Abstract:
Objective To evaluate the efficacy and safety of ultrasound elastography in the diagnosis of pros-tate cancer.Methods 83 patients with prostate cancer were selected and diagnosed by transrectal ultrasound elastog-raphy (TRTE)and transrectal ultrasound(TRUS).The surgical pathology of the patients was used as diagnosis basis, and the efficacy of the two methods was evaluated.Results There were 102 nodules of all the 83 patients,44 patients'surgical pathology were benign,a total of 49 nodules,39 cases were vicious,a total of 53 nodules.47 nodules were gland nodules,accounting for 46.08% and 55 nodules were outer gland nodules,accounting for 53.92% of all the 102 nodules.There were 54 focis,the TRTE detected 36 focis,the detection rate was 66.67%,and TRUS detected 24 focis,the detection rate was 44.44%.The sensitivity,specificity and accuracy rates of TRTE were 66.67%, 68.65% and 67.64%,which were higher than 44.44%,64.58% and 53.92% of TRUS,and the differences were statistically significant (χ2 =10.710,P <0.05;χ2 =3.879,P <0.05;χ2 =4.084,P <0.05).The differences of pathological findings and TRTE,TRUS findings of the benign and malignant prostate nodules were not statistically significant (P >0.05 ).Conclusion It has higher diagnostic sensitivity,specificity and diagnostic accuracy for ultrasound elastography in the diagnosis of prostate cancer,which can improve the clinical diagnostic performance and worthy of clinical application.
