Tumoral metabolism variation during radiotherapy (R.T.E.) evaluated by PET-F.D.G. among patients bearers of primitive bronchi tumors

The objective of this study is to describe the variation of the tumor metabolism during a radiotherapy for patients treated by exclusive radiotherapy or concomitant radio chemotherapy for a non at small cells pulmonary tumor. Conclusions: the PET-T.D.M. during an external radiotherapy is interpretable. As regard of the variability of the tumor metabolism during a radiotherapy, the predictive value on the upgradability of the tumor pathology of a PET-F.D.G. realised between 28 and 42 Gy would be worthy of being evaluated.
