Towards ultrasound-guided adaptive radiotherapy for cervical cancer: Evaluation of Elekta's semiautomated uterine segmentation method on 3D ultrasound images.
(WILEY, 2017-07-01)PURPOSE: 3D ultrasound (US) images of the uterus may be used to adapt radiotherapy (RT) for cervical cancer patients based on changes in daily anatomy. This requires accurate on-line segmentation of the uterus. The aim of ... -
Toxicity and Patient-Reported Outcomes of a Phase 2 Randomized Trial of Prostate and Pelvic Lymph Node Versus Prostate only Radiotherapy in Advanced Localised Prostate Cancer (PIVOTAL).
(ELSEVIER SCIENCE INC, 2019-03-01)PURPOSE: To establish the toxicity profile of high-dose pelvic lymph node intensity-modulated radiation therapy (IMRT) and to assess whether it is safely deliverable at multiple centers. METHODS AND MATERIALS: In this phase ... -
Toxicity, normal tissue and dose-volume planning parameters for radiotherapy in soft tissue sarcoma of the extremities: A systematic review of the literature.
(ELSEVIER IRELAND LTD, 2023-09-01)BACKGROUND: Patients with soft tissue sarcoma of the extremities (STSE) are left with high incidence of toxicities after Radiotherapy (RT). Understanding the normal tissue dose relationship with the development of long-term ... -
TP53 modulates radiotherapy fraction size sensitivity in normal and malignant cells.
(NATURE PORTFOLIO, 2021-03-29)Recent clinical trials in breast and prostate cancer have established that fewer, larger daily doses (fractions) of radiotherapy are safe and effective, but these do not represent personalised dosing on a patient-by-patient ... -
TP53 Mutational Status Is a Potential Marker for Risk Stratification in Wilms Tumour with Diffuse Anaplasia
(2014-10-01)Purpose: The presence of diffuse anaplasia in Wilms tumours (DAWT) is associated with TP53 mutations and poor outcome. As patients receive intensified treatment, we sought to identify whether TP53 mutational status confers ... -
TPOAb and Thyroid Function Are Not Associated with Breast Cancer Outcome: Evidence from a Large-Scale Study Using Data from the Taxotere as Adjuvant Chemotherapy Trial (TACT, CRUK01/001).
(KARGER, 2017-07-01)BACKGROUND: Small-scale studies correlated the presence of thyroid autoimmunity with both improved or worsened breast cancer outcome. OBJECTIVES: We aimed to clarify this association in a large cohort using the phase III, ... -
Traceable reference dosimetry in MRI guided radiotherapy using alanine: calibration and magnetic field correction factors of ionisation chambers.
(IOP PUBLISHING LTD, 2021-08-06)Magnetic resonance imaging (MRI)-guided radiotherapy (RT) (MRIgRT) falls outside the scope of existing high energy photon therapy dosimetry protocols, because those protocols do not consider the effects of the magnetic ... -
Tracheo-oesophageal fistula: a delayed complication of missed inhaled magnetic toys.
(OXFORD UNIV PRESS, 2018-02-01)Delayed diagnosis of tracheobronchial foreign body (FB) aspiration is not uncommon in children. It occurs when symptoms are underappreciated and/or radiological findings are overlooked. In such cases serious complications ... -
Tracking Cancer Evolution Reveals Constrained Routes to Metastases: TRACERx Renal.
(CELL PRESS, 2018-04-19)Clear-cell renal cell carcinoma (ccRCC) exhibits a broad range of metastatic phenotypes that have not been systematically studied to date. Here, we analyzed 575 primary and 335 metastatic biopsies across 100 patients with ... -
Tracking evolution of aromatase inhibitor resistance with circulating tumour DNA analysis in metastatic breast cancer.
(ELSEVIER, 2017-10-04)BACKGROUND: Selection of resistance mutations may play a major role in the development of endocrine resistance. ESR1 mutations are rare in primary breast cancer but have high prevalence in patients treated with aromatase ... -
Tracking the molecular and metabolic fingerprints of inhalational versus intravenous anaesthetics in preclinical models of breast cancer

Tracking tumour evolution through adjuvant therapy in Triple Negative Breast Cancer
(Institute of Cancer Research (University Of London), 2024-05-20)Abstract Relapsed Triple Negative Breast Cancer (TNBC) carries a poor prognosis. Improved understanding of the molecular features of early disease, and the evolution of TNBC from early to relapsed disease, is likely to ... -
TRAFIC: statistical design and analysis plan for a pragmatic early phase 1/2 Bayesian adaptive dose escalation trial in rheumatoid arthritis.
(BMC, 2021-07-06)BACKGROUND: Adaptive model-based dose-finding designs have demonstrated advantages over traditional rule-based designs but have increased statistical complexity but uptake has been slow especially outside of cancer trials. ... -
Training and accreditation standards for pathologists undertaking clinical trial work.
(WILEY, 2019-04-01)Clinical trials rely on multidisciplinary teams for successful delivery. Pathologists should be involved in clinical trial design from the outset to ensure that protocols are optimised to deliver maximum data collection ... -
Trametinib versus standard of care in patients with recurrent low-grade serous ovarian cancer (GOG 281/LOGS): an international, randomised, open-label, multicentre, phase 2/3 trial.
(ELSEVIER SCIENCE INC, 2022-02-05)BACKGROUND: Low-grade serous carcinoma of the ovary or peritoneum is characterised by MAPK pathway aberrations and its reduced sensitivity to chemotherapy relative to high-grade serous carcinoma. We compared the MEK inhibitor ... -
