RESUMO
DNA damage is one of the foremost mechanisms of irradiation at the biological level. After the first isolation of DNA by Friedrich Miescher in the 19th century, the structure of DNA was described by Watson and Crick. Several Nobel Prizes have been awarded for DNA-related discoveries. This review aims to describe the historical perspective of DNA in radiation biology. Over the decades, DNA damage has been identified and quantified after irradiation. Depending on the type of sensing, different proteins are involved in sensing DNA damage and repairing the damage, if possible. For double-strand breaks, the main repair mechanisms are non-homologous end joining and homologous recombination. Additional mechanisms are the Fanconi anaemia pathway and base excision repair. Different methods have been developed for the detection of DNA double-strand breaks. Several drugs have been developed that interfere with different DNA repair mechanisms, e.g., PARP inhibitors. These drugs have been established in the standard treatment of different tumour entities and are being applied in several clinical trials in combination with radiotherapy. Over the past decades, it has become apparent that DNA damage mechanisms are also directly linked to the immune response in tumours. For example, cytosolic DNA fragments activate the innate immune system via the cGAS STING pathway.

OBJECTIVE: Germany's new medical licensure act has increased the importance of general practice in academic medical education. This study gives an overview of complementary and alternative medicine in general teaching practices in Germany and their adherence to evidence-based criteria which is required in order to qualify as a teaching practice. METHODS: After a systematic search for German teaching practices, we assessed their diagnostic and therapeutic offers via their websites. We calculated the various frequencies of treatments and differentiated between evidence-based complementary medicine and alternative medicine with little to no evidence. RESULTS: Of 4102 practices, more than half offered complementary and/or alternative treatment. Most of those were treatments approved of by the German medical association. Alternative medicine was offered by 18.2% of the practices. CONCLUSION: Collective terms and conflicting evidence complicate the classification of treatments. Teaching practices offering non-evidence-based treatment raise the question whether recruitment of additional teaching practices stands at odds with the quality of medical education. Explicit offers of alternative treatment should disqualify a teaching practice as such. Controversial treatment may be taught academically and during residency with a focus on evidence-based guidelines and communication skills in order to prepare young medical practitioners for talks with their patients about the subject.

PURPOSE: In less than one and a half year, the COVID-19 pandemic has nearly brought to a collapse our health care and economic systems. The scientific research community has concentrated all possible efforts to understand the pathogenesis of this complex disease, and several groups have recently emphasized recommendations for nutritional support in COVID-19 patients. In this scoping review, we aim at encouraging a deeper appreciation of magnesium in clinical nutrition, in view of the vital role of magnesium and the numerous links between the pathophysiology of SARS-CoV-2 infection and magnesium-dependent functions. METHODS: By searching PubMed and Google Scholar from 1990 to date, we review existing evidence from experimental and clinical studies on the role of magnesium in chronic non-communicable diseases and infectious diseases, and we focus on recent reports of alterations of magnesium homeostasis in COVID-19 patients and their association with disease outcomes. Importantly, we conduct a census on ongoing clinical trials specifically dedicated to disclosing the role of magnesium in COVID-19. RESULTS: Despite many methodological limitations, existing data seem to corroborate an association between deranged magnesium homeostasis and COVID-19, and call for further and better studies to explore the prophylactic or therapeutic potential of magnesium supplementation. CONCLUSION: We propose to reconsider the relevance of magnesium, frequently overlooked in clinical practice. Therefore, magnesemia should be monitored and, in case of imbalanced magnesium homeostasis, an appropriate nutritional regimen or supplementation might contribute to protect against SARS-CoV-2 infection, reduce severity of COVID-19 symptoms and facilitate the recovery after the acute phase.

PURPOSE: Serum magnesium is the most frequently used laboratory test for evaluating clinical magnesium status. Hypomagnesemia (low magnesium status), which is associated with many chronic diseases, is diagnosed using the serum magnesium reference range. Currently, no international consensus for a magnesemia normal range exists. Two independent groups designated 0.85 mmol/L (2.07 mg/dL; 1.7 mEq/L) as the low cut-off point defining hypomagnesemia. MaGNet discussions revealed differences in serum magnesium reference ranges used by members' hospitals and laboratories, presenting an urgent need for standardization. METHODS: We gathered and compared serum magnesium reference range values from our institutions, hospitals, and colleagues worldwide. RESULTS: Serum magnesium levels designating "hypomagnesemia" differ widely. Of 43 collected values, only 2 met 0.85 mmol/L as the low cut-off point to define hypomagnesemia. The remainder had lower cut-off values, which may underestimate hypomagnesemia diagnosis in hospital, clinical, and research assessments. Current serum magnesium reference ranges stem from "normal" populations, which unknowingly include persons with chronic latent magnesium deficit (CLMD). Serum magnesium levels of patients with CLMD fall within widely used "normal" ranges, but their magnesium status is too low for long-term health. The lower serum magnesium reference (0.85 mmol/L) proposed specifically prevents the inclusion of patients with CLMD. CONCLUSIONS: Widely varying serum magnesium reference ranges render our use of this important medical tool imprecise, minimizing impacts of low magnesium status or hypomagnesemia as a marker of disease risk. To appropriately diagnose, increase awareness of, and manage magnesium status, it is critical to standardize lower reference values for serum magnesium at 0.85 mmol/L (2.07 mg/dL; 1.7 mEq/L).

The paper "Combating COVID-19 and Building Immune Resilience: A Potential Role for Magnesium Nutrition?" by TC Wallace, which was published in the Journal of the American College of Nutrition highlights the importance of adequate magnesium (Mg) supply in relation to COVID-19. Wallace notes that Mg deficiency is associated with low-grade chronic inflammation. Furthermore, hypokalemia and a lack of active Vitamin D are consequences of a Mg deficit. In this way, Mg deficiency may exacerbate the course of COVID-19. Therefore, in patients with Covid-19 permanent monitoring of the Mg status and, if necessary, supplementation should be carried out. The possible importance of Mg in COVID-19 was only recently discussed also by Iotti et al. and the German Society for Magnesium Research e.V. Considering the meaningful connections between Mg and COVID-19 there are relevant research topics that should be addressed: Does Mg deficiency increase the risk of infection with COVID-19 or the risk of a severe course of the disease? Is there an increased prevalence of Mg deficiency in COVID-19 patients? Could Mg supplementation alleviate the course of the disease in COVID-19 or reduce complications? Does pharmacological induction of hypermagnesemia via intravenous Mg provide clinical benefits for COVID-19 patients in the intensive care unit (for example with regard to lung function or thromboembolism)?

PURPOSE: This article reports on the long-term impact of radiotherapy adapted to stage, histology, and previous resection in a large cohort of patients with intestinal lymphoma (iL) treated with definitive or adjuvant curative-intent radiation therapy (RT) ± chemotherapy (CHOP, MCP, or COP). PATIENTS AND METHODS: In two consecutive prospective study designs, 134 patients with indolent (stage IE-IIE) or aggressive (stage IE-IVE) iL were referred to 61 radiotherapeutic institutions between 1992 and 2003. Patients with indolent iL received extended field (EF) 30 Gy (+10 Gy boost in definitive treatment); patients with aggressive iL received involved field (IF) (EF) 40 Gy by means of stage-, histology-, and operation-adapted radiation fields. RESULTS: The patients had median age 58 years and were predominantly male (2:1). Histology showed aggressive prevalence (1.6:1), stage IE-to-stage IIE ratio of iL 1.04:1, and localized stages-to-advanced stages ratio of aggressive lymphoma 23:1. Median follow-up was in total 11.7 years: 10.0 years in the first study, GIT (GastroIntestinal-Tract) 1992, and 11.8 years in the second study, GIT 1996. Lymphoma involvement was predominantly a single intestinal lesion (82.1%). Decrease of radiation field size from EF to IF in stage I aggressive iL from GIT 1992 to GIT 1996 resulted in a nonsignificant partial reduction of chronic toxicity while maintaining comparable survival rates (5-year overall survival 87.9 vs. 86.7%, 10-year overall survival 77.4 vs. 71.5%) with nonsignificant difference in event-free survival (5-year event-free survival 82.6 vs. 86.7%, 10-year event-free survival 69.7 vs. 71.5%) and lymphoma-specific survival (5-year lymphoma-specific survival 90.1 vs. 91.9%, 10-year lymphoma-specific survival 87.6% vs. 91.9%). Comparative dose calculation of two still available indolent duodenal lymphoma computed tomography scans revealed lower radiation exposure to normal tissues from applying current standard involved site RT (ISRT) 30 Gy in both cases. CONCLUSION: RT adapted to stage, histology, and resection in multimodal treatment of iL, despite partially decreasing field size (EF to IF), achieves excellent local tumor control and survival rates. The use of modern RT technique and target volume with ISRT offers the option of further reduction of normal tissue complication probability. IMPLICATIONS FOR PRACTICE: Although patients with intestinal lymphoma (iL) are heterogeneous according to histology and subtype, they benefit from radiotherapy. Prospective study data from 134 patients with indolent iL (stage IE-IIE) or aggressive iL (stage IE-IVE) show 100% tumor control after definitive or adjuvant curative-intent radiation therapy ± chemotherapy. Radiation treatment was applied between 1992 and 2003. Median follow-up in total was 11.7 years. No radiotherapy-associated death occurred. Relapse developed in 15.7% of the entire cohort; distant failure was more frequent than local (4:1). Normal tissue complication probability can be further improved using modern involved site radiation therapy techniques.

PURPOSE: The aim of this retrospective clinical quality assessment was to evaluate the efficacy of low-dose radiotherapy (RT) for painful benign skeletal disorders. METHODS: Patients with different painful benign skeletal disorders (arthrosis and enthesopathies) were recruited for this retrospective clinical quality assessment between January 2014 and December 2015. RT was applied with a linear accelerator. Single doses of 0.5â¯Gy (total dose 3.0-5.0â¯Gy) were used. Pain was measured before and immediately after RT (early response) by a 10-point visual analogue scale (VAS). We defined a VAS score of 0-2 as a good response. Pain relief was measured during follow-up. RESULTS: A total of 598 evaluable patients (394 females, 204 males) with a mean age of 61.4 years (range 33-81 years) were recruited. The median VAS score was 7.0 (interquartile range [IQR] 2) before treatment and 5.0 (IQR 4) upon completion of RT (pâ¯< 0.001). A good response was achieved upon completion of RT in 83 patients (13.9%), with a median follow-up of 38 months (range 29-47 months) in 373 patients (62.4%; pâ¯< 0.001). In general, RT had a better effect on enthesopathies than on arthrosis. CONCLUSION: Low-dose RT is a very effective treatment for the management of painful benign skeletal disorders. Due to the delayed onset of analgesic effects, low-dose RT results in significantly improved long-term efficacy compared to the results immediately after RT. These findings confirm the results of other retrospective, prospective, and randomized trials.

PURPOSE: Long-term impact of stage-adapted field reduction in a large cohort of gastric marginal zone lymphoma (gMZL) patients treated conservatively with curative radiation therapy (RT). PATIENTS AND METHODS: Prospective analysis of paper records of 290 patients with stage IE-IIE gMZL, treated in 78 radiotherapeutic institutions in Germany from 1992-2013. Stage-adapted radiation fields decreased from extended field (EF) to involved field (IF) over the course of three consecutive prospective trials of the German Study Group on Gastrointestinal Lymphoma (DSGL). Treatment results were compared between the three cohorts. RESULTS: Overall collective with median age of 60 years, slight male predominance (m:fâ¯= 1.1:1) and ratio of disease stage I:stage IIâ¯= 2.1:1. Median follow-up 6.4 years in total: 13.0 years in the first gastrointestinal study (GIT 1992), 8.2 years in the second (GIT 1996) and 4.7 years in the third study (DSGL 01/2003). Stage-adapted radiation field decrease together with further technological development led to reduced relative frequencies of acute/chronic adverse effects and until now was accompanied by lower disease recurrence. The third study design with smallest field size (IF in stage I, locoregional EF in stage II) achieved the best survival outcome at the 5year follow-up (overall survival 92.7%, event-free survival 89.5% and lymphoma-specific survival 100.0%). Disease relapse observed in 10 patients. Cumulative incidence of disease-specific death was 1.7% of the followed patients. Primary disease stage associated with lymphoma-specific survival. CONCLUSION: Stage-adapted reduction towards IF in gMZL resulted in favorable adverse effects, local control and survival rates. These results support further decreases in modern RT of gMZL.

PURPOSE: We aim to introduce and discuss the statements and recommendations of the German S3 guideline on renal cell cancer for daily practice of radiation oncologists. METHODS: This report comprises indication, treatment decision, dose prescription and current literature including treatment of oligometastatic disease. RESULTS: According to different stages of the disease and the structure of the guideline we focus on five treatment situations and recommendations for decision making: (1) Neo-/adjuvant treatment before or after nephrectomy: No indication for radiotherapy. (2) Small renal mass: Stereotactic ablative radiotherapy is currently seen as experimental option due to small patient numbers reported in the literature. However, local tumor control achieved by SBRT appears favourable with >90% at 2 years. (3) Oligometastasis: Radiation treatment with higher local doses or stereotactic treatment is possible after interdisciplinary discussion. Indications for palliative (4) and symptomatic treatment (5) are not different compared to other tumor entities. CONCLUSION: Currently, there is no evidence-based indication for radiation treatment in the primary setting (adjuvant/neoadjuvant or definitive) of renal cell cancer. In the future stereotactic radiotherapy should have a stronger role in the treatment of medically inoperable patients with primary renal cell cancer and especially in the setting of oligometastasis.

BACKGROUND: Aneurysmal bone cysts (ABC) are rapidly growing benign osseous lesions composed of blood-filled channels separated by fibrous septa. Since the value of external beam radiotherapy (EBRT) for ABC has not been well defined, the German Cooperative Group on Radiotherapy for Benign Diseases performed the national register study described herein. PATIENTS AND METHODS: Five German institutions collected data regarding clinical features, treatment concepts, and outcome for patients with ABC who had been referred for local EBRT over the past 30 years. RESULTS: Between 1990 and 2015, 10 patients with ABC were irradiated (5 female/5 male). Median age was 23 years (range 14-40 years). Involved sites were: spine (n = 3), sacrum/pelvis (n = 2), shoulder/scapula (n = 2), humerus (n = 1), femur (n = 1), and radius (n = 1). The median EBRT total and fractional doses were 28 Gy (range 5-40 Gy) and 2 Gy (range 1-2 Gy), respectively. Median follow-up was 65 months (range 12-358 months). Persistent pain relief was achieved for all patients. However, long-term follow-up response data were only available for 7/10 patients. All 7 patients exhibited a radiological response and experienced no recurrent disease activity or pain during follow-up. Acute and late radiogenic toxicities ≥ grade 3 and secondary malignancies were also not observed. CONCLUSION: Primary or adjuvant EBRT seems to be an effective and safe treatment option for persistent or recurrent ABC. Fractionated doses below 30 Gy may be recommended.

OBJECTIVE: To analyze the financial burden of complementary and alternative medicine (CAM) in cancer treatment. MATERIALS AND METHODS: Based on a systematic search of the literature (Medline and the Cochrane Library, combining the MeSH terms 'complementary therapies', 'neoplasms', 'costs', 'cost analysis', and 'cost-benefit analysis'), an expert panel discussed different types of analyses and their significance for CAM in oncology. RESULTS: Of 755 publications, 43 met our criteria. The types of economic analyses and their parameters discussed for CAM in oncology were cost, cost-benefit, cost-effectiveness, and cost-utility analyses. Only a few articles included arguments in favor of or against these different methods, and only a few arguments were specific for CAM because most CAM methods address a broad range of treatment aim parameters to assess effectiveness and are hard to define. Additionally, the choice of comparative treatments is difficult. To evaluate utility, healthy subjects may not be adequate as patients with a life-threatening disease and may be judged differently, especially with respect to a holistic treatment approach. We did not find any arguments in the literature that were directed at the economic analysis of CAM in oncology. Therefore, a comprehensive approach assessment based on criteria from evidence-based medicine evaluating direct and indirect costs is recommended. CONCLUSION: The usual approaches to conventional medicine to assess costs, benefits, and effectiveness seem adequate in the field of CAM in oncology. Additionally, a thorough deliberation on the comparator, endpoints, and instruments is mandatory for designing studies.

BACKGROUND AND PURPOSE: Radiation therapy (RT) is an established and effective treatment modality in the management of a large variety of hyperproliferative disorders and benign neoplasms. Objective of this article is to summarize the updated DEGRO consensus S2e guideline recommendations. MATERIALS AND METHODS: This report comprises an overview of the relevant aspects of the updated guidelines with regard to treatment decision, dose prescription, and RT technique for a selected group of disorders including Morbus Dupuytren (MD)/Morbus Ledderhose (ML), keloids, Peyronie's disease (induratio penis plastica, IPP), desmoid tumors, pigmented villonodular synovitis (PVNS), symptomatic vertebral hemangiomas (sVH), and Gorham-Stout syndrome (GSS). On the basis of results in the literature, we attempted to classify the level of evidence (LoE) and the grade of recommendation (GR) according to the Oxford criteria. RESULTS: There is comprehensive evidence in the literature that RT is a reasonable and effective treatment modality for the treatment of all the above-mentioned disorders. The LoE varies from 2c to 4, and GR varies from A to C. CONCLUSIONS: The use of RT can be recommended for the interdisciplinary management of most of the reported disorders. It can be used in the primary treatment approach and as an effective adjunct to other treatment modalities or in some indications as a valuable alternative treatment option. We hope that the updated DEGRO S2e consensus guideline recommendations are a helpful tool for radiation oncologists in the clinical decision-making process.

INTRODUCTION: Attendance of staff and use of resources during treatment have an impact on costs. For palliative radiotherapy, no reliable data are available on the subject. Therefore, the measurement of selected variables (staff absorbance and room occupancy) based on daily palliative irradiation was the aim of our prospective study. The analysis is part of a larger study conducted by the German Society of Radiation Oncology (DEGRO). PATIENTS, MATERIAL, AND METHODS: A total of 172 palliative radiation treatments were followed up prospectively between October 2009 and March 2010. The study was performed at two experienced radiotherapy departments (Herne and Bielefeld) and evaluated the attendance of medical personnel and room occupancy related to the selected steps of the treatment procedure: treatment planning and daily application of radiation dose. RESULTS: Computed tomography for treatment planning engaged the unit for 19 min (range: 17-22 min). The localization of target volume required on average 28 min of a technician's working time. The mean attendance of the entire staff (radiation oncologist, physicist, technician) for treatment planning was 159 min, while the total room occupancy was 140 min. Depending on the type of treatment, the overall duration of a radiotherapy session varied on average between 8 and 18 min. The staff was absorbed by the first treatment session (including portal imaging) for 8-27 min. Mean room occupancy was 18 min (range: 6-65 min). The longest medical staff attendance was observed during an initial irradiation session (mean: 11 min). Radiotherapy sessions with weekly performed field verifications occupied the rooms slightly longer (mean: 10 min, range: 4-25 min) than daily radiotherapy sessions (mean: 9 min, range: 3-29 min). We observed that the patients' symptoms, their condition, and their social environment confounded the time schedule. CONCLUSIONS: Target localization, treatment planning, and performance of palliative radiotherapy absorb resources to an extent comparable to nonpalliative treatment. Because of unexpected events, the time schedule before and during radiotherapy may reveal strong interindividual variability.

INTRODUCTION: Cancer diagnoses are constantly increasing in clinical practice. Therefore, more and more patients are interested in how they can actively participate in the process of treatment. Spirituality represents a hidden issue of the population, which counts as a branch of complementary and alternative treatment. Therefore, the aim of our study was to investigate whether there are associations between spirituality and demographic and psychosocial factors, as well as religious beliefs, in cancer patients. METHODS: We conducted a survey with 451 participants in 10 oncology centers between March and July 2021. A composition of the following 9 different questionnaires was used to collect data on spirituality, demographics, resilience, self-efficiency, life satisfaction, and sense of coherence: Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being (FACIT-Sp12), General Life Satisfaction Short Scale (L-1), Resilienzskala Kurzform (RS-13), Sense of Coherence Scale - Leipziger Kurzform (SOC-L9), Allgemeine Selbstwirksamkeit Kurzskala (AKSU), Adolescent Food Habits Checklist, Likert-Scale of daily activities, questionnaire of the Working group Prävention und Integrative Onkologie (PRiO), and personal opinion on the cause of the disease. Calculated data and analyzed group differences using ANOVA Bonferroni were used to test associations between spirituality and the variables studied. For more detailed examination of spirituality, we took a closer look at the different components of spirituality - peace, meaning, and faith - and their relation to each other (three-factor spirituality analyses). RESULTS: Higher spirituality scores in total as well as meaning, peace, and faith were each associated with higher levels of resilience and life satisfaction. Higher religious belief was found to be associated with higher spiritual attitudes. High personal self-efficiency was found in people with higher spiritual beliefs in general as well as higher meaning and peace. Meaning and peace emerge as essential components of spiritual well-being and show a stronger association with expressions of general spirituality than faith. CONCLUSION: Spirituality takes a crucial role among the resources of life-threatening diseases. As such, further research is needed to expand and integrate patient options into a modernized concept of care. Our data indicate that higher spiritual well-being is associated with a more tolerant approach to illness. Thus, addressing spiritual needs in therapy is associated with better psychological adjustment to the individual situation and reduces negative distress. To promote spiritual needs in the future, cognitive as well as affective components of spirituality should be emphasized.

BACKGROUND: Many cancer patients use complementary and alternative medicine (CAM). Most websites offering online information on CAM are not helpful for them. METHODS: We extracted decisive elements for online information on CAM by analyzing the literature on the information needs of cancer patients and on counseling cancer patients on CAM. RESULTS: Key issues for online information on CAM are the qualification of the authors, transparency and accountability of the information, description of the aims, a scientific approach, description of treatment alternatives, support for the patient-physician relationship, individualized information, a summary of the information, disclosure of funding, and the privacy policy. CONCLUSIONS: The communicative challenge will be to convey information without destroying hope and motivation. We suggest that CAM topics should be integrated into broader information provided on cancer (etiology, conventional treatment). By also providing information for physicians, such a website could promote shared decision-making. Online information will gain the status of independent expert knowledge if provided by a well-known scientific organization as, e.g., a national cancer society.

OBJECTIVE: Are there any evidence-based medicine (EBM)-supported treatment approaches of complementary and alternative medicine (CAM) methods for urological oncologists? METHODS: We reviewed the actual German S3 guidelines "Supportive Care" and "Complementary Medicine" as well as the online-tool Onkopedia for recommendations about essential trace elements (Zn, Se, Mn, Fe), vitamins (A, B, C, D, E), and electrolytes (Mg, Ca). Furthermore, we added results of randomized trials to present potential future developments. RESULTS: Each therapy with micronutrients should be based on laboratory observation of a deficit. There are selected guideline recommendations for selenium, iron and vitamin D. Potential indications were registered for manganese, vitamin A derivates, and vitamin C. No benefit was observed for vitamin B, zinc, and vitamin E. CONCLUSION: Micronutrients should be substituted in the case of deficit. General supplementation of daily nutrition is not recommended for cancer patients.

A large amount of published research points to the interesting concept (hypothesis) that magnesium (Mg) status may have relevance for the outcome of COVID-19 and that Mg could be protective during the COVID disease course. As an essential element, Mg plays basic biochemical, cellular, and physiological roles required for cardiovascular, immunological, respiratory, and neurological functions. Both low serum and dietary Mg have been associated with the severity of COVID-19 outcomes, including mortality; both are also associated with COVID-19 risk factors such as older age, obesity, type 2 diabetes, kidney disease, cardiovascular disease, hypertension, and asthma. In addition, populations with high rates of COVID-19 mortality and hospitalization tend to consume diets high in modern processed foods, which are generally low in Mg. In this review, we review the research to describe and consider the possible impact of Mg and Mg status on COVID-19 showing that (1) serum Mg between 2.19 and 2.26 mg/dL and dietary Mg intakes > 329 mg/day could be protective during the disease course and (2) inhaled Mg may improve oxygenation of hypoxic COVID-19 patients. In spite of such promise, oral Mg for COVID-19 has thus far been studied only in combination with other nutrients. Mg deficiency is involved in the occurrence and aggravation of neuropsychiatric complications of COVID-19, including memory loss, cognition, loss of taste and smell, ataxia, confusion, dizziness, and headache. Potential of zinc and/or Mg as useful for increasing drug therapy effectiveness or reducing adverse effect of anti-COVID-19 drugs is reviewed. Oral Mg trials of patients with COVID-19 are warranted.
