抄録 Although cisplatin-based chemotherapy shows a survival advantage compared to carboplatin for treating advanced non-small cell lung cancer, high-volume hydration and a long infusion time are necessary to avoid nephrotoxicity, and cisplatin-based chemotherapy has been difficult to administer in outpatient settings. A low-volume hydration method using mannitol or furosemide as forced diuresis was recently introduced, but there are no clear conclusions regarding which agent should be used. We describe our ongoing randomized phase II trial (the OLCSG1406 Study) evaluating the efficacy of forced diuresis. This study will clarify whether mannitol or furosemide is more suitable in cisplatin-based chemotherapy with low-volume hydration.

抄録 In very-elderly diffuse large B-cell lymphoma (DLBCL) patients, treatment intensities must be lowered due to the risks of comorbidities and organ function deterioration, and treatment outcomes are worse compared to younger patients. Very-elderly patients are often excluded from DLBCL clinical trials, and optimal treatments and dosages are not established. In this clinical trial, we examined the efficacy and safety of 6 courses of R-mini CHP therapy (cf., CHOP [cyclophosphamide, doxorubicin, vincristine, and prednisone]) in which vincristine is omitted to avoid the peripheral neuropathy that reduces elderly patients’ quality of life, as remission induction therapy in DLBCL patients aged≥80 years.

抄録 Pulmonary tumor thrombotic microangiopathy (PTTM) is a fatal, malignancy-related respiratory complication; we herein report a PTTM case induced by metastatic prostate cancer. An 81-year-old Japanese man developed dyspnea. High-resolution computed tomography (HRCT) revealed ground-glass opacities spread across bilateral lung fields. Pulmonary microvascular aspiration cytology detected prostate cancer cells. As PTTM was highly suspected, docetaxel chemotherapy was performed immediately. His respiratory condition and HRCT findings improved temporarily, but he died approx. 6 weeks after admission. Autopsy showed fibrocellular intimal proliferation of small pulmonary arterioles, which confirmed the diagnosis of PTTM induced by prostate cancer. As in the present case, it is often difficult to confirm the presence of not only tumor embolization but also fibrocellular intimal proliferation before the patient’s death.

抄録 Renal involvement is occasionally observed in Wiskott-Aldrich syndrome (WAS) and X-linked thrombocytopenia (XLT). It has been reported that galactose-deficient IgA is a closely linked to IgA nephropathy (IgAN), suggesting that patients with XLT/WAS associated with reduced galactosylation on serum IgA are susceptible to IgAN. It is necessary to pay more attention to patients with IgAN due to the potential complication with XLT/WAS. We here present a patient of XLT complicated with mild IgAN who underwent tonsillectomy combined with steroid pulse therapy to achieve complete clinical remission.

抄録 A healthy 10-year-old boy vomited during sleep and later complained of abdominal pain; he became drowsy and uncommunicative. At the nearby hospital E.R., he deteriorated rapidly, and his respiratory movements were absent with cardiac arrest. He was immediately resuscitated. Brain MRI showed no abnormalities. EEG revealed an abnormal pattern with recurrent multifocal epileptiform activity over the bilateral occipital and frontal regions during sleep. Based on the clinical/radiological findings we diagnosed Panayiotopoulos syndrome (PS), a benign form of early-onset pediatric epilepsy characterized by autonomic symptoms. Lifethreating cardiopulmonary arrest is rare in PS, but long seizure duration of PS may associate with apnea and bradycardia.

抄録 We compared 11C-choline and FDG PET/CT scan findings for the staging and restaging of prostate cancer. Twenty Japanese prostate cancer patients underwent 11C-choline and FDG PET/CT before (n=5) or after (n=15) treatment. Using a five-point scale, we compared these scanning modalities regarding patient- and lesion-based diagnostic performance for local recurrence, untreated primary tumor, and lymph node and bony metastases. Of the 20 patients, documented local lesions, and node and bony metastases were present in 11 (55.0%), 9 (45.0%), and 13 (65.0%), respectively. The patient-based sensitivity/specificity/accuracy/area under the receiver-operating-characteristic curve (AUC) values for 11C-choline-PET/CT for diagnosing local lesions were 90.9% /100%/ 95.0% / 1.0, whereas those for FDG-PET/CT were 45.5% /100%/ 75.0% / 0.773. Those for 11C-choline-PET/CT for node metastasis were 88.9% /100%/ 95.0% / 0.944, and those for FDG-PET/CT were 44.4%/100%/75.0%/0.722. Those for 11C-choline-PET/CT for bone metastasis were 84.6%/100%/90.0%/0.951, and those for FDG-PET/CT were 76.9% /100%/ 85.0% / 0.962. The AUCs for local lesion and node metastasis differed significantly (p=0.0039, p=0.011, respectively). The lesion-based detection rates of 11C-choline compared to FDG PET/CT for local lesion, and node and bone metastases were 91.7% vs. 41.7%, 92.0% vs. 32.0%, and 94.8% vs. 83.0% (p=0.041, p=0.0030, p<0.0001), respectively. 11C-choline-PET/CT is more useful for the staging and restaging of prostate cancer than FDG-PET/CT in Japanese men.

抄録 We investigated whether a small amount of blood collected by fingertip blood sampling would be adequate in a mass examination for hepatitis virus infection in Japan. A cross-sectional survey was conducted at health fairs in Kasaoka City and Shodoshima Island, where participants took the hepatitis screening test. A total of 114 consecutive individuals who took the hepatitis screening test were enrolled. Twenty microliters of plasma was successfully obtained from all participants. Among the participants, two had positive results for HBs antigen and two were positive for anti-HCV; all four were > 60 years old and rarely visited the hospital. Thirty-three and 38 patients chronically infected with HBV and HCV, respectively, were examined for confirmatory assays at participating hospitals. All subjects with undetectable serum levels of HBs antigen and anti-HCV had undetectable levels of both markers in fingertip blood, and the levels in serum and fingertip blood were significantly correlated (p<0.01). The lower detection limit of HBs antigen was defined as 0.005 IU/ml, and the cut-off value of anti-HCV was 1.0 by using 10-μl fingertip blood samples. The fingertip blood sampling described herein may be adequate in mass examinations for hepatitis virus testing in Japan.

抄録 Lympho-epithelial Kazal-type-related inhibitor (LEKTI) is a large multidomain serine protease inhibitor that is expressed in epidermal keratinocytes. Nonsense mutations of the SPINK5 gene, which codes for LEKTI, cause Netherton syndrome, which is characterized by hair abnormality, ichthyosis, and atopy. A single nucleotide polymorphism (SNP) of SPINK5, p.K420E, is reported to be associated with the pathogenesis of atopic dermatitis (AD). We studied all 34 exons of the SPINK5 gene in Japanese 57 AD patients and 50 normal healthy controls. We detected nine nonsynonymous variants, including p.K420E; these variants had already been registered in the SNP database. Among them, p.R654H (n=1) was found as a heterozygous mutation in the AD patients, but not in the control. No new mutation was detected. We next compared the data of the AD patients with data from the Human Genetic Variation Database provided by Kyoto University; a significant difference was found in the frequency of the p.S368N genotype distribution. PolyPhen-2 and SIFT, two algorithms for predicting the functional effects of amino acid substitutions, showed significant scores for p.R654H. Therefore, R654H might be a risk factor for epidermal barrier dysfunction in some Japanese AD patients.

抄録 We validated a navigator-echo-triggered sequence that drives magnetization before cardiac-gated inversion recovery T1 turbo field echo acquisition, in the sedated free-breathing pediatric population. Cardiac magnetic resonance imaging was performed on sedated infants with single ventricle. We calculated the signal-to-noise ratios and contrast-to-noise ratios of 2 groups of images obtained using respiratory triggering with and without navigator echo. All images were then visually assessed by 2 observers. The signal-to-noise ratio and the contrast-to-noise ratio were significantly higher with than without navigator echo (p<0.01; p<0.05). The visual assessment scores were also consistently better with than without navigator echo (p<0.01). Free-breathing navigator echo was found to have the advantage of decreasing the motion artifact caused by respiration. Cardiacgated inversion recovery T1 turbo field echo sequence for free-breathing navigator-echo-triggered respiration allows for the acquisition, in sedated infants, of diagnostic images whose quality exceeds that of the non-navigator-echo-triggered alternative.

抄録 Several research groups demonstrated that ‘a disintegrin-like and metalloproteinase with thrombospondin type 1 motifs (ADAMTS)’-family proteases play roles in cancer progression. However, the origins and contributions of these proteases are not known. Here, we demonstrate an association between host-produced ADAMTS4 and early-stage tumor growth. Murine Lewis lung carcinoma (LLC) tumors showed marked expressions of Adamts4 and Adamts5. We examined the contributions and distributions of host-derived Adamts4 and Adamts5 on tumor growth, using Adamts4LacZ/LacZ and Adamts5LacZ/LacZ knockout mice. Interestingly, the Adamts4LacZ/LacZ mice showed enhanced tumor growth compared to wild-type mice at 5-, 10- and 12-days post-inoculation, whereas the Adamts5LacZ/LacZ mice did not show significant differences in tumor growth. We next examined LacZ distribution in LLC tumor-bearing Adamts4LacZ/LacZ mice by β-galactosidase (β-gal) staining. We found that the β-gal-positive signals were strictly localized at the interior areas of the tumor at 10 days post-inoculation. Multiple staining demonstrated that most of the β-gal-positive cells were localized at the tumor vasculature in Adamts4LacZ/LacZ mice. Interestingly, β-gal-positive signals were not co-localized with biglycan after 10 days post-inoculation, excluding the biglycan cleavage by host-derived ADAMTS4. Taken together, these findings illustrate that host-derived ADAMTS4 was expressed at the tumor vessels and was associated with early-stage tumor growth.

抄録 To investigate megakaryocyte (MK) DNA ploidy in various hematological diseases, fluorescence microscopy imaging system (FMI) can be used to analyze DNA ploidy with cell morphology at the single-cell level by using specialized image-processing software. Here we compared DNA ploidy obtained by FMI measured with that obtained flow cytometry (FCM). With FMI, we could evaluate the DNA ploidy in long-term preserved bone marrow smear samples after staining. We next analyzed the MK DNA ploidy in 42 bone marrow smear samples including 26 myeloid neoplasm cases, and we compared the DNA ploidy and platelet counts in the patients' peripheral blood; the production of platelets was significantly high compared to DNA ploidy in the myeloproliferative neoplasms group. The FMI method revealed that the patients with 5q- syndrome exhibited relatively low DNA ploidy despite high platelet counts, and this result suggested that increased DNA ploidy is not indispensable to abundant platelet production. The FMI method for DNA ploidy will be a useful tool to clarify the relationship between DNA ploidy and platelet production by MKs.

抄録 We retrospectively analyzed the factors related to postoperative cardiovascular (CV) events in patients undergoing partial nephrectomy (PN) or radical nephrectomy (RN) for clinical T1 renal cell carcinoma (RCC). We identified 570 patients who underwent PN or RN for T1 renal cell carcinoma between January 1998 and December 2009 at our institution and related hospitals. We determined the cumulative incidence rate of CV events and overall survival (OS) using Kaplan-Meier survival curves with a log-rank test, and we evaluated the risk for an increase in CV events and OS using Cox proportional hazard regression. Of the 570 patients, 171 underwent PN and 399 underwent RN. The type of surgery was not significantly related with CV events. The only factor that significantly increased the risk of CV events in both the univariate (HR 2.67, p=0.006) and multivariate analyses (HR 2.14, p=0.044) was a postoperative estimated glomerular filtration rate (eGFR) <45 ml/min/1.73 m2. Postoperative eGFR was also a significant risk factor for OS in the univariate analysis (HR 2.38, p=0.0104), but not in the multivariate model. Postoperative renal function was a significant independent predictor of the incidence of subsequent CV events.

抄録 The bacterium Vibrio alginolyticus, an opportunistic pathogen in humans, has a type III secretion system (T3SS) that is responsible for its cytotoxicity toward eukaryotic cells. The effector of T3SS that is responsible for the cytotoxicity had not been identified. Here we demonstrate that VepA, a homolog of the T3SS effector in V. parahaemolyticus, is required for cytotoxicity in V. alginolyticus. VepA induces lysosomal membrane permeabilization, and it allows the leakage of only small molecules into the cytosol. Our findings revealed that VepA induces cathepsin-independent cell death in mammalian cells. The ferrous ion, one of the small molecules in the lysosome contents, appears to be involved in the cell death caused by V. alginolyticus VepA.

抄録 Lipoprotein(a), or Lp(a), is a low-density lipoprotein-like particle largely independent of known risk factors for, and predictive of, cardiovascular disease (CVD). We investigated the association between baseline Lp(a) levels and the progression of coronary artery calcification (CAC) in patients with hypercholesterolemia undergoing statin therapy. This study was a sub-analysis of a multicenter prospective study that evaluated the annual progression of CAC under intensive and standard pitavastatin treatment with or without eicosapentaenoic acid in patients with an Agatston score of 1 to 999, and hypercholesterolemia treated with statins. We classified the patients into 3 groups according to CAC progression. A total of 147 patients (mean age, 67 years; men, 54%) were analyzed. The proportion of patients with Lp(a) > 30 mg/dL significantly increased as CAC progressed (non-progression; 5.4%, 0<CAC progression ≦100; 7.7%, and CAC progression >100; 23.6%). Logistic regression analysis showed that Lp(a) > 30 mg/dL was an independent predictor of the annual change in Agatston score > 100 (OR: 5.51; 95% CI: 1.28-23.68; p=0.02), even after adjusting for age, sex, hypertension, diabetes mellitus, current smoking, body mass index, and lipid-lowering medications. Baseline Lp(a) >30 mg/dL was a predictor of CAC progression in this population of patients with hypercholesterolemia undergoing statin therapy.

抄録 Neurodegenerative diseases in which tau accumulation plays a cardinal role in the pathogenic process are called tauopathies, and when tau isoforms having four repeats of the microtubule binding sites, four-repeat tau, are selectively accumulated as pathological hallmarks, the term four-repeat tauopathy is used. The major four-repeat tauopathies are progressive supranuclear palsy (PSP), corticobasal degeneration (CBD), and argyrophilic grain disease (AGD). Historically, neuronal cytopathologies, e.g., neurofibrillary tangles and ballooned neurons, were emphasized as characteristic lesions in PSP and CBD. Now, however, astrocytic tau pathologies, i.e., tufted astrocytes (TAs) and astrocytic plaques (APs), are considered to be highly disease-specific lesions. Although granular/fuzzy astrocytes (GFAs) frequently develop in the limbic system in AGD cases, the specificity is not conclusive yet. Some AGD cases have a few TAs, and to a lesser frequency, a few APs in the frontal cortex and subcortical nuclei. The number of astrocytic tau pathologies including TAs and GFAs increases with the progression of AGD. In this paper, histopathological features of astrocytic tau pathologies in PSP, CBD, and AGD are first reviewed. Then, recent findings regarding the coexistence of these tauopathies are summarized from a viewpoint of astrocytic tau pathologies. Further biochemical and pathological studies focusing tau-positive astrocytic lesions may be useful to increase understanding of the pathological process in four-repeat tauopathies and to develop novel therapeutic strategies for patients with these diseases.

抄録 We treated two patients with a rare metaplastic carcinoma of the breast. Patient 1:A 32-year-old woman presented with a rapidly growing mass( 7cm) in her right breast. We diagnosed cT3N0M0 Stage IIB breast cancer and performed a radical resection. The pathological diagnosis was triple-negative metaplastic carcinoma with a Ki-67 value >30%. Postoperative adjuvant chemotherapy and radiotherapy were performed. Patient 2:A 66-year-old postmenopausal woman presented with a left breast mass. We diagnosed cT1N0M0 Stage I breast cancer and performed a radical resection. The pathological diagnosis was triple-negative metaplastic carcinoma with a Ki-67 value >30%. Postoperative adjuvant chemotherapy was performed. Patients 1 and 2 have achieved relapse-free survivals of 1 year+2 months and 10 months, respectively. Metaplastic carcinoma of the breast is a rare tumor, and its prognosis is not favorable. The only available treatment is that used for invasive ductal carcinoma;a more specific treatment has not been established. The accumulation of further similar cases and the development of a novel effective treatment are desired.

タイトル(別表記) A case of a mesenteric desmoid tumor preoperatively distinguished from imaging findings
著者 河合 毅| 渡邉 貴紀| 信久 徹治 | 松本 祐介| 甲斐 恭平| 佐藤 四三|
抄録  A 73-year-old woman was admitted for closer investigation into an abdominal tumor. Abdominal ultra-sonography, CT, and magnetic resonance imaging showed a discrete abdominal tumor. Especially on MRI, the tumor appeared as a relatively ill-defined whorled soft-tissue thickening within the mesenteric fat, causing angulation or speculation of adjacent bowel mesentery. Surgery was performed under a presumptive diagnosis of a mesojejunum desmoid. The tumor was invading the transverse mesocolon and mesojejunum as well as the third portion of the duodenum and the middle colic artery, and it was close to but apart from the superior mesenteric artery. The tumor was resected, including removal of part of the duodenum and transverse colon. The specimen contained a white solid tumor measuring 14×12×8cm. Pathologic examination showed differentiated fibroblasts and copious collagen fibers. The tumor was negative for CD34, c-kit, S-100, and α-SMA, but positive for β-catenin. On the basis of these findings, we established a diagnosis of mesenteric desmoid tumor of the small intestine. The patient has been followed postoperatively for 2 years, no sign of recurrence, to date.
