Second primary malignancies induced by radioactive iodine treatment of differentiated thyroid carcinoma - a critical review and evaluation of the existing evidence.
(SPRINGER, 2022-03-23)PURPOSE: Concern is growing about long-term side effects of differentiated thyroid cancer treatment, most notably radioactive iodine (RAI) therapy. However, published studies on the subject have had heterogeneous cohorts ... -
Hallmarks of Resistance to Immune-Checkpoint Inhibitors.
(AMER ASSOC CANCER RESEARCH, 2022-04-01)Immune-checkpoint inhibitors (ICI), although revolutionary in improving long-term survival outcomes, are mostly effective in patients with immune-responsive tumors. Most patients with cancer either do not respond to ICIs ... -
Clinical Implementation of Robust Multi-isocentric Volumetric Modulated Arc Radiotherapy for Craniospinal Irradiation.
(ELSEVIER SCIENCE LONDON, 2022-04-01)AIMS: To determine if multi-isocentric volumetric modulated arc radiotherapy for craniospinal irradiation (CSI-VMAT) can be implemented safely and accurately using robust optimisation in a commercially available treatment ... -
Primary radiotherapy and deep inferior epigastric perforator flap reconstruction for patients with breast cancer (PRADA): a multicentre, prospective, non-randomised, feasibility study.
(ELSEVIER SCIENCE INC, 2022-04-07)BACKGROUND: Radiotherapy before mastectomy and autologous free-flap breast reconstruction can avoid adverse radiation effects on healthy donor tissues and delays to adjuvant radiotherapy. However, evidence for this treatment ... -
How can we recruit more men of African or African-Caribbean ancestry into our research? Co-creating a video to raise awareness of prostate cancer risk and the PROFILE study.
(Springer Science and Business Media LLC, 2022-04-18)BACKGROUND: Men of African ancestry are at increased risk of developing prostate cancer (PrCa) compared to men from other backgrounds. The PROFILE study aims to understand whether genetic information can better target who ... -
Prostate Volume Changes during Extreme and Moderately Hypofractionated Magnetic Resonance Image-guided Radiotherapy.
(ELSEVIER SCIENCE LONDON, 2022-04-22)AIMS: Prostate morphological changes during external beam radiotherapy are poorly understood. Excellent soft-tissue visualisation offered by magnetic resonance image-guided radiotherapy (MRIgRT) provides an opportunity to ... -
Habitat Imaging of Tumors Enables High Confidence Sub-Regional Assessment of Response to Therapy.
(MDPI, 2022-04-26)Imaging biomarkers are used in therapy development to identify and quantify therapeutic response. In oncology, use of MRI, PET and other imaging methods can be complicated by spatially complex and heterogeneous tumor ... -
Intravenous Oncolytic Vaccinia Virus Therapy Results in a Differential Immune Response between Cancer Patients.
(MDPI, 2022-04-27)Pexa-Vec is an engineered Wyeth-strain vaccinia oncolytic virus (OV), which has been tested extensively in clinical trials, demonstrating enhanced cytotoxic T cell infiltration into tumours following treatment. Favourable ... -
Monitoring tumour response to extracellular matrix modulation with multiparametric MRI
(Institute of Cancer Research (University Of London), 2022-04-30)Primary breast tumours are characterised by a dense extracellular matrix (ECM), with accumulation of collagen and hyaluronan (HA). This stromal dense phenotype is associated with tumour progression, metastasis and poor ... -
Local control and toxicity after hypofractionated accelerated palliative RT in breast cancer
(ELSEVIER IRELAND LTD, 2022-05-01) -
How Low Can You Go? The Radiobiology of Hypofractionation.
(ELSEVIER SCIENCE LONDON, 2022-05-01)Hypofractionated radical radiotherapy is now an accepted standard of care for tumour sites such as prostate and breast cancer. Much research effort is being directed towards more profoundly hypofractionated (ultrahypofractionated) ... -
Addition of nintedanib or placebo to neoadjuvant gemcitabine and cisplatin in locally advanced muscle-invasive bladder cancer (NEOBLADE): a double-blind, randomised, phase 2 trial.
(ELSEVIER SCIENCE INC, 2022-05-01)BACKGROUND: Recurrence is common after neoadjuvant chemotherapy and radical treatment for muscle-invasive bladder cancer. We investigated the effect of adding nintedanib to neoadjuvant chemotherapy on response and survival ... -
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 ... -
A Rare Germline HOXB13 Variant Contributes to Risk of Prostate Cancer in Men of African Ancestry.
(ELSEVIER, 2022-05-01)A rare African ancestry-specific germline deletion variant in HOXB13 (X285K, rs77179853) was recently reported in Martinican men with early-onset prostate cancer. Given the role of HOXB13 germline variation in prostate ... -
