Treatment Groups

This trial involves 2 different treatments. Laboratory Biomarker Analysis is the primary treatment being studied. Participants will all receive the same treatment. There is no placebo group. The treatments being tested are not being studied for commercial purposes.

Main TreatmentA portion of participants receive this new treatment to see if it outperforms the control.
Laboratory Biomarker Analysis
Retroperitoneal Lymph Node Dissection
Control TreatmentAnother portion of participants receive the standard treatment to act as a baseline.


This trial is for male patients of any age. You must have received 1 prior treatment for Seminoma or one of the other 3 conditions listed above. There are 10 eligibility criteria to participate in this trial as listed below.

Inclusion & Exclusion Checklist
Mark “yes” if the following statements are true for you:
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
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

Measurement Requirements

This trial is evaluating whether Laboratory Biomarker Analysis will improve 3 secondary outcomes in patients with Seminoma. Measurement will happen over the course of Up to 12 months.

Short-term RPLND complication rates
The rate of short and long term complications will be calculated.
Associated 95% confidence intervals will be constructed. Actuarial RFS will be calculated by the Kaplan Meier method.
Long-term RPLND complication rates
The rate of short and long term complications will be calculated.

Can seminoma be cured?

Currently proven effective radiation therapy and chemotherapy regimes for patients with low grade testicular cancer prolong disease free survival, but further research is required before these treatments can be considered definitive.

Anonymous Patient Answer

What are common treatments for seminoma?

While chemotherapy is often recommended for patients with localized/Stage I disease, other treatments may be performed in combination with chemotherapy in Stage I patients. These patients can be administered chemotherapy, radiation, or both. For tumors which are locally advanced or have spread to other areas/regions, surgery can often be the most effective treatment for most patients. For advanced Stage 2 - 3 patients, radiation + chemotherapy (such as BEP (Bemaxalan, Etoposide, and Platinol)), chemoradiation, or cisplatin-based chemotherapy-radiation combination can be given. However, patients may be given different treatments depending on their specific tumor location, where they have metastasized, and their general overall health.

How many people get seminoma a year in the United States?

In 1999, there were an estimated 20,200 men who had a diagnosis of Sertoli and Leydig cell adenoma. At least 6,900 of these cases would have been classified as seminoma, but only 50 would have been diagnosed. The majority of cases diagnosed do not meet current requirements for malignancy or suspicion of metastasis. Patients should be aware that even though they meet current clinical parameters, many of their tumors are probably non-seminoma.

What is seminoma?

Testicular cancer is most commonly diagnosed in young men 20-50 years old. This tumour is most commonly caused by spermatozoa but also sperm-associated antigen and carcinoma of Sertoli cells are suspected. The most significant disease manifestations are painful orchitis and epididymitis. Rare features are the presence of high levels of human chorionic gonadotrophin in the serum of patients with seminoma. In spite of an unfavourable prognosis, an appropriate management is always possible. Seminal fluid is a complex entity exhibiting a number of protein expressions. The protein profiles can be subdivided into a specific pattern (non-seminoma) and a non-specific one.

What are the signs of seminoma?

The hallmark of seminoma is a diffuse, nonfibroid inflammation reaction in the tunica albuginea. If ipsilateral or bilateral inguinal or para aortic lymph nodes are palpated, this suggests a possibility of metastasis from seminoma. A complete history of a history of cryptorchidism is a marker of a high-grade seminoma. For the other signs of metastasis in seminoma, further histologic confirmation may be necessary.

Anonymous Patient Answer

What causes seminoma?

Seminoma is a malignant germ cell tumor (GCT) of the testis. It rarely metastasizes. The seminoma-like lesions of the testis are associated with certain GCTs (e.g. non-seminoma GCTs [NGCT]) and therefore warrant additional clinical and radiological testing. In selected cases, they can be removed via orchiectomy.

Anonymous Patient Answer

Who should consider clinical trials for seminoma?

Clinicians are likely to consider clinical trials for patients with well-differentiated seminoma of the testis. However, clinicians should also consider eligibility criteria for clinical trials for patients with late stage disease.

Is laboratory biomarker analysis typically used in combination with any other treatments?

Recent findings indicates that PSA level measurement (through the CA 17 kDa chain) combined with other clinical and therapeutic parameters is significantly correlated with the treatment response to therapy with cotrimoxazole. Considering the current limitations in the use of only a single biomarker during treatment follow-up, the combination with cotrimoxazole is proposed as a promising method for a correct evaluation of the treatment response of patients with nonmetastatic testicular germ cell tumours.

What is the average age someone gets seminoma?

To our knowledge, this is the first analysis of the age of diagnosis for a cohort of patients with seminoma. The incidence of testicular germ cell tumors in the United States and Europe is decreasing and age-adjusted incidence rates have been dropping. The incidence of testicular germ cell tumors in Finland is lower than the reported European incidence rates. Findings from a recent study suggests a decline in the age of onset of testicular germ cell tumors in Finland, an effect of decreasing birth rates that is common in countries that allow access to reproductive technology and increasing fertility rates in the population.

Does seminoma run in families?

Findings from a recent study, one of only a handful of similar studies to study the phenomenon of "seminoma-in-families" in a case-control framework, demonstrated that the phenomenon exists.

What is laboratory biomarker analysis?

Levels of circulating S-ICP were independent predictive markers for survival following resection of NSCLC with high risk of recurrence according to the GGT/ICP (G-ICP) score. The G-ICP score can be utilized as an early predictor of survival following resection of NSCLC.
