Trademark a phrase similar to an existing trademark?

I am thinking about applying a trademark for my product name. The name contains two words, say ';WordA WordB';. I searched US patent and trademark website and found an existing trademark, the phrase is ';WordB-WordA';. So basically the reverse order of my two words with a dash. The description of the trademark and business industry is completely different than mine. There is definitely no similarity of the purpose of the phrase. Under such circumstances, do you think I can get mine registered? Thanks a ton!
