Do clinicians and patients agree regarding symptoms? A comparison after definitive radiochemotherapy in 223 uterine cervical cancer patients.

BACKGROUND: In clinical cancer research of morbidity, low associations between clinician-assessed toxicity/morbidity and patient-reported symptoms are consistently described in the literature. While morbidity grading systems are supposed to follow more or less objective criteria, patient reported symptoms inherently are based on a subjective self-evaluation of the impact on quality of life. The aim of this study was to focus on major discrepancies with high clinical relevance and to evaluate its impact with regard to underreporting of morbidity. MATERIAL AND METHODS: Early morbidity assessed by clinicians with CTCAEv.3 and patient reported quality of life (EORTC-QLQ-C30/CX24) were compared regarding 12 overlapping symptoms in 223 patients with uterine cervical cancer 3 months after definitive radio(chemo)therapy in the ongoing EMBRACE study. Mismatches showing discrepancies between both grading systems were classified, if patients reported substantial symptoms (quite a bit/very much) and CTCAE grading was rated G0. RESULTS: In total, 360 substantial symptoms were reported by patients by EORTC-QLQ; 159 (44%) of those were not recognized by CTCAE. Symptoms with the highest occurrence of mismatches overall are urinary frequency, fatigue, and insomnia. Large institutional differences were found, showing two centers with 4 vs. 71% of patients with at least one mismatch. CONCLUSION: Analysis of mismatches indicated a high risk of underestimation of early morbidity. Thus, nearly half of the patient-reported substantial symptoms were not recognized by CTCAE scoring (G0) 3 months after treatment. Prospective assessment of morbidity in clinical studies should, therefore, integrate patient reported symptoms to receive a complete and comprehensive picture.

Is It Possible to Treat Infertility with Stem Cells?

Infertility is a major health problem, and despite improved treatments over the years, there are still some conditions that cannot be treated successfully using a conventional approach. Therefore, new options are being considered and one of them is cell therapy using stem cells. Stem cell treatments for infertility can be divided into two major groups, the first one being direct transplantation of stem cells or their paracrine factors into reproductive organs and the second one being in vitro differentiation into germ cells or gametes. In animal models, all of these approaches were able to improve the reproductive potential of tested animals, although in humans there is still too little evidence to suggest successful use. The reasons for lack of evidence are unavailability of proper material, the complexity of explored biological processes, and ethical considerations. Despite all of the above-mentioned hurdles, researchers were able to show that in women, it seems to be possible to improve some conditions, but in men, no similar clinically important improvement was achieved. To conclude, the data presented in this review suggest that the treatment of infertility with stem cells seems plausible, because some types of treatments have already been tested in humans, achieving live births, while others show great potential only in animal studies, for now.

Impact of transitioning to an online course - A report from the ESTRO gyn teaching course.

INTRODUCTION: In 2020, the ESTRO course on image-guided radiotherapy and chemotherapy in gynaecological cancer was converted into an online version due to the COVID-19 pandemic. This paper describes the change process and evaluates the impact on participants compared with previous live courses. METHODS AND MATERIALS: The 2019 live course contained 41 h of educational content, comprising 33 h of synchronous activities (lectures, interactive activities, videos) and 8 h of homework (contouring, dose planning). For the online course, the lectures were provided as pre-course material (11 mandatory, 22 optional). Contouring/dose planning homework was unchanged. The synchronous sessions were reconfigured as six 2-hour webinars (total educational content ~38 h).Participant numbers/characteristics, engagement and satisfaction for six live courses and the online course were compared. RESULTS: Participant numbers for the online and live courses were similar (90 vs. mean 96). There were more participants from outside Europe (28% vs. mean 18%) and more non-doctors (47% vs. mean 33%). Proportion of participants responding to the pre-course questionnaire was similar (77% vs. mean 78%) but post-course questionnaire response was lower (62% vs. mean 92%).43% participants viewed ≥75% of mandatory lectures before the webinars. 86% viewed the optional lectures. Submissions of contouring and dose planning homework was higher (contouring 77%-90% vs. 56%-69%, dose planning 74%-89% vs. 29%-57%).96% (47/49) participants rated the online course as Excellent (43%) or Good (53%). Overall satisfaction was similar (4.4 vs. mean 4.6). CONCLUSION: Participant satisfaction and engagement with the online course remained high despite less contact time with faculty.

Anal cancer chemoirradiation with curative intent - a single institution experience.

UNLABELLED: Results of radiochemotherapy in 50 patients with squamous cell carcinoma of the anal canal, treated with radical radiochemotherapy between January 2003 and September 2007, at the Institute of Oncology Ljubljana are presented. The treatment schedule consisted of 3-D conformal external beam radiotherapy (45 Gy in 25 fractions), with two cycles of concurrent chemotherapy (5-fluorouracil (5-FU) / Mitomycin C), followed by brachytherapy or external beam boost (15-30 Gy) to the primary tumor. Locoregional control (LRC), disease-free survival (DFS), disease-specific survival (DSS), overall survival (OS) and colostomy-free survival (CFS) rates and the rate of acute and chronic side-effects were estimated. The impact of individual tumor- and therapy-related factors on treatment outcome was assessed.

Treatment was completed according to the protocol in 72% of patients. The median follow-up time of 40 survivors was 22 months (range 1.7-53.2 months). At 2 years, LRC, DFS, DSS, OS and CFS rates were 68%, 67%, 87%, 76% and 85%, respectively. In the multivariate analysis, nodal stage was identified as an independent prognostic factor for LRC, DSS and CFS and application of Mitomycin C for OS. The most frequent acute side-effect of treatment was radiodermatitis (grade 3 in 66% of patients, grade 4 in 2%). Late anal stenosis, chronic ulceration and grade 2-3 incontinence developed in 3 (6 %), 2 (4 %) and 5 (10 %) of colostomy-free survivors, respectively.

Radiotherapy with concurrent 5-FU / Mitomycin C chemotherapy is feasible, with acceptable toxicity. The presented treatment outcome is comparable to other published results.
