Re: Re: Return from China __ PDT

[Guest guest]

In China the common photosensitizer that is used is photofrin. This

is approved for use in the US. The flesh penetration of narrow bands

of light is very shallow so it will rarely be a first-line therapy

for advanced cancer. I do think that PDT is underutilized. I spent

many hours discussing PDT with the CEO of a company in China that

makes the equipment. I think that we would see better results if a

number of targeting porphyrin/chlorophyll/heme analogs were used

along with a variety of lasers. I may make some of these compounds

but right now there are not enough hours in the day.
