[Inoperable non-small-cell bronchial carcinoma: macroscopic and microscopic tumor behavior during and after radiotherapy with curative intent].

The supervision of the efficacy of therapy with curative aim in inoperable NSCLC focus on clinical and radiological parameters and the survival rate. But the decision about the local tumour elimination lies in the microscopic area, which cannot be controlled neither by laboratory tests nor by radiological examinations. About twenty years ago with support of our pneumologist we carried out bronchoscopies and biopsies depending on the applied radiation dose.
