The value of ultrasound-guided biopsy in the diagnosis of benign and malignant solid tumors / 中国医师杂志

ABSTRACT

Objective To explore the value of ultrasound-guided coarse needle biopsy (US-CNB)in the diagnosis of benign and malignant solid tumors.Methods The clinical data of 317 patients with solid liver lesion detected by US-CNB were reviewed retrospectively.93 cases were diagnosed by pathology after operation,and 196 cases were diagnosed by biopsy,imaging and follow-up.The material satisfaction rate,diagnosis of benign and malignant tumors and postoperative complications were discussed in this study.Results Of the 317 cases,289 cases were successfully taken,28 cases were failed,and the success rate was 91.2％.The overall sensitivity of US-CNB to tumor and non tumor were 98.7％ and 95％ respectively,with the specificity of 95％ and 98.7％ respectively.The positive predictive values were 98.7％ and 95％respectively,and the negative predictive values were 95％ and 98.7％,respectively.No serious complications occurred after puncture.Conclusions Ultrasound-guided coarse needle biopsy is a safe,accurate and effective method to diagnose solid tumors.
