Abstract
BACKGROUND

Transarterial chemoembolization (TACE) is a widely accepted palliative therapy modality for unresectable hepatocellular carcinoma (HCC). Although it is rarely curative, complete radiological response can be achieved in selected patients, leading to prolonged survival. Post-treatment tumoral calcification is an uncommon imaging finding in HCC and is rarely reported after drug-eluting beads TACE (DEB-TACE).

CASE SUMMARY

Two patients with large, solitary HCCs (> 5 cm) were treated with DEB-TACE, and both achieved complete radiological response after two treatment sessions. Approximately 1 year after DEB-TACE, imaging demonstrated progressive peripheral tumoral calcification. Over 6 years of follow-up, both patients remained in remission with preserved liver function.

CONCLUSION

These two cases highlight the potential for complete remission and long-term survival in selected patients with large HCC following DEB-TACE. The appearance of peripheral calcification may represent a late imaging marker of effective tumor necrosis and durable treatment response although prospective studies are warranted to clarify its prognostic value.

Core Tip: Tumoral calcification following transarterial chemoembolization (TACE) for hepatocellular carcinoma is a rare imaging finding, and its clinical significance remains unclear. This case report describes 2 patients with large hepatocellular carcinoma who developed complete radiological response after drug-eluting beads TACE, followed by progressive peripheral calcification and sustained disease-free survival for 6 years. The notable association between post-TACE calcification and long-term remission raises the possibility that calcification may serve as a late imaging biomarker of effective tumor necrosis and durable treatment response.
