Effect of the botanical formula LCS101 on the anti-cancer effects of radiation therapy.
Article in Journal of cancer research and clinical oncology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 and purposeThe botanical formula LCS101 has been shown in clinical research to reduce chemotherapy-induced toxicities. In pre-clinical research, the formula demonstrated selective anti-cancer effects, in part as a result of radical oxygen species (ROS) activity of the botanical components. The present study examined the interaction between LCS101 and radiation therapy on cancer cell lines.
methodsIncremental doses of LCS101 were added to breast adenocarcinoma (MCF7), prostate (DU145), transitional cell bladder carcinoma (T24), pancreatic epithelioid carcinoma (PANC-1), and osteosarcoma (U20S) cell lines 4 h after single-dose irradiation (range 0.5-4 Gy). Cell viability was tested using sulforhodamine B (SRB) assay after 1 week, with ROS activity examined using 1 mM of the ROS scavenger sodium pyruvate (ROS scavenger), testing cell viability with an SRB assay.
resultsThe addition of LCS101 to MCF7 (breast) and DU-145 (prostate) cancer cell lines resulted in a dose-dependent increase in the antiproliferative effects of radiation treatment. The addition of pyruvate inhibited radiation-induced cell death in all of the cell lines treated with LCS101.
conclusionsThe addition of the botanical formula LCS101 to irradiated cancer cells results in an apparent additive effect, most likely through a ROS-mediated mechanism. These findings support the use of LCS101 by patients undergoing radiation therapy, for both its clinical as well as anti-cancer effects.
