Improved therapeutic effectiveness by combining recombinant CXC chemokine ligand 10 with Cisplatin in solid tumors.
Clin Cancer Res. 2005 Jun 01; 11(11):4217-24.CC

Abstract

PURPOSE

CXC chemokine ligand 10 (CXCL10) is a potent inhibitor of angiogenesis. We wonder whether the combination of CXCL10 with cisplatin would improve the therapeutic antitumor efficacy.

EXPERIMENT DESIGN

We evaluated the antitumor activity of the combination therapy in the immunocompetent C57BL/6 and BALB/c mice bearing LL/2 Lewis lung cancer and CT26 colon adenocarcinoma, respectively. Mice were treated with either CXCL10 s.c. at 25 mug per kg per day once daily for 30 days, cisplatin cycled twice (5 mg/kg i.p. on days 14 and 21 after the initiation of CXCL10), or both agents together. Tumor volume and survival time were observed. Antiangiogenesis of CXCL10 in vivo were determined by alginate capsule models and CD31 immunohistochemistry. Histologic analysis and assessment of apoptotic cells were also conducted in tumor tissues.

RESULTS

CXCL10 + cisplatin reduced tumor growth in LL/2 and CT26 tumor model, respectively, more effectively, although cisplatin or CXCL10 individually resulted in suppression of tumor growth and improved survival time of tumor-bearing mice. CXCL10 successfully inhibited angiogenesis as assessed by alginate model and CD31 (P < 0.05). Histologic analysis of tumors exhibited that CXCL10 in combination with cisplatin led to the increased rate of apoptosis, tumor necrosis, and elevated lymphocyte infiltration.

CONCLUSIONS

Our data suggest that the combination of CXCL10, a well-tolerated angiogenesis inhibitor, with cisplatin can enhance the antitumor activity. The present findings may be of importance to the further exploration of the potential application of this combined approach in the treatment of lung and colon carcinoma.
