- Seven tumour markers, i.e. squamous cell carcinoma antigen (SCC), cancer antigen 125 (CA 125), tissue polypeptide antigen (TPA), neopterin, C-reactive protein (CRP), carcinoembryonic antigen (CEA) and deoxythymidine kinase (TK) were analysed in sera from 104 women with benign and 61 women with malignant gynecologic diseases, in order to create tumour marker panels for various gynecologic malignancies, for monitoring and prediction of disease development. The incidence of elevated tumour marker levels, in cervical carcinoma was 78% when SCC, CA 125 and CEA were used. In ovarian carcinoma one of the markers CA 125, TPA and CEA was elevated in 91% and for endometrial carcinoma the best combination of markers was SCC, CA 125 and CEA (57%). No individual marker was superior to the above combinations. However, in patients with a fatal outcome of their malignant gynecologic disease (mean survival time from serum sampling was 16 months), the incidence of death was highest among those who had TPA elevated (91%) followed by neopterin (86%) and CRP (76%). Although intercurrent diseases affected tumour marker levels the markers picked up a majority of patients with a poor prognosis. This demonstrates the importance of interpreting tumour marker results against a background of detailed clinical information.

Familial and hormonal risk factors for papillary serous uterine cancer

Journal article (peer-reviewed)abstract
- Objectives: To identify genetic and non-genetic risk factors for papillary serous uterine cancer. Methods: A case-control study was conducted. Case women with papillary serous uterine cancer were compared with two control groups: 1) women with endometrioid uterine cancer and 2) healthy women with no past history of cancer. Cases and controls were matched for age (within two years) and ethnic group. All study subjects completed a questionnaire addressing family history. The cases and healthy controls were assessed for factors associated with estrogen exposure. Results: The risks of breast cancer (RR 1.84, Cl 1.03-331) and of prostate cancer (RR 2.21, CI 0.77-6.37) were higher among the relatives of patients with papillary serous uterine cancer, than among relatives of those with endometrioid uterine cancer. Other significant risk factors included weight at 18 years (p = 0.04) and the use of estrogen replacement therapy (p = 0.04). Conclusion: Relatives of women with papillary serous cancer of the uterus had an increased risk of breast and prostate cancer. Hormonal exposure also increases the risk for this cancer. These Findings suggest that predisposing genetic factors, possibly related to hormone metabolism, may be common to the three forms of cancer.

Lymph node sampling is of prognostic value in early stage epithelial ovarian carcinoma
- 2005

In: European journal of gynaecological oncology. - 0392-2936. ; 26:2, s. 181-185

Journal article (peer-reviewed)abstract
- PURPOSE:The importance of lymph node involvement as a prognostic factor is still under debate. In the present study, the impact of surgical staging for prognosis in early stages of epithelial ovarian cancer was evaluated in a series of 113 patients.MATERIAL AND METHODS:A retrospective study was carried out at the Department of Gynecological Oncology, Orebro University Hospital, during the period 1994-1998. In a subgroup of 20 out of 113 patients, pelvic lymph node sampling or pelvic lymphadenectomy was included in the standard surgical procedure. In cases of positive lymph nodes, the tumors were upstaged to FIGO Stage III. Pearson's chi-square, the t-test, the log-rank test and Cox multivariate analysis were used in the statistical analyses.RESULTS:The 20 patients with lymph node sampling or lymphadenectomy were compared with the remaining 93 patients without a comprehensive surgical staging procedure. A survival analysis demonstrated a significant (p = 0.005) difference in disease-free survival rates between the two subgroups, where there was a survival benefit in the subgroup of patients who had undergone comprehensive surgical staging. In a Cox proportional hazard regression analysis with disease-free survival as the endpoint, high tumor grade (HR = 3.14) and comprehensive surgical staging with at least a node sampling (HR = 0.09) were significant and independent prognostic factors.CONCLUSION:The benefit in survival after the procedure of lymph node sampling in early stages of epithelial ovarian carcinoma could probably be explained by the fact that the surgical procedure detects otherwise unrecognized Stage III disease.

Placental alkaline phosphatase (PLAP)/PLAP-like alkaline phosphatase as tumour marker in relation to CA 125 and TPA for ovarian epithelial tumours.
- 1990
-
In: European journal of gynaecological oncology. - 0392-2936. ; 11:5, s. 351-360
-
Journal article (peer-reviewed)abstract
- The significance of the PLAP (Placental alkaline phosphatase)/PLAP-like isozyme as tumour marker in relation to CA 125 and TPA for the monitoring of patients with malignant ovarian epithelial tumours was evaluated. Of all patients (n = 85), 40% had all three markers elevated. CA 125 being the most sensitive (60%), and the PLAP/PLAP-like isozyme and TPA both 40%. A tendency to certain tumour marker patterns of these three antigens in serum can be seen with regard to histopathology. Serous and anaplastic adenocarcinomas usually have all three markers moderately elevated, mucinous and mesonephric adenocarcinomas both have low incidences and low average levels of all three markers. Endometrioid and non-mucinous adenocarcinomas are often associated with high levels of the PLAP/PLAP-like isozyme and CA 125, while TPA shows moderate elevation. The PLAP/PLAP-like isozyme is positively correlated to tumour burden and the outcome of the disease. It may provide additional information on CA 125 in the monitoring of patients with ovarian cancer.

Pretreatment serum levels of C-reactive protein, alpha 1-antitrypsin, haptoglobin, alpha 1-acid glycoprotein and tissue polypeptide antigen in cervical carcinoma.

In: European journal of gynaecological oncology. - 0392-2936. ; 12:5, s. 375-383

Journal article (peer-reviewed)abstract
- In order to evaluate the potentially additive information of some acute phase reactants to that provided by a general tumour marker, pretreatment concentrations of C-reactive protein, alpha 1-antitrypsin, haptoglobin, alpha 1-acid glycoprotein and tissue polypeptide antigen were determined in serum from healthy women, patients with dysplasia/or carcinoma in situ and patients with primary cervical carcinoma. Specificity varied from 95-100% and sensitivity from 16-29%. A correlation with clinical stage was found for all analytes except for alpha 1-antitrypsin. The latter was the most frequently elevated analyte in early Stages (11/43 in Stage Ib/IIa) and uniquely elevated in 7 cancer patients. Although tissue polypeptide antigen predominantly signaled in advanced stages, 3 women in early stages had elevated tissue polypeptide antigen levels. One of these women died and she was also the only woman with raised alpha 1-antitrypsin who died. It is discussed whether elevated tissue polypeptide levels might represent an unfavourable sign for the individual and if alpha 1-antitrypsin is a favourable sign in early stages of cervical carcinoma. C-reactive protein results were obscured in early stages of disease by the presence of intercurrent illness and the results were regarded as inconclusive. Haptoglobin and alpha 1-acid glycoprotein concentrations provided no additional information to serum alpha 1-antitrypsin levels. However, haptoglobin was elevated in 64% (36/56) of the women with dysplasia/carcinoma in situ of the cervix uteri.
