From October 2016 to October 2020 14 patients were treated with VMAT-based SABR (NG: 6/14, 8/14 RG RT including 3/8 DIBH SABR). Treatment verification consisted of 3D/4D CBCTs. For intrafractional tumor visualization (11/14) different type of fiducials were used. The average treatment time was the shortest with NG RT, followed by DIBH and RG RT. However, the best image quality was achieved with DIBH technique. The Krippendorff's agreement test among three independent RTTs showed that DIBH CBCT (Cone Beam CT) can produce sufficient image quality for OARs and can be used to reliably determine OARs position related to safety zone (PRV). Overall, marker-based DIBH SABR with intrafractional tumor visualization appears to be the best technique on linac at present.","PeriodicalId":18175,"journal":{"name":"Magyar onkologia","volume":"65 1","pages":"6-13"},"PeriodicalIF":0.0,"publicationDate":"2021-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25497232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of our study was to compare the radiobiological effects of flattening filter and flattening filter free photon beams on chromosomal aberrations in peripheral blood lymphocytes. In our study the blood of the same healthy donor was irradiated with linear accelerator using both conventional flattening filter (FF) and FFF photon beams at dose rate of 3.57-23.08 Gy/min, using 6 or 10 MV. The dose-response calibration curves for dicentric + ring chromosomes induced by irradiation were fitted with linear-quadratic model. CABAS (Chromosomal Aberration Calculation Software) was used to prepare the curves. The coefficients and equations of the curves were calculated and compared with the results of other authors. We found significant differences in the number of aberrations at different irradiation parameters. Based on our results, FFF mode has a 10-20% higher biological effect than FF mode. These results can be used during radiotherapy or to estimate the biological doses in case of an accidental exposure to radiation.","PeriodicalId":18175,"journal":{"name":"Magyar onkologia","volume":"65 1","pages":"30-37"},"PeriodicalIF":0.0,"publicationDate":"2021-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25487151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A survey was made of SPC among 124 young (≤50 years) patients with squamous cell carcinoma of the head and neck who were enrolled in a pretreatment mutagen sensitivity investigation during 1996-2006. Mutagen sensitivity was assessed by exposing lymphocytes to bleomycin in vitro and quantitating the bleomycin-induced chromatid breaks per cell (b/c). Patients were classified as hypersensitive (>1 b/c) or not hypersensitive (≤1 b/c). The mean follow-up time was 64 months (range: 5-244 months). Eighteen patients (15%) developed a SPC. The 10-year estimated rate of SPC for hypersensitive (n=65) or not hypersensitive (n=59) patients were 17% and 30%, respectively (p=0.4272).

The development of new medical treatment options in cancer care allows longer survival for cancer patients. Because of this, quality of life becomes an increasingly important factor during treatments. Psycho-oncological interventions include all psychosocial interventions that are designed to positively influence the patient's psychosocial adaptation and adjustment to diagnosis, treatment, and survivorship. Interventions also promote rehabilitation progress and help the emotional integration of disease-related crisis and trauma. Psycho-oncological therapies are supposed to manage cancer-related distress and other psychosocial problems by specific types of treatments or interventions. It is crucial for the medical system to deal with the psychosocial aspects of cancer care in order to identify and deal with patients' needs for better compliance and adherence to treatment. The key of personalized holistic rehabilitation is multidisciplinary teamwork during the whole healing process: sharing the emotional experience also helps to prevent healthcare workers' burnout.","PeriodicalId":18175,"journal":{"name":"Magyar onkologia","volume":"65 1","pages":"78-88"},"PeriodicalIF":0.0,"publicationDate":"2021-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25487157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
