Updated versions of the Neoplasm Classification are now available:
The Neoplasm Classification contains over 135,000 classified names of neoplasms in a biological hierarchy based on developmental lineage of the tumor. It is the largest and most comprehensive neoplasm nomenclature in existence. It is available as a simple XML file, an RDF ontology, or a plain flat-file.
These files were prepared by Jules J. Berman. The first version of this file was created November 15, 2003. The modifications were created on March 13, 2008.
The following applies to the distributed documents:

In the Neoplasm Classification, all classified names of neoplasms are coded with a "C" followed by a 7 digit number other than 0000000 or 0000001.
For example, "C9168000" = rectal signet ring adenocarcinoma
In addition to classified terms, there are four groups of unclassified terms that are provided special items that follow the list of classified terms in this file.
"S" followed by 7 digits
"ST" followed by 7 digits
This list of unclassified terms coded as "C0000000" consists of general cancer terms that do not specify any particular neoplasm; overly specific terms that provide so-called pre-coordinated annotations related to terms contained elsewere in the Classification; and valid terms that have not been added (yet) to the list of classified neoplasm terms.
Examples of non-specific cancer-related terms are:
Examples of overly specific terms are:
squamous carcinoma of the nasal vestibule
gastric non-hodgkin lymphoma of mucosa-associated lymphoid tissue
primary primitive neuroectodermal tumor of the kidney
The terms that are coded with "C0000001" are precancers and related conditions that have not yet been added to the list of classified terms.
The terms that are coded "S" followed by 7 digits are inherited syndromes that have a neoplastic component (i.e., the occasional or frequent appearance of neoplasms in the syndrome).
The terms that are coded "ST" followed by 7 digits are staging terms used by oncologists.
The classification is intended for informatics projects that use computer parsing techniques. Programmers should simply insert statements that filter the unclassified terms included in the file.

In June, 2014, my book, entitled Rare Diseases and Orphan Drugs: Keys to Understanding and Treating the Common Diseases was published by Elsevier. The book builds the argument that our best chance of curing the common diseases will come from studying and curing the rare diseases.
I urge you to read more about my book. There's a generous preview of the book at the Google Books site. If you like the book, please request your librarian to purchase a copy of this book for your library or reading room.
