Dueñas-González A`［4］ study demonstrated that the 3 year progress free survival and distant metastasis free survival has increased by 8.9% and 8.3% by the radial radiotherapy combined with concurrent chemotherapy with weekly gemcitabine and cisplatin and adjuvant chemotherapy with triweekly gemcitabine and cisplatin. Ryu SY［5］ also reported the triweekly concurrent cisplatin with 3 cycles improved survival outcomes compared with weekly concurrent cisplatin. Retrospective studies by Tang and Jelavić-TB［6-7］ suggested that the adjubant chemotherapy after CCRT has better DMFS and OS.
