Spatial analyses of immune cell infiltration in cancer: current methods and future directions: A report of the International Immuno-Oncology Biomarker Working Group on Breast Cancer.
(WILEY, 2023-08-01)Modern histologic imaging platforms coupled with machine learning methods have provided new opportunities to map the spatial distribution of immune cells in the tumor microenvironment. However, there exists no standardized ... -
Spatial interplay of lymphocytes and fibroblasts in estrogen receptor-positive HER2-negative breast cancer.
(NATURE PORTFOLIO, 2022-04-28)In estrogen-receptor-positive, HER2-negative (ER+HER2-) breast cancer, higher levels of tumor infiltrating lymphocytes (TILs) are often associated with a poor prognosis and this phenomenon is still poorly understood. ... -
Spatial interrogation of tumour microenvironment using artificial intelligence
(Institute of Cancer Research (University Of London), 2023-03-06)The tumour microenvironment can provide critical information for disease diagnosis, treatment planning, and prognosis. However, the complexity of its morphological, cellular, and spatial architecture hinders accurate ... -
Spatial localisation of Discoidin Domain Receptor 2 (DDR2) signalling is dependent on its collagen binding and kinase activity.
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2018-06-18)Discoidin Domain Receptor 2 (DDR2) is a collagen-binding receptor tyrosine kinase that initiates delayed and sustained tyrosine phosphorylation signalling. To understand the molecular basis of this unique phosphorylation ... -
Spatial patterns of tumour growth impact clonal diversification in a computational model and the TRACERx Renal study.
(NATURE PORTFOLIO, 2022-01-01)Genetic intra-tumour heterogeneity fuels clonal evolution, but our understanding of clinically relevant clonal dynamics remain limited. We investigated spatial and temporal features of clonal diversification in clear cell ... -
Spatial Phenotyping of Tumour Immune Microenvironment in the Non-small Cell Lung Cancer Using Artificial Intelligence
(Institute of Cancer Research (University Of London), 2024-02-26)Lung cancer is the second most common cancer type worldwide, with a five-year survival rate of about 20%. The aggressiveness of the disease and the inefficiency of treatment are partially attributed to the intra-tumour ... -
Spatially constrained tumour growth affects the patterns of clonal selection and neutral drift in cancer genomic data.
(PUBLIC LIBRARY SCIENCE, 2019-07-29)Quantification of the effect of spatial tumour sampling on the patterns of mutations detected in next-generation sequencing data is largely lacking. Here we use a spatial stochastic cellular automaton model of tumour growth ... -
Spect perfusion imaging versus CT for predicting radiation injury to normal lung in lung cancer patients.
(BRITISH INST RADIOLOGY, 2019-09-01)OBJECTIVES: In non-small cell lung cancer (NSCLC) patients, to establish whether the fractional volumes of irradiated anatomic or perfused lung differed between those with and without deteriorating lung function or radiation ... -
SPIRE - combining SGI-110 with cisplatin and gemcitabine chemotherapy for solid malignancies including bladder cancer: study protocol for a phase Ib/randomised IIa open label clinical trial.
(BIOMED CENTRAL LTD, 2018-04-03)BACKGROUND: Urothelial bladder cancer (UBC) accounts for 10,000 new diagnoses and 5000 deaths annually in the UK (Cancer Research UK, http://www.cancerresearchuk.org/health-professional/cancer-statistics/statistics-by-ca ... -
SPIRIT and CONSORT extensions for early phase dose-finding clinical trials: the DEFINE (DosE-FIndiNg Extensions) study protocol.
(BMJ PUBLISHING GROUP, 2023-03-29)INTRODUCTION: Early phase dose-finding (EPDF) studies are critical for the development of new treatments, directly influencing whether compounds or interventions can be investigated in further trials to confirm their safety ... -
Splenic diffuse red pulp small B-cell lymphoma: revision of a series of cases reveals characteristic clinico-pathological features
(FERRATA STORTI FOUNDATION, 2010-07)Background Splenic diffuse red pulp small B-cell lymphoma is an uncommon B-cell lymphoma, now recognized as a provisional entity in the 2008 update of the WHO Classification. Additional work is required to review this ... -
Splenic volume as a predictor of treatment response in patients with non-small cell lung cancer receiving immunotherapy.
(Public Library of Science (PLoS), 2022-01-01)INTRODUCTION: The spleen is a lymphoid organ and we hypothesize that clinical benefit to immunotherapy may present with an increase in splenic volume during treatment. The purpose of this study was to investigate whether ... -
Splicing dysregulation as a driver of breast cancer.
(BIOSCIENTIFICA LTD, 2018-09-01)Breast cancer is known to be a heterogeneous disease driven by a large repertoire of molecular abnormalities, which contribute to its diverse clinical behaviour. Despite the success of targeted therapy approaches for breast ... -
Splicing imbalances in basal-like breast cancer underpin perturbation of cell surface and oncogenic pathways and are associated with patients' survival.
(NATURE PORTFOLIO, 2017-01-06)Despite advancements in the use of transcriptional information to understand and classify breast cancers, the contribution of splicing to the establishment and progression of these tumours has only recently starting to ... -
