1 · What the graph read from it

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.

2 · The registry

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

purposePancreatic cancer is the fourth cause of death from cancer in the western world. Majority of patients present with advanced unresectable disease responding poorly to most chemotherapeutic agents. Chemotherapy for pancreatic cancer might be improved by adjusting it to individual genetic profiles. We attempt to identify genetic predictors of chemosensitivity to broad classes of anticancer drugs. EXPERIMENTAL

designUsing a panel of genetically defined human pancreatic cancer cell lines, we tested gemcitabine (antimetabolite), docetaxel (antimicrotubule), mitomycin C (MMC; alkylating), irinotecan (topoisomerase I inhibitor), cisplatin (crosslinking), KU0058948 (Parp1 inhibitor), triptolide (terpenoid drug), and artemisinin (control).

resultsAll pancreatic cancer cell lines were sensitive to triptolide and docetaxel. Most pancreatic cancer cells were also sensitive to gemcitabine and MMC. The vast majority of pancreatic cancer cell lines were insensitive to cisplatin, irinotecan, and a Parp1 inhibitor. However, individual cell lines were often sensitive to these compounds in unique ways. We found that DPC4/SMAD4 inactivation sensitized pancreatic cancer cells to cisplatin and irinotecan by 2- to 4-fold, but they were modestly less sensitive to gemcitabine. Pancreatic cancer cells were all sensitive to triptolide and 18% were sensitive to the Parp1 inhibitor. P16/CDKN2A-inactivated pancreatic cancer cells were 3- to 4-fold less sensitive to gemcitabine and MMC.

conclusionsChemosensitivity of pancreatic cancer cells correlated with some specific genetic profiles. These results support the hypothesis that genetic subsets of pancreatic cancer exist, and these genetic backgrounds may permit one to personalize the chemotherapy of pancreatic cancer in the future. Further work will need to confirm these responses and determine their magnitude in vivo.
