Radiation therapy is targeted towards 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 are irradiated due to high probability of microscopic disease.
This therapy is foremost given to patients with inoperable tumors, or preoperatively to render tumor more accessible for surgery.
The target volume is adapted individually.
- Eliminate tumor
- Reduce tumor volume
- Remove or limit extent of regional metastases
