Application of PET/CT images for simulation in Radiation therapy planning

SUMMARY

Background: Application of PET/CT images for simulation in Radiation therapy planning is one of the most advantage techniques in cancer treatment. In 2009, Nuclear Medicine and Oncology Center of Bach Mai Hospital was the fi rst place in Vietnam, where PET/CT simulation for radiation therapy planning has been conducted successfully for cancer patients.

Objective: To build the PET/CT simulation process in radiation treatment planning for esophageal cancer. Subjects and methods: 50 esophageal cancer patients treated by radiation.

Results: Simulation for radiotherapy in esophageal cancer: PET/CT has higher values than CT such as detecting lesions more precisely and more clearly. Patients in our study had good response and less complication: overall response (complete and partial) with improving clinical symptoms: 80%, size of tumor reduced in 83% patients. Common complication is depletion (in 34% patients). Most complications are mild and can be treated by medicine.

Conclusion: Nuclear Medicine and Oncology Center Bach Mai Hospital has standardized the PET/CT simulation process for esophageal cancer patients with initial good results.
