Exisulind-induced apoptosis in a non-small cell lung cancer orthotopic lung tumor model augments docetaxel treatment and contributes to increased survival.

We reported previously a significant increase in survival of nude rats harboring orthotopic A549 human non-small cell lung cancer tumors after treatment with a combination of exisulind (Sulindac Sulfone) and docetaxel (D. C. Chan, Clin.

Exisulind in combination with docetaxel inhibits growth and metastasis of human lung cancer and prolongs survival in athymic nude rats with orthotopic lung tumors.

Docetaxel, a semisynthetic taxane, improves the survival of stage IIIB and IV non-small cell lung cancer patients. However, the 5-year survival remains poor, and few patients experience a complete remission. In this report, we evaluated the effects of exisulind, a novel proapoptotic agent that is a sulfone metabolite of sulindac, in combination with docetaxel on the growth of the human non-small cell lung cancer cell line A549 in vitro and in vivo.

Preclinical and clinical studies of docetaxel and exisulind in the treatment of human lung cancer.

Lung cancer is the leading cause of cancer death in the United States. The majority of patients with non-small cell lung cancers present with inoperable disease because of the presence of metastases to regional lymph nodes or other metastatic sites. About one third of patients have stage IV disease with metastases to distant organs at the time of diagnosis.
