Overview
This study evaluates the accuracy of blood-based biomarker testing to predict the presence of active testicular cancer.
Description
PRIMARY OBJECTIVE:
I. To measure the accuracy of the blood-based biomarker miRNA-371 to predict pre-operatively the presence of active germ cell malignancy.
OUTLINE: This is an observational study.
Patients undergo blood sample collection during screening and throughout the study. Patients whose screening blood samples show elevated miRNA-371 proceed to standard RPLND surgery. Patients whose screening blood samples show normal levels of miRNA-371 undergo standard surveillance followed by standard RPLND surgery at the time of elevated miRNA-371 levels. Patients may also have their medical records reviewed.
Eligibility
Inclusion Criteria:
- Primary tumor excised by radical inguinal orchiectomy and pathology consistent with GCT (seminoma or NSGCT)
- Clinical stage of patient is either:
- Stage I pure seminoma OR stage I pure seminoma with isolated retroperitoneal relapse or Stage IIA/B pure seminoma
- Stage I NSGCT OR stage I NSGCT with isolated retroperitoneal relapse or Stage IIA/B NSGCT
- For subjects with retroperitoneal lymphadenopathy: no lymph node \>3 cm in greatest dimension with no more than 2 nodes enlarged
- Axial abdominal/pelvic imaging (CT or MRI) and chest imaging (x-ray, CT or MRI) within 3 months of enrollment if stage I patient
- Axial abdominal/pelvic imaging (CT or MRI) and chest imaging (x-ray, CT or MRI) within 8 weeks of enrollment if stage II patient
- miRNA-371 can be drawn and sent for analysis at time of consent
- Enrollment within 1 year after orchiectomy for stage I patients
- Enrollment at any timepoint after orchiectomy for stage II patients
- Retroperitoneal lymphadenopathy must be within an RPLND template
- Biopsy of lymph node is not required, though if biopsy of the retroperitoneal node(s) was obtained, pathology must be consistent with GCT
- Serum Alpha Feto Protein (AFP) \<50 ng/ml, β-Human Chorionic Gonadotropin (β-HCG) 25 mIU/ml within 42 days (6 weeks) of enrollment
- Age ≥ 18 years
- Ability to understand and the willingness to sign a written informed consent
Exclusion Criteria:
- Second primary malignancy
- Patients receiving any other investigational agent (s)
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
