To address the major issue of regional disparity in the treatment for elderly cancer patients in an aging society, we compared the treatment strategies used for elderly patients with thoracic esophageal cancer and their survival outcomes in metropolitan areas and other regions. Using the national database of hospital-based cancer registries in 2008-2011, patients aged 75 years or older who had been diagnosed with thoracic esophageal cancer were enrolled. We divided the patients into two groups: those treated in metropolitan areas (Tokyo, Kanagawa, Osaka, Aichi, Saitama, and Chiba prefectures) with populations of 6 million or more and those treated in other areas (the other 41 prefectures). Compared were patient backgrounds, treatment strategies, and survival curves at each cancer stage. In total, 1236 (24%) patients from metropolitan areas and 3830 (76%) patients from nonmetropolitan areas were enrolled. Patients in metropolitan areas were treated at more advanced stages. There was also a difference in treatment strategy. The 3-year survival rate among cStage I patients was better in metropolitan areas (71.6% vs. 63.7%), and this finding mainly reflected the survival difference between patients treated with radiotherapy alone. For cStage II-IV patients, there were no differences. Multivariable Cox proportional hazard analysis including interaction terms between treatment areas, cStage, and the first-line treatments revealed that treatments in the metropolitan areas were significantly associated with better survival among patients treated with radiotherapy alone for cStage I cancer. Treatment strategies for elderly patients with thoracic esophageal cancer and its survival outcomes differed between metropolitan areas and other regions. 相似文献
Japanese patients with interstitial lung disease (ILD) sometimes die waiting for lung transplantation (LTx) because it takes about 2 years to receive it in Japan. We evaluated nutrition‐related factors associated with waiting list mortality. Seventy‐six ILD patients were hospitalized in Kyoto University Hospital at registration for LTx from 2013 to 2015. Among them, 40 patients were included and analyzed. Patient background was as follows: female, 30%; age, 50.3 ± 6.9 years; body mass index, 21.1 ± 4.0 kg/m2; 6‐minute walk distance (6MWD), 356 ± 172 m; serum albumin, 3.8 ± 0.4 g/dL; serum transthyretin (TTR), 25.3 ± 7.5 mg/dL; and C‐reactive protein, 0.5 ± 0.5 mg/dL. Median observational period was 497 (range 97‐1015) days, and median survival time was 550 (95% CI 414‐686) days. Survival rate was 47.5%, and mortality rate was 38.7/100 person‐years. Cox analyses showed that TTR (HR 0.791, 95% CI 0.633‐0.988) and 6MWD (HR 0.795, 95% CI 0.674‐0.938) were independently correlated with mortality and were influenced by body fat mass and leg skeletal muscle mass, respectively. It is suggested that nutritional markers and exercise capacity are important prognostic markers in waitlisted patients, but further study is needed to determine whether nutritional intervention or exercise can change outcomes. 相似文献
Treatment response in obsessive–compulsive disorder (OCD) is heterogeneous and the neurobiological underpinnings of such variability are unknown. To investigate this issue, we looked for differences in brain structures possibly associated with treatment response in children with OCD. 29 children with OCD (7–17 years) and 28 age-matched controls underwent structural magnetic resonance imaging. Patients then received treatment with fluoxetine or group cognitive-behavioral therapy during 14 weeks, and were classified as treatment responders or non-responders. The caudate nucleus, thalamus and orbitofrontal cortex were selected a priori, according to previous evidence of their association with OCD and its treatment. Gray matter (GM) volume comparisons between responders, non-responders and controls were performed, controlling for total GM volume. 17 patients were classified as responders. Differences among responders, non-responders and controls were found in both caudate nuclei (both p-values = 0.041), but after Bonferroni correction for multiple comparisons, these findings were non-significant. However, after excluding the effect of an outlier, findings were significant for the right caudate (p = 0.004). Pairwise comparisons showed larger caudate GM volume in responders versus non-responders and controls, bilaterally. The right caudate accounted for 20.2% of the variance in Y-BOCS changes after treatment in a linear regression model, with a positive correlation (p = 0.016). We present a possible neural substrate for treatment response in pediatric OCD, which is in line with previous evidence regarding the caudate nucleus. Considering the limitations, further research is needed to replicate this finding and elucidate the heterogeneity of treatment response in children with OCD (National Clinical Trials Registration Number: NCT01148316).
Portal venous gas is occasionally encountered in children with intestinal pneumatosis, identified on real‐time ultrasound imaging as hyperechoic foci with quick movement. The origin of the portal venous gas can be identified by following the hyperechoic foci along the branches of the portal vein, providing an estimate of the location of intestinal pneumatosis. This approach may be useful for predicting the patient's prognosis. Our report describes 2 cases of portal venous gas while estimating the area of intestinal pneumatosis, which were evaluated with real‐time ultrasound. 相似文献
Systemic sclerosis‐associated interstitial lung disease (SSc‐ILD) is the most frequent cause of death for SSc but there is still no sufficient treatment available. Although cyclophosphamide (CYC) therapy is a common treatment which has shown statistical efficacy against SSc‐ILD to date, its effects are temporary and not enough. Rituximab (RTX), the anti‐CD20 monoclonal antibody, has recently shown efficacy in many autoimmune diseases. In SSc‐ILD, RTX is also considered to be one of the novel treatment candidates. However, studies of SSc‐ILD in Japanese treated with RTX have only a few case reports. Therefore, in this study, we retrospectively compared nine patients treated with RTX and 30 patients treated with CYC to investigate the efficacy of RTX treatment for Japanese anti‐topoisomerase I‐positive SSc‐ILD patients. At the 24‐month evaluation, the improvement rates of percent predicted of forced vital capacity and percent predicted of diffusing capacity of the lung carbon monoxide in the RTX‐treated group were significantly higher than those in the CYC‐treated group (20.6 ± 8.8% vs 1.1 ± 3.9%; P < 0.05 and 34.0 ± 6.0% vs ?1.5 ± 2.8%; P < 0.01, respectively). In addition, skin thickness scores also showed a marked improvement from 13.5 points before the start of treatment to 5.8 points after 24 months by RTX therapy (P < 0.05). These results suggest that RTX treatment is more effective for Japanese SSc‐ILD patients than CYC treatment. In the future, it is expected that large‐scale clinical trials will show the usefulness of RTX treatment for SSc‐ILD. 相似文献
The carcinogenesis and development of prostate cancer are mediated by enhanced Ca2+ signaling. In the present study, the pharmacological profile of the Ca2+-sensing receptor (CaSR) antagonists (calcilytics) was examined in human prostate cancer PC-3 cells. NPS2143 and Calhex 231 blocked extracellular Ca2+-induced increases in cytosolic [Ca2+]. NPS2143 and Calhex 231 inhibited cell proliferation (IC50 = 7.4 and 10.3 μM, respectively) and migration. The exposure to NPS2143 or Calhex 231 down-regulated CaSR protein expression. These results demonstrated that calcilytics inhibited cell proliferation/migration and down-regulated CaSR expression in human prostate cancer cells, suggesting their potential as novel therapeutic drugs for prostate cancer. 相似文献
