-1. Prior to comparison of clinical outcomes, propensity scoring (based on a broad set of prognostic covariates) was used to create balance between ZUMA-1 and SCHOLAR-1 patients. In the pivotal phase 2 portion of ZUMA-1, 101 patients received axi-cel and were evaluable for response and survival. In SCHOLAR-1, 434 and 424 patients were evaluable for response and survival, respectively. ZUMA-1 patients were more heavily pretreated than were SCHOLAR-1 patients. The median follow-up was 27.1 months in ZUMA-1. The objective response rate (ORR) and complete response rate were 83% and 54% in ZUMA-1 vs 34% and 12% in SCHOLAR-1, respectively. The 2-year survival rate was 54% in ZUMA-1 and 20% in SCHOLAR-1, and a 73% reduction in the risk of death was observed in ZUMA-1 vs SCHOLAR-1. These results were consistent with those of an additional standardization analysis in which strata were limited to 2 prognostic factors (refractory categorization and presence/absence of stem cell transplant after refractoriness to chemotherapy) to conserve sample size. Despite the limitations of a nonrandomized analysis, these results indicate that axi-cel produces durable responses and a substantial survival benefit vs non-CAR T-cell salvage regimens for patients with refractory LBCL.

RESUMO

PI3-kinase p110δ is mainly expressed in lymphocytes and is an attractive therapeutic target in B cell lymphomas. Targeting p110ß may further suppress tumor growth and overcome escape mechanisms. KA2237 is an oral, potent, dual p110ß/p110δ inhibitor. In preclinical studies, KA2237 inhibited p110ß- and p110δ-dependent AKT activation and suppressed proliferation of diverse hematological and epithelial tumors. Twenty-one patients received KA2237 in a first-in-human phase I study (NCT02679196; diffuse large B cell, n = 8; follicular, n = 5; mantle cell, n = 3; chronic lymphocytic leukemia/small lymphocytic lymphoma, n = 3; marginal zone, n = 1; Waldenstrom's, n = 1). Median age 69; median prior therapies 3. Eighty-six percent of patients experienced treatment-related adverse events (TRAEs). Forty-three percent of patients experienced grade ≥3 TRAEs, with rash (n = 3), pneumonia (n = 3), transaminitis (n = 2), and pneumonitis (n = 2) being most common. Thirty-three percent discontinued treatment due to adverse events. KA2237 induced objective responses in indolent and aggressive lymphoma (overall response rate 37%; complete response n = 4, partial response n = 3).

RESUMO

Many patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) will not respond to platinum-containing salvage chemotherapy. Predicting treatment failure earlier could help clinicians minimize chemotherapy toxicities for non-responders in favor of other treatments. We conducted a pilot study where 2 early PET/CTs were obtained on days 4 (D4) and 21 (D21) of cycle 1 (C1) of salvage therapy for DLBCL. Twenty-five patients were enrolled and have evaluable data. Ten (40%) had an unplanned therapy change after C1 and before end-of-treatment (EOT) evaluation due to treatment failure on early PET/CT as interpreted by the treating physician. Early PET/CT response at D4 or D21 was not associated with EOT response in evaluable patients. Disease specific survival was longer for patients with a persistent response on both D4 and D21 (p = 0.042). Early PET/CT may predict salvage chemotherapy failure and could inform future clinical trials investigating early therapy change to non-chemotherapy treatments.

RESUMO

The Endothelial Activation and Stress Index (EASIX) score, defined as [(creatinine × lactate dehydrogenase [LDH])/platelets], is a marker of endothelial activation that has been validated in the allogeneic hematopoietic stem cell transplant setting. Endothelial activation is one of the mechanisms driving immune-mediated toxicities in patients treated with chimeric antigen receptor-T (CAR-T)-cell therapy. This study's objective was to evaluate the association between EASIX and other laboratory parameters collected before lymphodepletion and the subsequent onset of cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) those patients. Toxicity data were collected prospectively on 171 patients treated with axicabtagene ciloleucel (axi-cel) for large B-cell lymphoma (LBCL). CRS grades 2 to 4 were diagnosed in 81 (47%) patients and ICANS grades 2 to 4 in 84 (49%). EASIX combined with ferritin (EASIX-F) identified 3 risk groups with CRS grades 2 to 4 cumulative incidence of 74% (hazards ratio [HR], 4.8; 95% confidence interval [CI], 2.1-11; P < .001), 49% (HR, 2.3; 95% CI, 1.02-5; P = .04), and 23% (reference), respectively. EASIX combined with CRP and ferritin (EASIX-FC) identified 3 risk groups with an ICANS grade 2 to 4 cumulative incidence of 74% (HR, 3.6; 95% CI, 1.9-6.9; P < .001), 51% (HR, 2.1; 95% CI, 1.1-3.9; P = .025), and 29% (reference). Our results indicate that common laboratory parameters before lymphodepletion correlate with CAR-T-related toxicities and can help support clinical decisions, such as preemptive toxicity management, hospitalization length, and proper setting for CAR-T administration.

RESUMO

Chimeric antigen receptor (CAR)-T cell therapy has revolutionized treatment of relapsed/refractory non-Hodgkin lymphoma (NHL). However, since 36-60% of patients relapse, early response prediction is crucial. We present a novel population quantitative systems pharmacology model, integrating literature knowledge on physiology, immunology, and adoptive cell therapy together with 133 CAR-T cell phenotype, 1943 cytokine, and 48 metabolic tumor measurements. The model well described post-infusion concentrations of four CAR-T cell phenotypes and CD19+ metabolic tumor volume over 3 months after CAR-T cell infusion. Leveraging the model, we identified a low expansion subpopulation with significantly lower CAR-T cell expansion capacities amongst 19 NHL patients. Together with two patient-/therapy-related factors (autologous stem cell transplantation, CD4+/CD8+ T cells), the low expansion subpopulation explained 2/3 of the interindividual variability in the CAR-T cell expansion capacities. Moreover, the low expansion subpopulation had poor prognosis as only 1/4 of the low expansion subpopulation compared to 2/3 of the reference population were still alive after 24 months. We translated the expansion capacities into a clinical composite score (CCS) of 'Maximum naïve CAR-T cell concentrations/Baseline tumor burden' ratio and propose a CCSTN-value > 0.00136 (cells·µL-1·mL-1 as predictor for survival. Once validated in a larger cohort, the model will foster refining survival prediction and solutions to enhance NHL CAR-T cell therapy response.

RESUMO

Chimeric antigen receptor (CAR) T cell therapy is being increasingly used to treat patients with advanced hematologic malignancies; however, the symptoms related to standard of care CAR T cell therapy during the first year after treatment have not been assessed using patient-reported outcome (PRO) measurements. This study aimed to quantify patients' perspectives of symptom burden and functional status using PROs during the first year after CAR T cell therapy for hematologic malignancies, especially in patients who experienced grade 2-4 toxicities. Sixty patients were enrolled in this observational cross-sectional study at any time during their first 12 months post-treatment. All 60 had received CAR T cell therapy as standard of care at MD Anderson Cancer Center in 2019. PROs were measured using the MD Anderson Symptom Inventory (MDASI), the PROs Measurement Information System 29 (PROMIS-29), the global health tool EQ5D-5L, and the single-item health-related quality of life scale (HRQoL). Twenty-two additional symptoms related to CAR T cell therapy, as identified by an expert panel, were also evaluated. CAR T cell therapy-related toxicities were rated according to the ASTCT consensus grading criteria. The majority of patients (52 of 60; 87%) received axicabtagene ciloleucel (Yescarta). One-third of the patients developed grade 2-4 cytokine release syndrome or neurotoxicity. The first 90 days after infusion represented the most symptomatic period, in which >10% of patients rated 18 symptoms as severe (ie, MDASI symptom score of 7 to 10 on scale of 0 to 10), strongly indicating the need for effective symptom management. Physical functioning, measured by interference on the "general activity" item on the MDASI and this domain on the PROMIS-29, were significantly worse in patients who underwent therapy during the first 30 days compared with those who underwent therapy over 90 days (all P < .05 with the Hochberg step-up procedure), whereas the EQ5D-5L and single-item HRQoL did not detect such differences. Compared with patients who had mild cytokine release syndrome or neurotoxicity (grade 0-1), patients who developed grade 2-4 toxicities persistently reported multiple severe symptoms after 30 days following therapy (all P < .05). Furthermore, although using a different recall period, patient-reported scores on several PROMIS-29 domains were significantly correlated with the scores of corresponding MDASI symptom items. This real-world quantitative PRO symptoms study provides evidence of unique profiles of the physical, psychological, and cognitive symptom burden in patients undergoing CAR T cell therapy that varies within the first year after infusion and demonstrates differences among PRO measurement scales. These results support the need for validation of fit-for-purpose PRO measurements for routinely monitoring symptom and toxicity burdens in CAR T cell therapy care settings.

RESUMO

This study aimed to assess the prognostic value of baseline disease distribution for patients with the secondary central nervous system (CNS) diffuse large B-cell lymphoma (DLBCL) treated with chemotherapy and radiation (RT). 44 patients with secondary CNS DLBCL were reviewed. Twenty patients had leptomeningeal disease (LMD), and 24 had localized/targetable disease (LTD). Of 8 patients who received stem cell transplantation (SCT) after RT, 6 had LTD with a complete or partial response after RT. Median time to CNS relapse after RT was 10.1 months; 3/24 patients with LTD and 5/15 with LMD had CNS relapse. The median overall survival (OS) was 8 and 20 months for patients with LMD and LTD, respectively (p = 0.20). On multivariable analysis, LTD, receipt of SCT, and response after RT were associated with better OS and CNS-disease-free survival. Patients with localized secondary CNS DLBCL may benefit from RT serving as a bridge to SCT.

RESUMO

A paradigm shift has recently occurred in the field of cancer therapeutics. Traditional anticancer agents, such as chemotherapy, radiotherapy and small-molecule drugs targeting specific signalling pathways, have been joined by cellular immunotherapies based on T cell engineering. The rapid adoption of novel, patient-specific cellular therapies builds on scientific developments in tumour immunology, genetic engineering and cell manufacturing, best illustrated by the curative potential of chimeric antigen receptor (CAR) T cell therapy targeting CD19-expressing malignancies. However, the clinical benefit observed in many patients may come at a cost. In up to one-third of patients, significant toxicities occur that are directly associated with the induction of powerful immune effector responses. The most frequently observed immune-mediated toxicities are cytokine release syndrome and immune effector cell-associated neurotoxicity syndrome. This Review discusses our current understanding of their pathophysiology and clinical features, as well as the development of novel therapeutics for their prevention and/or management.

RESUMO

CAR T-cell therapy has revolutionized the treatment approach to patients with relapsed/refractory hematologic malignancies; however, there continues to be opportunity for improvement in treatment toxicity as well as response durability. Radiation therapy can play an important role in combined modality treatments for some patients undergoing CAR T-cell therapy in various clinical settings. In this review, we discuss the current evidence for RT in the setting of CAR T-cell therapy for patients with hematologic malignancies and propose potential opportunities for future investigation of RT and CAR T-cell treatment synergy. Future research frontiers include investigation of hypotheses including radiation priming of CAR T-cell mediated death, pre-CAR T-cell tumor debulking with radiation therapy, and selection of high risk patients for early radiation salvage after CAR T cell therapy.

RESUMO

Inflammation has long been associated with cancer initiation and progression; however, how inflammation causes immune suppression in the tumor microenvironment and resistance to immunotherapy is not well understood. In this study, we show that both innate proinflammatory cytokine IL-1α and immunotherapy-induced IL-1α make melanoma resistant to immunotherapy. In a mouse melanoma model, we found that tumor size was inversely correlated with response to immunotherapy. Large tumors had higher levels of IL-1α, Th2 cytokines, polymorphonuclear myeloid-derived suppressor cells (PMN-MDSCs), and regulatory T cells but lower levels of IL-12, Th1 cytokines, and activated T cells. We found that therapy with adenovirus-encoded CD40L (rAd.CD40L) increased tumor levels of IL-1α and PMN-MDSCs. Blocking the IL-1 signaling pathway significantly decreased rAd.CD40L-induced PMN-MDSCs and their associated PD-L1 expression in the tumor microenvironment and enhanced tumor-specific immunity. Similarly, blocking the IL-1 signaling pathway improved the antimelanoma activity of anti-PD-L1 Ab therapy. Our study suggests that blocking the IL-1α signaling pathway may increase the efficacy of immunotherapies against melanoma.

RESUMO

Cancer immunotherapies are associated with remarkable therapeutic response rates but also with unique and severe toxicities, which potentially result in rapid deterioration in health. The number of clinical applications for novel immune effector-cell therapies, including chimeric antigen receptor (CAR)-expressing cells, and other immunotherapies, such as immune-checkpoint inhibitors, is increasing. In this Consensus Statement, members of the Pediatric Acute Lung Injury and Sepsis Investigators (PALISI) Network Hematopoietic Cell Transplantation-Cancer Immunotherapy (HCT-CI) Subgroup, Paediatric Diseases Working Party (PDWP) of the European Society of Blood and Marrow Transplantation (EBMT), Supportive Care Committee of the Pediatric Transplantation and Cellular Therapy Consortium (PTCTC) and MD Anderson Cancer Center CAR T Cell Therapy-Associated Toxicity (CARTOX) Program collaborated to provide updated comprehensive recommendations for the care of children, adolescents and young adults receiving cancer immunotherapies. With these recommendations, we address emerging toxicity mitigation strategies, we advocate for the characterization of baseline organ function according to age and discipline-specific criteria, we recommend early critical care assessment when indicated, with consideration of reversibility of underlying pathology (instead of organ failure scores) to guide critical care interventions, and we call for researchers, regulatory agencies and sponsors to support and facilitate early inclusion of young patients with cancer in well-designed clinical trials.

RESUMO

Corticosteroids are commonly used for the management of severe toxicities associated with chimeric antigen receptor (CAR) T-cell therapy. However, it remains unclear whether their dose, duration, and timing may affect clinical efficacy. Here, we determined the impact of corticosteroids on clinical outcomes in patients with relapsed or refractory large B-cell lymphoma treated with standard of care anti-CD19 CAR T-cell therapy. Among 100 patients evaluated, 60 (60%) received corticosteroids for management of CAR T-cell therapy-associated toxicities. The median cumulative dexamethasone-equivalent dose was 186 mg (range, 8-1803) and the median duration of corticosteroid treatment was 9 days (range, 1-30). Corticosteroid treatment was started between days 0 and 7 in 45 (75%) patients and beyond day 7 in 15 (25%). After a median follow-up of 10 months (95% confidence interval, 8-12 months), use of higher cumulative dose of corticosteroids was associated with significantly shorter progression-free survival. More importantly, higher cumulative dose of corticosteroids, and prolonged and early use after CAR T-cell infusion were associated with significantly shorter overall survival. These results suggest that corticosteroids should be used at the lowest dose and for the shortest duration and their initiation should be delayed whenever clinically feasible while managing CAR T-cell therapy-associated toxicities.
