Long-term follow-up using testicle-sparing surgery for Leydig cell tumor

Area of Science:

• Oncology
• Urology
• Endocrinology

Background:

• Leydig cell tumors are the most common non-germ cell testicular tumors.
• Conservative surgical treatment has been evaluated for its long-term efficacy.

Purpose of the Study:

• To perform a long-term evaluation of conservative surgical treatment for Leydig cell tumors.
• To assess the safety and feasibility of testicle-sparing surgery for Leydig cell tumors.

Main Methods:

• A multicenter retrospective study involving 22 patients treated with conservative surgery across 6 European centers.
• Data collection included physical examination, hormone assays, tumor markers, ultrasonography, radiography, and endocrinologic evaluation.
• Long-term follow-up protocols involved regular check-ups, imaging, and laboratory tests.

Main Results:

• Over a mean follow-up of 180 months, no local recurrence or metastasis was observed in any patient.
• The majority of patients (68.2%) presented with testicular nodules detected by ultrasonography.
• All patients (100%) remained alive with disease-free survival, highlighting the effectiveness of the treatment.

Conclusions:

• Early diagnosis and treatment of Leydig cell tumors lead to favorable long-term outcomes.
• Testicle-sparing surgery is a safe and feasible first-line therapeutic option for Leydig cell tumors.
• Conservative management demonstrates high disease-free survival rates, even for tumors with metastatic potential.
