This thesis is about the different treatment techniques and fractionation patterns of a small-cell and non-small-cell lung cancer. The lungs are a matched organ, which can often be affected by a carcinoma. A common reason of development of a lung carcinoma is nicotine abuse. This type of cancer can be divided into two main groups. It can be divided into the small-cell and the non-small-cell lung cancer. The treatment of these lung carcinomas can be performed with radiation therapy. There are a few different techniques. Furthermore, if the radiation is done in the thoracic region, healthy tissue can be affected, which has to be treated with care. This scientific work was written to present the different treatment techniques and fractionation patterns of a small-cell and non-small-cell lung cancer. The results showed that the treatment of a non-small-cell lung cancer is mostly done with stereotactic body radiotherapy. In this type of treatment, high single doses are used. Small-cell lung cancer is often treated with three dimensional radiotherapy or with intensity modulated radiotherapy. However, the use of stereotactic body radiotherapy is increasing in regard to the small-cell lung cancer.
