To evaluate the infertility rate in patients with germ cell tumors receiving chemotherapy with cisplatin, etoposide (VP-16), and bleomycin (PVP16B).
Thirty patients were evaluated. All patients had undergone chemotherapy with two to four cycles of PVP16B. A single semen analysis was performed 24 to 78 months following initiation of chemotherapy. All 30 patients were continuously disease-free. Eight of these patients had also undergone nerve-sparing retroperitoneal lymph node dissection (RPLND).
The median sperm concentration was 33.9 x 10(6), with a median volume of 3.2 mL. The median total sperm count was 86.4 x 10(6). Oligospermia (< 40 x 10(6) total sperm count) was found in 13 patients (43%), including six (20%) who were azoospermic. There was a high incidence of morphologically abnormal sperm, with only one patient having more than 50% normal spermatozoa. Only 13 patients (43%) had sperm motility greater than 50%. Five patients had positive semen antisperm immunoglobulin G (IgG). Eight patients fathered children, including three with document oligospermia.
Patients with germ cell tumors successfully treated with PVP16B chemotherapy are at substantial risk for persistent semen abnormalities. However, some patients with oligospermia will slowly recover and others are still capable of reproductive capacity despite continued oligospermia.
评估接受顺铂、依托泊苷(VP - 16)和博来霉素(PVP16B)化疗的生殖细胞肿瘤患者的不育率。
对30例患者进行评估。所有患者均接受了两到四个周期的PVP16B化疗。化疗开始后24至78个月进行了一次精液分析。所有30例患者均持续无病。其中8例患者还接受了保留神经的腹膜后淋巴结清扫术(RPLND)。
精子浓度中位数为33.9×10⁶,精液量中位数为3.2毫升。总精子数中位数为86.4×10⁶。13例患者(43%)存在少精子症(总精子数<40×10⁶),其中6例(20%)无精子症。形态异常精子的发生率很高,只有1例患者正常精子超过50%。只有13例患者(43%)的精子活力大于50%。5例患者精液抗精子免疫球蛋白G(IgG)呈阳性。8例患者育有子女,其中3例有记录的少精子症。
成功接受PVP16B化疗的生殖细胞肿瘤患者存在持续精液异常的重大风险。然而,一些少精子症患者会缓慢恢复,其他患者尽管持续少精子症仍有生殖能力。
