Objectives:
To evaluate retrospectively the indications, surgical technique, feasibility, and follow-up data of our frozen section analysis-guided organ-sparing approach to small testicular tumors. Removal of a solitary testis or bilateral orchiectomy for testicular neoplasm results in androgen deprivation and infertility. Moreover, removal of a testis for benign lesions is to be avoided. Organ-sparing surgery aims at preserving enough testicular parenchyma to maintain physiologic endocrine function and, if possible, fertility.
Methods:
Tumors of 25 mm or less in diameter were managed by an organ-sparing approach. Normal preoperative plasma levels of luteinizing hormone and testosterone were a prerequisite. After localization of the tumor by ultrasonography and accurate staging, organ-sparing surgery was performed under cold ischemia. Frozen section analyses of the tumor and tumor bed biopsies were obtained. In the case of malignant germ cell tumor with a normal contralateral testis, ablation of the tumor-bearing testis was performed.
Results:
A total of 32 organ-preserving procedures were performed in 30 patients without any complications. Local recurrence was observed in 1 patient who refused to undergo local radiotherapy for concomitant testicular intraepithelial neoplasia; repeat organ-sparing surgery was performed in this patient. After organ-sparing surgery, ablation of the remaining testis was performed in 1 patient because of positive margins on final histologic analysis and in another patient because of endocrine insufficiency. In all other patients, the serum testosterone levels remained within normal limits. No retroperitoneal, pulmonary, or other recurrences were encountered; all patients were free of disease at a mean follow-up of 46.3 months.
Conclusions:
The organ-sparing frozen section analysis-guided approach to testicular masses represents a promising treatment alternative to orchiectomy in selected patients with bilateral malignant testicular tumors, tumors in a solitary testis, or unilateral or bilateral benign tumors. The technique is oncologically efficient, lifelong hormonal substitution can be prevented, and, in some patients, even fertility may be preserved, provided certain criteria concerning patient selection and surgical technique are observed.
Insights
Organ-sparing surgery for small testicular tumors preserves endocrine function and fertility. Frozen section analysis guides this approach, offering an alternative to orchiectomy with oncological efficiency.
Area of Science:
- Urology
- Oncology
- Surgical Pathology
Background:
- Testicular tumors necessitate treatment, with orchiectomy (testis removal) potentially causing androgen deprivation and infertility.
- Organ-sparing surgery aims to preserve testicular parenchyma for endocrine and fertility functions.
- Avoiding testis removal for benign lesions is crucial.
Purpose of the Study:
- To retrospectively evaluate the indications, technique, feasibility, and follow-up of a frozen section analysis-guided organ-sparing approach for small testicular tumors.
- To assess the oncological safety and functional outcomes of this minimally invasive strategy.
Main Methods:
- Retrospective analysis of 32 organ-preserving procedures in 30 patients with tumors ≤25 mm.
- Preoperative assessment included luteinizing hormone and testosterone levels.
- Frozen section analysis guided intraoperative decisions, with cold ischemia employed.
Main Results:
- 32 procedures were performed without immediate complications.
- One local recurrence occurred, managed with repeat organ-sparing surgery.
- Two patients required testis ablation post-surgery (positive margins, endocrine insufficiency).
- Most patients maintained normal testosterone levels; no distant recurrences were observed at mean 46.3 months follow-up.
Conclusions:
- Frozen section analysis-guided organ-sparing surgery is a feasible and oncologically effective alternative to orchiectomy for selected testicular tumors.
- This approach can prevent lifelong hormonal substitution and potentially preserve fertility.
- Careful patient selection and surgical technique are essential for optimal outcomes.
