AIM: To investigate the angiogenesis status,the expression of vascular endothelial growth factor(VEGF),angiopoietin-1(ANG-1),angiopoietin-2(ANG-2),thrombospondin-1(TSP-1) in cholangiocellular carcinoma(CCC) and relationship with tumor angiogenesis,differentiation,invasion and metastasis.METHODS: 33 specimen of surgically resected CCC were investigated.Immunohistochemical staining of CD34,VEGF,ANG-1,ANG-2 and TSP-1 was carried out.RESULTS: The mean MVD was(87.2?52.6)/mm2.VEGF positive expression was found in 75.6% cases;ANG-1 positive expression was observed in 36% cases;ANG-2 positive was detected in 57.6% cases and 45.5% cases exhibited positive TSP-1 expression.VEGF and ANG-2 expressions were found to be associated with significant higher level of MVD(P

Background:
In Brugada syndrome (BrS), the arrhythmogenic substrate is suggested to be located in the epicardial surface of the right ventricle outflow tract. Postmortem examinations of BrS described epicardial and interstitial fibrosis, the causes of which remain unclear.Case presentation: We present a family in whom the proband is a case of aborted sudden cardiac death from ventricular fibrillation (VF) without spontaneous Brugada-type electrocardiogram, and his mother underwent pacemaker implantation due to sick sinus syndrome. The proband showed recurrent acute pericarditis two consecutive years before the VF episode. These events occurred twice in mid-spring, the same season when the lethal arrhythmia occurred.
Conclusions
This case suggests a possibility in the pathogenesis of epicardial fibrosis of BrS that the RVOT lesions induced by SCN5A mutations have not only fibrotic characteristics but also in some patients, inflammatory characteristics which may be manifested as repeated mild pericarditis or occult pericarditis.

OBJECTIVE: To test the concept of taxane sequencing, this feasibility trial evaluated maintenance of docetaxel after paclitaxel and carboplatin combination chemotherapy in patients with stage IC-IV ovarian cancer. METHODS: All patients received debulking surgery followed by paclitaxel and carboplatin chemotherapy. Attainment of clinically defined complete or partial response was confirmed by image scanning. Maintenance of docetaxel started at an initial dose of 70 mg/m2 every 4 weeks for 6 cycles and was extended to 10 cycles unless disease progression and/or recurrence during the protocol therapy or unacceptable toxicities were seen. RESULTS: Stage subsets in 20 eligible patients were as follows: IIIB, 2 patients (10%); IIIC, 13 patients (65%); IV, 5 patients (25%). Neutropenia was common (40% with grade 3 or 4) and was most frequent during first or second cycle although the disabling peripheral neuropathy was not observed. Twelve patients completed protocol therapy (6< or =cycles), while 8 patients failed to complete 6-cycle chemotherapy, because of progressive disease (5 patients) or grade 4 toxicities (3 patients). Median PFS was 20 months and 3-year PFS rate was 12%. Median overall survival was 39 months and 3-year OS rate was 69%. CONCLUSION: Six cycles of single-agent docetaxel maintenance chemotherapy is feasible and generally tolerable to women with advanced ovarian cancer who attained a clinically defined response to initial paclitaxel and carboplatin based chemotherapy.

Background/Aims:
A previous study demonstrated that half of patients started oral corticosteroids (OCS) for ulcerative colitis (UC) exacerbations at lower doses than recommended by Japanese treatment guidelines (initial OCS prednisolone equivalent dose, 30–40 mg). This may relate to physician’s concern about infection, especially pneumonia including Pneumocystis jirovecii pneumonia (PJP), from high OCS doses. We assessed whether pneumonia incidence is increased with guideline-recommended OCS initial doses.
Methods:
This retrospective cohort study used the Japan Medical Data Center claims database (2012–2021). The whole cohort consisted of all UC patients who started OCS during the study period meeting the inclusion and exclusion criteria. The matched cohort was created by propensity score matching; the lower (initial OCS dose < 30 mg), guideline-recommended (30–40 mg), and higher groups ( > 40 mg) in a 2:2:1 ratio. Pneumonia incidence in the primary analysis was evaluated in the matched cohort. A Poisson regression model determined pneumonia-related risk factors in the whole cohort.
Results:
After screening, 3,349 patients comprised the whole cohort; 1,775 patients comprised the matched cohort (lower dose, n = 710; guideline-recommended dose, n = 710; higher dose, n = 355). The incidence of any pneumonia was low; no differences were observed in incidence rates across these dose subgroups. In total, 3 PJP cases were found in the whole cohort, but not detected in the matched cohort. Several risk factors for any pneumonia were identified, including age, higher comorbidities index, treatment in large facility and hospitalization.
Conclusions
The incidence of pneumonia, including PJP, in UC patients was low across initial OCS dose treatment subgroups.

OBJECTIVE: We conducted a retrospective, multi-institutional, collaborative study to accumulate cases of neuroendocrine carcinoma of the endometrium, to clarify its clinicopathologic features, treatment, prognosis and prognostic factors to collate findings to establish future individualized treatment regimens. To our knowledge, this is the largest case study and the first study to statistically analyze the prognosis of this disease. METHODS: At medical institutions participating in the Kansai Clinical Oncology Group/Intergroup, cases diagnosed at a central pathologic review as neuroendocrine carcinoma of the endometrium between 1995 and 2014 were enrolled. We retrospectively analyzed the clinicopathologic features, treatment, prognosis and prognostic factors of this disease. RESULTS: A total of 65 cases were registered from 18 medical institutions in Japan. Of these, 42 (64.6%) cases were diagnosed as neuroendocrine carcinoma of the endometrium based on the central pathological review and thus included in the study. Advanced International Federation of Gynecology and Obstetrics stages (stage III and IV) and pure type small cell neuroendocrine carcinoma cases had a significantly worse prognosis. Upon multivariate analysis, only histologic subtypes and surgery were significant prognostic factors. Pure type cases had a significantly worse prognosis compared to mixed type cases and complete surgery cases had a significantly better prognosis compared to cases with no or incomplete surgery. CONCLUSION: Our findings suggest that complete surgery improves the prognosis of neuroendocrine carcinoma of the endometrium. Even among cases with advanced disease stages, if complete surgery is expected to be achieved, clinicians should consider curative surgery to improve the prognosis of neuroendocrine carcinoma of the endometrium.
