Induction of Kallikrein-Related Peptidase 13 and TET2/3 by Anticancer Drugs and Poor Prognosis of Patients with Esophageal Squamous Cell Carcinoma After Preoperative Treatment.

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
backgroundPreoperative chemotherapy/chemoradiotherapy has been generally considered for the treatment of esophageal squamous cell carcinoma (ESCC) to improve prognosis. We examined the effects of anticancer drugs on the expression of kallikrein-related peptidase 13 (KLK13), a potential ESCC prognostic marker, and its clinical relevance in patients who received chemotherapy/chemoradiotherapy for ESCC.
methodsOverall, 105 patients with ESCC who received chemotherapy or chemoradiotherapy before esophagectomy were enrolled. The expression of KLK13 in biopsy samples obtained before chemotherapy/chemoradiotherapy and resected ESCC tumors was assessed by immunohistochemical staining. The effects of 5-fluorouracil (5-FU) and/or cisplatin (CDDP) exposure on the expressions of KLK13 and ten-eleven translocation dioxygenases (TET) in ESCC cells were examined by reverse transcription-polymerase chain reaction.
resultsImmunohistochemical staining of paired ESCC specimens before (biopsy samples) and after (resected specimens) chemotherapy/chemoradiotherapy demonstrated a change in KLK13 expression. KLK13 and TET2/3 transcriptions were induced when human ESCC cell lines were treated with 5-FU and/or CDDP. Among patients with KLK13-negative status before chemotherapy/chemoradiotherapy, those with KLK13-positive resected tumors had a significantly poorer prognosis than those with KLK13-negative resected tumors (p = 0.0477). By using tumor cells isolated from ESCC biopsy tissues obtained before chemotherapy/chemoradiotherapy, we established a primary culture system and detected the induction of KLK13 expression by anticancer drugs.
conclusionsPreoperative treatments alter KLK13 expression in ESCC. The conversion of KLK13 expression from a negative status in biopsy samples to a positive status in resected tumor samples is a predictor of poor prognosis. KLK13 status is a potential marker for decision making to avoid harmful chemotherapy/chemoradiotherapy in patients with ESCC.
