Risk of Bleomycin-Related Pulmonary Toxicities and Operative Morbidity After Postchemotherapy Retroperitoneal Lymph Node Dissection in Patients With Good-Risk Germ Cell Tumors.

Abstract

Three cycles of bleomycin, etoposide, and cisplatin (BEP × 3) or four cycles of etoposide and cisplatin (EP × 4) are first-line chemotherapy regimens for men with International Germ Cell Cancer Collaborative Group (IGCCCG) good-risk germ cell tumors (GCTs). We determined whether inclusion of bleomycin affected pulmonary and operative morbidity after postchemotherapy retroperitoneal lymph node dissection (PC-RPLND). We queried our database to identify IGCCCG good-risk patients who received BEP × 3 or EP × 4 induction chemotherapy before PC-RPLND from 2006 to 2016. Patients who received combination regimens were excluded. The primary outcomes of interest were pulmonary morbidity (prolonged intubation, reintubation, supplemental oxygen use, intensive care unit stay) and operative morbidity (operative time, length of stay, concomitant procedures, estimated blood loss). We analyzed 234 patients (191 BEP × 3 v 43 EP × 4). All patients were extubated immediately after the operation. None were reintubated or discharged on oxygen. Two patients in each cohort required an intensive care unit stay for nonpulmonary reasons. Patients treated with BEP required shorter use of supplemental oxygen (0.99 v 1.63 days; P = .005). No significant differences were found in preoperative mass size ( P = .42) or concomitant surgeries ( P = .58). Operative time was significantly shorter (131 v 170 minutes; P < .01), and estimated blood loss was considerably less (194 v 226 mL; P < .01) in patients treated with BEP. Length of stay was shorter in patients treated with BEP (3.3 v 3.9 days; P < .01). In a modern surgical cohort, the inclusion of bleomycin does not seem to influence pulmonary morbidity, operative difficulty, or nonpulmonary postoperative complications after PC-RPLND in men with IGCCCG good-risk GST.
