Senescence and the Early Ageing Phenotype After Chemotherapy for Testicular Cancer: the SEA-CAT Study

January 3, 2023 updated by: J.A. Gietema, University Medical Center Groningen
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.

  • Is about to start with first-line cisplatin-based chemotherapy
  • Younger than 50 years of age at diagnosis of metastatic testicular cancer

Stage I control-group:

  • Diagnosis of testicular cancer stage I disease
  • Younger than 50 years of age at diagnosis of testicular cancer

Exclusion Criteria:

A potential subject who meets any of the following criteria will be excluded from participation in this study:

- Not able to provide informed consent (in example in case of mental or psychiatric disability)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: 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.
A 4 mm skin biopsy will be performed at the upper leg of the patient. Before the skin biopsy local anesthesia is applied subcutaneously. In these skin biopsies senescent cells will be detected by p16, p21 and yH2Ax staining. Furthermore, we will measure platinum levels in the skin biopsies.

An abdominal subcutaneous fat biopsy will be performed 7-10 cm on the right side of the umbilicus. Before the fat biopsy local anesthesia is applied subcutaneously. An amount of 30 mg fat tissue will be collected using needle aspiration.

In these fat biopsies senescent cells will be detected by p16, p21 and yH2Ax staining. Furthermore, we will measure platinum levels (ICP-MS), adipocytokines (leptin, adiponectin, interleukin-6, PAI-1, TNF-α), p53 activation indirectly by measuring p21 or mdm2 expression using immunohistochemistry, microRNA regulation of insulin signaling in adipose tissue: miR-103, miR-107, miR-29.

Experimental: 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

A 4 mm skin biopsy will be performed at the upper leg of the patient. Before the skin biopsy local anesthesia is applied subcutaneously. In these skin biopsies senescent cells will be detected by p16, p21 and yH2Ax staining. Furthermore, we will measure platinum levels in the skin biopsies.

An abdominal subcutaneous fat biopsy will be performed 7-10 cm on the right side of the umbilicus. Before the fat biopsy local anesthesia is applied subcutaneously. An amount of 30 mg fat tissue will be collected using needle aspiration.

Furthermore, we will measure platinum levels (ICP-MS), adipocytokines (leptin, adiponectin, interleukin-6, PAI-1, TNF-α), p53 activation indirectly by measuring p21 or mdm2 expression using immunohistochemistry, microRNA regulation of insulin signaling in adipose tissue: miR-103, miR-107, miR-29.

Other: Longitudinal study - stage I control group

Patients with stage I testicular cancer will serve as control group with three study visits:

Visit 1: at time of orchidectomy Visit 2: one month Visit 3: one year after orchidectomy

A 4 mm skin biopsy will be performed at the upper leg of the patient. Before the skin biopsy local anesthesia is applied subcutaneously. In these skin biopsies senescent cells will be detected by p16, p21 and yH2Ax staining. Furthermore, we will measure platinum levels in the skin biopsies.
