OBJECTIVES: Non-small-cell lung cancer (NSCLC) patients with chronic obstructive pulmonary disease (COPD) are at an increased risk of pulmonary complications after pulmonary resection. This study aimed to identify whether video-assisted thoracoscopic (VATS) lobectomy can reduce postoperative pulmonary complications compared with lobectomy by thoracotomy in NSCLC patients with COPD. METHODS: Among a total of 1502 NSCLC patients who underwent lobectomy from April 2005 to June 2012 at the Seoul Nat

There is little information about the effectiveness of ciprofloxacin in regions where ciprofloxacin-resistant Escherichia coli is prevalent. This study was conducted to evaluate whether ciprofloxacin is effective as the initial empirical antibiotic for treatment of uncomplicated acute pyelonephritis (APN) due to ciprofloxacin-resistant E. coli. A total of 255 women with clinical diagnoses of uncomplicated APN due to E. coli were enrolled in the emergency department between March 2005 and Decembe

OBJECTIVES: Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) treatment prolongs the progression-free survival of patients with advanced non-small-cell lung cancer harbouring EGFR mutations. This study aimed to evaluate the prognostic factors influencing survival after recurrence, and the effectiveness of EGFR-TKIs in patients with recurrent pulmonary adenocarcinoma after curative resection. METHODS: EGFR mutations were prospectively evaluated in 594 patients who underwent

BACKGROUND: Postoperative leakage after esophagectomy is associated with significant life-threatening complications. Recently, endoscopic vacuum therapy (EVT) was introduced and has been successfully used as a new treatment option. The purpose of this study was to evaluate the safety and efficacy of EVT for the management of postoperative leakage after esophagectomy. METHODS: A total of 22 patients were treated with either intraluminal or intracavitary EVT for the management of postoperative lea

Abstract Background We externally validated the proposed 9th edition of the TNM staging classification with our institution’s prospectively collected data and compared it to the 8th edition for overall survival (OS) and freedom from recurrence (FFR). Methods A retrospective analysis was conducted of 4029 cases of stage I-III non-small cell lung cancer that underwent surgical treatment from January 2004 to December 2020. Survival was compared using Kaplan-Meier curves and multivariable Cox regres

The present study investigated the prognostic role of extranodal extension (ENE) in stage III-N2 non-small-cell lung cancer (NSCLC) following curative surgery. From January 2005 to December 2018, pathologic stage III-N2 disease was diagnosed in 371 patients, all of whom underwent anatomic pulmonary resection accompanied by mediastinal lymph node dissection. This study included 282 patients, after excluding 89 patients who received preoperative chemotherapy or incomplete surgical resection. Their

OBJECTIVES: The purpose of this study was to analyse the prognostic significance of the dominant features of ground-glass opacities (GGOs) in part-solid node-negative adenocarcinomas with invasive components of similar sizes. METHODS: From 2004 to 2017, a total of 544 patients with a diagnosis of part-solid pathological node-negative adenocarcinoma with an invasive component <20 mm in size were selected. The enrolled patients were categorized into 2 groups: a GGO-dominant [50% < GGO (%) < 100%,
