After yielding culturing mouse TIL from U14 with Rosenberg's technique, the authors observed the antitumor effect of TIL combined with radiotherapy on established mouse transplanted tumor of uterocervical cancer U14. The results demonstrated TIL treatment or radiotherapy could inhibit the tumors growth. Combination showed a stronger inhibition and the E/O value was 1.1. It implied that an additive effect was gotten when combining TIL with radiotherapy.
