【肺癌免疫療法下午3前進行效果特佳.正氣強弱對抗癌的影響】
剛剛看到中大有關肺癌治療的最新研究,由於近日收了幾個肺癌患者,特別留意了一下。研究指,晚期肺癌患者在下午三時前進行聯合免疫治療共化療,成效顯著加強,無惡化存活期延長近一倍,其整體存活率中位數亦高出近七成。是次研究結果已於國際頂尖醫學期刊《自然醫學》發表。
同一樣的療法,同一樣的病,只是治療時間的不同,就有這樣大的分別,原因是什麼呢﹖論文指可能和人體的生理時鐘有關。而從中醫的角度看,可能和人體正氣的強弱有關。
從中醫學的角度看,大家以為的深夜(凌晨11pm-1am,子時)反而是陽氣萌發的時間。因為已經是黑夜的盡頭了,陰氣最盛,而陽氣慢慢萌發。到了卯時 (5am–7am),陽氣顯著生發,天就亮了,人開始起床活動。
一直到了日照中天的午時 (11am至1pm),陽氣達到頂點,同時也是陰氣開始產生的時間。所以古代問斬是在午時的,因為它是陰陽轉換的時刻。
到了研究中的時間1pm-3pm,屬於未時。古人稱此時為「日昳」、「日跌」或「日側」,意指太陽偏西、開始由最高點緩緩落下。下這時候陰氣已生了2個時辰,再來就是黃昏了。
從這樣看來,下午3時前,陽氣是偏多的;下午3時後,陽氣就漸減了。免疫治療是一種增強或調節人體自身免疫系統,來辨識並對抗癌細胞的癌症療法;動用的是人體本身的正氣,因此早點進行,正氣較強,可以激發出更多的抗癌能力。
我平日常說,補益的藥物,盡量早飲;如果工作實在忙不過來,夜上寧願不喝。因為太夜服補藥,反而太燥,令人睡不著。

【下午三時前免疫治療更有效】中大醫學院最近一項多中心研究發現,晚期肺癌患者在下午三時前進行聯合免疫治療共化療,成效顯著加強,無惡化存活期延長近一倍,其整體存活率中位數亦高出近七成。是次研究結果已於國際頂尖醫學期刊《自然醫學》發表。
肺癌是全球最致命的癌症,也是香港最常見及死亡率最高的癌症,每年新症超過6,000宗,其中非小細胞肺癌約佔所有肺癌病例的85%。聯合免疫治療共化療是晚期非小細胞肺癌患者的一線標準治療方案。
生理時鐘與免疫功能息息相關。有回顧性研究指出,按生理時鐘安排免疫治療時間,或有助改善治療效果。
為驗證此關聯,研究團隊招募210名晚期肺癌患者,將他們隨機分為兩組,分別在上午組(下午三時前)及下午組(下午三時後)接受治療。結果顯示,相較下午組,上午組的無惡化存活期延長近一倍,整體存活率亦高近七成,疾病惡化風險及死亡風險分別下降60%,顯示上午治療或更有利於激活和增強免疫反應,從而加強治療成效。
李樹芬醫學基金腫瘤學教授、中大醫學院副院長(科研轉化及創業)及腫瘤學系系主任莫樹錦教授表示,這是醫學界首次有大型前瞻性的隨機研究,將人體生理時鐘與癌症免疫治療的成效直接聯繫起來。研究結果令人鼓舞,在毋需增加患者或醫療系統成本的情況下,只需透過調整治療時間,就有可能增強治療成效及延長存活期。

【Immunotherapy before 3 p.m. helps patients live longer】 CU Medicine’s recent multi-centre study reveals that immunochemotherapy administered before 3 p.m. significantly enhances efficacy in advanced lung cancer patients, nearly doubling progression-free survival (PFS) and increasing median overall survival (OS) by almost 70%. The findings have been published in the internationally renowned medical journal Nature Medicine.
Lung cancer is the deadliest cancer worldwide and remains the most common and deadliest cancer in Hong Kong, with over 6,000 new cases each year. Non-small cell lung cancer (NSCLC) accounts for about 85% of all lung cancers. The combined use of chemotherapy and immunotherapy has been confirmed as the standard first-line therapy for patients with advanced-stage NSCLC.
The human circadian clock is closely associated with immune function and prior retrospective studies suggested that application of immunotherapy according to the circadian cycle may optimise treatment efficacy.
To verify the association, 210 patients with advanced NSCLC were enrolled from China, randomly assigned to receive treatment before and after 3 p.m., respectively. The PFS and OS of the morning cohort (before 3 p.m.) were found to far exceed those of the afternoon cohort, with 60% lower risks of disease progression and risk of death, indicating that morning treatment may help activate and enhance the immune response, resulting in better therapeutic efficacy.
Professor Tony MOK, Li Shu Fan Professor of Clinical Oncology, Associate Dean (Translation and Entrepreneurship) and Chairman of the Department of Clinical Oncology at CU Medicine pinpointed that the study, which represents the first large-scale prospective randomised study to establish a direct association between the human biological clock and the effectiveness of cancer immunotherapy, is highly encouraging as a simple adjustment to the timing of treatment may enhance therapeutic efficacy and improve survival at no additional cost to patient or healthcare system.
