Objective: To analyze the clinical outcome of concurrent chemoradiotherapy in superficial esophageal cancer patients. Methods: We retrospectively analyzed data for 123 patients with superficial esophageal cancer who received external beam radiotherapy without intracavitary brachytherapy plus systemic chemotherapy during 1998-2015. Elective nodal irradiation was not performed. The dosage to planning treatment volume was 60 Gy in 30 fractions. The main outcome measure was overall survival. Results: Patient characteristics were as follows: median age, 66 (41-83) years; male/female ratio, 106/17; squamous cell carcinoma/other, 122/1; cT1a/cT1b, 27/96; cervical esophagus/upper thoracic esophagus/middle thoracic esophagus/lower thoracic esophagus, 7/9/66/41 and concurrent chemoradiotherapy/radiotherapy alone, 100/23. Cisplatin and 5-fluorouracil were the most commonly used agents (85%). At the last follow-up (median 60.5 months), 91 (74%) patients were alive. Complete response was achieved in 116 (94.4%) patients. The 5-year overall survival, progression-free survival and local control rates were 77.0, 46.9 and 62.7%, respectively, similar to that in the elderly patients (P = 0.878, 0.754 and 0.648, respectively). There were 55 failures: 42 local, 10 regional and 3 distant failures. Nine local and seven regional failures developed out-of-field. Thirty-eight local failures (90%) were successfully salvaged, of which 30 (71%) were salvaged via endoscopic removal; only 2 regional failures (20%) were salvaged. Fifteen G3 acute toxicities occurred. One pneumonitis (G3), one pneumothorax (G3) and two pericardial effusion (G2) were the late toxicities observed. There were no G4 toxicities or treatment-related deaths. Conclusions: Concurrent chemoradiotherapy without intracavitary brachytherapy was effective and safe for superficial esophageal cancer, even in elderly patients.

Background and objectiveThe COPD Assessment Test (CAT) has been reported to have potential utility for measuring health status of idiopathic pulmonary fibrosis (IPF). Although the CAT has been developed for the assessment of COPD patients, it has not been fully evaluated exclusively in IPF. This study was designed to evaluate the validity of the CAT in IPF.
MethodsThe clinical data for 106 consecutive subjects with newly diagnosed IPF who completed pulmonary function tests, partial pressure of oxygen in arterial blood (PaO2 ) at rest, 6-min walk test (6MWT), CAT, St George's Respiratory Questionnaire (SGRQ), modified Medical Research Council (mMRC) dyspnoea grade and Hospital Anxiety and Depression Scale (HADS), were analysed. We assessed the validity of the CAT in comparison with the SGRQ.
ResultsThe present subjects showed mild to moderate restrictive impairment on spirometry. Mean CAT score and total SGRQ were 12.88.0 and 30.817.7, respectively. The concurrent validity of the CAT score in comparison with the SGRQ total score was significant (r=0.72, P<0.001). Internal consistency (Cronbach's =0.869) and repeatability over 3months (intraclass correlation coefficient=0.742) of the CAT were also significant. Single regression analysis showed that the CAT had significant construct validity. In multiple regression analysis, mMRC, PaO2 at rest, minimum SpO(2) during 6MWT and anxiety of HADS were independent predictors for the CAT.
ConclusionsThe CAT is a valid health status measurement in IPF patients. Multiple regression analysis showed that the CAT was significantly correlated with dyspnoea severity, oxygenation impairment and anxiety.
The validity of the COPD Assessment Test (CAT) was evaluated exclusively in idiopathic pulmonary fibrosis (IPF) patients in comparison with the St George's Respiratory Questionnaire (SGRQ). The CAT had a significant correlation with SGRQ and was independently predicted by dyspnoea severity, oxygenation impairment and anxiety.

Diazinon is an organophosphorus (OP) insecticide and is widely used not only in agriculture but also homes and garden in Japan. Diazinon has been reported to increase TNF-alpha production in rat serum and brain, suggesting that it can modify the proinflammatory response. In this study, we investigated the effects of diazinon on macrophage functions, such as cytokine production, reactive oxygen species (ROS) generation, cyclooxygenase (COX)-2 and inducible nitric oxide synthase (iNOS) expressions, cell-surface molecule expressions, and phagocytosis in RAW264.7 cells. In RAW264.7 cells, diazinon induced the production of TNF-alpha and IL-6. Diazinon induced ROS generation and the expressions of COX-2, iNOS, and cell-surface molecules CD40, CD86, and MI-IC class II, but reduced phagocytic activity in RAW264.7 cells. ERIC and p38, but not JNK and p65 were involved in diazinon-induced IL-6 expression in RAW264.7 cells. We also examined these proinflammatory responses in bone marrow-derived macrophages (BMDM) and bronchoalveolar lavage fluid (BALF) cells. These results suggested that diazinon can activate macrophages and enhance inflammatory responses. (C) 2017 Elsevier B.V. All rights reserved.
