Abstract:
We report on 6 patients with bilateral testicular germ cell tumors treated by organ sparing surgery. Tumors 6 to 30 mm. in diameter were enucleated, and biopsies of the tumor bed and peripheral parenchyma were taken. Histological examination revealed seminoma in 4 cases, embryonal carcinoma in 1 and a Leydig cell tumor in 1. All patients underwent testicular radiation therapy with 20 Gy. for carcinoma in situ. A testicular biopsy was performed 6 months postoperatively to evaluate therapeutic success. Median followup was 43 months, all patients were free of disease and there was no local recurrence. Luteinizing hormone and testosterone were within the normal range and no androgen substitution was necessary. Our study suggests that organ sparing surgery for bilateral testicular germ cell tumors represents a new therapeutic approach with endocrinological and psychological advantages. In our experience conservative surgery is possible under certain prerequisites, including organ confined tumor without infiltration of the rete testis, obtaining multiple biopsies of the tumor bed and peripheral parenchyma, associated carcinoma in situ treated by radiation therapy and close followup of patients.
Insights
Organ-sparing surgery for bilateral testicular germ cell tumors is a viable new approach. This method preserves endocrine function and psychological well-being, showing promising disease-free outcomes.
Area of Science:
- Urology
- Oncology
- Endocrinology
Background:
- Bilateral testicular germ cell tumors present unique treatment challenges.
- Organ-sparing surgery is an emerging alternative to radical orchiectomy.
Purpose of the Study:
- To evaluate the efficacy and safety of organ-sparing surgery for bilateral testicular germ cell tumors.
- To assess the oncological and endocrinological outcomes of this conservative approach.
Main Methods:
- Six patients with bilateral testicular germ cell tumors underwent organ-sparing surgery with tumor enucleation.
- Histopathological analysis, testicular radiation therapy for carcinoma in situ, and postoperative biopsies were performed.
- Median follow-up was 43 months.
Main Results:
- All patients remained disease-free with no local recurrence.
- Luteinizing hormone and testosterone levels remained within normal ranges, negating the need for androgen substitution.
- Successful conservative management was achieved under specific prerequisites.
Conclusions:
- Organ-sparing surgery is a safe and effective therapeutic option for selected patients with bilateral testicular germ cell tumors.
- This approach offers significant endocrinological and psychological benefits compared to traditional treatments.
- Careful patient selection, including organ-confined tumors and comprehensive biopsies, is crucial for successful outcomes.
