BACKGROUND: The presence of multiple metastatic pulmonary nodules is a predictor of poor survival after pulmonary metastasectomy. However, there is a paucity of data addressing the exact number of pulmonary metastases over which prognosis becomes grave. The aim of our study is to investigate the prognosis of pulmonary metastasectomy from colorectal cancer (CRC) depending on the number of pulmonary metastases. METHODS: Patients who had undergone pulmonary metastasectomy for CRC between November 1

BACKGROUND: Patients with malignant pleural effusion have a limited life expectancy. An increase in pleural and oncological treatment options and more accurate prognostic evaluation may help individualize treatment strategies. The aim of this study was to identify the prognostic indicators of overall survival (OS) after video-assisted thoracic surgery (VATS) talc pleurodesis for malignant pleural effusion. METHODS: We examined the medical records of all consecutive patients with malignant pleura

PD-L1 expression is associated with disease stage and type of <i>EGFR</i> mutation. PD-L1 positivity might be associated with worse RFS among patients with surgically treated <i>EGFR</i>-mutant NSCLC.

These preliminary results suggest that non-intubated VATS lung biopsy is a safe and feasible option in patients with ILD.

BACKGROUND: Our objective was to evaluate the influence of liver metastasis on survival after pulmonary metastasectomy in patients with colorectal cancer (CRC). METHODS: We retrospectively reviewed a total of 524 patients and were classified into two groups based on the presence of liver metastasis. Group HM + PM (n = 106) included patients who previously received a hepatic metastasectomy and then received pulmonary metastasectomy. Group PM (n = 418) included patients who only received pulmonary

BACKGROUND: There are several concerns on thoracoscopic surgery for large tumors because of the increased risk of tumor cell spillage. This study aimed to compare perioperative outcomes and oncological validity between video-assisted thoracoscopic surgery (VATS) and open lobectomy for non-small cell lung cancer (NSCLC) with tumor size > 5 cm. METHODS: We retrospectively reviewed 355 patients who underwent lobectomy with clinical N0 NSCLC with solid tumor component diameter > 5 cm between January

OBJECTIVE: To analyze conditional survival estimates of patients with esophageal cancer who underwent curative resection. SUMMARY BACKGROUND DATA: Conditional survival reflects dynamic prognosis updated to the current status and is a more relevant indicator for current healthcare and life decisions. METHODS: This study included 1883 patients who underwent complete resection for esophageal squamous cell carcinoma at a tertiary cancer center from 1994 to 2016. We calculated 5-year (5Y) conditional
