sort unique children

I want to list my latest forum topics on the first page. Currently I use the fetch code below, but I get same topic back serveral times. How can i sort uniquelly in my node so that only one forum_reply from each forum_topic will be listed?

    {def $children = fetch('content', 'tree', hash('parent_node_id', 321, main_node_only, true(), class_filter_type, 'include', class_filter_array, array('forum_topic'), sort_by, array('modified', false()), limit,10 ))}

I have tried that, but the problem is that every forum_reply has already a unique main_node_id.
