AFP and teratoma: In binary logistic regression, the following parameters were significant in univariate analysis for grade III–V complications: high blood transfusion (OR 2.4 (1.1–5.4); p = 0.03), ≥ 4 cycles of prior chemotherapy (OR 3.7 (1.5–8.9); p = 0.004), nonseminoma or immature teratoma in the RPLND specimen (OR 3.1 (1.4–6.6); p = 0.005), salvage RPLND (OR 4.1 (1.8–9.3); p < 0.001), and AFP elevation preoperatively (OR 5 (2.2–11.7); p < 0.001).
