Retroperitoneal Lymph Node Dissection in Treating Patients With Testicular Seminoma

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
