Abstract: |
| |
The best option for treatment of anal cancer is chemoirradiation. FDG-PET detects the primary tumor and metastatic
involved lymph nodes better and more frequently than CT only. During last decade, fusion of different imaging modalities
became important factor in radiotherapy treatment planning. Patient was diagnosed for squamous cell carcinoma
by colonoscopy and FDG/PET followed by histopathological confirmation. A precise determination of target volume is
very important in radiotherapy. In recent years higher utilization of FDG-PET CT fusion in radiotherapy treatment planning
of anal cancer is recorded. Image registration and fusion between CT for radiotherapy treatment planning and
FDG PET can help better visualization and especially in the determination of boost target volume. We observed much
better detection of affected lymphatics by the data obtained by image co-registration of PET and CT data. This fact
allowed us to increase dose prescribed to tumor and affected lymph nodes. PET is very important imaging modality
for patients with anal canal cancer. FDG-PET has proved to be important tool for the radiotherapy treatment planning
of anal canal carcinoma. |
