Cancer – Losing the War<\/strong><\/h3>\nLung, liver, stomach, and bowel cancers are the four most common causes of cancer death; and this has remained true since 1975. Infection\u2010associated cancers, including cervix, stomach, and liver are disproportionally prevalent in emerging economies. In contrast, cancers in higher-income countries are strongly associated with lifestyle factors such as smoking, poor diet, obesity, and alcohol intake.<\/span><\/p>\nThe statistics<\/a> <\/span>are depressing. The level of funding for cancer research does not appear commensurate with cancer outcomes. Cancer patients continue to suffer and die at unacceptable rates.\u00a0<\/span>In 2013, this beast took my mother\u2019s life. Since then, my quest to discover the origins and mechanism of cancer has become all-consuming. I refuse to believe that we have lost the war. I prefer to submit that we\u2019ve simply failed to understand the enemy.<\/span><\/p>\nThe art of war is to subdue the enemy without fighting.<\/span><\/p><\/blockquote>\nPerhaps, like type 2 diabetes and heart disease, we have got our understanding of cancer completely wrong. In type 2 diabetes, we have been \u2018treating\u2019 the blood sugar, instead of treating the rising insulin levels and consequent insulin resistance. In heart disease, we have been blaming cholesterol and saturated fat, rather than focusing on what causes the injury to the blood vessels in the first place. <\/span><\/p>\nAll <\/strong>metabolic diseases are on the rise. The rate of rise in middle and lower income countries is even faster than in high-income countries. Cancer rates are rising just as fast. It seems at least probable that it could be a metabolic disease. In fact, many cancers are now included under the umbrella of the \u2018Metabolic Syndrome\u2019.<\/span><\/p>\n <\/p>\n

The Metabolic Syndrome | CANCER INSULEAN<\/p><\/div>\n
<\/p>\n
The Somatic Mutation Theory<\/strong><\/h3>\nThe prevailing understanding of cancer is that it is a genetic disease. This is termed the Somatic Mutation Theory (SMT)<\/strong>, which theorizes that a cell develops mutations (mistakes) that allow it to become cancerous. The SMT premise is that cancer is derived from a single cell that has accumulated multiple random DNA mutations, leading to cell proliferation.<\/span><\/p>\nThis theory birthed an increasingly complicated profile of cancer, with hundreds of \u2018problem\u2019 genes being identified. We now, therefore, think of cancer as a terribly complicated disease; and in so doing, we accept invasive and devastating treatments as an inescapable price to pay. This and many more interventions are performed to accommodate this complexity.<\/span><\/p>\nThere are approximately ten trillion cells in the human body. Throughout life, these cells are assailed with radiation, oxidative damage, viruses and more. Individuals\u2019 own genetic susceptibility, damage from cigarette smoke, lack of physical activity, obesity and aging itself can cause many oncogenes (genes that have the potential to cause cancer) to get activated and many tumour suppressor genes to be inactivated. Yet, according to the prevailing SMT dogma, these cells should lose control and become autonomous. But this does not seem to play out. We do not develop as many cancers as would be expected from the number of harmful mutations. Why is this?<\/span><\/p>\nWhen we think of Cancer, we think of Complexity.<\/span><\/p><\/blockquote>\nIn any case, the SMT paradigm has come to be accepted as self-evident in mainstream medicine. This has led to expensive gene-based research, including identification of genetic mutations, gene editing and development of gene-based therapies. There is an entire industry that has mushroomed from genomic science – an expensive, labour-intensive industry. This would be acceptable, and, in fact, welcomed, were it not for the fact that, across the board, we are losing the war against cancer. <\/span><\/p>\nWe are still treating people with toxic, life-threatening chemotherapy medication. Medication that does not spare healthy cells. All cells suffer, cancerous or not. And the patient suffers. Their hair falls off and ulcers form throughout their gastrointestinal tract, causing painful mouth ulcers, profuse diarrhoea, malabsorption, and everything in between. And this is before infections take hold.<\/span><\/p>\n <\/p>\n
<\/h3>\nThe Current Standard of Care<\/strong><\/h3>\nWe are still significantly compromising quality of life, for the sake of a few extra months of life. We are resigned to the idea that the torture the patients go through is in their best interests, and that there is no possible alternative. We have developed robust protocols to treat the host of side-effects that we anticipate. High-dose chemotherapy protocols damage the healthy bone marrow, rendering the patient anaemic, neutropenic (at risk of infections), and thrombocytopenic (at risk of bleeding).\u00a0 Doctors barely blink when a cancer sufferer requires blood products to stay alive; because this is the \u2018new normal\u2019.<\/span><\/p>\nWe expose patients to radiation, in an attempt to shrink tumours, the treatment of which is a well-recognised carcinogen. By the time most cancer patients start their treatment, they have already been exposed to huge doses of radiation. This comes from multiple X-rays, CT scans, CT guided-biopsies and PET scans that have been done, in an attempt to diagnose the condition. Radiotherapy, which is often required, only adds to this insult.<\/span><\/p>\nA carcinogen is a substance capable of causing cancer in living tissue.<\/span><\/p><\/blockquote>\nApart from the terrible side-effects of most chemotherapy regimens, we prescribe a host of other \u2018supportive medications\u2019, such as steroids. These increase the risk of infections, raise blood glucose and perpetuate insulin resistance. We also, quite often, give low dose antibiotics and antivirals, to protect against opportunistic infections that could kill the very person we are trying to save with the said chemotherapy. Antibiotics, chemotherapy, and radiotherapy are well known to disrupt the gut microbiome<\/a><\/span>, which we are now recognising as a crucial contributor to overall health, with unhealthy gut microbiota being linked to everything from allergies, diabetes and, believe it or not, cancer.<\/span><\/p>\n <\/p>\n
<\/h3>\nA 21st Century Plague<\/span><\/strong><\/h3>\nCancer cases are now at epidemic levels. It is almost certainly a 21st<\/sup> Century plague that is maiming and killing people at a shockingly rapid rate. \u2018Cure\u2019 is often not discussed, particularly with adult malignancies. Your best bet is to be \u2018in remission\u2019, which means that the doctors can no longer detect cancer in your body (with the technology available). You are sent home with 6-monthly follow-ups arranged. To look for cancer regrowth, oncologists must perform a CT scan. This means more radiation exposure, on a 6-monthly or yearly schedule, until remission is attained, or the cancer recurs \u2013 which it often does, as in my mother\u2019s case. <\/span><\/p>\nExactly 5 years after her initial diagnosis, her cancer was back and more aggressive the second time around. She had unrivalled access to world-class doctors and the latest treatments. Nothing worked. 4 months later, she was gone.<\/span><\/p>\nScience evolves by being challenged, not by being followed. We can continue to dive deeper into the \u2018gene hypothesis\u2019, even in the face of abysmal rates of death, or we can change our hypothesis. This means throwing out our current understanding of cancer and starting again. In science, when observations do not fit your hypothesis, it is the hypothesis that needs to change, not the facts. The fact is that there are thousands of genes in a cell, and thousands of mutations (mistakes) can occur. One, or a cluster of genetic mutations can be linked to a certain type of cancer, such as the faulty BRCA1 gene (linked to breast and ovarian cancer). However, having these mutations does not necessarily mean you will develop cancer. Other mutations can also be linked to the very same cancer.<\/span><\/p>\nCausality<\/strong><\/h4>\nIn my article, \u2018Causality\u2019<\/a><\/span>, I discuss the concept of cause and effect, as it relates to the medical field.\u00a0<\/span>Causality is difficult to prove. However, it can be disproven quite easily.\u00a0This is where the\u00a0notions\u00a0of necessity and sufficiency come in.<\/span><\/p>\n\n- Sufficiency \u2013 is the cause is always followed by the effect?<\/span><\/strong><\/li>\n
- Necessity \u2013 does the cause always precede the effect and can the effect occur without the cause?<\/span><\/strong><\/li>\n<\/ul>\n
Let me explain. If it is said that mutation A causes cancer B, in order to disprove the hypothesis, one must find people with cancer B who do not have mutation A.\u00a0This is the concept of \u2018necessary\u2019 \u2013 that the factor is \u2018necessary\u2019 to prove causality. As an example, the BRCA1 mutation is neither necessary nor sufficient, to cause breast cancer. The majority of people with breast cancer do not have this genetic mutation. In addition, having the faulty gene does not guarantee you will get breast cancer.<\/span><\/p>\nTo establish causation, we would need to subject the faulty gene to the\u00a0Bradford Hill criteria<\/a><\/span>. If the strength of association is double, the other eight criteria are worth looking at for potential causation and not just association.<\/span><\/p>\n <\/p>\n
<\/h3>\nSomatic Theory Success Stories<\/strong><\/span><\/h3>\nAPML (Acute Pro-Myelocytic Leukaemia)<\/span><\/strong><\/h4>\nSometimes the gene theory works very well. AMPL is a type of cancer of the white blood cells. Scientists discovered that this cancer is linked to a problem with the Retinoic Acid Receptor<\/a>\u00a0<\/span>alpha (RARA<\/em>) gene. The targeted therapy that was developed is called ATRA (All-Trans Retinoic Acid), and APML responds very well to this treatment. This treatment has revolutionised the management of this disease, which was once considered an acute, fatal illness. We now have very high, 10-year survival rates.<\/span><\/p>\nBut that\u2019s only part of the story. ATRA alone is not enough for many sufferers of AMPL. Many patients who are at risk of recurrence of this disease also need to be treated with chemotherapy and other toxic drugs. The adverse effects of these drugs cannot be underestimated, with many patients dying after succumbing to overwhelming infections, or organ failure, as a direct result of these treatments.<\/span><\/p>\nCML (Chronic Myeloid Leukaemia)<\/span><\/strong><\/h4>\nAnother example is Chronic Myeloid Leukaemia (CML). Glivec (Imatinib) is the world\u2019s most-often prescribed drug for this cancer. It revolutionised the treatment of this disease by targeting the molecular cause of CML.\u00a0Glivec prolongs progression-free survival in most patients. The BCR-ABL fusion gene that is \u2018responsible\u2019 for this cancer is found in most patients with CML. However, it is also found in some patients with other types of acute leukaemia.<\/span><\/p>\nI have recently learned that Glivec<\/a> <\/span>does not alter the cancer cells\u2019 DNA. It works by altering the growth signalling pathways causing glycolytic suppression and increased autophagy. I will be exploring this, in some detail, later in this article.<\/span><\/p>\nGlivec is likely an exceptional case. CML is caused by a single faulty fusion gene. This is unlike most other cancers, which are caused by a multitude of complex interacting genetic and environmental factors, and therefore have many potential targets. Having a single target makes it easier to develop successful treatments. Having multiple targets is a nightmare scenario when it comes to therapeutics.<\/span><\/p>\nA genetic approach seems, to me, like a needle-in-the-haystack approach.<\/span><\/p><\/blockquote>\nSo, it\u2019s not to say that genomic research is completely useless in oncology. That would be a ridiculous position, as it very clearly has its role. Gene mutations have been identified as the cause of\u00a0several non-cancer disorders<\/a>\u00a0<\/span>including sickle cell anaemia, cystic fibrosis, Huntington disease, and haemophilia. These can result from single, multiple, or combined gene mutations, and environmental factors; or by\u00a0chromosome mutation<\/a>\u00a0<\/span>or damage.<\/span><\/p>\n
The statistics<\/a> <\/span>are depressing. The level of funding for cancer research does not appear commensurate with cancer outcomes.
