Malignant Testicular Germ Cell Tumor
Conditions
Brief summary
This study evaluates the accuracy of blood-based biomarker testing to predict the presence of active testicular cancer.
Detailed 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.
Interventions
Patients undergo blood sample collection during screening and throughout the study. Based on results, patients will undergo a primary RPLND surgery or standard surveillance. Surveillance will follow until year 5.
Patients undergo blood sample collection during screening and throughout the study. Based on results, patients will undergo a primary RPLND surgery or reassessment and then surveillance will follow until year 5.

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
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Accuracy of miRNA-371 to predict pre-operatively the presence of active germ cell malignancy | Through study completion, up to 5 years | The positive predictive value of pre-operatively elevated miRNA-371 levels in predicting active GCT will be determined by pathologic review of RPLND specimens. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The 2-year disease-free survival | Through study completion, up to 5 years | Estimate the 2-year disease-free survival for patients who are miRNA negative at enrollment |
| Persistence of positive postoperative miRNA as a predictor of relapse at follow-up | Through study completion, up to 5 years | Evaluate the relapse rate at follow-up in patients with positive postoperative miRNA after RPLND |
| Negative predictive value of negative pre-operative miRNA | Through study completion, up to 5 years | Estimate the negative predictive value of negative pre-operative miRNA as confirmed by completing 2-year surveillance or pathological confirmation (i.e. biopsy or RPLND) |
