The JIPANG study is a randomized phase III study of pemetrexed/cisplatin (Pem/Cis) versus vinorelbine/cisplatin (Vnr/Cis) for completely resected stage II-IIIA non-squamous non-small cell lung cancer (Ns-NSCLC). This study did not meet the primary endpoint (recurrence-free survival, RFS) but Pem/Cis had a similar efficacy to Vnr/Cis with a better tolerability. Tumor mutation burden (TMB) is thought to have a predictive value of immune checkpoint inhibitors. However, the relevance of TMB to cytot...

Accidents while using lawn mowers are often reported, but chest injuries are rare. We report a case of a penetrating pulmonary injury due to a rusty nail thrown by a lawn mower. A 63-year-old man injured his left precordium by a thrown object while using a lawn mower; he thereafter visited a nearby hospital. A computed tomography image showed a left-sided pneumothorax and a penetrating pulmonary injury of the left upper lobe due to a foreign body. Pneumothorax was treated with thoracic drainage ...

BACKGROUND Pulmonary resection is occasionally performed in postpneumonectomy patients with contralateral lung lesions, such as metachronous or metastatic lung cancer. Careful intraoperative respiratory management is essential in such patients. This study evaluated the respiratory management of postpneumonectomy patients who underwent contralateral pulmonary resection with selective bronchial blockade of the lobe or segment to be resected. METHODS We retrospectively analyzed the surgical finding...

Double aortic arch (DAA) is a rare congenital anomaly of the heart and aorta in which a vascular ring that surrounds the trachea and esophagus is formed. In most patients, respiratory distress and dysphagia develop in childhood, and asymptomatic adult patients are rarely known. Herein, we describe a patient with lung cancer and DAA. A 66-year-old man who had DAA underwent video-assisted thoracoscopic right upper lobectomy and mediastinal lymph node dissection for primary lung cancer. Lymph node ...

Air leakage is a common complication after pulmonary resection, which is usually caused by direct lung damage during surgery. Herein, we describe a case in which a pulmonary cyst developed rapidly in the right lower lobe and ruptured 10 days after right upper lobectomy. A 49-year-old man, who was a heavy smoker, underwent thoracoscopic right upper lobectomy for primary lung cancer. No air leakage was observed postoperatively, and the chest drain tube was removed on postoperative day 1. Although ...

Abstract Introduction Multilocular thymic cyst (MTC) is a rare condition of an acquired multilocular cystic lesion caused by inflammation and often associated with autoimmune diseases or malignant tumors. We present a patient with MTC and asymptomatic rheumatoid arthritis (RA), which is termed preclinical RA. Presentation of case A 60-year-old man underwent a computed tomography scan, which revealed an 8.5 cm multilocular cystic lesion in the anterior mediastinum. The tumor had a lower intensity...

The diaphragm dissection should be started from anterior, because the portion is just under the thoracotomy incision. The diaphragmatic muscle was cut by an electric knife along the line of 1 to 2 cm from the chest wall from anterior and lateral to posterior. The diaphragm including the tendon center is dissected from the peritoneum. The peritoneum should be preserved. If the peritoneum is opened, it should be repaired by sutures. The pericardium is opened at the apex. The pericardium incision i...
