背景與目的：年輕乳腺癌患者應(yīng)用促黃體生成素釋放激素類似物戈舍瑞林治療沒有個體化用藥方案，并缺乏臨床可用的指導(dǎo)依據(jù)。該研究皆在探討抗米勒管激素(anti-Müllerian hormone，AMH)在年輕乳腺癌患者卵巢功能抑制個體化治療的評價作用。方法：選取2012年5月—2014年1月在上海交通大學附屬仁濟醫(yī)院因雌激素受體(estrogen receptor，ER)和孕激素受體(progesterone receptor，PR)陽性的乳腺癌41例患者，術(shù)前隨機分為戈舍瑞林6個療程+化療組(簡稱戈舍瑞林組)20例，化療組21例，30例同年齡組健康婦女為正常對照組，隨訪(17.4±6.2)個月。觀察兩組治療后的停經(jīng)時間與復(fù)潮時間，于術(shù)前1個月、戈舍瑞林組或化療組術(shù)后月經(jīng)復(fù)潮后3、6個月檢測AMH、促卵泡激素(follicle-stimulating hormone，F(xiàn)SH)和E2水平。正常對照組在相應(yīng)時間段內(nèi)檢測AMH、FSH和E2水平。結(jié)果：3組患者的術(shù)前臨床資料及術(shù)前FSH、E2水平差異均無統(tǒng)計學意義(P>0.05)，乳腺癌患者術(shù)前AMH水平較正常對照組降低，差異有統(tǒng)計學意義(P=0.04)；戈舍瑞林組較化療組停經(jīng)時間更短，差異有統(tǒng)計學意義(P=0.00)；戈舍瑞林組較化療組復(fù)潮時間更短，差異有統(tǒng)計學意義(P=0.00)；與正常對照組及術(shù)前比較，戈舍瑞林組及化療組FSH、E2水平在5個測定時間的差異均無統(tǒng)計學意義(P>0.05)；戈舍瑞林組及化療組在5個測定時間的AMH水平均顯著降低，差異均有統(tǒng)計學意義(P=0.00)，兩組在復(fù)潮后3、6個月AMH水平逐漸上升，差異均有統(tǒng)計學意義(P<0.05)；與化療組相比，戈舍瑞林組的AMH水平下降明顯，戈舍瑞林組的AMH水平在復(fù)潮6個月后比化療組升高，差異均有統(tǒng)計學意義(P<0.05)。結(jié)論：年輕乳腺患者在卵巢功能抑制治療+化療過程中，AMH較其他評價卵巢儲備的指標明顯下降，在其他指標恢復(fù)術(shù)前水平后仍提示卵巢受損，提示AMH可以作為評價年輕乳腺癌患者卵巢功能的指標，亦有可能成為戈舍瑞林個體化治療的評價指標。

抗米勒管激素；戈舍瑞林；年輕乳腺癌患者；卵巢功能抑制

根據(jù)美國癌癥研究所1975—2006年的流行病學統(tǒng)計，約2%的乳腺癌患者發(fā)生在20～34歲，約11%的患者發(fā)生在35～44歲［1］，研究表明化療可導(dǎo)致年輕乳腺癌患者卵巢儲備下降及卵巢早衰［2-6］。年輕乳腺癌患者推薦年卵巢功能抑制治療(ovarian function suppression，OFS)已達成國際共識，即應(yīng)用一種促黃體激素釋放激素類似物戈舍瑞林治療，可有效保護年輕患者的卵巢功能，不影響化療效果［7］，戈舍瑞林治療建立在個體化治療上［8］。但目前對年輕乳腺癌患者戈舍瑞林治療沒有個體化用藥方案，并缺乏臨床可用的指導(dǎo)依據(jù)。血清抗米勒管激素(anti-Müllerian hormone，AMH)水平與卵巢卵泡數(shù)具有相關(guān)性，近年來成為優(yōu)于年齡、促卵泡激素(follicle-stimulating hormone，F(xiàn)SH)和抑制素B等反映卵巢儲備的良好指標［9-11］。本文研究雌激素受體(estrogen receptor，ER)和孕激素受體(progesterone receptor，PR)陽性的年輕乳腺癌患者術(shù)后應(yīng)用戈舍瑞林+化療或化療，探討AMH在年輕乳腺癌戈舍瑞林個體化用藥方案的評價作用。

3 討 論

越來越多的年輕乳腺癌患者在考慮癌癥治療、保留生育能力及生存質(zhì)量的問題，針對年輕乳腺癌患者戈舍瑞林治療的個體化在臨床工作中顯得尤為重要。去年國際乳腺癌聯(lián)盟建議年輕乳腺癌患者卵巢功能抑制治療5年［8］。一項回顧性的戈舍瑞林用于絕經(jīng)前乳腺癌患者治療的成本效益分析表明，接受戈舍瑞林治療較長之間的患者生存期較長［(122.5±6.3)個月 vs (112.2±6.7)個月］，比化療獲得更好生存率及生存質(zhì)量，并且有更好的成本效益［12］。關(guān)于放化療后保留生育功能的癌癥患者在輔助生殖技術(shù)結(jié)局中的研究表明，激素受體陽性的乳腺癌患者，接受卵細胞體外成熟后體外受精-胚胎移植獲卵數(shù)及AMH水平均較低，差異有統(tǒng)計學意義(P=0.000 7)［9］。

生育期女性的AMH主要由次級卵泡、竇前和竇狀卵泡顆粒細胞產(chǎn)生［13］，卵泡發(fā)育到4～6 mm后分泌AMH，到竇前及小竇卵泡期達到高峰，隨著卵泡發(fā)育其表達水平逐漸降低［14］，AMH水平與卵巢卵泡數(shù)目具有相關(guān)性。AMH在正常周期女性血中波動很小，不受周期影響［15-16］。近年AMH成為優(yōu)于年齡、FSH和抑制素B等反映卵巢儲備的良好指標。有學者對147例生育期的晚期乳腺癌患者臨床研究表明，AMH、FSH和抑制素B能夠預(yù)測卵巢儲備功能的下降，AMH能更早、更準確地反映卵巢儲備功能的下降，不受外源激素的影響［4］，并且成為評價乳腺癌患者卵巢儲備的指標［17-18］。Su等［19］研究表明，在均衡了年齡、身體質(zhì)量指數(shù)、妊娠、種族、月經(jīng)模式和吸煙等因素，年輕乳腺癌患者的平均血清AMH水平和健康對照組差異無統(tǒng)計學意義(0.85 ng/mL vs 0.76 ng/mL，P=0.06)。本研究比較了年輕乳腺癌患者接受戈舍瑞林+化療或化療及正常生育期婦女的5個不同時間段AMH、E2和FSH的血清水平，以及戈舍瑞林+化療或化療后閉經(jīng)情況及月經(jīng)恢復(fù)時間。結(jié)果表明，兩組年輕乳腺癌患者術(shù)前AMH水平均低于正常對照組(P均<0.05)，與Su等［19］的研究結(jié)果不同，可能與樣本量較小有關(guān)。戈舍瑞林組在應(yīng)用戈舍瑞林+化療6次后AMH水平顯著低于化療組及正常對照組(P<0.05)，戈舍瑞林組在停用戈舍瑞林+化療月經(jīng)復(fù)潮3個月后AMH水平逐漸恢復(fù)(P<0.05)，6個月后AMH水平顯著高于化療組(P<0.05)。兩組應(yīng)用戈舍瑞林+化療或化療6個療程、月經(jīng)復(fù)潮6個月后戈舍瑞林組與化療組在2個測量時間FSH、E2水平上差異有統(tǒng)計學意義(P<0.05)。戈舍瑞林組使用戈舍瑞林后的閉經(jīng)時間顯著低于化療組，療程結(jié)束后月經(jīng)規(guī)律率高于化療組，復(fù)潮時間顯著低于化療組。本研究結(jié)果表明，戈舍瑞林可以保護年青乳腺腺癌患者的卵巢功能，AMH可以作為評價年輕卵巢癌患者的卵巢功能的指標，亦有可能成為OFS個體化治療的評價指標。

年輕乳腺癌患者在考慮保留生育能力和提高生活質(zhì)量方面的目的不同，未生育年輕乳腺癌患者在完成乳腺癌常規(guī)治療后，應(yīng)用戈舍瑞林和內(nèi)分泌治療多久可以妊娠，已生育的年輕乳腺癌患者如何能在生存期內(nèi)有較高的生存質(zhì)量，目前在臨床工作中缺乏可用的評價指標，而且個體化治療已迫在眉睫。本研究將繼續(xù)擴大樣本量，加長隨訪時間，將會得到一個更科學的結(jié)論。

Background and purpose:The young breast cancer patients were treated with goserelin without individualized regimen, and lack of available clinical marker. The aim of this study was to investigate the role of anti-Müllerian hormone (AMH) in evaluation of individualized treatment of ovarian function suppression in the young breastcancer patients.Methods:Forty-one young patients with estrogen receptor (ER) and progesterone receptor (PR) positive breast cancer from May 2012 to Jan. 2014 were randomly divided into 2 groups to undergo radical resection of breast cancer. According to postoperative treatment, one group was treated with goserelin + chemotherapy (n=20), and the other group received chemotherapy alone (n=21). Thirty female patients in the same age group were selected as normal control group. The time of menopause and menstrual recovery after the goserelin + chemotherapy or chemotherapy alone were observed in 2 groups. In early follicular phase (day 3-5) of the cycle preceding the operation and 3, 6 courses after the goserelin + chemotherapy treatment or chemotherapy treatment, serum levels of AMH, FSH and E2were measured in 2 groups. Accordingly, serum levels of AMH, FSH and E2were evaluated as well in normal control group.Results:There were no significant differences in preoperative general conditions and preoperative serum FSH and E2levels among the 3 groups (P>0.05). Compared with normal control group, the preoperative serum AMH levels of young breast cancer patients were decreased significantly (P=0.04). The menopause time and menstrual recovery time in 2 chemotherapy groups were significantly shorter than that in normal control group (P=0.00). Compared with normal control group and preoperative measurement, the differences in serum FSH and E2levels were not statistically significant in goserelin + chemotherapy group or chemotherapy alone group (P<0.05). The serum AMH levels measured at different time points of the goserelin + chemotherapy group and chemotherapy alone group were decreased significantly (P<0.05). Compared with the chemotherapy group, the serum AMH levels of the goserelin + chemotherapy group after 6 courses were significantly decreased, and then significantly increased 6 months after menstrual recovery (P<0.05).Conclusion:This study demonstrated that the serum AMH levels were obviously decreased after the ovarian function suppression treatment and increased after the menstrual recovery compared with evaluation of other ovarian reserve index. The serum AMH level could suggest ovarian reserve damage even after ovarian function has recovered to the noticeable level. Thus, AMH could be used clinically to evaluate the ovarian reserve of breast cancer patients as a potential marker for the individualized ovarian function suppression treatment in young breast cancer patients.
