Summary
Testis-sparing surgery may preserve fertility in young adults with metachronous bilateral testicular tumors. This approach should be considered to balance prognosis and quality of life in these rare cases.
Area of Science:
- Oncology
- Urology
- Reproductive Medicine
Background:
- Metachronous bilateral testicular tumors are rare, particularly in young adulthood.
- Treatment decisions must balance oncologic outcomes with long-term quality of life, including fertility preservation.
Purpose of the Study:
- To evaluate the role of testis-sparing surgery in a young adult with metachronous bilateral testicular tumors.
- To assess the impact on prognosis, sexual function, and fertility.
Main Methods:
- A case presentation of a 46-year-old man with bilateral testicular seminoma.
- Surgical intervention focused on testis-sparing approach for the second tumor.
- Histopathological analysis and follow-up of oncologic status, sexual function, and semen analysis.
Main Results:
- Testis-sparing surgery was performed for the second testicular tumor.
- Histopathology confirmed seminoma.
- Sexual function was preserved, but azoospermia was observed post-surgery.
Conclusions:
- Testis-sparing surgery is a viable option for young adults with metachronous bilateral testicular tumors.
- This approach may offer a favorable prognosis and potential for fertility preservation.
- Careful consideration of quality of life is essential in treatment planning.
