Brief Summary:
The aim of the study is to retrospectively monitor the 'gross tumor volume' (GTV) before initiation of radiotherapy and its changes during radiotherapy and to correlate them with retrospectively recorded patient data, as well as with prognostic and therapeutic outcome after definite radiotherapy of locally advanced NSCLC in stage UICC III.

Condition or disease
Non Small Cell Lung Cancer Stage III

Locally advanced NSCLC-patients
Inoperable stage III (A and B) non-small-cell lung cancer (NSCLC) with indication for radical radiotherapy.

Primary Outcome Measures :
  1. Overall Survival (months) [ Time Frame: 5 months ]
    from the start of Radiotherapy until death / last seen during follow up

Secondary Outcome Measures :
  1. Absolute Basal Gross Tumor Volume (ml) before Radiotherapy (GTV1) [ Time Frame: 5 months ]
    in ml (cc) as detected by initial planning CT or diagnostic CT before the start of RT

  2. Absolute Gross Tumor Volume before Radiation Boost (GTV2) [ Time Frame: 5 months ]
    in ml (cc) as detected in re-planning CT or CBCT before initiation of radiation boost

  3. Relative Gross Tumor Volume Changes (delta GTV related to basal GTV) [ Time Frame: 5 months ]
    percental increase / decrease of GTV in relation to basal GTV1
