Publications on radiotherapy (RT) are scarce. This review summarizes the current data on RT for pACC and possibly provides first evidence to justify its use in this setting. Materials and methods We searched the PubMed and Embase database for manuscripts regarding RT for pACC. Results We included 17 manuscripts reporting on 76 patients treated with RT, after screening 2961 references and 269 full articles. In addition, we added data of 4 unreported pACC patients treated by co-authors. All reports based on retrospective data. Median age at first diagnosis was 11.1 years (70\% female); 78\% of patients presented with hormonal activity. RT was mostly performed for curative intent (78\%). 88\% of RT were administered during primary therapy. The site of RT was predominantly the local tumor bed (76\%). Doses of RT ranged from 15 to 62 Gy (median 50 Gy). Information on target volumes or fractionation were lacking. Median follow-up was 6,9 years and 64\% of the patients died of disease, with 33\% alive without disease. In 16 of 48 patients with available follow-up data after adjuvant RT (33\%) no recurrence was reported and in 3 of 9 patients palliative RT seemed to induce some benefit for the patient. Conclusions Our first systematic review on RT for pACC provides too few data for any general recommendation, but adjuvant RT in patients with high risk might be considered. International collaborative studies are urgently needed to establish better evidence on the role of RT in this rare malignancy.}, language = {en} } @article{WiedmannHeuschmannHermanek2015, author = {Wiedmann, Silke and Heuschmann, Peter U. and Hermanek, Peter}, title = {In reply: The quality of acute stroke treatment-an analysis of evidence-based indicators in 260 000 patients}, series = {Deutsches Aerzteblatt International}, volume = {112}, journal = {Deutsches Aerzteblatt International}, doi = {10.3238/arztebl.2015.0288b}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-148666}, pages = {288}, year = {2015}, abstract = {No abstract available.}, language = {en} } @article{WeidnerRousseauPlauthetal.2016, author = {Weidner, Christopher and Rousseau, Morten and Plauth, Annabell and Wowro, Sylvia J. and Fischer, Cornelius and Abdel-Aziz, Heba and Sauer, Sascha}, title = {Iberis amara Extract Induces Intracellular Formation of Reactive Oxygen Species and Inhibits Colon Cancer}, series = {PLoS ONE}, volume = {11}, journal = {PLoS ONE}, number = {4}, doi = {10.1371/journal.pone.0152398}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-167044}, pages = {e0152398}, year = {2016}, abstract = {Massively increasing global incidences of colorectal cancer require efficient treatment and prevention strategies. Here, we report unexpected anticancerogenic effects of hydroethanolic Iberis amara extract (IAE), which is known as a widely used phytomedical product for treating gastrointestinal complaints. IAE significantly inhibited the proliferation of HT-29 and T84 colon carcinoma cells with an inhibitory concentration (IC\(_{50}\)) of 6 and 9 μg/ml, respectively, and further generated inhibitory effects in PC-3 prostate and MCF7 breast cancer cells. Inhibition of proliferation in HT-29 cells was associated with a G2/M phase cell cycle arrest including reduced expression of various regulatory marker proteins. Notably, in HT-29 cells IAE further induced apoptosis by intracellular formation of reactive oxygen species (ROS). Consistent with predictions derived from our in vitro experiments, bidaily oral gavage of 50 mg/kg of IAE over 4 weeks resulted in significant inhibition of tumor growth in a mouse HT-29 tumor xenograft model. Taken together, Iberis amara extracts could become useful alternatives for preventing and treating the progression of colon cancer.}, language = {en} } @article{Reiners2011, author = {Reiners, Christoph}, title = {Clinical Experiences with Radiation Induced Thyroid Cancer after Chernobyl}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-75475}, year = {2011}, abstract = {The risk of developing thyroid cancer increases considerably after exposure to external or internal radiation, especially in children below the age of 10. After the Chernobyl reactor accident, the yearly incidence of childhood thyroid cancer in Belarus increased to approximately 40 per 1.000.000 in girls and to roughly 20 per 1.000.000 in boys compared to approximately 0.5 cases per 1.000.000 prior to the accident. Typically, young children with thyroid cancer after radiation exposure present in ≈95\% of the cases as papillary cancers, in ≈50\% as invasive tumors growing outside the thyroid capsule, in ≈65\% with lymph node metastases and in ≈15\% with distant metastases. A joint Belarusian-German project starting in April 1993 that combined treatment with surgery and radioiodine was organized in 237 selected children from Belarus who were exposed to the Chernobyl fallout and had advanced stages of thyroid cancer. The study group included 141 girls and 96 boys. Their median age at the time of the accident was 1.7 years; whereas the median age at the time of diagnosis was 12.4 years. With the exception of two cases with follicular histology, the majority of the patients had been diagnosed with papillary thyroid cancers. In 63\%, the tumor had grown outside the thyroid capsule and invaded the tissue of the neck (pT4). Nearly all of the selected cases (96\%) showed-up with lymph node metastases (pN1) and 43\% of the patients with distant metastases mainly to the lungs (pM1). In 58\% of the children, complete remissions of thyroid cancer could be achieved until December 31st 2010 and in 34\% of the children, stable partial remissions; in the remaining 8\% of the patients, partial remissions were observed. The risk of radiation-induced thyroid cancer increased considerably in children and adolescents who were affected by the Chernobyl reactor accident. In spite of the fact, that thyroid cancers in young children seem to behave more aggressively than in older patients, the results of combined treatment with thyroidectomy, radioiodine therapy and thyroid hormone replacement are excellent.}, subject = {Chernobyl}, language = {en} } @article{MemmelSisarioZoelleretal.2017, author = {Memmel, Simon and Sisario, Dmitri and Z{\"o}ller, Caren and Fiedler, Vanessa and Katzer, Astrid and Heiden, Robin and Becker, Nicholas and Eing, Lorenz and Ferreira, F{\´a}bio L.R. and Zimmermann, Heiko and Sauer, Markus and Flentje, Michael and Sukhorukov, Vladimir L. and Djuzenova, Cholpon S.}, title = {Migration pattern, actin cytoskeleton organization and response to PI3K-, mTOR-, and Hsp90-inhibition of glioblastoma cells with different invasive capacities}, series = {Oncotarget}, volume = {8}, journal = {Oncotarget}, number = {28}, doi = {10.18632/oncotarget.16847}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-170719}, pages = {45298-45310}, year = {2017}, abstract = {High invasiveness and resistance to chemo- and radiotherapy of glioblastoma multiforme (GBM) make it the most lethal brain tumor. Therefore, new treatment strategies for preventing migration and invasion of GBM cells are needed. Using two different migration assays, Western blotting, conventional and super-resolution (dSTORM) fluorescence microscopy we examine the effects of the dual PI3K/mTOR-inhibitor PI-103 alone and in combination with the Hsp90 inhibitor NVP-AUY922 and/or irradiation on the migration, expression of marker proteins, focal adhesions and F-actin cytoskeleton in two GBM cell lines (DK-MG and SNB19) markedly differing in their invasive capacity. Both lines were found to be strikingly different in morphology and migration behavior. The less invasive DK-MG cells maintained a polarized morphology and migrated in a directionally persistent manner, whereas the highly invasive SNB19 cells showed a multipolar morphology and migrated randomly. Interestingly, a single dose of 2 Gy accelerated wound closure in both cell lines without affecting their migration measured by single-cell tracking. PI-103 inhibited migration of DK-MG (p53 wt, PTEN wt) but not of SNB19 (p53 mut, PTEN mut) cells probably due to aberrant reactivation of the PI3K pathway in SNB19 cells treated with PI-103. In contrast, NVP-AUY922 exerted strong anti-migratory effects in both cell lines. Inhibition of cell migration was associated with massive morphological changes and reorganization of the actin cytoskeleton. Our results showed a cell line-specific response to PI3K/mTOR inhibition in terms of GBM cell motility. We conclude that anti-migratory agents warrant further preclinical investigation as potential therapeutics for treatment of GBM.}, language = {en} } @article{LoriniBescosAtinThavarajetal.2021, author = {Lorini, Luigi and Besc{\´o}s At{\´i}n, Coro and Thavaraj, Selvam and M{\"u}ller-Richter, Urs and Alberola Ferranti, Margarita and Pamias Romero, Jorge and S{\´a}ez Barba, Manel and de Pablo Garc{\´i}a-Cuenca, Alba and Bra{\~n}a Garc{\´i}a, Irene and Bossi, Paolo and Nuciforo, Paolo and Simonetti, Sara}, title = {Overview of oral potentially malignant disorders: from risk factors to specific therapies}, series = {Cancers}, volume = {13}, journal = {Cancers}, number = {15}, issn = {2072-6694}, doi = {10.3390/cancers13153696}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-242779}, year = {2021}, abstract = {Oral squamous cell carcinoma (OSCC) is a very aggressive cancer, representing one of the most common malignancies worldwide. Oral potentially malignant disorders (OPMDs) regroup a variegate set of different histological lesions, characterized by the potential capacity to transform in OSCC. Most of the risk factors associated with OSCC are present also in OPMDs' development; however, the molecular mechanisms and steps of malignant transformation are still unknown. Treatment of OSCC, including surgery, systemic therapy and radiotherapy (alone or in combination), has suffered a dramatic change in last years, especially with the introduction of immunotherapy. However, most cases are diagnosed during the advanced stage of the disease, decreasing drastically the survival rate of the patients. Hence, early diagnosis of premalignant conditions (OPMDs) is a priority in oral cancer, as well as a massive education about risk factors, the understanding of mechanisms involved in malignant progression and the development of specific and more efficient therapies. The aim of this article is to review epidemiological, clinical, morphological and molecular features of OPMDs, with the purpose to lay the foundation for an exhaustive comprehension of these lesions and their ability of malignant transformation and for the development of more effective and personalized treatments.}, language = {en} } @article{KingslakeDiasDawsonetal.2017, author = {Kingslake, Jonathan and Dias, Rebecca and Dawson, Gerard R. and Simon, Judit and Goodwin, Guy M. and Harmer, Catherine J. and Morriss, Richard and Brown, Susan and Guo, Boliang and Dourish, Colin T. and Ruh{\´e}, Henricus G. and Lever, Anne G. and Veltman, Dick J. and van Schaik, Anneke and Deckert, J{\"u}rgen and Reif, Andreas and St{\"a}blein, Michael and Menke, Andreas and Gorwood, Philip and Voegeli, G{\´e}raldine and Perez, Victor and Browning, Michael}, title = {The effects of using the PReDicT Test to guide the antidepressant treatment of depressed patients: study protocol for a randomised controlled trial}, series = {Trials}, volume = {18}, journal = {Trials}, doi = {10.1186/s13063-017-2247-2}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-173012}, year = {2017}, abstract = {Background Antidepressant medication is commonly used to treat depression. However, many patients do not respond to the first medication prescribed and improvements in symptoms are generally only detectable by clinicians 4-6 weeks after the medication has been initiated. As a result, there is often a long delay between the decision to initiate an antidepressant medication and the identification of an effective treatment regimen. Previous work has demonstrated that antidepressant medications alter subtle measures of affective cognition in depressed patients, such as the appraisal of facial expression. Furthermore, these cognitive effects of antidepressants are apparent early in the course of treatment and can also predict later clinical response. This trial will assess whether an electronic test of affective cognition and symptoms (the Predicting Response to Depression Treatment Test; PReDicT Test) can be used to guide antidepressant treatment in depressed patients and, therefore, hasten treatment response compared to a control group of patients treated as usual. Methods/design The study is a randomised, two-arm, multi-centre, open-label, clinical investigation of a medical device, the PReDicT Test. It will be conducted in five European countries (UK, France, Spain, Germany and the Netherlands) in depressed patients who are commencing antidepressant medication. Patients will be randomised to treatment guided by the PReDicT Test (PReDicT arm) or to Treatment as Usual (TaU arm). Patients in the TaU arm will be treated as per current standard guidelines in their particular country. Patients in the PReDicT arm will complete the PReDicT Test after 1 (and if necessary, 2) weeks of treatment. If the test indicates non-response to the treatment, physicians will be advised to immediately alter the patient's antidepressant therapy by dose escalation or switching to another compound. The primary outcome of the study is the proportion of patients showing a clinical response (defined as 50\% or greater decrease in baseline scores of depressionmeasured using the Quick Inventory of Depressive Symptoms - Self-Rated questionnaire) at week 8. Health economic and acceptability data will also be collected and analysed. Discussion This trial will test the clinical efficacy, cost-effectiveness and acceptability of using the novel PReDicT Test to guide antidepressant treatment selection in depressed patients.
