Tumor-infiltrating neutrophil is an independent prognostic factor in pancreatic ductal adenocarcinoma.

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 (PDAC) remains one of the most lethal malignancies. Tumor-infiltrating neutrophils (TINs) have been implicated in tumor progression and poor prognosis; however, their roles in PDAC remain unclear. TINs have been shown to granulocytic myeloid-derived suppressor cells (G-MDSCs) which inhibit adaptive immune responses and share morphological and functional features with classical neutrophils. G-MDSCs, unlike classical neutrophils, express myeloperoxidase (MPO). We evaluated the significance of TINs and MPO expression as a marker for prognosis in the PDAC.
methodsWe retrospectively analyzed 128 patients with surgically resected PDAC. The presence of TIN was assessed on hematoxylin and eosin-stained slides and immunohistochemistry was performed for MPO.
resultsTINs were identified in 61.7% of patients with PDAC. Their presence was significantly associated with worse overall survival and recurrence-free survival. After adjusting for clinicopathological variables, TIN remained an independent predictor of a poor prognosis. MPO was expressed in all TIN within PDAC, but was absent in neutrophils within benign inflammatory conditions.
conclusionsTIN in PDAC represents an independent adverse prognostic factor and is likely to be G-MDSCs based on MPO expression. Assessing TIN and MPO status in preoperative biopsy specimens may offer valuable prognostic information and guide future therapeutic strategies for PDAC.
