Prophylactic Antitumor Effect of Mixed Heat Shock Proteins/Peptides in Mouse Sarcoma.
Article in Chinese medical journal, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundTo develop a vaccine-based immunotherapy for sarcoma, we evaluated a mixture of heat shock proteins (mHSPs) as a vaccine for sarcoma treatment in a mouse model. Heat shock protein/peptides (HSP/Ps) are autoimmune factors that can induce both adaptive and innate immune responses; HSP/Ps isolated from tumors can induce antitumor immune activity when used as vaccines.
methodsIn this study, we evaluated the effects of mHSP/Ps on prophylactic antitumor immunity. We extracted mHSP/Ps, including HSP60, HSP70, GP96, and HSP110, from the mouse sarcoma cell lines S180 and MCA207 using chromatography. The immunity induced by mHSP/Ps was assessed using flow cytometry, ELISPOT, lactate dehydrogenase release, and enzyme-linked immunosorbent assay.
resultsOf S180 sarcoma-bearing mice immunized with mHSP/Ps isolated from S180 cells, 41.2% showed tumor regression and long-term survival, with a tumor growth inhibition rate of 82.3% at 30 days. Of MCA207 sarcoma-bearing mice immunized with mHSP/Ps isolated from MCA207 cells, 50% showed tumor regression and long-term survival with a tumor growth inhibition rate of 79.3%. All control mice died within 40 days. The proportions of natural killer cells, CD8+, and interferon-γ-secreting cells and tumor-specific cytotoxic T-lymphocyte activity were increased in the immunized group.
conclusionsVaccination with a polyvalent mHSP/P cancer vaccine can induce an immunological response and a marked antitumor response to autologous tumors. This mHSP/P vaccine exerted greater antitumor effects than did HSP70, HSP60, or tumor lysates alone.
