這里是丁香園「醫(yī)周一句 · Clinical Pearls」欄目的第 24 期,今天我們要討論的是乳腺癌患者懷孕的安全性問題。
乳腺癌一直是女性癌癥的頭號殺手,近些年來乳腺癌患者日趨年輕化,甚至把魔爪伸向了許多未孕的年輕女性。
有調(diào)查研究顯示,約有 50% 以上的乳腺癌年輕女性有懷孕的意愿,但最終只有 4%~7% 的患者會付諸行動,這是為什么呢?原來,比起當(dāng)媽媽,她們更擔(dān)心懷孕會使她們的乳腺癌復(fù)發(fā)或者轉(zhuǎn)移。
為了解決這一困惑,腫瘤權(quán)威雜志 Journal of Clinical Oncology(IF:24.008)就發(fā)表過一篇文章,說懷孕不僅不會增加乳腺癌復(fù)發(fā)或轉(zhuǎn)移風(fēng)險,甚至還起到對機體一定的保護作用。
讓我們來看看原文是如何描述的:
In this study, we addressed for the ?rst time the prognostic impact of subsequent pregnancy in women with a history of an endocrine- sensitive breast cancer(BC).
The main analysis indicated that pregnancy did not seem to be protective against BC recurrence in patients with an endocrine- sensitive disease.
The DFS(Disease-free survival)analysis in the ER-positive population indicated that subsequent pregnancy is not detrimental. In addition, the pregnant group had a better OS (Overall survival) independent of ER status.
These ?ndings point out that pregnancy after BC diagnosis could be considered safe in women with history of an ER-positive disease.
這項納入 1,207 人的多中心回顧性研究表明,在乳腺癌治療后,懷孕是安全可行的,甚至懷孕還可以提高乳腺癌患者的總生存期,也不會增加雌激素受體陽性的乳腺癌患者(乳腺癌的一種類別)復(fù)發(fā)轉(zhuǎn)移的風(fēng)險。
然而,這項發(fā)表于 2013 年的研究報道,由于對于妊娠的乳腺癌患者隨訪時間較短,且對雌激素受體陰性的乳腺癌患者懷孕風(fēng)險未進行闡明,為了讓這一結(jié)果更具說服力,該團隊在 2017 年做了后續(xù)補充報道:
There was no OS difference between the 2 cohorts in pts with ER BC, but a significant improved OS was observed in the pregnant cohort for ER-pts yielding a significant overall estimate. Long-term follow-up confirms that pregnancy is safe and should not be discouraged irrespective of ER status.
也就是說,通過長期隨訪觀察,不管是雌激素受體陽性還是陰性,懷孕均不會影響乳腺癌患者的生存率,且對于雌激素受體陰性的乳腺癌患者來說,懷孕可以改善他們的總生存率。
因此,乳腺癌患者只要接受正規(guī)綜合治療,妊娠是安全可行的,只要患者有生育需求和意愿,均應(yīng)給予鼓勵。(責(zé)任編輯:shamouer)
