This invention describes the use of a laser scanning device for example a , laser scanning CYTOMETRY (LSC) with a double-fluorescent labeling technique as a quantitative method that can be used to objectively and accurately measure endothelial cell death, endothelial tumor cell death and blood vessel density of tumor tissue. These parameters can be used as markers of efficacy in tumors treated with anti-angiogenic or traditional therapies and can distinguish patients who respond to these drugs from those who do not.

Why it's free to use
- Filed November 6, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 6, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 6, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
