Supporting discoveries since 1987


Researchers have long considered the NCI supported Cooperative Human Tissue Network (CHTN) as a source for quality collection and preservation of tissue samples from remnant surgical tissue specimens. In an organized tissue procurement setting serving a large population of researchers, the trained procurement personnel, specialized reagents and monitoried frozen storage facilities assure the availability of quality research, monitored preservation techniques and temperature controlled shipping required for successful research support.

The CHTN Midwestern Division (MWD) has experienced an increase in investigator demand for fresh tissues over the past two years. Approximately 23% of the tissues distributed by the CHTN MWD is fresh tissue. Requests for frozen and formlin-fixed paraffin embedded tissues, however, remain constant and stable. The increased interest in fresh tissue likely reflects an increased focus on the study of vital cells in controlled environments for... Read more

The CHTN takes note that human tissue samples continue to play a major role in cancer research. One of the latest national cancer research efforts takes the form of the so called “Cancer Moonshot” program that has been organized by the office of Vice-President Joe Biden. While the CHTN itself has not been tapped for this effort, some of the CHTN Principal Investigators have been involved in information-gathering and organizational efforts for this program. One subprogram of the Cancer Moonshot has been thematically termed the Applied Proteogenomics Organizational Learning and Outcomes (APOLLO) consortium. APOLLO will build on the enormously successful The Cancer Genome Atlas (TCGA) and Clinical Proteomic Tumor Analysis Consortium (CPTAC). These previous programs have provided open access to raw genomic and proteomic data to cancer researchers that have been useful in both discovery research by data mining and validation of laboratory molecular findings in a larger dataset. Some... Read more

In 2012, a group of distinguished scientists convened at the National Cancer Institute (NCI) to discuss the problem of over diagnosis and hence overtreatment of cancer. This group published in 2014, the article entitled "Addressing over diagnosis and overtreatment in cancer" (Read the abstract Pub Med Reference (PMC4322920)). The group pointed out appropriately that cancer describes a wide range of diseases from indolent to fast growing lesions. They proposed a new terminology for indolent and precancerous disorders such as "indolent lesion of epithelial origin or IDLE”.

Among lesions they suggested would be overtreated low grade and intraductal breast lesions, low grade prostatic neoplasms and encapsulated thyroid neoplasms. The removal of the word "cancer" or "carcinoma" from the diagnosis of such lesions, which by their very nature haven't indolent clinical behavior and if left untreated... Read more
