错误 已被科学证据否定 证据确定性: 高 初步 C-CHM-10

化疗和肿瘤切除手术没有解决根本原因;身体会在别处重新启动它的“防御计划”,因此应避免这些治疗。

安全提示: 请勿为了饮食疗法而拒绝、停止或推迟推荐的癌症治疗(手术、化疗、放疗、激素治疗或靶向治疗)。对于可治愈的癌症,用替代疗法取代标准治疗与明显更高的死亡风险相关(I-CHM-03、I-CHM-04),即使仅推迟四周也与更高的死亡率相关(I-CHM-07)。远期不良反应确实存在,可通过癌症幸存者随访照护和心脏肿瘤学照护加以处理;请与负责治疗的肿瘤团队讨论。营养方案可在治疗的同时与肿瘤团队一起调整。本页不提供个体化医疗建议。
简而言之: 该说法错误:随机对照试验表明,手术联合化疗或放疗可以减少远处复发和死亡;没有证据表明身体会因为治疗而在别处“重新启动”癌症。
结论: 该说法错误:随机对照试验表明,手术联合化疗或放疗可以减少远处复发和死亡(例如,胰腺癌术后化疗使5年生存率提高了一倍,I-CHM-120);没有证据表明身体会因为治疗而在别处“重新启动”癌症。

Chemotherapy has to reach the whole interstitium and kills cells again, so the cancer becomes more aggressive and appears in places that cannot be controlled.

Then the tumour surgeons: the tumour surgeon, poor thing, does not understand what tumours are; he goes in to remove the tumour, which is none of his business, and clears out the lymph nodes and glands.

科学评估

错误 – 该说法与可靠证据相矛盾。

证据确定性: 高 – 进一步研究极不可能改变该评估。

1. 说法是什么?

Surgery/chemotherapy are futile because cancer is a defensive plan that will reappear elsewhere.

2. 哪些内容可证实是正确的?

Treatment does not remove all risk factors (e.g., continued smoking), and some cancers recur despite treatment; recurrence comes from residual or micrometastatic disease.

3. 哪些内容是错误或夸大的?

Recurrence is not an inevitable 'reactivation'. Radiotherapy after breast-conserving surgery reduced 10-year recurrence from 35.0% to 19.3% (I-CHM-02); chemotherapy reduces breast-cancer mortality by about one-third (I-CHM-01); delays of four weeks raise mortality (I-CHM-07); alternative-only care had HR 2.50 for death (I-CHM-03).

4. 哪些内容仍不明确?

There is a kernel of truth in the related transcript statement that chemotherapy can make cancer more aggressive: in mouse models and in residual human breast tumours after neoadjuvant chemotherapy, chemotherapy increased markers of cancer-cell dissemination (TMEM) and promoted metastasis in mice (I-INTB-04). This is a preclinical and surrogate-marker finding; it does not outweigh the reduction in breast-cancer mortality shown in randomised trials (I-CHM-01).

5. 哪些研究支持该说法?

Elawady's videos express the same idea (see alt_sources).

6. 哪些研究与该说法相矛盾?

I-CHM-01, I-CHM-02, I-CHM-03, I-CHM-07; I-CHM-120 (adjuvant gemcitabine vs observation: 5-year survival 20.7% vs 10.4%); I-CHM-102 (postmastectomy radiotherapy reduced overall recurrence and breast-cancer death); I-CHM-101. Mixed: I-INTB-04 (mouse dissemination markers, no human outcome data).

7. 对德国和欧洲而言情况如何?

Standard care is surgery plus risk-adapted adjuvant therapy.

8. 关于埃及的已知情况是什么?

Same.

9. 合理的实际结论是什么?

请勿拒绝或推迟有指征的手术或全身治疗。

Randomised evidence shows adjuvant chemotherapy and radiotherapy reduce recurrence and death; replacing or delaying treatment is associated with higher mortality.

哪些证据支持该说法?

  • Chemotherapy can activate tumour 'exit doors' in mice

    Karagiannis GS et al.. Sci Transl Med 2017 · PMID 28679654 · DOI 10.1126/scitranslmed.aan0026 动物研究全文,含结构化偏倚风险评估

    In mice, neoadjuvant chemotherapy increased markers of tumour-cell dissemination; in 20 patients, a dissemination-related marker rose after chemotherapy.

    原始文献

哪些证据不支持该说法?

总体证据说明了什么?

基于上述研究的编辑评估——其本身并非研究结果。

哪种观点有更好的证据支持?

Adjuvant chemotherapy and radiotherapy after surgery reduce distant recurrence and death; there is no evidence of a 'reactivation elsewhere' that cancels the benefit.

为什么有些研究权重更大

Randomised trials with distant recurrence and survival outcomes are decisive; a mouse dissemination signal cannot outweigh human survival data.

因果关系是否已确立? 是,已确立 Randomised comparisons.

仍存在的不确定性

Treatment-induced dissemination signals (I-INTB-04) deserve research but are not reflected in human outcomes.

合理的结论

False.

为什么研究结果看起来互相矛盾?

I-INTB-04 (dissemination markers after chemotherapy in mice) versus randomised trials (fewer distant recurrences): the biomarker signal is real in models but the net clinical effect in humans is fewer metastases and deaths.

通俗解释

该档案网站说,Diaa 医生告诫人们不要接受化疗和手术,因为身体只会在别处再长出肿瘤。大型研究显示的结果恰恰相反:手术后,放疗能使复发的机会减半,化疗能使死亡的机会降低约三分之一。拒绝或推迟这些治疗的人死亡更多。

    Test whether chemotherapy promotes metastasis

    研究是如何开展的?

    Mouse models and human residual tumour tissue

    研究了多少人、动物或样本?

    Mice (about 11 per group) and 20 patients with residual tumour after chemotherapy

    实际发现了什么?

    More TMEM activity and metastasis in mice; higher TMEM scores in humans

    观察到的效应有多大?

    2-3-fold higher TMEM score and about 2-fold more circulating tumour cells in mice; TMEM score increased in all 20 patients (no outcome data)

    研究结果对日常生活意味着什么?

    Chemotherapy can have unwanted biological effects, which researchers try to block with added drugs.

    该研究有哪些局限?

    Mainly mice; human part small, selected and without outcome data; authors hold a related patent

    它对 Elawady 的具体说法说明了什么?

    Partly supports 'chemo makes cancer more aggressive' as a biological possibility; does not show worse survival.

    研究结果是否适用于德国和欧洲?

    Moderate

    从该研究中明确不能得出什么结论?

    Cannot conclude that chemotherapy shortens life or should be avoided.

地区背景

德国 / 欧盟

Standard care is surgery plus risk-adapted adjuvant therapy.

埃及

Same.

在我的国家适用什么?

一般科学评估

错误 该说法错误:随机对照试验表明,手术联合化疗或放疗可以减少远处复发和死亡(例如,胰腺癌术后化疗使5年生存率提高了一倍,I-CHM-120);没有证据表明身体会因为治疗而在别处“重新启动”癌症。

该说法涉及生物学或医学关系。上述科学评估不论在哪个国家都适用;各国食品数据不会改变这一评估。
