Set-up error validation with EPID images: Measurements vs Egs_cbct simulation
ConclusionIn this study it is demonstrated that a head and neck setup can be verified using substantially fewer projection images. Bony landmarks and air cavities could still be observed in the reconstructed Rando head phantom. The egs_cbct code can be used as a tool to investigate setup errors without tedious measurements with an EPID system. (Source: Reports of Practical Oncology and Radiotherapy)

Measurement of percentage dose at the surface for a 6 MV photon beam
ConclusionsThe RF-EBT3 seems to be a detector suitable for measurements of the dose at the surface. This suggests that RF-EBT3 films might be good candidates as detectors for in vivo dosimetry. (Source: Reports of Practical Oncology and Radiotherapy)

Skin barrier function in patients under radiation therapy due to the head and neck cancers - Preliminary study
ConclusionsThe study showed that radiotherapy causes skin barrier dysfunction in all patients independently of clinical radiodermatitis. The biophysical features of this dysfunction can precede clinical symptoms and they can be assessed by non-invasive and objective methods. (Source: Reports of Practical Oncology and Radiotherapy)

Comparison of patient-specific intensity modulated radiation therapy quality assurance for the prostate across multiple institutions
ConclusionThis survey was an informative trial to understand the verification status of patient-specific IMRT QA measurements for prostate cancer. In most institutions, the point dose measurement and dose distribution differences met the desired criteria. (Source: Reports of Practical Oncology and Radiotherapy)

Changes in lung volume parameters regarding the received dose in the lobes of the lungs after locoregional radiotherapy of breast cancer
ConclusionsThe results of this study showed that lung volume changes were not a cause for concern in breast cancer patients. There are three reasons to support this conclusion. Lung volume changes and percentage reductions in LVP for each Gy increase of MLD and each percentage increase of V20 in each lobe were small; patients were asymptomatic during the follow-up period; and LVP showed partial improvements after 6 months.

Human Papillomavirus and the use of nanoparticles for immunotherapy in HPV-related cancer: A review
Publication date: November–December 2019Source: Reports of Practical Oncology & Radiotherapy, Volume 24, Issue 6Author(s): Michael Jakob Rupar, Pawel Golusinski, Wojciech Golusinski, Michal M. MasternakAbstractHuman Papillomavirus (HPV) remains one of the most commonly contracted sexually transmitted diseases around the world. There are a multitude of HPV types, some of which may never present any symptoms. Others, however, are considered high-risk types, which increase the chance of the person infected to develop cancer. In recent years, the utilization of nanotechnology has allowed researchers to employ and explore the...

Evaluation of plan quality improvements in PlanIQ-guided Autoplanning
ConclusionThe results indicate that, although Autoplan helps achieve the user-defined goals without much manual intervention, the plan quality (OAR sparing) can be significantly improved without taking many iterative steps when PlanIQ suggested clinical goals are used in the Autoplan-based optimization.Advances in knowledgeAt present, there are no published material available about the efficacy of the integration of PlanIQ with Autoplanning®. In the present work, our objective is to evaluate the improvements in plan quality resulting from this integration. (Source: Reports of Practical Oncology and Radiotherapy)

Multiparametric magnetic resonance imaging-guided salvage radiotherapy in prostate cancer
ConclusionSRT to the macroscopic recurrence identified by mpMRI is a feasible and well-tolerated option. In this study, there were no differences in bRFS between MRI-positive and MRI-negative patients, indicating effective targeting of MRI-positive lesions.

The incidence of inflammation among patients suffering from cervix cancer with positive beta haemolytic streptococci cultures from genital tract
ConclusionsPositive cultures of BHS from the genital tract were demonstrated to occur in patients with cervix cancer. Complications were found during radiotherapy in 30 (27%) of these patients, including 20 (18%) patients suffering from clinical symptoms of inflammation. When beta-lactam antibiotics are not recommended because of allergy, sensitivity tests to other drugs are necessary. (Source: Reports of Practical Oncology and Radiotherapy)

Two attempts of surgical treatment were taken three months before radiotherapy. Excessive bleeding did not allow to remove the tumour or to take samples for histopathological examination. Diagnosis was put on the basis of radiological assess...
