Survival impact of unexpected N2 in stage IIIB/N2 non-small cell lung cancer patients.

Background: We investigated the effect of unexpected N2 on survival in stage IIIB/N2 cases.

Methods: We retrospectively analyzed 1803 non-small cell lung cancer patients between 2010 and 2016. There were 89 patients (4.

Comparison of short-term results of subxiphoid and conventional video-assisted thoracoscopic surgery in diagnostic wedge resections.

Background: This study aimed to compare early results in patients who underwent subxiphoid wedge resection with those operated on using a multiportal approach.

Methods: We retrospectively evaluated 151 patients who underwent diagnostic wedge resection for suspected interstitial lung disease. Patients who underwent wedge resection via subxiphoid video-assisted thoracoscopic surgery and conventional video-assisted thoracoscopic surgery were compared.

Correlation between outcomes and tumor size in >7 cm T4 non-small cell lung cancer patients: A tumor size-based comparison study.

Background: We investigated whether all size-based pathological T4N0-N1 non-small cell lung cancer patients with tumors at any size >7 cm had the same outcomes.

Methods: We reviewed non-small cell lung cancer patients with tumors >7 cm who underwent anatomical lung resection between 2010 and 2016. A total of 251 size-based T4N0-N1 patients were divided into two groups based on tumor size.
