Summary:
A new study has identified sonographic biomarkers that can predict eventual malignant transformation of pathologically confirmed cirrhotic nodules for patients at risk for hepatocellular carcinoma (HCC). These additional imaging features may have the potential to be adopted as ancillary or even major features to stratify probability for HCC in the contrast-enhanced LI-RADS system.

FULL STORY

An article published ahead-of-print in the January 2020 issue of the American Journal of Roentgenology (AJR) has identified sonographic biomarkers that can predict eventual malignant transformation of pathologically confirmed cirrhotic nodules for patients at risk for hepatocellular carcinoma (HCC).

Lead investigator Manxia Lin of China's Sun Yat-Sen University retrospectively studied 39 consecutive patients with 44 pathologically confirmed cirrhotic nodules who initially underwent contrast-enhanced ultrasound (CEUS) examination at detection, followed by conventional ultrasound every 3-4 months thereafter.

Fourteen nodules (31.8%) evidenced eventual malignant transformation after a median follow-up time of 26.7 months.

According to Lin and colleagues' results, the contrast arrival time difference between the cirrhotic nodule and the liver on CEUS proved useful in stratifying eventual malignant transformation risk -- "which may enable a more customized surveillance strategy," they noted.

"During surveillance," Lin et al. continued, "a relative growth rate of 30% or greater in 6 months or an absolute growth rate of 5 mm or greater in 6 months highly indicated malignant transformation."

Moreover, Lin's team determined that the absence of both echogenicity change and threshold growth "significantly excluded malignant transformation."

Acknowledging that additional studies will be necessary for validating possible biomarkers, Lin concluded: "These additional imaging features may have the potential to be adopted as ancillary or even major features to stratify probability for HCC in the CEUS LI-RADS system."
