Nano-delivery of Gemcitabine Derivative as a Therapeutic Strategy in a Desmoplastic KRAS Mutant Pancreatic Cancer.
Article in The AAPS journal, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Pancreatic ductal adenocarcinoma remains one of the challenging malignancies to treat, and chemotherapy is the primary treatment strategy available to most patients. Gemcitabine, one of the oldest chemotherapeutic drugs approved for pancreatic cancer, has limited efficacy, due to low drug distribution to the tumor and chemoresistance following therapy. In this study, we delivered gemcitabine monophosphate using lipid calcium phosphate nanoparticles, to desmoplastic pancreatic tumors. Monophosphorylation is a critical, rate-limiting step following cellular uptake of gemcitabine and precursor of the pharmacologically active gemcitabine triphosphate. Our drug delivery strategy enabled us to achieve robust tumor regression with a low parenteral dose in a clinically relevant, KRAS mutant, syngeneic orthotopic allograft, lentivirus-transfected KPC cell line-derived model of pancreatic cancer. Treatment with gemcitabine monophosphate significantly increased apoptosis of cancer cells, enabled reduction in the proportion of immunosuppressive tumor-associated macrophages and myeloid-derived suppressor cells, and did not increase expression of cancer stem cell markers. Overall, we could trigger a strong antitumor response in a treatment refractory PDAC model, while bypassing critical hallmarks of gemcitabine chemoresistance.
