Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Sublobar resection (removal of less than one lobe of lung) consists of either segmentectomy or wedge resection of lung.
Segmentectomy refers to identifying and cutting the specific blood supply and airway to the particular segment of the lobe of lung containing the lung cancer. The procedure takes 2-3 hours.
Wedge resection refers to calculating a margin of normal tissue that allows full removal of the cancer, then removing that from the lobe of the lung using a cutting stapler. The procedure takes about one hour.
Sublobar resection can be done through a thoracotomy (large cut on the side of the chest) or with Video-Assisted Thoracic Surgery (VATS), which uses small incisions and a telescope to achieve the same internal operation.

Summary
Brief summary
Lobectomy (or removal of one of the lobes of the lung) is the standard operation for lung cancer that is amenable to surgery. For patients with insufficient breathing reserve, a sublobar resection (segmentectomy or wedge resection) can be offered as it involves the removal of much less lung. The question that surgeons do not know the answer to is how much lung needs to be removed to completely clear around a small lung cancer at the edge of the lung. It may or may not require the removal of the whole lobe, and this study will determine whether a sublobar resection is as good at controlling the cancer as a lobectomy. This is similar to studies in breast cancer that showed that the whole breast did bot have to be removed to control a small breast cancer.
