Ethical Challenges with Multiple Myeloma BCMA Chimeric Antigen Receptor T Cell Slot Allocation: A Multi-Institution Experience.

Chimeric antigen receptor T cell (CAR-T) therapies are Food and Drug Administration (FDA)-approved for patients with triple refractory multiple myeloma (MM). Real-world access to CAR-T therapy remains challenging owing to supply chain limitations impacting manufacturing. The goal of this study was to evaluate the extent of this issue and how major centers are handling the challenges of CAR-T manufacturing slot allocation.

The Application of NextGen Sequencing in the Diagnosis of Myeloid Neoplasms in Myeloma Patients With Cytopenia.

Background: Multiple myeloma (MM) is an incurable clonal neoplasm that usually requires long-term treatment, which may result in secondary cytopenia(s) and myeloid neoplasms. We investigated the landscape of mutations detected by NextGen sequencing (NGS) in myeloma patients with cytopenia.

Methods And Materials: MM patients (n = 196) with cytopenia(s) and NGS results were identified and divided into 4 groups: 1) patients with myeloma only and no myeloid neoplasms; 2) patients with myeloid neoplasms but no myeloma; 3) patients with concurrent myeloma and myeloid neoplasms; and 4) patients with no myeloma or myelodysplasia.

Hybrid models for lung nodule malignancy prediction utilizing convolutional neural network ensembles and clinical data.

: Due to the high incidence and mortality rates of lung cancer worldwide, early detection of a precancerous lesion is essential. Low-dose computed tomography is a commonly used technique for screening, diagnosis, and prognosis of non-small-cell lung cancer. Recently, convolutional neural networks (CNN) had shown great potential in lung nodule classification.

Reproducibility of F18-FDG PET radiomic features for different cervical tumor segmentation methods, gray-level discretization, and reconstruction algorithms.

Site-specific investigations of the role of radiomics in cancer diagnosis and therapy are emerging. We evaluated the reproducibility of radiomic features extracted from Flourine-fluorodeoxyglucose ( F-FDG) PET images for three parameters: manual versus computer-aided segmentation methods, gray-level discretization, and PET image reconstruction algorithms. Our cohort consisted of pretreatment PET/CT scans from 88 cervical cancer patients.

The guinea pig syndrome: improving clinical trial participation among thoracic patients.

Background: The purpose of the study was to examine lung cancer patients' knowledge, attitudes, and behavior regarding clinical trials and to develop an effective intervention for increasing patient knowledge and awareness of clinical trials for lung cancer patients.

Methods: Qualitative semistructured, in-depth interviews were conducted with (1) new patients who had not yet interacted with their physicians, (2) existing patients who had participated in a clinical trial, and (3) existing patients who had not been offered a trial. Findings from the interviews led to the creation of a letter that was sent to all new patients before their first appointment, explaining that offering a clinical trial at this hospital was the norm, to expect this discussion, and the option of standard treatment was always available.

Inhibition of mitogenesis in Balb/c-3T3 cells by Trichostatin A. Multiple alterations in the induction and activation of cyclin-cyclin-dependent kinase complexes.

Trichostatin A (TSA), a global repressor of histone deacetylase activity, inhibits the proliferation of a number of cell types. However, the identification of the mechanisms underlying TSA-mediated growth arrests has remained elusive. In order to resolve in more detail the cellular process modulated during the growth inhibition induced by TSA, we studied the effect of the drug on G(0)/G(1) traverse in mitogen-stimulated quiescent Balb/c-3T3 cells.
