Optimizing cancer cure dialog: an analysis of pancreatic cancer patients' views regarding survival and cure.

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
backgroundPancreatic ductal adenocarcinoma (PDA) is a highly lethal cancer. Clinicians commonly refer to surgical therapy as resection with curative intent. However, PDA cure rates after resection remain unknown and the definition of cure remains vague. We investigated how patients (the majority undergoing resection), family members, and clinicians understand the concept of cure, to better inform discussions with patients regarding PDA prognosis.
methodsIn a prospective survey, cohorts were asked to indicate the best definition of cure from three choices: 5-year survival endpoint (typically used in the literature), a biological endpoint without biochemical or radiographic signs of disease (similar to the NCI definition), or a practical endpoint where life span approximates similarly aged patients without PDA. Fleiss' kappa statistic was calculated to measure inter-rater agreement.
resultsPatients, family members, and health care professionals (N = 200) agreed that renormalization of life expectancy was the preferred definition of cure in the context of pancreatic cancer. Inter-rater agreement was highest for the patient and family member groups (Fleiss' kappa 0.27 and 0.40, respectively, P < 0.001), while variability was observed between health care professionals (Fleiss' kappa 0.11, P < 0.001).
conclusionsIn all groups surveyed, the probability for a normal life expectancy is the preferred long-term metric in patients with early-staged pancreatic cancer. Renormalization of life expectancy appears to be an important therapy goal for PDA patients and it is advisable to address this topic during clinical discussions.
