預防手足症候群

www.cancer.net. Accessed on 15 May 2009

• 您應建議病患– 使用冰袋或冷敷(cool compress)的方式冷卻手

腳– 在坐姿或臥姿時將手腳抬高– 清洗後小心拍乾皮膚– 擦拭溫和的護膚乳液以保持雙手溼潤– 穿著寬鬆、透氣的鞋子與衣物

101

預防腹瀉

• 您應建議病患避免

– 飲用或食用咖啡因、酒類、乳製品、脂肪、纖維、柳橙汁、梅汁以及辛辣食物

– 使用瀉藥與軟便劑

www.cancer.net. Accessed on 15 May 2009

• 您應建議病患– 少量多餐– 每天至少喝2公升的水以預防脫水

102

Page 103: 胃癌Gastric Cancer 鑑古知今From Past to Future

預防口炎

• 您應建議病患避免

– 食用酸、辛辣、鹹、粗糙或乾燥的食物

www.cancer.net. Accessed on 15 May 2009

• 您應建議病患

– 使用含氟牙膏輕輕刷牙

– 使用牙線輕輕剔牙

– 移除假牙

– 選擇咀嚼不費力或不需咀嚼的食物

103

Page 104: 胃癌Gastric Cancer 鑑古知今From Past to Future

管理不良反應

• 常規病患追蹤程序(電訪或額外回診檢查)可協助確保不良反應管理達到 佳效果

– 特別是首次服用Xeloda的病患

104

Page 105: 胃癌Gastric Cancer 鑑古知今From Past to Future

中斷Xeloda治療• 發生中度(第2級)或更嚴重的出血性不良反

應時,應中斷Xeloda治療

– 腹瀉

– 口炎

中斷

Xeloda治療

痊癒後重新開始治療

105

Page 106: 胃癌Gastric Cancer 鑑古知今From Past to Future

中斷Xeloda治療不是病患唯一能採取的做法!

• 應在發生中度或更嚴重的不良反應時,告知病患停用Xeloda是正確的做法,但不是唯一的選擇

– 病患必須進一步徵詢您或其醫師之建議!

106

Page 107: 胃癌Gastric Cancer 鑑古知今From Past to Future

管理手足症候群

• 應在發生中度或更嚴重程度的手足症候群時,建議病患

– 停用Xeloda,並徵詢其腫瘤科護士/腫瘤科醫師之建議

– 使用潤膚劑/乳液

Docetaxel/ Paclitaxel

• 施打前之預防藥物:– Dexamathsone: 4-8 mg x 3 (給藥前晚上, 早

上以及傍晚)

• 目的﹕– 延遲體液滯留發生的時間及嚴重程度。– 降低過敏反應的發生率。– 可能降低嚴重皮膚反應的發生率

110

Page 111: 胃癌Gastric Cancer 鑑古知今From Past to Future

副作用及注意事項 (1)過敏反應雖然使用口服類固醇前處理藥物可降低過敏反應的

頻率及嚴重程度﹐護理人員仍應該警覺可能發生的過敏反應。輸注期間若觀察到嚴重過敏反應﹐應該立即停止給藥﹐並即時給予適當治療。下列急診用藥在治療過敏反應發生時應能隨時取用diphenhydramine, 50 mg, IVnoradrenaline, 1 ml, 1/1000, IVmethylprednisolone, 125 mg, IVdexamethasone, 10 mg, IVsalbutamol nebules and nebulizer

為了降低過敏反應的發生率﹐建議輸注的前5分鐘輸注速度變慢﹐然後持續依照既定速度輸注1小時。

111

Page 112: 胃癌Gastric Cancer 鑑古知今From Past to Future

副作用及注意事項 (2)

• 血管外滲不會引起全身性毒性。– 腫脹及/或輕微疼痛– 紅斑– 靜脈輸注部位無血液回流

• 外滲(extravasation)的處理– 立即停給藥﹐– 抽吸IV注射針﹐– 移除IV注射針﹐– 在輸注部位冰敷15~20分鐘﹐並告知病患回家後接

下來的72小時﹐每4~6小時重複一次。或依照一般原則立即處理及告知病患回家後處理方式。

112

Page 113: 胃癌Gastric Cancer 鑑古知今From Past to Future

副作用及注意事項 (3)

• 嗜中性白血球減少症Neutropenia– 嗜中性白血球減少症的發生迅速( 低點的中數

在第8天)且恢復快速(通常在1週內)。– 嗜中性白血球減少症可能發生在病患回家以後。

因此﹐病患應該被告知發生感染的可能性﹐若病患感覺不適即應該監測體溫。若體溫高於38℃﹐則應該告知其治療中心。

– 當病患服用類固醇和處在嗜中性白血球減少症的危機中﹐更應該特別注意口腔衛生。

113

Page 114: 胃癌Gastric Cancer 鑑古知今From Past to Future

副作用及注意事項 (4)

• 體液滯留Fluid retention– 體液滯留並非是危及生命的不良反應﹔它與累

積劑量有關。通常發生在數個治療周期之後(發生之累積劑量中數為797 mg/m2)﹐類固醇前處理藥物明顯降低體液滯留的發生率﹑嚴重程度並延後症狀之發生。

– 體液滯留可觀察到病患有水腫﹑體重增加﹐少數病患會有胸肋膜滲出液﹑腹水或心包膜滲出液。

– 若有體液滯留情況發生時﹐根據體液滯留嚴重情況加上furosemide或spironolactone。長期使用利尿劑應該小心。

副作用及注意事項 (5)• 皮膚﹑神經學及胃腸方面的反應

– 若有皮膚乾燥或潮濕脫皮現象﹐病患應被建議採取溫水浴﹐採用無香水的香皂﹐並在乾燥皮膚區域敷上水性乳霜。若有皮膚癢的情況﹐可用抗組織胺作症狀處理。

– 曾有報告顯示pyridoxine, 口服﹐50 mg﹐每天三次﹐可減輕改善感覺遲鈍觸痛等現象。

– 胃腸方面的副作用﹐確定病患出院時有開立適當的止吐劑﹐止瀉劑。

– 勸導病患密切注意口腔衛生﹐使用軟質牙刷及處方的牙膏製品。

– 若口腔有傷口﹐勸導病患避免太辣太鹹的食物。

副作用及注意事項 (6)

• 無力﹑關節痛及肌肉痛

– 無力感發在三分之二的病患﹐約有12 %的案例為程度嚴重。

– 關節痛及肌肉痛一般為輕度至中度。病患應被告知使用時﹐因為這些症狀病患的生活品質可能會有所影響。使用輕度止痛劑便可有效減輕關節痛及肌肉痛。

Oxaliplatin Mechanism

Page 118: 胃癌Gastric Cancer 鑑古知今From Past to Future

Oxaliplatin

• 須給病人適當止吐藥(and/or)。

5‐HT3 antagonist: Aloxi, setoral, kytril… Dexamethasone  Primperan:Gastro‐T Novamin 5 mg

• 如病人因疑慮而產生咽喉感覺異常時

抗焦慮藥品可能對病人有幫助。

• 神經毒性:

Cal. Gluconate (1 gm) + MgSo4 (1 gm) in D5W 100 cc run 15‐30 mins before & after Oxaliplatin

副作用及注意事項 (1)周圍感覺神經異常1. 常見的副作用,與個人的體質、治療的劑量、

治療時間的長短有關。2. 當進行治療時,四肢末端以及(或)口腔周圍可

能會產生刺痛感或感覺變得較不敏銳。而這些症狀通常在數小時或數天後便會自動緩解。

3. 較冷的環境,可能會引發或是加劇上述的副作用。應盡量避免暴露於寒冷的環境下。

119

週邊感覺神經異常

• 如發生神經毒性,請詢問病人以下問題:症狀型態:

感覺異常、遲鈍、過敏,疼痛,麻木,肌肉收縮,虛弱等等。

症狀發生的位置:肢端,口腔周圍的區域。

症狀與低溫的關聯性。症狀持續的時間:

開始時間與Oxaliplatin輸注時間的關聯性,症狀持續的時間(暫時性或持續性)。

症狀的嚴重度:是否伴隨著功能的障礙。 120

Oxaliplatin的神經毒性急性暫時性神經病變 蓄積性感覺神經病變

作用機轉

Oxaliplatin代謝物oxalate,可能經與鈣離子鉗合會阻擋鈉離子通道。

機轉不清楚,由急性暫時性神經病變逐漸衍生而來。

發生率

輕微遠端及/或口腔周圍皮膚感覺異常以及/或感覺遲鈍:85-95 %暫時性咽喉感覺遲鈍,導致感覺呼吸困難或吞嚥困難:10-20 %

10-18 %

經歷

發生於第一次治療 大部分累積性毒性會經歷急性症狀感覺遲鈍或異常等症狀在兩次治療週期間會持續存在

症狀

肢體末梢以及/或是口腔周圍的感覺異常

進一步進展成功能性障礙:精細的感覺、運動協調性失常,感覺失調

誘因

低溫會引發或讓副作用情況更加惡化

累積劑量780-850mg/m2

Oxaliplatin 130 mg/m2q3w 6 cyclesOxaliplatin 85 mg/m2 q2w 9 cycles

時間

數小時或數天症狀便會消失

治療停止後3-5個月,75 %會回復至第一級蓄積性神經病變或更輕微症狀。

急性暫時性神經病變 蓄積性感覺神經病變

嚴重症狀

輸注過程或結束:1.偶發咽喉感覺異常、敏感度降低

2.暫時感覺呼吸或吞嚥困難(不會發生呼吸困難)

3.肌肉收縮:痙攣或抽筋,手腳僵硬感,

手掌握拳後無法張開,有時影響腿或導致下巴收縮。

使用Oxaliplatin治療的病人不曾有過麻痺或癱瘓報告。

約<15 %病人會發生感覺功能障礙。

原因 臨床類似強直性痙攣,運動神經元過度興奮及脊椎抑制性神經元間突觸釋放神經傳導物質時出現異常造成。

神經的過度興奮或是肌肉的過度興奮所造成。

解決方式

輸注時間由2小時延長至6小時 治療停止後會逐漸改善或消失

其他 劑量為130mg/m2時,比Oxaliplatin的劑量85mg/m2發生的機率高。

週邊感覺神經異常病患接受化學治療後五日內應注意下列各事項:1. 避免暴露於寒冷或強風的環境。在冷空氣中,可

使用口罩或圍巾保護口、鼻。2. 需注意保暖,感覺冷時,可穿戴毛衣、圍巾、手

套。在室內時可用溫水暖手。3. 避免用冷水洗手。4. 避免碰觸冷的東西或物体。從冰箱中拿取食物時,

好穿戴手套。當病人的這些症狀持續發生或變得更加嚴重,應該向醫師反應,請醫師替病患調整藥品的使用劑量。

Summary

• Early diagnosis, Early treatment • Adjuvant chemotherapy is beneficial, but managing side effect is team work.

• Stage IV is not “ terminal” , prolong life is possible.
