Case Studies

Confidence in our CAAT Protocol

At the A.P. John Institute for Cancer Research, we are confident of CAAT's capability of helping cancer patients lead a longer and better quality of life. CAAT's effectiveness in treating cancer has helped people with many different types of cancer. In this section, you'll read some vignettes about actual patients of the Institute and how the CAAT protocol made a significant difference in their lives. The case history blurbs of CAAT patients summarize the patients' cancer conditions and the results of the treatment. Every patient at the completion of CAAT returned to a personalized nutritious diet that included the use of the recommended supplements.


Brain Stem Cancer

Jill C., 32 years

Condition and Treatment
Jill was diagnosed with recurring brain stem cancer. She was treated with chemotherapy and radiation and enrolled in CAAT for seven months.

After the first three months, her tumor shrank 35 percent. At the end of six months, an MRI scan revealed no scar tissue or tumor in the brain stem area. Her neurological problems were reduced 80 percent.

Breast Cancer

Marilyn P., 64 years

Condition and Treatment
After being diagnosed with recurrent breast cancer, Marilyn found her cancer had metastasized to both lungs. She enrolled in CAAT for eight months while continuing chemotherapy.

The tumor in Marilyn's left lung totally disappeared. A small tumor, 0.2 inches (0.5 cm) in diameter, was removed from her right lung.

Gall Bladder Cancer (Cholangiocarcinoma)

Don W., 57 years

Condition and Treatment
After being diagnosed with cholangiocarcinoma, Don had his gall bladder removed and his small bowel connected to his bile duct. He was not treated with chemotherapy because he was considered terminal. Not willing to give up, Don enrolled in CAAT for nine months.

Blood tests show normal blood markers, including bilirubin and alkaline phosphatase levels. Don's CAT scan showed no evidence of liver tumors.

Colon Cancer

Paul V., 66 years

Condition and Treatment
Paul was diagnosed with recurring colon cancer with metastases to the liver and several areas in his bones. He enrolled in CAAT for seven months while continuing his chemotherapy.

Paul's CAT scan revealed the tumor in his liver had shrunk 35 percent and that the bone tumors totally disappeared.


Mary H., 63 years

Condition and Treatment
In 1994, Mary was diagnosed with intermediate-grade lymphoma. She was successfully treated with conventional medicine, but five years later she had a recurrence. Mary did not respond to chemotherapy or radiation for tumors in the chest and groin areas. She decided to enroll in CAAT.

An 0.8-inch (2-cm) tumor under Mary's arm totally disappeared.

Non-Hodgkin's Lymphoma

Peter A., 44 years

Condition and Treatment
Peter was diagnosed with non-Hodgkin's lymphoma. He was treated successfully with both chemotherapy and radiation, but had a recurrence that failed to respond to conventional medicine. Peter then enrolled in CAAT for six months because of tumors in the neck and groin areas. Some were as large as 1.6 inches (4 cm) in diameter.

All of his tumors disappeared and all his tumor markers are now within normal range.

Ovarian Cancer

Ruth C., 72 years

Conditions and Treatment
Ruth was diagnosed with ovarian cancer. She underwent surgery, but part of the tumor could not be removed. Two months after chemotherapy, she decided to enroll in CAAT and to discontinue her chemotherapy.

After six months, a CAT scan and ultrasound found no evidence of cancer in her body. Her blood chemistry remains within the normal range.

Pancreatic Cancer

Joe E., 67 years

Condition and Treatment
Joe was diagnosed with pancreatic cancer. Tumors metastasized to his kidneys and spinal cord. Doctors discontinued chemotherapy because the tumors just continued to grow. Joe enrolled in CAAT for eight months.

Joe's CAT scans show no evidence of tumor growth.

Prostate Cancer

John L., 76 years

Condition and Treatment
John was diagnosed with cancer of the prostate. He received chemotherapy until his cancer spread to his pelvic bone and his prostate-specific antigen (PSA) level increased to 15. Because chemotherapy did not appear to be helping John's cancer, his doctors discontinued it. John then enrolled in CAAT.

John's most recent CAT scan shows no cancer in his bones and his PSA level dropped to 7. John continues CAAT and is in his ninth month.


Blair M., 68 years

Condition and Treatment
Blair was diagnosed with cancer of the prostate. His PSA level was 15. He was treated with flutamide (Eulexin®) and enrolled in CAAT for six months.

Blair's PSA level plummeted to 0.8, and all tumor markers became normal.

It is important to note that every patient was treated with CAAT for 6 to 9 months and then returned to a regular nutritious diet that included the use of the recommended supplements.
