    Background. Acute pulmonary thromboembolism (APTE) is increasing in Japan. Semiquantification of the number of segments with perfusion defect by ^<99m>Tc-MAA SPECT might allow us to predict aggravation to chronic thromboembolic pulmonary hypertension (CTPH). Purpose. To assess the significance of serial semi-quantitative studies by ^<99m>Tc-MAA SPECT in patients with APTE. Methods. We enrolled 26 patients who had been given a diagnosis of APTE by means of CT pulmonary angiography and/or pulmonary angiography between 2002 and 2006. All patients underwent ^<133>Xe gas ventilation/^<99m>Tc-M A A perfusion SPECT studies or perfusion SPECT study only, every 6 to 12 months, twice or more. Results. Of the 26 patients with APTE, 18 (26.9%) improved after thrombolytic treatment with reduction in mean numbers of perfusion defect segments from 6.75 to 2.80. Complete resolution of embolism on 99mTc-MAA SPECT following the thrombolysis was seen in only 4 patients (15.4%) with APTE. On the other hand, 7 patients with APTE exhibited deterioration or no change, and one showed both improvement and deterioration in the serial SPECT studies. Thus, 8 patients (30.8%) had no improvement of pulmonary perfusion on the serial SPECT studies despite thrombolytic treatment. Conclusion. We believe that serial ^<99m>Tc-MAA SPECT studies are useful in monitoring semi-quantitative assessment of pulmonary perfusion defects and of aggravation to CTPE after thrombolytic treatment.

    Positron emission tomography (PET) using ^<18>F-fluorodeoxyglucose (FDG) enables cancer imaging based on the elevated glucose metabolism of malignant cells. The usefulness of FDG-PET has been demonstrated in the differential diagnosis of lung nodules, accurate staging through the detection of whole body metastasis, and sensitive detection of recurrence after therapy. Recently, the advantages of PET in the management of lung cancer patients has moved from differential diagnosis to staging, and to detection of recurrence, because of the advancement of multi-detector CT and PET-CT technology. Accurate diagnosis using FDG-PET is helpful for the selection of the most appropriate therapy.

    Cancer screening with FDG-PET has increased recently but the detection rate for lung cancer is not high, and PET-negative cases are frequently seen. The detection rate in our institution was 0.22% (20 cases out of 9282 PET studies) during 4 years and half, and 40% were PET-negative cases which were found out by CT. PET-negative cases consisted of those showing GGO on CT, BAG and well differentiated adenocarcinoma, and stage I. The accumulation rate was not high even in PET-positive cases, and only 25% cases detected showed high FDG concentration. Almost all false positive cases were inflammatory diseases. The importance and issues of FDG-PET for lung cancer screening are discussed.

    Purpose. We evaluated the efficacy of respiratory endoscopy on subjects requiring further detailed examinations as a result of initial asbestos-related disease screening. Methods. The subjects consisted of 132 participants who underwent asbestos-related disease screening in our hospital between July 2005 and March 2006. According to their history of screening, the participants were classified into the initial screening group and the second screening group. The former consisted of 76 participants without prior screening, while the latter consisted of 56 participants who were referred to our hospital for the detailed examinations as a result of initial screening undergone elsewhere. The participants were examined concerning their history of asbestos exposure, and then underwent chest X-ray followed by chest computed tomography (CT). Respiratory endoscopic examinations were mainly performed in participants with suspected chest malignancies. Results. There were no significant differences in the distribution of age or gender between the two screening groups. In both screening groups, more than 70% of the participants had a history of occupational exposure to asbestos. Radiological abnormalities were observed in 110 (83%) of all participants. Asbestos-related diseases were detected in a total of 90 (68%) cases. The breakdown of the 90 cases by disease was as follows: 60 cases had pleural plaque, 13 pulmonary fibrosis, 5 lung cancer (LC), 4 benign asbestos pleurisy, 4 round atelectasis, 2 diffuse pleural thickening, and 2 malignant pleural mesothelioma (MPM). The disease detection rate of LC and MPM was 3.8% and 1.5%, respectively. Respiratory endoscopic examinations were performed in a total of 15 cases. The breakdown of the 15 cases by examination was as follows: bronchoscopy was performed in 6 cases, thoracoscopy including video-assisted thoracoscopic surgery (VATS) in 8, and mediastinoscopy in 4. Two cases with early LC were diagnosed by videothoracoscopic lung biopsy. A diagnosis of MPM was made by pleural biopsy under VATS. There were no examination-related complications. Conclusion. Respiratory endoscopic examinations should be actively performed in participants with suspected chest malignancies as a result of asbestosrelated disease screening, because the procedure has a high diagnostic rate and can be safely performed.

    Background. Endobronchial granular cell tumor (GCT) is rare. Only 57 cases have been reported in Japan. Case. An abnormal shadow was pointed out on a chest X-ray film taken during regular treatment for bronchial asthma in a 62-year-old woman. We found a 10-mm in diameter nodular lesion in her left hilum with consolidation in left S^3 by CT scanning. Bronchofiberscopy revealed a nodular lesion with a granular surface at the orifice of left B^3. The biopsy specimen contained many cells with a low N/C ratio and which were positive for anti S-100 and anti NSE antibody. We made a diagnosis of GCT and resected the left upper lobe. Although the origin of GCT is still unknown, it has been suggested that GCT is derived from Schwann cell, because many GCT cases are positive for anti S-100 antibody in Japan. Almost all GCT cases in Japan occurred in lobar or larger bronchi, but the real pathogenesis is unknown. Conclusion. We reported a case of endobronchial GCT. We examined this case and other such cases reported in Japan, and it is suggested that GCT is derived from Schwann cell of peripheral nerves.

    Background. We treated a very rare case of synchronous double cancer consisting of gastric adenocarcinoma and tracheal squamous cell carcinoma. Case. A 72-year-old man presented with gastric adenocarcinoma in the lateroposterior wall of the greater curvature of the middle of the corpus and synchronous squamous cell carcinoma of the carina infiltrating the esophagus. Prior to excision of the gastric adenocarcinoma, CDDP 20 mg/day was administered for 5 consecutive days, and the tracheal carcinoma was irradiated with 60 Gy. After treatment, the tracheal carcinoma and infiltration into the esophagus disappeared completely. Gastrectomy revealed that the gastric tumor was a stage IA well differentiated tubular adenocarcinoma. After surgery, 2 courses of CBDCA + weekly PTX were conducted and 600 mg/day UFT-E was orally administered for 14 weeks. After a 3-year follow-up period, the patient was asymptomatic. Conclusion. Minimally invasive surgical procedures and treatments are considered important for synchronous double cancer. This rare case of tracheal cancer, has shown complete remission for more than 3 years after multidisciplinary treatment.

    Background. We report a case of tracheobronchomalacia positive for anti-type II collagen antibody. Case. A 41-year-old man undergoing medical treatment for bronchial asthma developed wheezing and dyspnea which resulted in emergency hospitalization. Steroid preparation and bronchial dilators were administered, but no improvement in symptoms was seen, so the patient was referred to our hospital. Chest CT revealed severe airway stenosis, which led to a diagnosis of tracheobronchomalacia. Since the anti-type II collagen antibody was positive, the patient was suspected of having relapsing polychondritis and was examined closely, but the results failed to meet the diagnostic criteria for that disease. The patient was treated with steroid preparation and cyclosporine, but had infections repeatedly and died 7 months after admission. Conclusion. Stenosis in the airway should be assessed by CT on inhalation-exhalation to differentiate tracheobronchomalacia in cases of refractory chronic obstructive pulmonary disease.

    Background. The convex transducer enables blood flow visualization by power Doppler mode. There is no doubt that power Doppler improves visualization to distinguish between vesseles and other aechoic structures. Another merit to power Doppler is to visualize vessels in a lymph node. In my initial experiences, metastatic lymph nodes of lung cancer have irregularly winding vessels in lymph nodes, and sarcoidosis and malignant lymphoma have straight vessels in the lymph nodes and linear margins of the lymph node. Purpose. We studied 71 lymph nodes visualized by convex bronchoscope. Study objectives were to evaluate whether images of B mode and power Doppler mode may improve the diagnosis of metastatic or benign lymph nodes. Seventy-one lymph nodes visualized by convex bronchoscope sarcoidosis 13 lymph nodes, malignant lymphoma 2 lymph nodes, and metastasis of lung cancer 56 lymph nodes. Results. Of 61 lymph nodes (LNs) without linear hyperechoic lines between LNs, 56 (92%) were metastatic. Fifty-three (95%) of 56 metastatic LNs had aberrant and winding intranodal vessels. In other words, LNs without linear hyperechoic lines and LNs with aberrant and winding intranodal vessels were metastatic. Eight sarcoidosis and 2 malignant lymphoma had hilar straight vessels and linear hyperechoic lines. Conclusion. Irregularly winding vessels and the absence of linear hyperechoic lines were diagnostic factors for metastatic lymph nodes.
