DOSE-ESCALATED EXTERNAL BEAM RADIOTHERAPY DURING HORMONO-RADIOTHERAPY FOR PROSTATE CANCER

Сибирский онкологический журнал, 2016
Introduction. The introduction of modern technologies of conformal external beam radiotherapy (EBRT) into clinical practice for the treatment of prostate cancer requires proper quality assurance measures as well as a careful analysis of both the efficacy

External beam radiation dose escalation for high grade glioma

Cochrane Database of Systematic Reviews, 2015
This is an updated version of the original Cochrane Review published in Issue 8, 2016. High grade glioma (HGG) is a rapidly growing brain tumour in the supporting cells of the nervous system, with several subtypes such as glioblastoma (grade IV astrocytoma), anaplastic (grade III) astrocytoma and anaplastic (grade III) oligodendroglioma.

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

Molecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

ON THE RELATIONSHIP BETWEEN AMBIENT DOSE EQUIVALENT AND ABSORBED DOSE IN AIR IN THE CASE OF LARGE-SCALE CONTAMINATION OF THE ENVIRONMENT BY RADIOACTIVE CESIUM

Радиационная гигиена, 2015
One of the main aims of the study was an experimental determination of the conversion coefficient from ambient dose equivalent rate, Н*(10), to absorbed dose rate in air, D, in the case of radioactive contamination of the environment following the ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Development and operation of a pixel segmented liquid-filled linear array for radiotherapy quality assurance

, 2004
A liquid isooctane (C$_{8}$H$_{18}$) filled ionization linear array for radiotherapy quality assurance has been designed, built and tested. The detector consists of 128 pixels, each of them with an area of 1.7 mm $\times$ 1.7 mm and a gap of 0.5 mm.

Characterizing canine dose from external beam irradiation

, 2011
Absorbed dose from Computed Tomography (CT) is a major concern on an individual basis as well as for the collective population due to increased frequency of and dependency on CT scans for diagnostic and therapeutic imaging. Colorado State University recently integrated a large bore multi-slice Positron Emission Tomography and Computed Tomography (PET ...

Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

Molecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

Evaluation of target dose based on water-equivalent thickness in external beam radiotherapy

Journal of Medical Physics, 2013
In vivo dosimetry was carried out for 152 patients receiving external beam radiotherapy and the treatment sites were divided into two main groups: Thorax, Abdomen, and Pelvic (120 fields) and Head and Neck (52 fields).
