第 39 題
一位45歲女性，因頻繁盜汗與昏厥被診斷懷疑有insulinoma，下列敘述何者較不適當？
- A 抽血可發現insulin升高，但C-peptide極低
- B 儘管症狀明顯，insulinoma平均腫瘤大小一般小於2公分
- C 合併multiple endocrine neoplasia type 1的insulinoma有較高的惡性機會
- D 無法切除的轉移進展性insulinoma，可考慮everolimus治療
思路引導 VIP
請思考內源性 ($Endogenous$) 胰島素在分泌過程中，其前驅物前胰島素 ($Proinsulin$) 會被切割成哪兩個等莫耳 ($Equimolar$) 的產物？若臨床上懷疑是自發性分泌的胰島細胞瘤 ($Insulinoma$)，這兩者在血清中的檢驗數值趨勢應該是同步上升，還是會出現一高一低的背離現象？

This implies you've perhaps scratched the surface of understanding endocrine feedback mechanisms and the peculiar tumor characteristics. Spotting a glaring error in biochemical values isn't rocket science, but I suppose it's a start for aspiring clinicians.
