Abstract

Objective: Fine needle aspiration (FNA), followed by core needle biopsy (CNB) when needed, was adopted as the standard care for liver lesions in our institution. This study explores the diagnostic efficacy of combined image-guided FNA and CNB in liver lesion diagnosis. Method: We retrospectively reviewed all liver FNA cases performed in our institution between January 2010 and September 2018. A total of 550 cases from 531 patients (173 females) with a median age of 59 years (range, 13–90) were identified. All FNA cases were initially assessed with rapid on-site evaluation, and cell blocks were prepared. A total of 459 FNA specimens with concurrent CNBs were included in the study. Both FNAs and CNBs in the paired sampling were read by a cytopathologist, with expert consultation as needed. Results: The concordance rate between FNA and CNB was 85.2%. Combined FNA/CNB showed higher sensitivity in detecting malignant tumours when compared to FNA or CNB alone (98%, vs 87% and 92%, p < 0.001), especially for detecting metastatic tumours, hepatocellular carcinoma, and haematopoietic neoplasms (98%, 97%, and 94%, respectively; all p < 0.001). Combined FNA/CNB showed a lower false negative rate in malignant tumours than FNA or CNB alone (2%, vs 13% and 8%, p < 0.001). There was no significant difference among FNA, CNB, and combined FNA/CNB in diagnosing benign liver lesions. Conclusions: Combined liver FNA/CNB has high diagnostic efficacy for malignancy and a lower false negative rate than either procedure alone, especially in metastatic tumours, hepatocellular carcinoma, and haematopoietic neoplasms.
