We newly diagnosed 131 patients with extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue lymphoma between 1998 and 2010. We retrospectively studied 124 patients for whom complete clinical data were available at presentation and who had minimally undergone tumour staging by physical examination, computed tomography (CT), bone marrow aspiration, and biopsy. A slight female predominance (men, 58; women, 66) was observed in the study population; the median age was 67years. The primary locations at presentation were the stomach (38%), orbita (20%), lung (12%), intestinal tract (8%), thyroid gland (6%), others (14%), and unknown (2%). Seventy per cent of patients had localized disease. Of the 124 patients, 14 (11%) had lymph node involvement, and 5 (4%) had bone marrow involvement. Five (4%) patients had both lung and gastric involvement. The 5-year overall survival rate for the 124 patients was 96.1%. The overall vital prognosis was excellent. Moreover, gastro-intestinal fiberscopic examination is essential, especially in cases with lung involvement at presentation. © 2012 John Wiley & Sons, Ltd.

The Sokal and Hasford scores were developed in the chemotherapy and interferon era and are widely used as prognostic indicators in patients with chronic myeloid leukemia (CML). Recently, a new European Treatment and Outcome Study (EUTOS) scoring system was developed. We performed a multicenter retrospective study to validate the effectiveness of each of the three scoring systems. The study cohort included 145 patients diagnosed with CML in chronic phase who were treated with imatinib. In the EUTOS low- and high-risk groups, the cumulative incidence of complete cytogenetic response (CCyR) at 18 months was 86.9% and 87.5% (P = 0.797) and the 5-year overall survival rate was 92.6% and 93.3% (P = 0.871), respectively. The cumulative incidence of CCyR at 12 months, 5-year event-free survival and 5-year progression-free survival were not predicted using the EUTOS scoring system. However, there were significant differences in both the Sokal score and Hasford score risk groups. In our retrospective validation study, the EUTOS score did not predict the prognosis of patients with CML in chronic phase treated with imatinib. © 2013 The Authors.

Background: Malignant lymphoma with central nervous system (CNS) involvement has an extremely poor prognosis. We retrospectively studied the risk factors for CNS involvement in patients with diffuse large B-cell lymphoma (DLBCL) treated by cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) or rituximab (R) -CHOP chemotherapy. Patients and methods: We studied 375 consecutive patients who were newly diagnosed with DLBCL between 1996 and 2006. Patients with primary CNS involvement and patients who received CNS prophylaxis were excluded. All the patients received CHOP (n = 172) or R-CHOP (n = 203) chemotherapy. The following variables were assessed for their potential to predict CNS involvement: gender, age, serum lactate dehydrogenase (LDH) level, performance status, clinical stage, number of extranodal involvements, International Prognostic Index (IPI), bone marrow involvement, presence of a bulky mass, presence of B symptom, and treatment. Results: CNS involvement was observed in 13 cases (3.5%). In univariate analysis, LDH more than normal range, LDH more than twice as normal range, high IPI, bone marrow involvement, and systemic relapse were the predictors for CNS involvement. In multivariate analysis, no risk factors were detected for CNS involvement. The use of rituximab did not have an impact on CNS involvement. Conclusions: The incidence of CNS involvement dose not decrease in rituximab-era. © 2010 John Wiley & Sons A/S.

Eye (Basingstoke) | Year: 2012
PurposeTo assess the additive effect of diquafosol tetrasodium on sodium hyaluronate monotherapy in patients with dry eye syndrome.MethodsThis study evaluated 64 eyes of 32 patients (age: 62.6±12.8 years (mean±SD)) in whom treatment with 0.1% sodium hyaluronate was insufficiently responsive. The eyes were randomly assigned to one of the two regimens in each patient: topical administration of sodium hyaluronate and diquafosol tetrasodium in one eye, and that of sodium hyaluronate in the other. Before treatment, and 2 and 4 weeks after treatment, we determined tear volume, tear film break-up time (BUT), fluorescein and rose bengal vital staining scores, subjective symptoms, and adverse events.ResultsWe found a significant improvement in BUT (P0.049, Dunnett test), fluorescein and rose bengal staining scores (P0.02), and in subjective symptoms (P0.004 for dry eye sensation, P0.02 for pain, and P0.02 for foreign body sensation) 4 weeks after treatment in the diquafosol eyes. On the other hand, we found no significant change in these parameters after treatment in the control eyes.ConclusionsIn dry eyes, where sodium hyaluronate monotherapy was insufficient, diquafosol tetrasodium was effective in improving objective and subjective symptoms, suggesting its viability as an option for the additive treatment of such eyes. © 2012 Macmillan Publishers Limited All rights reserved.

Objectives: Paralyzed tissue due to long-term denervation is resistant to many treatments because it induces irreversible histological changes and disorders of deglutition or phonation. We sought to determine the effect of autologous transplantation of fascia into the vocal fold (ATFV) with controlled release of basic fibroblast growth factor (bFGF) on long-term unilateral vocal fold paralysis (UVFP). Methods: Unilateral recurrent laryngeal nerve (RLN) section was performed on 20 rats. Five rats were implanted with autologous fascia only (fascia group), and 10 rats were implanted with autologous fascia and a gelatin hydrogel sheet with 1 μg (1 μg bFGF + fascia group) or 0.1 μg (0.1 μg bFGF + fascia group) of bFGF 4 months after RLN section. We evaluated the normalized glottal gap and laryngeal volume and histological changes 3 months after implantation. Results: The normalized glottal gap was significantly reduced in the 3 fascia implantation groups. Normalized laryngeal volume, fat volume, and lateral thyroarytenoid muscle volume were significantly increased in the 2 fascia implantation with bFGF groups. Conclusions: The ATFV with controlled release of bFGF repaired the glottal gap and laryngeal volume after RLN section and may reduce the occurrence of aspiration and hoarseness. We speculate that this treatment improves laryngeal function in long-term RLN denervation. © SAGE Publications.
