The purpose of this article is to assess the long-term fertility and attitudes towards fecundity in men after radical inguinal orchiectomy and radiation therapy (RT) for seminoma, and also to assess how often sperm cryopreservation is being offered to patients with seminoma prior to treatment. A retrospective review was conducted at 3 institutions (Wilford Hall Air Force Medical Center, Brooke Army Medical Center, and Fitzsimmons Army Medical Center) to identify patients who had undergone treatment of stage 1 or 2A seminoma during the period from 1975 to 1997. Seventy-three of 212 (34%) patients meeting the selection criteria of stage 1 or 2A seminoma provided information for this analysis. This was thought to be a good response rate, given that many of the patients had changed duty stations or had separated from the military by the time this study started. We performed a review of RT and tumor board records of 73 patients who were treated for testicular seminoma at selected treatment facilities from 1975 to 1997. Patients completed questionnaires and phone interviews that focused on prior fertility, the desire to father (more) children, other fertility-affecting factors (varicocele, cryptorchidism, infection, and erectile dysfunction), and incidence of physician counseling with regard to cryopreservation. All patients were asked to obtain a current semen analysis (SA). Eleven (15%) patients reported that they had tried to father children since completion of their RT. Seven of 11 (64%) successfully achieved pregnancy within a mean time of 3.5 years since RT (range: 1 month to 5 years). Of the 4 couples that were not successful, 1 had severe female factor infertility problems and a second had organic erectile dysfunction. A third had a past surgical history remarkable for vasectomy with subsequent vasectomy reversal. Nine patients provided SA. Mean sperm count and motility were 24.2 Mil/mL (range: 5-81 Mil/mL) and 63.1% (range: 30-90%), respectively (normal SA values: count = 20-250 Mil/mL, motility >50%, and volume = 1.5-5.0 mL). No patients were azoospermic. Overall mean time interval from radiation therapy was 7.9 years. Radiation dose and time since RT did not correlate with either SA results or conception. Only 16 of 73 (22%) men had been offered pretreatment sperm cryopreservation by their counseling physician. It is concluded that (1) patients who are treated for early stage seminoma by orchiectomy and RT have greater than a 50% chance of regaining normal semen parameters, and all regain at least some spermatogenesis; 2) recovery of spermatogenesis is not related to therapeutic radiation dose with the use of modern shielding and RT portals; (3) the majority of treated patients who desire children can conceive; and (4) sperm cryopreservation remains an underutilized option for seminoma patients.
本文旨在评估接受根治性腹股沟睾丸切除术及放射治疗(RT)的精原细胞瘤男性患者的长期生育能力及对生育的态度,同时评估在治疗前向精原细胞瘤患者提供精子冷冻保存的频率。在3家机构(威尔福德·霍尔空军医疗中心、布鲁克陆军医疗中心和菲茨西蒙斯陆军医疗中心)进行了一项回顾性研究,以确定在1975年至1997年期间接受1期或2A期精原细胞瘤治疗的患者。212例符合1期或2A期精原细胞瘤选择标准的患者中有73例(34%)为该分析提供了信息。考虑到在本研究开始时许多患者已更换工作地点或已退伍,认为这是一个不错的回应率。我们对1975年至1997年期间在选定治疗机构接受睾丸精原细胞瘤治疗的73例患者的放疗和肿瘤委员会记录进行了回顾。患者完成了问卷调查和电话访谈,重点关注既往生育能力、生育(更多)子女的愿望、其他影响生育的因素(精索静脉曲张、隐睾、感染和勃起功能障碍)以及医生关于冷冻保存的咨询发生率。所有患者均被要求进行一次当前精液分析(SA)。11例(15%)患者报告自放疗结束后曾尝试生育子女。其中7例(64%)在放疗后平均3.5年(范围:1个月至5年)内成功受孕。在4对未成功的夫妇中,1对存在严重的女性因素不孕问题,另1对存在器质性勃起功能障碍。第3对有输精管结扎及随后输精管复通的既往手术史。9例患者提供了精液分析结果。平均精子计数和活力分别为2420万/mL(范围:500万 - 8100万/mL)和63.1%(范围:30% - 90%)(正常精液分析值:计数 = 2000万 - 25000万/mL,活力>50%,体积 = 1.5 - 5.0 mL)。无患者无精子症。放疗后的总体平均时间间隔为7.9年。放疗剂量和放疗后的时间与精液分析结果或受孕均无相关性。73例男性中只有16例(22%)在治疗前被咨询医生提供了精子冷冻保存。结论为:(1)通过睾丸切除术和放疗治疗早期精原细胞瘤的患者恢复正常精液参数的机会大于50%,且均至少恢复了一些精子发生;(2)使用现代屏蔽和放疗野,精子发生的恢复与治疗性放疗剂量无关;(3)大多数有生育愿望的接受治疗患者能够受孕;(4)精子冷冻保存仍是精原细胞瘤患者未充分利用的选择。
