PURPOSE: We evaluated possible factors predicting testicular cancer in patients undergoing testis sparing surgery. MATERIALS AND METHODS: We retrospectively analyzed the records of all patients who underwent testis sparing surgery for a small testicular mass at a total of 5 centers. All patients with 1 solitary lesion 2 cm or less on preoperative ultrasound were enrolled in the study. Testis sparing surgery consisted of tumor enucleation for frozen section examination. Immediate radical orchiectomy was performed in all cases of malignancy at frozen section examination but otherwise the testes were spared. Univariate and multivariate analysis were performed and ROC curves were produced to evaluate preoperative factors predicting testicular cancer. RESULTS: Overall 147 patients were included in the study. No patient had elevated serum tumor markers. Overall 21 of the 147 men (14%) presented with testicular cancer. On multivariate analysis the preoperative ultrasound diameter of the lesion was a predictor of malignancy (OR 6.62, 95% CI 2.26-19.39, p=0.01). On ROC analysis lesion diameter had an AUC of 0.75 (95% CI 0.63-0.86, p=0.01) to predict testicular cancer. At the best cutoff of 0.85 the diameter of the lesion had 81% sensitivity, 58% specificity, 24% positive predictive value and 95% negative predictive value. CONCLUSIONS: Our study confirms that small testicular masses are often benign and do not always require radical orchiectomy. Preoperative ultrasound can assess lesion size and the smaller the nodule, the less likely that it is malignant. Therefore, we suggest a stepwise approach to small testicular masses, including tumorectomy, frozen section examination and radical orchiectomy or testis sparing surgery according to frozen section examination results.

Abstract

PURPOSE: We evaluated possible factors predicting testicular cancer in patients undergoing testis sparing surgery. MATERIALS AND METHODS: We retrospectively analyzed the records of all patients who underwent testis sparing surgery for a small testicular mass at a total of 5 centers. All patients with 1 solitary lesion 2 cm or less on preoperative ultrasound were enrolled in the study. Testis sparing surgery consisted of tumor enucleation for frozen section examination. Immediate radical orchiectomy was performed in all cases of malignancy at frozen section examination but otherwise the testes were spared. Univariate and multivariate analysis were performed and ROC curves were produced to evaluate preoperative factors predicting testicular cancer. RESULTS: Overall 147 patients were included in the study. No patient had elevated serum tumor markers. Overall 21 of the 147 men (14%) presented with testicular cancer. On multivariate analysis the preoperative ultrasound diameter of the lesion was a predictor of malignancy (OR 6.62, 95% CI 2.26-19.39, p=0.01). On ROC analysis lesion diameter had an AUC of 0.75 (95% CI 0.63-0.86, p=0.01) to predict testicular cancer. At the best cutoff of 0.85 the diameter of the lesion had 81% sensitivity, 58% specificity, 24% positive predictive value and 95% negative predictive value. CONCLUSIONS: Our study confirms that small testicular masses are often benign and do not always require radical orchiectomy. Preoperative ultrasound can assess lesion size and the smaller the nodule, the less likely that it is malignant. Therefore, we suggest a stepwise approach to small testicular masses, including tumorectomy, frozen section examination and radical orchiectomy or testis sparing surgery according to frozen section examination results.
