Histopathologic parameters of prognosis in cervical cancer – a review

Apart from clinical stage and lymph node status, acknowledged to be among the most powerful predictors of outcome in cervical cancer, the determination of prognosis and thereby the need for adjuvant therapy in surgically treated patients currently relies on a variety of histopathologic factors. The role of many of these is controversial. This may be because histopathology is genuinely lacking in sensitivity for predicting tumor behavior in vivo. There is, however, wide variation in histopathologic definitions and criteria. This is probably the major reason for both the lack of reproducibility in the reporting of certain factors and in their diminished value in predicting behavior. Tumor type, grade, vascular invasion, pattern of invasion, and depth are all extremely important prognostic indicators when used individually or as a part of a scoring system.     

Management of the third stage of labor in an Egyptian teaching hospital.

OBJECTIVES: The study describes normal labor practices in an Egyptian teaching hospital for the first time, where postpartum hemorrhage is the leading cause of maternal mortality. Third-stage management patterns are described and compared to evidence-based medicine. Reasons for third-stage practices observed are explored. STUDY DESIGN: 176 normal births were directly observed. Women were interviewed postpartum and study findings were shared with providers. RESULTS: Third-stage active management was correctly done for 15% of women observed. Most common deviations for the remaining 85% were: giving uterotonic drugs after placental delivery (65%) and without cord traction (49%). Passive management was not done for any observed delivery. CONCLUSIONS: The preventive role actively managing the third stage can provide against postpartum hemorrhage was lost to the majority of the deliveries observed. Obstacles to adopting protocols shown to reduce hemorrhage should be explored, given the contribution of postpartum hemorrhage to maternal deaths in Egypt.     

早期肾盂癌的诊断和诊断方法的比较

目的探讨早期肾盂癌的诊断和最有效的诊断方法。方法在诊断肾盂癌时采用B超、静注尿路造影(IVU)、逆行性肾盂造影、CT、泌尿系磁共振水成像(MRU)、输尿管肾盂镜检查等多种方法,比较各种方法对早期肾盂癌诊断的准确率。结果IVU和逆行性肾盂造影、CT、输尿管肾盂镜、MRU、B超对早期肾盂癌的诊断阳性率分别是89%、94%、80%、50%、40%和22%。结论IVU和逆行性肾盂造影是诊断早期肾盂癌最基本和最必要的有效检查方法,是其他方法不能代替的。因输尿管肾盂镜检查为有创性检查,故可作为疑难病例最后的确诊性检查方法,不宜做首选的检查方法。B超可作为普查之用。     

Oral misoprostol in the third stage of labor.

OBJECTIVE: To compare the efficacy of intravenous ergometrine, intramuscular oxytocin, and oral misoprostol in the control of postpartum hemorrhage. METHODS: Mean blood loss, rates of blood loss between 500 and 1000 ml, hematocrit fall greater than 10%, and need for additional oxytocic agents and nature and rates of adverse effects were assessed in this prospective, randomized, controlled study. RESULTS: All outcomes were similar in the 3 groups. The main adverse effects in the misoprostol group were temperatures higher than 99 degrees F, which normalized within 2 h and shivering, which was mild and self-limiting. CONCLUSIONS: Oral misoprostol is as effective as conventional oxytocic agents in preventing postpartum hemorrhage and can be recommended for use in low-resource settings.     

What is the difference between squamous cell carcinoma and adenocarcinoma of the cervix? A matched case–control study

The objective of this study was to investigate the efficacy of treatment strategies in patients with adenocarcinoma (AC) of the cervix and compare it with those with squamous cell carcinoma (SCC) of the cervix. Women with FIGO (1994) stage IB1 AC, especially pathologic tumor size of 2-4 cm, treated with class III hysterectomy, were compared with those with SCC treated with comparable strategy in a case-controlled study. Eighty patients (20 cases, 60 controls) were analyzed. Lymphvascular space invasion (P = 0.01) and lymph node metastasis (P = 0.07) were more frequent in patients with SCC than in those with AC. However, there was no significant difference in depth of stromal invasion (P = 0.51) and invasion of the parametrium (P = 0.44) between two groups. And there was also no statistically significant difference in disease-free survival (P = 0.86) and overall survival (P = 0.89) between two groups. Primary radical surgery followed by adjuvant therapy, same as for SCC, would be acceptable for AC with pathologic tumor size of 2-4 cm. Although it was difficult to determine whether AC recurred more systemically, more effective treatment strategies than those currently available for AC should be considered to reduce the systemic recurrence.     

正常儿童、青少年血清胰岛素样生长因子结合蛋白-3水平的变化

目的测定正常儿童、青少年血清胰岛素样生长因子结合蛋白-3(IGFBP-3)水平。方法对北京市东城区190名(男102名,女88名)健康的4.0~18.9岁儿童、青少年,应用放射免疫分析法(RIA)测定空腹血清IGFBP-3水平。结果随着年龄的增加,血清IGFBP-3水平逐渐升高,到青春期达到峰值。女性血清IGFBP-3水平达峰值时间较男性早1~2年,男、女性达峰时间分别为13.0~14.9及11.0~14.9岁,峰值分别为(4.58±0.64)、(4.67±0.93)mg/L。达峰值后血清IGFBP-3水平逐渐下降至各自9.0~10.9岁水平。血清IGFBP-3水平分别与身高和血清胰岛素样生长因-子1(IGF-1)水平呈显著正相关。结论血清IGFBP-3水平与年龄、青春发育期、身高及血清IGF-1水平明显相关。同年龄血清IGFBP-3水平无性别差异。     

Survival for rectal cancer patients and international comparisons.

BACKGROUND: Population-based cancer registry data are important because they reflect routine care, present long-term follow-up, can show differences in treatment, outcomes and health care over time, and can be used for comparisons between regions and countries. PATIENTS AND METHODS: Details of all cancer patients in the Munich region are recorded by the Munich Cancer Registry. Rectal cancer patients with an invasive primary tumor diagnosed between 1996 and 1998 were included in this analysis (n=936). Observed and relative survival are presented. Observed survival was also investigated with a Cox proportional hazards regression model. RESULTS: Median follow-up time of survivors was 5.7 years. Five-year relative survival for the whole sample was 62.2%. International Union Against Cancer (UICC) stage was the most important prognostic factor in the multivariate analysis. Compared with the 1992-1999 Surveillance Epidemiology and End Results (SEER) data (62.4%), relative survival for each disease stage and the whole sample were very similar. In comparison with other European registries, Munich patients had slightly higher survival rates per stage (for example, 5-year relative survival in UICC III was 58.3% in Munich, 54.6% in South East Netherlands, 33.3% in Modena and 47.4% in Cote d'Or); however, more patients in Munich were in higher disease stages with worse prognoses, indicating poorer early detection. CONCLUSIONS: These results indicate that treatment of rectal cancer in Munich is good, but early detection could be improved. Cancer registries should publish their population-based stage data to ensure quality of care and provide regular feedback to health-care workers and decision makers. Comparisons between countries without stage data should be conducted cautiously.
