BACKGROUND: Hybrid endoscopic submucosal dissection (ESD) has been described as an alternative to traditional ESD. This technique is less time consuming, but the en bloc resection rate is lower than in ESD. Similar to endoscopic mucosal resection, the underwater technique could improve preliminary disadvantages of hybrid ESD. CASE REPORT: We attempted a mixture resection technique of Hybrid ESD with underwater endoscopic mucosal resection (EMR). Using this approach, an underwater hybrid ESD was successfully performed without adverse events on a 71 year old woman with a 20 mm adenoma...

BACKGROUND & AIMS: Survival times vary among patients with neuroendocrine tumors (NETs)-even among those with the same site, stage, and grade of primary tumor. This makes it difficult to select treatment for patients with unresectable NETs, because some patients can survive decades without treatment. (68)Gallium-DOTATATE positron emission tomography with computed tomography ((68)Ga-DOTATATE PET/CT) is a sensitive imaging technique for detection of NETs. We investigated the prognostic accuracy of (68)Ga-DOTATATE PET/CT analysis of tumor volume in patients with NETs...

The novel drug delivery system based on self-assembly of zinc phthalocyanine-soybean phosphatidylcholine (ZnPc-SPC) complex was developed by a co-solvent method followed by a nanoprecipitaion technique. DSPE-PEG-methotrexate (DSPE-PEG-MTX) was introduced on the surface of ZnPc-SPC self-assembled nanoparticles (ZS) to endow them with folate receptor-targeting property. NMR, XRD, FTIR, and UV-vis-NIR analysis demonstrated the weak molecular interaction between ZnPc and SPC. The ZS functionalized with DSPE-PEG-MTX (ZSPM) was successfully constructed with an average particle size of ∼170nm, a narrow size distribution, and could remain physiologically stable for at least 7days...

BACKGROUND: Many solid neoplasms have a propensity for osteomedullary metastases of which detection is important for staging and subsequent treatment. Whole-body magnetic resonance imaging (WB-MRI) has been shown to accurately detect osteomedullary metastases in adults, but these findings cannot be unconditionally extrapolated to staging of children with malignant solid tumors. OBJECTIVE: To conduct a literature review on the sensitivity of WB-MRI for detecting skeletal metastases in children with solid tumors...

PURPOSE: Temozolomide (TEM) based therapy has been reported being effective in the treatment of metastatic neuroendocrine neoplasms (NEN), with response rates ranging from 30 to 70%. Among patients affected by advanced glioblastoma or melanoma and treated with TEM, loss of tumoral O6-methylguanine DNA methyltransferase (MGMT) is correlated with improved survival. In NEN patients, the role of MGMT deficiency in predicting clinical outcomes of TEM treatment is still under debate. METHODS: In this study we evaluated 95 patients with advanced NENs undergoing treatment with TEM-based therapy...

The oncogenic capacity of cyclin D1 has long been established in breast cancer. CCND1 amplification has been identified in a subset of patients with poor prognosis, but there are conflicting data regarding the predictive value of cyclin D1 protein overexpression. This study was designed to analyze the expression of cyclin D1 and its correlation with CCND1 amplification and their prognostic implications in invasive breast cancer. By using the tissue microarray technique, we performed an immunohistochemical study of ER, PR, HER2, p53, cyclin D1, Ki67 and p16 in 179 invasive breast carcinoma cases...

The objective was to determine the 10-year oncological safety of nipple-sparing mastectomy (NSM) in patients diagnosed with ductal carcinoma in situ (DCIS). The use of NSM preserves the nipple-areola complex (NAC). As residual fibroglandular breast tissue can remain behind the spared NAC, its use for patient with breast cancer is controversial. The oncologic outcomes and complication rates after performing NSM compared to other techniques are still under debate and a concern when treating patients with breast cancer...

BACKGROUND: Currently, the treatment of large hepatocellular carcinoma (HCC) is still a challenging problem. Transcatheter arterial chemoembolization (TACE) is the main treatment for intermediate end-stage HCC, while it is only a palliative and not a curative treatment due to the existence of residual tumors, and radiofrequency ablation (RFA) has limitations in complete ablation of large HCC. We hypothesized that TACE combined with simultaneous RFA (herein referred to as TACE + RFA) could improve the efficacy and survival of large HCC...

BACKGROUND: Total removal of craniopharyngiomas is burdened by high morbidity. In cases of a cystic or mixed craniopharyngioma, when the symptoms are caused by the cystic component of the tumor, a less invasive surgical approach aiming at cyst drainage may be recommended. Here we report our experience with intraventricular neuroendoscopy, describing our clear-cut surgical technique, and analyzing results in the context of literature data. METHODS: We reviewed the clinical data of 8 consecutive adult patients affected by cystic or mixed craniopharyngioma that were treated with intraventricular neuroendoscopy at our Institution in the last decade...
