Epidemiological characteristics and interruption of 228 HBV positive pregnant women / 公共卫生与预防医学

Objective To investigate the epidemiological characteristics and interruption of 228 hepatitis B virus (HBV) positive pregnant women, and to provide more references for clinical education and treatment. Methods A total of 228 chronic HBV pregnant women underwent maternal-neonatal transmission blocking treatment in Third Affiliated Hospital of Sun Yat-sen University from January 2015 to April 2019 were enrolled. Self-designed follow-up questionnaires were used to collect pregnant women's data. Then the relationship of epidemiological characteristics and HBV-DNA load levels with the genotype, hepatitis B e antigen (HBeAg), and alanine aminotransferase (ALT) was analyzed, moreover, the prevention of mother-to-child transmission was also analyzed. Results A total of 228 HBV-positive pregnant women were mainly over 30 years old, with a family history of liver disease, low education level (

Association of pretreatment thrombocytosis with prognosis in ovarian cancer: a systematic review and meta-analysis / 부인종양

OBJECTIVE: To investigate the association between pre-treatment thrombocytosis and prognosis in patients with ovarian cancer (OC). METHODS: PubMed, EMBASE, and the Cochrane Library were searched for articles regarding the prognosis of OC patients with pre-treatment thrombocytosis by the end of March 2018. Pooled estimates for overall survival (OS) and progression-free survival (PFS) events were calculated as hazard ratios (HRs) either on a fixed or random effect model by Stata 13.0 software. Funnel plot and Egger's test were applied to evaluate publication bias and sensitivity analyses were undertaken to estimate the strength of outcomes. RESULTS: Eleven studies that met the inclusion criteria were enrolled, including a total of 4,953 patients. Pooled results showed that pre-treatment thrombocytosis was significantly associated with OS (HR=1.722; 95% confidence interval [CI]=1.437–2.064) and PFS (HR=1.452; 95% CI=1.323–1.593) in the cohort. Significant correlation was found in OS and PFS between pre-treatment thrombocytosis and both epithelial OC (all stages and differentiation degrees of OC) and advanced epithelial OC (III or IV) by subgroup analyses, which were performed according to publication year, country, case numbers, OC category, International Federation of Gynecology and Obstetrics stage, and cut-off value. However, subgroup analyses indicated no significant correlation between pre-treatment thrombocytosis and OS for patients with high-grade serous (poorly differentiated or undifferentiated) OC (HR=1.220; 95% CI=0.946–1.573; p=0.125). Egger's test demonstrated no obvious publication bias in the articles enrolled in this study (OS: p=0.226; PFS: p=0.071). CONCLUSION: Pre-treatment thrombocytosis might be taken as an independent prognostic indicator for patients with OC.

Epidemiological features and trends of endometrial cancer: 10 081 cases analysis of 62 hospitals in Guangdong province / 中国医师杂志

Objective To explore the epidemiology characteristics of endometrial cancer (EC).Methods We retrospectively analyzed 10081 patients diagnosed with EC from 62 hospitals between 2000 and 2010 in Guangdong province.Results The mean age at diagnosis was 52.8 ± 9.3.The proportion were 19.3％,64.2％,16.6％ in patients with ages ≤45,＞ 45-60,＞ 60 respectively.From 2000 to 2010,the mean ages at each year were no statistic significance.The number of cases of EC were positively correlated with years(r =0.964,P ＜ 0.001).The number of cases of patients with ≤ 30 years old (r =0.857,P =0.001),≤35 years old (r =0.866,P =0.001),≤40 years old (r =0.952,P ＜ 0.001),≤ 45 years old (r =0.952,P ＜0.001) were positively correlated with years.The ratios of patients with ≤30 years old (x2 =10.390,P =0.407),≤35 years old (x2 =11.651,P =0.309),≤ 40 years old (x2 =17.329,P =0.067),≤45 years old (x2 =5.154,P =0.881) during these eleven years were no statistic significance.The ratios of type Ⅰ EC at 2000-2010 were no statistic significance.Conclusions EC often present in patients aged from ＞ 45-60 years old.The case number of EC showed an increasing trend.However,the proportion of young patients was stable.The endometroid adenocarcinoma was the main histological type of EC.

Comparative analyses of clinical and pathological characteristics between types 1 and 2 endometrial uterine cancers / 中国医师杂志

Objective To investigate the clinical and pathological characteristics between types 1 and 2 endometrial uterine cancers.Methods The clinical materials of 9 437 patients with uterine cancer were collected with retrospective analysis from 62 hospitals during 2000 to 2010.Results The mean age of type 1 endometrial cancers was less than type 2.There were more young patients in type 1 endometrial cancers.The mean menopause age of type 2 endometrial cancers was greater than type 1.The mean age of menarche,obesity,diabetes,hypertension,infertility,and nulliparous were not significant differences between types 1 and 2 endometrial cancers.There were more patients with advanced tumor,deep myometrium invasion,estrogen receptor (ERs) negative,progesterone receptor (PR) negative,P53 positive,lymph vascular space involvement,cervical stromal invasion,adnexal metastasis,and lymph node metastasis in type 2 endometrial cancers.Conclusions Type 2 endometrial uterine cancers occurred in elder people with more pathological risk factors and more malignant biological activities.

Value of hysteroscopy and dilatation and curettage in diagnosis of endometrial cancer / 中华妇产科杂志

Objective To evaluated the value of hysteroscopy and dilatation and curettage (DC) in diagnosis of endometrial cancer. Methods This retrospective analysis included clinical pathologic data of 3 676 patients with endometrial cancer from Jan. 1, 2000 to Dec. 31, 2010 in hospitals of endometrial cancer prevention projects in Guangdong Province. Results A total of 3 676 patients with endometrial cancer were divided into DC group (3 211 patients) and hysteroscopy group (465 patients). Compared to the results of pathological diagnosis, the accuracy rate between DC group and in hysteroscopy group were no statistically difference was 91.00%(2 922/3 211) vs 90.75%(422/465;χ2=0.030, P=0.862). The accuracy rate, sensitivity, specificity, positive predictive value and negative predictive value of cervical involvement between DC group and hysteroscopy group were 81.28%vs 86.45%(P0.05), 93.76%vs 98.71%(P0.05), respectively. Rate of positive peritoneal cytology in DC group was 4.76%(153/3 211), and the rate was 3.23%(15/465) in hysteroscopy group, which were no statistically difference (χ2=2.206, P=0.137). There were no statistically difference in 5-year overall survival (91.02% vs 92.03%;χ2=0.033, P=0.856) and 5-year progression-free survival (89.81%vs 91.83%;χ2=1.508, P=0.219) between DC group and hysteroscopy group. Conclusions Hysteroscopy and dilatation and curettage is an effective method in diagnosis of endometrial cancer, especially hysteroscopy is better in diagnosis of cervical involvement. Hysteroscopy don′t improve risks of positive peritoneal cytology and don′t affect the prognosis of patients with endometrial cancer.

Relationship between human papillomavirus gene types and cervi-cal diseases / 中国肿瘤临床

Objective: To investigate the relationship between human papilloma virus (HPV) gene types and cervical diseases. Methods:The subjects included women with HPV who were diagnosed in the Outpatient Department of the Third Affiliated Hospital of Sun Yat-sen University (Guangzhou, China) from March 1, 2010 to January 31, 2011. A total of 21 HPV DNA types were found in the women using DNA flow-though hybridization genotyping technique, and a questionnaire-type survey was conducted on these pa-tients. In this study, 256 cases of normal or inflamed cervix, 34 cases of cervical intraepithelial neoplasia I (CINⅠ), 61 cases of CINⅡor CINⅢ, and 9 cases of cervical cancer were analyzed. Results:The HPV infection rates were 18.4%in the normal cervical or inflam-mation group, 67.6%in the CINⅠgroup, 96.7%in the CINⅡor CINⅢgroup, and 100%in the cervical cancer group. The HPV in-fection rate was higher in the CIN I group than in the normal HPV infection or inflammation group (P<0.001) and was higher in the CIN Ⅱ or CIN Ⅲ groups than in the CIN I group (P<0.001). The main types of infection were HPV16 (44.2%), HPV58 (24.2%), HPV52 (11.6%), and HPV33 (8.4%) in the CIN groups. The main type of infection was HPV16 in the cervical cancer group (88.9%). Conclusion: Cases of cervical lesions are increasing. With this prevalence of HPV, considerable attention should be focused on HPV16-, 58-, 52-, and 33-related infections and cervical lesions. Among them, HPV16 infection is the primary cause of disease progres-sion and carcinogenesis.
