RE:RE:RE:RE:RE:RE:RE:About the addition of up to 9 CSS ...I think they're still shy of pdt for NMIBC because of the bad experience with photofrin. Photofrn was approved for NMIBC by Health Canada in 1996. It was abandoned because they got the dosimetry wrong and ended up damaging too much healthy tissue. An unacceptably high proportion of patients experienced underlying muscle damage which caused incontinence. This is why Theralase has made such a fetish of getting dosimetry right. And they have done it. (IMHO)
