Eating disorders, characterized by severe disturbances in eating behavior, are a public health concern, particularly among young women. This longitudinal study aimed to investigate the relationship between disordered eating attitudes and mental health outcomes, including depression, anxiety, and somatization, among individuals with eating disorders. A total of 471 young German women hospitalized with anorexia nervosa or bulimia nervosa participated in this study.

The poor prognosis of patients with esophageal cancer leads to the constant search for new ways of treatment of this disease. One of the methods used in high-grade dysplasia, superficial invasive carcinoma, and sometimes palliative care is photodynamic therapy (PDT). This method has come a long way from the first experimental studies to registration in the treatment of esophageal cancer and is constantly being improved and refined.

Recent comparison of an ultra-hypofractionated radiotherapy (UF-RT) boost to a conventionally fractionated (CF-RT) option showed similar toxicity and disease control outcomes. An analysis of the treatment plans for these patients is needed for evaluating calculated doses for different organs, treatment beam-on time, and requirements for human and financial resources. Eighty-six plans for UF-RT and 93 plans for CF-RT schemes were evaluated.

Introduction: Numerous studies have demonstrated the clinical benefits of using continuous glucose monitoring (CGM) systems among patients with type 1 diabetes (T1D). Aim of the study was to assess the effectiveness of CGM on metabolic control in children with T1D and well-controlled disease prior to the study.

Material And Methods: This prospective analysis included 99 children (46 girls) at the median age of 11.

Purpose: Restricted studies comparing different dose rate parameters are available while ITV-based VMAT lung SBRT planning leads to perform the analysis of the most suitable parameters of the external beams used. The special emphasis was placed on the impact of dose rate on dose distribution variations in target volumes due to interplay effects.

Methods: Four VMAT plans were calculated for 15 lung tumours using 6 MV photon beam quality (flattening filter FF vs.

Aim: To present a proposed gastric cancer intensity-modulated radiotherapy (IMRT) treatment planning protocol for an institution that have not introduced volumetric modulated arc therapy in clinical practice. A secondary aim was to determine the impact of 2DkV set-up corrections on target coverage and organ at risk (OAR).

Methods And Materials: Twenty consecutive patients were treated with a specially-designed non-coplanar 7-field IMRT technique.

Aim: The main purpose of this work is to give a technical description and present the properties of the liver SBRT protocol implemented in the Greater Poland Cancer Centre (GPCC) in Poznan, Poland.

Background: Stereotactic body radiation therapy (SBRT) for liver metastasis is a non-invasive therapeutic option which enables irradiation of a small target in the body with a high dose.

Materials And Methods: This study presents details of our linac-based liver SBRT protocol.

The aim of reporting this case of choroid melanoma of the left eye is to introduce the in-house-designed treatment planning protocol for fractionated radiosurgical ablation of an intraocular lesion. This is a clinical case with emphasis on treatment preparation and delivery using the Accuray CyberKnife Robotic Radiosurgery System (Accuray, Sunnyvale, CA, USA) for a patient immobilized with a head mask and our in-house-made eye fixation system.

Introduction: To establish the optimal planning risk volume (PRV) of the lenses for patients who are receiving radiotherapy to the nasal cavity and paranasal sinus (NCPSC).

Methods: Geometrical uncertainties of the lenses were evaluated for a prospective group of patients (G1). Differences between planned and delivered maximum doses to the lenses were evaluated for every fraction.

Background: Stereotactic body radiation therapy (SBRT) is reported as a well-tolerated treatment modality, which offers a long-term tumor control.

Aims: The aim of the following study is to present the place of proposed treatment preparation and its delivery for liver metastases with conventional linear accelerator among reported SBRT protocols.

Materials And Methods: We present our treatment preparation, planning and set-up verification procedure performed for liver metastasis.

Introduction: To evaluate the impact interfraction prostate (CTV1) motion corrections on doses delivered to seminal vesicles (CTV2) and lymph nodes (CTV3), and to determine ideal planning target volume (PTV) margins for these targets with prostate-based position verification.

Material And Methods: Retrospective analysis based on 253 cone beam computed tomography (CBCT) studies of 28 patients. The isocenter-shift method was used to estimate the interfraction prostate and bony shift effects on the original plan coverage.

Background And Purpose: High dose rate (HDR) brachytherapy is a clinically used procedure in prostate cancer treatment. The purpose of this study was to present the influence of using different optimization algorithms in 3D-CBRT planning on the treatment plan quality.

Materials And Methods: Treatment plans were calculated for 15 patients--three plans for each patient using: geometrical optimization (GO), inverse optimization (IO) and blind inverse optimization (BIO).

Background: Radiotherapy treatment requires delivering high homogenous dose to target volume while sparing organs at risk. That is why accurate patient positioning is one of the most important steps during the treatment process. It reduces set-up errors which have a strong influence on the doses given to the target and surrounding tissues.
