Can patient-reported outcomes be used instead of clinician-reported outcomes and photographs as primary endpoints of late normal tissue effects in breast radiotherapy trials? Results from the IMPORT LOW trial.
Bhattacharya, IS; Haviland, JS; Hopwood, P; Coles, CE; Yarnold, JR; et al. (ELSEVIER IRELAND LTD, 2019-05)BACKGROUND: In an era of low local relapse rates after adjuvant breast radiotherapy, risks of late normal-tissue effects (NTE) need to be balanced against risk of relapse. NTE are assessed using patient-reported outcome ... -

Do Patient-reported Outcome Measures Agree with Clinical and Photographic Assessments of Normal Tissue Effects after Breast Radiotherapy? The Experience of the Standardisation of Breast Radiotherapy (START) Trials in Early Breast Cancer.
Haviland, JS; Hopwood, P; Mills, J; Sydenham, M; Bliss, JM; et al. (ELSEVIER SCIENCE LONDON, 2016-06-01)AIMS: In radiotherapy trials, normal tissue effects (NTE) are important end points and it is pertinent to ask whether patient-reported outcome measures (PROMs) could replace clinical and/or photographic assessments. Data ... -

Haviland, J; Bliss, J; Sydenham, M; Cruickshank, C; Yarnold, J (ELSEVIER SCIENCE INC, 2003-06-01) -
FFPE breast tumour blocks provide reliable sources of both germline and malignant DNA for investigation of genetic determinants of individual tumour responses to treatment.
Wilkins, A; Chauhan, R; Rust, A; Pearson, A; Daley, F; et al. (SPRINGER, 2018-08-01)BACKGROUND: Bio-banked formalin-fixed paraffin-embedded (FFPE) tissues provide an excellent opportunity for translational genomic research. Historically matched blood has not always been collected as a source of germline ... -
Five-fraction Radiotherapy for Breast Cancer: FAST-Forward to Implementation.
Brunt, AM; Haviland, JS; Kirby, AM; Somaiah, N; Wheatley, DA; et al. (ELSEVIER SCIENCE LONDON, 2023-05-19)INTRODUCTION: The phase 3 FAST-Forward trial reported outcomes for 26 and 27 Gy schedules delivered in 5 fractions over 1 week versus 40 Gy in 15 fractions over 3 weeks in 4000 patients. We discuss concerns raised by the ... -
Hyperbaric oxygen for patients with chronic bowel dysfunction after pelvic radiotherapy (HOT2): a randomised, double-blind, sham-controlled phase 3 trial.
Glover, M; Smerdon, GR; Andreyev, HJ; Benton, BE; Bothma, P; et al. (ELSEVIER SCIENCE INC, 2016-02-01)BACKGROUND: Hyperbaric oxygen has been used as a therapy for patients experiencing chronic intestinal syndromes after pelvic radiotherapy for decades, yet the evidence to support the use of this therapy is based almost ... -
Hypofractionated breast radiotherapy for 1 week versus 3 weeks (FAST-Forward): 5-year efficacy and late normal tissue effects results from a multicentre, non-inferiority, randomised, phase 3 trial.
Murray Brunt, A; Haviland, JS; Wheatley, DA; Sydenham, MA; Alhasso, A; et al. (ELSEVIER SCIENCE INC, 2020-05-23)BACKGROUND: We aimed to identify a five-fraction schedule of adjuvant radiotherapy (radiation therapy) delivered in 1 week that is non-inferior in terms of local cancer control and is as safe as an international standard ... -
Increasing the dose intensity of chemotherapy by more frequent administration or sequential scheduling: a patient-level meta-analysis of 37 298 women with early breast cancer in 26 randomised trials.
Early Breast Cancer Trialists' Collaborative Group (EBCTCG), (ELSEVIER SCIENCE INC, 2019-04-06)BACKGROUND: Increasing the dose intensity of cytotoxic therapy by shortening the intervals between cycles, or by giving individual drugs sequentially at full dose rather than in lower-dose concurrent treatment schedules, ... -
Individual patient data meta-analysis shows a significant association between the ATM rs1801516 SNP and toxicity after radiotherapy in 5456 breast and prostate cancer patients.
Andreassen, CN; Rosenstein, BS; Kerns, SL; Ostrer, H; De Ruysscher, D; et al. (ELSEVIER IRELAND LTD, 2016-12-01)PURPOSE: Several small studies have indicated that the ATM rs1801516 SNP is associated with risk of normal tissue toxicity after radiotherapy. However, the findings have not been consistent. In order to test this SNP in a ... -
