[Pancreatic cancer. The relative importance of neoadjuvant therapy]

Neoadjuvant radiochemotherapy in patients suffering from pancreatic cancer is presently not well established. Neoadjuvant radiochemotherapy is recommended to be applied in 5-8 weeks. The full dose of radiotherapy is between 50 and 54 Gy with 5FU used as radiosensitator. In patients with resectable pancreatic cancer, particularly in UICC-stage II neoadjuvant radiochemotherapy, this results in an improvement in survival: the median survival is between 15 and 30 months. In about 15% of the patients with resectable pancreatic cancer (UICC I-III), neoadjuvant radiochemotherapy results in downstaging. In combination with a R0-resection,neoadjuvant radiochemotherapy effects a reduction of local recurrence. Results from controlled clinical trials are necessary to objectify the benefits of neoadjuvant radiochemotherapy.
