Abstract:
Laboratory testing focused on the genetic basis of disease has become an increasingly important part of the analysis of tissue specimens traditionally evaluated only by histopathologic examination. Molecular laboratory testing in surgical pathology is usually only discussed in the context of its role in diagnosis, but genetic techniques have attained an increasingly prominent role in testing to predict prognosis, to identify likelihood of response to various treatment options, to monitor for minimal residual disease, and to identify disease predispositions.

Combination Therapies and Personalized Medicine
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
