  abstract  = {In der vorliegenden Arbeit konnten 52 von 103 Patientinnen, die in der Zeit von 1989 bis 1995 aufgrund einer Anorexia nervosa an der Universit{\"a}tsklinik f{\"u}r Kinder- und Jugendpsychiatrie W{\"u}rzburg station{\"a}r behandelt worden waren, nach im Mittel 5,3 Jahren pers{\"o}nlich nachuntersucht werden. Schwerpunkte der Studie waren der Langzeitverlauf der Knochendichte nach einer Erkrankung an Anorexia nervosa und m{\"o}gliche Einflussfaktoren auf die Knochendichteentwicklung. Es wurde untersucht, in wieweit sich Krankheitsverlauf, Heilungserfolg, {\"O}strogensubstitution, Amenorrhoedauer sowie sportliche Bet{\"a}tigung auf die Entwicklung der Knochendichteparameter auswirkten. Im Gegensatz zu den meisten vorhergehenden Verlaufsstudien wurde eine relativ große Patientinnengruppe, die alle im Kindes- und Jugendalter erkrankt waren und {\"u}ber Ausgangsdaten bez{\"u}glich der Knochendichte verf{\"u}gten, pers{\"o}nlich nachuntersucht. Neben verschiedenen klinischen Parametern wurde die Knochendichte mittels pQCT und DEXA bestimmt. Es zeigte sich, dass Knochendichteverluste noch ver{\"a}nderbar waren und die jungen Frauen teilweise eine g{\"u}nstige Knochendichteentwicklung aufwiesen. Positiv wirkte sich vor allem ein g{\"u}nstiger Heilungsverlauf aus. Im Gegensatz dazu fand sich bei Patientinnen mit chronischem Krankheitsverlauf eine sehr ung{\"u}nstige Knochendichteentwicklung. Nicht ganz so positiv stellt sich die Restitution der Knochenarchitektur dar. Insgesamt ließ sich kein eindeutiger Einfluss einer {\"O}strogensubstitution nachweisen. Positive Tendenzen waren bez{\"u}glich der Knochendichteentwicklung im Zusammenhang mit sportlicher Aktivit{\"a}t zu beobachten. Die Ergebnisse zeigen, dass eine z{\"u}gige und anhaltende Gesundung der Patientinnen den einzig nachweislich positiven Einflussfaktor auf die Knochendichteentwicklung darstellt. In wieweit die Einflussgr{\"o}ßen sportliche Aktivit{\"a}t und {\"O}strogensubstitution sich g{\"u}nstig auswirken, ließ sich nicht eindeutig kl{\"a}ren. Aus diesem Grund bedarf es weiterf{\"u}hrender prospektiver, randomisierter Studien, um die anorexieassoziierten Knochendichtever{\"a}nderungen und damit verkn{\"u}pfte Einflussfaktoren zu verstehen.},

  abstract  = {Epithelial-to-mesenchymal transition (EMT) is discussed to be centrally involved in invasion, stemness, and drug resistance. Experimental models to evaluate this process in its biological complexity are limited. To shed light on EMT impact and test drug response more reliably, we use a lung tumor test system based on a decellularized intestinal matrix showing more in vivo-like proliferation levels and enhanced expression of clinical markers and carcinogenesis-related genes. In our models, we found evidence for a correlation of EMT with drug resistance in primary and secondary resistant cells harboring KRAS\(^{G12C}\) or EGFR mutations, which was simulated in silico based on an optimized signaling network topology. Notably, drug resistance did not correlate with EMT status in KRAS-mutated patient-derived xenograft (PDX) cell lines, and drug efficacy was not affected by EMT induction via TGF-β. To investigate further determinants of drug response, we tested several drugs in combination with a KRAS\(^{G12C}\) inhibitor in KRAS\(^{G12C}\) mutant HCC44 models, which, besides EMT, display mutations in P53, LKB1, KEAP1, and high c-MYC expression. We identified an aurora-kinase A (AURKA) inhibitor as the most promising candidate. In our network, AURKA is a centrally linked hub to EMT, proliferation, apoptosis, LKB1, and c-MYC. This exemplifies our systemic analysis approach for clinical translation of biomarker signatures.},

  abstract  = {Background: Concomitant radiation with BRAF inhibitor (BRAFi) therapy may increase radiation-induced side effects but also potentially improve tumour control in melanoma patients. Methods: A total of 155 patients with BRAF-mutated melanoma from 17 European skin cancer centres were retrospectively analysed. Out of these, 87 patients received concomitant radiotherapy and BRAFi (59 vemurafenib, 28 dabrafenib), while in 68 patients BRAFi therapy was interrupted during radiation (51 vemurafenib, 17 dabrafenib). Overall survival was calculated from the first radiation (OSRT) and from start of BRAFi therapy (OSBRAFi). Results: The median duration of BRAFi treatment interruption prior to radiotherapy was 4 days and lasted for 17 days. Median OSRT and OSBRAFi in the entire cohort were 9.8 and 12.6 months in the interrupted group and 7.3 and 11.5 months in the concomitant group (P=0.075/P=0.217), respectively. Interrupted vemurafenib treatment with a median OSRT and OSBRAFi of 10.1 and 13.1 months, respectively, was superior to concomitant vemurafenib treatment with a median OSRT and OSBRAFi of 6.6 and 10.9 months (P=0.004/P=0.067). Interrupted dabrafenib treatment with a median OSRT and OSBRAFi of 7.7 and 9.8 months, respectively, did not differ from concomitant dabrafenib treatment with a median OSRT and OSBRAFi of 9.9 and 11.6 months (P=0.132/P=0.404). Median local control of the irradiated area did not differ in the interrupted and concomitant BRAFi treatment groups (P=0.619). Skin toxicity of grade ≥2 (CTCAE) was significantly increased in patients with concomitant vemurafenib compared to the group with treatment interruption (P=0.002). Conclusions: Interruption of vemurafenib treatment during radiation was associated with better survival and less toxicity compared to concomitant treatment. Due to lower number of patients, the relevance of treatment interruption in dabrafenib treated patients should be further investigated. The results of this analysis indicate that treatment with the BRAFi vemurafenib should be interrupted during radiotherapy. Prospective studies are desperately needed.},
