    ABSTRACT: This study was conducted to evaluate the efficacy and safety of S-1 in patients with advanced non-small-cell lung cancer (NSCLC), receiving two or more prior chemotherapy regimens. S-1 was administered orally for 14 consecutive days, followed by a 7-day rest period. This treatment course was repeated until disease progression or intolerable toxicity occurred. From 2010 to 2012, 45 patients were enrolled in this study. Of the 45 patients, 4 patients [8.9 %, 95 % confidence interval (CI) 0.6-17.2 %] exhibited a partial response and 24 patients (53.3 %) exhibited stable disease. The disease control rate was 62.2 % (95 % CI 48.1-76.4 %). Median progression-free survival was 71 days, and median survival time was 205 days. Four patients had grade 3 hematological toxicities, but toxicities of grade 4 were not observed in this study. Although S-1 monotherapy as third-line treatment or beyond was well tolerated, the response rate for this regimen did not demonstrate sufficient activity for patients with advanced NSCLC.

    ABSTRACT: Bronchology Global Case ReportsSESSION TYPE: Global Case ReportPRESENTED ON: Tuesday, October 29, 2013 at 01:30 PM - 02:30 PMINTRODUCTION: In the stent placement for the airway stenosis under the glottis, T-tube stent is generally chosen in order to prevent migration. However, the problem is that tracheotomy is required to place the T-tube stent and it decreases the QOL of the patient.CASE PRESENTATION: It was the case of a 74-year-old man, who was seen in our clinic because of respiratory discomfort. In the bronchoscopic examination, a polyp narrowing about 80% of the lumen under the glottis was found, and he was diagnosed as squamous cell carcinoma by biopsy. Since he refused surgery, after we performed endoscopic polypectomy, we added radiation treatment(external irradiation:60Gy, intracavitary irradiation:10Gy). For the subsequent recurrence, we repeatedly performed endoscopic tumor resection, but we became no longer able to control the enlargement of the tumor, so we decided to place a stent. Though we recommended the placement of T-tube to the patient, he refused it because of the necessity of tracheotomy. Then we tried to place a DUMON stent(φ14mm, 45cm long) in the narrowed area under the glottis and fix it to the trachea with sutures. First, we inserted two needles into the stent through the body surface of the neck. We led a loop thread from the needle in the proximal side into the stent and led the other nylon thread from the needle in the distal side into the stent. We endoscopically used forceps to pull the thread into the loop and pull it with the loop out to the body surface and ligated them on the neck.DISCUSSION: This time's procedure is very simple and can be easily performed by anyone once they get used to it. This procedure is easier than the traditional one in which people perform a tracheotomy on the narrowed area and insert a T-tube there, and the patient burden is also much reduced.CONCLUSIONS: The method in which people endoscopically use sutures to fix a DUMON stent to the trachea for the airway stenosis under the glottis proved very useful because it can maintain the QOL of the patient after therapy.Reference #1: 3DISCLOSURE: The following authors have nothing to disclose: Hibiki Kanda, Shinichi Iwamoto, Mitsuhiro Tada, Emiko Nishikawa, Toru Kadowaki, Masahiro Kimura, Kanako Kobayashi, Toshikazu Ikeda, Shuichi YanoNo Product/Research Disclosure Information.

    ABSTRACT: Despite initial dramatic response, epidermal growth factor receptor (EGFR) mutant lung cancer patients always acquire resistance to EGFR-tyrosine kinase inhibitors (TKIs). Gatekeeper T790M mutation in EGFR is the most prevalent genetic alteration underlying acquired resistance to EGFR-TKI, and EGFR mutant lung cancer cells are reported to be addictive to EGFR/Akt signaling even after acquired T790M mutation. Here, we focused on Akt kinase-interacting protein1 (Aki1), a scaffold protein of PI3K (phosphoinositide 3-kinase)/PDK1 (3-phosphoinositide-dependent protein kinase)/Akt that determines receptor signal selectivity for non-mutated EGFR, and assessed its role in EGFR mutant lung cancer with or without gatekeeper T790M mutation. Cell line-based assays showed that Aki1 constitutively associates with mutant EGFR in lung cancer cells with (H1975) or without (PC-9 and HCC827) T790M gatekeeper mutation. Silencing of Aki1 induced apoptosis of EGFR mutant lung cancer cells. Treatment with Aki1 siRNA dramatically inhibited growth of H1975 cells in a xenograft model. Moreover, silencing of Aki1 further potentiated growth inhibitory effect of new generation EGFR-TKIs against H1975 cells in vitro. Aki1 was frequently expressed in tumor cells of EGFR mutant lung cancer patients (53/56 cases), including those with acquired resistance to EGFR-TKI treatment (7/7 cases). Our data suggest that Aki1 may be a critical mediator of survival signaling from mutant EGFR to Akt, and may therefore be an ideal target for EGFR mutant lung cancer patients, especially those with acquired EGFR-TKI resistance due to EGFR T790M gatekeeper mutation.Oncogene advance online publication, 8 October 2012; doi:10.1038/onc.2012.446.

    ABSTRACT: We report a patient with Cryptococcus (C.) neoformans infection, who developed a case of sarcoid-like reaction (SLR). There have been reports of SLRs associated with malignancies. Although differentiating sarcoidosis from SLR is difficult, the patient was diagnosed as SLR because propionibacterium acnes bacterial (PAB) antibody staining of biopsy specimens was negative and the chest radiological findings improved after antifungal treatment. To our knowledge, this is the first report of SLR occurring during cryptococcal infection, and we believe that cryptococcal infection should be considered as a potential cause of SLR.

    ABSTRACT: Isoniazid (H) or rifampicin (R) mono-resistant disease can be treated easily and effectively with first-line drugs, while combined H and R resistance (ie, multidrug-resistant tuberculosis (MDRTB)) requires treatment with at least four agents, including a quinolone and an injectable agent. Drug-resistant Mycobacterium tuberculosis strains are reported to be extremely difficult to cultivate invitro. The authors report a case of MDRTB that required 2 years for diagnosis, and was detected only in sputum culture on solid medium. Physicians should consider MDRTB if TB is suspected but pathogens are not detected.

    ABSTRACT: We report a case of long-standing sinobronchial syndrome complicated by microscopic polyangiitis (MPA) during the clinical course. The patient showed a mild elevation of myeloperoxidase antineutrophil cytoplasmic antibody (MPO-ANCA) 17 months prior to the diagnosis of MPA. Subsequently, her MPO-ANCA level gradually became more elevated, and finally her MPO-ANCA level peaked when purpura appeared. Histologic examination of the skin biopsy was consistent with leukocytoclastic vasculitis. Based on the pathological and clinical findings, a diagnosis of MPA was made. Corticosteroid therapy finally led to a remission of MPA with normalized MPO-ANCA titers.

    ABSTRACT: We herein present the first case of pulmonary actinomycosis caused by Actinomyces cardiffensis (A. cardiffensis). A computed tomography (CT) examination revealed a nodule with cavitation in the left upper lobe of the lung. One month later, the lesion had almost disappeared, but a new nodule with peripheral consolidation had appeared in the right middle lobe. Because organizing pneumonia was suspected, prednisolone was begun and improvement was seen. However, two months after the initiation of corticosteroid administration, a chest CT scan showed a lung abscess. The patient underwent surgical resection of the abscess. A. cardiffensis was identified by an amplified 16S ribosomal DNA restriction analysis of a pus sample.

    ABSTRACT: To clarify the clinical features of nontuberculous mycobacteriosis (NTM) complicated with chronic pulmonary aspergillosis (CPA), we analyzed 257 cases diagnosed with newly developed NTM during the last 12 years in our hospital. Fifty-six per cent of the patients were females. Ten cases (3.9%) of them were complicated with CPA in their clinical course. Mean age at the diagnosis of CPA was 65.5 years, and 8 of 10 cases were males. The average period from the diagnosis of NTM to CPA was almost 7 years. Six NTM cases were classified as the cavitary type and 4 as the nodular-bronchiectasis type. At the time of the diagnosis of CPA, NTM bacilli were isolated in 5 cases, but in the other 5 bacilli were not detected. Radiologically it was found that in many cases the infiltrative shadow had increased and the cavity wall had thickened. Antifungal drug administration was effective in 67% of the cases. In particular, in cases with progressive infiltrative shadows, the antifungal drug was effective in 83% of patients. For the clinical management of NTM, careful attention to the complication of CPA is required.

    ABSTRACT: A 77-year-old-man who had been treated for chronic obstructive pulmonary disease (COPD) was referred to our hospital for further examination of a chest X-ray abnormality. The chest X-ray showed consolidation in the right upper and middle lung field. Chest computed tomography showed an airspace consolidation extending subpleurally and nonsegmentally without nodular lesions. The tentative diagnosis was cryptogenic organizing pneumonia. However, bronchoalveolar lavage fluid was positive for acid-fast bacilli on smear and also positive for tuberculosis PCR, leading to a diagnosis of tuberculous pneumonia. Tuberculous pneumonia in COPD patients can be non-segmental and mimic organizing pneumonia.

    ABSTRACT: The interaction between prostate cancer cells and osteoblasts is critical for the development of bone metastasis. Metastatic cancer cells may physically contact osteoblasts in the bone microenvironment; however, the biological significance of this interaction is not fully understood. Human prostate cancer cells (the osteolytic cell line PC-3 and the osteoblastic cell line MDA-PCa 2b) and human osteoblasts (hFOB1.19) were cocultured under two different conditions (bilayer and contact conditions). Differential gene expression profiles of prostate cancer cells were then investigated using microarray analysis. Differentially expressed genes were analysed using RT-PCR and western blotting, and the effect of anti-cadherin neutralising antibodies on their expression was assayed. The osteoclastogenic activity of cells grown under these different conditions was also investigated using an in vitro assay. When PC-3 or MDA-PCa 2b cells were cocultured with hFOB1.19 cells under contact conditions, the expression of eight genes was upregulated and that of one gene was downregulated in PC-3 cells compared with gene expression in bilayer culture. No differentially expressed genes were detected in MDA-PCa 2b cells. Four of the eight upregulated genes (interleukin-1β (IL-1β), cyclooxygenase-2 (COX-2), IL-6 and the third component of complement (C3)) have already been reported to participate in osteoclastogenesis. Indeed, a cell lysate of PC-3 cells grown under contact coculture conditions significantly enhanced osteoclastogenesis in vitro (P<0.005). neutralisation of cadherin-11 with a specific antibody inhibited upregulation of COX-2 and C3 mRNA in PC-3 cells. In contrast, neutralisation of N-cadherin induced upregulation of COX-2 mRNA. Physical contact between osteolytic prostate cancer cells and osteoblasts may upregulate osteoclastogenesis-related gene expression in prostate cancer cells and enhance osteoclastogenesis. Additionally, cadherin-11 and N-cadherin are involved in this process. These data provide evidence supporting new therapies of prostate cancer bone metastasis that target direct cancer-cell-osteoblast cell-cell contact.

    ABSTRACT: On December 6, 2008, a 52-year-old man presented to a clinic with chronic cough, sputum, and chest discomfort, which had lasted since mid-November. Since the chest radiograph showed a small cavity with small nodules and granular shadows, he was referred to another hospital. On TB-PCR, the gastric juice was positive. Therefore, on December 16, 2008, treatment for pulmonary tuberculosis was initiated with isoniazid, rifampicin, ethambutol, and pyrazinamide. However, on February 4, 2009, a drug susceptibility test revealed that the bacilli were resistant to isoniazid and rifampicin. Therefore, he was referred to our hospital. At that time, he had no symptoms and his sputum smear was negative. We performed a right upper lobectomy. The smear result of the surgical specimen was heavily positive (equivalent to Gaffky 6), and the drug susceptibility test showed resistance to ethambutol in addition to isoniazid and rifampicin. After surgery, we treated him with pyrazinamide, streptomycin, para-aminosalicylate, ethionamide, and levofloxacin. We report this case of multidrug-resistant tuberculosis without past treatment who acquired additional resistance to ethambutol during the first 2 months of chemotherapy. When treating multidrug-resistant tuberculosis, very careful consideration of susceptibility to other drugs is warranted.

    ABSTRACT: After new criteria for discharge from a tuberculosis ward were introduced, we studied changes in the length of hospitalization before and after adoption of these criteria. We evaluated monthly data on hospitalization in our tuberculosis ward between April 2003 and September 2008. Although the number of complicated patients increased, hospitalization decreased after the change in discharge criteria. After adoption of the new discharge crite-ria, the length of hospitalization in our tuberculosis ward decreased.

    ABSTRACT: We retrospectively evaluated the clinical usefulness of desensitization therapy for many patients showing allergic reactions to anti-mycobacterial drugs (INH and RFP) according to the proposition reported by the Japanese Society for Tuberculosis (JST). Desensitization therapy for anti-mycobacterial drugs was performed according to the propositions of JST for forty-six patients with mycobacterial disease in several hospitals participating in the Chugoku-Shikoku Mycobacterial Disease Committee between January 1999 and December 2009. Adverse reactions occurred as drug-induced skin eruptions in 23 patients, drug-induced fever in 16, and drug-induced fever plus eruption in 7. The causative drugs suggested by the clinical course or DLST were RFP in 30 patients and INH in 16. The clinical effects of desensitization therapy for individual drugs was good in 23 of 30 patients (77%) receiving RFP, and in 13 of 16 (81%) receiving INH. Ten patients showing failure of desensitization included 5 elderly patients and 2 patients with a history of drug allergies. The interval until initiation of desensitization therapy ranged from 5 to 30 days after the disappearance of adverse reactions and the interval until the appearance of adverse reactions during desensitization therapy ranged from 3 to 18 days. A comparative study between the patient group with successful desensitization therapy and that with failure of desensitization did not show any significant differences except for the interval until initiation of desensitization therapy. We confirmed the clinical effectiveness of desensitization therapy for anti-mycobacterial drugs according to the propositions of JST in this multicenter study.

    ABSTRACT: We report a case of pulmonary capillary hemangiomatosis-like foci (PCH-like foci), presenting as multiple ground-glass opacities (GGOs) on high resolution computed tomography (HRCT). The patient underwent a left lingual segmentectomy to make a definite diagnosis of these GGOs on chest CT. Histological findings were similar to PCH; however, there were no clinical symptoms or findings of pulmonary hypertension. Accordingly, PCH-like foci was diagnosed.

    ABSTRACT: A 80-year-old woman was admitted to our hospital because of left axillary swelling. Needle biopsy specimen showed negative results on a smear for acid-fast bacilli and PCR. The histological findings showed epithelioid cell granuloma with caseous necrosis. QFT TB-2G showed positivity of 1.9 IU/ml in ESAT-6. We diagnosed tuberculous lymphadenopathy and administered antituberculous drugs. After 3 weeks of treatment, in spite of the regression of lymphadenopathy, mammary swelling had progressed. We performed a biopsy of the mammary lesion, but did not detect any abnormal findings. As the mammary lesion had regressed by the continued treatment of antituberculous drugs, we thought the mammary swelling was paradoxical worsening.

    ABSTRACT: An 80-year-old woman was admitted to a local hospital following transient disturbance of consciousness after a fall. High intermittent fever developed after hospitalization and she was diagnosed as having mediastinal abscess with esophageal perforation. She underwent mediastinal drainage and surgical repair of the esophagus. Acid-fast bacilli were detected in her sputum. Chest CT scanning showed a diffuse granular shadow. Then she was diagnosed as having miliary tuberculosis and treated with combination of INH, RFP, EB, and PZA. However, five days after treatment was initiated, fever and skin eruption appeared and treatment has to be stopped after one month. Then she was referred to our hospital. We gradually increased the dosages of INH and RFP, which resulted in pyrexia. Therefore, we changed EB to SM. Fever subsided and we were able to administer the full dose of drugs from the beginning of January 2007. Thereafter, the patient improved gradually. However, she died in February 2007. At autopsy, we identified tuberculous mediastinal lymphadenitis, inflammatory granuloma under the esophageal mucosa and miliary tuberculosis. We report this case as a rare case of miliary tuberculosis and esophageal perforation secondary to tuberculous mediastinal lymphadenitis.

    ABSTRACT: A rare case of chronic obstructive pulmonary disease (COPD) with severe pulmonary hypertension (PH) was found in a 68-year-old man. COPD was diagnosed in his 50s, from which time he received home oxygen therapy. In January 2007, he was admitted due to progression of dyspnea. On admission to our hospital, arterial blood gas analysis showed severe hypoxemia. Moreover, echocardiographic findings demonstrated severe deviation of the interventricular septum toward the left ventricle, with right ventricular dilatation. Cardiac catheterization data demonstrated pulmonary arterial hypertension with a low cardiac output. Because severe PH is uncommon in patients with COPD and there was no apparent etiology of PH other than COPD, we thought this case was predominantly a pulmonary vascular disease such as idiopathic pulmonary arterial hypertension. Though we first treated this patient with bosentan, it was not effective. Therefore, he was treated with continuous infusion of epoprostenol. Epoprostenol administration along with bosentan resulted in decrease of BNP and right ventricular function improvement. We report a case of severe PH due to severe COPD treated with continuous administration of epoprostenol.
