Abstract:
Objective To evaluate the prognostic value of serum alkaline phosphatase (ALP) and serum lactate dehydrogenase (LDH) levels in stage Ⅰ-Ⅲ breast cancer patients before and after treatment.
Methods A clinical retrospective analysis was performed with complete data from 476 stage Ⅰ-Ⅲ breast cancer patients who received treatment in the Department of Oncology of Guizhou Cancer Hospital from 2003 to 2012. The median follow-up time was 61 months. Patients' serum levels of ALP and LDH were detected before and within one week after treatment and then their relationship with recurrence and metastasis rates, PFS and OS were analyzed.
Results For stageⅠ-Ⅲ breast cancer patients, OS and PFS in the high ALP level group after treatment were significantly shorter than those in the low ALP level group(P < 0.05). The PFS in the high LDH level group after treatment was significantly shorter than that in the low LDH level group (P < 0.05). The relapse/metastasis rate in the high LDH level group after treatment was significantly higher than that in the low LDH level group(P < 0.05).
Conclusion ALP and LDH levels after treatment could be used as the prognostic factors for OS and PFS of stage Ⅰ-Ⅲ breast cancer patients. LDH level after treatment could provide some reference for recurrence and metastasis.
