Simple blood test could spot hidden germ cell cancer
NCT ID NCT07401316
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing whether a blood test that looks for tumor DNA can find leftover cancer cells in people with germ cell tumors (a type of testicular or ovarian cancer). Researchers will enroll 130 patients with stage I, II, or III disease and check how well the test works after treatment. The goal is to develop a tool to detect cancer early and improve follow-up care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- blood test for circulating tumor DNA (ctDNA)
- What this could lead to
- If successful, this blood test could help doctors find leftover cancer cells after treatment, potentially guiding further care.
- What could go wrong
- This is an early-stage study with only 130 participants, so results may not apply to all patients. The test may not be accurate enough for routine use.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. ≥ 18 years old at the time of informed consent 2. Ability to provide written informed consent and HIPAA authorization 3. Subjects must have histologically or serologically confirmed seminomatous or non seminomatous germ cell tumor. Non-seminoma includes embryonal carcinoma, choriocarcinoma, yolk sac tumor, or teratoma. Note: Cohort I is for high-risk clinical stage I disease (high risk will be defined as per enrolling investigator discretion). Cohort II is for clinical stage II. Cohort III is for clinical stage III or IS. 4. Archival tissue for germ-cell tumor diagnosis available Exclusion Criteria: 1. Concurrent disease or condition that would make the subject inappropriate for study participation 2. Any serious medical disorder that would interfere with the subject's safety 3. Dementia, altered mental status, or any psychiatric condition that would prohibit the understanding or rendering of informed consent per treating physician coverage. 4. Patient is being tested for minimal residual disease with other experimental platforms
