PRIMARY OBJECTIVES:
I. Assess the recurrence free survival (RFS) at 2 years after RPLND when RPLND is used as a first line treatment for patients with testicular seminoma and low volume (=\< 2cm) retroperitoneal disease.
SECONDARY OBJECTIVES:
I. Estimate the percent of patients, after treatment with RPLND, who can avoid external beam radiotherapy (XRT) or systemic chemotherapy (CTX) for seminoma.
II. Assess the complications associated with primary RPLND for seminoma.
OUTLINE:
Patients undergo RPLND.
After completion of study treatment, patients are followed up at 1 month, every 4 months for 1 year, every 6 months for 2 years, and then annually thereafter.
Inclusion Criteria:
- Pure seminoma after orchiectomy presenting with isolated retropreritoneal
lymphadenopathy OR stage I pure seminoma with isolated retroperitoneal relapse.
Relapse should be within 3 years
- Lymphadenopathy in the retroperitoneum: at least one lymph node 1-3 cm in greatest
dimension, no lymph node > 3 cm in greatest dimension, no more than 2 lymph nodes 1-3
cm in greatest dimension
- Axial imaging of lymphadenopathy within 6 weeks of the date of RPLND
- Retroperitoneal lymphadenopathy must be within the RPLND template
- If there is borderline lymphadenopathy, defined as the largest retroperitoneal lymph
node measuring 0.90 - 0.99 cm in the greatest dimension, an abdominal computed
tomography (CT) scan should be repeated (recommend interval of 6 - 8 weeks); the same
lymph node must demonstrate growth to >= 1.0 cm in the greatest dimension
- Biopsy is not required, though if biopsy of the retroperitoneal node(s) was obtained,
pathology must be consistent with pure seminoma
- Chest imaging (x-ray, CT or magnetic resonance imaging [MRI]) negative for metastasis
no more than 6 weeks prior to the date of RPLND
- Primary tumor excised by radical inguinal orchiectomy and pathology consistent with
pure seminoma
- Serum alpha fetoprotein (AFP) not more than 1.5 times upper limit of normal,
beta-human chorionic gonadotropin (HCG), lactate dehydrogenase (LDH) (per the local
laboratory assay) within 14 days of RPLND
- Eastern Cooperative Oncology Group (ECOG) performance status =< 1
- Ability to understand and the willingness to sign a written informed consent
- Serum coagulation studies (INR/PTT) and platelet counts suitable for surgery per
surgeon discretion.
Exclusion Criteria:
- Second primary malignancy
- History of receiving chemotherapy or radiotherapy
- 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
