Five-fraction Radiotherapy for Breast Cancer: FAST-Forward to Implementation.
(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 ... -
Focal amplification of the androgen receptor gene in hormone-naive human prostate cancer
(NATURE PUBLISHING GROUP, 2014-03-18)Background: Androgen receptor (AR)-gene amplification, found in 20-30% of castration-resistant prostate cancer (CRPCa) is proposed to develop as a consequence of hormone-deprivation therapy and be a prime cause of treatment ... -
Focused ultrasound transducer spatial peak intensity estimation: a comparison of methods.
(2018-03-07)Characterisation of the spatial peak intensity at the focus of high intensity focused ultrasound transducers is difficult because of the risk of damage to hydrophone sensors at the high focal pressures generated. Hill et ... -

Focused Ultrasound-Mediated Hyperthermia in Vitro: An Experimental Arrangement for Treating Cells under Tissue-Mimicking Conditions.
(ELSEVIER SCIENCE INC, 2019-12-01)An experimental arrangement that allows in vitro exposure of cells to focused ultrasound-mediated hyperthermia (43°C-55°C) in a tissue-mimicking phantom with biological, acoustic and thermal properties comparable to those ... -
Four-dimensional imaging for radiotherapy planning in children and teenagers
(Institute of Cancer Research (University Of London), 2021-02-28)Respiratory-related organ motion (RROM) is a potential source of geometric uncertainty in RT planning and delivery. Approaches to mitigate its effects are well described in adults. For example, four-dimensional computed ... -

Frailty in Very Elderly Patients is Not Associated with Adverse Surgical or Oncological Outcomes in Extremity Surgery for Soft Tissue Sarcoma.
(SPRINGER, 2022-02-03)BACKGROUND: While surgery remains the mainstay of treatment for limb sarcoma, extreme old age is a relative contraindication to oncological surgery. METHODS: Patients >80 years referred with primary extremity soft-tissue ... -
FRMD6 has tumor suppressor functions in prostate cancer.
(SPRINGERNATURE, 2021-01-28)Available tools for prostate cancer (PC) prognosis are suboptimal but may be improved by better knowledge about genes driving tumor aggressiveness. Here, we identified FRMD6 (FERM domain-containing protein 6) as an aberrantly ... -
From 25 Fractions to Five: How Hypofractionation has Revolutionised Adjuvant Breast Radiotherapy.
(ELSEVIER SCIENCE LONDON, 2022-05-01)There is a sound empirical basis for hypofractionation in radiotherapy for breast cancer. This article reviews the radiobiological implications of hypofractionation in breast cancer derived from a series of clinical trials ... -
From Clinical Trials to Real-life Clinical Practice: The Role of Immunotherapy with PD-1/PD-L1 Inhibitors in Advanced Urothelial Carcinoma.
(ELSEVIER, 2018-12-01)CONTEXT: A number of PD-1/PD-L1 inhibitors have recently been approved for use in patients with locally advanced or metastatic urothelial carcinoma (UC) on the basis of results from several clinical trials. OBJECTIVE: To ... -
