In Germany, the age-adjusted incidence of well-differentiated thyroid carcinoma in 2010 was 3.5 per 100 000 men and 8.7 per 100 000 women per year. Method: This review is based on randomized, controlled trials and multicenter trials on the treatment of well-differentiated thyroid carcinoma that were retrieved by a selective literature search, as well as on three updated guidelines issued in the past two years. Results: The recommended extent of surgical resection depends on whether the tumor is classified as low-risk or high-risk, so that papillary microcar cinomas, which carry a highly favorable prognosis, will not be overtreated. More than 90\% of localized, well-differentiated thyroid carcinomas can be cured with a combination of surgery and radioactive iodine therapy. Radio active iodine therapy is also effective in the treatment of well-differentiated thyroid carcinomas with distant metastases, yielding a 10-year survival rate of 90\%, as long as there is good iodine uptake and the tumor goes into remission after treatment; otherwise, the 10-year survival rate is only 10\%. In the past two years, better treatment options have become available for radioactive-iodine-resistant thyroid carcinoma. Phase 3 studies of two different tyrosine kinase inhibitors have shown that either one can markedly prolong progression-free survival, but not overall survival. Their more common clinically significant side effects are hand-foot syndrome, hypertension, diarrhea, proteinuria, and weight loss. Conclusion: Slow tumor growth, good resectability, and susceptibility to radioactive iodine therapy lend a favorable prognosis to most cases of well-differentiated thyroid carcinoma. The treatment should be risk-adjusted and interdisciplinary, in accordance with the current treatment guidelines. Even metastatic thyroid carcinoma has a favorable prognosis as long as there is good iodine uptake. The newly available medical treatment options for radioactive-iodine-resistant disease need to be further studied.}, language = {en} } @article{BaurSchedelbeckPulzeretal.2015, author = {Baur, Johannes and Schedelbeck, Ulla and Pulzer, Alina and Bluemel, Christina and Wild, Vanessa and Fassnacht, Martin and Steger, U.}, title = {A case report of a solitary pancreatic metastasis of an adrenocortical carcinoma}, series = {BMC Surgery}, volume = {15}, journal = {BMC Surgery}, number = {93}, doi = {10.1186/s12893-015-0076-3}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-126130}, year = {2015}, abstract = {Background Solitary metastases to the pancreas are rare. Therefore the value of resection in curative intention remains unclear. In the literature there are several promising reports about resection of solitary metastasis to the pancreas mainly of renal origin. Case presentation Here we report for the first time on the surgical therapy of a 1.5 cm solitary pancreatic metastasis of an adrenocortical carcinoma. The metastasis occurred almost 6 years after resection of the primary tumor. A partial pancreatoduodenectomy was performed and postoperatively adjuvant mitotane treatment was initiated. During the follow-up of 3 years after surgery no evidence of tumor recurrence occurred. Conclusion Resection of pancreatic tumors should be considered, even if the mass is suspicious for metastatic disease including recurrence of adrenocortical cancer.}, language = {en} } @article{MontesCobosLiFischeretal.2015, author = {Montes-Cobos, Elena and Li, Xiao and Fischer, Henrike J. and Sasse, Andr{\´e} and K{\"u}gler, Sebastian and Didi{\´e}, Michael and Toischer, Karl and Fassnacht, Martin and Dressel, Ralf and Reichardt, Holger M.}, title = {Inducible Knock-Down of the Mineralocorticoid Receptor in Mice Disturbs Regulation of the Renin-Angiotensin-Aldosterone System and Attenuates Heart Failure Induced by Pressure Overload}, series = {PLoS One}, volume = {10}, journal = {PLoS One}, number = {11}, doi = {10.1371/journal.pone.0143954}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-137575}, pages = {e0143954}, year = {2015}, abstract = {Mineralocorticoid receptor (MR) inactivation in mice results in early postnatal lethality. Therefore we generated mice in which MR expression can be silenced during adulthood by administration of doxycycline (Dox). Using a lentiviral approach, we obtained two lines of transgenic mice harboring a construct that allows for regulatable MR inactivation by RNAi and concomitant expression of eGFP. MR mRNA levels in heart and kidney of inducible MR knock-down mice were unaltered in the absence of Dox, confirming the tightness of the system. In contrast, two weeks after Dox administration MR expression was significantly diminished in a variety of tissues. In the kidney, this resulted in lower mRNA levels of selected target genes, which was accompanied by strongly increased serum aldosterone and plasma renin levels as well as by elevated sodium excretion. In the healthy heart, gene expression and the amount of collagen were unchanged despite MR levels being significantly reduced. After transverse aortic constriction, however, cardiac hypertrophy and progressive heart failure were attenuated by MR silencing, fibrosis was unaffected and mRNA levels of a subset of genes reduced. Taken together, we believe that this mouse model is a useful tool to investigate the role of the MR in pathophysiological processes.}, language = {en} }
