Cancer 101
It is now widely accepted that all cancers
are caused by adult stem cells (or cells with
stem-cell like properties).
www.ctoam.com
What is an adult stem cell?
• The progenitor (originator) of a group of cells of a specific type
• Occur in roughly 1 out of 6 million body cells.
• Used to repair and replace body cells.
www.ctoam.com
What is an adult stem cell?
• Exist in regions referred to as stem cell niches, where they remain in a dormant state (quiescence) until activated.
• Each type of tissue contains it’s own stem cell niche.
www.ctoam.com
What is an adult stem cell?
• All stem cells have unique features that allow them to avoid destruction during treatment.
• However, it is their ability to exist in a dormant state (quiescence) until activated, that is currently inhibiting standard treatments.
www.ctoam.com
The 2 stages of stem cell activation
There are two key stages of stem cell
activation:
1. Proliferation.
2. Differentiation.
www.ctoam.com
The 2 stages of stem cell activation
In The Proliferation Stage:
The stem cell makes multiple copies of itself.
In The Differentiation Stage:
The multiple copies are converted into the
required cell type and given a Hayflick
number.
www.ctoam.com
The 2 stages of stem cell activation
• The Hayflick number is the number of times a normal cell will divide before it stops and dies.
• The important point here is that once a cell has differentiated, it has a finite lifespan.

Stem cell life cycle
www.ctoam.com
There are two imports points here:
1. A stem cell makes an exact copy of itself, which remains dormant in the stem cell niche.
2. A stem cell also produces a large amount of progenitor cells, which then differentiate into the required type of cells.
Stem cells and cancer
The problem with stem cells is that sometimes, due to mutations, a stem cell is not provided with the cues for differentiation and it gets stuck in a never ending cycle of proliferation, making many copies of itself.
This is what we call cancer.
www.ctoam.com
Genes and cancer
There are two key types of genes involved
in cancer:
1. Oncogenes.
2. Tumor suppressors.
www.ctoam.com
Genes and cancer
Oncogenes (tumor causing genes):
1.Cause proliferation.
2. Are turned on (expressed) or over-expressed
in cancers.
3. Are mutated in such a way that causes them
to stay on. www.ctoam.com
Genes and cancer
Tumor suppressors (cancer preventing genes):
1. Initiate differentiation.
2. Are inhibited or under-expressed in cancers.
3. There are common mutations and deletions of
tumor suppressors that occur in specific forms
of cancer.www.ctoam.com

Why is this important?
There are hundreds of documented oncogenes and tumor suppressor genes in your body.
Only four of these genes need to be altered or mutated for cancer to develop.
www.ctoam.com
Why is this important?
Therefore, there are many 1000’s of possible combinations of gene alterations that can lead to cancer in each individual case. It is not the same for every person.
This is why success rates for treatment can vary so greatly from one person to another.
www.ctoam.com
Development of cancer
Now let’s explore how cancer develops once the unregulated proliferation of stem cells has begun.
www.ctoam.com
Metastasis
When a cancer cell is stuck in proliferation
and hasn’t differentiated, it can live almost
anywhere in the body (metastasize)
But, how is it that cancer cells travel throughout
the body?
www.ctoam.com
Angiogenesis and metastasis
Cancer cells are constantly growing and therefore, need to consume a lot of resources. In other words, they require their own blood supply.
Angiogenesis is a process that cancers use to recruit their own blood vessels in order to enable their continued growth.
www.ctoam.com
Angiogenesis and metastasis
The process of angiogenesis is controlled by oncogenes and tumor suppressor genes.
Oncogenes are responsible for the development of angiogenesis while tumor suppressor genes inhibit it.
www.ctoam.com
Epithelial To Mesenchymal Transition (EMT)
Epithelial cancer stem cells interact with a type of cell derived from bone marrow called mesenchymal stem cells in a process called epithelial to mesenchymal transition.
www.ctoam.com
Epithelial To Mesenchymal Transition (EMT)
In the EMT process, cancer stem cells send out signals that attract the mesenchymal stem cells from the bone marrow into the tumor where these cells interact and stimulate the growth of cancer stem cells.
Also provides the primary tumor cells (epithelial) to metastasize to bone.
www.ctoam.com
Epithelial To Mesenchymal Transition (EMT)
The process of EMT is controlled by oncogenes and tumor suppressor genes.
Oncogenes are responsible for the development of EMT while tumor suppressor genes inhibit it.
www.ctoam.com
Summary
• Stem cells remain dormant until activated.
• Cancer is a disease of the stem cells caused by reduced differentiation and increased proliferation.
www.ctoam.com
Summary
• The recruitment of blood vessels (angiogenesis) allows the tumor to grow and to metastasize.
• EMT allows the primary tumor cells to metastasize to bone.
• Proliferation, differentiation, angiogenesis and EMT are all controlled by genes.
www.ctoam.com
The standardized approach to cancer treatment
utilizes the following three techniques:
1. Surgery: Removes diseased tissues.
2. Radiation: Creates DNA mutations in rapidly dividing cells.
3. Chemotherapy: Chemical interference of rapidly dividing cells.
www.ctoam.com
Standard treatment methods
Limitations of surgery
www.ctoam.com
Surgery is localized:
• Limited to treatment of localized disease.
• Potential to miss stem cells, cells that are in pre-cancerous stages, or cells that have already metastasized.
Limitations of radiation
Radiation is localized:
• Non-selective, affects all rapidly dividing cells and is very toxic.
• Only affects active cells during course of treatment (not dormant cancer causing stem cells).
www.ctoam.com
Limitations of radiation
Radiation is localized:
• Angiogenesis (cancer cell recruitment of blood vessels) occurs directly after treatment.
• Radiation can create new DNA mutations that may lead to new cancers.
www.ctoam.com
Limitations of chemotherapyChemotherapy (generalized):
• Non-selective, affects all rapidly dividing cells and is very toxic.
• Only affects active cells during course of treatment (not dormant cancer causing stem cells).
www.ctoam.com
Limitations of chemotherapy
Chemotherapy (generalized):
• Angiogenesis occurs directly after treatment.
• Chemotherapy can create new DNA mutations that may lead to new cancers.
www.ctoam.com
Radiation and chemotherapy
The main difference between radiation and chemotherapy is that radiation is used locally and limited to specific regions of the body, while chemotherapy affects all of the cells in the body.
www.ctoam.com
Additional concerns: Surgery & Radiation
In order for surgery and radiation to be effective, the following concerns need to be addressed:
• Doctors need to target the stem cell niche as well as the malignant tissue (tumor).
• Doctors need to ensure they have accurate imaging prior to surgery and treatment to differentiate between normal and tumor tissues.
www.ctoam.com
Making informed choices: Imaging
PET/CT
• Combines CT imaging with positron emission tomography.
• Shows biological activity within organs and detects cancer in the earliest stages.
• Uses a cancer-specific glucose solution and a radioactive tracer agent that lights up cancerous hot spots.
www.ctoam.com
Imaging: PET-CT
According to the BC Cancer Agency;
In 87 % of cases in which a patient has had a PET-CT scan, the results of the test lead to changes in the initial decisions made by oncologists for planned cancer treatment.
www.ctoam.com
Making informed choices: Imaging
Imaging: PET-CT
In other words, without a PET-CT scan, current detection methods are only accurate 13% of the time!
PET-CT not only ensures proper targeting of the tumor during surgery and radiation treatments, it helps avoid over-treatment or under-treatment.

CT Alone PET/CT
www.ctoam.com
Additional concerns: Chemotherapy
Issues:
• In order for chemotherapy to be effective, we need to accurately determine the dosage and combination of drugs that provides maximal benefits with minimal side effects.
• Need to affect stem cell niche as well as malignant tissue.
www.ctoam.com
Making informed choices: Diagnostics
Chemotherapy Sensitivity Tests:
• Performed on a patient’s tumor sample to identify personalized dose and drug combinations (optimized chemotherapy).
• Allows for lower doses, less side effects, and faster recovery times
www.ctoam.com
Clinical trials:
• Clinical trials represent leading-edge medical science. However, less than 5% of adults diagnosed with cancer each year are enrolled in clinical trails.
• While there are a number of various treatment approaches being offered through clinical trials, 8 out of 10 patients are not aware that this is a viable option for them.
www.ctoam.com
Benefits of clinical trials
• In order to be offered to the human population, each clinical trial must show that the approach being tested is superior to standard treatment.
• Patients are also provided with superior imaging and diagnostics not typically offered in public medical facilities.
www.ctoam.com
• They do not replace standard treatment, they are a form of adjunct therapy, and as such are offered as an additional treatment to standard treatment.
• In most clinical trials the standard treatment is typically used in place of the placebo (control group).
Benefits of clinical trials
www.ctoam.com
• Clinical trials are typically FREE.
• But best of all, their success depends
on your survival!

Nutraceuticals
A nutraceutical is a naturally occurring component of a food group that has scientifically proven cancer fighting activity.
www.ctoam.com
Nutraceuticals
Nutraceuticals can be used to regulate cancer-specific pathways and genes during and between treatment regimes.
www.ctoam.com
Nutraceuticals
Nutraceuticals have the ability to continually regulate cancer causing stem cells, unlike toxic drug based approaches.
Nutraceuticals can also enhance cancer cell sensitivity to standard chemotherapy and radiation therapy, improving treatment outcomes.
www.ctoam.com
Nutraceuticals
Nutraceuticals are inexpensive and non-toxic.
Nutraceutical combinations can be used to create a personalized diet based on the unique genetic signature of your cancer.
You can start today.
www.ctoam.com
Nutraceutical based gene targeting: PTEN
PTEN is a tumour suppressor gene that normally initiates stem cell differentiation.
PTEN is down-regulated (diminished) or mutated in a variety of cancers.
www.ctoam.com
Subtle variations in PTEN levels have been proven to determine cancer susceptibility.
In other words, the amount of PTEN in a cell can determine susceptibility to certain cancers.

Nutraceutical based gene targeting: PTEN
Even a small decrease in PTEN levels can create a greater chance of cancer.
More importantly, even a small increase in PTEN levels can reduce your susceptibility to certain cancers!
www.ctoam.com
Nutraceutical based gene targeting: PTEN
There are a variety of easily accessible Nutraceuticals that can reactivate PTEN:
• Sulforaphane (broccoli).
• Genestein (soy).
• Resveratrol (red wine).
• EGCG (green tea).
• Curcumin (tumeric).
www.ctoam.com
Nutraceutical based gene targeting: PTEN
One of the largest hurdles in the therapeutic
use of nutraceuticals is their low bioavailability.
The bioavailability of a nutraceutical refers to
its ability to remain in the body at a
concentration that has cancer fighting activity.
www.ctoam.com
Nutraceutical based gene targeting: Concerns
Bioavailability Example: Curcumin Absorbance
www.ctoam.com
A component of pepper named piperine greatly increases the oral bioavailability of curcumin.
Piperine increases the absorbance of curcumin by 2000 %.
Nutraceutical: Issues
Factors affecting the outcome of nutraceutical
clinical trials:
• Variations in the amount of the nutraceutical used in the different clinical trials.
• The amount and form of the nutraceutical differs between the strain and type of plant that it was obtained from.
