卵巢未成熟畸胎瘤43例综合治疗疗效分析

为探讨不同手术方式及化疗方法对卵巢未成熟畸胎瘤的疗效及相关影响因素，对43例卵巢未成熟畸胎瘤患者进行回顾性分析。手术方式分为：保守性手术（患侧附件、大网膜切除术＋盆、腹腔腹膜结节切除术＋盆腔淋巴结清扫术）及根治性手术（全子宫、双附件及大网膜切除术＿肿瘤细胞减灭术＋盆腔淋巴结清扫术）。术后采用VAC（长春新碱，阿霉素，环磷酰胺）方案、BEP（博莱霉素或平阳霉素，足叶乙叉甙，顺铂或卡铂）方案或VBP（长春新碱，博莱霉素或平阳霉素，顺铂或卡铂）方案进行联合化疗。患者5年生存率根治性手术为44．4％，保守性手术为64．0％，差异无显著性。VAC方案与BEP（或VBP）方案的5年生存率分别为33．3％和77．3％（P＜0．01）。疗程数≥4患者的5年生存率为73．9％，明显高于疗程数＜4患者的38．9％（P＜0．05）。认为对于有生育要求的卵巢未成熟畸胎瘤患者，可仅行保守性手术，术后辅以联合化疗。BEP（或VBP）方案对患者长期生存率的改善明显优于VAC方案。术后化疗的疗程数与疗效有关，对长期生存率的影响较明显。

Primary tubal choriocarcinoma

Choriocarcinoma is one of the most serious forms of gestational trophoblastic tumor. It is a malignant tumor from the epithelium of the chorionic villi. The most frequent location site is the uterus. Associated with ectopic pregnancy, it is extremely rare and in general, very aggressive. In 75% of the cases, it items from distant metastasis; therefore, a histological examination of the tubes must be performed in all ectopic pregnancies. Our patient was a 33-year-old woman who was admitted to emergency room (ER) with an intense pain in the right, iliac cavity, and limited genital bleeding. During the exploration, there was abdominal pain, with doubtful signs of peritoneal irritation. The vaginal ultrasound offered an image that was compatible with an extra uterine pregnancy in the left appendages. At emergency, right salpingectomy was performed via laparotomy. The patient was treated with polychemotherapy and contraceptives for a year, with no recurrence of the disease. Control follow-up was performed using beta-human chorionic gonadotropin (HCG) testing on a weekly basis during the first month and then bi-monthly during the first year of follow-up.     

Prognostic importance of the time interval from surgery to chemotherapy in treatment of ovarian carcinoma

In a large study on 1,220 patients with ovarian carcinoma in FIGO stages I-IV, the prognostic importance of the time factor for start of postoperative chemotherapy was studied together with other important factors for long-term survival. The patient series was a total geographic material of ovarian carcinoma patients treated during the years 1975-1993. All patients were followed up for 10 years or until death. The 5-year cancer-specific survival rate of the complete series was 50%. Significant and independent prognostic factors with regard to long-term cancer-specific survival were FIGO stage, histology, tumor grade, and completeness of the primary surgery. Special attention was paid to the prognostic importance of the time interval between primary surgery and the first course of chemotherapy. Patient groups with intervals shorter or longer than the median value were compared. In early-stage disease, no significant difference was noted. In advanced and bulky disease, an interval longer than the median value seemed to be beneficial compared with a shorter interval. However, after correction for other prognostic factors, the interval was not a significant factor (P = 0.647) with regard to the cancer-specific survival rate. Therefore, the time factor should not be an important argument for how to best organize the gynecologic oncology service.

Preoperative Chemotherapy for Colorectal Liver Metastases: Impact on Hepatic Histology and Postoperative Outcome

Some investigators have suggested that preoperative chemotherapy for hepatic colorectal metastases may cause hepatic injury and increase perioperative morbidity and mortality. The objective of the current study was to examine whether treatment with preoperative chemotherapy was associated with hepatic injury of the nontumorous liver and whether such injury, if present, was associated with increased morbidity or mortality after hepatic resection. Two-hundred and twelve eligible patients who underwent hepatic resection for colorectal liver metastases between January 1999 and December 2005 were identified. Data on demographics, clinicopathologic characteristics, and preoperative chemotherapy details were collected and analyzed. The majority of patients received preoperative chemotherapy (n = 153; 72.2%). Chemotherapy consisted of fluoropyrimidine-based regimens: 5-FU monotherapy, 31.6%; irinotecan, 25.9%; and oxaliplatin, 14.6%. Among those patients who received chemotherapy, the type of chemotherapy regimen predicted distinct patterns of liver injury. Oxaliplatin was associated with increased likelihood of grade 3 sinusoidal dilatation (p = 0.017). Steatosis >30% was associated with irinotecan (27.3%) compared with no chemotherapy, 5-FU monotherapy, and oxaliplatin (all p < 0.05). Irinotecan also was associated with steatohepatitis, as two of the three patients with steatohepatitis had received irinotecan preoperatively. Overall, the perioperative complication rate was similar between the no-chemotherapy group (30.5%) and the chemotherapy group (35.3%) (p = 0.79). Preoperative chemotherapy was also not associated with 60-day mortality. In patients with hepatic colorectal metastases, preoperative chemotherapy is associated with hepatic injury in about 20 to 30% of patients. Furthermore, the type of hepatic injury after preoperative chemotherapy was regimen-specific.

Investigation of the Effect of Neoadjuvant Chemotherapy on Stage Ⅱ Breast Cancer

OBJECTIVE To investigate the effect of neoadjuvant chemotherapy in treatment of Stage Ⅱ breast cancer. METHODS The data from 113 patients with breast cancer of the same pathologic type in Stage Ⅱ,during the period of 1995 to 2001,were analyzed retrospectively.Among the patients,47 were treated with neoadjuvant chemotherapy,and 66 received no adjuvant therapy before surgery（control group）.After the patients of the neoadjuvant chemotherapy group had received 2 courses of chemotherapy with the CMF regimen,the surgical procedure was conducted. RESULTS Complete remission（CR）was attained in 9 of the 47 cases receiving neoadjuvant chemotherapy and partial remission（PR）was reached for 22 cases.The rate of breast-conserving surgery was enhanced from 22.73%to 46.81%（P〈0.05）in the neoadjuvant treatment group. There was no difference in the 5-year overall survival（OS）and disease-free survival（DFS）rate between the two groups（P〉0.05）,but the 5-year OS and DFS of the cases with clinical tumor remission was higher compared to the control group（P〈0.05）. CONCLUSION Neoadjuvant chemotherapy can enhance the rate of breast conservation for Stage Ⅱ breast cancer and may improve the prognosis of the cases with clinical remission.
