Treatment for Colon Cancer with Stem cell transplants

CAR-T Cell Immunotherapy & Stem Cells for Colorectal Cancer

Colorectal cancer also known as rectal cancer or bowel cancer occurs when abnormal cells grow out of control in the large intestine or rectum and form malignant tumours. Most colorectal cancers arise in the lining of the colon and rectum and form malignant tumors from benign polyps through different genetic mutations. Polyps are benign growths that are usually harmless. However, if it’s not detected and undiagnosed for a long time, it may become malignant.

What is Colorectal cancer?

Colorectal cancer includes a colon or rectal cancer, depending on the location and origin of the cancerous tumours. Colorectal cancera is one of the most common types of cancer in the world and the second leading cancer killer.

Is Bowel cancer hereditary?

Nearly one-third of all colorectal cancers are believed to be caused by genetics and family history. The three most common genetic disorders associated with colorectal cancer are:

  • MYH gene mutation associated polyposis – is caused by mutations in the MYH gene, resulting in the appearance of 10-100 more colorectal cancer polyps, which then become malignant tumors.
  • Familial adenomatous polyposis (FAP) – Causes a large number (100–1000) of adenomatous polyposis, gland-like growths in the lining of colorectal cancer.
  • Hereditary Non-Polyposis Colorectal Cancer (HNPCC ) (Lynch Syndrome) – Causes a mutation in a gene responsible for protecting cells from abnormal growth and transformation into cancer cells.


Staging of Colorectal Cancer

Colorectal cancer is staged and classified using the TNM system, which helps doctors understand your cancer.[1] TNM is:

  • Tumour:  The extent to which a tumour affects the wall of the bowel or other tissues, for example, whether it has passed through the wall of the rectum or colon.
  • Nodes: If nearby lymph nodes are affected.
  • Metastasis: The overall extent to which cancer has spread to other organs in the body.
  • Colorectal cancer is classified into five stages (stages 0 to 4).

Signs and symptoms of colorectal cancer

Not everyone will experience symptoms of colorectal cancer. However, some common symptoms include:

  • Changes in bowel habits
  • Sudden weight loss
  • Lump or pain around the anus
  • Diarrhoea, constipation, loose stools, or mucus
  • Stool with bright red or dark red blood
  • Frequent tiredness and shortness of breath
  • Unexplained anaemia (low iron)
  • Abdominal discomfort or bloating


Diagnosing Colorectal cancer

Regular cancer screenings are essential for the early detection of bowel cancer in people with no signs or symptoms. The Regeneration Center recommends annual cancer screenings for all persons aged 48 to 80. Tests should include faecal occult blood tests to detect any blood particles (a potential symptom of colorectal cancer) in the stool.

For patients who have bowel cancer symptoms or are not fully diagnosed yet a comprehensive colorectal cancer screening will be necessary and can be done in Bangkok or outside of Thailand.

Standard bowel cancer tests include:

Colonoscopy: A colonoscopy exam is a procedure in which a tube with a camera attached to the rectum is inserted into the rectum to examine the entire length of the colon. Colonoscopy is most commonly used to diagnose severe iron deficiency anaemia and patients with mild bowel symptoms. This test has both diagnostic and therapeutic uses. It can take tumour biopsies, stop tumour bleeding, and place stents to relieve blockages.

CT Scan or Computed Tomography Colonography – Computed Tomography Colonography, also known as virtual colonoscopy. It provides a less invasive examination for those who cannot undergo colonoscopy by utilizing 3D images of the large intestine and rectum produced by a computed tomography scanner. However, colonoscopy tests may still be required if a biopsy is required. If the CT Scan results lead to a diagnosis of ulcerative colitis or bowel cancer, additional tests are usually done to assess whether cancer has spread beyond the colon or rectum.[3]

Other checks can include:

  • Stool DNA Test
  • Fecal occult blood test (FOBT)
  • Fecal immunochemical test (FIT)
  • Magnetic Resonance ( MRI scan )
  • Positron scanning
  • Blood tests
  • Genetic cancer screening

Treatment of  Colorectal Cancer (Non-Metastatic)

There are many treatments available for colorectal cancer, and our treatment plans are customized to you and your cancer. Immunotherapy treatment options for colorectal cancer depend on the cancer type, tumour size, stage, location, health, and treatment preferences. One of the most common traditional treatment for colorectal cancer is surgery, depending on the cancer stage. It can be used with chemotherapy, radiation therapy or targeted therapy.

Traditional Treatments for Rectal Cancer

Cancer Surgery – A surgical procedure can be used to treat colorectal cancer is known as a colorectal resection (colectomy). Colon resection surgery requires removal of all or  immuno-treatment-colon-cancerpart of the colon.

Two techniques for colectomy surgery include:

  1. Laparotomy – a surgeon will make a large incision in the abdominal wall to remove part of the colon
  2. Laparoscopic surgery – a less invasive type of colectomy surgery that only requires 4 to 5 small incisions to cut through the colon
    Although both techniques effectively remove tumours, laparoscopic surgery is now the routine technique for colorectal resection. It reduces bleeding, postoperative pain and wound infection and allows for faster recovery of bowel and body function after surgery and shorter hospital stays [4].

Other treatments include:

  • Radiation therapy – using radiation to target and destroy cancer cells
  • Chemotherapy – the use of drugs to kill cancer cells
  • Targeted therapy – a therapy designed to destroy cancer cells while leaving healthy cells intact

With or without conventional therapies, With or without metastasis our cancer remediation programs offers patients the highest chances for success.[5]

Traditional cancer treatments such as chemotherapy & radiation therapy expose humans to significant side effects and toxicity. Over time, the traditional methods have not changed but the cancer cells themselves have evolved making them more resistant to the chemicals and rendering these traditional therapies ineffective especially in later stages of kidney cancer, lung cancer, prostate cancer pancreatic adenocarcinoma and hepatocellular carcinoma. This evolution of cancer stem cells is what leads to recurrence and allows them to proliferate much more aggressively than before the chemo & radiation therapies began decades ago. Some new pharmaceutical based medications have been developed to effectively target and destroy cancer cells with much less toxicity, but the payloads often don’t reach the intended destinations and are consumed but the patients immune system before it can reach the intended targets and tumors.
