错误 已被科学证据否定 证据确定性: 高 初步 C-CHM-12

癌症患者不应接受(或应停止)化疗、放疗或生物治疗,而应改为执行 Tayebat 体系;“我们反对‘药’这个词”。

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:没有任何研究表明饮食能取代化疗、放疗或生物治疗,而随机对照试验表明这些治疗能避免死亡,仅采用替代疗法与明显更高的死亡率相关;营养可以在治疗的同时发挥辅助作用,而不能取代治疗。
结论: 该说法错误:没有任何研究表明饮食能取代化疗、放疗或生物治疗,而随机对照试验表明这些治疗能避免死亡,仅采用替代疗法与明显更高的死亡率相关;营养可以在治疗的同时发挥辅助作用,而不能取代治疗。

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?

Rejection of chemotherapy, radiotherapy and biologicals; presentation of patients who refused or stopped chemotherapy as successes.

2. 哪些内容可证实是正确的?

Elawady sometimes said patients decide themselves (P86iybRnOE4: those who want chemo may take it). End-of-life chemotherapy is often not beneficial (C-CHM-07). Side effects are real (C-CHM-01..06).

3. 哪些内容是错误或夸大的?

In curable cancers, refusing chemotherapy, radiotherapy or surgery costs lives: alternative-only treatment HR 2.50 for death (breast cancer HR 5.68) (I-CHM-03); excess mortality with complementary medicine was mediated by refusal of conventional therapy (I-CHM-04); chemotherapy reduces breast-cancer mortality by about one-third (I-CHM-01); childhood ALL survival 90% (I-CHM-05). Even delays matter: in observational data, each 4-week delay (studied range about 4-16 weeks, in patients who were eventually treated) was associated with higher mortality (I-CHM-07); this concerns delay, not refusal. Individual reports of patients doing well without chemotherapy (e.g., after surgery) cannot show that the diet caused the outcome.

4. 哪些内容仍不明确?

The outcomes of the specific patients mentioned in the videos are not verifiable.

5. 哪些研究支持该说法?

None for replacing treatment. The only randomised diet trial found tested nutrition added to chemotherapy (elemental diet during chemotherapy for advanced pancreatic cancer: survival 21.4 vs 12.8 months, small single-centre trial; I-CHM-127).

6. 哪些研究与该说法相矛盾?

7. 对德国和欧洲而言情况如何?

Standard of care in Europe.

8. 关于埃及的已知情况是什么?

Standard of care in Egypt follows the same evidence. At Children's Cancer Hospital Egypt, 72.1% of 14,808 children treated for cancer were alive at 5 years, rising from 69.6% to 74.2% between 2007-12 and 2013-17 (I-CHM-125). In Southern Egypt, 60.5% of families of children with cancer used traditional or complementary remedies, 29% of users as an alternative, and 11.5% of users presented late (I-CHM-126).

9. 合理的实际结论是什么?

绝不要用饮食取代有指征的癌症治疗;营养方面的问题应与肿瘤团队讨论。

研究结果按作者报告呈现。我们的评估见下文。

哪些证据支持该说法?

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?

Replacing indicated chemotherapy, radiotherapy or biological therapy with a diet increases the risk of death; nutrition can support patients alongside treatment.

为什么有些研究权重更大

Randomised trials of treatment vs no treatment and registry data on alternative-only use; no trial tested any diet as a replacement.

因果关系是否已确立? 是,已确立 Randomised treatment benefit; consistent excess mortality with refusal.

仍存在的不确定性

None material for the verdict.

合理的结论

False and potentially life-threatening.

为什么研究结果看起来互相矛盾?

Nutrition trials (I-CHM-127) and treatment trials do not conflict: nutrition was tested as an addition to chemotherapy.

通俗解释

Diaa 医生在多个视频中反对化疗、放疗和生物药物,并把停止化疗的患者当作成功案例来展示。科学证据很明确:对许多癌症而言,这些治疗能大大提高生存的机会。用替代方法取代这些治疗的人死亡要多得多——在一项大型研究中,乳腺癌患者的死亡约为五倍。个人故事无法证明某种饮食治愈了癌症。

地区背景

德国 / 欧盟

Standard of care in Europe.

埃及

Standard of care in Egypt follows the same evidence. At Children's Cancer Hospital Egypt, 72.1% of 14,808 children treated for cancer were alive at 5 years, rising from 69.6% to 74.2% between 2007-12 and 2013-17 (I-CHM-125). In Southern Egypt, 60.5% of families of children with cancer used traditional or complementary remedies, 29% of users as an alternative, and 11.5% of users presented late (I-CHM-126).

在我的国家适用什么?

一般科学评估

错误 该说法错误:没有任何研究表明饮食能取代化疗、放疗或生物治疗,而随机对照试验表明这些治疗能避免死亡,仅采用替代疗法与明显更高的死亡率相关;营养可以在治疗的同时发挥辅助作用,而不能取代治疗。

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。
