ABSTRACT
Objective:
To investigate the correlation between radiation dose of the pelvic bone marrow of different anatomical bony sites and the incidence of neutrophil toxicity during the three-dimensional radiotherapy concurrent chemotherapy for cervical cancer.Methods:
Clinical data of 117 cervical cancer patients who received three-dimensional radiotherapy concurrent chemotherapy from 2016 to 2018 were retrospectively analyzed. The dosimetric parameters included D mean, V 5Gy, V 10Gy, V 20Gy, V 30Gy, V 40Gy and V 50Gy. The correlation between the dosimetric parameters and the lowest neutrophil count was analyzed by linear regression analysis. Clinicopathological features and dosimetric parameters were included into the multivariate regression analysis model.Results:
The incidence rates of neutrophil toxicity (grade 1-4) were 10.3%, 27.4%, 11.1% and 10.3%, respectively. The linear regression analysis showed that the D mean and V 50Gy of lumbosacral vertebrae (LS), the D mean, V 5Gy, V 10Gy, V 20Gy, V 30Gy, V 40Gy and V 50Gy of the ilium were significantly correlated with the grade 2-4 neutrophil toxicity ( P=0.035、<0.001、<0.001、=0.001、=0.003、=0.001、<0.001、<0.001、<0.001). Multivariate analysis demonstrated that the V 20Gy, V 30Gy and V 50Gy of the LS, the D mean, V 5Gy, V 10Gy, V 20Gy and V 30Gy of the ilium were significantly correlated with the grade 2-4 neutrophil toxicity ( P=0.046、0.038、0.049、0.041、0.039、0.029、0.036、0.029).Conclusion:
During the process of three-dimensional radiotherapy concurrent chemotherapy for cervical cancer, the volume of medium-and high-dose of LS and the volume of low-and medium-dose of ilium are significantly correlated with the risk of neutrophil toxicity.
