At diagnosis, approximately 90% of cases are germ cell tumours (GCT), categorised as either seminoma (55-60%) or non-seminoma types (40-45%).\n\nFor many years, the management of patients with CS IIA/B seminoma and retroperitoneal lymph node involvement ≤ 3 cm are eligible for treatment with either radiotherapy or chemotherapy Despite high cure rates for CS II seminoma (approximately 90%) with chemotherapy or radiotherapy, concerns persist regarding short and long-term treatment-related toxicities (such as increased risks of cardiovascular disease and secondary malignancies As such, an alternative strategy which has been explored in this study is the role of RPLND for the management of these patients', 'detailedDescription': 'Testicular cancer represents 1% of adult neoplasms and is the most common solid malignancy in young men. At diagnosis, approximately 90% of cases are germ cell tumours (GCT), categorised as either seminoma (55-60%) or non-seminoma types (40-45%). Approximately 20% of men with seminoma present with clinical stage (CS) II disease, characterized by enlarged retroperitoneal lymph nodes without distant metastasis.\n\nFor many decades for patients who recur following CS 1 seminoma or present with de novo CS IIA/B seminoma, either radiotherapy (30-36Gy) or chemotherapy (BEPx3, EPx4) has been the mainstay of treatment. Yet, both treatment paradigms carry significant short and long-term treatment-related toxicities. Radiotherapy, when compared to surveillance or surgery alone, has been shown to double the risk of cardiovascular disease and secondary malignancies (with an incidence of 2-3%). Additionally, patients who receive chemotherapy for GCTs can develop complications including irreversible neurotoxicity (10%), ototoxicity (5-12%), pulmonary toxicity, which may result in permanent restrictive lung disease (8%), metabolic syndrome (10-16%), and hypogonadism (4%). Additionally, patients are at an approximate 3-7-fold increase in cardiovascular mortality and a two-fold increase in secondary solid malignancies and leukaemia. Furthermore, both treatment modalities can harm fertility potential by approximately 20-30%.\n\nHowever, in the past few years, a number of prospective single arm studies have been published evaluating the role of RPLND. RPLND is an appealing choice for patients with low-volume metastatic seminoma for several reasons: Firstly, seminoma exhibits a more indolent biological behaviour and a predictable lymphatic spread pattern compared to non-seminoma diseases, potentially allowing a greater chance of cure with surgery alone. Secondly, RPLND enables precise pathological staging which can avoid overtreatment in those with pathologically negative lymph nodes. It offers an opportunity to reduce the burden of chemotherapy by reserving this treatment only for the small proportion of men who will relapse following RPLND. Finally, RPLND offers an acceptably low risk of short or long-term complications when performed at experienced centres.\n\nTherefore, our objective is to prospectively evaluate the short and long-term safety and efficacy of Primary Retroperitoneal Lymph Node Dissection (RPLND) for patients with testicular seminoma and limited retroperitoneal lymph node metastasis.'}, 'eligibilityModule': {'sex': 'MALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
