Physical symptom burden in patients with desmoid-type fibromatosis and its impact on health-related quality of life and healthcare use.
(WILEY, 2023-06-01)BACKGROUND: Desmoid-type fibromatosis (DTF) has a highly variable clinical course with varying intensity of symptoms. The objectives of this study were to identify subgroups of DTF patients based on physical symptom burden ... -
Physicians, paraproteins and progress: diagnosis and management of myeloma.
(MA HEALTHCARE LTD, 2019-02-02)Myeloma outcomes have improved dramatically over the last decade as a result of novel therapies, several of which are now commonly continued to disease relapse. Physicians who do not work in haematology are therefore more ... -
PIK3CA mutation enrichment and quantitation from blood and tissue.
(NATURE PORTFOLIO, 2020-10-13)PIK3CA is one of the two most frequently mutated genes in breast cancers, occurring in 30-40% of cases. Four frequent 'hotspot' PIK3CA mutations (E542K, E545K, H1047R and H1047L) account for 80-90% of all PIK3CA mutations ... -
PIM1 kinase regulates cell death, tumor growth and chemotherapy response in triple-negative breast cancer.
(NATURE PUBLISHING GROUP, 2016-11-01)Triple-negative breast cancers (TNBCs) have poor prognosis and lack targeted therapies. Here we identified increased copy number and expression of the PIM1 proto-oncogene in genomic data sets of patients with TNBC. TNBC ... -
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 ... -

(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 ... -
