研究發現胰臟癌惡病質形成機制:腫瘤細胞、巨噬細胞與癌症相關纖維母細胞形成微環境

Quick Look

美國奧克拉荷馬大學研究團隊利用單細胞定序與空間轉錄體分析發現,胰臟癌惡病質(肌肉與脂肪流失)與腫瘤細胞、巨噬細胞及癌症相關纖維母細胞形成的微環境密切相關,這些細胞群在明顯消瘦前即已出現,有望成為早期辨識高風險患者的線索。

Why It Matters

胰臟癌晚期患者常見惡病質(cachexia),導致體重、肌肉與脂肪持續下降,單靠增加熱量攝取難以逆轉,影響治療耐受度與生活品質。

〔編譯陳成良/綜合報導〕罹患胰臟癌後,部分患者會出現明顯消瘦,甚至同時流失肌肉與脂肪。美國奧克拉荷馬大學(University of Oklahoma)研究團隊最新發現,腫瘤周遭有3群彼此緊密連結的細胞,可能共同推動這種稱為「惡病質」(cachexia)的消耗性變化。

奧克拉荷馬大學醫學院

研究團隊9月29日於國際知名學術期刊《細胞》(Cell)發表研究,利用單細胞定序與空間轉錄體分析,觀察不同階段的胰臟癌樣本,找到3類特定細胞群,包括腫瘤細胞、巨噬細胞,以及癌症相關纖維母細胞。研究顯示,這些細胞彼此靠近,形成一個與惡病質相關的微環境。

請繼續往下閱讀...

肌肉脂肪流失前 異常細胞群已出現

研究指出,這3群細胞並非各自獨立運作,而是形成相互影響的調控網絡;隨著惡病質加重,相關細胞群也會增加。研究團隊並發現,這些細胞群可能在明顯的肌肉與脂肪流失發生前就已形成,因此有望成為辨識惡病質高風險患者的線索。

「惡病質」是一種癌症引發的消耗症候群,會造成體重、肌肉與脂肪持續下降,單靠增加熱量攝取未必能扭轉這種變化。美國國家癌症研究院(NCI)指出,這種情況在晚期胰臟癌中特別常見,體重與肌肉流失也可能影響患者的身體功能及接受治療的能力。

奧克拉荷馬大學研究團隊表示,下一步將尋找能夠鎖定這3類細胞及相關分子的方式,希望進一步發展針對癌症惡病質的治療策略;研究團隊也強調,未來相關治療仍需與胰臟癌本身的化療或標靶治療搭配,並非取代既有癌症治療。

奧克拉荷馬大學醫學院目前這項研究主要提供的是胰臟癌惡病質形成機制的新線索,尚不是已證實可以阻止患者消瘦的新療法。

Research finds that people who are deprived of life due to smoking are more likely to try to quit smoking but have lower success rates

A study of 26,888 smokers in Australia, the United Kingdom, Canada and the United States showed that in 2024, 18.3% of Australian smokers were short of daily necessities due to purchasing cigarettes, which is called "smoking-induced deprivation." This group often tries to quit smoking but the success rate is only 9.4%, which is lower than the 12.6% of those who have not experienced deprivation in life. The study points out that high nicotine dependence and low confidence in quitting smoking are key factors, and recommends that tobacco tax revenue be used to support smoking cessation rather than simply reducing cigarette prices.

The North City Artist Inspection Center serves as a health promotion ambassador and takes the lead in receiving publicly funded influenza and new crown vaccines.

The Taipei City Health Bureau has provided publicly funded influenza and COVID-19 vaccines since October 1. Artists have taken the lead in vaccination as health promotion ambassadors. Eligible Taipei City residents who have completed the vaccination can participate in a lottery. Prizes include iPhone 17 and other home appliances and gift certificates. The influenza vaccine is trivalent, and the COVID-19 vaccine has been upgraded to the XFG generation. The antigen dose has been reduced to 1/5 of the previous generation, and adverse reactions have been halved. Vaccination will be open to everyone in phases.

Tainan’s publicly funded flu and COVID-19 vaccinations start, and you can get health coins after vaccination

Tainan Mayor Huang Weizhe announced that publicly funded influenza and COVID-19 vaccines will begin on October 1. Vaccine recipients can receive health coins ranging from 450 to 900 depending on the type of vaccine. The city government has prepared sufficient vaccines and established a reservation system. It calls on high-risk groups to vaccinate as soon as possible to reduce the risk of severe illness.

Publicly funded influenza and COVID-19 vaccines will be available from October 1, 2026. Nutritionist Gao Minmin recommends supplementing protein, zinc, and vitamin A before vaccination, taking vitamins C, D, E, and Omega-3 after vaccination, and avoiding foods high in oil, salt, and sugar to stabilize immune cells and enhance repair capabilities.

NTU Cancer Center holds liver cancer health education exhibition to share three cases of multi-specialty integrated care

The National Taiwan University Cancer Center held a liver cancer health education exhibition to share the multi-specialty integrated care experience of three patients, including Mr. Wang who first took medication to shrink the tumor and then underwent surgery and survived for more than five years. Mr. Huang was discharged after three days of treatment with a single tissue morcellation knife due to his need for kidney dialysis. Ms. Yang switched to homeopathy due to her advanced age and risk of adjacent blood vessels, emphasizing that treatment requires personalization and teamwork.

Doctor’s reminder: It takes two weeks for the flu vaccine to produce antibodies, so please take it as soon as possible before going abroad

Wu Yifan, an attending physician at the Department of Family Medicine at Taipei City United Hospital, pointed out that it takes about two weeks after influenza vaccination to produce sufficient antibodies, and called on the public to get vaccinated as early as possible during the epidemic season or before traveling abroad to avoid the protective window period. It is also recommended that high-risk groups consider vaccination against COVID-19 and Streptococcus pneumoniae vaccines, and is reminded to seek medical advice immediately if severe symptoms occur when seeking medical treatment overseas.
