Background and Objectives: Reducing time of treatment during COVID-19 outbreaks has been recommended by the leading Radiation Oncology societies. Still minimizing radiation induced tissue toxicity is one most important issues in breast cancer patients. The study aimed to investigate compliance, clinical dosimetry normal toxicity, cosmetic results between moderated ultra-fractionated regimes for patients pandemic. Materials Methods: This pilot prospective randomized included 60 with early...

Abstract Radiation dermatitis is one of the commonest side effects ionizing radiation which applied in radiotherapy carcinoma all localizations, most frequently tumors breast, head and neck region, lungs soft tissue sarcomas. It usually occurs as a complication breast thus it more often recorded female patients on skin region subjected to radiation. Clinical manifestations can be divided into four phases: acute phase (erythema, dry desquamation, moist ulceration necrosis with resulting...

Introduction. Miopericarditis with clinical presentation of chest pain, electrocardiographic changes and positive cardio specific enzymes is often a differential diagnostic dilemma in relation to acute myocardial infarction. Literature data are very scarce only case reports or small series patients can be found the literature so each significant contribution this issue. Case report. A 19-year-old patient was admitted intensive care unit, signs suspected lesion highly enzymes. Since...

Purpose: There is a paucity of data on physiological heart adaptation in elite-level judo female athletes. This study aimed to assess left ventricular morphology and function highly trained elite judokas. Methods: The prospectively included 18 females aged 23.5 ± 2.25 years, nine level judokas, healthy non-athlete volunteers. All participants underwent medical examination, electrocardiogram, transthoracic 2D echocardiogram. Left diastolic systolic diameters volumes were determined,...

Background and Objectives: Advanced lung cancer is usually manifested by endoluminal tumor propagation, resulting in central airway obstruction. The objective of this study to compare the high dose rate brachytherapy treatment outcomes non-small-cell (NSCLC) depending on planning pattern—two-dimension (2D) or three-dimension (3D) planning. Materials Methods: was retrospective two groups patients were compared it (a group 101 who underwent 2D planned high-dose-rate endobronchial (HDR-EBBT)...

With one third of patients with locally advanced cervical cancer (LACC) expected to develop recurrence in the first two years after therapy, accurate assessment response and timely detection concurrent chemo- radiotherapy (CCRT) treatment is great importance. Although there neither definite consensus about preferred imaging modality, nor time interval until diagnostic examination CCRT, National Comprehensive Cancer Network (NCCN) recommends use MRI 18F-FDG PET/CT as a post-treatment LACC...

Colorectal cancer is one of the most common malignant diseases worldwide. A multidisciplinary approach to treatment involves surgery and chemotherapy, while radiotherapy used in tumors localized pelvis. Stereotactic allows delivery high, ablative radical doses target volumes, with a reduced risk surrounding organs, making it suitable for irradiating disease. 59-year-old female S.M. presented doctor due appearance perianal fistula.

Introduction/Objective. The incidence of radiation-induced side effects in patients with head and neck (H&N) cancer depends on the planning technique irradiation dose, as well primary tumor location within H&N region. aim our research is to establish treated conformal radiotherapy computed tomography (CT) or fusion magnetic resonance imaging (CT-MRI fusion). Methods. Prospective analysis was performed 40 oropharynx carcinoma larynx prospectively followed after radiotherapy. Forty...
