Surgical management of testicular cancer with limited retroperitoneal disease

Chemotherapy offers excellent long-term survival rates for men with clinical stage II germ cell tumours. However, in this predominantly younger population, chemotherapy is associated with long-term adverse effects. Primary retroperitoneal lymph node dissection (RPLND) may serve as an alternative treatment option, preserving oncological safety while potentially reducing adverse effects in men with limited retroperitoneal disease.

The rate of negative surgical specimens (pN0) in primary RPLND series varies between 4% and 16% in seminoma and 12-29% in nonseminoma, respectively. This suggests that early restaging, novel biomarkers, and/or percutaneous biopsies should be considered to minimize overtreatment. In stage II seminoma, three prospective RPLND series with follow-up periods ranging from 22 to 51 months report recurrence rates between 6% and 30%. In contrast, only retrospective data are available for stage II nonseminoma, with follow-up periods and recurrence rates yet to be fully defined. Following primary RPLND with confirmed viable cancer, adjuvant chemotherapy reduces recurrence risk. In cases of recurrence after primary RPLND, first-line chemotherapy remains a highly effective salvage option. Ongoing research is needed to identify risk factors for contralateral retroperitoneal disease to refine surgical templates and to determine predictors of recurrence, allowing for more personalized decisions regarding the use of adjuvant chemotherapy and follow-up strategies.

Men with clinical stage II germ cell tumours may benefit from RPLND due to its lower risk of long-term side effects. Chemotherapy is an effective salvage treatment if needed. Although RPLND is a safe and promising option, further studies are required to better understand relapse risks and to tailor treatment plans based on individual patient factors.
