卵巢恶性生殖细胞肿瘤年轻患者保留生育功能手术后化疗对卵巢功能的影响

目的 探讨卵巢恶性生殖细胞肿瘤年轻患者行保留生育功能手术后化疗对卵巢功能的影响.方法 观察15例11～29岁施行保留生育功能手术并进行化疗的恶性卵巢生殖细胞肿瘤患者化疗阶段至化疗结束后1年期间月经改变、血清性激素水平及卵巢窦卵泡(F0)数量.并比较化疗相关性停经(CRA)患者与同期相同年龄段切除一侧附件的良性肿瘤患者(对照组10例)的血清性激素水平及卵巢窦卵泡数量.结果 15例保留生育功能手术后化疗的患者13例(13/15,86.67%)出现以月经量减少为表现的月经异常,其中10例(10/15,66.67%)于化疗第4～6疗程出现化疗相关性停经:高促性腺激素,雌二醇(E2)、窦卵泡数量显著减低.并且随着化疗的进程,停经患者增加(r=1.000,P=0.01).患者一般在化疗结束后2～3个月可恢复月经.CRA患者化疗结束后6个月Fo为(3.8±1.04)个,血清促卵泡生成素(FSH)为(8.30±1.46)mU/ml,E2为(80.50±7.86)ng/L,Fo低于对照组,FSH、E2高于对照组,差异均有统计学意义(t值分别为:7.660、5.277、7.225、P<0.001、P<0.001、P<0.001).化疗结束后1年,CRA患者激素水平及卵巢储备FSH=(5.59±0.52)mU/ml、LH=(5.25±0.84)mU/ml、E2=(56.50±5.13)ng/L、F0=(6.50±1.08)个1与对照组FSH=(5.43±0.35)mU/ml、LH:(5.17±0.48)mU/ml、E2=(58.10±3.73)ng/L、F0=(6.60±0.97)个]相当(t值分别为:1.177、0.694、0.740、0.318;P>0.05、P>O.05、P>0.05;P>0.05).结论 化疗可致保留生育功能手术后的青春期及生育年龄患者卵巢功能损害.化疗所致的停经是可逆的,但恢复月经并不等于卵巢功能恢复正常,化疗对卵巢功能损害的影响可延续到化疗结束6个月后.时该患者在化疗期间应当考虑应用保护卵巢功能的药物.

Effect of chemotherapy on ovarian function in young patients with malignant germ cell tumors of the ovary after conservative surgery

Objective To investigate the effect of chemotherapy on ovarian function in young patients with malignant germ cell tumors of the ovary after conservative surgery.Methods 15 patients (11～29 years old) with ovarian malignant germ cell tumors were treated by ovarectomy and the following chemotherapy.Their menstruation and serum follicle-stimulating hormone(FSH),luteinizing hormone(LH),estradiol(E2) levels and basal antral follicle(F0) numbers were observed from the duration of chemotherapy to one year after chemotherapy.The serum levels of FSH,LH,E2 and basal antral follicle numbers between the chemotherapy-related amenorrhea(CRA) patients and the patients with benign tumors of ovary who underwent unilateral adnexa removed at the same period(control group,n=10) were compared.Results Oligomenstruation occurred in 13 of 15 cases undergoing chemotherapy after conservative surgery(86.7%),in whom CRA occurred in 10 cases(66.7%) at the duration of 4-6 cycle chemotherapy appearing significantly rising serum level of FSH,LH and declining serum E2 level and F0 numbers.There was a significantly positive correlation between the frequency of amenorrhea and the duration of chemotherapy(r=1.000,P=0.01).Generally menstruation resumed around 2～3 months after chemotherapy.Ahhough the serum levels of sexual hormone seemed to be normal at half a year after chemotherapy in CRA patients,the serum FSH(8.30±1.46 mU/ml) and E2(80.50±7.86 ng/L) level were significantly increased as compared with that of the control group and the reverse was found in Fo numbers(3.80±1.04) (t Fo,FsH,E2=7.660,5.277,7.225;P F0,FSH,E2<0.001,<0.001,<0.001).One year after chemotherapy,serum hormone level and the ovary reserve function of the CRA patient came to be normalFSH=(5.59±0.52)mU/ml,LH=(5.25±0.84)mU/ml,E2=(56.50±5.13)ng/L,Fo=(6.50±1.08)] and that of control group FSH=(5.43±0.35)mU/ml,LH=(5.17±0.48)mU/ml,E2=(58.10±3.73)ng/L,F0=(6.60±0.97)](t=1.177,0.694,0.505,0.740;P>0.05,>0.05,>0.05,P>0.05).Conclusions Ovarian function impairment may occur in young patients in adolescence and sexual maturity period with ovarian malignant germ cell tumors who were treated by conservative surgery followed by chemotherapy.Although the CRA is reversible,the recovery of menstruation does not meail the recovery of ovarian funetion.because the ovarian impairment may continue to a duration of half a year after chemotherapy.The drug which can safeguard ovariall function should be considered during chemotherapy.
