Non-invasive Methods for Characterizing Adrenocortical Tumors

Summary
Researchers at the NCI developed a non-invasive method for distinguishing benign from malignant adrenocortical tumors using urine samples. The NCI seeks parties to co-develop a non-invasive, diagnostic method of distinguishing between benign and malignant adrenocortical tumors through the analysis of metabolites using urine samples.

Description of Technology

Adrenocortical neoplasms are commonly found in patients, yet malignant tumors resulting in adrenocortical cancer (ACC) are rare. An accurate diagnosis of ACC is important to a). determine the proper therapeutic strategy for patients, and b). mitigate the costs and risks of invasive surgeries. Improved pre-operative diagnostics would preclude unnecessary surgical intervention on benign adrenocortical neoplasms and lead to appropriate treatment options for malignant adrenocortical cancer (ACC).

Researchers at the NCI Endocrine Oncology Branch developed a non-invasive method to detect (ACC) in urine. They identified four metabolite markers in patient urine samples and have shown that these are sensitive and specific to malignant adrenocortical tumors: creatine riboside, L-tryptophan, N,N,N-trimethyl-L-lysine, and 3-methylhistidine. This method differentiates benign and malignant tumors, and helps clinicians decide the best treatment options.

Potential Commercial Applications
