Figure 4From: High serum alkaline phosphatase cooperating with MMP-9 predicts metastasis and poor prognosis in patients with primary osteosarcoma in Southern ChinaOverall survival curves were stratified by pre-ALP levels according to surgery style, Post-chemotherapy, metastasis and local recurrence after surgery. Kaplan-Meier curves shows that the patients with high pre-ALP levels have poorer OS independent of surgery type (a, b), Post-chemotherapy (c, d), metastasis (e, f) and local recurrence after surgery (g, h).Back to article page
