BACKGROUND: The aim of this study is to present our experience in 62 patients suffering from hepatocellular carcinoma (HCC) treated with transcatheter arterial chemoembolization (TACE) in two years. METHODS: TACE was performed with injection of doxorubicin mixed with lipiodol before embolization with spongostan. This procedure was repeated for 3 cycles almost. Follow-up was performed by US and CT and by assessment of clinical status and biochemical tests. TACE results were assessed comparing size, local spread and TACE technique with patients' survival. The lesion was single in 51 while multiple in 11. In 6 patients the lesion was greater than 5 cm while in 56 less than 5 cm. RESULTS: Overall survival rates were 95.7% at 6 months, 78.3% at 1 year, 46% at 2 years, 40% at 3 years. The best responses were obtained with single lesions smaller than 5 cm and treated with at least 3 cycles of TACE. CONCLUSIONS: We can conclude that TACE is an efficacious therapeutic choice in the HCC patients who cannot undergo surgery. 相似文献

We report the treatment outcome for 30 relapsed/refractory Waldenström's macroglobulinemia (WM) patients following bendamustine-containing therapy. Treatment consisted of bendamustine (90 mg/m2 I.V. on days 1, 2) and rituximab (375 mg/m2 I.V. on either day 1 or 2) for 24 patients. Six rituximab-intolerant patients received bendamustine alone (n = 4) or with ofatumumab (1000 mg I.V. on day 1; n = 2). Each cycle was 4 weeks, and median number of treatment cycles was 5. At best response, median serum IgM declined from 3980 to 698 mg/dL (P < .0001), and hematocrit rose from 31.9% to 36.6% (P = .0002). Overall response rate was 83.3%, with 5 VGPR and 20 PR. The median estimated progression-free survival for all patients was 13.2 months. Overall therapy was well tolerated. Prolonged myelosuppression was more common in patients who received prior nucleoside analogues. Bendamustine is active and produces durable responses in previously treated WM, both as monotherapy and with CD20-directed monoclonal antibodies. 相似文献

Aims In view of available targeted therapies, we investigated the presence of c-kit, PDGFR gene mutations and protein expression
in cancer of unknown primary (CUP) in order to study their contribution in pathogenesis, their prognostic value and potential
as therapeutic targets.
Methods Mutations in hot spots c-kit exon 11 and PDGFR exons 12 and 18 were studied in paraffin-embedded tumour samples from 50 patients
with CUP by means of PCR-based single-strand conformational polymorphism and protein expression by means of streptavidin-biotin
immunoperoxidase assays. Molecular markers were screened for possible correlations with patient outcome.
Results No shifted band was detected in any of the polyacrylamide gel electrophoreses, indicating absence of c-kit exon 11 and PDGFR
exon 12, 18 mutations. Immunohistochemical analysis in 37 tumours revealed positive membranous CD117 expression in 30 samples
(81%) of which five exhibited strong (+3), four moderate (+2) and 21 weak (+1) staining. PDGFRa protein staining was seen
in 15 out of 30 (50%) cases, mostly weak (13) and rarely moderate (1) or strong (1). The expression of KIT or PDGFRa protein
did not correlate with the clinical outcome of the patients in our cohort.
Conclusions In a moderate-sized CUP patient cohort, KIT or PDGFRa protein overexpression is rare, does not have gross prognostic significance
for survival and is not associated with presence of activating mutations. 相似文献

The application of digital panoramic radiography with photostimulable phosphors to dental diagnosis was evaluated in 500 patients. Comparative intraoral films of selected groups of teeth and electronic magnifications of the same portion of the arches were obtained in 63 cases. Digital images improved the quality of dental examinations compared with film radiographs. The possibility of contrast modulation was helpful to compensate for the different radiographic densities of the arches and to improve the visibility of gingival soft tissues. In addition, digital radiography reduced the radiation dose administered to the patient. The use of digital panoramic radiography is proposed as a substitute for film studies in all hospitals where a central unit for digital radiology is available.

Although the very high locoregional recurrence rates reported with limited D0/D1 surgery can be reduced with extended D2 gastrectomy for operable gastric cancer, overall relapse and survival rates remain poor and can only be improved with adequate perioperative adjuvant treatment. However, despite intensive research, no regimen has been established as standard. Meta-analyses have demonstrated a marginal survival benefit with adjuvant chemotherapy. Two recent large randomized trials for operable gastric cancer, the MAGIC trial and the INT-0116 trial, provide evidence that some patients may benefit from perioperative chemotherapy and chemoradiation, respectively. However, while both trials suggest an overall survival benefit with adjuvant treatment, they don't provide the harm-benefit ratio for specific subsets of patients wih different extent of surgery (D1 or D2) and tumor stage (early [T1,2]/advanced [T3,4]). This lack of evidence complicates current therapeutic adjuvant decisions. Estimating the risk of local and distant recurrence (high, moderate or low) after D1 or D2 surgery in various tumor stages and the expected harm-benefit ratio, the authors provide useful information for decisions on adjuvant chemotherapy with or withour radiotherapy in individual patients. Research on newer cytotoxic and targeted agents may improve treatment efficacy. Simultaneously, advances with microarray-based gene-expression profiling signatures may improve individualized treatment decisions. However, the validation and translation of these genomic classifiers as biomarkers into a completed 'bench-to-bedside' cycle for tailoring treatment to individuals is a major challenge and limits inflated expectations. 相似文献

Background: Diabetes is a significant challenge for pediatric health care professionals because it affects youths’ psychoemotional functioning and, consequently, the quality of life (QOL). The aim of the present study was to evaluate the QOL in young patients with diabetes, as well as the factors affecting it. Methods: The study was conducted from April to September 2008 in 98 young patients, 11–18 years of age, who were under the supervision of Diabetological Center, General Pediatric Hospital (Athens, Greece). The Diabetes Quality of Life for Youths Questionnaire was used to evaluate the QOL of youths with diabetes. Results: The mean QOL score was 97.5. There was a negative correlation between the QOL and age (P = 0.02), the duration of diabetes (P = 0.05), body mass index (BMI; P = 0.04), and comorbidities (P = 0.03). In contrast, there was a positive correlation between QOL and increased metabolic control (P = 0.03), participating in sports activities (P = 0.007), and a greater number of insulin infusions (P = 0.04). Conclusions: The QOL of young diabetics was influenced by demographic, somatometric, and other characteristics of diabetes. Increased metabolic control, participating in sports activities, and a greater number of insulin infusions resulted in better QOL. Increased patient age, duration of diabetes, HbA1c values, BMI, and the coexistence of various health problems, as well as the use of an insulin pump, decreased QOL. 相似文献

Summary: Thermophysical properties and molecular relaxations in aromatic amine‐cured diglycidyl ether of bisphenol‐A (DGEBA) epoxy oligomer and poly(ethylene oxide) (PEO) mixtures were determined by DSC and dielectric techniques (TSC, DRS). The binary blends were judged to be fully miscible in the amorphous state (wPEO < 40 wt.‐%), as evidenced by the single composition‐dependent glass transition temperatures Tgs. In the amorphous blends, negative deviations of dielectric/thermal Tg‐estimates from the linear mixing rule or the behavior predicted by the Fox equation reveal weaker intermolecular interactions, compared to strong self‐association of hydroxyls in the cured thermoset. Morphological changes in PEO‐rich blends (wPEO ≥ 40 wt.‐%) are in accordance with their complicated interface structure, previously reported to consist of amorphous PEO regions, branched epoxy resin chains and an imperfect epoxy resin network located between PEO lamellae. In these blends, PEO crystallites exert steric hindrances in the amorphous regions, causing strong Tg upshifts. Changes in the relaxation dynamics of glyceryl segments (e.g., in the activation energy barrier and relaxation strength) are in accordance with the idea that the close matching between the molecular polarities of PEO, epoxy resin and the cure agent significantly contributes to the observed miscibility.

We studied the role of histone deacetylase inhibitors in Waldenstrom's macroglobulinemia (WM). Gene expression profiling of bone marrow CD19+ cells from 30 patients and 10 healthy donors showed overexpression of HDAC4, HDAC9, and Sirt5, with validation of HDAC9 overexpression by q-PCR in primary and BCWM.1 cells. Suberoylanilide hydroxamic acid, trichostatin A, panobinostat, and sirtinol demonstrated dose-dependent killing of BCWM.1 cells. TSA showed the greatest potency with IC50 of 70 nM. Importantly, HDAC9 activity was decreased following TSA treatment suggesting an essential role for this HDAC in WM therapy. The combination of bortezomib plus HDAC inhibitors resulted in at least additive tumor cell killing in BCWM.1 cells. TSA and bortezomib-induced apoptosis depended on a similar set of caspase activation, whereas their effect on cell cycle regulators was distinctly different. These results provided a framework for examining HDAC inhibitors as monotherapy, as well as combination therapy with bortezomib in WM. 相似文献

Cancer of unknown primary represents a heterogeneous group of malignancies characterised by early systemic dissemination and
lack of primary site. KiSS1 is a member of the metastasis-suppressor gene family whose functional role is being investigated
in human malignancies. We extracted DNA from 50 paraffin-embedded unknown primary tumors and screened KiSS1 exons III and
IV for presence of mutations by means of Single Strand Conformational Polymorphism and direct sequencing. Only one tumor specimen
harboured a cytosine to guanine point substitution in base 242 of exon IVa, resulting in a proline to arginine switch at codon
81 of the KiSS1 protein (P81R). The remaining 49 tumors harbored wild-type KiSS1 alleles, indistinguishable from those of
peripheral blood lymphocytes of 50 healthy controls. Consequently, the propensity for systemic spread of unknown primary tumors
may by due to mutations in genes other than KiSS1 or aberrant epigenetic regulation. 相似文献
