PURPOSE: This randomized study compared the results achieved by concurrent chemoradiotherapy (CRT) versus radiotherapy (RT) alone for nasopharyngeal carcinoma (NPC) with advanced nodal disease. PATIENTS AND METHODS: Patients with nonkeratinizing/undifferentiated NPC staged T1-4N2-3M0 were randomized to CRT or RT. Both arms were treated with the same RT technique and dose fractionation. The CRT patients were given cisplatin 100 mg/m2 on days 1, 22, and 43, followed by cisplatin 80 mg/m2 and fluorouracil 1,000 mg/m2/d for 96 hours starting on days 71, 99, and 127. RESULTS: From 1999 to January 2004, 348 eligible patients were randomly assigned; the median follow-up was 2.3 years. The two arms were well-balanced in all prognostic factors and RT parameters. The CRT arm achieved significantly higher failure-free survival (72% v 62% at 3-year, P = .027), mostly as a result of an improvement in locoregional control (92% v 82%, P = .005). However, distant control did not improve significantly (76% v 73%, P = .47), and the overall survival rates were almost identical (78% v 78%, P = .97). In addition, the CRT arm had significantly more acute toxicities (84% v 53%, P < .001) and late toxicities (28% v 13% at 3-year, P = .024). CONCLUSION: Preliminary results confirmed that CRT could significantly improve tumor control, particularly at locoregional sites. However, there was significant increase in the risk of toxicities and no early gain in overall survival. Longer follow-up is needed to confirm the ultimate therapeutic ratio. 相似文献

Objective. Depression after stroke (DAS) poses a treble burden to patients, families and health care system. The purpose of this paper is to estimate the incidence of depression among first-ever ischemic stroke patients and identify the predictors of DAS. Methods. A longitudinal study design was undertaken. Of 836 patients admitted to the stroke unit of two regional hospitals in Hong Kong during the period 1 June 2004 to 31 May 2005, 295 patients fulfilled the inclusion and exclusion criteria. A total of 260 patients had given their consents and were interviewed at 1 month after stroke onset. Results. Nearly one-quarter of the first ischemic stroke patients, who were known to be free of personal and family history of psychiatric illnesses, were found to satisfy the criteria of depression using Diagnostic and Statistical Manual IV (24%, 48 out of 200 participants; 95% CI: 18.6%, 30.4%). This result was close to that assessed by the Geriatric Depression Scale (GDS) – 15 items. The psycho-emotional factor and level of dependency were found to be most significant predictors for DAS onset. Conclusion. The high incidence of DAS and low rate of accessibility to treatment indicate timely action to be undertaken. 相似文献

Cerebellar hemorrhage is the least common type of intracranial hemorrhage (ICH) encountered in clinical practice, and clinical data concerning the long-term outcomes are limited. This study aimed to investigate the long-term outcomes following spontaneous cerebellar hemorrhage in a cohort of Chinese patients. This single-center observational study was carried out between 1996 and 2010 and included 72 consecutive Chinese patients with a first spontaneous cerebellar hemorrhage. Of 440 patients with primary ICH, 72 (16.4%) had primary cerebellar hemorrhage. The mean age was 67.5?±?12.3?years and patients were predominantly male (54%). The 30-day mortality was 16.7% with Glasgow coma scale ??8 as the only predictor. At 6?months, 56.7% of patients who survived the first 30?days had a persistently poor functional status with modified Rankin scale score >2. After a mean follow-up of 4.7?years, 3.3% of patients had recurrent ICH, a recurrence rate of 7.3 per 1,000 patient-years. Ischemic stroke occurred in 12% of patients, an incidence of 25.5 per 1,000 patient-years. This study provided data on the long-term outcome of post-cerebellar hemorrhage in Chinese patients. 相似文献

The present study reviewed the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) baseline test scores of 247 high school athletes ages 13 to 18 from a private school in Hawai‘i. The aim of the research was to update a prior exploratory investigation conducted in 2008 that compared the test scores of Hawai‘i public high school athletes with the normative data provided by the ImPACT publishers. The results of this study provide assurance that the present ImPACT scores of the Hawai‘i high school athletes are similar to the general ImPACT norms. The present study is a rare effort to compare the ImPACT scores of high school athletes from an ethnically diverse region with the ImPACT norms. The findings offer further support for the use of the ImPACT norms when evaluating high school athletes from Hawai‘i. Future research in various regions of the United States and with other sociocultural backgrounds is encouraged. 相似文献

ObjectivesThe aim of the present study is to evaluate the feasibility and safety of performing PNL under local anesthesia in a selected group of patients who are at high risk for general anesthesia.Patients and methodsForty seven patients underwent PNL under local anesthesia. There were 38 males and 9 females with a mean age of 62 years. All patients were at medical high-risk for general anesthesia, with an American Society of Anesthesiologists (ASA) score of 3. The indications for local anesthesia in this study were obstructed single functioning kidney with azotemia in 29 patients, hepatic insufficiency in 8 patients, cardiac problems in 7 patients and 3 patients had hepatocellular carcinoma. The mean stone size was 2.7 cm (range 2–3.1 cm). Local infiltration with 10–20 cc of 2% lidocaine at the site of puncture was used in all cases. Narcotics were given 30 min prior to the procedure and medazolam was given intraoperatively upon demand. Utrasound guided puncture was performed in all cases and tract dilatation was then done under fluoroscopy using high pressure balloon catheter in 35 and Alken's metal dilators in 12 cases. Stones were then retrieved after disintegration in the same cession in 33 patients, while the other 14 patients underwent staged PNL, where a 12 Fr. nephrostomy tube was placed in the first stage, followed by tract dilatation and stone retrieval one week later.ResultsOut of 47 patients included, 44 had successful PNL either one stage (30 patients) or two stages (14 patients). Only 3 patients could not tolerate pain and the procedure was terminated after placement of nephrostomy tube and stone retrieval was completed later under general anesthesia.ConclusionOur results demonstrated that PNL under local anesthesia with narcotics and sedatives seems to be a satisfying solution for the treatment of a selected group of patients with renal pelvic stones and who have high anesthetic risk. However, additional studies with different groups of patients are required to validate our results. 相似文献
