The majority of EOC patients present with an advanced International Fed-eration of Gynecology and Obstetrics stage disease. The current standard treatment for these patients con-sists of complete cytoreduction and combined systemic chemotherapy of a platinum agent and paclitaxel. Even if the majority of patients with EOC respond to frst-line platinum based chemotherapy, almost 20% of them are resistant or refractory. According to these data, the main risk is for a certain number of patients to have undergone cytoreductive surgery （CRS） and subsequent hyperthermic intraoperative peritoneal chemotherapy （HIPEC） in a useful way. Radical surgery, especially in advanced cases, is associated with a high incidence of postoperative morbidity and mortality, which could be increased by the HIPEC. Every effort should be made for previously selected patients to improve outcome and optimize resources. Over the last decade, new options have been introduced to prolong survival. Im-proved long-term results can be achieved using CRS in combination with intraoperative HIPEC. This combina-tion has also been used in an up-front setting. Contro-versial outcomes have been reported for neoadjuvant platinum-based chemotherapy. Different papers have been published reporting discordant results. Further studies are needed.展开更多
在n-Rayleigh信道下,研究了MRC(Maximal Ratio Combining)合并接收系统的平均码字错误率(ASEP)性能。基于矩生成函数(MGF)的方法,推导了MRC接收系统在n-Rayleigh衰落信道上采用M进制相移键控(MPSK),M进制正交幅度调制(MQAM)和M进制脉冲...在n-Rayleigh信道下,研究了MRC(Maximal Ratio Combining)合并接收系统的平均码字错误率(ASEP)性能。基于矩生成函数(MGF)的方法,推导了MRC接收系统在n-Rayleigh衰落信道上采用M进制相移键控(MPSK),M进制正交幅度调制(MQAM)和M进制脉冲幅度调制(MPAM)等几种M进制数字调制方式的ASEP的计算式。然后在不同条件下,仿真了系统的ASEP性能,仿真值与理论值相一致,理论分析的正确性得到了证明。分析结果表明:分集支路数和衰弱因子对系统的ASEP性能有重要影响。展开更多
