1 · What the graph read from it

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.

2 · The registry

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

Clinical-grade doxorubicin encapsulated low temperature sensitive liposomes (LTSLs) were combined with a clinical magnetic resonance-guided high intensity focused ultrasound (MR-HIFU) platform to investigate in vivo image-guided drug delivery. Plasma pharmacokinetics were determined in 3 rabbits. Fifteen rabbits with Vx2 tumors within superficial thigh muscle were randomly assigned into three treatment groups: 1) free doxorubicin, 2) LTSL and 3) LTSL + MR-HIFU. For the LTSL + MR-HIFU group, mild hyperthermia (40-41 °C) was applied to the tumors using an MR-HIFU system. Image-guided non-invasive hyperthermia was applied for a total of 30 min, completed within 1h after LTSL infusion. High-pressure liquid chromatography (HPLC) analysis of the harvested tumor and organ/tissue homogenates was performed to determine doxorubicin concentration. Fluorescence microscopy was performed to determine doxorubicin spatial distribution in the tumors. Sonication of Vx2 tumors resulted in accurate (mean = 40.5 ± 0.1 °C) and spatially homogenous (SD = 1.0 °C) temperature control in the target region. LTSL + MR-HIFU resulted in significantly higher tumor doxorubicin concentrations (7.6- and 3.4-fold greater compared to free doxorubicin and LTSL respectively, p<0.05, Newman-Keuls). This improved tumor concentration was achieved despite heating <25% of the tumor volume. Free doxorubicin and LTSL treatments appeared to deliver more drug in the tumor periphery as compared to the tumor core. In contrast, LTSL + MR-HIFU treatment suggested an improved distribution with doxorubicin found in both the tumor periphery and core. Doxorubicin bio-distribution in non-tumor organs/tissues was fairly similar between treatment groups. This technique has potential for clinical translation as an image-guided method to deliver drug to a solid tumor.
