Dual-Mode Treatment of Hepatocellular Carcinoma Using RGD Cyclopeptide-Modified Liposomes Loaded with Ce6/DOX.
Article in International journal of nanomedicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Liver cancer is one of the most prevalent cancers globally, with approximately 90% of primary liver cancers being hepatocellular carcinomas (HCC). However, current systemic treatment options (whether monotherapy or combination therapy) are limited and offer only modest survival benefits. The effectiveness of a drug is largely determined by its concentration at the target site. Therefore, an effective drug delivery system must enhance drug accumulation at the target site, enable selective drug release there, and facilitate escape from lysosomes. Methods: cRGD-Lipo@Ce6/DOX was prepared by modifying c(RGDyK) onto the surface of drug-loaded liposomes containing Chlorin e6 (Ce6) and doxorubicin (DOX) through an amide reaction. The targeting capability and uptake mechanism of cRGD-Lipo@Ce6/DOX for HCC were analyzed using flow cytometry. To investigate drug release mechanisms and changes in subcellular distribution following ultrasound stimulation, further studies were conducted. The therapeutic efficacy and biosafety of this dual-modality therapy were then evaluated in an HCC subcutaneous tumor-bearing mouse model. Results: The prepared nanocomplex exhibits a surface charge of -9.91 ± 2.94 mV and an apparent size of 118.07 ± 1.46 nm. Modification of the RGD cyclic peptide on the surface of the drug-carrying liposomes enhanced the targeting and penetration efficiency for HCC. In vitro experiments on drug uptake mechanisms and release demonstrated that reactive oxygen species (ROS) generated by sonodynamic therapy (SDT) promote effective drug release from the carrier into the non-lysosomal region. The combined SDT and chemotherapy treatment achieved a 94% tumor inhibition rate and showed excellent biosafety in HCC subcutaneous tumor-bearing mice. Conclusion: Therefore, the effectiveness of the combination treatment strategy utilizing SDT in conjunction with chemotherapy provides additional treatment options for patients with HCC.
