Views : Rewrite results - Edit content
You can in views rewrite the result of any field, or trim most fields, but if there is some logic to what you want to remove you would need to do with with a preprocess hook in your theme. In this case it sounds like you need to do the latter. Something like this should do the trick:

function theme_preprocess_views_view_fields(&amp;$vars) {
  if ($do_your_checks) {
    $vars['fields']['field_name'] = preg_replace(...) // Use regular expression to change title.
  }
}
