＊胰臟腫瘤可大體分成兩大類

1.外分泌腫瘤：大部分是duct cell origin，極少數源於acinar cell

2.內分泌腫瘤：
insulinoma
gastrinoma
VIPoma
glucagonoma
somatostatinoma
GRFoma
PPoma and nonfunctional tumors

＊由於大部分的胰腫瘤均來duct cell，我們的重點乃放在duct cell origin的腫瘤：

1.Benign solid adenoma
-cystadenoma
2.Malignant solid adenocarcinoma
-cystadenocarcinoma

＊pancreatic adenocorcinoma
症狀：常見的症狀為黃疸、上腹痛、體重減輕、消化不良，部分病人併發胰臟炎（急性或慢性均有）
courvoisier's sign：a distended and palpable gall bladder，多見於胰頭癌
Trousseau's syndrome：migratory thrombophlebitis，多見於胰體部及尾部的癌
R診斷：EUS. ERCP. CT, Abdominal ultrasound,fine needle aspiration of tumor,tumor marker
‾治療

a.手術療法：只有10%∼20%的病人，可以手術切除，且預後不佳
b. 化學治療
c.放射＋化學治療
d. 對於無法切除的胰癌所致的阻塞性黃疸：
by-pass surgery（biliary by-pass+gastrojejunostomy）或endoscopic stenting（or PTCD with stenting）

＊cystadenoma and cystadenocarcinoma

1.Mucinous cystadenoma or cystadenocarcinoma：
　a. Mucinous lesions have malignant potential and should be resected
　b. Found mainly in younger women

2.serous cystadenoma（Microcystic）：
　a. Middle-aged or elderly woman
　 b. Benign lesions
