Expression Status of Serine Protease 27: A Prognostic Marker for Esophageal Squamous Cell Carcinoma Treated with Preoperative Chemotherapy/Chemoradiotherapy.
Article in Annals of surgical oncology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundA previous study conducted a transcriptome analysis of paired normal and esophageal squamous cell carcinoma (ESCC) tissue samples. The results showed that the expression of serine protease 27 (PRSS27) was perturbed in tumor samples. Hence, this retrospective study aimed to validate the prognostic significance of PRSS27 in patients with preoperative treatment for ESCC.
methodsWe enrolled 86 patients who received preoperative treatment before esophagectomy for ESCC. The expression of PRSS27 in resected ESCC and biopsy tissue samples obtained before preoperative treatment was evaluated via immunostaining, and its relationship with clinicopathological features and prognosis was analyzed.
resultsIn normal esophageal mucosa tissue samples, PRSS27 was expressed in the cytoplasm of spinous cells in the suprabasal layer and basal cells in the basal layer. Of 64 resected ESCC tissue samples, 35 (54.7%) expressed PRSS27 and 29 (45.3%) did not. Moreover, ectopic nuclear expression of PRSS27 was observed. Based on multivariate analysis, PRSS27 expression in resected tumor samples was a predictor of poor prognosis. In cases in which PRSS27 expression was observed in biopsy samples, patients with PRSS27-negative resected tumors had a better postoperative prognosis than those with PRSS27-positive resected tumors.
conclusionsPRSS27 expression in resected ESCC tissue samples is a poor prognostic factor in ESCC patients with preoperative treatment. Furthermore, conversion of PRSS27 expression from positive in biopsy samples to negative in resected tumor samples is a predictor of good prognosis in these patients. Hence, PRSS27 status is an effective tool for decision making regarding adjuvant treatment in ESCC patients.
