Combining BRAF inhibition with oncolytic herpes simplex virus enhances the immune-mediated antitumor therapy of BRAF-mutant thyroid cancer.
(BMJ PUBLISHING GROUP, 2020-01-01)BACKGROUND: The aggressive clinical behavior of poorly differentiated and anaplastic thyroid cancers (PDTC and ATC) has proven challenging to treat, and survival beyond a few months from diagnosis is rare. Although 30%-60% ... -
Combining Molecularly Targeted Agents: Is More Always Better?
(AMER ASSOC CANCER RESEARCH, 2017-03-01)The concurrent targeting of critical nodes along key signaling pathways with molecularly targeted agents is a rational antitumor strategy, which has had varying degrees of success. Combinatorial challenges include overcoming ... -
Combining radiation with hyperthermia: a multiscale model informed by in vitro experiments.
(ROYAL SOC, 2018-01-01)Combined radiotherapy and hyperthermia offer great potential for the successful treatment of radio-resistant tumours through thermo-radiosensitization. Tumour response heterogeneity, due to intrinsic, or micro-environmentally ... -
Common genetic variation associated with increased susceptibility to prostate cancer does not increase risk of radiotherapy toxicity.
(NATURE PUBLISHING GROUP, 2016-05-10)BACKGROUND: Numerous germline single-nucleotide polymorphisms increase susceptibility to prostate cancer, some lying near genes involved in cellular radiation response. This study investigated whether prostate cancer ... -
Comparative Validation of Breast Cancer Risk Prediction Models and Projections for Future Risk Stratification.

Comparing programmed death ligand 1 scores for predicting pembrolizumab efficacy in head and neck cancer.
(ELSEVIER SCIENCE INC, 2020-11-25)Tumor proportion score (TPS) and combined positive score ([CPS] includes immune cells), 2 methods for scoring programmed death ligand 1 (PD-L1) expression, have been used in clinical trials investigating the immune checkpoint ... -
COmparing Urolift and Standard Transurethral resection of prostate Ahead of Radiotherapy in men with urinary symptoms secondary to prostate enlargement in Southwest London and North Cumbria (CO-STAR): a study protocol for a randomised feasibility study.
(BMJ PUBLISHING GROUP, 2023-10-06)INTRODUCTION: Patients undergoing prostate radiotherapy with an enlarged prostate can have short-term and long-term urinary complications. Currently, transurethral resection of the prostate (TURP) is the mainstay surgical ... -
Comparison of 90Y SIRT predicted and delivered absorbed doses using a PSF conversion method.
(ELSEVIER SCI LTD, 2021-07-30)PURPOSE: The aims of this study were to develop and apply a method to correct for the differences in partial volume effects of pre-therapy Technetium-99 m (99mTc)-MAA SPECT and post-therapy Yttrium-90 (90Y) bremsstrahlung ... -
Comparison of Imaging Changes and Pain Responses in Patients with Intra- or Extraosseous Bone Metastases Treated Palliatively with Magnetic Resonance-Guided High-Intensity-Focused Ultrasound.
(ELSEVIER SCIENCE INC, 2019-02-21)PURPOSE: This study compared changes in imaging and in pain relief between patients with intraosseous, as opposed to extraosseous bone metastases. Both groups were treated palliatively with magnetic resonance-guided ... -
Comparison of Immediate versus Delayed DIEP Flap Reconstruction in Women Who Require Postmastectomy Radiotherapy.
(2018-09)Background The authors investigated aesthetic outcome and patient satisfaction in women who have undergone deep inferior epigastric artery perforator (DIEP) flap reconstruction in the setting of postmastectomy radiotherapy. ... -
