| Abstract:: |
| Objective To evaluate the early side effects and influencing factors in patients undergoing intensity-modulated radiation therapy after cervical cancer surgery. Methods A retrospective analysis of 106 patients with cervical cancer who underwent postoperative intensity-modulated radiation therapy in our hospital from January 2014 to December 2017 was conducted. The occurrence of toxic and side effects were summarized, and the related clinical indicators were analyzed using univariate and multivariate analyses. Results The 3-year overall survival rate was 88.1%, and the 3-year progression-free survival rate was 84.8%. The incidence of acute hematologic toxicity greater than grade 3 was 33%. The incidence of early intestinal reactions was 35%, of which only 1.8% was greater than grade 3. Univariate analysis demonstrated that severe acute hematologic side effects were statistically significant (χ2=1.789-17.895,P<0.05) with the level of hemoglobin before radiotherapy, radiation in the abdominal aortic lymphatic drainage area or not, an increase of local radiotherapy dose in the target area, and chemotherapy or not. Multivariate analysis showed that concurrent chemotherapy significantly increased the incidence of severe acute hematologic toxicity (χ2=3.929,P<0.05). Conclusions In patients with cervical cancer undergoing postoperative intensity-modulated radiation therapy, grade 3 and greater toxic side effects are mainly related to hematological toxicity, and the incidence of severe bowel toxicity in the early stage is low. |
