Clinician and administrator perspectives on outpatient administration of ciltacabtagene autoleucel in relapsed or refractory multiple myeloma.

Introduction: Chimeric antigen receptor (CAR) T-cell therapy (CAR T therapy) is a treatment option for patients with relapsed or refractory multiple myeloma that has led to unprecedented treatment outcomes. Among CAR T therapies available, ciltacabtagene autoleucel (cilta-cel) is a good candidate for outpatient administration due to its generally predictable safety profile. There are multiple advantages of outpatient administration of cilta-cel, including reduced healthcare burden, expanded access, and patient autonomy.

The Impact of Outpatient versus Inpatient Administration of CAR-T Therapies on Clinical, Economic, and Humanistic Outcomes in Patients with Hematological Cancer: A Systematic Literature Review.

Although chimeric antigen receptor (CAR)-T cell therapies are typically administered in the inpatient setting, outpatient administration is rapidly expanding. However, there is limited summarized evidence comparing outcomes between outpatient and inpatient administration. This systematic literature review aims to compare the safety, efficacy, quality of life (QoL), costs, and healthcare resource utilization (HCRU) outcomes in patients with hematological cancer who are administered CAR-T therapy in an outpatient versus an inpatient setting.

Efficacy and safety of cilta-cel in patients with progressive multiple myeloma after exposure to other BCMA-targeting agents.

B-cell maturation antigen (BCMA)-targeting therapies, including bispecific antibodies (BsAbs) and antibody-drug conjugates (ADCs), are promising treatments for multiple myeloma (MM), but disease may progress after their use. CARTITUDE-2 is a phase 2, multicohort study evaluating the safety and efficacy of cilta-cel, an anti-BCMA chimeric antigen receptor T therapy, in various myeloma patient populations. Patients in cohort C progressed despite treatment with a proteasome inhibitor, immunomodulatory drug, anti-CD38 antibody, and noncellular anti-BCMA immunotherapy.

Extracellular Vesicle and Particle Biomarkers Define Multiple Human Cancers.

There is an unmet clinical need for improved tissue and liquid biopsy tools for cancer detection. We investigated the proteomic profile of extracellular vesicles and particles (EVPs) in 426 human samples from tissue explants (TEs), plasma, and other bodily fluids. Among traditional exosome markers, CD9, HSPA8, ALIX, and HSP90AB1 represent pan-EVP markers, while ACTB, MSN, and RAP1B are novel pan-EVP markers.

Treatment and revaccination of children with paraneoplastic opsoclonus-myoclonus-ataxia syndrome and neuroblastoma: The Memorial Sloan Kettering experience.

Objective: To review the treatment and revaccination of neuroblastoma-associated opsoclonus-myoclonus-ataxia syndrome (OMAS) patients at Memorial Sloan Kettering Cancer Center (MSK).

Procedure: Institutional Review Board approval was obtained for this retrospective study of patients with neuroblastoma-associated OMAS followed at MSK from 2000 to 2016.

Results: Fourteen patients (nine female) were 9-21 (median 17) months old at diagnosis of neuroblastoma and OMAS syndrome.

Patterns of relapse for children with localized intracranial ependymoma.

We examined patterns of relapse and prognostic factors in children with intracranial ependymoma. Records of 82 children diagnosed with localized intracranial ependymoma were reviewed. 52% first presented to our institution after relapse.

Long-term outcomes of adult medulloblastoma patients treated with radiotherapy.

Medulloblastoma (MB) is rare in adults and treatment guidelines are consequently not well-established. Few modern series have reported long-term follow-up and treatment sequelae. We examined long-term outcomes of adult MB patients at one institution.

A phase II study of radioimmunotherapy with intraventricular I-3F8 for medulloblastoma.

Background: High-risk and recurrent medulloblastoma (MB) is associated with significant mortality. The murine monoclonal antibody 3F8 targets the cell-surface disialoganglioside GD2 on MB. We tested the efficacy, toxicity, and dosimetry of compartmental radioimmunotherapy (cRIT) with intraventricular I-labeled 3F8 in patients with MB on a phase II clinical trial.

Reduced-volume radiotherapy for patients with localized intracranial nongerminoma germ cell tumors.

Craniospinal irradiation is standard radiotherapy (RT) for localized intracranial nongerminoma germ cell tumors (NGGCT). Given its toxicity, there is interest in using smaller fields. We examined outcomes of NGGCT patients receiving reduced-volume RT at a single institution.

A phase I study of single-agent perifosine for recurrent or refractory pediatric CNS and solid tumors.

The PI3K/Akt/mTOR signaling pathway is aberrantly activated in various pediatric tumors. We conducted a phase I study of the Akt inhibitor perifosine in patients with recurrent/refractory pediatric CNS and solid tumors. This was a standard 3+3 open-label dose-escalation study to assess pharmacokinetics, describe toxicities, and identify the MTD for single-agent perifosine.

A phase I study of perifosine with temsirolimus for recurrent pediatric solid tumors.

Background: The PI3K/AKT/mTOR pathway is aberrantly activated in many pediatric solid tumors including gliomas and medulloblastomas. Preclinical data in a pediatric glioma model demonstrated that the combination of perifosine (AKT inhibitor) and temsirolimus (mTOR inhibitor) is more potent at inhibiting the axis than either agent alone. We conducted this study to assess pharmacokinetics and identify the maximum tolerated dose for the combination.

Medulloblastoma.

Medulloblastoma accounts for nearly 10% of all childhood brain tumors. These tumors occur exclusively in the posterior fossa and have the potential for leptomeningeal spread. Treatment includes a combination of surgery, radiation therapy (in patients >3 years old).

Extraneural metastases of medulloblastoma: desmoplastic variants may have prolonged survival.

Background: Extraneural metastases from CNS medulloblastoma are rare and poorly described. The purpose of this study is to describe the clinical and radiological characteristics of a large single institution series of patients with medulloblastoma who developed extraneural metastases.

Procedure: We retrospectively reviewed a departmental database over a 20 year period for all patients with medulloblastoma who developed extraneural metastases.

Patterns of care in adult medulloblastoma: results of an international online survey.

The literature on medulloblastoma in adults is generally limited to case reports and retrospective series, and there is no accepted standard of care. The Cooperative Trials Group for Neuro-Oncology (COGNO) sought to determine the range and consistency of clinicians' approaches to management as a basis for future trials. We aimed to identify current treatment strategies for adult medulloblastoma through an online survey launched at the 2012 Society of Neuro-Oncology meeting and by email invitation.

A case of mannitol hypersensitivity.

Mannitol is used for increased intracranial pressure and prevention of nephrotoxicity. We present a case report of a patient who experienced an anaphylactic response to mannitol and review the literature.

Treatment Options for Medulloblastoma and CNS Primitive Neuroectodermal Tumor (PNET).

Medulloblastoma and central nervous system (CNS) primitive neuroectodermal tumor (PNET) are primary pediatric brain tumors that require multidisciplinary therapies. Although often treated similarly in clinical trials, they are biologically different diseases. Even within medulloblastomas and CNS PNETs, there are molecularly distinct subgroups with differing presentations and prognoses.

Efficacy and safety of bevacizumab in active brain metastases from non-small cell lung cancer.

Bevacizumab is effective for the treatment of non-small cell lung cancer (NSCLC). Ongoing trials are exploring the safety of bevacizumab in patients with inactive, previously treated brain metastases. However, bevacizumab safety and efficacy in the treatment of active brain metastases is unknown.

The molecular basis of pyruvate carboxylase deficiency: mosaicism correlates with prolonged survival.

Pyruvate carboxylase (PC) deficiency (OMIM, 266150) is a rare autosomal recessive disease. The revised PC gene structure described in this report consists of 20 coding exons and four non-coding exons at the 5'-untranslated region (5'-UTR). The gene codes for three transcripts due to alternative splicing: variant 1 (NM_000920.

Neurotoxicity of chemotherapeutic and biologic agents in children with cancer.

The sequelae of treatment modalities used to treat childhood cancer are of increasing clinical importance. In children with pediatric malignancies, the full impact of such sequelae may not be apparent until years after treatment. The earlier recognition of these neurotoxicities could possibly alter the course of a treatment or facilitate interventions to improve quality of life.
