Combined androgen blockade in the management of advanced prostate cancer: A sensible or ostensible approach

BACKGROUND: To compare the efficacy of orchiectomy alone and orchiectomy plus flutamide in treating patients with advanced carcinoma prostate. MATERIALS AND METHODS: The study was initiated on 1 July 1997 and closed after enrolling 100 patients on 30 June 2000. Patients were prospectively randomized to orchiectomy alone (O) and orchiectomy plus flutamide (OF). A complete response (CR) was defined as the normalization of bone scans and serum prostate-specific antigen (PSA) levels returning to normal (< 4 ng/mL). A partial response (PR) was defined as a 50% reduction in metastasis mass compared to the initial study or a decrease in the PSA level of 50% of the initial value. Progressive disease (PD) was defined as the development of any new hot spot on bone scan or any increase in previously existing PSA level by 25%. RESULTS: A total of 100 patients were entered in the study. The maximum percentage change in PSA levels in both groups was found in the first 3 months after orchiectomy, that is, 95% and 97% for the O and OF groups, respectively. In more than 80% of the patients this decrease in PSA was maintained for 3 years. The mean percentage change at 3 years in the O and OF groups was 70% and 75% (P = 0.95), respectively, and the overall response rate (CR + PR) was 88.50% and 86.53% in the two groups, respectively (P = 0.85). The follow-up period ranged between 3 and 5 years (mean, 3.5 years). The mean time to progression was 27 and 29 months in the O and OF groups, respectively. The overall survival rate at 3 and 5 years in two treatment groups was 45.83% and 48.07%, 20.83% and 23.07% in the O and OF groups, respectively (P = 0.75). CONCLUSIONS: Maximum percentage decrease in PSA is seen within the first 3 months of therapy. Orchiectomy alone is as effective as combination therapy in decreasing serum PSA. Overall survival at 3 and 5 years in the orchiectomy only group was as good as that of combination therapy. These data suggest that the routine addition of flutamide to orchiectomy is not advisable.     

健脾疏肝利水法为主内外合治恶性腹腔积液

观察健脾疏肝利水为主的中医药内服外敷治疗恶性腹腔积液的疗效。设治疗组 3 8例采用内服中药加中药外敷腹部 ,配服西药利尿剂。对照组 2 7例 ,常规服西药利尿剂及对症治疗 ,疗程均为 1个月。结果 :治疗组有效率为65 7% ,对照组有效率为 48 1% (P <0 0 5 )。生存期 6个月以上、1年以上者 :治疗组分别为 12例、4例 ,对照组为 5例、0例。提示以中医药内外合治为主对恶性腹腔积液疗效明显高于单纯用西药利尿剂     

颈椎椎体次全切除钛网钉板系统的临床应用

目的探讨颈椎前路椎体次全切除钛网钉板植骨融合的临床效果。方法自2001年3月～2003年3月间应用颈前路椎体次全切除钛网植骨融合及钉板固定治疗颈椎管狭窄性疾病22例，其中4例患者行2椎体次全切除3节椎间隙减压手术。术后观察减压、固定、融合及神经功能恢复情况，并行X线摄片或CT扫描检查。结果患者获6～12个月随访，神经功能得到不同程度改善，无加重情况。椎间隙高度无丢失、无成角，均获得骨性融合。术后3d在颈围领固定下下床活动，4周后可恢复较轻工作。结论此术式可避免传统手术方法的缺点，即不取自体髂骨，融合率高，稳定性好，并减压彻底，疗效好，是一种值得推广的新技术。     

应用联合减压术治疗中晚期脑疝疗效观察
