[Problematic management of tumors with a very high proliferation coefficient: a case of an embryonal rhabdomyosarcoma of the right orbit in an eleven-year-old child].

We propose through the retrospective analysis of this document, to explain the inefficiency of the action of chemo and radiotherapy on tumours with a high proliferation coefficient but which are however known to be highly sensitive as well as curable with chemo and radiotherapy. This study shows the technical conditions and dispositions for a better therapeutic approach in these tumours with a rapid growth.
