ABSTRACT

Objective To investigate the influence of interoperation radiation therapy (IROT) on immunity of patients with cervical cancer at Ⅱ b stage. Methods Before and after radiotherapy, T lymphocyte subsets of 61 cervical cancer patients at Ⅱ b stage including 28 patients with IROT and 31 with simple radiotherapy (SR) were tested by flow cytometry, with 20 normal people as the controls(NC). Results Before radiotherapy, radio CD 4, CD 4/CD 8 decreased obviously in cervical cancer patients. There was no obvious difference in immunity between IROT and SR group. After radiotherapy, radio CD 4, CD 4/CD 8 decreased obviously in 61 cervical cancer patients. But SR group was significantly lower than IROT group. Conclusion The influence of IROT on immunity of patients with cervical cancer at Ⅱ b stage was weaker than that of simple radiotherapy, and IROT contributed to the recovery of patients after radiotherapy.
