Uses of prostacyclin analogs
The present invention provides a method for preventing or reducing the risk of cancer or the progression of premalignant dysplasia in a subject having a higher risk factor by administering a therapeutically effective amount of prostacyclin analog.
1. A method for reducing a risk of developing lung cancer in a human former smoker, said method comprising administering a therapeutically effective amount of prostacyclin analog comprising iloprost to the former smoker such that the risk of developing lung cancer in the former smoker is decreased by at least 10% relative to a control group with the similar risk factor.
2. The method of claim 1 , wherein the former smoker averaged at least 1 pack of cigarettes per day for at least 5 years.
3. The method of claim 1 , wherein the risk of developing cancer in the subject is decreased by at least 20% relative to the control group.
4. A method for reducing a risk of developing premalignant lung dysplasia in a human former smoker, said method comprising administering a therapeutically effective amount of prostacyclin analog comprising iloprost to the former smoker such that the risk of premalignant lung dysplasia progression in the former smoker is decreased by at least 10% relative to a control group with the similar risk factor.
5. The method of claim 4 , wherein the progression of premalignant dysplasia in the former smoker is decreased by at least 20% relative to the control group.
