Along with the development of molecular bioengineering technology, photosensitizer improvement, and the progress of PDT instrument development, we believe that the therapeutic effects of PDT in lung cancer treatment may be further improved in the near future.
Since all instruments are identical we believe a priori that they all have identical probabilities of failure, typically from space radiation.
