Clinical Outcomes of a Randomized Trial of Adaptive Plan-of-the-Day Treatment in Patients Receiving Ultra-hypofractionated Weekly Radiation Therapy for Bladder Cancer.
(ELSEVIER SCIENCE INC, 2021-06-01)PURPOSE: Hypofractionated radiation therapy can be used to treat patients with muscle-invasive bladder cancer unable to have radical therapy. Toxicity is a key concern, but adaptive plan-of the day (POD) image-guided ... -
Features and Management of Late Relapse of Nonseminomatous Germ Cell Tumour.
(ELSEVIER, 2021-06-07)BACKGROUND: Late relapse (LR) of nonseminomatous germ cell tumour (NSGCT) is uncommon, with limited data published. LR is defined as relapse occurring after a disease-free interval of 2 yr. OBJECTIVE: To review features ... -
Tipifarnib in Head and Neck Squamous Cell Carcinoma With HRAS Mutations.
(LIPPINCOTT WILLIAMS & WILKINS, 2021-06-10)PURPOSE: Mutations in the HRAS (mHRAS) proto-oncogene occur in 4%-8% of patients with recurrent and/or metastatic (R/M) head and neck squamous cell carcinoma (HNSCC). Tipifarnib is a farnesyltransferase inhibitor that ... -
The predictive ability of the 313 variant-based polygenic risk score for contralateral breast cancer risk prediction in women of European ancestry with a heterozygous BRCA1 or BRCA2 pathogenic variant.
(ELSEVIER SCIENCE INC, 2021-06-10)PURPOSE: To evaluate the association between a previously published 313 variant-based breast cancer (BC) polygenic risk score (PRS313) and contralateral breast cancer (CBC) risk, in BRCA1 and BRCA2 pathogenic variant ... -
Performance of African-ancestry-specific polygenic hazard score varies according to local ancestry in 8q24.
(SPRINGERNATURE, 2021-06-14)BACKGROUND: We previously developed an African-ancestry-specific polygenic hazard score (PHS46+African) that substantially improved prostate cancer risk stratification in men with African ancestry. The model consists of ... -
APOBEC and Cancer Viroimmunotherapy: Thinking the Unthinkable.
(AMER ASSOC CANCER RESEARCH, 2021-06-15)The apolipoprotein B mRNA editing enzyme catalytic polypeptide (APOBEC) family protects against infection by degrading incoming viral genomes through cytosine deamination. Here, we review how the potential to unleash these ... -
Quantification of Differential Response of Tumour and Normal Cells to Microbeam Radiation in the Absence of FLASH Effects.
(MDPI, 2021-06-29)Microbeam radiotherapy (MRT) is a preclinical method of delivering spatially-fractionated radiotherapy aiming to improve the therapeutic window between normal tissue complication and tumour control. Previously, MRT was ... -
Predictors of toxicity in prostate hypofractionation clinical trials

International Recommendations on Reirradiation by Intensity Modulated Radiation Therapy for Locally Recurrent Nasopharyngeal Carcinoma.
(ELSEVIER SCIENCE INC, 2021-07-01)PURPOSE: Reirradiation for locally recurrent nasopharyngeal carcinoma (NPC) is challenging because prior radiation dose delivered in the first course is often close to the tolerance limit of surrounding normal structures. ... -
Inclusion of a Charge Sharing Correction Algorithm Into an X-Ray Photon Counting Spectral Detector Simulation Framework
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2021-07-01) -
The BARCODE1 Pilot: a feasibility study of using germline single nucleotide polymorphisms to target prostate cancer screening.
(WILEY, 2021-07-02)OBJECTIVES: To assess the feasibility and uptake of a community-based prostate cancer (PCa) screening programme selecting men according to their genetic risk of PCa. To assess the uptake of PCa screening investigations by ... -
Pulsed focused ultrasound can improve the anti-cancer effects of immune checkpoint inhibitors in murine pancreatic cancer.
(ROYAL SOC, 2021-07-07)Pulsed high-intensity focused ultrasound (pHIFU) uses acoustic pressure to physically disrupt tumours. The aim of this study was to investigate whether pHIFU can be used in combination with immune checkpoint inhibitors ... -
Large-scale cross-cancer fine-mapping of the 5p15.33 region reveals multiple independent signals.
(ELSEVIER, 2021-07-08)Genome-wide association studies (GWASs) have identified thousands of cancer risk loci revealing many risk regions shared across multiple cancers. Characterizing the cross-cancer shared genetic basis can increase our ... -
Treatment Outcomes for Small Cell Carcinoma of the Bladder: Results From a UK Patient Retrospective Cohort Study.
(ELSEVIER SCIENCE INC, 2021-07-15)PURPOSE: Small cell carcinoma of the bladder (SCCB) is rare, accounting for less than 1% of all bladder carcinomas. It is aggressive, and outcomes are poor as a result of its early metastatic spread. Owing to its rarity, ... -
Marital status and prostate cancer incidence: a pooled analysis of 12 case-control studies from the PRACTICAL consortium.
(SPRINGER, 2021-07-18)While being in a committed relationship is associated with a better prostate cancer prognosis, little is known about how marital status relates to its incidence. Social support provided by marriage/relationship could promote ... -
