Symptoms and diagnosis of borderline, early and advanced epithelial ovarian cancer.

OBJECTIVE: To document symptoms associated with borderline, early and advanced ovarian cancer and identify personal characteristics associated with early versus late diagnosis. METHODS: Information concerning symptoms and diagnosis history was available from 811 women with ovarian cancer who took part in an Australian case-control study in the early 1990s. Women were classified into three groups for comparison based on their diagnosis: borderline, early (stage I-II) and advanced (stage III-IV) invasive cancer. RESULTS: Sixteen percent of women with borderline tumors, 7% with early cancer and 4% with advanced cancer experienced no symptoms before diagnosis (P < 0.0001). Among women with symptoms, abdominal pain (44%) or swelling (39%) were most frequently reported; an abdominal mass (12%) and gynecological symptoms (12%) were less common. Compared to advanced stage cancer, women with early stage cancer were more likely to report an abdominal mass or urinary symptoms but less likely to report gastrointestinal problems or general malaise. General malaise and 'other' symptoms were least common in borderline disease. Older women, and those with higher parity or a family history of breast or ovarian cancer, were more likely to be diagnosed at an advanced stage of disease. CONCLUSIONS: Women who experience persistent or recurrent abdominal symptoms, particularly swelling and/or pain should be encouraged to seek medical attention and physicians should be alert to the possibility of ovarian cancer even in the absence of an abdominal mass. Further information about the prevalence of these symptoms in the general population is essential to assist physicians in patient management.

Placental leucine aminopeptidase (P-LAP) and glucose transporter 4 (GLUT4) expression in benign, borderline, and malignant ovarian epithelia.

OBJECTIVE: Increased glucose consumption is a characteristic of malignant cells. Glucose is transported into the cell via facilitative glucose transporters, which are known to be members of a supergene family. The insulin-responsive GLUT4 isoform is expressed almost exclusively in insulin target tissues. P-LAP is a cell surface aminopeptidase, and is a synonym for oxytocinase. P-LAP is also referred to as insulin-regulated membrane aminopeptidase (IRAP) associated with GLUT4-containing vesicle. The authors evaluated P-LAP and GLUT4 expression in benign, borderline, and malignant ovarian epithelia. METHODS: Histologic sections of formalin-fixed, paraffin-embedded specimens from 11 patients with benign serous or mucinous cystadenomas, 14 patients with serous or mucinous borderline tumors, and 80 patients with epithelial-ovarian adenocarcinomas (29 serous, 17 endometrioid, 14 mucinous, and 20 clear cell adenocarcinomas) were stained for P-LAP and GLUT4 using each polyclonal antibody. Expressions of P-LAP and GLUT-4 in ovarian cancer cells were detected by Western blotting. RESULTS: P-LAP immunoreactivity was detected in 2 of 11 benign cystadenomas. None of the 11 benign ovarian tumors showed any immunoreactivity for GLUT4. Seven of 14 borderline tumors demonstrated P-LAP immunoreactivity, while 5 of 14 borderline tumors demonstrated GLUT4 immunoreactivity. P-LAP was expressed in 23 of 29 in serous, 15 of 17 endometrioid, 13 of 14 mucinous, and all clear-cell adenocarcinomas. The tendency toward increased P-LAP expression with advancing grade was observed in serous adenocarcinomas. GLUT4 was expressed in 13 of 29 serous, 13 of 17 endometrioid, 13 of 14 mucinous, and 18 of 20 clear-cell adenocarcinomas. In invasive carcinomas, there was a direct correlation between P-LAP immunoreactivity and GLUT4 immunoreactivity (correlation coefficient [r] = 0.58; P < 0.01). Furthermore, P-LAP overexpression in SKOV3 cells induced the GLUT4 expression. CONCLUSIONS: P-LAP and GLUT4 are available not only for the evaluation of ovarian epithelial malignancy, but also as targets for molecular therapy. Further study to investigate the roles of P-LAP and GLUT4 in ovarian carcinoma is needed.

Results of the national survey of borderline ovarian tumors in Spain.

MATERIAL AND METHODS: Retrospective multi-center analysis of women diagnosed with borderline ovarian tumor and treated between January 1990 and December 1997. A national survey was conducted, in which 457 patients from 27 centers corresponding to ten of Spain's autonomous communities were analyzed. RESULTS: Four hundred fifty-seven women with borderline ovarian tumor were analyzed. The mean age of patients was 45.5+/-16.9 years. Of these, 390 patients (85.3%) were at stage I, 8 (1.8%) were at stage II and 36 (7.9%) at stage III. A bilateral tumor was observed in 63 women (13.8%). The mean tumor size was 14.2 cm and in 88 cases (19.3%) the tumor was on the surface of the ovary. Microinvasion was observed in 25 (5.5%) cases, and 29 women (6.3%) showed a micropapillary pattern. Study of the factors related to the appearance of peritoneal implants revealed positive tumor markers (OR 15.02: 1.9-32.9) and a tumor on the ovarian surface (OR 8.0: 1.8-127) to be independent risk factors. With respect to recurrence, the presence of peritoneal implants at the time of initial surgery (OR 3.4: 1.1-10.4) and signs of microinvasion in the anatomicopathological study (OR 5.5: 1.5-17.8) were found to be independent risk factors. The overall survival rate in our series was 97% with a mean follow-up of 88.3 months. The survival rate by stage was 97% for stage I, 100% for stage II and 97% for stage III. CONCLUSIONS: Although borderline ovarian tumors have an excellent prognosis, they are not exempt from a risk of recurrence. Characterization of patients with borderline ovarian tumor is essential in order to prevent their evolution. Likewise, the taking on board of risk factors will enable more selective treatments to be offered in each case.

Cancer among first-degree relatives of probands with invasive and borderline ovarian cancer.

OBJECTIVE: The familial clustering of ovarian, breast, endometrial, colon; and prostate cancer was compared in first-degree relatives of probands with invasive and borderline ovarian cancer to determine coaggregation. METHODS: Probands (n=392), who had been patients in the Division of Gynecologic Oncology at Washington University, were ascertained consecutively. Family history on 2192 first-degree relatives was collected by personal interviews of the probands and other family members. Estimates of prevalence of cancers in first-degree relatives of the two proband groups were compared. Survival analysis was used to examine the age-at-onset distribution of each cancer in relatives of invasive probands versus relatives of borderline probands. RESULTS: Among the relatives were 24 cases of ovarian cancer, 46 cases of breast cancer, 13 cases of endometrial cancer, and 25 and 28 cases of colon and prostate cancer, respectively. There were no significant differences in the prevalence of any of these cancers in relatives of the invasive and borderline probands. Cumulative lifetime risk estimates did not differ between the relatives of the two groups for any cancers. Age-at-onset of ovarian cancer did not differ between probands with positive family histories of the five cancers and those with negative histories. The inability to reject the null hypothesis of no differences in the first-degree relatives of our two study groups might be from insufficient power to detect small differences, given our sample size. CONCLUSION: These results suggest that relatives of patients with invasive and borderline ovarian cancer might share similar cancer risks and age-at-onset distributions.

Outcome and reproductive function after conservative surgery for borderline ovarian tumors.

OBJECTIVE: To study reproductive function and disease outcome in women with borderline ovarian tumors who were treated with conservative surgery. METHODS: Patients with borderline ovarian tumors were identified from institutional databases. Patients were eligible if they had pathologically confirmed borderline ovarian tumors, no prior sterilization, no history of radiation therapy, retained their uterus and ovarian tissue, and were younger than age 45. Information was acquired by retrospective medical record review and patient interview. RESULTS: Forty-three patients met the eligibility criteria. The median age was 25 years, with a range of 15-39 years. Twenty-six patients had serous tumors, and 17 had mucinous tumors. Fifteen had stage I disease, three had stage III, and 25 were unstaged. Follow-up was available for all patients (median, 5.7 years). Twenty-nine remained disease-free, and 14 developed a new primary lesion/recurrence, with a median time to recurrence of 39.3 months. Recurrence was more frequent in patients treated with ovarian cystectomy than in those treated with oophorectomy alone (58% compared with 23%) (P <.04). After treatment, 29 of 36 patients (81%) retained normal menstrual cycles, and 12 of 24 patients attempting pregnancy conceived 25 pregnancies. Most patients were highly satisfied with conservative surgery. CONCLUSION: Conservative surgery remains a therapeutic option in selected patients with borderline ovarian tumors. Although the rate of new lesion/recurrence is relatively high, especially in those treated with ovarian cystectomy, mortality from cancer remains low. Many patients who desire pregnancy are able to conceive and deliver healthy offspring after conservative surgery.

Surgery as sole treatment for serous borderline tumors of the ovary with noninvasive implants.

OBJECTIVES: The objectives were to describe the clinical characteristics and prognosis of surgically treated patients with stage II and III serous borderline tumors of the ovary with noninvasive implants. MATERIALS AND METHODS: From 1990 to 2000, 16 patients with stage II and III ovarian serous borderline tumors and noninvasive implants were diagnosed and prospectively followed at our center. All patients underwent surgical treatment including staging and their pathology was reviewed. Fifteen patients had thorough surgical staging by laparotomy, while one patient was staged laparoscopically. No patient was treated with adjuvant therapy (radiation or chemotherapy) after surgical treatment and none were lost to follow-up. RESULTS: The mean age at diagnosis was 42 years (range 26-59). Fourteen patients were treated by abdominal hysterectomy, bilateral salpingo-oophorectomy, omentectomy, and multiple peritoneal biopsies, while 2 patients were treated conservatively for fertility preservation. Two patients underwent pelvic and para-aortic lymph node dissection. Fifteen of 16 patients had ovarian surface involvement with tumor. All patients but 2 had clinical evidence of extraovarian disease at the time of surgery. The mean duration of follow-up was 60.7 months (range 2-134 months). Thirteen patients (81%) are alive without evidence of disease. Four patients (25%) required subsequent surgery for recurrent disease and all are still alive. Two patients have been treated with chemotherapy (paclitaxel/carboplatin) for progressive borderline disease, while an additional patient was treated after first relapse with chemotherapy for an invasive recurrence. CONCLUSIONS: Carefully staged patients with advanced serous borderline tumors of the ovary and noninvasive implants have a good prognosis without adjuvant therapy.

Karyotypic characteristics of borderline malignant tumors of the ovary: trisomy 12, trisomy 7, and r(1) as nonrandom features.

Clonal karyotypic abnormalities were detected in five of 14 cytogenetically analyzed borderline malignant ovarian tumors of clinical stages I-II. One mucinous and one seropapillary tumor had trisomy 7 and r(1)(p36q42) as the sole chromosome abnormality, respectively. Trisomy 12 was found in the remaining three cases. It was the only change in one mucinous and one serous tumor, whereas the third, a seropapillary borderline tumor, had the karyotype 49,XX,+5,+8, +12. These findings, especially when collated with those of previous reports on ovarian borderline tumor cytogenetics, indicate that +12 is the most consistent chromosomal aberration in this group of neoplasms and that also +7 and r(1) are nonrandom features. From the karyotypic point of view, benign ovarian tumors and well-differentiated carcinomas are similar to borderline ovarian tumors, with the possible exception that the former have no tendency to form r(1). Highly malignant carcinomas, on the other hand, are typically much more complex. Chromosome-level changes therefore cannot account for the putative phenotypic passage through the most innocuous tumor stages as epithelial ovarian neoplasms go from benign to fully malignant.

Developmental dissociation, deviance, and delay: Occurrence of attention-deficit-hyperactivity disorder in individuals with and without borderline-to-mild intellectual disability.

A neurodevelopmental model for understanding the spectrum of developmental disabilities postulates that developmental delay, dissociation, and deviance reflect underlying central nervous system dysfunction. In this study, we determined the occurrence of the dissociated and developmentally deviant behavioral profile of attention-deficit-hyperactivity disorder (ADHD) among children with and without developmental cognitive delays (borderline-to-mild intellectual disability) in a population-based birth cohort (n = 5718). Among the 70 children identified to have borderline-to-mild intellectual disability, 30% (n = 21; 7 females, 14 males) met research criteria for ADHD, compared to only 6.4% of children without intellectual disability (n = 358; 88 females, 270 males). The odds ratio for comorbid ADHD for children with versus without borderline-to-mild intellectual disability was 6.3 (95% confidence interval: 3.7-10.6; p < 0.001). These data illustrate that developmental dissociation and/or deviance, as represented by ADHD, are more likely to occur in the context of developmental delay, represented by borderline-to-mild intellectual disability.

Vascular compliance in sodium-sensitive and sodium-resistant borderline hypertensive patients.

Recently, we demonstrated a reduction in the compliance of the carotid, femoral and brachial arteries in sodium-sensitive subjects who had consumed a regular sodium intake of approximately 120 mmol per day, as compared to both sodium-resistant borderline hypertensive subjects and normotensive controls. Venous compliance was not different between the two borderline hypertensive groups and was only slightly lesser than in controls. Large artery compliance was studied using a non-invasive ultrasound vessel wall movement detector system, while venous compliance was determined by means of strain gauge plethysmography. The borderline hypertensive subjects were subsequently treated with enalapril 10 mg/day, felodipine 5 mg/day or placebo during six months. Despite similar reductions in blood pressure, enalapril induced a significant increase of the muscular femoral and brachial artery compliance, but not of the elastic carotid artery, while felodipine did not influence large artery compliance at all in the sodium-sensitive group. The effect of enalapril on muscular artery compliance was established through a dose-dependent increase in distension and not through a change in arterial diameter. Arterial compliance was not influenced by either of the drugs in the resistant group. Venous compliance was also not altered by the medication. In conclusion, femoral and brachial artery compliance in sodium-sensitive borderline hypertensive subjects, which was found to be lower than that of sodium-resistant subjects, improved with antihypertensive treatment with enalapril but not with felodipine, despite the similar reductions in blood pressure induced by both drugs.(ABSTRACT TRUNCATED AT 250 WORDS)

BRCA1 mutations in ovarian cancer and borderline tumours in Norway: a nested case-control study.

The aims of the present study were to find the frequency of the most common BRCA1 mutations in women with ovarian tumours identified from a population-based cancer registry and in the general population, to estimate the relative risk of ovarian tumours among the mutation carriers, and to explore the value of using CA125 as a prediagnostic test. The study was designed as a nested case-control study within a cohort mainly consisting of participants in population-based health examinations. The data files of The Cancer Registry of Norway and the Janus serum bank were linked to identify cases with ovarian cancer and borderline tumours. Hereditary BRCA1 mutations were determined using archived serum samples and capillary electrophoresis. Altogether 478 ovarian cancer patients and 190 patients with borderline tumours were identified, and 1421 and 568 matching controls were selected. Odds ratios (OR) of developing ovarian cancer and borderline tumours in the presence of BRCA1 mutations and CA125 level were derived from conditional logistic regression models. Among the 478 ovarian cancer patients, 19 BRCA1 mutations were identified (1675delA, 1135insA, 816delGT and 3347delAG), none among the patients with borderline tumours. Only two of the 1989 controls were BRCA1 mutation carriers (0.10%). The risk of ovarian cancer among the mutation carriers was strongly elevated (OR=29, 95% CI=6.6-120). CA125 was a marker for ovarian cancer, but the sensitivity was low. This study showed that BRCA1 mutation carriers have a very high risk of ovarian cancer. However, since the prevalence of BRCA1 mutations in the Norwegian population was low, the proportion of ovarian cancers due to BRCA1 mutations seemed to be low, about 4%. The sensitivity of using CA125 only as a screening test for ovarian cancer was low.

Neonatal outcome when delivery follows a borderline immature lecithin to sphingomyelin ratio.

OBJECTIVE: Occasionally, clinicians are presented with a complicated preterm pregnancy where fetal pulmonary maturity testing might be used to help guide management decisions. However, should delivery be allowed if the lecithin to sphingomyelin ratio (L/S ratio) is not quite mature? The incidence of newborn complications after delivery with L/S ratio values of 1.8 and 1.9 is unknown. The purpose of this study was to evaluate the neonatal morbidity and mortality in patients that delivered with these borderline immature results. STUDY DESIGN: All patients who underwent fetal pulmonary maturity testing were prospectively recorded in log books. An L/S ratio of > or = 2.0 was considered mature. Patients with an L/S ratio of 1.8 or 1.9 were considered "borderline immature." These borderline immature cases were evaluated for the gestational age at amniocentesis, the gestational age at delivery, and neonatal outcome. RESULTS: During the 9-year study period, L/S ratio testing was performed on 2038 patients. Of these, 162 preterm patients (7.9%) had an L/S ratio of 1.8 or 1.9 A total of 63 of these 162 patients delivered < 72 hours after the amniocentesis and met study criteria. The pregnancies ranged from 27 to 36 weeks' gestation. There was a 13% incidence (95% confidence interval (CI) of 4% to 30%) of major neonatal morbidity and a 3% incidence (95% CI of 0% to 17%) of neonatal mortality in the 30 pregnancies with an L/S ratio of 1.8. The incidence of major neonatal morbidity was only 3% (95% CI of 0% to 15%) in the 33 patients with an L/S ratio of 1.9, with no cases of mortality (95% CI of 0% to 9%). CONCLUSION: Based on 95% CIs, the data of this study reveal that the maximum risk for major morbidity is < or = 15%, with a mortality risk of < 10% in a preterm newborn delivered with a 1.9 L/S ratio value. The maximum risk is 30% for major morbidity and 17% for mortality in preterm newborns delivered with a 1.8 L/S ratio. This information may help in the decision-making process of whether to deliver or to observe when faced with a borderline immature L/S ratio result in a complicated preterm pregnancy.

A one centimorgan deletion unit on chromosome Xq12 is commonly lost in borderline and invasive epithelial ovarian tumors.

We have used polymerase chain reaction (PCR) amplification of tandem repeats to study the pattern of allelic loss on chromosome X11.2-q12 in borderline and invasive epithelial ovarian tumors. Using eight microsatellite markers spanning Xq11.2-q12, 41 borderline and 65 invasive ovarian tumors, together with their corresponding normal tissues, were analysed. The highest percentage of loss of heterozygosity (LOH) was observed at the DXS1194 locus in borderline tumors (four of 16 informative cases, 25%) and at the androgen receptor (AR) locus in invasive epithelial ovarian tumors (18 of 47 informative cases, 38%). X chromosome activation studies performed in cases with LOH at the AR locus showed that the allelic loss at the AR locus is not confined to the inactive allele. A one centimorgan region including the AR locus and flanked by the primers DXS1161 and PGK1P1 was identified as the smallest common loss region in both borderline and invasive epithelial ovarian tumors.

Exercise blood pressure and baroreflex function in borderline hypertensive and normotensive young men.

1. Resting carotid baroreflex sensitivity and blood pressure responses to standardized conditions of rest and exercise were measured in 17 borderline hypertensive males and 12 normotensive males. 2. The borderline hypertensive group had significantly higher systolic and diastolic blood pressures during orthostatic rest and isometric handgrip exercise and higher systolic blood pressure during supine rest and submaximum and maximum treadmill exercise. 3. The borderline hypertensive group had an attenuation of baroreflex sensitivity compared with the normotensive group. Resting baroreflex sensitivity was significantly correlated with absolute systolic blood pressure during supine rest, orthostatic rest, isometric handgrip exercise and submaximum treadmill exercise. 4. The results indicate that blood pressure is regulated at a significantly higher level during rest and exercise in borderline hypertension and is associated with reduced baroreflex sensitivity measured at supine rest.

Standard setting in an objective structured clinical examination: use of global ratings of borderline performance to determine the passing score.

BACKGROUND: Objective structured clinical examination (OSCE) standard-setting procedures are not well developed and are often time-consuming and complex. We report an evaluation of a simple 'contrasting groups' method, applied to an OSCE conducted simultaneously in three separate schools. SUBJECTS: Medical students undertaking an end-of-fifth year multidisciplinary OSCE. METHODS: Using structured marking sheets, pairs of examiners independently scored student performance at each OSCE station. Examiners also provided a global rating of overall performance. The actual scores of any borderline candidates at each station were averaged to provide a passing score for each station. The passing scores for all stations were combined to become the passing score for the whole exam. Validity was determined by making comparisons with performance on other fifth-year assessments. Reliability measures comprised interschool agreement, interexaminer agreement and interstation variability. RESULTS: The approach was simple and had face validity. There was a stronger association between the performance of borderline candidates on the OSCE and their in-course assessments than with their performance on the written exam, giving a weak measure of construct validity in the absence of a better 'gold standard'. There was good agreement between examiners in identifying borderline candidates. There were significant differences between schools in the borderline score for some stations, which disappeared when more than three stations were aggregated. CONCLUSION: This practical method provided a valid and reliable competence-based pass mark. Combining marks from all stations before determining the pass mark was more reliable than making decisions based on individual stations.

The transition out of medical school - a qualitative study of descriptions of borderline trainee interns.

OBJECTIVE: To describe the characteristics of borderline performance in final year medical students (trainee interns), as judged by their supervisors. DESIGN: Qualitative study based on in-depth interviews followed by validation descriptions of borderline trainee interns identified prospectively over 12 months. SETTING: Christchurch School of Medicine, University of Otago, New Zealand. PARTICIPANTS: Fourteen supervisors of trainee interns chosen because of their experience and/or close contact with trainee interns. MAIN OUTCOME MEASURES: Analysis of supervisors' narratives to identify key themes. RESULTS: Borderline trainee intern performance occurs within a transition period from clinical student to doctor and is characterised by difficulty taking on a professional role. This difficulty may be manifest by not getting involved with the health care team, poor time management and occasionally by interpersonal difficulties or not recognising limits. Taking on a professional role requires ability in the clinical task, including diagnostic ability, which is built on a foundation of basic knowledge and clinical skills. These can be influenced by personal factors such as rigidity, motivation and shyness. Personal illness can affect performance at any stage. CONCLUSIONS: The difficulties faced by borderline trainee interns fit a model of transition from competence as a student to performance as an intern. A sensitive marker of such difficulties is poor time management or not getting involved with the patient care team. Such difficulties may reflect more specific problems such as professional socialization, setting priorities, hypothesis generation, assigning probabilities to identified problems, integrating competing issues, recognising limits and learning when to call for assistance.

A comparison of ambulatory and conventional urodynamic studies in men with borderline outlet obstruction.

OBJECTIVE: To compare detrusor function and outlet behaviour on ambulatory urodynamic monitoring (AUM) with conventional cystometrography in symptomatic men with borderline evidence of bladder outlet obstruction (BOO), as determined by conventional cystometrography, and to assess the usefulness of AUM in reclassifying this population of patients into obstructed and unobstructed groups. PATIENTS AND METHODS: Sixty-nine consecutive men (mean age 59.6 years) with lower urinary tract symptoms (mean International Prostate Symptom Score 19.1) and borderline BOO on a medium-fill conventional urodynamic study (CUS) were examined prospectively with AUM. Detrusor contractility, obstruction grade, maximal voiding detrusor pressure (pdet(max)), detrusor pressure at peak flow (pdet Qmax) and peak flow rate (Qmax) determined by both methods were compared. The incidence of detrusor instability (DI) detected by both modalities was also evaluated. RESULTS: There was considerable disagreement between the investigations during the voiding phase. Detrusor contractility was higher on AUM than on CUS (P= 0.003) and obstruction grade was significantly lower on AUM (P=0.018). There was no difference in pdet(max) nor pdet Qmax. The mean (95% confidence interval) Qmax was higher on AUM, at 12.9 (1.3) mL/s, than on CUS, at 8.9 (0.8) mL/s. On the Abrams-Griffiths nomogram the most significant changes were six men (10%) from equivocal to obstructed, seven (11%) from equivocal to unobstructed and two (3%) from obstructed to unobstructed on CUS and on AUM, respectively. Thus, in 24% of patients there was a potentially clinically significant change resulting from the information generated by AUM. DI was identified on CUS in 26 (41%) men and on AUM in 25 (40%); 35 men (56%) had evidence of DI on either AUM or CUS. CONCLUSION: The significant disagreement between the findings on CUS and AUM suggests that the conditions under which pressure-flow investigations are carried out significantly affect findings in borderline cases. The reclassification of patients by AUM into obstructed and unobstructed groups occurs in 24% and may be clinically relevant. AUM appears to be complementary to CUS in the assessment of men who are borderline for obstruction on conventional testing, but the clinical implications of this have yet to be determined.

Prognostic significance of cell cycle proteins and genomic instability in borderline, early and advanced stage ovarian carcinomas.

Disturbed cell cycle-regulating checkpoints and impairment of genomic stability are key events during the genesis and progression of malignant tumors. We analyzed 80 epithelial ovarian tumors of benign (n = 10) and borderline type (n = 18) in addition to carcinomas of early (n = 26) and advanced (n = 26) stages for the expression of Ki67, cyclin A and cyclin E, p21WAF-1, p27KIP-1 and p53 and correlated the results with the clinical course. Genomic instability was assessed by DNA ploidy measurements and, in 35 cases, by comparative genomic hybridization. Overexpression of cyclin A and cyclin E was observed in the majority of invasive carcinomas, only rarely in borderline tumors and in none of the benign tumors. Similarly, high expression of p53 together with undetectable p21 or loss of chromosome arm 17p were frequent events only in adenocarcinomas. Both borderline tumors and adenocarcinomas revealed a high number of chromosomal gains and losses. However, regional chromosomal amplifications were found to occur 13 times more frequently in the adenocarcinomas than in the borderline tumors. The expression pattern of low p27 together with high Ki67 was found to be an independent predictor of poor outcome in invasive carcinomas. The results provide a link between disturbed cell cycle regulatory proteins, chromosomal aberrations and survival in ovarian carcinomas.

[Development of the Borderline Symptom List].

The categorical diagnosis of borderline personality disorder (BPD) is currently discussed as sufficiently reliable and valid. However, specific standardized instruments to measure the degree of the symptomatology are currently not available. Based on the criteria of DSM-IV, the Diagnostic Interview for Borderlines (DIB-R) and the opinion of clinical experts and borderline-patients, a self-rating scale was developed to quantify the intrapsychic strain of patients with BPD. 308 female borderline-patients scored the 99 items. Factor analyses revealed seven factors: self-image, affect regulation, autoaggression, dysthymia, social isolation, intrusions and hostility. Analyses of reliability and validity revealed promising results.
