Clinical Analysis of 57 Patients with Ovarian Dysgerminoma

Objective  Ovarian dysgerminoma is an uncommon ovarian malignancy, Its clinicai features are special and there are many factors affecting its prognosis. If treated properly, the patient can be cured. Otherwise it may endanger the patient’s life. The aim of this study is to investigate the clinical features and factors related to prognosis of ovarian dysgerminoma. Methods  Data from 57 patients with pure ovarian dysgerminoma were analyzed retrospectively. The patients were admitted to the Cancer Center, Sun Yat-sen University from January 1.1964 to December 31, 2000. Results  The main clinical features were abdominal mass (56.1% ), abdominal pain (21.1% ), abdominal swelling (17.5%.), vaginal bleeding (5.3% )and genital tract abnormalities (5.3%). Twenty-six patients had stage I diseases, 8 stage II.9 stage III.1 stage IV and 13 recurrent and persistent diseases. The uterus was involved in 41.2% of patients with stage II -III diseases. Combined modality was given to 52 cases and a single-method treatment to 5 cases. The total overall 5 and 10-year survival rates for stages I-IV was 80.1 % and 70.0% respectively. The 5-year survival rate for stage I was 100%, stage II 55.2%. stage III 55.6% and stage IV 0%; for recurrent and persistent diseases, 72.7%. The stage I group of 12 patients. received adnexectomy and 14 patients underwent hysterectomy and adnexa removal. There was no significant difference between the 5 and 10-year survival rates (all 100%). Of the 23 patients in the stage I group to whom oniy chemotherapy was given after operation, 19 cases received 3 or more courses and were well without recurrence; 4 patients received only one course and one of them recurred 21 months after the operation. In the group of stages II and III cases, the 5-year survival rate was 86.7% for those whose chemotherapy courses were 3≥ 4 and 25.0% for patients who received less than 4 courses of chemotherapy (P<0.05). Conclusions  The prognosis of ovarian dysgerminoma is closely related to the disease stage and treatment modality. A fertility-preserving operation can be considered in early -staged patients, but caution needs to be exercised in the middle to late staged cases. Good results can be achieved with an operation-based combined modality in recurrent patients.     

龙参颗粒的质量标准研究

目的:为龙参颗粒提供方便可行的质量控制方法。方法:采用薄层色谱法进行定性鉴别;用HPLC法对成品中苦参碱进行含量测定。结果:薄层层析可成功鉴别出当归和黄芪药材;Hypersil NH_2,色谱柱(4.6mm×200mm,5μm);柱温:25℃;流动相:乙腈-0.02mol/L磷酸二氢钠(82:18);流速:1mL/min;检测波长:215nm。加样回样率为97.70％,RSD为1.56％。结论:本实验方法基本可控制龙参颗粒的质量。     

胆囊腺瘤-腺癌中的DNA含量和基因表达

目的 研究胆囊腺瘤从增殖到恶变中腺上皮细胞的增殖变化和基因表达。方法PCR-RFLP法测定APC、ras基因突变,ABC免疫化学组织染色法测定p53蛋白表达。用TJTY-300全自动图像分析仪测定胆囊上皮细胞核异型性和DNA含量。结果 上皮细胞核异型性和DNA含量在胆囊腺瘤-腺癌过程中逐渐增加。胆囊腺瘤中异倍体比例与腺瘤的大小有明显的关系,直径≥1cm异倍体显著增加(P<0.05)。在胆囊腺瘤-腺癌过程中可检测到APC基因和RAS基因突变。P53蛋白在这一过程中不表达。结论 胆囊腺瘤-腺癌的过程是胆囊癌发生中一条重要的途径。当胆囊腺瘤直径≥1cm时具有明显的癌变潜能。其分子改变机制与胆囊上皮不典型增生-原位癌途径不同。
