简要总结
Cisplatin-combination chemotherapy causes inevitably DNA damage by platinum-DNA adduct formation of both tumor cells but also healthy cells. It therefore stands to reason that testicular cancer treatment causes an increased burden of senescent cells, which causes upregulation of the SASP resulting in a pro-inflammatory phenotype. The investigators hypothesize that this may be an important mechanism behind development of late effects and an early ageing phenotype after treatment for testicular cancer.

研究组 & 干预措施
Cross-sectional study:
Testicular cancer survivors who were treated between 2000 and 2005 or between 2006 and 2012 with cisplatin-combination chemotherapy and who were extensively phenotypically mapped within two longitudinal trials (15,16) will be invited to participate in a single cross-sectional follow-up study visit 5-20 years after chemotherapy.
干预措施: Skin biopsy (Diagnostic Test)

干预措施: Subcutaneous fat biopsy (Diagnostic Test)
Longitudinal study - chemotherapy group
Patients with metastasized testicular cancer who are about to start with cisplatin-combination chemotherapy will be invited in the longitudinal part of this study. Study participation involves four study visits:
Visit 1: before start of chemotherapy Visit 2:before third cycle of chemotherapy Visit 3: one month after completion of chemotherapy Visit 4: one year after start of chemotherapy
干预措施: Skin biopsy (Diagnostic Test)
