Journal ArticleDOI
Complete lymph node dissection versus no dissection in patients with sentinel lymph node biopsy positive melanoma (DeCOG-SLT): a multicentre, randomised, phase 3 trial
Ulrike Leiter,Rudolf Stadler,Cornelia Mauch,Werner Hohenberger,Norbert H. Brockmeyer,Carola Berking,Cord Sunderkötter,Martin Kaatz,Klaus-Werner Schulte,Percy Lehmann,Thomas Vogt,Jens Ulrich,Rudolf A. Herbst,Wolfgang Gehring,Jan-Christoph Simon,Ulrike Keim,Peter Martus,Claus Garbe +17 more
TL;DR: Results showed no difference in survival in patients treated with complete lymph node dissection compared with observation only, and complete lymph nodes dissection should not be recommended in patients with melanoma with lymph node micrometastases of at least a diameter of 1 mm or smaller.
Journal ArticleDOI
The registry of the German Network for Systemic Scleroderma: frequency of disease subsets and patterns of organ involvement.

TL;DR: In this nationwide register, a descriptive classification of patients with disease manifestations characteristic of SSc in five groups allows to include a broader spectrum of Patients with features of S sc to improve the detection and follow-up of patients presenting with different disease manifestations.
Journal ArticleDOI
Lupus erythematosus tumidus--a neglected subset of cutaneous Lupus erythematosus: report of 40 cases.
Annegret Kuhn,Dagmar Richter-Hintz,Claudia Oslislo,Thomas Ruzicka,Mosaad Megahed,Percy Lehmann +5 more
TL;DR: The clinical picture, extreme photosensitivity, histological findings, and effective treatment with antimalarials are so characteristic that LET should be considered as a separate entity and differentiated from other variants of cutaneous LE.
Journal ArticleDOI
Frequency of disease-associated and other nuclear autoantibodies in patients of the German Network for Systemic Scleroderma: correlation with characteristic clinical features.

TL;DR: This study shows that five autoantigens (that is, centromere, topoisomerase I, PM-Scl, U1-RNP and RNAP) detected more than 95% of the known SSc-associated antibody responses in ANA-positive SSc patients and characterise around 79% of all S sc patients in a central European cohort.
Journal ArticleDOI
Final Analysis of DeCOG-SLT Trial: No Survival Benefit for Complete Lymph Node Dissection in Patients With Melanoma With Positive Sentinel Node

TL;DR: The final results of the German Dermatologic Cooperative Oncology Group trial with a median follow up of 72 months showed higher event rates, but similar HRs compared with those at the 3-year analysis, confirming that immediate CLND in SLN-positive patients is not superior to observation in terms of DMFS, RFS, or OS.
