abstract: OBJECTIVE
  To investigate the survival of patients with inoperable non-small-cell lung cancer treated with combined radiochemotherapy. Frequency of local progression versus systemic dissemination after radiotherapy respectively radiochemotherapy. Extend of the toxicity of a combined modality treatment.
  
  
  METHODS
  60 inoperable patients (42 M0- and 18 M1-stage) with non-small-cell lung cancer who had received combined radiochemotherapy (RT+CT) were examined retrospectively. Different drugs or drug combinations were used. The sequence of radiotherapy and chemotherapy also differed. The survival was compared to that of another group of patients who had received at least 50 Gy with definitive radiotherapy at the same period of time (RT: N = 135). The Karnofsky performance index (KPI) was on an average of 80% in both groups. The primary of patients with systemic disease was treated by radiation when it became symptomatic or when it showed an evident progression.
  
  
  RESULTS
  The two investigated treatment groups were comparable regarding KPI, histology, stage, tumor dose and age. The survival was significantly better when chemotherapy was added to radiotherapy. The median survival times in months were as follows: M0: RT 10.6/RT+CT 14.7; M1: RT 6.0/ RT+CT 9.3. Local tumor control was the major problem with or without chemotherapy (local progression of about 70% in both groups). The toxicity of radiochemotherapy was acceptable (bone marrow toxicity WHO-grade 4: 10.5%: nausea WHO-grade 4: 3%).
  
  
  CONCLUSIONS
  In the absence of medical contraindications and with a KPI of at least 70% a combined radiochemotherapy in patients with inoperable non-small-cell lung cancer seems to be possible even if high radiation doses are used. Randomized studies are necessary to prove the impact on survival of an additional chemotherapy.
