Percentage of benign, malignant testicular tumours, testicular intraepithelial neoplasia (TIN) and multifocality in the neighbouring testis tissue due to a tumour cutoff size of 1.5 cm (Group A: tumor size ≤1.5 cm; Group B: tumour size 1.6–3.0 cm). P values for detecting benign and malignant testicular mass lesions between groups include Group A vs. Group B, p=0.000. P values for detecting TIN between groups include Group A vs. Group B, p=0.069. P values for detecting multifocality between groups include Group A vs. Group B, p=0.012.
