The prognosis of patients with differentiated thyroid cancer is relatively fair, with a 10-year survival rate above 80%. One of the important prognostic factors is cancer invasion to the airway. For the last 25 years we have been performing combined resection of the trachea and larynx and have reported a relatively good 10-year survival (67.7%) and improved(More)
BACKGROUND The purpose of this report is to discuss the appropriate choice of procedures for video-assisted resection of thymoma according to factors such as the presence of myasthenia gravis or location of the tumor. METHODS We evaluated the short-term results of thoracoscopic surgery for 30 consecutive cases of noninvasive thymoma. Unilateral(More)
We examined 116 stage I-IIIA non-small-cell lung cancer (NSCLC) patients for intra-tumoral expression of thymidylate synthase (TS) and dihydropyrimidine dehydrogenase (DPD) using TaqMan reverse transcription polymerase chain reaction (RT-PCR) assay to clarify the correlation between gene expression and the efficacy of 5-fluorouracil (5-FU) in patients with(More)
OBJECTIVE To evaluate the impact on patient survival of video-assisted thoracoscopic surgery (VATS) thymectomy for the treatment of early-stage thymoma, by comparing the intermediate-term oncologic outcomes with outcomes after open thymectomy. METHODS Eighty-two patients who underwent complete resection of a Masaoka stage I or II thymoma between November(More)
Thymidylate synthase (TS) is an enzyme that catalyzes an important DNA biosynthesis process. The gene expression of TS has not been reported in non-small-cell lung cancer (NSCLC) patients. To clarify the correlation between TS mRNA levels and clinicopathological features of NSCLC, we examined 70 Stage I and II NSCLC patients for intra-tumoral expression of(More)
Pseudoaneurysm of the pulmonary artery (PA) induced by Swan-Ganz catheter injury is an important complication with high mortality. We report a case of PA pseudoaneurysm treated by PA repair. A 52-year-old woman developing infiltrate in the right lung field in chest radiography after a second mitral valve replacement was diagnosed with PA pseudoaneurysm(More)
Fourteen years have passed since video-assisted thoracic thymectomy (VATS-T) began to be used to treat diseases of the thymus. Indications for VATS-T have been expanded by ensuring sufficient space for easy endoscope manipulation using the sternum-lifting method. A variety of VATS-T techniques are available, including the cervical approach, bilateral VATS,(More)
We report three cases of meningeal carcinomatosis that metastasized from lung cancer. The patients were men of 73, 65 and 77 years old. The histological type was adenocarcinoma in all cases. At the time of emergence of neurological symptoms such as nausea, headache and cataplexy, enhanced CT of the brain did not disclose brain metastasis. Although brain MRI(More)
An asymptomatic 42-year-old man was diagnosed with a posterior mediastinal mass, most likely a nonfunctioning, benign, neurogenic tumor for which thoracoscopic surgery was initially indicated. However, the systemic blood pressure rapidly increased to a critical level immediately after starting the surgical manipulation of the tumor, which was suggestive of(More)
A 58-year-old man who complained of an abdominal tumor was admitted to our hospital. Abdominal CT scan showed that a 15-cm tumor occupied the entire right upper abdomen and that there were ascites and liver metastases. A liver biopsy was performed. The liver biopsy showed a small cell carcinoma pattern, but no definitive origin of the tumor was determined.(More)
