In univariate analysis, patients with grade III–V complications showed a longer operating time (371.8 ± 124.9 vs. 319.8 ± 115.9 min.; p < 0.02), more blood transfusions (4.8 ± 5.6 vs. 1.9 ± 3.4; p < 0.001), a high number of prior chemotherapy cycles (≥ 4 cycles: 77% vs. 47%; p = 0.002), more frequent salvage RPLND (37% vs. 12%; p < 0.001), AFP elevation preoperatively (37% vs. 10%, p < 0.001), and detection of nonseminoma or immature teratoma in the RPLND specimen (43% vs. 20%; p = 0.003) (Table 2). The gene discussed is AFP; the disease is teratoma.
