CTC monitoring, targeted therapy can lead to remission

Cancer has been a growing concern since President Richard Nixon declared war on cancer in 1971. According to the American Cancer Society, more than 8 million people die from cancer every year and that number has been projected to increase to 13 million by the year 2030 worldwide. [2] Of those deaths, more than 90 percent are the result of cancer metastasisThe spread of cancer cells from the place where they first formed to another part of the body. In metastasis, cancer cells break away from the original (primary) tumor, travel through the blood or lymph system, and form a new tumor in other organs or tissues of the body. The new, metastatic tumor is the same type of cancer as the primary tumor. For example, if breast cancer spreads to the lung, the cancer cells in the lung are breast cancer cells, not lung cancer cells.. [3]

In order to treat cancer, most physicians bombard the patient with various drugs using different treatment methods. The most common conventional cancer treatments include chemotherapy, radiation, and surgery. Cytotoxic chemotherapy is a form of cell cycle dependent therapy that kills cancer cells by interfering with different phases of the cell cycle. In fact, most chemotherapy agents affect the M-phase of the cell cycle by inhibiting microtubule function, DNA synthesis, or protein function. [5]

Although these treatments may be beneficial, they are hardly cancer cell specific. Chemotherapy agents can also bind to healthy cells and induce apoptosisA type of cell death in which a series of molecular steps in a cell lead to its death. This is one method the body uses to get rid of unneeded or abnormal cells. The process of apoptosis may be blocked in cancer cells. Also called programmed cell death.. One of the most common side effects of chemotherapy is hair loss, which is caused by the interruption of cell division in hair cells.Radiation is another form of cancer treatment that eliminates cancer cells through exposure to strong electromagnetic wave particles. The wave particles disrupt the genetic makeup of cells and inhibit their growth and division processes. [1]

Lastly, surgery is a form of treatment that surgically extracts cancer cells them from the primary cancer site. Although these procedures are usually successful in removing initial cancer, ultimately, these methods do not prevent cancer reoccurrence and metastasis. [12]

Circulating Tumor Cells (CTCs), Circulating Stem Cells (CSCs)

One of the least studied aspects of cancer is Circulating Tumor Cells (CTCs). CTCs are cancer cells that are shed from the primary tumor and enter the circulatory system through the blood stream. Thomas Ashworth, an Australian pathologist, first proposed the concept of CTCs in the 19th century. At the time, Ashworth successfully discovered CTCs in a man who was diagnosed with metastatic cancer.

From this identification, Ashworth was able to hypothesize that mobilized cancer cells can play a significant role in cancer metastasis. In other words, cells that shed off from the original cancer site can travel into the bloodstream and cause the same tumor to be formed elsewhere in the body. These findings largely alarmed the scientific community; however, limitations in medical technology hindered the ability to confirm the presence of these cells. [7] More than 140 years later, research in the field has finally been able to confirm what Ashworth proposed more than a century ago.

CTCs often are overlooked in cancer detection process because they are small microscopic cells that are extremely hard to detect. Without the proper medical technology, CTCs and CSCs might as well be scientifically non-existent. Most physicians spend a majority of the time ordering MRIs, PET scans, CT scans, and tumor markers.

Although, these types of tests are effective in detecting tumors, they do not detect circulating cancer cells. R.G.C.C., a research laboratory in Greece, specializes in the detection of circulating tumor cells in the blood. CTCs can be observed in the peripheral blood of cancer patients at relatively low concentrations. Because these cells are found at a much smaller ratio, in comparison to the size of a tumor, highly sensitive and specific technology is required for the detection of CTCs.

How Circulating Tumor Cells (CTCs) and Circulating Stem Cells (CSCs) are derived.
How Circulating Tumor Cells (CTCs) and Circulating Stem Cells (CSCs) are derived. Cancer stem cells, like all other stem cells, begin in an undifferentiated state. Once a signal is received, CSCs undergo a process of cell differentiation to become differentiated cancer cells, which ultimately leads to tumor formation. [4]

The general biological mechanism behind the differentiation of CTCs and CSCs can be seen. Like almost all stem cells, CSCs must receive a signal to undergo cell differentiation. Once the cancer cell has been differentiated, it can grow and proliferate to produce even more cancer cells. [4] The mechanism of cancer stem cell differentiation what leads to tumor formation.

How to detect CTCs and CSCs

The detection of circulating tumor cells in the blood can be highly beneficial in preventing cancer onset, reoccurrence, and metastasis. Currently, the most common types of CTC detection technology include immunocytochemistry, reverse-transcription polymerase chain reaction (RT-PCR), and flow cytometry. [8]

At our medical facility, Cancer Center for Healing, we use CTC to monitor treatment progression in cancer patients. Blood samples are sent directly to R.G.C.C., where researchers are able to identify the number of cancerous cells present in 1 mL of blood. As of recently, only a CTC reading of zero has been associated with being in a state of remission or being cancer free. [4]

Chemotherapy misconceptions

A common misconception with CTC readings is that treatments like chemotherapy, surgery, and radiation are able to lower CTC counts and cure the patient of cancer; however, chemotherapy has actually been shown to increase CTC counts. [5] Although chemotherapy is an effective agent to initially reduce tumor size, ultimately, residual CTCs and CSCs can regenerate and cause tumor regeneration. The regeneration of cancer cells after remission is known as cancer relapse.

The common misconception is that treatments like cytotoxic chemotherapy can induce apoptosis in all cancer cells. However, chemotherapy actually increases the chances of cancer reoccurrence by creating chemo-resistant CTCs and CSCs. [4]

Just as bacteria have been evolving to develop antibiotic immunity, cancer cells have been evolving to become chemotherapy resistant. Although chemotherapy agents are administered at extremely high doses, there is no guarantee that all cancer cells are eliminated after multiple rounds of treatment.

Remaining CTCs and CSCs can become dormant for long periods of time, but ultimately resurface with a vengeance. New chemo-resistant cancer cells thrive in immunosuppressed environments and travel through the blood with ease to initiate cancer cell metastasis. [5]

Treatments that effectively eliminate CTCs and CSCs

Patients with high CTC values are viable candidates for Supportive Oligonucleotide Technique (SOT) treatment; however, in order to use this treatment, their tumor burden must be relatively low. SOT therapy uses splice variants from different cancer-associated pre-mRNAs and uses them to induce antagonistic effects that lead to cancer cell apoptosis.

However, these treatments are only effective when the burden of cancer cells is relatively low. SOT treatment is individualized for each patient’s genetic makeup and treatments vary based on the type of cancer. Patients who have been successful in SOT treatment have been able to decrease their CTC values significantly; one patient in particular, who was treated at our facility, was able to decrease his CTC count by 82.8 percent in less than eight months.


The second form of natural treatment includes natural chemotherapy agents, which induce cancer cell apoptosis naturally. Some of these treatments include homeopathy, Vitamin C, ozone therapy, and targeted nutraceuticals. Homeopathy and the Banerji method have shown to be successful in eliminating CTCs and CSCs.

Studies conducted in India show regressions between 22 and 32 percent in the reduction of CTCs. These improvements have been seen in patients with lung, brain, and esophageal cancer in India. Vitamin C is another type of treatment that is converted into hydrogen peroxide, which can be a harmful agent for cancer cells.

Cancer cells also have been shown to thrive in anaerobic environments. Treatments like ozone therapy negatively affect cancer cells by oxygenating them. By doing so, cancer cells are no longer capable of performing anaerobic functions, which ultimately leads to cell death. [5] R.G.C.C. performs a natural sensitivity panel that Dr. Connealy highly recommends to her patients.

The third way in which individuals can fight their cancers naturally is by improving eating habits. Foods like leafy greens, ginger, turmeric, blueberries, Genistein, cruciferous vegetables, grapefruit, lavender, etc. contain an abundance of enzymes that aid the body’s ability to combat cancer cells.


Did You Know

The Banerji Protocols

The concept of specific homeopathic medicine for a disease based on symptoms was first perceived and practiced by Dr. Pareshnath Banerji. In the Banerji Protocols of treatment, mixtures of remedies or frequent repetitions of the remedies are used when required. This is not practiced in classical homeopathy. The combination of two potentized medicines mixed for special advantages in treatment so that the aggravation due to drugs can be checked, side effects of the medicines can be abated, quick and uneventful recovery can be ensured in a much shorter time.

The triple threat

  • Toxic Environment
  • Toxic Body
  • Toxic Mind

The human species has thrived and survived for thousands of centuries by using its innate ability to heal itself. Today, that process has been hindered by the increased amount of exposure to toxic chemicals in the environment.

Electromagnetic radiation, genetically modified food, and air pollution are some of the many ways our bodies have been put under increased environmental stress. Epigenetics plays a large role in gene modification.

A review of a study published in the Oxford Journal states that global environmental changes and changes in the epigenetic landscape are hallmarks of cancer. Epigenetic changes include DNA methylation, histone modification, nucleosome positioning, and the addition of non-coding RNAs. Any of these genetic modifications can be detrimental to the normal function of the cell cycle. [11]

As discussed earlier, deregulation of the cell cycle is what ultimately causes cancer. Signs of elevated CTCs and even cancer are signs that your body is suffering from a much greater illness or chemical imbalance. Increased sugar intake, bad eating habits, increased stress, irregular sleep cycles, and increased depression or emotional trauma, are all exposures that increase the risk of developing cancer.

Individuals must learn to view their bodies as one entity, not separate parts that make up a whole. One must learn to find the root of the problem and treat the symptoms from the inside out. For example, if a patient is experiencing chronic inflammation in the intestines it would be counterproductive to only look at gastrointestinal tract. In fact, by only treating the symptoms doctors are completely avoiding the greater “underlying” issue.

A knowledgeable physician would look at the patient’s eating habits, stress levels, nutritional deficiencies, etc. It is only when you have all pieces of the tapestry that you are able to put together the pieces and look at the product as a whole. A similar analogy can be applied to cancer; it would be ineffective to bombard the tumor with multiple rounds of chemotherapy and not check for remaining circulating tumor cells in the bloodstream.

Without checking remaining CTCs, cancer could very easily metastasize to multiple regions of the body and leave the patient completely helpless. A good physician is a wise physician. Therefore, physicians must learn to make wise choices if they truly want to earn the faith, trust, and hope of their patients.

The discovery of circulating tumor cells has revolutionized the field of cancer medicine. With this discovery, physicians and researchers are able to diagnose the possible presence of cancer before evidence of a tumor, prevent cancer metastasis, and confirm cancer cure and remission. Simply put, cancer can now be detected through the simplicity of a single blood test and cancer remission is possible with CTC monitoring and targeted treatments.
