In the last decade, the development of new radiopharmaceuticals for the imaging and therapy of prostate cancer has been a highly active and important area of research, especially focusing on the prostate-specific membrane antigen (PSMA), an antigen which is upregulated in prostate, as well as in other tumor cells. A large variety of PSMA ligands have been radiolabeled, to date. Among the various derivatives, PSMA-617 resulted to be one of the most interesting in terms of interaction with the antigen and clinical properties, and its lutetium-177 labeled version has recently been approved by regulatory agencies for therapeutic purposes. For this reasons, the radiolabeling with fluorine-18 of a PSMA-617 derivative might be of interest. Beside other methodologies to radiolabel macromolecules with fluorine-18, the “click-chemistry” approach resulted to be very useful, and the copper-catalyzed azide-alkyne cycloaddition (CuAAC) is considered one of most efficient and reliable. This paper proposes the synthesis of a suitable precursor for the radiolabeling with fluorine-18 of a new PSMA-617 derivative. The whole radiosynthetic procedure has been fully automated, and the final product, which proved to be stable in plasma, has been obtained with radiochemical yield and purity suitable for subsequent preclinical studies. 相似文献

Background
Limited data exist on the clinical behavior of pediatric non-rhabdomyosarcoma soft tissue sarcomas (NRSTS) with distant metastases at onset, and a clear standard of care has not yet been defined.Methods
This cohort study reports on pediatric adult-type metastatic NRSTS enrolled in two concurrent prospective European studies, i.e., the randomized BERNIE study and the single-arm MTS 2008 study developed by the European paediatric Soft tissue sarcoma Study Group. Treatment programs were originally designed for patients with metastatic rhabdomyosarcoma, i.e., nine courses of multidrug chemotherapy (with or without bevacizumab in the BERNIE study), followed by 12 cycles of maintenance therapy, whereas radiotherapy and/or surgery (on primary tumor and/or metastases) were delayed until after seven courses of chemotherapy had been administered.Results
The study included 61 patients <21 years old treated from July 2008 to December 2016. The lung was the site of metastases in 75% of the cases. All patients received multi-agent chemotherapy, 44% had local therapy to primary tumor, and 18% had treatment of metastases. Median time to progression/relapse was 6 months. A high rate of tumor progression was observed during the initial part of the chemotherapy program. With a median follow-up of 41.5 months (range, 2–111 months), 3-year event-free survival and overall survival were 15.4% (95% confidence interval [CI], 7.6–25.7) and 34.9% (95% CI, 22.7–47.5), respectively. There were no statistically significant differences in outcome depending on the type of treatment administered.Conclusions
The study confirmed the overall poor outcome for patients with metastatic NRSTS, whose treatment remains a challenge.Plain Language Summary
- Pediatric non-rhabdomyosarcoma soft tissue sarcomas form a heterogeneous group of rare tumors.
- Although recent international studies have defined the standard of care for patients with localized disease, limited data are available on the clinical behavior of patients with distant metastases.
- This study on 61 metastatic cases treated on two prospective European protocols confirms that the chances of survival of such patients are often dismal and a standard treatment is still lacking.

In this paper, several radiomics-based predictive models of response to induction chemotherapy (IC) in sinonasal cancers (SNCs) are built and tested. Models were built as a combination of radiomic features extracted from three types of MRI images: T1-weighted images, T2-weighted images and apparent diffusion coefficient (ADC) maps. Fifty patients (aged 54 ± 12 years, 41 men) were included in this study. Patients were classified according to their response to IC (25 responders and 25 nonresponders). Not all types of images were acquired for all of the patients: 49 had T1-weighted images, 50 had T2-weighted images and 34 had ADC maps. Only in a subset of 33 patients were all three types of image acquired. Eighty-nine radiomic features were extracted from the MRI images. Dimensionality reduction was performed by using principal component analysis (PCA) and by selecting only the three main components. Different algorithms (trees ensemble, K-nearest neighbors, support vector machine, naïve Bayes) were used to classify the patients as either responders or nonresponders. Several radiomic models (either monomodality or multimodality obtained by a combination of T1-weighted, T2-weighted and ADC images) were developed and the performance was assessed through 100 iterations of train and test split. The area under the curve (AUC) of the models ranged from 0.56 to 0.78. Trees ensemble, support vector machine and naïve Bayes performed similarly, but in all cases ADC-based models performed better. Trees ensemble gave the highest AUC (0.78 for the T1-weighted+T2-weighted+ADC model) and was used for further analyses. For trees ensemble, the models based on ADC features performed better than those models that did not use those features (P < 0.02 for one-tail Hanley test, AUC range 0.68–0.78 vs 0.56–0.69) except the T1-weighted+ADC model (AUC 0.71 vs 0.69, nonsignificant differences). The results suggest the relevance of ADC-based radiomics for prediction of response to IC in SNCs. 相似文献

Die Sklerafixation einer Kunstlinse ist bei insuffizientem Kapselapparat eine häufig gewählte Versorgung. Als nachteilig gilt das potenzielle Komplikationsprofil. Analyse des postoperativen Komplikationsprofils. In dieser monozentrischen, retrospektiven Analyse einer konsekutiven Fallserie von Patienten mit standardisierter, skleranahtfixierter Kunstlinsenimplantation (2007 bis 2017) wurden die dokumentierten Komplikationen in „dauerhaft visusbedrohend“ (Endophthalmitis, Aderhautblutung, Ablatio retinae) und „klinisch relevant, aber nicht dauerhaft visusbedrohend“ (z. B. Blutungen, Hypotonie) kategorisiert. Zudem wurde der Zeitpunkt der erstmaligen Dokumentation der Komplikationen erfasst und in 3 Zeiträume eingeordnet (0 bis 3, 4 bis 30 und ≥31 Tage). Vorliegend handelt es sich um das bislang größte publizierte Patientenkollektiv einer Studie mit Skleranahtfixierung einer Hinterkammerlinse (HKL). Es wurden 338 Augen von 338 Patienten in die Studie eingeschlossen (Frauen: 47 %), die mediane Nachbeobachtungszeit betrug 60 Tage (min.: 1 Tag, max.: 5833 Tage). In 68 % der Fälle wurden Komplikationen dokumentiert. „Dauerhaft visusbedrohende Komplikationen“ traten bei 3 % (n = 10) der Patienten auf. Als „klinisch relevante Komplikationen“ wurden ermittelt: okuläre Hypotension auf Werte ≤10 mm Hg (n = 119; 35 %), entrundete Pupille (n = 93; 28 %), Hyphäma, Iris- oder Glaskörperblutungen (n = 34; 10 %), Sekundärglaukom (n = 32; 9 %) und Iris-Capture (n = 17; 5 %); 41 % der Komplikationen traten innerhalb der ersten 3 Tage und 70 % innerhalb der ersten 30 Tage auf. Zu Revisionsoperationen kam es bei 4,5 % (n = 15) der Patienten. Obwohl bei ca. zwei Dritteln aller Eingriffe Komplikationen auftraten, war die Zahl der dauerhaft visusbedrohenden Komplikationen gering. Die Sklerafixation der Kunstlinse ist weiterhin ein vertretbarer Eingriff. 相似文献
