Long-term significance of urinary neopterin in ovarian cancer: a study by the Austrian Association for Gynecologic Oncology (AGO).

BACKGROUND: Neopterin is produced by activated macrophages upon stimulation with interferon-γ (IFN-γ) and thus, elevated neopterin concentrations in patients indicate cellular inate immune response. Most studies in patients with malignant diseases found an association between higher neopterin concentrations and reduced survival and impaired prognosis. Nevertheless, neopterin is not a classical tumor marker since it is not produced by the cancer cells themselves. PATIENTS AND METHODS: In a study conducted by the Austrian Gynecologic Oncology Group (AGO) in 114 patients with ovarian cystadenomas and 223 patients with invasive ovarian cancer, patients' urinary neopterin was determined before and after primary therapy. The relevance of neopterin in long-term median follow-up was assessed. RESULTS: Elevated levels (cut-off 250 µmol/mol creatinine) were found less frequently in women with benign ovarian cystadenomas (24%) than in patients with malignant disease (58%). After 10 years, only 57% of ovarian cancer patients with elevated urinary neopterin levels survived without disease progression following primary therapy when compared with 86% of women with normal levels (P < 0.001). Along with residual tumor, FIGO stage, age and histological type, neopterin was significantly associated with overall survival (OS) and progression-free survival (PFS). The median PFS was 52 and 12 months and the median OS was 81 and 24 months for patients with normal and elevated neopterin, respectively, P < 0.001. In a multivariate Cox regression analysis, only residual tumor, neopterin and age were independently associated with OS, while only residual tumor was predictive for PFS. Thirty patients with early-stage invasive ovarian cancer (FIGO I and II) were analyzed separately. Of 3 patients with elevated neopterin, 2 died of disease in contrast to 2 out of 27 patients with normal neopterin (P = 0.004). CONCLUSION: In ovarian cancer, the negative impact of elevated urinary neopterin levels indicates a detrimental effect of cancer-associated inflammatory reaction.

Left ventricular function many years after recovery from pre-eclampsia.

OBJECTIVE: Epidemiological observations have shown that women with pre-eclampsia are at increased risk for subsequent development of cardiovascular disease. We evaluated maternal haemodynamics in asymptomatic women many years after pre-eclampsia and HELLP (haemolysis, elevated liver enzymes and low platelets) syndrome. DESIGN: Case-control study. SETTING: University-based department of obstetrics. POPULATION: Forty-eight women, 13-18 years after the affected pregnancy: 17 women with a history of HELLP syndrome, 14 women with a history of pre-eclampsia and 17 women following normal pregnancy (control group). METHODS: Echocardiographic examination was performed in all groups, recording the isovolumetric contraction time and isovolumetric relaxation time (ICT + IVRT), ejection time (ET), myocardial performance index (MPI), transmitral early to atrial filling velocity ratio (MV-E/MV-A), stroke volume (SV) and cardiac output (CO). MAIN OUTCOME MEASURES: Cardiac function. RESULTS: Women with previous HELLP syndrome showed a significantly increased MPI (0.34 versus 0.26; P = 0.008) and ICT + IVRT (442.16 versus 415.03; P = 0.01); MV-E/A, SV, ET and CO were not significantly different. Women with a history of pre-eclampsia showed a significantly increased MPI (0.36 versus 0.26; P = 0.006) and decreased ET (317.3 versus 328.93; P = 0.04); ICT + IVRT, MV-E/A, SV and CO were not significantly different. CONCLUSION: This study confirms epidemiological observations that women with pre-eclampsia are at increased risk for subsequent development of cardiovascular disease. Many years after HELLP syndrome or pre-eclampsia, asymptomatic women have an increased risk for impaired cardiac function as shown by an increased MPI.

Interferon-gamma in combination with carboplatin and paclitaxel as a safe and effective first-line treatment option for advanced ovarian cancer: results of a phase I/II study.

We have previously shown that interferon-gamma 1b (IFN-gamma) in combination with cyclophosphamide and cisplatin significantly prolongs progression-free survival in ovarian cancer. In this phase I/II study, we examined if administration of IFN-gamma is also safe in combination with the current standard treatment, paclitaxel and carboplatin. Thirty-four patients with newly diagnosed advanced epithelial ovarian cancer, FIGO stage III/IV, were treated for six to nine cycles with paclitaxel (175 mg/m(2)) and carboplatin (area under the curve [AUC] 5) every 3 weeks. IFN-gamma was administered in an escalating dose from 6 days/cycle with 0.025 mg sc up to 9 days/cycle with 0.1 mg sc. As expected, administration of IFN-gamma was associated with flu-like symptoms. Grade 3/4 neutropenia was observed in 74% (25 out of 34) of patients. Other side effects, in particular peripheral neuropathies, were within the previously observed ranges for the paclitaxel plus carboplatin combination. Overall response rate (complete or partial response) in patients who received either six or nine doses (0.1 mg) of IFN-gamma/cycle (n = 28) was 71%. IFN-gamma is safe in combination with carboplatin and paclitaxel for first-line treatment of patients with advanced ovarian cancer. This combination should be further evaluated as an immunotherapeutic treatment option for ovarian cancer.

[The evaluation of the second-look operation of patients with ovarian carcinoma and tubal carcinoma by means of a retrospective comparison study]. / Die Wertigkeit der Second-Look-Operation bei Patientinnen mit einem Ovarialkarzinom oder Tubenkarzinom mittels einer retrospektiven Vergleichsstudie.

INTRODUCTION: This investigation is a retrospective analysis to evaluate the influence of second-look surgery on the relapse-free and overall survival of patients with ovarian and tubal carcinomas. METHOD: For 208 patients with and without second-look operation out of 469 of the total collective, a matched analysis and a Cox regression model were established in the framework of a multivariate analysis. RESULTS: Second-look surgery in patients with ovarian cancer had no significant influence on the relapse-free and overall survival. The 10-year survival was equal in both groups: CONCLUSION: Second-look surgery cannot be justified on the basis of clinically noninvasive methods such as radiological findings with additional use of tumor markers. It should only be done in control clinical trials to evaluate new means of treatment.

Prognostic parameters in endometrial stromal sarcoma: a clinicopathologic study in 31 patients.

OBJECTIVE: The aim of this study was to evaluate the behavior of endometrial stromal sarcomas (ESS) in relation to their clinical and pathologic features and to identify possible prognostic factors. METHODS: Thirty-one patients with histologically proven ESS were included in the analysis. Endometrial stromal sarcoma is characterized by proliferations composed of cells with endometrial stromal cell differentiation. A breakpoint of 10 mitoses per 10 high-power fields was used in the statistical analysis to distinguish between low-grade and high-grade endometrial stromal sarcoma and to evaluate the prognostic value of mitotic count in patients with ESS. RESULTS: The median follow-up time was 72 months (range 34-110). The median overall survival of the 31 patients was 127 months, resulting in a 5-year overall survival rate of 62%. Adjuvant therapy was administered to 25 patients; among those, 20 patients received postoperative radiotherapy and 5 patients received chemotherapy. Ten of the irradiated patients and 3 patients undergoing chemotherapy developed disease recurrence. Concerning the response rate to adjuvant chemotherapy, 1 patient showed a complete response, 1 patient a partial response, 1 patient stable disease, and 2 patients progressive disease. Altogether, 14 patients developed recurrent disease with a median disease-free survival of 11 months (range 5-60). Twelve patients died of the disease. A univariate model revealed that early tumor stage (P < 0.0007), low myometrial invasion (P < 0.008), and low mitotic count (P < 0.005) were associated with a lengthened overall survival in patients with endometrial stromal sarcoma. Age and adjuvant therapy did not influence overall survival of patients with ESS. CONCLUSION: Early tumor stage, low myometrial invasion, and low mitotic count are associated with a lengthened overall survival in patients with ESS.

Significance of pretreatment serum hemoglobin and survival in epithelial ovarian cancer.

Tumor anemia is common in patients with malignant tumors and it was repeatedly demonstrated to be associated with impaired prognosis in patients with malignant tumors. We conducted a retrospective analysis based on 553 patients with histologically proven epithelial ovarian cancer. Blood hemoglobin levels were determined before surgery and patients with values <12 g/dl were considered anemic. Data analysis included univariate and multiple Cox models. Tumor anemia was present in 143 (25.9%) patients before surgery. Tumor anemia was present in 143 (25.9%) patients before surgery. In a multivariate Cox model, pretreatment hemoglobin values proved to be an independent prognostic factor for patients with stage I-II epithelial ovarian cancer (n=203), but failed to attain significance in patients with stage III-IV disease (n=350). Tumor anemia defined as pretreatment hemoglobin values <12 g/dl may indicate patients with stage I and II epithelial ovarian cancer, who are at increased risk of relapse.

Predictive value of uPA, PAI-1, HER-2 and VEGF in the serum of ovarian cancer patients.

BACKGROUND: Tissue levels of uPA, PAI-1, HER-2 and VEGF are known to have prognostic value in different malignant tumors. The prognostic potential of serum concentrations of these markers is less clear and was investigated. PATIENTS AND METHODS: The response to 2nd line chemotherapy was studied in 61 patients with recurrent ovarian cancer. Marker analyses were performed using specific and sensitive ELISA tests and the response to therapy was evaluated using multiple CA 125 determinations and including these values in a simple and comprehensive formula. RESULTS: Correlations were observed between VEGF and CA 125, HER-2 (inversely) as well as PAI-1, and between uPA and PAI-1. However, no marker showed a significant relation to the overall survival of patients, nor to treatment response. CONCLUSIONS: Serum levels of uPA, PAI-1, HER-2 and VEGF do not have enough predictive potential in recurrent ovarian cancer. Most likely additional sources contribute to the serum levels of the markers studied so that their levels are not only tumor specific.

Interferon-gamma in the first-line therapy of ovarian cancer: a randomized phase III trial.

Intraperitoneal treatment with interferon-gamma (IFN-gamma) has been shown to achieve surgically documented responses in the second-line therapy of ovarian cancer. To assess its efficacy in the first-line therapy, we conducted a randomized controlled trial with 148 patients who had undergone primary surgery for FIGO stage Ic-Illc ovarian cancer. In the control arm women received 100 mg/m(-2) cisplatin and 600 mg/m(-2) cyclophosphamide, the experimental arm included the above regimen with IFN-gamma 0.1 mg subcutaneously on days 1, 3, 5, 15, 17 and 19 of each 28-day cycle. Progression-free survival at 3 years was improved from 38% in controls to 51% in the treatment group corresponding to median times to progression of 17 and 48 months (P= 0.031, relative risk of progression 0.48, confidence interval 0.28-0.82). Three-year overall survival was 58% and 74% accordingly (n.s., median not yet reached). Complete clinical responses were observed in 68% with IFN-gamma versus 56% in controls (n.s.). Toxicity was comparable in both groups except for a mild flu-like syndrome, experienced by most patients after administration of IFN-gamma. Thus, with acceptable toxicity, the inclusion of IFN-gamm in the first-line chemotherapy of ovarian cancer yielded a benefit in prolonging progression-free survival.

Leiomyosarcoma of the uterus: a clinicopathologic multicenter study of 71 cases.

OBJECTIVE: The aim of this study was to evaluate the behavior of uterine leiomyosarcomas in relation to their clinical and pathologic features and to identify possible prognostic factors. METHODS: Seventy-one patients with histologically proven uterine leiomyosarcoma were included in the analysis. Leiomyosarcomas were defined as uterine smooth-muscle tumors with five or more mitoses per 10 high-power fields and cytologic atypia. Cox proportional hazards regression model was used to identify independent prognostic factors. RESULTS: The median follow-up time was 108 months; 5-year overall survival rate was 65%. Evaluating the correlation between several clinicopathologic parameters, tumors with vascular space involvement had a statistically significantly higher stage than tumors without vasular space involvement (P = 0.015). In a univariate Cox model early tumor stage (P < 0.0001), age <50 years (P < 0.0001), low mitotic count (P = 0.05), and the absence of vascular space involvement (P < 0.0005) were associated with good prognosis. In a multivariate analysis age (P = 0.002), tumor stage (P = 0.004), vascular space involvement (P = 0.003), and mitotic count in stage I tumors (P = 0.002) were found to be independent parameters for good prognosis in patients with uterine leiomyosarcoma. CONCLUSION: Early tumor stage, age <50 years, and absence of vascular space involvement were independently associated with good prognosis. Mitotic count was detected to be a strong prognostic parameter in early tumor stage, but failed to act as an independent prognostic parameter in patients with tumor stage II-IV disease.

Ovarian preservation in the surgical treatment of cervical carcinoma.

OBJECTIVES: In the surgical treatment of cervical carcinoma the conservation of ovaries in premenopausal women is a common procedure. To date, however, there have been no controlled studies to prove that the risk of recurrence or death from disease is not elevated among women who do not undergo oophorectomy. STUDY DESIGN: We performed a matched pairs analysis according to the tumor volume, comparing the outcomes of patients with in situ conservation of >/=1 ovary with those of control subjects who underwent bilateral oophorectomy. From among 658 patients, 150 pairs with International Federation of Gynecology and Obstetrics stage I disease were matched. Kaplan-Meier survival curves were compared with the log rank test. RESULTS: Among patients who retained their ovaries 5- and 10-year overall survival rates were 98% and 96%, respectively, versus 97% and 97% for the oophorectomy control group. The corresponding figures for progression-free survival were 95% and 94%, respectively, versus 97% and 93%. Outcomes were equal with sufficient power to detect a 10% difference. Three of 214 patients with conservation of ovaries (1.3%) subsequently required oophorectomy, all because of benign ovarian diseases. CONCLUSIONS: Our results confirm that ovarian conservation is safe in International Federation of Gynecology and Obstetrics stage I disease and that the occurrence of subsequent complications in ovaries retained in situ is rare.

[Induction of uterine contractions by Shigella]. / Induktion uteriner Kontraktionen durch Shigellen.

The uterus-contracting properties of Shigellae in a clinically relevant dose of 10(5) organisms per ml was investigated in 17 uterine strips which where dissected during caesarean section from the lower uterine segment. A highly significant (p < 0.001) increase in uterine activity was observed.

Erythropoietin treatment under polychemotherapy in patients with gynecologic malignancies: a prospective, randomized, double-blind placebo-controlled multicenter study.

In order to examine the influence of erythropoietin (rHuEPO) on serum hemoglobin levels, transfusion requirements, and quality of life in patients with gynecologic malignancies under polychemotherapy and chronic tumor anemia (hemoglobin <11 g/dl), we performed a prospective, randomized, double-blinded placebo-controlled clinical trial. Between October 1992 and October 1993, 35 patients from 5 gynecologic departments were entered into this trial. Inclusion criteria were hemoglobin level <11 g/dl, ferritin level >29 ng/ml, stool negative for occult blood, and life expectancy for more than 3 months. Patients received either 150 U/kg body wt rHuEPO (Erypo by Cilag-Janssen) sc three times a week for 12 weeks (n = 23) or a placebo (n = 12). If the hemoglobin levels of the 4th, 8th, or 12th week were >2 g/dl above the baseline value and/or >12 g/dl, the patient was classified as a responder. Patients who required blood transfusions (hemoglobin <8 g/dl, erythrocytes <3 x 10(6)/ml, or clinical symptoms of anemia) were classified as nonresponders. A nonvalidated quality of life questionnaire was completed by the patient at the beginning of the treatment and then every fourth week before receiving chemotherapy. In the rHuEPO group 56.6% of the patients responded to the treatment (chi2 = 10.79, P = 0.001) and only 5 patients (21.7%) required blood transfusions, whereas 8 of 12 patients in the placebo group (66.6%) had to be transfused (chi2 = 6.81, P = 0.009). Quality of life did not differ significantly between the rHuEPO group and the placebo group of patients. Within the rHuEPO group those patients that responded showed a significant increase in physical activity after response in comparison to the preresponsive phase (P = 0.02, paired t test). We therefore concluded that rHuEPO significantly increases serum hemoglobin levels and decreases transfusions requirements while maintaining quality of life in patients with gynecological malignancies who are undergoing polychemotherapy.

Parity as an independent prognostic factor in malignant mixed mesodermal tumors of the endometrium.

Malignant mixed mesodermal tumors (MMMT) are the most malignant neoplasms known to occur in the uterus. The most important prognostic factors are the extent of tumor at diagnosis, depth of myometrial invasion, and, as regarded by some authors, the sarcomatous component. We report on a retrospective analysis in 83 patients with MMMT. By univariate analysis survival was dependent on stage, depth of myometrial invasion, kind of therapy, age at menopause, and parity. However, the sarcomatous component did not significantly influence survival. Using the multivariate Cox regression analysis stage and parity or depth of myometrial invasion and parity were found to independently predict prognosis. Despite an interval of more than 20 years from the last childbirth to tumor appearance a beneficial influence of parity on the prognosis of MMMT was identified. This is unique in oncology. Especially patients with more than three children formed a subgroup of long-term survivors. It is interesting to note that parity was found by means of a Cox regression analysis to be statistically independent, and no correlation with other classical prognostic factors was detected.

Cisplatin resistance is associated with reduced interferon-gamma-sensitivity and increased HER-2 expression in cultured ovarian carcinoma cells.

In ovarian carcinoma cells, the combination of interferon-gamma (IFN-gamma) and cisplatin (cDDP) has been reported to result in a synergistic amplification of antiproliferative activity. To assess whether IFN-gamma may also prevent the occurrence of cisplatin resistance, the human ovarian carcinoma cell line HTB-77 was treated repeatedly in an intermittent fashion with either cisplatin alone (HTB-77cDDP) or cisplatin plus IFN-gamma (HTB-77cDDP + IFN). After 8 months of treatment, both new lines (HTB-77cDDP or HTB-77cDDP + IFN) were found to be three times more resistant to cisplatin than the wild-type cells (HTB-77wt). IFN-gamma could not prevent the development of cisplatin resistance. Interestingly, both HTB-77cDDP and HTB-77cDDP + IFN cells were also less IFN-gamma sensitive than the parental line. Both cisplatin-resistant lines expressed p185HER-2 and HER-2 mRNA at a higher concentration than the HTB-77wt cells. IFN-gamma was in all three HTB-77 cell lines able to suppress the HER-2 message and its encoded protein. The expression of IFN-gamma-induced antigens, namely CA-125 and class II antigens of the major histocompatibility complex (HLA-DR), was markedly augmented by IFN-gamma in all three lines, whereby the most prominent effect was seen in HTB-77cDDP and HTB-77cDDP + IFN.

Different effects of interferons, interleukin-1beta and tumor necrosis factor-alpha in normal (OSE) and malignant human ovarian epithelial cells.

Ovarian cancer arises mostly from the ovarian surface epithelium. The aim of our study was to compare the effects of cytokines in ovarian surface epithelial (OSE) cells and in ovarian carcinoma cells. Proliferation and expression of surface antigens (CA-125 and classes I and II antigens of the major histocompatibility complex [MHC]) were measured in OSE cells obtained from 7 different patients and 7 ovarian carcinoma cell lines. Proliferation of OSE cells remained unaffected by interferon (IFN)-alpha or IFN-gamma, whereas interleukin-1 (IL-1) and tumor necrosis factor (TNF) increased cell growth. Proliferation of ovarian carcinoma cells was reduced by both types of IFN as well as TNF but was not affected by IL-1. Expression of the tumor marker CA-125 was increased by IFN-gamma in ovarian carcinoma cells but not by any other treatment. None of the cytokines affected CA-125 surface expression in OSE cells. Expression of MHC-I was augmented in OSE and in carcinoma cells by both IFNs but not by the other cytokines. Both types of cell were negative for MHC-II, but IFN-gamma induced its expression in both OSE and carcinoma cells. Significant concentrations of the cytokines evaluated here have been measured in blood and follicular fluid by several authors. The different actions of these cytokines in OSE and carcinoma cells could therefore be important in understanding the role of such molecules in the regulation of physiological and pathological processes in the ovary, such as ovulation or malignant proliferation.

Circulating immunostimulatory protein 90K and soluble interleukin-2-receptor in human ovarian cancer.

The tumor-associated antigen 90K is thought to play an important role in cellular immune defense against malignant cells. It is therefore of interest to investigate whether circulating 90K could be used as a prognostic variable in ovarian cancer, and whether this immunostimulatory antigen is related to other parameters known to be involved in the cellular immune response. In the present retrospective study, circulating levels of antigen 90K were measured before primary surgery in 152 ovarian-cancer patients. A very close association between antigen 90K and s-IL-2R concentrations was pointed out in a stepwise logistic regression model. Univariate analysis of overall survival revealed that antigen 90K and s-IL-2R were associated with poor prognosis. In the multivariate Cox regression, however, neither antigen 90K nor s-IL-2R retained independent prognostic significance. Urinary neopterin was shown to be the only independent prognostic variable among the "immunological parameters" investigated. Additionally, residual disease after primary tumor debulking and histopathologic tumor grade were the most prominent clinico-pathologic parameters for the independent prediction of poor clinical outcome in ovarian-cancer patients.

Increased radiosensitivity by a combination of 9-cis-retinoic acid and interferon-y in breast cancer cells.

Interferons (IFNs) and retinoic acid (RA) are known to possess antiproliferative effects in various human cancer cell lines, including squamous cervix carcinoma and breast cancer cell lines. Frequently synergistic effects could be observed by the combination of both, and in clinical trials high response rates could be achieved by IFN-alpha in combination with 13-cis-RA in patients with squamous carcinoma of the uterine cervix. Since radiation-potentiating effects of IFNs and RA were described, we evaluated the additional impact of irradiation on three human breast cancer cell lines and investigated the antiproliferative effects of single, double, or triple treatments with IFN-gamma, 9-cis-RA, and irradiation. Antiproliferative effects were observed in all cell lines by any single treatment. When combining IFN-gamma with 9-cis-RA, synergism could be observed in all experiments. The combination of either IFN-gamma or 9-cis-RA with irradiation resulted mostly in additive effects. Irradiation contributed additive or further synergistic effects to the already synergistic effects of the combination of these two drugs. Thus synergism of IFN-gamma and 9-cis-RA always at least persisted fully. These results suggest that a regimen of IFN, RA, and radiotherapy (RT) might be a promising combination in the therapy of solid tumors, where RT is part of the conventional treatment.

Interaction of retinoic acid and interferon-alpha in breast cancer cell lines.

Retinoids and Interferons have been demonstrated to synergistically amplify the inhibition of proliferation in cultured breast cancer cells. Recently we reported that interferon-gamma (IFN-gamma) modulates the action of retinoic acid (RA): IFN-gamma increased expression of retinoic acid receptor-gamma (RAR-gamma) and suppressed the increase of retinoic acid binding protein type II (CRABP-II) expression. To improve the understanding of mechanism mediating synergism we extended our studies to the type I interferon-alpha. Synergistic inhibition of proliferation could be detected also by IFN-alpha and RA in BT-20 and SKBR-3 breast cancer cell lines but not in MCF-7 cells. Neither IFN-alpha nor any retinoid tested alone were able to increase RAR-gamma message, only the combination of both had this ability. In MCF-7 breast cancer cell lines the combination of any retinoid with IFN-alpha increased CRABP II expression level compared with the retinoids alone. In contrast with SKBR-3 and BT-20 cells a combination of ATRA with IFN-alpha markedly reduced ATRA mediated CRABP II induction. These results suggest that two factors may be responsible for synergistic action of RA and IFN-alpha: the inhibition of the CRABP II expression and an IFN-alpha/RA mediated upregulation of RAR-gamma.

[Role of the immune parameter neopterin in adnexitis]. / Bedeutung des Immunparameters Neopterin bei der Adnexitis.

Neopterin is a sensitive marker of macrophage activity, and elevated urine excretion has been observed in viral and bacterial infections. Including 48 patients, we investigated whether neopterin could be a valid parameter for classification of PID. Urinary Neopterin was determined pretherapeutically and throughout the follow-up by means of high pressure liquid chromatography. In about one third of the patients elevated levels of neopterin were observed and these were characterized by higher PID-scores, accelerated erythrocyte sedimentation rate and higher levels of C-reactive protein. The results indicate that in patients with PID macrophages are regularly activated. Neopterin may give additional information for classification of PID although because of lack of sensitivity and specificity it may not be helpful for differential diagnosis or follow-up of these patients.

[Ultrasound morphologic evaluation of the postmenopausal endometrium. A prospective study]. / Sonomorphologische Beurteilung des postmenopausalen Endometriums. Eine prospektive Studie.

OBJECTIVE: The measurement of the endometrial thickness by means of transvaginal sonography has been discussed as a tool for cancer screening. The aim of the study was to evaluate such a sonomorphological characterization of the endometrium performed by physicians in training. METHODS: A transvaginal sonography was performed in 400 patients before histological examination (dilatation and curettage or hysterectomy). The endometrial thickness measured as double layer and the sonographic patterns were determined. RESULTS: The endometrial thickness correlated with the histological findings: the median thickness was 6 mm for the normal endometrium and increased to 9 mm for polypiform hyperplasias 9.5 for cervical mucous polyps, and to 14 mm for glandular-cystic hyperplasias and carcinomas (p < 0.001 vs. normal). The sonomorphological grading score was also associated with the histology. For the sonomorphological grading, the sensitivity decreased to 80%, but the specificity increased to 62%. CONCLUSIONS: The sonomorphological pattern is superior to the sole determination of the endometrial thickness. This method is practicable under routine conditions performed by physicians in training. However, the specificity of both methods is too low to recommend them for cancer screening.
