子宮鏡在輔助診斷子宮內膜癌的角色

The role of hysteroscopy in the diagnosis of endometrial cancer

子宮內膜癌為最常見的婦科癌症之一，因為絕大部分均有症狀，所以在疾病的早期時即會被診斷出來。據估計約有80%的子宮內膜癌為第一期，而其他得期別很少，晚期的病人約只有5%。其中第一期的婦女經治療後，約有90%的五年存活率。然而，當癌症侵犯至子宮頸時的第二期， 五年存活率則明顯降至60～70%。子宮鏡在子宮內膜癌早期診斷和分期皆扮演一些角色，因為子宮鏡可將肉眼可見的病兆作切片處理，同時對於判定子宮頸是否侵犯有高準確度，這些因素皆可幫助我們針對病情作適當的治療計畫。此篇文章主要是針對術前子宮鏡的研究報告作完整的統和分析，試圖釐清術前子宮鏡檢查的分歧論點，並作為診斷性子宮鏡在疑似子宮內膜癌患者的參考。

Endometrial cancer is one of the most common gynecologic cancers. Most of them are symptomatic, resulting in an early detection. More then 80% of endometrial cancers are FIGO I, contributing to more than 90% of a 5-year survival rate. When the tumor invades to the cervix (FIGO II), the 5-year survival rate drops to 60-70%. Hysteroscopy may play a role not only for early detection but also for accurate stage. Under the assistance of hysteroscopy, lesion could be easily to be defined. Treatment for endometrial cancer could be guided by accurate pre-operative stage. In this review article, the role of hysteroscopy in the diagnosis of endometrial cancer is discussed.
