Hi King Farouk,
You know my professor Eva Hellström-Lindberg, who is a very careful and well known expert in MDS, has found that Neupogen (GCSF) not increases the risk for leucemic transformation:

When the latest BMB and all cultures are have been taken your father could start with Neupogen. All guidelines for MDS treatment recommend that instead of waiting for next infection perhaps with virus or fungi that are difficult to treat.

Hope your father will get the very best treatment in the future too!
Kind regards
