先是來個考古題勘誤
1.*P28 考古17題
我查到
Malignant trophoblastic disease develops in 20% of molar pregnancies. For this reason, quantitative hCG should be serially monitored.
原文請參考http://emedicine.medscape.com/article/254657-followup
所以答案選(d)
也可以這樣想:<感謝陳耕提供想法>
GTD(gestational trophoblastic disease)又分良性與惡性
1.良:Hydatidiform mole-治療後有80%會痊癒,
15%變incasive mole
5%變Choriocacinoma
2.惡:incasive mole
PSTT
Choriocacinoma
所以Hydatidiform mole轉惡性率為15+5%=20%
2.*關於尿液還是血液的hCG
Serum free beta-subunit or its urinary degradation product beta-core fragment
is produced by 68% of ovarian, 51% of endometrial and 46% of cervical
malignancies.
其實他們是一樣的東西
Since the management of GTD is often guided by the hCG level, it is important
to consider the possibility of a false-positive result, especially in
discordant clinical situations.
The presumptive diagnosis of either ectopic pregnancy or GTN has been the basis of unnecessary treatment.
A prime consideration is to obtain a urinary hCG level, since the substances do not appear to be excreted in their interfering form in the urine.
只是urine的比較不受干擾
所以共筆中只要後面有寫24小時的都是測尿中hCG累積量
其他則是單次測的serum hCG

3.*關於懷孕週數的疑義 出處仍參考上篇paper
這篇paper裡有較完整的共筆p7,講義p16左下表格內容
Stage I Nonmetastatic gestational trophoblastic disease
Stage II Metastatic gestational trophoblastic disease
A. Good prognosis
1. Urinary hCG level < 100,000 IU/24 h or serum hCG level < 40,000 IU/L
2. Symptoms present for < 4 months
3. No brain or liver metastases
4. No prior chemotherapy
5. Pregnancy is not term delivery
(ie, mole, ectopic, or spontaneous abortion)
B. Poor prognosis
1. Urinary hCG level > 100,000 IU/24 h or
serum hCG level > 40,000 IU/L serum
2. Symptoms present for > 4 months
3. Brain or liver metastases
4. Prior chemotherapeutic failure
5. Antecedent term pregnancy
根據此表可知共筆p15和p16的定義是說:
Symptoms present for < 4 months症狀出現時間小於4個月 good prognosis
Symptoms present for > 4 months症狀出現時間長於4個月 Poor prognosis
看了許多資料都是以duration of disease形容
意思上都是以'症狀'持續時間為主,應該也可以解釋成距之前懷孕時間
而共筆p7的WHO Scoring System in Metastatic Gestational Trophoblastic Disease
前胎懷孕:Preceding pregnancy,說得是前胎的狀態
上次懷孕距今多久:Interval (月)--Between the end of the preceding pregnancy
and the start of chemotherapy.
本項也就是上面的duration of disease
Pretreatment serum hCG (IU/mL):沒錯這裡的是血清hCG
完整分數算法請見

但這表與老師講義中有些許不同,考試時建議以老師的算法為主
3.*小提醒
絨毛膜癌
【治療】治療原則以化療為主,手術為輔,尤其是侵蝕性葡萄胎,
化療幾乎已完全替代了手術,但手術治療在控制出血、感染等併發症及切除
殘存或耐藥病灶方面仍占重要地位。
臨床痊癒出院後應嚴密隨訪,觀察有無復發。第1年內每月隨訪1次,1年後
每3個月隨訪1次,持續至3年,再每年1次至5年,此後每2年1次。
隨訪內容重點同葡萄胎。
老師說的f/u方式:術後連續每1-2周驗hCG,連續3周正常才算痊癒 共筆p12.18
葡萄胎
通常生產後或流產後,二至三個星期人類絨毛膜性腺激素會降至正常值。
但是葡萄胎在治療後,則須二至三個月才能降至正常值。
起初每週一次,到完全正常三次之後,改為每月追蹤一次,
共一年。一年內要以保險套或口服避孕藥避孕,第二年中每3個月抽一次,
若數值一直正常,則以後每 6個月追蹤一次hCG
老師說的f/u方式:術後每1-2周驗hCG,連續兩次<10才算痊癒 共筆p5
