Are Perceived Stress and Cytokine Genotypes Clinically Feasible as Predictors of Psychoneuroimmune Symptoms in Advanced Cancer?
Article in The Permanente journal, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
contextGenetic variability and perceived stress have been identified as likely predictors of psychoneuroimmune (PNI) symptoms in patients with cancer. In the clinical setting, the ability to identify the patients at greatest risk of development of severe PNI symptoms continues to be elusive.
objectiveTo evaluate the feasibility of cytokine genes and perceived stress scores as clinical predictors of PNI symptom severity in patients with a new diagnosis of advanced cancer compared with cancer-free controls (CFCs).
designPatients with advanced-stage cancer beginning chemotherapy and CFCs completed questionnaires at 6 time points during 24 weeks and provided blood samples for genotyping.
main outcome measuresAssociations between single-nucleotide polymorphisms in cytokine genotypes and perceived stress scores with PNI symptom severity were evaluated using bivariate analysis.
resultsForty-two participants were recruited (21 patients with cancer and 21 CFCs). Patients with cancer and CFCs were demographically similar and had similar allele frequencies for 15 of 16 single-nucleotide polymorphisms. Cancer-affected patients reported higher perceived stress and PNI symptom severity. Associations were found between several single-nucleotide polymorphisms and PNI symptoms, but no clear pattern emerged across time. Perceived stress was associated with PNI symptom severity for memory problems and fatigue at all 6 time points.
conclusionPerceived stress performed better than cytokine genotypes as a clinical predictor of PNI symptoms in this small-scale study. Assessing perceived stress is an easy and low-cost approach that can be used to identify patients at high risk of PNI symptom development.
