In vivo optical pathology of paclitaxel efficacy on the peritoneal metastatic xenograft model of gastric cancer using two-photon laser scanning microscopy.

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
backgroundWe previously visualized in vivo responses to chemotherapy in a colorectal liver metastatic xenograft model using in vivo real-time and time-series intravital two-photon laser scanning microscopy (TPLSM). In this study, we established the method for evaluating the response of peritoneal xenografts to chemotherapy of metastatic gastric cancer using intravital TPLSM.
methodsRed fluorescent protein-expressing gastric cancer cells (NUGC4) were inoculated into the peritoneal cavity of green fluorescent protein nude mice.
resultsLaparotomy revealed that 2 weeks after inoculation, macroscopic peritoneal metastatic nodules were formed. The first intravital TPLSM session revealed that they were composed of red tumor cell clusters and green surrounding stroma. Paclitaxel was administered intraperitoneally after the first TPLSM three times a week for 7 days in the treatment group. At the second laparotomy, there were significantly fewer and smaller nodules in the treated mice than in the controls. The second intravital TPLSM session showed tumor cell fragmentation, swelling, and nuclear condensation in the metastatic nodules--a response to chemotherapy. There were multinuclear tumor cells in the paclitaxel-treated living mice.
conclusionsOur method may become a powerful tool for evaluating the efficacy of novel anti-gastric cancer drugs in a preclinical murine model with minimum interindividual variation.
