Radiation therapy is directed against the primary tumor. Regional lymph nodes are also irradiated for regional metastases.
Depending on the localization of the primary tumor and/or T stage, regional lymph nodes may have to be irradiated due to high probability of microscopic disease.
Treatment is given alone or in combination with surgery (T4), possibly chemotherapy (T3-T4).
The target volume is adapted individually.
- Eliminate tumor
- Reduce tumor volume
- Remove or limit extent of regional metastases
