Objectives   To assess the feasibility of 3-dimensional conformal radiotherapy (3D-CRT) for recurrence cervix cancer.    Methods   Totally 42 patients with recurrence cervix cancer who were admitted in our institute from April 2004 to December 2007 and treated with 3D-CRT and conventional external radiation therapy were retrospectively studied. These 42 patients treated with 3D-CRT was group A. The other 34 matched patients treated with anterior posterior field radiotherapy at the same time period was group B. Pr

eliminary outcome and toxicity were evaluated in the 2 group.    Results   All patients completed the prescribed dose. Group A was (45.00±7.31) Gy and group B was (37.00±4.53) Gy. There was no significant difference in the 2 groups (

P

>0.05).The effective rate of group  A was 52.38% (22/42)

and group B was 32.35% (11/34). There was significant differences between the 2 groups (

P

<

0.05).The survival curve showed that the average survival time of group A was 18.13 months

and that of group B was 12.53 months. There was significant difference between the 2 groups (

P

<

0.01). In group A

acute grade ≥3 myelotoxicity were seen in 12 patients. One patient had vesicovaginal fistula.Two patients had rectovaginal fistula.In group B

acute grade ≥ myelotoxicity were seen in 8 patients. Two patients had vesicovaginal fistula.    Conclusion   The curative effect of 3D-CRT is better than anterior posterior field radiotherapy. The acute toxicity of 3D-CRT is acceptable.
