Keyword research is something that should continually evolve. Just because a certain keyword gets a certain amount of search volume each month does not guarantee that you will receive that targeted internet traffic.
Which of your keywords are performing as you expected them to? Which keywords are underperforming? Are you seeing any trends that indicate new keywords (ones you didn’t purposefully target) are delivering a internet traffic to your site?
Search behavior evolves over time, which means keywords that worked well in 2011 might necessarily have the same result 2012.
Don’t be afraid to retarget new keywords, but make sure you are making changes based on your site’s analytics!
