【摘要】目的 探討罕見苗勒氏管腺肉瘤的臨床診斷、治療及預后。方法 收集我院2012年6月~2015年6月收治的苗勒氏管腺肉瘤9例,分析其臨床病理特點、診斷、治療及預后,并進行文獻復習。結果 9例患者平均發(fā)病年齡(53.0±7.2)歲,主要臨床癥狀為不規(guī)則陰道流血,占66.7%,F(xiàn)IGO I期3例、II期5例、III期1例。予以全子宮切除并相關淋巴結清掃加紫杉醇和順鉑的聯(lián)合化療,其中6 例輔以術后放療,其平均PFS 和OS分別為(11.2±3.8)月和(17.2±4.6)月,另3例未接受放療患者平均PFS 和OS分別為(7.4±2.8)月和(13.4±3.5)月。結論 全子宮切除加淋巴結清除術加順鉑聯(lián)合紫杉醇化療,同時輔以術后放療有助于改善其預后。

Objective To explore the clinical diagnosis,treatment and prognosis of Mullerian adenosarcoma. Methods 9 cases of Müllerian adenosarcoma were collected from June 2012 to June 2015 to analyze their clinical features,diagnosis,treatment,prognosis,and reviewed the related literature.Results The average age of the 9 cases was(53.0±7.2)years old,and the main clinical manifestation was irregular vaginal bleeding. 3 cases were in FIGO stageⅠ,5 cases were in FIGO phase Ⅱ,and only one case was in phase Ⅲ. The treatment strategies were panhysterectomy with pelvic lymphadenectomy combined TP chemotherapy. 6 cases among of them were underwent the postoperative radiotherapy additional. The average time of PFS (Progression-Free Survival) and OS (Overall Survival) of postoperative radiotherapy patients were(11.2±3.8)months and (17.2±4.6)months,correspondingly,while the other 3 cases without postoperative radiotherapy were(7.4±2.8)months and(13.4±3.5) months,correspondingly.Conclusion Panhysterectomy with pelvic lymphadenectomy and taxol and cis-platinum chemotherapy combined of postoperative radiotherapy would ameliorate the prognosis of Müllerian adenosarcoma.

苗勒氏管腺肉瘤(Müllerian adenosarcoma,MA)又稱子宮癌肉瘤(Uterine carcino Sarcoma,CS),或稱子宮惡性中胚葉混合瘤(Malignant Mixed Mesodermal Tumor,MMMT),是由癌與肉瘤兩種成分組成的惡性腫瘤,是子宮肉瘤中一種罕見類型。子宮肉瘤發(fā)病率為1.23~1.70/10 萬,約占子宮體惡性腫瘤的2%~8%[1],苗勒氏管腺肉瘤約占子宮肉瘤的5%[2],惡性程度極高,早期即可發(fā)生轉移,特別是具有肉瘤樣過度生長型預后更差,目前尚無理想的治療方案[3]。本研究通過對我院近3年收治的子宮癌肉瘤9例進行診治分析并結合文獻復習,以期為其臨床診治提供更多參考。
1.1 臨床資料
回顧性分析重慶醫(yī)科大學附屬第一醫(yī)院腫瘤科2012年6 月~2015 年6 月收治的苗勒氏管腺肉瘤11例,通過CT和MRI檢查,分段診刮病檢及術后病檢診斷為子宮內(nèi)膜癌肉瘤。采用FIGO分期法,其中I期3例,II期5例,III期1例,IV期2例,排除IV 期2例后共納入9例入本研究。年齡為39~65歲,平均(53.0±7.2)歲。首發(fā)癥狀為不規(guī)則陰道流血6例,其中絕經(jīng)后陰道流血4例;沒有任何癥狀僅在體檢時發(fā)現(xiàn)異常2例,治療前患者Karnofsky 評分均≥80 分。(見表1)
1.2 治療方法
所有患者均采用手術及化療結合療法,其中6例還進行術后的輔助放療。手術方式:其中I期、II期患者8例為全身麻醉下行腹腔鏡下全子宮+雙側輸卵管卵巢切除術+雙側盆腔淋巴結+腹主動脈旁淋巴結清掃術;III期1例患者采用全身麻醉下經(jīng)腹子宮全切術+雙側輸卵管卵巢切除術+雙側盆腔淋巴結+腹主動脈旁淋巴結清掃術(見表1)。術后1周開始行TP方案化療:紫杉醇靜脈+順鉑,劑量由公式計算得出:紫杉醇劑量區(qū)間=[(135 ~175)mg]×[(體表面積)/m2)],順鉑劑量=75 m×[(體表面積)/m2)],體表面積(女)/m2=0.007 3×身高+0.012 7×體重-0.210 6,每4周1次,進行4~6個周期,平均(5.2±0.8)次。放療:6例在第1次化療完后進行50 Gy/25F的手術區(qū)域+盆腔淋巴引流區(qū)的精確放療,其他3例由于各種非醫(yī)療原因未進行放療。對于復發(fā)腫瘤給予補救化療及轉移灶的放射治療,不納入本研究統(tǒng)計。
1.3 療效評價
所有患者在接受手術治療+4 個周期以上的TP 治療+放射治療后進行療效評價。依據(jù)WHO 實體瘤療效評價標準(RECIST 1.1 版,2009 年)進行判斷,分為:腫瘤完全緩解(Complete Response,CR);部分緩解(Partial Response,PR),穩(wěn)定(Stable Disease,SD)和疾病進展(Progressive Disease,PD)。應用CT、MRI及腫瘤標志物來判斷患者首次治療后無進展生存期(PFS:Progression-Free Survival)及總生存期(OS:Overall Survival),具體見表1。
表1 9例子宮癌肉瘤患者的臨床資料
苗勒氏管腺肉瘤是一種罕見的、具有高侵襲性的婦科惡性腫瘤,特別是具有肉瘤樣過度生長的患者預后更差。其臨床表現(xiàn)多為絕經(jīng)后不規(guī)則陰道流血或宮頸新生物,發(fā)病機制尚不清楚。因其較早即可發(fā)生淋巴道轉移,廣泛應用手術切除、淋巴結清掃,術后輔助紫杉醇加順鉑化療及淋巴引流區(qū)的精確放療有助于改善其預后。
