Sentinel Node Mapping Using Blue Dye

[Lani]

to stir up a hornet's nest with this imagine having all your patients calling in to see what dye was used and if their specimen could be reevaluated regarding ER status.

I hope this causes pathologists and surgeons to look into whether the concentration of methylene blue used by most surgeons could cause the misinterpretation of ER status.
Also, the article states that there are two other dyes used (more expensive, I think) that did not cause the problem.
There are other ways to test ER status as well.

So, I guess in the long term they need to investigate whether it is better to change how they test ER status or what dye they use (or its concetration) if they want to ensure the best results to determine the best treatment for each patient.

Glad this was of use!
