Pregnancy, malignancy or mother nature? Persistence of high hCG levels in a perimenopausal woman.

Despite the fact that a small percentage of peri en postmenopausal women have mild elevations in human chorionic gonadotrophin (hCG) concentrations (<14 IU/L) besides high levels of gonadotrophins, a considerable number of clinicians are not aware of this phenomenon. We report a case of a 53-year-old woman with an unusually high hCG concentration (>40 IU/L) given her menopausal state. Although a pregnancy or a malignancy was unlikely on the basis of stable hCG levels, elevated gonadotrophins and a negative transvaginal ultrasound, her physicians were uncertain and chose an expectant approach by repeated testing.

Preoperative serum squamous cell carcinoma antigen levels in clinical decision making for patients with early-stage cervical cancer.

Purpose: To prevent morbidity associated with double modality treatment, early-stage cervical cancer patients should only be offered surgery when there is a low likelihood for adjuvant radiotherapy. We analyzed whether serum squamous cell carcinoma antigen (SCC-ag) analysis allows better preoperative identification of patients with a low likelihood for adjuvant radiotherapy than currently used clinical parameters.

Patients And Methods: In a cohort study, International Federation of Gynecology and Obstetrics (FIGO) stage, tumor size, and preoperative serum SCC-ag levels, as determined by enzyme immunoassay, were related to the frequency of postoperative indications for adjuvant radiotherapy in 337 surgically treated, FIGO stage IB/IIA, squamous cell cervical cancer patients.

Functional magnetic resonance imaging and control over the biceps muscle after intercostal-musculocutaneous nerve transfer.

Object: Recent progress in the understanding of cerebral plastic changes that occur after an intercostal nerve (ICN)-musculocutaneous nerve (MCN) transfer motivated a study with functional magnetic resonance (fMR) imaging to map reorganization in the primary motor cortex.

Methods: Eleven patients with traumatic root avulsions of the brachial plexus were studied. Nine patients underwent ICN-MCN transfer to restore biceps function and two patients were studied prior to surgery.

Clinical value of routine serum squamous cell carcinoma antigen in follow-up of patients with early-stage cervical cancer.

Purpose: To investigate the contribution to recurrence detection and survival of serum squamous cell carcinoma antigen (SCC-ag) analysis in the follow-up of early-stage cervical cancer patients.

Patients And Methods: Follow-up data were evaluated in patients with early-stage squamous cell cervical cancer treated by radical hysterectomy and pelvic lymphadenectomy with or without radiotherapy. Routine serum SCC-ag determination was performed at each follow-up visit.

Humoral immune response against proteins E6 and E7 in cervical carcinoma patients positive for human papilloma virus type 16 during treatment and follow-up.

To investigate the humoral immune response to transforming proteins E6 and E7 of human papillomavirus type 16 before and after treatment and during follow-up, consecutive serum samples from 36 cervical cancer patients whose tumours were found to contain human papillomavirus type 16 DNA by use of the polymerase chain reaction were tested using in vitro translated proteins E6 and E7 in a radioimmunoprecipitation assay and in an E7 synthetic peptide enzyme immunoassay. Antibody levels against E6 and E7 as measured by radioimmunoprecipitation assay showed a nearly identical pattern. Seronegative patients remained seronegative throughout treatment and follow-up.

The clinical value of squamous cell carcinoma antigen in cancer of the uterine cervix.

A review is given of the clinical use and interpretation of serum tumor marker levels during the treatment of patients with cancer of the uterine cervix. Pretreatment serum squamous cell carcinoma (SCC) antigen provides a new prognostic factor in early stage squamous cell carcinoma of the uterine cervix. Elevated serum values of SCC antigen at the time of diagnosis of stage IB and IIA cervical cancer indicate a 3 x increased risk of tumor recurrence, independent of tumor diameter, grade or the presence of lymph node metastases.

Detection of HPV-16 DNA by PCR in histologically cancer free lymph nodes from patients with cervical cancer.

The prognostic value of detection of human papillomavirus (HPV) type 16 DNA in histologically cancer free lymph nodes was assessed in left obturator lymph nodes from cervical cancer patients with HPV-16 positive primary tumours. HPV-16 DNA was detected by polymerase chain reaction in 12 of 35 patients with histologically cancer free lymph nodes. Of these 12 patients, only one developed a recurrence, suggesting HPV-16 DNA detection in cancer free lymph nodes has no prognostic value.

Relation between HPV-16 serology and clinico-pathological data in cervical carcinoma patients: prognostic value of anti-E6 and/or anti-E7 antibodies.

To investigate the clinical significance of the enhanced sensitivity of antibody detection by radio immunoprecipitation assays (RIPA), using in vitro translated HPV-16 E6 and E7 proteins, over synthetic-peptide enzyme-linked immunosorbent assay (ELISA), RIPA for HPV-16 E6 and E7 were performed. The results obtained with E6 and E7 RIPA were related to clinico-pathological data from cervical carcinoma patients positive for HPV type 16 DNA in their primary tumour. The data obtained with E6 and E7 RIPA were then compared to the results obtained using the E7/6-35 synthetic-peptide ELISA.

Comprehensive study of several general and type-specific primer pairs for detection of human papillomavirus DNA by PCR in paraffin-embedded cervical carcinomas.

We have compared the efficacies of three general primer pairs for the detection of human papillomavirus (HPV) DNA in formaldehyde-fixed paraffin-embedded carcinomas. The use of these primer pairs leads to underestimates of the HPV prevalence (GP5/6, 61.1%; CPI/IIG, 57.

Pretreatment serum squamous cell carcinoma antigen: a newly identified prognostic factor in early-stage cervical carcinoma.

Purpose: To investigate the prognostic value of pretreatment serum squamous cell carcinoma antigen (SCC-ag) levels in patients with cervical squamous cell carcinoma in relation to well-established conventional risk factors.

Patients And Methods: Sera from 653 women treated for squamous cervical cancer between 1978 and 1994 were analyzed for the presence of SCC-ag and related to clinicopathologic characteristics and patient outcome using univariate and multivariate analyses.

Results: Increased pretreatment SCC-ag levels correlated strongly with unfavorable clinicopathologic characteristics (International Federation of Gynecology and Obstetrics [FIGO] stages IB to IV [P < or = .

Antibodies to human papillomavirus type 16 E7 related to clinicopathological data in patients with cervical carcinoma.

Aims: To investigate the correlation between antibodies to the transforming protein E7 of human papillomavirus (HPV) type 16 and clinicopathological indices in women with cervical squamous carcinoma.

Methods: A synthetic peptide of the HPV type 16 E7 protein (amino acids 6 to 35) was used to screen sera from 29 children, 130 women with cervical intraepithelial neoplasia, 443 women with cervical cancer, and 222 controls, for antibodies against this viral antigen. Bivariate and multivariate analyses were used to investigate the correlation between the serological status in the pretreatment sera and clinicopathological indices (size of the lesions, histological grade, stomal infiltration, vascular invasion, and nodal spread).

Follow-up of antibody responses to human papillomavirus type 16 E7 in patients treated for cervical carcinoma.

A synthetic peptide comprising amino acids 6-35 of HPV-16 E7 was used in an ELISA to screen sera taken from 31 cervical carcinoma patients. Sera obtained before and during treatment, and in follow-up, were tested for the presence of antibodies to this peptide. Sixteen patients with negative pretreatment serum determination remained negative during treatment and follow-up.

CA 125 in serum and tumor from patients with uterine sarcoma.

Serial serum samples of 33 patients with primary sarcoma of the uterus were analyzed for CA 125 and frozen tissue sections of tumor from 23 patients were tested for this antigen. Before treatment, 12 of 30 evaluable patients showed serum CA 125 levels> 16 Uml-1 (40%). There was no relationship between serum CA 125 level and the histologic subtype.

Cancer of the uterine cervix: sensitivity and specificity of serum squamous cell carcinoma antigen determinations.

Between 1978 and 1989, 451 patients with cervical squamous cell carcinoma were referred to our department, of whom 143 experienced persistent or recurrent disease. Serial serum samples of the patients were analyzed for the presence of squamous cell carcinoma antigen (SCC). The incidence of elevated pretreatment serum SCC levels ranged from 37% in stage IB (N = 173) to 90% in stage IV (N = 19).

The effect of abdominal surgery on the serum concentration of the tumour-associated antigen CA 125.

The CA 125 assay is used to monitor the course of disease in women with adenocarcinoma of the genital tract. We measured serum CA 125 levels longitudinally in three different groups of patients who had normal serum CA 125 levels (less than or equal to 16 U/ml) before extensive intraperitoneal abdominal surgery (group 1, second-look laparotomy in 28 women with ovarian cancer; group 2, radical hysterectomy in 42 patients with cervical cancer; group 3, 13 men and one woman who had aortic surgery for atherosclerotic occlusive disease or aneurysm formation). Following surgery, rising serum CA 125 levels were observed in 69 out of the 84 patients (82%), irrespective of the primary diagnosis, type of operation or sex.

Adenocarcinoma of the uterine cervix. Prognostic significance of pretreatment serum CA 125, squamous cell carcinoma antigen, and carcinoembryonic antigen levels in relation to clinical and histopathologic tumor characteristics.

The prognostic value of the pretreatment serum CA 125, squamous cell carcinoma antigen (SCC), and carcinoembryonic antigen (CEA) levels in relation to tumor type, vascular invasion by tumor cells, and lymph node metastases was investigated in 77 patients with cervical adenocarcinoma. In Stage IB (International Federation of Gynecology and Obstetrics [FIGO]), the five-year actuarial survival of patients with pretreatment serum CA 125 levels greater than 16 U/ml was 52.4% versus 95.

Elevated levels of squamous cell carcinoma antigen in patients with a benign disease of the skin.

Squamous cell carcinoma antigen (SCC), formerly referred to as TA-4, is a tumor marker for SCC of the uterine cervix. Based on the findings in a patient with complete remission after treatment for cervical carcinoma, the authors decided to analyze the sera from patients with benign dermatoses. It was found that 83% (25/30) of the patients with psoriasis and 80% (12/15) of the patients with eczema had SCC levels in excess of the cut-off value of 2.

Tumor markers CA 125, squamous cell carcinoma antigen, and carcinoembryonic antigen in patients with adenocarcinoma of the uterine cervix.

Between 1978-1987, 439 patients with primary cervical carcinoma were admitted to our department. Seventy-seven patients (17.5%) had cervical adenocarcinoma and are reviewed in this retrospective study.

Serum CA 125 levels in patients with a provisional diagnosis of pelvic inflammatory disease. Clinical and theoretical implications.

In 50 patients with a provisional diagnosis of pelvic inflammatory disease (PID), CA 125 concentrations in serum were measured before laparoscopy and during hospitalization, using an enzyme immunoassay. The findings at laparoscopy were graded on the basis of the extent of inflammatory peritoneal involvement (grades 0-3; normal observations having a score of 0). On admission, 66% of the patients had serum CA 125 concentrations in excess of the cut-off value of 16 U/ml (range: 20-1300 U/ml).

CA 125: a useful marker in endometrial carcinoma.

In a retrospective study 121 patients with endometrial cancer were examined. In addition, 20 primary endometrial adenocarcinomas were tested immunohistochemically for CA 125. All tumor tissues were demonstrated to contain CA 125.

The tumor marker CA 125 is a common constituent of normal cervical mucus.

The presence of the tumor marker CA 125 was studied in the cervices of healthy women. Immunohistochemical staining of normal cervical tissue demonstrated the presence of CA 125 in the tall columnar cells of the endocervical epithelium but not in the ectocervical squamous epithelium. We measured very high levels of CA 125 in liquefied cervical mucus from women with regular menstrual cycles.
