- Purpose: PRL-3 (phosphatase of regenerating liver) is involved in metastasis of colorectal cancer; however, its therapeutic implication in cancer patients has not been studied. We investigated the relationships of PRL expression to radiotherapy (RT) in rectal cancer patients.Methods and Materials: Phosphatase of regenerating liver expression was immunohistochemically examined in distant (n = 36) and adjacent (n = 82) normal mucosa, primary tumor (n = 125), biopsy specimens (n = 96), and lymph node metastasis (n = 30) from rectal cancer patients participating in a clinical trial of preoperative RT.Results: Phosphatase of regenerating liver expression was increased from the distant to adjacent mucosa and to the primary tumor (p < 0.05). PRL was highly expressed at the invasive margin in 28% of the primary tumors and 26% of the metastases. In the RT group, strong PRL expression at the invasive margin was related to distant recurrence (p = 0.006) and poor survival (p = 0.01), but not in the non-RT group. The survival significance remained even after adjusting for Dukes’ stage and differentiation (p = 0.02). Additional multivariate analyses showed that the correlation with prognostic significance of PRL differed between the RT and non-RT groups (p = 0.01).Conclusion: Phosphatase of regenerating liver expression (rather than PRL-3 alone) at the invasive margin predicted resistance to RT and unfavorable survival in rectal cancer patients with preoperative RT.
