⚡️癌症治療中常聽到"電療"是什麼?⚡️
✍️「電療」,其實就是醫學正式名稱的「放射線治療」,屬於非侵入性的腫瘤治療方式,本院電療又分為「光子治療」 與 「質子治療」,分別比較說明如下:
1️⃣治療原理:
🔆光子治療(傳統X光):射線具穿透性,殺死腫瘤時也會波及周邊正常肝臟組織。
📍質子治療:具有「布拉格尖峰」物理特性,能量能精準在腫瘤處釋放,大幅減少對正常組織的傷害。特別適合肝功能不佳、腫瘤較大或剩餘肝體積較小的病患。
2️⃣兩者優缺點比較:
🔆光子治療:
👍優點:健保給付(免費或部分配件自費),費用較低;腫瘤控制率”平均”較差、每日治療臥床時間短(約5~10分鐘)。
👎缺點:相對質子治療,腫瘤控制率較差、副作用風險較高。
📍質子治療:
👍優點:腫瘤控制率較高、對正常肝臟傷害低、副作用較少。
👎缺點:需全額自費(本院肝癌依不同狀況,約新台幣35-95萬元)、每日需固定不動時間長(約30~60分鐘)。
3️⃣決策建議:
若想要精準治療效果與較少副作用且預算充足,建議選擇質子治療;若考量經濟負擔或無法長時間平躺,則建議選擇光子治療
⚠️⚠️⚠️最終治療決策請務必與主治醫師共同研議共識。

⚡️What is " Radiotherapy " in Cancer Treatment?⚡️
✍️Radiotherapy can be further divided into two main types: "Photon Therapy" and "Proton Therapy" .
Here is a comparative explanation of the two:
1️⃣Treatment Principle:
🔆Photon Therapy (Conventional X-Ray): The rays have pe*******on power, meaning they kill the tumor but may also affect surrounding healthy liver tissue.
📍Proton Therapy: It utilizes the physical characteristic of the "Bragg Peak", allowing energy to be precisely released at the tumor site, significantly reducing damage to normal surrounding tissue. Particularly suitable for patients with poor liver function, larger tumors, or smaller remaining liver volume.
2️⃣Comparison of Pros and Cons
🔆Photon Therapy:
👍Pros : Covered by National Health Insurance (free or low-cost); short daily treatment time (approx. 5-10 minutes).
👎Cons :Relatively lower tumor control rate compared to proton therapy; higher risk of side effects.
📍Proton Therapy
👍Pros : Higher tumor control rate; lower damage to normal liver tissue; fewer side effects.
👎Cons : Requires full out-of-pocket payment (approx. NT$ 700,000 to 900,000); longer daily immobilization time (approx. 30-60 minutes).
3️⃣Decision Guidance:
📍Proton Therapy is recommended if you prioritize precise treatment efficacy and fewer side effects, and have a sufficient budget.
🔆Photon Therapy is recommended if you must consider the financial burden or are unable to lie still for extended periods.
⚠️⚠️⚠️Final Note: The ultimate treatment decision must always be discussed and agreed upon with your treating physician.
