However, several recent immunohistochemical studies revealed that a low MIB-1 index is a good prognostic marker in patients with PC. We report the case of a patient with PC and a single brain metastasis that(More)
OBJECTIVES Combined pulmonary fibrosis and emphysema (CPFE) is a unique disorder that is usually diagnosed on the basis of high resolution computed tomography (HRCT) findings. It is unclear whether CPFE is an independent prognostic factor in patients with non-small-cell lung cancer (NSCLC). Therefore, we conducted a retrospective analysis to assess the(More)
We report the rare case of delayed hemothorax (DHX) with an inferior phrenic artery (IPA) injury due to blunt thoracic trauma. Our case suggests that DHX almost always occurs early after injury, and endovascular treatment is an effective procedure for traumatic hemothorax including DHX.
We experienced an extremely rare case of a thymoma in the middle mediastinum. A 42-year-old woman presented with a 4-cm-sized abnormal mass in the middle mediastinum by chest computed tomography. To resect this tumor, we performed surgery using the thoracoscopic lateral approach from the right side subsequently followed by a median sternotomy. After the(More)
