Aspirin prolongs survival and reduces the number of Foxp3+ regulatory T cells in a genetically engineered mouse model of pancreatic cancer.
Article in Langenbeck's archives of surgery, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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 AND
aimsGemcitabine became the reference regimen for advanced pancreatic cancer after a randomized trial showed significant improvement in the median overall survival. Since then, the combination of gemcitabine with a variety of cytotoxic and targeted agents has generally shown no significant survival advantage as compared with gemcitabine alone. Only the addition of erlotinib to gemcitabine resulted in a significant but very small improvement in overall survival, coming along with a very uncomfortable rash in the patients. Therefore, new adjuvant agents with very low toxic levels are needed. In this study, we used a genetically engineered mouse model of pancreatic cancer to evaluate the chemotherapeutic potential of aspirin as an adjuvant agent to gemcitabine.
methodsDrug treatment was initiated at the age of 3 months. LsL-Kras (G12D) ; Pdx1-Cre or LsL-Kras (G12D) ; LsL-Trp53 (R172H) ; Pdx1-Cre transgenic mice were randomly assigned to receive either mock treatment, gemcitabine, or a combination of gemcitabine and aspirin. All mice were treated until death. The effect of aspirin was evaluated by histopathological analyses and immunostaining.
resultsGemcitabine prolonged overall median survival of LsL-Kras (G12D) ; LsL-Trp53 (R172H) ; Pdx1-Cre mice by 31 days as compared to mock-treated animals (median survival, 190 vs. 159 days; p = 0.396). Addition of aspirin to gemcitabine even extended the survival for ten more days, leading to a prolonged survival by 41 days, reaching virtually statistical significance versus the control group (median survival, 200 vs. 159 days; p = 0.05). Furthermore, we found that administration of aspirin in combination with gemcitabine reduced the number of Foxp3(+) regulatory T cells significantly.
conclusionIn conclusion, we identified aspirin as an effective adjuvant agent to gemcitabine in the treatment of PDAC. While fundamental differences in biology suggest the need for caution in equating mouse tumors with their human counterparts, mouse models nevertheless represent an important source of insight regarding human neoplasia. Further studies are necessary to confirm the hypothesis that aspirin might be an effective well-tolerated chemotherapeutic adjuvant agent for pancreatic cancer.
