Results and conclusions: Predictors of inguinal metastases in penile carcinoma: * Large primary tumor size (T4, 66.7%; T3, 45.2%; T2, 25.4%; T1, 7.7%; p=0.009) * High preoperative serum SCC (SCC >3ng / mL, 48.5%; SCC ≤ 3 ng / ml, 21%; p=0.009) * High grade tumor (grade 3 squamous cell carcinoma, 75%; grade 2, 52.9% and grade 1, 24.2%; p=0.017) Of them, the high preoperative serum SCC (> 3ng / mL) and the high grade tumor are the major predictors (multiple variables logistic regression; p=0.0117 and 0.0227).
