PURPOSE The aim of this study was to evaluate the role of radiotherapy (RT) in the management of Ewing sarcoma family tumors (ESFT). MATERIALS AND METHODS Retrospective analysiswas performed on 91 patientswith localized ESFT treated from 1988 to 2012. Primary tumor size was ≥ 8 cm in 33 patients. Surgery, RT, and combined surgery with RT were applied in 37, 15, and 33 patients, respectively. ...

PURPOSE This study compared single-fraction to multi-fraction short-course radiation therapy (RT) for symptomatic metastatic epidural spinal cord compression (MESCC) in patients with limited survival prognosis. METHODS AND MATERIALS A total of 121 patients who received 8 Gy × 1 fraction were matched (1:1) to 121 patients treated with 4 Gy × 5 fractions for 10 factors including age, sex, perfo...

This retrospective study used a population-based national registry to determine the impact of local treatment modalities on survival in patients with metastatic esophageal cancer (EC). The Surveillance Epidemiology and End Results (SEER) database was used to identify patients with metastatic EC from 1988 to 2012. A total of 9,125 patients were identified. There were 426 patients underwent prima...

Koblitz curves have been a nice subject of consideration for both theoretical and practical interests. The window τ -adic algorithm of Solinas (window τNAF) is the most powerful method for computing point multiplication for Koblitz curves. Precomputation plays an important role in improving the performance of point multiplication. In this paper, the concept of optimal pre-computation for window...

PURPOSE To evaluate radiotherapy (RT) and chemotherapy (CT) treatments of early-stage extranodal natural killer/T-cell lymphoma (ENKTL). MATERIALS AND METHODS Fifty-five patients with stage I or II ENKTL [n=39 (71%) and 16 (29%) patients, respectively] who were treated with RT between 1999 and 2013 were analyzed retrospectively. The median age was 54 years (range, 24-81). Patients were groupe...

PURPOSE To compare accelerated hypofractionated (A-HYPO) radiotherapy (RT) with conventionally fractionated (CF) thoracic RT in patients with limited-disease small-cell lung cancer (LD-SCLC). METHODS Out of 217 consecutive LD-SCLC patients, treated between 1997 and 2012, 82 received CF-RT (44-60 Gy, 2 Gy/ fraction) sequentially to 4-6 cycles of platinum-based chemotherapy (CHT), and 100 recei...

The association of the results reverse transcription-PCR (RT-PCR) assays for prostate-specific antigen (PSA) with prostate cancer stage and progression remains controversial. We have previously shown that RT-PCR amplification of a native human glandular kallikrein fragment (hK2-L), but not a splice-variant hK2 transcript (hK2-U), performed preoperatively on peripheral blood before radical prost...

PURPOSE The European Organisation for Research and Treatment of Cancer and National Cancer Institute of Canada trial on temozolomide (TMZ) and radiotherapy (RT) in glioblastoma (GBM) has demonstrated that the combination of TMZ and RT conferred a significant and meaningful survival advantage compared with RT alone. We evaluated in this trial whether the recursive partitioning analysis (RPA) ret...

| The paper deals with the formal speciication of a general-purpose multimedia synchronization mechanism, known as the conditional delivery mechanism capable of addressing both intra-and inter-stream synchronization issues. The proposed mechanism, initially introduced in 3, 11], is based on the identiication of causal relations among information units of one or several streams and has the purpo...
