Abstract
Background
Regenerating gene 1A (REG1A) plays an important role in tissue regeneration and in cell proliferation in the mucous membrane of the gastrointestinal tract. We previously reported that the positive expression status of REG1A was predictive of chemoradiosensitivity in patients treated with preoperative chemoradiotherapy before esophagectomy or with definitive chemoradiotherapy. To further confirm the utility of REG1A as a chemosensitivity marker, we carried out an additional retrospective clinical study aimed at determining whether REG1A is a reliable chemosensitivity marker in patients treated with esophagectomy followed by adjuvant chemotherapy.
Method
A total of 177 patients with T2–4 thoracic esophageal squamous cell carcinoma received curative surgery without preoperative treatment at Akita University Hospital between 2001 and 2011. A tissue microarray was constructed, and REG1A expression status was analyzed immunohistochemically. We then statistically analyzed the relationships between REG1A expression status and 5-year overall survival (OS), disease-specific survival (DSS), and disease-free survival (DFS).
Results
In the adjuvant group (n = 105), REG1A-positive patients showed significantly better prognoses than REG1A-negative patients. (5-year OS, p = .0022; DSS, p = .0004; and DFS, p = .0040). However, there were no significant differences between REG1A-positive and REG1A-negative patients in the surgery group (n = 72). Univariate and multivariate analyses showed REG1A expression status to be a significant prognostic factor affecting 5-year DSS, comparable to lymph node metastatic status.
Conclusion
The present study suggests REG1A expression status has the potential to be a highly reliable and clinically useful chemosensitivity marker in patients treated with advanced thoracic esophageal squamous cell carcinoma. REG1A expression status will provide a good indication of treatment strategy and enable more individualized treatment for patients.
