Due to the availability of immune checkpoint blockade (ICB) in the real-world setting, the prognosis of metastatic UM has improved. However, it is unclear how the presence of hepatic and extrahepatic metastasis impacts the response and survival after ICB. Methods: A total of 178 patients with metastatic UM treated with ICB were included in this analysis. Patients were recruited from German skin cancer centers and the German national skin cancer registry (ADOReg). To investigate the impact of hepatic metastasis, two cohorts were compared: patients with liver metastasis only (cohort A, n = 55) versus those with both liver and extra-hepatic metastasis (cohort B, n = 123). Data were analyzed in both cohorts for response to treatment, progression-free survival (PFS), and overall survival (OS). The survival and progression probabilities were calculated with the Kaplan-Meier method. Log-rank tests, χ\(^2\) tests, and t-tests were performed to detect significant differences between both cohorts. Results: The median OS of the overall population was 16 months (95\% CI 13.4-23.7) and the median PFS, 2.8 months (95\% CI 2.5-3.0). The median OS was longer in cohort B than in cohort A (18.2 vs. 6.1 months; p = 0.071). The best objective response rate to dual ICB was 13.8\% and to anti-PD-1 monotherapy 8.9\% in the entire population. Patients with liver metastases only had a lower response to dual ICB, yet without significance (cohort A 8.7\% vs. cohort B 16.7\%; p = 0.45). Adverse events (AE) occurred in 41.6\%. Severe AE were observed in 26.3\% and evenly distributed between both cohorts. Conclusion: The survival of this large cohort of patients with advanced UM was more favorable than reported in previous benchmark studies. Patients with both hepatic and extrahepatic metastasis showed more favorable survival and higher response to dual ICB than those with hepatic metastasis only.}, language = {en} } @article{KochPetzoldWesselyetal.2022, author = {Koch, Elias A.

Here, we provide hitherto the first analysis of ICB re-induction in UM. A total of 177 patients with metastatic UM treated with ICB were included from German skin cancer centers and the German national skin cancer registry (ADOReg). To investigate the impact of ICB re-induction, two cohorts were compared: patients who received at least one ICB re-induction (cohort A, n = 52) versus those who received only one treatment line of ICB (cohort B, n = 125). In cohort A, a transient benefit of overall survival (OS) was observed at 6 and 12 months after the treatment start of ICB. There was no significant difference in OS between both groups (p = 0.1) with a median OS of 16.2 months (cohort A, 95\% CI: 11.1-23.8) versus 9.4 months (cohort B, 95\% CI: 6.1-14.9). Patients receiving re-induction of ICB (cohort A) had similar response rates compared to those receiving ICB once. Re-induction of ICB may yield a clinical benefit for a small subgroup of patients even after resistance or development of toxicities.}, language = {en} } @article{HassanVasquezGuoLiangetal.2017, author = {Hassan, Musa A. and Vasquez, Juan J. and Guo-Liang, Chew and Meissner, Markus and Siegel, T.

For an obligate intracellular parasite that is shielded from the cytosolic host immune factors by a parasitophorous vacuole, the brief entry into the extracellular space is likely to exert enormous stress. Due to its role in cellular stress response, we hypothesize that translational control plays an important role in regulating gene expression in \(Toxoplasma\) during the lytic cycle. Unlike transcriptional profiles, insights into genome-wide translational profiles of \(Toxoplasma\) \(gondii\) are lacking. Methods We have performed genome-wide ribosome profiling, coupled with high throughput RNA sequencing, in intracellular and extracellular \(Toxoplasma\) \(gondii\) parasites to investigate translational control during the lytic cycle. Results Although differences in transcript abundance were mostly mirrored at the translational level, we observed significant differences in the abundance of ribosome footprints between the two parasite stages. Furthermore, our data suggest that mRNA translation in the parasite is potentially regulated by mRNA secondary structure and upstream open reading frames. Conclusion We show that most of the \(Toxoplasma\) genes that are dysregulated during the lytic cycle are translationally regulated.}, language = {en} }
