PURPOSE: The purpose of this study was to elucidate prognostic factors for survival and clinical outcomes of rological soft tissue sarcomas (STSs). MATERIALS AND METHODS: This was a retrospective review of the medical records of 48 patients with urological STS treated from January 1982 to July 2009. Demographic and pathological characteristics were compared. Patients' demographics, clinico-pathological parameters, overall survival, and the factors expected to predict survival, such as sex, age at diagnosis, primary organ, surgical resection, metastasis, and mass size, were analyzed. We evaluated differences in survival on the basis of histological subtype by Kaplan-Meier analysis and multivariate Cox proportional hazards regression. RESULTS: The study included 34 males (70.8%) and 14 females (29.1%). The mean age at diagnosis was 47.1 years (range, 3 to 80). The most common site was the retroperitoneum (n=16), followed by the kidney (n=12), prostate (n=10), bladder (n=7), ureter (n=1), and paratesticular region (n=1). Nineteen patients (39.5%) had other organ metastases at diagnosis. The most common subtypes of sarcoma were leiomyosarcoma (50%), rhabdomyosarcoma (18.7%), and liposarcoma (8%). The remaining 11 cases had other histological subtypes (22.9%). Mean tumor size was 9.5 cm (range, 2.2 to 24). Thirty-three patients (68.7%) underwent surgical resection. The overall survival rate at 5 years was 51.4%. In the univariate and multivariate analysis, surgical resection, primary tumor site, and metastasis at diagnosis remained significant predictors of prognosis. Patients with retroperitoneal sarcoma had a higher overall survival rate by 5 years compared with patients with other organ sarcoma. CONCLUSIONS: The overall survival rate at 5 years was 51.4%. Surgical resection, primary tumor site, and metastasis at diagnosis remained significant predictors of prognosis.

BACKGROUND: Efforts to overcome poor outcomes in patients with adult acute lymphoblastic leukemia (ALL) have focused on combining new therapeutic agents targeting immunophenotypic markers (IPMs) with classical cytotoxic agents; therefore, it is important to evaluate the clinical significance of IPMs. METHODS: Baseline characteristics and clinical outcomes of patients with adult ALL were retrospectively analyzed. The percentage of blasts expressing IPMs at diagnosis was measured by multicolor flow cytometry analysis. Samples in which > or =20% of blasts expressed an IPM were considered positive. RESULTS: Among the total patient population (N=230), almost all (92%) were in first or second hematological complete remission (HCR) and 54% received allogeneic hematopoietic cell transplant (allo-HCT). Five-year hematologic relapse-free survival (HRFS) and overall survival (OS) rates were 36% and 39%, respectively, and 45.6% and 80.5% of patients were positive for the IPMs CD20 and terminal deoxynucleotidyl transferase (TdT), respectively. Expression of CD20, CD13, CD34, and TdT was associated with HRFS rate, and expression of CD20 and CD13 was associated with OS rate, as was the performance of allo-HCT. In multivariate analysis, positivity for CD20 (HRFS: hazard ratio [HR], 2.21, P<0.001; OS: HR, 1.63, P=0.015) and negativity for TdT (HRFS: HR, 2.30, P=0.001) were both significantly associated with outcomes. When patients were categorized into three subgroups according to positivity for CD20 and TdT, there were significant differences in HRFS and OS among the subgroups. CONCLUSION: Positivity for CD20 and TdT expression and clinical risk group were prognostic factors in adult ALL.

BACKGROUND AND PURPOSE: Decreasing the time delay for thrombolysis, including intravenous thrombolysis (IVT) with tissue plasminogen activator and intra-arterial thrombectomy (IAT), is critical for decreasing the morbidity and mortality of patients experiencing acute stroke. We aimed to decrease the in-hospital delay for both IVT and IAT through a multidisciplinary approach that is feasible 24 h/day. METHODS: We implemented the Stroke Alert Team (SAT) on May 2, 2016, which introduced hospital-initiated ambulance prenotification and reorganized in-hospital processes. We compared the patient characteristics, time for each step of the evaluation and thrombolysis, thrombolysis rate, and post-thrombolysis intracranial hemorrhage from January 2014 to August 2016. RESULTS: A total of 245 patients received thrombolysis (198 before SAT; 47 after SAT). The median door-to-CT, door-to-MRI, and door-to-laboratory times decreased to 13 min, 37.5 min, and 8 min, respectively, after SAT implementation (P<0.001). The median door-to-IVT time decreased from 46 min (interquartile range [IQR] 36–57 min) to 20.5 min (IQR 15.8–32.5 min; P<0.001). The median door-to-IAT time decreased from 156 min (IQR 124.5–212.5 min) to 86.5 min (IQR 67.5–102.3 min; P<0.001). The thrombolysis rate increased from 9.8% (198/2,012) to 15.8% (47/297; P=0.002), and the post-thrombolysis radiological intracranial hemorrhage rate decreased from 12.6% (25/198) to 2.1% (1/47; P=0.035). CONCLUSIONS: SAT significantly decreased the in-hospital delay for thrombolysis, increased thrombolysis rate, and decreased post-thrombolysis intracranial hemorrhage. Time benefits of SAT were observed for both IVT and IAT and during office hours and after-hours.
