Background: In Western countries, only a small proportion of patients with hepatocellular carcinoma (HCC) can be treated with surgical resection. For other patients, locoregional management by transcatheter oily chemoembolization seems to be useful and warrants evaluation.
Methods: One hundred and twenty-seven French patients with an inoperable HCC were treated by transcatheter oily chemoembolization. The efficiency of the treatment was assessed by a comparison of this group with a group of 127 untreated patients. Each patient of the treated group was matched closely with an untreated patient for all the main clinical, anatomic, and biologic features that characterize the spontaneous evolution of HCC.
Results: The overall probabilities of survival in the treated group were 64%, 38%, 27%, and 27% at 1, 2, 3, and 4 years, respectively; those for the untreated group were 18%, 6%, and 5% at 1, 2 and 3 years, respectively (P < 0.0001). The survival was significantly increased in patients with Okuda Stage I and II disease (P < 0.0001), but not in those with Stage III. Karnofsky and Child-Pugh scores remained stable during the follow-up period and dropped only shortly before patients died.
Conclusion: Transcatheter oily chemoembolization is an efficient treatment for unresectable HCC for the palliation of symptoms as well as for the prolongation of survival with a good quality of life.

An experimental study on the diagnostic advantage of dual-energy computed tomography over single-energy scan to evaluate the treatment effect following transcatheter arterial chemoembolization.

Objectives: We assessed the diagnostic advantage of dual-energy computed tomography (DECT) over single-energy computed tomography (SECT) to evaluate lipiodol accumulation in target lesions following transcatheter arterial chemoembolization (TACE).
Methods: TACE was performed in 10 rabbits in whom the VX2 tumor was implanted in their left liver lobes. The miriplatin-lipiodol mixture was injected into the common hepatic artery.

Purpose: To determine how low inorganic phosphate stress (LIPS) induced by sevelamer particle transarterial embolization (S-TAE) affects immune regulation and angiogenesis in hepatocellular carcinoma.
Material And Methods: Transcatheter arterial embolization (TAE) using conventional ethiodized oil plus polyvinyl alcohol microspheres and S-TAE, which depletes intratumoral inorganic phosphate, were conducted on a McA-RH7777 orthotopic liver tumor model in rats, followed by the assessment of alterations in immunity-related and angiogenesis-related factors. The cells were cultured under hypoxic conditions and stimulated with LIPS to analyze the modulation of programmed cell death 1 ligand (PD-L1), vascular endothelial growth factor (VEGF)-α, and transforming growth factor-β1 expression using western blotting, quantitative real-time polymerase chain reaction, and immunofluorescence assays.
Creation of a Prediction Model of Local Tumor Recurrence After a Successful Conventional Transcatheter Arterial Chemoembolization Using Cone-Beam Computed Tomography Based-Radiomics.

Purpose: To create and evaluate prediction models of local tumor recurrence after successful conventional transcatheter arterial chemoembolization (c-TACE) via radiomics analysis of lipiodol deposition using cone-beam computed tomography (CBCT) images obtained at the completion of TACE.
Materials And Methods: A total of 103 hepatocellular carcinoma nodules in 71 patients, who achieved a complete response (CR) based on the modified Response Evaluation Criteria in Solid Tumors 1 month after TACE, were categorized into two groups: prolonged CR and recurrence groups. Three types of areas were segmented on CBCT: whole segment (WS), tumor segment (TS), and peritumor segment (PS).
Fusible and Radiopaque Microspheres for Embolization.

Article Synopsis
- Researchers developed new fusible microspheres for transcatheter arterial embolization (TAE) by using a multi-block copolymer that combines polyethylene glycol (PEG) and poly(ε-caprolactone) (PCL) to create elastic microspheres.
- These microspheres are loaded with a clinical contrast agent called lipiodol, which helps lower their melting temperature, allowing them to fuse together effectively during the embolization process.
- Testing on rabbit models showed that these microspheres caused significant ischemic necrosis and maintained radiopacity for a longer duration compared to existing commercial contrast agents, indicating their potential as a new embolic agent.

Article Synopsis
- The study evaluated the effectiveness and safety of a nonselective transarterial chemoembolization (TACE) method using cisplatin powder for treating multifocal hepatocellular carcinoma (HCC) after initial promising results from the Japanese Interventional oncology group.
- A review of medical records from TACE-naïve patients showed that out of 60 patients, the overall survival duration was 30.3 months, with a 65% overall response rate and 86.7% disease control rate.
- The results indicated that the DDP-H TACE treatment effectively reduced tumors while maintaining liver function, with minimal cases of lasting liver impairment.
