美國俄亥俄州立大學韋克斯納醫學中心對18名黑色素瘤患者進行流感疫苗直接注入腫瘤的小型臨床試驗,7人腫瘤出現消退跡象,3人手術切除組織中未發現癌細胞。研究結果於11月在美國鳳凰城癌症免疫治療學會年會發表,但試驗無對照組,尚無法確認療效來源。

流感疫苗通常用於預防流感,本研究嘗試將其直接注射進腫瘤,期望引發局部免疫反應。俄亥俄州立大學團隊計畫接下來結合免疫檢查點抑制劑,測試對無法手術切除的轉移性黑色素瘤是否有幫助。丹麥研究團隊曾對10名大腸直腸癌患者進行類似試驗,腫瘤內免疫細胞增加但腫瘤未明顯縮小。

〔編譯陳成良/綜合報導〕一般用來預防流感的疫苗,被直接注射進皮膚癌腫瘤內,竟達成療效。這是真的嗎?美國俄亥俄州立大學韋克斯納醫學中心進行一項小型臨床試驗,18名黑色素瘤患者接受這項實驗性治療,其中7人的腫瘤出現消退跡象,更有3人手術切除的組織中已找不到癌細胞。
《華盛頓郵報》報導,這項初步研究結果於11月在美國鳳凰城舉行的癌症免疫治療學會(SITC)年會發表。研究團隊希望藉由流感疫苗在腫瘤內引發免疫反應,吸引更多免疫細胞進入腫瘤。
試驗對象都是可透過手術切除的黑色素瘤患者。研究人員先在患者手臂施打一劑流感疫苗,幾天後再直接注射進腫瘤,並於第12天進行第二次注射。多數患者每次接受的腫瘤內注射劑量約為一般流感疫苗的3倍,試驗期間無人出現嚴重副作用。
第二次注射約兩週後,醫師手術切除腫瘤並檢查組織,發現多數樣本都有免疫細胞進入;血液檢查也觀察到發炎訊號及免疫抑制細胞出現變化。
現成流感疫苗注入腫瘤 探索低成本免疫療法
研究人員推測,流感疫苗可能在腫瘤內引發類似感染的免疫反應,改變原本抑制免疫細胞的腫瘤環境,促使更多免疫細胞進入並辨識癌細胞。
這種做法與個人化癌症疫苗不同。後者必須依患者腫瘤特徵量身製作,流感疫苗則是現成產品,不必重新設計,具有降低治療成本的潛力。
不過,這項試驗只有18名患者,且沒有對照組,目前無法確認腫瘤消退是否由疫苗注射造成,也只適用於能以針頭直接注射的腫瘤。
丹麥研究團隊曾透過內視鏡,對10名大腸直腸癌患者進行類似試驗,雖然腫瘤內免疫細胞增加,腫瘤卻沒有明顯縮小。俄亥俄州立大學團隊接下來計畫結合免疫檢查點抑制劑,測試對無法手術切除的轉移性黑色素瘤是否有幫助。

Hong Kong will become the first Asian city to conduct clinical trials of histotripsy, a non-invasive kidney tumour treatment, with the Li Ka Shing Foundation funding places for 30 patients across CUHK Medical Centre, Gleneagles Hospital Hong Kong, and Hong Kong Sanatorium & Hospital.

69-year-old Uncle Qin was pricked by a fishbone on his right palm while handling tilapia. Three days later, he developed a high fever, redness, swelling and blisters on his arms. He was diagnosed with Vibrio vulnificus infection and was discharged from the Shenzhen Third People's Hospital after 16 days of treatment. Doctors remind people to wear gloves when handling seafood, and those with wounds should avoid contact with seafood and seawater. If the wound is red, swollen and has a fever, seek medical attention immediately and inform them of the seafood bite.

You Guantang, a psychosomatic physician, pointed out that Double 11 limited-time promotions can easily induce impulse purchases. It is recommended that consumers make a list and set a budget before checking out. Store items not on the list for the next day before making a decision. If you repeatedly cannot control your shopping impulse, you can seek professional assistance.

Liu Boren, director of the Cobot Clinic, said that although black fungus contains polysaccharides that may have antioxidant and blood lipid-regulating effects, there is no clinical evidence in humans to prove that it can remove blood vessel plaques or prevent myocardial infarction. Patients taking medication should not stop taking the medicine on their own. Soaking dried black fungus at room temperature for a long time may increase the risk of contamination by microorganisms such as bunkeric acid. You should cook it as soon as possible after soaking it for a short time and keep it refrigerated if necessary.

In response to the "Health Coin" policy of the Ministry of Health and Welfare, Chimei Medical Center took the lead in China on October 22 to launch the "Colleagues Donate Blood to Get Health Points" campaign. Donating 250cc of blood will earn you 250 points, and donating 500cc will earn you 500 points, which can be used as discounts in the hospital restaurant. In the future, it is planned to be used for health examinations and self-paid vaccines. During the event, colleagues donated a total of 21,500 cc of blood. 90.6% of the participants agreed that daily health should be paid more attention to by combining health points, and 96.9% hoped that the Ministry of Health and Welfare would include blood donation in the health coin reward program.

A Korean study found that if women eat instant noodles more than twice a week, compared with those who eat less than once a month, the correlation with metabolic syndrome is about 1.68 times; after excluding those with diabetes and taking medication, it is about 1.83 times. The association of the subgroup of women with a BMI lower than the median was 5.22 times, but this was a small sample analysis. No significant association was observed in men.
