What Went Wrong: The Truth Behind the Clinical Trial of the Enzyme Treatment of Cancer

One Man Alone Cover

Silver Award Winner, Independent Book Publishers Association 2013 Benjamin Franklin Awards (Science category)

In What Went Wrong, Dr. Gonzalez chronicles the failure of the National Cancer Institute-NIH funded clinical trial conducted under the auspices of Columbia University, set up to test his nutritional treatment in patients diagnosed with pancreatic cancer. In this first-hand account, Dr. Gonzalez reveals how poor trial design and poor implementation at the highest levels of the academic research world helped undermine this promising project. The book discusses in detail two official government investigations that have confirmed Dr. Gonzalez’s allegations that the study was not properly supervised. Dr. Gonzalez also illustrates the biases within the scientific community that make fair testing of unconventional treatments so difficult.

The Introduction, the Table of Contents, and Reviews can be viewed on the New Spring Press site.

“This extraordinary story paints a detailed picture of mismanagement of a promising clinical trial of pancreatic cancer therapy by vested interests of the National Cancer Institute, the National Institutes of Health, and Academia. The story is one of conviction, persistence and dedication in the face of opposition by the cancer industry.” Kilmer McCully, M.D., author of The Heart Revolution


One Man Alone: An Investigation of Nutrition, Cancer, and William Donald Kelley

One Man Alone Cover

Nicholas J. Gonzalez, MD
ISBN: 978-0-9821965-1-9
Available through New Spring Press and through Amazon

In this monograph, Dr. Gonzalez describes his investigation of the nutritional/enzyme cancer treatment developed by the alternative practitioner Dr. William Donald Kelley. In addition to a discussion of Kelley's treatment approach, the book includes 50 case histories of successfully treated cancer patients. Although first completed in 1986, this monograph was not published until 2010, rewritten and with an updated introduction by Dr. Gonzalez. The book is now available to all those with an interest in cancer in general, the enzyme treatment of cancer in particular, alternative medicine, and Dr. Kelley.

The Introduction, the Table of Contents, and Reviews can be viewed on the New Spring Press site, along with a sample case report of a remarkable patient whose advanced prostate cancer regressed under Kelley's care.

“I especially enjoyed Dr. Gonzalez' presentation of Dr. Kelley's case history data. I think the argument relating to the rarity of spontaneous remission dramatizes the power of the results. The case histories themselves are very dramatic, leaving no doubt to anyone with a reasonable mind, of the efficacy of Dr. Kelley's program.” Stephen Levine, Ph.D. reviewing the book on Amazon.


The Trophoblast and the Origins of Cancer: One solution to the medical enigma of our times

Trophoblast cover

Nicholas J. Gonzalez, MD and Linda L. Isaacs, MD
ISBN: 978-0-9821965-0-2
Available through New Spring Press and through Amazon

In this book, Dr. Gonzalez and Dr. Isaacs provide a comprehensive review of Dr. John Beard's 100-year-old theories about cancer, from the perspective of contemporary molecular biology. The authors show how Dr. Beard most likely discovered stem cells, and very well may have uncovered the root origins of cancer - and its effective treatment with proteolytic enzymes. The book includes extensive case histories of cancer patients successfully treated with the Gonzalez nutritional-enzyme regimen.

The Table of Contents, an excerpt from the Introduction, and Reviews are available on the New Spring Press site. A longer section from the book was published in the journal The Original Internist as an article, The Evolution of Enzyme Treatment.

“Dr. Gonzalez and Dr. Isaacs have done an outstanding job presenting this material. It's a compelling biochemical drama with powerful insights and is wonderfully written. The stem cell connections are thrilling.” Stephen Levine, Ph.D. reviewing the book on Amazon.


The Enzyme Treatment of Cancer and Its Scientific Basis

Enzyme Treatment of Cancer cover

John Beard D.Sc.
Foreword by Nicholas J. Gonzalez MD
ISBN: 978-0-9821965-2-6
Available at New Spring Press and through Amazon

Dr. John Beard's study of the mammalian placenta led him to the conclusion that in its early incarnation, this tissue behaves much as a cancerous tumor. He then proposed that pancreatic enzymes regulate placental development, and in turn represent the body’s main defense against cancer. In 1911, he published The Enzyme Treatment of Cancer to favorable reviews. Though in his lifetime the scientific community never embraced his ideas about cancer – he died in relative obscurity in 1924 – in recent years, evidence from molecular biology and stem cell research increasingly confirms many of Dr. Beard’s fundamental precepts. This historic work is now available again, in a carefully recreated reproduction with a foreword by Dr. Gonzalez.

We plan to publish more books - further information will be posted closer to the publication dates. For updates, subscribe to our announcement list or see the website of New Spring Press.
