Clinical significance of preoperative carcinoembryonic antigen level in patients with clinical stage IA non-small cell lung cancer.

Background: The objective of this study was to assess the preoperative serum carcinoembryonic antigen (CEA) level in patients with clinical stage IA non-small cell lung cancer (NSCLC) and to evaluate its clinical significance.

Methods: Between January 2005 and December 2014, a total of 378 patients with clinical stage IA NSCLC underwent complete resection with systematic node dissection. The survival rate was estimated starting from the date of surgery to the date of either death or the last follow-up by the Kaplan-Meier method.

Thymectomy via a subxiphoid approach: single-port and robot-assisted.

Background: We have previously reported on single-port thymectomy (SPT), which involves performing thymectomy via a single subxiphoid incision, and trans-subxiphoid robotic thymectomy (TRT), which is performed using the da Vinci surgical system. The aim of this study was to investigate the early surgical outcomes of thymectomy using the SPT and TRT subxiphoid approaches and to discuss their appropriate uses.

Methods: The subjects included 80 patients who underwent thymectomy via a subxiphoid approach.

Repeat pulmonary resection for recurrent lung metastases from colorectal cancer: an analysis of prognostic factors.

Objectives: The purpose of this study was to investigate the prognostic factors for repeat lung metastasectomy in patients with colorectal cancer, which may be clinically helpful in defining a subset of patients who are most likely to benefit from repeat lung metastasectomy.

Methods: In total, 138 patients underwent complete lung resection for the first time due to metastases of colorectal cancer between January 2004 and December 2013 at Fujita Health University School of Medicine. Among them, 33 underwent repeat pulmonary metastasectomy for lung tumour recurrence.

Video-Assisted Thoracoscopic Pulmonary Metastasectomy in Patients with Colorectal Cancer: A Recent 10-Year Single-Institution Experience.

Introduction: The purpose of this study was to identify independent unfavorable prognostic factors for patients who underwent video-assisted thoracoscopic surgery for resection of pulmonary metastases from colorectal cancer (CRC).

Methods: Between January 2004 and December 2013, 131 patients with pulmonary metastases from CRC underwent the aforementioned procedure for the first time at our institution. Kaplan-Meier survival curves and log-rank tests were used to analyze the survival rates.

Video-assisted thoracoscopic thymectomy versus subxiphoid single-port thymectomy: initial results†.

Objectives: Compared with conventional median sternotomy, approaches used in thymectomy for myasthenia gravis and anterior mediastinal tumours have become much less invasive in recent years. We previously developed a surgical technique called single-port thymectomy (SPT) to excise the thymus through a single opening made below the xiphoid process. In this study, to show the utility of SPT, we compared factors contributing to low surgical invasiveness between SPT and conventional video-assisted thoracoscopic surgery (VATS) thymectomy.
