Prospective Evaluation of Associations between Cancer-Related Pain and Perineural Invasion in Patients with Resectable Pancreatic Adenocarcinoma.
Trial report in Journal of gastrointestinal surgery : official journal of the Society for Surgery of the Alimentary Tract, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
introductionPerineural invasion is a unique characteristic of pancreatic adenocarcinoma biology and is present in the majority of resected pathologic specimens. The purpose of this study was to understand the relationships between preoperative pain and perineural invasion in patients with pancreatic adenocarcinoma.
methodsFifty-two chemotherapy naive patients undergoing resection for pancreatic adenocarcinoma from 2012 to 2014 completed a previously validated Brief Pain Inventory survey for preoperative clinical pain scoring. Preoperative pain was correlated with multiple clinicopathologic features.
resultsPreoperative pain was not associated with pathologic cancer stage, lymph node status, lymph node positivity ratio, resection margin status, or tumor location within the pancreas. In the subgroup of pancreatic head cancers, pain interference with affect was associated with the absence of perineural invasion (p = 0.02). Patients with stage I cancer had higher pain interference scores than those with stage II cancer (p = 0.02).
conclusionsPreoperative pain does not predict the presence of perineural invasion or other pathologic prognostic factors in patients with resectable pancreatic adenocarcinoma. Higher pain scores in pancreatic head cancers correlated with absence of perineural invasion and early cancer stage. The effects of preoperative pain on quality and interference of daily life deserve further investigation in larger prospective studies involving patients with pancreatic cancer.
