BACKGROUND Although the concept of induction therapy followed by surgical resection for locally advanced non-small cell lung cancer (LA-NSCLC) has found general acceptance, the appropriate indications and the strategy for this treatment are still controversial. METHODS From 2000 through 2008, 36 patients received concurrent chemoradiotherapy followed by(More)
INTRODUCTION Surgery for locally advanced lung cancer is carried out following chemoradiotherapy. However, there are no reports clarifying what the effects on the subsequent prognosis are when surgery is carried out in cases with radiation pneumonitis. In this paper, we report on 2 cases of non-small cell lung cancer with Grade 2 radiation pneumonitis after(More)

PRESENTATION OF CASE A 45-year-old woman with a past history of hydatidiform mole six years previously was found to have a(More)
INTRODUCTION When considering treatment for pulmonary cancer complicated by interstitial pneumonia, the greatest problem is acute exacerbation. We report two cases of pulmonary cancer complicated by interstitial pneumonia in which multiple intrapulmonary lymph nodes were noted. CASE PRESENTATIONS Cases 1 and 2 were 76- and 62-year-old males, respectively.(More)
INTRODUCTION Malignant Peripheral Nerve Sheath Tumor is a rare type of soft tissue malignant tumor that occurs in only 5% of cases. It tends to occur in the arms and legs and trunk of the body, with mediastinal occurrence in only a few cases. Among mediastinal tumors, only 18.8% occur primarily in the nerves, and of these, only 10.3% are malignant, with(More)
Selecting the proper treatment strategy for locally advanced lung cancer, such as T4 tumors, is difficult. Therefore, obtaining an accurate diagnosis of T4 tumors is required. It can be difficult to determine whether the tumor invades adjacent structures. We describe the case of a patient easily diagnosed to be without aortic invasion using cine magnetic(More)
