Purpose: To establish the prevalence of sexual dysfunctions after different treatment modalities for nonseminomatous testicular germ cell tumor (NSTGCT) and to investigate whether treatment-induced angiopathy and neuropathy is related to sexual dysfunction.
Patients and methods: A questionnaire assessing sexual dysfunction was sent to 255 NSTGCT survivors. Polychemotherapy (PCT) regimens (cisplatin, vinblastine, and bleomycin [PVB], vinblastine substituted by etoposide [BEP], or cisplatin substituted by carboplatin [CEB], etoposide combined with cisplatin [EP], or with ifosfamide and cisplatin [VIP] were compared regarding treatment-induced angiopathy and neuropathy. Sexual dysfunctions were related to Raynaud's phenomenon and acral paresthesia.
Results: Among the 215 responders, 56 (26%) had been treated by orchidectomy and surveillance, 42 (19.6%) by PCT, and 117 (54.4%) by PCT and resection of residual retroperitoneal tumor mass (RRRTM). Overall, loss of libido was reported by 19.1%, decreased arousal by 11.2%, erectile dysfunction by 12.1%, decreased intensity of orgasm by 20%, and ejaculatory problems by 28%. Patients treated with PVB suffered more often from Raynaud's phenomenon compared with those treated with other regimens (40.4% v 29%; P < .05) and from paresthesia (31.6% v 14.7%; P < .05). Patients with Raynaud's phenomenon had more often erectile dysfunction (28.8%) compared with those without (8.4%) (P < .05).
Conclusion: Compared with orchidectomy alone, PCT, with or without RRRTM, induced more often posttreatment sexual dysfunction. Compared with other chemotherapeutic regimens, signs of angiopathy and neuropathy were most prevalent in those treated with PVB. Erectile dysfunction was related to the chemotherapy-induced Raynaud's phenomenon but not to acral paresthesia.
