What happened, in summary

This man was treated for Stage II right lower lobe squamous cell lung cancer in the setting of COPD. He had not received neoadjuvant treatment. His surgeons used sleeve right lower lobectomy with systematic lymph-node dissection, removing the cancer-bearing lower lobe while preserving the right middle lobe through bronchial reconstruction. The operation was intended to balance oncologic resection with preservation of pulmonary function. More than a year after surgery, his measured lung function was better than the value predicted for a lower bilobectomy and was close to his preoperative level. He remained disease-free through 30 months of follow-up.
