I'm chronic hepatitis b carrier. i tried treatment but no avail. what're chances of getting liver failure or cirrhosis?

Actually low risk: Being a carrier confers little risk of liver failure/cirrhosis/cancer, but chronic, active hepb has a higher risk. Since you did not hve luck with therapy, the best you can do is nuture your liver--avoid/minimize alcohol/drugs, get vaccinated for hepa, eat a healthy, balanced diet along with maintaining ideal body wt (obesity increases risk), and follow-up with doc regularly. Good luck.

Chronic treatment: I'm not sure what you mean by "carrier" and "no avail." it sounds like you have chronic hepatitis b. This is not a curable infection, but can be treated using life-long anti-hbv medications. The goal is to maintain an undetectable HBV dna, and to try to get conversion from hbeag to hbeab. I'm not sure why this wouldn't have worked for you.
