There is controversy regarding the best way to prevent recurrences of primary spontaneous pneumothorax (PSP) in children. The purpose of this study was to evaluate the efficacy of video-assisted thoracoscopic surgery (VATS) for pediatric PSP. We retrospectively reviewed patients under 29 years of age who underwent VATS for PSP between March 2005 and(More)
Benign metastasizing leiomyoma is very rare and usually occurs in women who undergo hysterectomy and myomectomy for uterine leiomyoma. This is a benign spindle-shaped smooth muscle cell tumor pathologically but metastasizes to the extrauterine organs. Lungs are the most common site of metastasis. We observed three cases of pulmonary benign metastasizing(More)
BACKGROUND Recent studies demonstrated that miR-137 is downregulated in various tumors, and that it functions as a tumor suppressor. miR-137 could be silenced by its aberrant promoter hypermethylation. The purpose of this study was to investigate the significance of MIR137 promoter methylation on its expression in lung cancer. METHODS Lung cancer cell(More)
BACKGROUND Pulmonary adenocarcinoma (PA) is the most common histologic type of primary lung cancer. Generally, adenocarcinoma was composed by five major components. The present study aimed to evaluate changes in the composition of adenocarcinoma components as the tumor grows; in addition, to analyze the correlation between the occupancy rates of histologic(More)
PURPOSE To analyze the benefit and feasibility of this procedure compared with those of open method. METHODS Abdominal procedure includes laparoscopic gastric mobilization, celiac axis lymph node dissection, formation of the gastric tube, and pyloromyotomy. The actual procedure performed during open surgery is the same as those of laparoscopic surgery(More)
PURPOSE This study was conducted to observe the outcomes of postoperative radiotherapy (PORT) with or without concurrent chemotherapy in resected non-small cell lung cancer (NSCLC) in single institution. MATERIALS AND METHODS From 2002 to 2013, 78 patients diagnosed with NSCLC after curative resection were treated with radiotherapy alone (RT, n = 48) or(More)
Benign esophageal tumors are uncommon, leiomyomas being the most frequent. However, esophageal schwannomas are exceedingly rare. We report here on two instances of large esophageal schwannomas treated by enucleation. A 63-year-old male and a 32-year-old female were referred to us for abnormal chest X-rays. Computed tomography of the chest documented(More)
OBJECTIVE Compensatory hyperhidrosis is one of the most common and serious adverse effects following sympathectomy. We performed a local anesthetic procedure that predicts the occurrence and severity of compensatory hyperhidrosis, and evaluated the feasibility, safety, and efficacy of the procedure. METHODS AND METHODS From July 2009 to July 2010, 20(More)
BACKGROUND Pure ground-glass opacity (GGO) on computed tomography (CT) is considered a diagnostic feature of noninvasive lung adenocarcinoma. However, pure GGO can sometimes be associated with invasive adenocarcinoma (IA). The purpose of this study was to determine the predictive factors for IA when pure GGO is present. METHODS Between 2011 and 2014, 83(More)
BACKGROUND Sublobar resection is considered controversial for non-small cell lung cancer (NSCLC) presenting as a solid-predominant nodule. The aim of this study was to identify risk factors related to recurrence in small-sized NSCLC presenting as a solid-predominant nodule. METHODS We conducted a retrospective chart review of 118 patients who were treated(More)
