4 其他案例比較 劉先生,就診科別:腦神經外科 診斷:顳葉惡性腫瘤 主要用藥:
Temozolomide 100mg/cap 3# QD 5days Temozolomide 20mg/cap 1# QD 5days

5 其他案例比較 吳女士,就診科別:腦神經外科 診斷:腦惡性腫瘤,放射線所致之影響 主要用藥:
Temozolomide 100mg/cap 3# HS 5days

6 TEMODAL (Temozolomide)
規格：20mg/cap 顏色：白/黃色 劑型：膠囊 形狀：長圓柱形 標記：有TEMODAL/20mg字樣 規格：100mg/cap 顏色：白/粉紅色 劑型：膠囊 形狀：長圓柱形 標記：有TEMODAL/100mg字樣

7 TEMODAL作用 具抗腫瘤活性,含有imidazotetrazine環的烷基化作用劑
它在全身循環中會在生理酸鹼值的狀態下,快速地透過化學轉化作用形成活性化合物MTIC(Monomethyl triazeno imidazole carboxamide)

8 TEMODAL適應症 新診斷的多形神經膠母細胞瘤,與放射治療同步進行,然後作為輔助性治療
給予標準治療後復發性或惡化之惡性神經膠質瘤,例如多形神經膠母細胞瘤或退行性星狀細胞瘤

9 TEMODAL用法用量 一.新診斷的多形神經膠母細胞瘤的成年病人

10 同步治療期 1. TEMODAL口服投與42天（75mg/㎡體表面積 /day),與放射治療同步進行
CTC非血液學毒性（禿髮,噁心,嘔吐除 外）≦第一級 ＊治療期間每週需測量一次全血球計數　　　　　　

11 輔助性治療期 4. 完成TEMODAL與放射治療同步治療之後四週,再給予六個療程的TEMODAL輔助性治療
a. 第一個（輔助性）療程的劑量是TEMODAL口服150mg/㎡體表面積,每天1次,投與5天,接著23天不用服藥 b. 開始第二個療程時,如果符合☆便可將治療劑量增加為200mg/㎡體表面積 ＊如果劑量在第二個療程沒有增加,以後的療程就不應該增加劑量 c. 以後每個療程最初5天的劑量要保持在200mg/㎡體表面積,除非毒性出現 ＊在治療期間,第22天（投與第1次TEMODAL 劑量的21天後）要測量全血球計數

12 二.患有復發性或進行性神經膠質瘤的成人 1.先前未曾接受過化療的病人:每28天為一個療程,投與5天,每天1次,口服TEMODAL 200mg/㎡體表面積 2.先前接受過化療的病人:在第一個療程投與初始劑量TEMODAL 150mg/㎡體表面積,在第二個療程的第一天,如果絕對嗜中性白血球計數≧15億個/L,血小板計數≧1000億個/L,便可將治療劑量增加為200mg/㎡體表面積

13 三.患有復發性或進行性神經膠質瘤的兒童病人
1.三歲或更大的兒童病人:每28天為一個療程,投與5天,每天1次,口服TEMODAL 200mg/㎡體表面積 2.先前接受過化療的兒童病人:在第一個療程投與初始劑量150mg/㎡體表面積,投與5天,如果沒有毒性,在第二個療程便可以將治療劑量增加為200mg/㎡體表面積,投與5天 ＊可以持續使用至疾病進行治療期最長為2年

14 「全民健康保險藥品給付規定」修正規定 第9章 抗癌瘤藥物 Antineoplastics drugs （自97年1月1日起實施）
修正後給付規定 9.25. temozolomide (如Temodal)：（94/3/1、97/1/1） 1. 限用於經手術或放射線治療後復發之AA(anaplastic astrocytoma) 或GBM (Glioblastoma multiforme)之病人。 ★2. 新診斷的多型性神經膠母細胞瘤，與放射線治療同步進行，然後作為輔助性治療。（97/1/1） 3. 需經事前審查核准後使用。 備註：劃線部份為新修訂之規定。 原給付規定 9.25. temozolomide (如Temodal)：(94/3/1) 1. 限用於經手術或放射線治療後復發之AA(anaplastic astrocytoma) 或GBM (Glioblastoma multiforme)之病人。 2. 需經事前審查核准後使用。
