[Results of a comparative therapy study for inoperable lung cancer]

In a prospective randomized study 78 selected patients with bronchogenic cancer have been included, and five different treatment modalities have been compared (1. Biologic therapy; 2. Vitamin A + Cytoxan; 3. Vitamin A + Telecobalt irradiation; 4. Telecobalt irradiation; 5. Immunotherapy). No significant differences if survival times between the different groups have been observed. Nevertheless, significant differences of survival times were found between small cell and squamous cell carcinoma patients without respect to the therapy applied. The highest number of remissions was obtained by therapy 3, followed by 4 and 2. Consequences for further studies are discussed.
