Purpose:
We examined the interaction between cyclophosphamide (CPA) and angiostatin (AS) on the growth of primary Lewis lung carcinoma (LLC) tumors and on the development of LLC pulmonary metastases. We studied the effects of AS and CPA on the stages of angiogenesis employing in vitro assays.
Methods:
Primary tumor growth and pulmonary metastases were measured to evaluate the effects of treatment with AS alone, CPA alone or the combination of CPA and AS. We examined the effects of CPA plus AS on endothelial cell (HUVEC) survival, migration and tube formation.
Results:
Combined treatment with CPA and AS did not significantly affect primary tumor growth when compared with CPA treatment alone. However, a significant decrease in the number of pulmonary metastases was observed following CPA plus AS treatment when compared with CPA treatment alone ( P<0.001). AS did not enhance CPA-mediated HUVEC cytotoxicity, and CPA failed to enhance AS-mediated inhibition of migration. However, tube formation was inhibited following combined treatment with CPA and AS when compared with either treatment alone.
Conclusions:
AS enhanced the antimetastatic effects of CPA without significantly influencing the effects of CPA on primary tumor growth. CPA plus AS inhibited tube formation, suggesting that interrupting specific steps in the angiogenesis process might be an effective approach to the treatment of subclinical distant metastases.
