Limited survival of adult human testicular tissue as ectopic xenograft
BACKGROUND: Grafting of testicular tissue into immunodeficient mice has become an interesting and promising scientific tool for the generation of gametes and the study of testicular function. This technique might potentially be used to generate sperm from patients whose testes need to be removed or are destroyed due to therapeutic intervention or as a consequence of disease. Here we explore whether adult human testicular tissue from patients with different testicular pathologies survives as xenograft. METHODS AND RESULTS: Testis tissue from adult patients with varying degrees of spermatogenesis was grafted into two strains of immunodeficient mice (severe combined immunodeficiency, Nu/Nu). Tissue with active spermatogenesis prior to grafting largely regressed. However, testicular tissue survival was better in cases where spermatogenesis was suppressed prior to grafting and occasionally spermatogonial stem cells survived. Cases with spermatogenic disruption were not corrected by the xenografting. CONCLUSION: Superior survival of the germinal epithelium and spermatogonia when spermatogenesis was suppressed prior to grafting could provide a novel strategy for germline preservation in pre-pubertal cancer patients. This approach could also be valuable to study the early stages of human spermatogenesis

Consensus paper: current state of first- and second-line therapy in advanced clear-cell renal cell carcinoma.
The therapy of advanced (clear-cell) renal cell carcinoma (RCC) has recently experienced tremendous changes. Several new treatments have been developed, with PD-1 immune-checkpoint inhibition being the backbone of therapy. Diverse immunotherapy combinations change current first-line standards. These changes also require new approaches in subsequent lines of therapy. In an expert panel, we discussed the new treatment options and how they change clinical practice. While first-line immunotherapies introduce a new level of response rates, data on second-line therapies remains poor. This scenario poses a challenge for clinicians as guideline recommendations are based on historical patient cohorts and agents may lack the appropriate label for their in guidelines recommended use. Here, we summarize relevant clinical data and consider appropriate treatment strategies
