Efficacy of preoperative intracavitary brachytherapy and surgery in patients with stage ⅠB2 and ⅡA bulky cervical cancer

Objective To analyze the outcomes of preoperative intracavitary brachytherapy plus sur-gery in patients with stage ⅠB2 and ⅡA bulky cervical cancer. Methods From January 2001 to January 2007, 77 patients with stage ⅠB2 and ⅡA bulky cervical cancer were included. The diameter of primary tumor was greater than 4 cm. Preoperative intracavitary brachytherapy with the total dose of 20-30 Gy (0.5 cm below the vaginal mucosa) was delivered by 2-3 fractions, one fraction per week. After an interval of 10-14 days, the efficacies of radiotherapy were evaluated and radical hysterectomy with pelvic lymphade-nectomy was performed. Then the treatment complications, clinicopathological characteristics, survival and recurrence were analyzed. Results The tumor shrinkage was observed in all the patients after intracavitary brachytherapy. The CR, PR and SD were 5% (4/77), 36% (28/77) and 58% (45/77), respectively. Radical hysterectomy was successfully performed in all patients. The complications of the combined therapy were mild and only 5 patients had grade Ⅱ or less hematological or gastrointestinal toxicities. The 5-year o-verall survival rate and pelvic recurrence rate were 83% and 12%, respectively. Conclusions Preoperative intracavitary brachytherapy of 20-30 Gy plus surgery is effective in the treatment of stage ⅠB2 and ⅡA bulky cervical cancer without increasing the treatment complications.

血清ＣＡ１２５在卵巢上皮性癌中的应用研究进展

卵巢恶性肿瘤是女性常见的恶性肿瘤，发病率在女性生殖道肿瘤中位于第３位，但死亡率却位居女性生殖道肿瘤之首。由于早期症状隐匿，接近２／３的患者诊断时已为Ⅲ期或Ⅳ期，５年生存率明显低于Ⅰ期或Ⅱ期。由于早期卵巢癌的预后要明显好于晚期卵巢癌，卵巢癌的早期诊断已成为提高患者生存率的一项重要的因素。血清癌抗原１２５（ＣＡ１２５）ＥＬＩＳＡ检查已常规用于卵巢癌的诊断和病情监测，本文拟就ＣＡ１２５目前在卵巢癌临床工作中的应用及近年相关新的研究进展作一综述。
