So the last two cases did not survive, although there was definite improvement in one of the two last cases. We checked the names of the patients on the films, and the films were obtained at different institutions from the entire country, basically where the patients were located. And we had no reason to believe that these were not the results of the treatments. And I see a large volume of them. And the available treatments only rarely produce results like that.
Chemotherapy has very little to offer unless there is an experimental protocol somewhere.
Radiation, there are some reports indicating that radiation treatment in children particularly could lead to resolution of the tumors, although I don't know whether it is a permanent one or temporary. So when this happens it is very rare, and I have seen only isolated reports here and there where that has happened with radiation. Well, radiation should give these results, if it works at all, the first 2 months after completion of the treatment. In these cases, all the patients had already failed radiation because they were treated months, several months after radiation was given and had failed. If the tumor is low-grade astrocytoma, and we are talking about primary gliomas, if it is low grade, survival for years is possible.
