Figure 1From: Prospective evaluation of serum tissue inhibitor of metalloproteinase 1 and carbonic anhydrase IX in correlation to circulating tumor cells in patients with metastatic breast cancerCorrelation between TIMP-levels (ng/ml) and CAIX levels (ng/ml) subdivided after presence of CTC. CAIX, carbonic anhydrase IX; CTC, circulating tumor cell; TIMP, tissue inhibitor of metalloproteinase.Back to article page
