Pineoblastoma segregates into molecular sub-groups with distinct clinico-pathologic features: a Rare Brain Tumor Consortium registry study.
(SPRINGER, 2020-02-01)Pineoblastomas (PBs) are rare, aggressive pediatric brain tumors of the pineal gland with modest overall survival despite intensive therapy. We sought to define the clinical and molecular spectra of PB to inform new treatment ... -
Pitfalls in assessing stromal tumor infiltrating lymphocytes (sTILs) in breast cancer.
(NATURE RESEARCH, 2020-05-12)Stromal tumor-infiltrating lymphocytes (sTILs) are important prognostic and predictive biomarkers in triple-negative (TNBC) and HER2-positive breast cancer. Incorporating sTILs into clinical practice necessitates reproducible ... -
PIVOT-10: Phase II study of bempegaldesleukin plus nivolumab in cisplatin-ineligible advanced urothelial cancer.
(FUTURE MEDICINE LTD, 2020-09-16)The choice of first-line therapy for patients with metastatic urothelial cancer (mUC) is based on cisplatin-eligibility and programmed death-ligand 1 (PD-L1) status. For patients with mUC who are ineligible for cisplatin ... -
PIVOTALboost: A phase III randomised controlled trial of prostate and pelvis versus prostate alone radiotherapy with or without prostate boost (CRUK/16/018).
(ELSEVIER IRELAND LTD, 2020-11-01)•PIVOTALboost evaluates benefits/toxicity of pelvic node RT and focal boost dose escalation.•Unfavourable intermediate/high risk and bulky local disease are most likely to benefit.•Functional MRI imaging is used to select ... -
PKA-regulated VASP phosphorylation promotes extrusion of transformed cells from the epithelium.
(COMPANY OF BIOLOGISTS LTD, 2014-08-15)At the early stages of carcinogenesis, transformation occurs in single cells within tissues. In an epithelial monolayer, such mutated cells are recognized by their normal neighbors and are often apically extruded. The ... -
Plane wave versus focused transmissions for contrast enhanced ultrasound imaging: the role of parameter settings and the effects of flow rate on contrast measurements.
(IOP PUBLISHING LTD, 2019-04-23)Contrast enhanced ultrasound (CEUS) and dynamic contrast enhanced ultrasound (DCE-US) can be used to provide information about the vasculature aiding diagnosis and monitoring of a number of pathologies including cancer. ... -
Plasma Cell-free DNA Concentration and Outcomes from Taxane Therapy in Metastatic Castration-resistant Prostate Cancer from Two Phase III Trials (FIRSTANA and PROSELICA).
(ELSEVIER, 2018-09-01)BACKGROUND: Noninvasive biomarkers are needed to guide metastatic castration-resistant prostate cancer (mCRPC) treatment. OBJECTIVE: To clinically qualify baseline and on-treatment cell-free DNA (cfDNA) concentrations as ... -
Plasma ESR1 Mutations and the Treatment of Estrogen Receptor-Positive Advanced Breast Cancer.
(2016-09)Purpose ESR1 mutations are selected by prior aromatase inhibitor (AI) therapy in advanced breast cancer. We assessed the impact of ESR1 mutations on sensitivity to standard therapies in two phase III randomized trials that ... -
Plasma Metabolomic Changes following PI3K Inhibition as Pharmacodynamic Biomarkers: Preclinical Discovery to Phase I Trial Evaluation.
(AMER ASSOC CANCER RESEARCH, 2016-06-01)PI3K plays a key role in cellular metabolism and cancer. Using a mass spectrometry-based metabolomics platform, we discovered that plasma concentrations of 26 metabolites, including amino acids, acylcarnitines, and ... -
Plasma Tie2 is a tumor vascular response biomarker for VEGF inhibitors in metastatic colorectal cancer.
(NATURE PUBLISHING GROUP, 2018-11-07)Oncological use of anti-angiogenic VEGF inhibitors has been limited by the lack of informative biomarkers. Previously we reported circulating Tie2 as a vascular response biomarker for bevacizumab-treated ovarian cancer ... -
Plasmacytoid dendritic cells orchestrate innate and adaptive anti-tumor immunity induced by oncolytic coxsackievirus A21.
(BMJ PUBLISHING GROUP, 2019-07-01)BACKGROUND: The oncolytic virus, coxsackievirus A21 (CVA21), has shown promise as a single agent in several clinical trials and is now being tested in combination with immune checkpoint blockade. Combination therapies offer ... -
Platinum-Fluoropyrimidine and Paclitaxel-Based Chemotherapy in the Treatment of Advanced Anal Cancer Patients.
(2017-04)Background Although treatment of localized anal cancer (AC) is well established, very little evidence is available to inform the management of advanced tumors, and the prognosis of these patients remains poor. We have ... -
Pleiotropic Analysis of Lung Cancer and Blood Triglycerides.
(OXFORD UNIV PRESS INC, 2016-12-01)Epidemiologically related traits may share genetic risk factors, and pleiotropic analysis could identify individual loci associated with these traits. Because of their shared epidemiological associations, we conducted ... -
PLK1 Activation in Late G2 Sets Up Commitment to Mitosis.
(CELL PRESS, 2017-06-06)Commitment to mitosis must be tightly coordinated with DNA replication to preserve genome integrity. While we have previously established that the timely activation of CyclinB1-Cdk1 in late G2 triggers mitotic entry, the ... -
