The 10-year study adds evidence that supports a new standard to preserve lung tissue in cancer patients whenever possible. 697 patients with peripheral stage 1 tumors less than 2 centimeters in size were randomly assigned to undergo a lobectomy or a sublobar resection, where part of the cancerous lobe is removed. In the latter, patients received either...
