73歲陳先生在台北慈濟醫院接受大腸癌篩檢時糞便潛血呈陽性,進一步檢查確診直腸癌三期,接受放射與化學治療後進行微創直腸切除手術,目前恢復良好且近兩年未復發。醫師指出大腸癌約70%-80%由良性瘜肉進展而來,早期篩檢與治療是提高存活率的關鍵,第一期五年存活率可達90%以上。

大腸癌是台灣癌症發生率第二高的癌症,約70%-80%由良性瘜肉進展而來,有家族史者風險增加10%-20%。早期篩檢如糞便潛血檢查可發現病灶,但陽性不等於確診,需進一步大腸鏡檢查確定。

〔記者翁聿煌/新北報導〕73歲陳先生平時無明顯不適,去(2025)年初在醫院接受大腸癌篩檢時,糞便潛血檢查呈陽性,進一步接受大腸鏡檢查及病理切片後,確診直腸癌第三期,陳先生後續接受放射治療合併化學治療,完成療程後,由大腸直腸外科醫師進行微創直腸切除手術,目前恢復情形良好,持續回院追蹤,近兩年未有復發情況。
台北慈濟醫院大腸直腸外科醫師呂宗儒指出,大腸癌依腫瘤發生部位,主要可分為直腸癌、結腸癌與其他腸癌,呂宗儒醫師指出,約70%至80%的大腸癌是由良性瘜肉進展而來,其中有大腸癌家族史者,相較一般族群罹患風險約增加10%至20%;近年隨著生活與飲食習慣的改變,罹患人數逐年攀升,據衛生福利部2025年公布的資料,大腸癌已高居國人癌症發生率第二名。

副院長何景良表示,大腸癌相較其他癌症,較有機會藉由篩檢提早發現,若能在瘜肉或癌前病變階段即時處理,有助於在疾病進展前介入。且因大腸癌早期通常沒有明顯症狀,許多患者發現時病程已進入後期,因此及早發現、及早治療,是影響大腸癌預後的重要關鍵,根據統計,若能早期治療,大腸癌第一期五年存活率可達90%以上,第二期前期也能超過85%;但若發展至第四期,則下降至約16%。
糞便潛血檢查是大腸癌的主要篩檢,用以確認糞便中是否含有紅血球;如若陽性則需另外透過大腸鏡觀察病灶並進行病理切片,確診後,醫師會輔以電腦斷層、核磁共振或正子攝影等影像檢查,判斷腫瘤範圍、期別及是否轉移,作為後續治療依據。
常見治療方式包括手術、化學治療及放射治療,手術以切除腫瘤腸段及週邊淋巴結為原則,可視病況採用3D影像輔助腹腔鏡、達文西機器手臂進行,此等微創方式較傳統手術而言,具有傷口小、術後恢復快的優點,至於術後是否需要人工造口則視個人病況而定。
呂宗儒指出,定期接受糞便潛血篩檢是及早發現病灶的重要方式,但潛血陽性不等於確診大腸癌,發炎、痔瘡等情況也可能造成陽性反應,真正確診的比例約5%至6%,民眾不需過度緊張,但還是要完成大腸鏡,把出血原因釐清。

Minister of Health and Welfare Shi Chongliang pointed out that the evacuation of seriously ill patients from outlying islands currently relies on fixed-wing aircraft landing at Songshan Airport. Helicopters are unsafe due to environmental restrictions. He emphasized that there are no roads from outlying islands to the main island of Taiwan, and questioned Taipei Mayor Chiang Wanan’s plan to urgently transport patients by road or high-speed rail.

The Taiwan Egg Freezing Association announced the results of the 2026 Women's Fertility Preservation and Willingness Survey. More than half of women of childbearing age have a desire to have children. Even if they suffer from cancer in the future, 64.8% are willing to preserve their fertility opportunities through medical egg freezing. However, 63.8% of cancer patients are most worried about the financial burden. The National Health Service currently limits subsidies to breast cancer and blood cancer patients and the subsidy period is ten years. Experts recommend expanding the scope of subsidies based on the degree of fertility damage.

Hong Kong's Hospital Authority has issued an urgent public appeal for a liver donation for a 13-year-old boy at Queen Mary Hospital suffering from severe liver failure. The patient is currently at the top of the O+ blood group transplant waiting list.

The Ministry of Health and Welfare has launched the Dementia Care 3.0 Plan, with the goal of achieving "Dementia Friendly Taiwan 888" by 2035, that is, the diagnosis rate, service coverage rate, and specific field literacy rate will all reach 80%. The service targets are expanded to all age groups, and employment support and family care resources for young people with dementia are strengthened.

The latest international research points out that the atrial fibrillation detection function of smart watches has a high rate of misdiagnosis, leading to excessive medical treatment and public anxiety. Studies have shown that although the diagnosis rate has increased, the effect on reducing the risk of stroke or death is weak. Experts suggest that the alarm is for reference only and there is no need to panic blindly.

Forest and land fires in Indonesia have affected 63 counties and cities in 7 provinces, resulting in more than 277,000 cases of acute respiratory infection. The Indonesian Ministry of Health has deployed 2,106 medical personnel and distributed 3 million masks and medical supplies to the disaster-stricken areas, focusing on protecting the health of vulnerable groups such as infants and young children.
