The aim of the study was to evaluate the efficiency of low-field (0.14 T) magnetic resonance imaging (MRI) in the diagnosis and treatment of cancer of the cervix uteri. MATERIALS AND METHODS: Low-field MRI was performed in 39 patients with cancer of the cervix uteri to define the stage of the tumor and to follow up the outcomes of their treatment. Particular emphasis was laid on the determination of the size of the tumor and the presence of parametral invasion and on metastatic lesions of lymph nodes. MRI data were compared with clinical, morphological, and surgical staging results. In detecting the stage of cancer of the cervix uteri, the accuracy of MRI was 72% whereas that of clinical study was 51%. In determining parametral invasion, the accuracy of clinical study and low-field MRI was 71 and 90%, respectively. The sensitivity and specificity of MRI were 83 and 92%, respectively. The anterioposterior tumor size was an important prognostic factor in following up the outcomes of treatment as there was its close association and the incidence of tumor recurrences. The present study has indicated that the high efficiency of low-field MRI in detecting the stage of invasive cancer of cervix uteri makes it the method of choice in planning treatment and monitoring the outcomes of combined radiation therapy. 相似文献

To establish the role of co-overexpression of bcl-2 and c-myc protooncogenes in uterine cervix carcinogenesis, we examined 138 tissue samples of low grade cervical squamous intraepithelial lesions (SIL), high grade SIL, portio vaginalis uteri (PVU) carcinoma in situ and PVU carcinoma invasive, stage IA-IIA (study group) and 36 samples without SIL or malignancy (control group). The expression of bcl-2 and c-myc was detected immunohistochemically using a monoclonal antibody. Fisher’s exact test (P<0.05) was used to assess statistical significance. Overexpression of bcl-2 was found to increase in direct relation to the grade of the cervical lesions. High sensitivity was of great diagnostic significance for the detection of these types of changes in the uterine cervix. On the basis of high predictive values it can be said that in patients with bcl-2 overexpression there is a great possibility that they have premalignant or malignant changes in the uterine cervix. Co-overexpression of bcl-2 and c-myc oncogenes was found only in patients with PVU invasive carcinoma (6/26-23.0%). Statistically significant difference was not found in the frequency of co-overexpression in patients with PVU invasive carcinoma in relation to the control group (Fisher’s test; P=0.064). The method's sensitivity of determining these oncogenes with the aim of detecting PVU invasive carcinoma was 23%, while specificity was 72.2%. On the basis of high predictive values (100%), speaking in statistical terms, it can be concluded that all patients with co-overexpression of bcl-2 and c-myc oncogenes will have PVU invasive carcinoma. We confirmed in our research that co-overexpression of bcl-2 and c-myc oncogenes was increased only in PVU invasive carcinoma. However, a more extensive series of samples and additional tests are required to establish the prognostic significance of bcl-2 and c-myc co-overexpression in cervical carcinogenesis. 相似文献

False-negative Papanicolaou smears from women with cancerous and precancerous lesions of the uterine cervix 总被引:1,自引:0,他引:1
S Pairwuti 《Acta cytologica》1991,35(1):40-46
The occurrence from 1980 to 1989 of false-negative Papanicolaou smears in women with cancerous and precancerous lesions of the uterine cervix was studied. The 4,781 cases of cancer (2,814 invasive carcinomas and 593 carcinomas in situ) and precancerous lesions (418 severe dysplasias, 748 moderate dysplasias and 208 mild dysplasias) included 70 cases (1.5%) with false-negative smears. These 70 cases included 43 invasive carcinomas (61.4%), 17 carcinomas in situ and adenocarcinomas in situ (24.2%), and 10 dysplasias (14.4%); all were diagnosed histologically. The mean age of women with false-negative smears was 44.1 +/- 13.7 years. Review of the original cytologic samples showed a screening error in 41 cases (58.5%), an interpretation error in 2 cases (2.9%) and a sampling error in 27 cases (38.6%). Methods for eliminating false-negative smears are discussed. 相似文献

Can screening Chlamydia trachomatis by serological tests predict tubal damage in infertile patients?
Effectiveness of screening Chlamydia trachomatis (CT) antibody to predict tubal damage was assessed in this prospective study which was performed in a teaching hospital between September 2003 and September 2004. The study group consisted of 152 patients who underwent laparoscopy for infertility and the control group consisted of 80 fertile women who gave birth in the same hospital. CT antibody levels were measured by IFA (Indirect Fluorescence Assay for CT). Adhesions were defined by Gomel's classification system. Rate of seropositivity of CT was 34.6% in the study group and 22.5% in the control group (p>0.05). In the study group, the sensitivity, specifity, positive predictive and negative predictive values of CT positivity for tubal damage were 40%, 69.5%, 50% and 60.2% respectively. In the infertile group, the rate of tubal adhesion in the CT positive group was 50% and in the CT negative group it was 39.7% (p>0.05). However, there was a positive correlation between the severity of tubo-peritoneal adhesions and seropositivity for CT. In this study, we found out that tubo-peritoneal adhesions could not be predicted by the presence of CT inserum. There was a positive correlation between high CT seropositivity and high degree of adhesions. 相似文献

To investigate the clinical significance of ALDH2 genetic polymorphisms in cervical carcinogenesis. ALDH2 polymorphisms together with human papillomavirus (HPV) types were examined in a total of 195 cervical smear in exfoliated cervical cell samples using Real-Time polymerase chain reaction (PCR) System. The frequency for the AG+AA genotype was seven in the normal group (70.0 %), 16 in the LSIL group (57.1 %), and 27 in the HSIL group (90.0 %). A significant difference was found between the LSIL and HSIL groups (P = 0.0064). Patients with HSIL lesions frequently had high-risk HPV infections and concurrently belonged to the AG+AA group. ALDH2 genotype in cervical cell samples may be associated with more severe precancerous lesions of the cervix in a Japanese population. 相似文献

French uterine cancer recordings in death certificates include 60% of "uterine cancer, Not Otherwise Specified (NOS)"; this hampers the estimation of mortalities from cervix and corpus uteri cancers. The aims of this work were to study the reliability of uterine cancer recordings in death certificates using a case matching with cancer registries and estimate age-specific proportions of deaths from cervix and corpus uteri cancers among all uterine cancer deaths by a statistical approach that uses incidence and survival data. Deaths from uterine cancer between 1989 and 2001 were extracted from the French National database of causes of death and case-to-case matched to women diagnosed with uterine cancer between 1989 and 1997 in 8 cancer registries. Registry data were considered as "gold-standard". Among the 1825 matched deaths, cancer registries recorded 830 cervix and 995 corpus uteri cancers. In death certificates, 5% and 40% of "true" cervix cancers were respectively coded "corpus" and "uterus, NOS" and 5% and 59% of "true" corpus cancers respectively coded "cervix" and "uterus, NOS". Miscoding cervix cancers was more frequent at advanced ages at death and in deaths at home or in small urban areas. Miscoding corpus cancers was more frequent in deaths at home or in small urban areas. From the statistical method, the estimated proportion of deaths from cervix cancer among all uterine cancer deaths was higher than 95% in women aged 30-40 years old but declined to 35% in women older than 70 years. The study clarifies the reason for poor encoding of uterus cancer mortality and refines the estimation of mortalities from cervix and corpus uteri cancers allowing future studies on the efficacy of cervical cancer screening. 相似文献

Summary The frequency of sister chromatid exchanges (SCEs) was studied in leucocytes from 46 patients with cervical carcinoma, 89 precancerous lesions, and 43 age-matched control women. The frequency of SCEs was found to be 10.15 ±2.49 in cancer, 8.83±2.15 in precancerous lesions, and 7.55±2.24 in controls. The analyses of SCE data revealed a highly significant (P<0.001) increase in precancerous and cancerous lesions compared to controls. The intra-chromosomal distribution of SCEs revealed a random increase in various chromosomal groups in patients with cancer and dysplasia compared to controls. The mean SCE level among various groups of precancerous lesions according to severity of pathological condition did not show significant differences. However, 70.8% of dysplasia cases revealed SCE levels higher than the average in controls. The increased frequencies of SCEs in the majority of cancer patients and a few, precancerous lesions indicate that individuals with high SCE levels may be at a high risk of developing cancer. Thus the usefulness of SCE levels as a preclinical marker to identify the high risk group of dysplasias needs to be ascertained by follow-up studies; these are in progress. 相似文献
