• Correlation between the number and density of blood vessels in resected gastric cancers and the incidence of subsequent metastasis6,7

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

– 選擇咀嚼不費力或不需咀嚼的食物
103
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
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
– 手足症候群
– 腹瀉
– 口炎
中斷
Xeloda治療
痊癒後重新開始治療
105
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
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

Taxan mechanism
109
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
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
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
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
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。
114
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。
115
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
• 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

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
