Abstract
Cerebral folate deficiency (CFD) results in neurological alterations and a massive degeneration of the choroid/retina if left untreated, which limit the visual field and visual acuity. This article reports the case of a female patient with CFD, who developed autistic personal characteristics prior to reaching school age and first started to speak at the age of 3 years. At the age of 6 years she was presented because of unclear reduced visual acuity in the right eye. At that time mild bilateral peripheral chorioretinal atrophy was present, which subsequently became more pronounced. Additionally, a centrally emphasized chorioretinal atrophy further developed. Visual acuity of both eyes progressively deteriorated until stagnating at 0.1 at the age of 14 years. The causal assignment of the findings of the patient was not possible for many years. Choroideremia was excluded by molecular genetic testing (CHM gene with no mutations) and gyrate atrophy was ruled out by a normal ornithine level. The existence of a mitochondrial disease was almost completely excluded by exome sequencing. After the onset of further nonocular symptoms, e.g. neuromuscular disorders, electroencephalograph (EEG) alterations and autistic disorder, intensified laboratory diagnostics were performed in the treating pediatric hospital. Finally, an extremely low level of the folic acid metabolite 5‑methyltetrahydrofolate was detected in the cerebrospinal fluid (CSF) leading to the diagnosis of CFD. High-dose substitution treatment with folic acid was subsequently initiated. After excluding the presence of a pathogenic mutation of the FOLR1 gene for the cerebral folate receptor 1, a high titer blocking autoantibody against cerebral folate receptor 1 was detected as the cause.

Abstract
Abstract
Introduction
The PiA-study (Prognostic assessment in routine Application, NCT 01592825) was designed as a representative cohort of breast cancer patients to estimate the proportions of traditional and modern prognostic factors. The ASCO-recommended biomarkers uPA (urokinase-type plasminogen activator) and its inhibitor PAI-1 were used for biological risk assessment particularly for intermediate risk breast cancer patients and disease-free survival of the patients after 5 yrs of follow-up (F/U) was calculated.
Material & Methods
Between 2009 and 2011, 1,074 non-metastasized, primarily operated breast cancer patients from six centers in Germany were included. From 815 patients, fresh frozen tissue was obtained and processed for central testing uPA/PAI-1 by ELISA (FEMTELLE®, Sekisui Diagnostics GmbH). Low uPA/PAI-1 status is defined by uPA and PAI-1 concentrations below the published cut-offs, high status means one or both were higher than the corresponding cut-offs. Tumor characteristics were based on local pathology. The centers had to follow the national guidelines. In low-risk patients, adjuvant chemotherapy was spared. The median F/U is 56 months (range 0-78).
Results
In the total cohort of 1,074 patients, 166 had G1- and 237 had G3-tumors. Of the 671 patients with a G2-tumor, the following were allocated to the high-risk group: node-positive (n=371), younger than 35 yrs (n=17), and triple-negative (TN) or HER2-positive (n=118). For 253 tumors of the remaining 355 patients with an intermediate risk of recurrence (pN0, G2, HR positive, HER2-negative, ≥35 yrs), uPA/PAI-1 status was available. 126 (49.8%) were allocated to the low-risk group, one patient had a recurrence. At 5 yrs, in the total cohort 90.6% (95% CI, 89.5-91.7) of the patients were free of invasive disease. Of 114 HER2-positive tumors, 94 (82.4 %) had a high uPA/PAI-1 status, only one of the 38 HR negative/HER2 positive tumors had a low uPA/PAI-1 status. In the TN group, the majority of tumors had a high uPA/PAI-1 status (66 of 81; 81.5 %). In 30 patients lymph nodes were involved, 18.5% (n=15) had a low uPA/PAI-1 status, one event was detected. In N pos. patients with an high uPA/PAI-1 6 events were observed.
Conclusion
Testing for uPA/PAI-1 in the daily routine is feasible, fresh frozen tissue has been prepared from 76% of the tumors of the recruited patients, 37% of them had a low risk status. Using uPA/PAI-1, about half of the node-negative patients with an intermediate risk of recurrence were allocated to a group with an extremely low risk of recurrence and thus chemotherapy could be spared. Also in node-positive disease, uPA/PAI-1 has a prognostic impact.

Abstract
Abstract
Background:
ASCO Tumor Marker Guidelines 2007 recommended clinical routine use of the invasion markers uPA and PAI-1 for risk assessment in node-negative breast cancer patients (Harris et al. JCO 2007; 25:5287), and in some countries, e.g. Germany and France, risk assessment using these markers is broadly used. We wanted to evaluate the impact of uPA/PAI-1 on identifying patients with low risk of recurrence also in the daily routine in order to demonstrate that >25 years since their first description, these markers are still valuable.
Material and Methods:
We identified a cohort of 227 patients who were tested for uPA and PAI-1 in the clinical routine before 2012. Fresh frozen tissue of the primary tumor was obtained at biopsy or operation and processed for testing by a commercially available ELISA (FEMTELLE®, Sekisui Diagnostics GmbH) as previously described (Thomssen et al. JNCI 2009;101:1028). Tumor and patient characteristics were documented and all patients were regularly followed. Tumor concentrations below 3 ng/mg protein for uPA and below 14 ng/mg protein for PAI-1 were considered indicating low risk of recurrence (Harbeck et al. EJC 2013; 49:1825). Disease-free survival was defined as survival free from metastasis and loco-regional recurrence.
Results:
In our cohort, 86 patients had low tumor levels of uPA/PAI-1 (37.9 %). The median follow-up was 38.9 months (0.4 – 113.5 months). Adjuvant chemotherapy was delivered to 25 of 86 patients (29.1%) in the low risk group and to 85 of 141 patients (60.3%) in the high risk group; if steroid hormone receptor status was positive, generally adjuvant endocrine therapy for five years was advised. Using immunohistochemical subtyping, 73 of 86 patients with low uPA/PAI-1 values were luminal-like, 9 patients had a HER2-positive tumor and 3 patients had a triple negative breast cancer (TNBC). In patients with uPA or PAI-1 or both elevated, 105 of 141 patients had a luminal-like cancer, 12 patients were HER2 positive and 22 had TNBC; 1 case unknown. At 60 months of follow-up, patients with low uPA and/or PAI-1 tumor values had not experienced any recurrence, while in the high risk group 7 recurrences were observed although adequate adjuvant therapy was delivered (log-rank p=0.07). In node-negative pts with low uPA/PAI-1 values (n=72; pN0 70, cN0 2), no recurrences were observed, in 104 high risk patients 5 recurrences were observed (p=0.057).
Conclusions:
This observation confirms that also in daily routine, patients with a very low risk of recurrence can be identified by testing for uPA/PAI1. This group of pts comprises nearly 40% of pts and in these patients further evaluation with expensive predictive tests can be avoided and - above all - potentially toxic adjuvant chemotherapy can be spared.

Abstract
Abstract
Background: The urokinase-type plasminogen activator (uPA) and its inhibitor PAI-1 are validated as prognostic factors at the highest level of evidence within the node-negative group of breast cancer patients (Harris L et al., JCO 2007; 25:5287).
Usually, patients receive a core-needle biopsy before surgery. A prior feasibility study showed that the method of sampling (ex vivo from the surgical specimen using a small core needle or the larger excision specimen) doesn't influence the uPA and PAI-1 results (Thomssen et al., J Natl Cancer 2009; 101:1028). With the current study, we assessed how well uPA and PAI-1 values obtained from the core needle biopsy (in vivo) predict the expression level of these prognostic factors in the later surgical specimen.
Material and Methods: Fresh frozen material of 2–3 core needle biopsies (min 10 mg each) and the corresponding tumor material (min 50 mg) removed by subsequent surgery were collected from 110 patients in two hospitals. Only areas of the surgical specimen were selected for testing that had a sufficient distance to the needle biopsy defect. The uPA and PAI-1 concentrations were analysed using a commercially available ELISA test (FEMTELLE™; American Diagnostica, Inc., Stamford, CT). The predictive values (and sensitivity/specificity) of the core-needle biopsy data were calculated to forecast the uPA and PAI-1 values of the corresponding surgical specimen results.
Results: Sensitivity, specificity, the positive (ppv) and negative (npv) predictive values for uPA, PAI-1 and for the combination of uPA/PAI-1 are listed in table 1. Low concentrations of uPA in the core needle biopsies correlate with low concentrations in the surgical specimens across the entire study cohort as well as in the group with an intermediate (G2, N0) risk (npv = 0.91).
The clinical and pathological data of the cohort and the risk assessment will be presented.
Conclusion: Most important, low uPA/PAI-1 results in core-needle biopsies predict low results in the surgical specimen. In some cases, core-needle biopsies and surgical specimen show discordant data. These cases do not correlate with any clinical or pathological factors such as time between needling and surgery, grading, tumor size or hospital. We assume that these discordances are caused by pre-surgical manipulations, which change expression patterns in the remaining tissue as it is reported also from multi-gene tests.

Abstract
The differential diagnostic evaluation of painful functional disorders of the lumbosacral and lumbopelvic region, i. e. the so-called “low back pain” is very extensive, but is often reduced to the question of chronicity. The manual medical diagnosis can make a valuable contribution in such cases for determination of structural and functional pathology. Early application of manual medical therapies seems to be effective for peracute complaints. The mobilization of restrictions of the pelvic visceral attachments should be included. In the following review manual medical syndromes are presented that summarize the findings from the musculoskeletal and visceral system. This is intended to facilitate the primary differential diagnostic evaluation, as well as treatment planning. The combination with osteopathic methods is very profitable. A necessary specialist differential diagnosis remains essential.

Abstract
A 16- year-old boy with long-standing severe Tourette syndrome (TS) and mental retardation, non-responsive to complex pharmocological and behavioural treatment was selected for bilateral deep brain stimulation (DBS) of the globus pallidus internus (GPi). Pre-operative and post-operative Yale Tourette syndrome scale (YTSS) scores and several other scores were used to quantify the effect of DBS up to one year follow-up. Although subscores of the YTSS improved, the overall outcome of chronic GPi-DBS showed no substantial therapeutic effect. This finding is in contrast to markedly improved TS of the only two adolescent TS patients in whom DBS has been performed so far. In this article we discuss possible reasons for the poor therapeutic effect of GPi-DBS in our patient contributing to the on-going debate on DBS inclusion criteria for adolescent TS patients.

Abstract
OBJECTIVE A study was undertaken to assess the clinical value of magnetic resonance (MR) imaging-guided interventions in women with a family history, but no personal history of breast cancer. METHODS AND PATIENTS Retrospective review was performed on 63 consecutive women who had a family history, but no personal history of breast cancer. A total of 97 lesions were referred for an MR-guided intervention. Standardized MR examinations (1.0 T, T1-weighted 3D FLASH, 0.15 mmolGd-DTPA/kg body weight, prone position) were performed using a dedicated system which allows vacuum assisted breast biopsy or wire localization. RESULTS Histologic findings in 87 procedures revealed 9 (10%) invasive carcinomas, 12 (14%) ductal carcinomas in situ, 2 atypical ductal hyperplasias (2.5%) and 2 atypical lobular hyperplasias (2.5%). Sixty-two (71%) benign histologic results are verified by an MR-guided intervention, retrospective correlation of imaging and histology and by subsequent follow-up. In ten lesions the indication dropped since the enhancing lesion was no longer visible. Absent enhancement was confirmed by short-term re-imaging of the noncompressed breast and by follow-up. CONCLUSION Malignancy was found in 24%, high-risk lesions in 5% of successfully performed MR-guided biopsy procedures. A 57% of MR-detected malignancies were ductal carcinoma in situ. In 10% of the lesions the intervention was not performed, since no enhancing lesion could be reproduced at the date of anticipated intervention. Such problems may be avoided if the initial MRI is performed in the appropriate phase of the menstrual cycle and without hormonal replacement therapy.

Abstract
Information on the regulation of steroid hormone receptors and their distinct functions within the human endometrial epithelium is largely unavailable. We have immortalized human primary endometrial epithelial cells (EECs) isolated from a normal proliferative phase endometrium by stably transfecting the catalytic subunit (hTERT) of the human telomerase complex and cultured these hTERT-EECs now for over 350 population doublings. Active hTERT was detected in hTERT-EECs employing the telomerase repeat amplification assay protocol. hTERT-EECs revealed a polarized, non-invasive epithelial phenotype with apical microvilli and production of a basal lamina when grown on a three-dimensional collagen-fibroblast lattice. Employing atomic force microscopy, living hTERT-EECs were shown to produce extracellular matrix (ECM) components and ECM secretion was modified by estrogen and progesterone (P4). hTERT-EECs expressed inducible and functional endogenous estrogen receptor-alpha (ER-alpha) as demonstrated by estrogen response element reporter assays and induction of P4 receptor (PR). P4 treatment down-regulated PR expression, induced MUC-1 gene activity and resulted in increased ER-beta transcriptional activity. Gene activities of cytokines and their receptors interleukin (IL)-6, leukemia inhibitory factor (LIF), IL-11 and IL-6 receptor (IL6-R), LIF receptor and gp130 relevant to implantation revealed a 17 beta-estradiol (E2)-mediated up-regulation of IL-6 and an E2- and P4-mediated up-regulation of IL6-R in hTERT-EECs. Thus, hTERT-EECs may be regarded as a novel in vitro model to investigate the role of human EECs in steroid hormone-dependent normal physiology and pathologies, including implantation failure, endometriosis and endometrial cancer.

Abstract
OBJECTIVE The aim of this study was to investigate mechanisms of motor-cortical excitability and inhibition which may contribute to motor hyperactivity in children with attention deficit hyperactivity disorder (ADHD). METHODS Using transcranial magnetic stimulation (TMS), involvement of the motor cortex and the corpus callosum was analysed in 13 children with ADHD and 13 sex- and age-matched controls. Contralateral silent period (cSP) and transcallosally mediated ipsilateral silent period (iSP) were investigated. RESULTS Resting motor threshold (RMT), amplitudes of motor evoked potentials (MEP) and cSP were similar in both groups whereas iSP-latencies were significantly longer (p<0.05) and their duration shorter (p<0.01) in the ADHD group. For the ADHD group iSP duration tended to increase and iSP latency to decrease with age (n.s.). Conners-Scores did neither correlate with iSP-latencies and -duration nor with children's age. CONCLUSIONS The shortened duration of iSP in ADHD children could be explained by an imbalance of inhibitory and excitatory drive on the neuronal network between cortex layer III-the projection site of transcallosal motor-cortical fibers-and layer V, the origin of the pyramidal tract. The longer iSP-latencies might be the result of defective myelination of fast conducting transcallosal fibers in ADHD. iSP may be a useful supplementary diagnostic tool to discriminate between ADHD and normal children.

Abstract
The aim of this study was to retrospectively examine whether the occurrence of squamous cell carcinoma (SCC) antigen tumour marker in the serum has prognostic significance in operable SCC of the cervix at the International Federation of Gynaecology and Obstetrics (FIGO) stages IA2-IIB. A total of 129 patients who had undergone a radical hysterectomy for SCC of the uterine cervix at the Department of Gynecology of the Martin-Luther University, Halle-Wittenberg in 1991-2000 were included. SCC antigen (Ag) was measured by IMx SCC-Ag microparticle enzyme immunoassay (Abbott Laboratories, Abbott Park, IL, USA). To assess the prognostic value of SCC antigen in the serum, we used a step-by-step multivariate analysis based on the Cox proportional hazard regression model. Using a cut-off value of 3.0 ng/ml, we detected preoperative SCC antigen in the serum as an independent prognostic factor in SCC of the cervix, both for recurrence-free and overall survival (P=0.003 and 0.0078). In this retrospective analysis the value of the SCC antigen tumour marker correlates with prognosis in operable SCC of the cervix, independent of tumour size, pelvic nodal status, cervical stroma infiltration, parametrial spread and tumour grading.

Abstract
Despite definite indication for psychopharmacologic intervention, severe and persistent symptoms of aggressive and self-injurious behaviour still remain a therapeutic challenge. As recent research has demonstrated, not only the dopaminergic and serotonergic but also the endogenous opiate system plays a role in the pathogenesis of self-injurious behaviour. Nevertheless, the efficacy of classical neuroleptics as well as opiate antagonists is questioned. In open and controlled studies, the administration of the atypical neuroleptic risperidone (a serotonin 2A-dopamine D2 antagonist) was associated with a long-term effect in reducing self-injuries. In our clinical trial, 20 mentally retarded adults presenting with severe self-injurious and aggressive behaviour were administered risperidone over a follow-up period of 35 months. Clinical efficacy was measured with the Disability Assessment Schedule (DAS), conducted in a home for people with mental retardation. In 17 patients, a significant reduction in self-injurious behaviour is shown. Besides, there was a significant overall clinical improvement in behaviour.

Abstract
Based on the efforts by the legislator to standardize the law for disabled persons and to simplify the accesses to appropriate assistance, procedures of expert reports are exemplarily presented from the aspect of child and adolescent psychiatry. Obliged to the principle of the two aspects for constituting a claim (which is first to set up a diagnosis and then to evaluate the existent or imminent handicap, both serving as the basis for the claim), etiological models, diagnostic - including developmental psychological - and therapeutic approaches in underlying psychiatric disorders of learning difficulties such as attention deficit hyperactivity disorders, pervasive developmental disorders, specific developmental disorders in learning abilities, and mental retardation are described as the participation in social life is either at risk or already affected. With regard these descriptions it is readily recognizable that child and adolescent neuropsychiatry has not only to provide professional competence in cases of appraisal question formulations concerning special assistance in early childhood, determination of special educational needs, and creation of plans for auxilliary interventions, but should also be employed regularly.

Abstract
The aim of this study was to determine the diagnostic accuracy and feasibility of sentinel lymph node (SLN) detection using a gamma probe in patients with Figo IB cervical cancer. Between January 1999 and September 2000, 14 patients with cervical cancer, planned for radical hysterectomy were eligible for the study. The day before radical hysterectomy we injected technetium(99)m-labelled nanocolloid in each quadrant of the cervix. Dynamic and static images were recorded using a gamma camera. SLNs were identified intraoperatively using a handheld gamma-detection probe. After resection of SLNs a standard radical hysterectomy with pelvic lymph node dissection was performed. Patients and tumour characteristics were compared with sentinel node detection and with final histopathological and immunohistochemical results. Scintigraphy showed focal uptake in 13 of the 14 patients. Intraoperatively we detected 26 sentinel nodes by gamma probe. In 8 of 13 patients, one or more sentinel nodes were identified unilaterally, in 5 women bilaterally. Histologically positive SLNs were found in only 1 patient. We did not find any false-negative SLN in our series. In conclusion identification of sentinel nodes in cervical cancer is feasible with preoperatively administered technetium(99)m-labelled nanocolloid.

Abstract
In a study, a radiofrequency (RF) treatment was performed on a patient with a small breast cancer after vacuum biopsy. As usual in cases with a malignant diagnosis, surgical excision and axillary dissection followed. Histopathology revealed some residual tumor in the margin of the cavity. It could not be distinguished from vital tumor on the hematotoxylin eosin (HE) stain. Based on the correlation of MRI and histopathology after subsequent surgical excision, we did, however, presume that the residual was contained within the zone of inactivation. Thus the hypothesis arose that, if too high temperatures can be avoided, it might be possible to inactivate tumor cells without significantly impairing histopathologic assessment. This hypothesis was supported by the following in vitro experiment performed on a fresh specimen: An RF treatment was performed using temperatures up to 70 degrees C only. Half of the specimen underwent HE-staining, the other half vitality testing. The results indicate that if a given temperature range is strictly observed it appears possible to inactivate tissue before tissue sampling, since histopathologic diagnosis will not be impaired. Further technologic improvements may eventually allow to develop a pre-treatment method which might permit to avoid potential hematogenous tumor spread during subsequent biopsy.

Abstract
We have studied the cellular localization of the relaxin-like factor (RLF) in the histologically normal cyclic endometrium collected from days 3--26 of the menstrual cycle. RLF transcripts and protein were detected in the luminal and glandular epithelium and in stromal cells at all stages of the cyclic endometrium. Increased expression of RLF was observed in endometrial tissues in the proliferative as compared to the secretory phase, suggesting that oestrogens affect RLF gene activity in the human endometrium. The cellular localization of RLF transcripts and protein was also determined in first trimester placental tissues obtained from normal and ectopic tubal implantation sites and in third trimester placentae of normal and pre-eclamptic pregnancies. In first trimester placenta, weaker expression of RLF was observed in the syncytiotrophoblast as compared to the underlying cytotrophoblast. Extravillous trophoblast cells constitutively expressed RLF. Trophoblast cells were the main source of RLF in the human placenta and trophoblastic RLF gene activity was unaffected by either the site of implantation or the invasive properties of the cytotrophoblast as demonstrated by samples from patients with tubal implantation and pre-eclampsia respectively. Decidual cells weakly expressed RLF. The presence of unprocessed and cleaved immunoreactive RLF in term placenta was determined by Western analysis. The above results suggest a functional role for both RLF isoforms within normal placental tissue.

Abstract
Sertoli-Leydig cell tumors belong to the group of sex-cord stromal tumors of the ovary. They account for less than 0,5% of all ovarian neoplasms. The majority of these tumors are benign, and almost all are localised unilaterally. Herewith, we describe an ovarian Sertoli-Leydig cell tumor in an 11-year-old girl. Serum levels of estradiol and progesterone were mildly elevated. while testosterone and androstendion levels were raised to around three- and sevenfold upper normal limit respectively on presentation. A left salpingo-oophorectomy was performed. Microscopically, the tumor was intermediately differentiated. At 6 months follow-up, there was neither clinical nor sonographical evidence of recurrence, and almost all sex hormone levels had returned to within normal range. Treatment of this pathological entity has to be individualized according to patient age, stage of tumor and degree of differentiation.

Abstract
PURPOSE This retrospective study was undertaken to investigate the morphologic and dynamic features of in situ and minimally invasive breast cancer on contrast-enhanced (c.-e.) MR imaging and to examine possible associations to pathology features. MATERIAL AND METHODS A total of 71 patients underwent MR imaging. T1-weighted FLASH-3D images were obtained before and after intravenous administration of Gd-DTPA. Histopathologic analysis of 78 lesions revealed ductal carcinoma in situ (DCIS) n = 50 and DCIS with microinvasion n = 28. MR features were correlated with histopathologic findings. RESULTS Enhancement in DCIS was focal (73%), diffuse (10%) or ductal (17%). No enhancement occurred in two cases (4%). In 65% enhancement speed was classified as delayed. There was a tendency toward a more ill-defined (83 vs. 43%) enhancement pattern in high grade DCIS and a more ductal (29 vs. 12%) and faster (50 vs. 29%) enhancement in comedo type DCIS. However, significant differences in the enhancement behaviour could neither be demonstrated between high grade and non high grade DCIS nor between comedo and non comedo type DCIS. No significant differences were noted between pure and microinvasive DCIS. CONCLUSION In this retrospective analysis the majority (96%) of DCIS lesions show contrast enhancement. However, in only about 50% of DCIS the criteria of a so-called 'typical' enhancement behaviour was fulfilled, that means strong, early, focal ill-circumscribed or ductal. Enhancement that follows a duct is often associated with malignancy, however this feature was only present in 17% of the cases. c.-e. MR imaging allowed the detection of 25 additional foci of DCIS. Therefore malignant in situ lesions can be present with atypical enhancement, and should be taken into consideration in high-risk patients in particular.

Abstract
OBJECTIVE Up to now, the mechanisms responsible for progression from noninvasive to invasive breast cancer have remained obscure. Tenascin is an extracellular matrix glycoprotein, present in embryonal and fetal tissues, which is also found in the stroma of various benign and malignant pathologies. We studied the expression and immunohistochemical behavior of tenascin in specimens of invasive and preinvasive breast cancer in order to assess its potential role as a marker for tumor invasion. MATERIALS AND METHODS Sixty-eight specimens including 29 noninvasive ductal cancers, 12 invasive ductal cancers, 5 adenoses, 7 fibroadenomas, and 15 samples of normal human breast tissue were evaluated. An immunofluorescent microscopic technique was used for analysis of the localization and distribution of tenascin. Paraffin-embedded biopsies were incubated with primary monoclonal anti-tenascin antibodies (1:25, Dako-tenascin, TN2). Subsequently, trimethylrhodamine-isothiocyanate-conjugated secondary antibodies (rabbit anti-mouse immunglobulins (Dakopatts, Denmark) were added to visualize the protein. RESULTS A significant tenascin expression was observed around the ducts in all samples of patients with preinvasive breast cancers. Intensive staining was also found in the periductal stroma of all specimens of patients with invasive breast cancers. Benign breast lesions showed weaker reactivity. No tenascin expression was detectable in normal human breasts, while tissue samples of in situ cancers presented variable staining intensities positively correlating with the degree of differentiation. CONCLUSION Tenascin immunofluorescence may prove a suitable and helpful adjunct for diagnosing malignant disease and for predicting the invasive potential of premalignant breast lesions.
