Abstract:
Objective:To explore the application value of CT-guided percutaneous coaxial needle biopsy (CT-PTCB) in the diagnosis of malignant tumors.Methods:A retrospective case series study was conducted. The clinical data of 802 suspected malignant tumor patients who underwent CT-PTCB upon admission to Beijing Chaoyang District Huanxing Cancer Hospital from January 2019 to December 2023 were analyzed. All patients underwent imaging follow-up combined with CT-PTCB or surgical pathology to determine the final diagnosis. The CT-PTCB puncture effect, diagnosis effect and incidence of complications were recorded.Results:Among the 802 patients, 488 (60.8%) were male and 314 (39.2%) were female, with the age of (51±11) years. The puncture sites included 610 cases (76.1%) in the chest, 169 cases (21.1%) in the abdomen, 17 cases (2.1%) in the bones, and 6 cases (0.7%) in the pelvic cavity. The success rate of CT-PTCB puncture upon admission was 99.5% (798/802), the diagnostic accuracy was 96.5% (774/802), and the false negative rate was 3.5% (28/802). The incidence of pneumothorax and bleeding in patients undergoing pulmonary CT-PTCB was 13.0% (75/575) and 17.9% (103/575), respectively; the incidence of puncture bleeding in patients undergoing liver CT-PTCB was 0.8% (1/125), and the incidence of pain was 1.6% (2/125); the incidence of pneumothorax in patients undergoing mediastinal CT-PTCB was 8.7% (2/23); no obvious complications were observed in other puncture sites. All complications were cured through active treatment.Conclusions:The application of CT-PTCB for the diagnosis of malignant tumors has high success rate and diagnosis rate, and is safe and minimally invasive.
