Complete pathologic response to short-course neoadjuvant alectinib in mediastinal node positive (N2) ALK rearranged lung cancer.

Objectives: Neoadjuvant therapy prior to surgical resection for locally advanced lung cancer has evolved to incorporate systemic cytotoxic chemotherapy +/- immunotherapy +/- radiotherapy. The role of neoadjuvant precision therapies remains understudied.

Materials And Methods: We report cases with major and complete pathologic responses to off-label neoadjuvant alectinib.

Tumor Treating Fields for Ovarian Carcinoma: A Modeling Study.

Purpose: Since the inception of tumor treating fields (TTFields) therapy as a Food and Drug Administration-approved treatment with known clinical efficacy against recurrent and newly diagnosed glioblastoma, various in silico modeling studies have been performed in an effort to better understand the distribution of applied electric fields throughout the human body for various malignancies or metastases.

Methods And Materials: Postacquisition attenuation-corrected positron emission tomography-computed tomography image data sets from 2 patients with ovarian carcinoma were used to fully segment various intrapelvic and intra-abdominal gross anatomic structures. A 3-dimensional finite element mesh model was generated and then solved for the distribution of applied electric fields, rate of energy deposition, and current density at the clinical target volumes (CTVs) and other intrapelvic and intra-abdominal structures.

Association of Performance Status With Survival in Patients With Advanced Non-Small Cell Lung Cancer Treated With Pembrolizumab Monotherapy.

Importance: Despite approximately 40% of patients having Eastern Cooperative Oncology Group (ECOG) performance status (PS) scores of at least 2 in the real world, most landmark clinical trials that led to the use of pembrolizumab as standard of care in advanced non-small cell lung cancer (NSCLC) excluded this group.

Objective: To evaluate whether an ECOG PS score of at least 2 at the start of therapy is associated with progression-free survival (PFS) and overall survival (OS) in advanced NSCLC treated with pembrolizumab monotherapy.

Design, Setting, And Participants: This cohort study included all consecutive patients with advanced NSCLC who underwent treatment with palliative pembrolizumab monotherapy from February 2016 to October 2019 at a single academic cancer center, with data censoring on January 15, 2020.

Leukocytosis and Leukemia.

Leukocytosis is among the most common findings on peripheral blood smear. A wide range of causes may mediate this finding, and careful clinical and laboratory evaluation assist in differentiating between benign and malignant causes of increased white blood cell counts. In this article, various nonmalignant causes are explored, including infectious, inflammatory, autoimmune, and allergic.

Not all analogies are created equal: Associative and categorical analogy processing following brain damage.

Current research on analogy processing assumes that different conceptual relations are treated similarly. However, just as words and concepts are related in distinct ways, different kinds of analogies may employ distinct types of relationships. An important distinction in how words are related is the difference between associative (dog-bone) and categorical (dog-cat) relations.

Language, perception, and the schematic representation of spatial relations.

Schemas are abstract nonverbal representations that parsimoniously depict spatial relations. Despite their ubiquitous use in maps and diagrams, little is known about their neural instantiation. We sought to determine the extent to which schematic representations are neurally distinguished from language on the one hand, and from rich perceptual representations on the other.

The right hemisphere in esthetic perception.

Little about the neuropsychology of art perception and evaluation is known. Most neuropsychological approaches to art have focused on art production and have been anecdotal and qualitative. The field is in desperate need of quantitative methods if it is to advance.

The neural basis for spatial relations.

Studies in semantics traditionally focus on knowledge of objects. By contrast, less is known about how objects relate to each other. In an fMRI study, we tested the hypothesis that the neural processing of categorical spatial relations between objects is distinct from the processing of the identity of objects.

Functional-anatomical organization of predicate metaphor processing.

The bulk of the research on the neural organization of metaphor comprehension has focused on nominal metaphors and the metaphoric relationships between word pairs. By contrast, little work has been conducted on predicate metaphors using verbs of motion such as "The man fell under her spell." We examined predicate metaphors as compared to literal sentences of motion such as "The child fell under the slide" in an event-related, functional MRI study.

Take it to the bridge: an interhemispheric processing advantage for emotional faces.

Recent evidence indicates that emotional stimuli may be accorded special priority in information processing. Extending that research, this study tested the hypothesis that communication between the left and right hemispheres would be facilitated for emotional compared to non-emotional faces. Sixty-eight participants matched angry, happy, and neutral face photographs either within a single visual field (i.
