Akutte ændringer i endotelfunktion hos kimcelletumorpatienter behandlet med cisplatin og ubehandlede kimcelletumorkontroller
En pilotundersøgelse, der måler akutte ændringer i endotelfunktion hos kimcelletumorpatienter behandlet med cisplatin og ubehandlede kimcelletumorkontroller
Cisplatin is one of the most common chemotherapy drugs used to treat many different cancers, including germ cell tumors (GCT). Cisplatin is very effective in treating GCT, but there are side effects. One of the possible long-term side effects of cisplatin is thought to be heart disease. The way that cisplatin causes heart disease is not well understood. One possibility is that cisplatin may damage the inside layer of blood vessels called the endothelium. The purpose of this study is to measure changes in the endothelium that happen when patients with GCT get cisplatin chemotherapy and to compare these changes with a group of patients not receiving chemotherapy.

Studiebefolkning
The Cisplatin-Based Chemotherapy Group will be recruited from the Genitourinary (GU) oncology clinics. The GU Oncology section has a large clinical service which ensures adequate recruitment.
The Surgery-Only Group will consist of patients with a diagnosis of GCT who have recently had surgical management of their disease and are not planned to receive radiation or chemotherapy. Potentially eligible patients will be recruited from the GU Oncology and Urology clinics since they are seen by both services.

Cisplatin-Based Chemotherapy Group
GCT patients who are planned to start cisplatin-based chemotherapy will be identified within the genitourinary oncology service clinics and offered inclusion in the trial. |
Endo-PAT2000 testing is done six times during the study. Baseline Assessment Time 1 Cycle 1, Day 1 (Pre-chemotherapy)Time 2 Cycle 1, Day 1 (After 1st dose of cisplatin), Time 3 Cycle 1, Day 2 (Before second cisplatin dose of cycle 1), Time 4 Cycle 1, Day 5 (After last cisplatin dose of cycle 1), End-of-Study Assessment Time 5 (14-34 weeks from Time 1; e.g., 1-12 weeks following completion of the last cycle of first-line chemotherapy) Long-Term Follow Up Assessment Time 6 (24-30 months from Time 1) Time 1: A baseline assessment will be performed in the fasting state including Endo-PAT2000, vital signs, waist circumference, fasting blood draw, & urine sample. This will be considered Day 1 of the study for this group of patients. Time 2 (2-5 hours from Time 1): Two to five hours after Time 1, patients will undergo assessment of blood pressure & heart rate, including orthostatics & Endo-PAT2000 testing. Time 5 -- End of Study visit (14-34 weeks from Time 1): At a time point 14 to 34 weeks later than Time 1 patients will undergo study testing in the fasting state. This includes Endo-PAT2000 testing, vital signs including orthostatics, waist circumference, fasting blood draw, & urine sample. The Surgery-Only Group will not have any assessment at Time 3 (Day 2) or Time 4 (Day 5) due to logistical concerns. Long-Term Follow Up Assessment Time 6 (24-30 months following Time 1)

Surgery-Only Group
GCT patients who have been treated with surgery and who do not require chemotherapy or radiation will be used as a comparison group to confirm that there is not a significant change in endothelial function among GCT patients treated with surgery alone. |
