Introduction: Polypoid endometriosis is a rare variant of endometriosis characterized by histological features resembling an endometrial polyp. Lesions frequently affect the ovaries presenting as adnexal masses which may mimic malignancy, with an extremely complex differential diagnosis due to the poor evidence reported in Literature. Case description: In this report, we describe the case of a 43 years old woman referred to pelvic transvaginal ultrasound examination for recurrent abdominal pain, in whom sonography revealed a pelvic mass with features highly suspicious for ovarian carcinoma. Surgical removal allowed histopathological diagnosis of polypoid endometriosis, with no signs of malignancy. At ultrasound examination, the lesion appeared as a multilocular-solid mass, with low-level echogenicity of cystic content, multiple papillary projections, and solid areas with high vascularization and apparent infiltration of the uterus. At retrospective review of the sonographic images after pathological examination, some features mirroring the histological architecture of polypoid endometriosis could be identified in the solid components of the mass: these included the hyperechoic appearance, the rounded outline of the intracystic projections, and the vascularization pattern with a single central vessel with branching. Conclusions: To date, this is the first work providing a detailed ultrasonographic description of polypoid endometriosis using shared terms and definitions and relating these findings with available evidence about radiologic and histopathologic features. The report shows how this condition could strongly mimick ovarian malignancy, though several sonographic features can be identified reflecting the histopathological patterns of those lesions.

Primary ovarian carcinoids are very rare tumors that belong to the germ cell family of ovarian malignancies. They account for less than 1% of all carcinoid tumors and for less than 0.1% of all ovarian neoplasms. Recurrences are even rarer, with only few cases reported in the literature. Strumal carcinoid has recently been recognized as an extremely rare distinct entity. We report on a patient with bilateral mature cystic teratoma with millimetric foci of ovarian strumal carcinoid who developed lymph node para aortic metastasis after 30 years from primary diagnosis. Our case is thus far the second report of a metastatic strumal carcinoid and the first one in which strumal carcinoid occurred bilaterally and was also metastatic.

Objectives To report the effects on the urinary function of ospemifene prescribed for vulvovaginal atrophy (VVA) in patients with overactive bladder (OAB) symptoms refractory to the first line of pharmacologic treatment with antimuscarinic or β3-agonists drugs. We also try to identify any predictors of response to the ospemifene treatment. Study design Twenty-five patients with OAB confirmed by detrusor overactivity at urodynamics, refractory to first-line therapy for OAB, were enrolled for the study. All of them received ospemifene 60 mg for 12 weeks because of concomitant VVA. We performed a clinical examination, a 3-day voiding diary, ultrasound examination of bladder wall thickness (BWT), and evaluation by Visual Analogic Scale (VAS) of vaginal dryness at baseline and at 12 weeks. We evaluated urinary symptoms and their impact on the quality of life with UDI-6 SF and OAB-Q (Qol, sf) questionnaires. Results After 12 weeks of treatment, we observed a significant reduction in the daily (24 h) numbers of episodes of micturition, of nocturia, of urgency and of incontinence. We also found a significant reduction in BWT and vaginal dryness, together with an improvement of OAB-Q and UDI6 SF scores. Among patients who subjectively benefited from the treatment, we found a baseline lower prevalence of constipation and a higher degree of vaginal dryness. Conclusions Ospemifene might be a useful option for postmenopausal women with VVA and OAB symptoms, refractory to the first line of treatment with β3-agonists or antimuscarinic drugs, before considering invasive options.

Objectives To investigate the role and feasibility of sentinel lymph node biopsy (SLNB) in breast cancer patients with a local recurrence and no clinically positive axillary lymph nodes. Materials and Methods A total of 71 patients underwent SLNB for breast cancer recurrence. At first surgery, they had received SLNB (46.5%), axillary lymph node dissection (ALND) (36.6%) or no axillary surgery (16.9%). Results Lymphatic migration was successful in 53 out of 71 patients (74.6%) and was significantly higher in patients with previous SLNB or no axillary surgery than in those with previous ALND (87.9% vs. 53.8%; p = 0.009). Aberrant lymphatic migration pathways were observed in 7 patients (13.2%). The surgical SLNB was successfully performed in 51 patients (71.8%). In 46 patients (90.2%) the SLN was histologically negative, in 3 patients (5.9%) micrometastastatic and in 2 patients (3.9%) macrometastatic. The 2 patients with a macrometastates in SLN underwent ALND, In 4 out of the 18 patients with failure of tracer migration ALND, performed as surgeon’s choice, did not find any metastatic node. After a median follow-up period of 39 months (range: 2–182 months), no axillary recurrence has been diagnosed. Conclusion A SLNB in patients with locally recurrent breast cancer, no previous ALND and negative axillary lymph nodes is technically feasible and impacts on the ALND rate. In patients who at primary surgery received ALND, migration rate is significantly lower, aberrant migration is frequent and no clinically useful information has been obtained.

Objectives The association between pelvic organ prolapse (POP) and stress urinary incontinence (SUI) is very common. When POP surgery is indicated and the patient has concomitant SUI, there are two treatment strategies: the one-step strategy (concomitant correction of POP and SUI) and the two-step strategy (correction of POP with subsequent evaluation of SUI). Guidelines from the International Continence Society and International Consultation on Incontinence recommend that a urodynamic assessment (UA) should be performed before surgery as this can reveal the presence of urodynamic SUI, but the role of UA is the subject of debate as it does not seem to improve treatment decisions. The aim of this study was to identify the presence of pre-operative urodynamic parameters that were predictive of POSUI, and to identify patients who could benefit from concomitant correction of SUI during POP surgery Study design A retrospective evaluation was undertaken of 155 patients with at least second-degree POP who underwent POP surgery after UA between 2009 and 2016 in an Italian gynaecology and obstetrics department. Of these, 61 patients were clinically incontinent before surgery and 94 patients were clinically continent. After UA, patients were stratified using a maximum urethral closure pressure (MUCP) cut-off of 50 cmH2O; the risk of POSUI was calculated using this value. Results POP surgery alone resolved SUI in 60 % of the 61 clinically incontinent patients; only 30 % of these patients had urodynamic SUI and >50 % did not have POSUI. Thirty-six percent of the 94 continent patients had occult SUI on UA and 16 % developed de-novo POSUI. Seventy-five percent of all patients with occult SUI did not develop de-novo SUI. MUCP was lower in patients with POSUI than in patients without POSUI (p=0.013). The probability of POSUI was higher in patients with MUCP ≤50 cmH2O. The number needed to treat (NNT) to prevent one case of POSUI in these patients was 2, compared with an NNT of 4 in the continent group. Eight percent of patients underwent further surgery for SUI. Conclusions Clinically incontinent patients with MUCP ≤50 cmH2O will gain the greatest benefit from concomitant POP and SUI surgery. However, concomitant surgery has more severe adverse events. Given that 62.3 % of patients resolved SUI after POP surgery alone, it is important not to overtreat these women. Clinical pre-operative SUI is the best indicator of POSUI and was found to increase the risk of POSUI (odds ratio 3.2, 95 % confidence interval 1.5–6.8; p=0.003). Despite the small sample size, the two-step strategy appears to result in lower use of mid-urethral slings and a clear reduction in complications. It is important not to focus on the diagnosis of urodynamic SUI in continent patients but to evaluate MUCP carefully.

Objectives Defects in female pelvic organ support are highly prevalent. Uterosacral ligament suspension at the time of primary prolapse repair (McCall culdoplasty) is a well-established surgical option to prevent prolapse recurrences. Recently Shull's high uterosacral ligament suspension technique has gained increasing popularity among Uro-Gynaecologists. A study carried out in 2017 by Spelzini et al. compared these two techniques, showing proper safety and efficacy in the treatment of prolapse, with no statistically significant differences as to operative time, complication rate, anatomical, functional and subjective outcomes [ 1 ]. Our study aims at comparing the effectiveness, complication rate, recurrence rate, quality of life and functional result of the two techniques. Study design This is a retrospective study carried out on 224 patients who underwent vaginal cuff suspension for pelvic organ prolapse. Cases were extracted from hospital medical records of all women managed with surgical prolapse repair at our Gynaecology and Obstetrics department between January 2013 and February 2017. Shull suspension (group A) or McCall culdoplasty (group B) were performed according to surgeon's familiarity with the two suspension techniques. Results A total of 224 patients (69 in group A and 155 in group B) underwent surgical cuff suspension. Median operating time was 88 min for both techniques and ureteral injuries were very rare in both group A and B (1 and 0 respectively). In the evaluation of postoperative questionnaires, no statistically significant differences were found, except for "Urinary Impact Questionnaire" (UIQ), which showed significantly less urinary subjective symptoms in group A. Median follow up was 13 months in group A and 15 months in group B. Post-operative Pop-Q items analysis revealed only a higher Aa point in group A at 12 months follow up visit. Objective vaginal cuff recurrence was observed in 1 patient (1,4%) in group A and 4 patients in group B (2,6%) with no statistically significant difference between the two groups. Conclusions Both uterosacral ligament suspension procedures are safe and highly effective. There were no statistically significant differences concerning surgical data, complication rates, and the majority of anatomical, functional and subjective outcomes between Shull suspension and McCall culdoplasty.

e23546 Background: Although sarcomas may arise in any site of the body, the intrinsic challenge of BS is to affect the female most frequent cancer site with a completely different and rare set of heterogeneous tumors. Unfortunately, we lack BS-specific prospective trials to precisely guide the clinical decision-making and BS patients are often sent to sarcoma referral centers only after surgery without upfront BS MTB evaluation. Recent evidences reported a significant prognosis improvement with upfront MTB evaluation in retroperitoneal or extremity sarcomas, but whether this strategy might benefit also BS is still not defined. We retrospectively evaluated our prospectively collected database to test whether an upfront MTB evaluation at BS referral centers might impact prognosis and/or the need of subsequent surgeries. Methods: Detailed information on primary surgery, diagnosis, and ≥2 years of follow-up for non-recurring patients were required. We tested the following outcomes: event-free survival (EFS), local EFS (LEFS), distant metastases EFS (DMEFS), overall survival (OS), margin status, subsequent surgeries rate. We evaluated the different outcomes according to upfront MTB evaluation. Kaplan-Meier method was used for survival analyses. Comparisons used hazard ratios (HR). Results: We included 93 patients treated between 1/2000 and 10/2019 at 2 reference BS Centers, median age 53 years (IQR 41-70), ECOG (0;1;2) 67:16:10, high/low grade 60:33. Histotypes were: malignant phyllodes tumor 42 (45%), angiosarcoma 26 (28%), other STS 25 (27%). 27 (29%) cases were considered radiation-induced with a median time from RT of 105 months (IQR 70-127). 44 patients (47%) were discussed upfront in BS MTB, whereas 49 (53%) were not. With a median follow up of 43 months, 5-year EFS, LEFS, DMEFS, and OS for the whole population were 54%, 64%, 60%, and 62%, respectively. LEFS at 5 years had a strong association with margin status (R0 74%; R1 55%, R2 0%, p < 0.001). Regardless of histology, upfront MTB was associated with a significant lower rate of subsequent surgeries (OR 0.16, 0.06-0.41), and with better EFS, LEFS, DMEFS, and OS (HRs 0.57, 0.54, 0.63, and 0.43, respectively). Conclusions: Though retrospective, this series is one of the largest reported to date in BS. Our results highlight the need for early inter-tumor board sharing of BS to take into account sarcoma specificity in the overall disease planning. Given BS rarity, these data will hardly ever be verified in a prospective fashion. Therefore, validation of these results in the Italian Sarcoma Group database is planned.

Selective serotonin reuptake inhibitors (SSRI) and serotonin-norepinephrine reuptake inhibitors (SNRI) might be an effective treatment for hot flushes (HFs) in breast cancer survivors (BCSs). This study aims to compare the efficacy and tolerability of duloxetine (SNRI) versus escitalopram (SSRI) in reducing frequency and severity of HFs in BCSs and to assess the effect on depression. Thirty-four symptomatic BCSs with emotional impairment received randomly duloxetine 60 mg daily or escitalopram 20 mg daily for 12 weeks. Patients were asked to record in a diary HF frequency and severity at baseline and after 4 and 12 weeks of treatment. Depression was evaluated through validated questionnaires (Beck Depression Inventory and Montgomery Asberg Depression Rating Scale) at baseline and after 4 and 12 weeks of treatment. Both drugs showed a significant reduction of HF frequency and severity after 12 weeks of treatment with no significant difference between the two groups. A significant improvement in depression symptoms was observed at the end of the study period within both the groups, without difference between the two drugs. In conclusion, escitalopram and duloxetine are both effective treatment for the relief of HFs in BCSs, with similar beneficial effect. A significant improvement of depression was obtained with no major side effects.

A growing body of evidence support the association between the use of hormone replacement therapy (HRT) and a higher risk of both invasive lobular carcinoma (ILC) and invasive ductal–lobular mixed carcinoma (IDLC). Overall biological and clinical features of ILC entail a more cautious diagnostic and therapeutic approach as compared with invasive ductal carcinoma (IDC). ILCs are more frequently multifocal, multicentric and/or bilateral. Mammography and ultrasound show, therefore, significant limitations, while the higher sensitivity of magnetic resonance imaging in the detection of multifocal and/or multicentric lesions seems to improve the accuracy of preoperative staging of ILCs. Early diagnosis is even more challenging because the difficult in the localization and the sparse cellularity of lobular tumours may determine a false negative core biopsy. ILC is characterized by low proliferative activity, C-ErbB-2 negativity, bcl-2 positivity, p53 and VEGF negativity, oestrogen and progesterone positive receptors, low grade and low likelihood of lymphatic-vascular invasion. However, this more favourable biological behaviour does not reflect into a better disease-free and overall survival as compared with IDC. Since lobular histology is associated with a higher risk of positive margins, mastectomy is often preferred to breast conservative surgery. Moreover, only few patients with ILC achieve a pathologic response to preoperative chemotherapy and, therefore, in most patients mastectomy can be regarded as the safer surgical treatment. The preoperative staging and the follow-up of patients with ILC are also complicated by the particular metastatic pattern of such histotype. In fact, metastases are more frequently distributed to the gastrointestinal tract, peritoneum/retroperitoneum and gynaecological organs than in IDC.

Breast cancer survivors (BCSs) often suffer from menopausal symptoms induced by systemic treatments, with a consequent negative effect on quality of life. Since the introduction of aromatase inhibitors as the standard therapy for hormone-dependent tumors, genitourinary syndrome of menopause (GSM) has become a main problem for BCSs. This new terminology refers to the wide range of vaginal and urinary symptoms related to menopause, which can be relieved by estrogen therapy. Unfortunately, systemic hormone therapy is contraindicated for BCSs and also vaginal estrogens at standard dosage might influence the risk of recurrence because they cause a significant increase of circulating estrogens. Nonhormonal vaginal moisturizers or lubricants are the first choice for BCSs but only have limited and short-term efficacy. New strategies of management of GSM are now available, including: (1) low-dose or ultra low-dose vaginal estrogens; (2) oral selective estrogen receptor modulators (ospemifene); (3) androgen therapy; (4) physical treatment with vaginal laser; and (5) psychosocial interventions. In this review we discuss and analyze these different options.

The demand for hormone replacement therapy (HRT) by women who enter the menopause is rapidly increasing in all developed countries. The concern that HRT may enhance morbidity and mortality from malignant diseases still limits the widespread adoption of hormonal treatments. Overall, epidemiological data on cancer incidence and HRT are reassuring, although long-term or inappropriate therapies may slightly increase the risk of developing malignant diseases. Many commercial hormonal compounds are currently available and the safest HRT regimen with regard to cancer risk must be identified. It is equally important that the best strategies for breast and endometrial surveillance in women commencing HRT be outlined, bearing in mind that the diffusion of hormonal therapies may be halted by unnecessary medical interventions.

Objective: To quantify pepsinogen C (PEPC) and prostaglandin D synthase (PGDS) in breast cyst fluid and examine if these two parameters can be used for breast cyst type classification. Design and Methods: We quantified PEPC and PGDS in 92 and 50 breast cyst fluids, respectively, using previously established immunofluorometric procedures. We then examined if the levels of PEPC or PGDS correlate with the type of cyst or with other clinicopathological variables. Results: Quantitative analysis of the breast cyst fluids indicated that PEPC is present in all cyst fluids at various concentrations ranging from 3 to 31,000 ng/mL. PGDS positivity was confined to 30% of the cyst fluids. PEPC and PGDS levels were correlated with the breast cyst fluid cation ratio and were associated with the type of the cyst. Increased PEPC levels in breast cyst fluids were significantly correlated with a ≥ 1.5 K + /Na + ratio and were associated with the secretory/apocrine type of cyst (Type I) ( p = 0.011). Immunoreactive PGDS levels were highly correlated with a low cation ratio and were associated with the transudative/flattened type of breast cyst (Type II) ( p = 0.0003). A weak association was observed between PEPC levels in breast cyst fluid and menopausal status ( p = 0.093). No significant associations were observed for either PEPC or PGDS concentration in breast cyst fluid and number of cysts, recurrence of the disease, family history of breast cancer, number of children, abortion, and breast feeding. Conclusions: Quantification of PEPC and PGDS in breast cyst fluid may be useful in the subclassification of cyst type in patients with gross cystic disease.

Type I hyperprolinemia (HPI) is an autosomal recessive disorder caused by proline oxidase deficiency. This enzyme is encoded by the proline dehydrogenase (PRODH) gene on 22q11. The functional consequences of different PRODH mutations on proline oxidase activity have been characterized in vitro. Few patients with HPI with epilepsy and cognitive/behavioral disturbances have been described so far. We screened four Italian children with HPI presenting epilepsy, mental retardation, and behavioral disorders for PRODH gene mutations, and attempted a genotype-phenotype correlation.

Purpose of the study A retrospective analysis on 1407 patients with invasive ductal carcinoma (IDC) and 243 invasive lobular carcinoma (ILC) was performed in order to compare the histological features, the immunohistochemical characteristics, the surgical treatment and the clinical outcome in the two groups. Results ILC seems to be more likely multifocal, estrogen receptor positive, HER-2 negative and to have a lower proliferative index compared to IDC. ILC, when treated with conservative surgery, required more frequently re-excision and/or mastectomy because of positive resection margins. No difference was observed in terms of 5-year disease free survival and local relapse free survival between the two groups, in the whole series and in the subgroup of patients treated with breast-conserving treatment. Conclusion ILC can be safely treated with conservative surgery but a more accurate preoperative evaluation of tumor size and multifocality could be advocated, in order to reduce the re-excision rate.

A small subset of breast and ovarian cancers is related to the mutation of dominant susceptibility genes. The recent isolation of BRCA1 and BRCA2 has created great interest and expectations among members of families with a positive history for breast/ovarian cancer. We reviewed the literature to explore the clinical implications of genetic testing for BRCA1 and BRCA2 mutations among high risk women. Both the value of the information provided by the test and the efficacy of the preventive and diagnostic measures presently available have been examined. We also specifically address the issue of ethical dilemmas arising from widespread availability of genetic information, including psycological reactions of those who receive the test, genetic discrimination by health insurance companies or employers and prenatal testing for BRCA1 mutations.

The recombinant monoclonal antibody trastuzumab has antiproliferative effect on breast cancer (BC) cells with ErbB2 overexpression. We postulated that a mechanism able to modify ErbB2 expression enhances the antitumor effect of trastuzumab. We analyzed whether granulocyte-colony stimulating factor (G-CSF), widely used in adjuvant cancer therapy to alleviate chemotherapy-induced myelotoxicity, could influence ErbB2 expression in BC cells and patients. The expression of ErbB2 (Herceptest) was analyzed in four BC cell lines (BT474, SKBR3, ZR75.1, and T47D) treated with G-CSF and in five samples biopsies from BC patients subjected to G-CSF rescue after chemotherapy. The effects of G-CSF and trastuzumab alone or their combination on cell growth and apoptosis were investigated. G-CSF receptor was detected on all cell lines and BC patients. G-CSF induced upregulation of ErbB2 in SKBR3, ZR75, and T47D cells. This modulation was not associated with an increase in tumor cell growth in vitro. Trastuzumab alone inhibited colony formation in soft agar but did not induce apoptosis on BC cells with no or low ErbB2 genomic amplification. The combination of trastuzumab and G-CSF enhanced the inhibition of tumor colony formation and induced apoptosis on these cells. This effect was further increased by G-CSF pretreatment. Five of nine BC patients showed an increase of Herceptest score after G-CSF administration. G-CSF treatment increases ErbB2 expression in vitro and in vivo enhancing the activity of trastuzumab on BC cell lines inducing apoptosis of BC cells with low or no ErbB2 genomic amplification.

MTHFR gene variants C677T and A1298C seem to be related to an increased risk of migraine. Folates' metabolism could play a role in the pathophysiology of migraine. We supplemented 16 children with migraine, hyperhomocysteinemia, and MTHFR polymorphisms with folic acid and obtained a resolution/reduction of migraine attacks. Although the mechanism leading to these effects has been not made clear, we believe that the use of folic acid needs further investigations in migraineurs with hyperhomocysteinemia and MTHFR variants. A randomized, double-blind, placebo controlled crossover trial is needed to support these findings.

Epidemiologie studies have attempted to identify whether certain subgroups of postmenopausal women using hormone replacement therapy (HRT) are more susceptible to the effects of steroids in relation to breast cancer risk. Subgroups of interest include women with a family history of breast cancer, women with a history of benign breast disease (BBD), obese individuals, older hormone users, past users of oral contraceptives (OC), and women who consume alcohol.

Aim of the study: To assess whether the pathological characteristics of breast carcinomas arising in post-menopausal women who ever used hormonal replacement therapy (HRT) differ from those of post-menopausal patients who never used HRT. Materials and methods: Six hundred and forty three consecutive breast cancer patients were entered in a case control-study. Cases were represented by 111 breast cancer patients who had used or were using HRT at the time of diagnosis, while the remaining 532 patients who never used HRT were chosen as controls. Results: Tumour diameter was smaller in HRT users (17.6 vs 22.1 mm; pZ0.002) and tumours of lobular histology were almost twice more frequent among HRT users as in 'never users' (21 vs 12%; pZ0.01). No differences were found in grading, hormonal receptor status and axillary nodal status. The expression of c-erb B-2, p53, Ki67 e PS2 measured by immunohistochemistry was similar in the two groups. Conclusions: Our findings suggest that HRT use may modify the pathological presentation of breast cancer. Further studies are indicated, while other clinical- pathological characteristics did not differ according to HRT use. Q 2005 Published by Elsevier Ltd.

During the menopause, levels of SHBG, IGF-I and IGFBPs are significantly modified by the use of different HRT regimens. Objective: The aim of this study is to evaluate the influence of three different HRT regimens on serum levels of SHBG, IGF-I, IGFBP-1 and IGFBP-3 in postmenopausal women. Methods: 41 postmenopausal women requesting HRT were enrolled in the study. Subjects were divided in three groups according to the therapy assigned; Group A: estradiol 2 mg/day+cyproterone acetate 1 mg/day in a cyclic sequential regimen; Group B: estradiol hemihydrate 2 mg/day plus norethisterone acetate (NETA) 1 mg/day in a continuous combined regimen; Group C: estradiol hemihydrate 1 mg/day plus NETA 0.5 mg/day in a continuous combined regimen. Blood samples were drawn before the start of hormonal treatment and after 6 months of HRT. Levels of SHBG, IGF-I, IGFBP-1 and IGFBP-3 in the serum were measured by means of a specific immunoassay. Results: In group A, a significant increase of SHBG, no change of IGFBPs and a significant decrease of IGF-I were observed; in group B and in group C, no significant variations for any of the parameters were recorded. Conclusions: The association of cyproterone acetate to oral estradiol determines a significant reduction of IGF-I levels and an increase of SHBG; nevertheless, it does not seem to influence the serum levels of the IGF-I binding proteins. The treatment with oral continuous combined estrogens plus androgenic progestins, at low doses, produces minor, not significant, changes in the circulating levels of IGF-I, SHBG and IGFBPs.

We have analyzed matched serum and breast cyst fluid samples for total PSA from 148 patients with fibrocystic breast disease. We have also determined the molecular forms of PSA (free PSA and PSA bound to α(1)‐antichymotrypsin) in 78 breast cyst fluid samples. We found that total PSA can be detected in all cyst fluids and in about 75% of female sera. The median total PSA concentration in breast cyst fluid (bcf) is about 30 times higher than the median in the corresponding sera. Breast cyst fluid and serum PSA are not correlated with each other. Total serum PSA is inversely associated with patient age but the inverse association between bcf PSA and age is weak. Lower total PSA in bcf was seen in women who breast feed, and higher bcf PSA is associated with multiple cysts. Type I cysts (with a high K(+)/Na(+) ratio) tend to have higher total PSA than Type II cysts. All but three of the fractionated cyst fluids (75/78; 96%) had free PSA as the predominant molecular form. The most consistent finding of our study was the positive association between the cyst fluid K(+)/Na(+) ratio and the free to bound PSA ratio. This association was confirmed by Spearman correlation as well as by Wilcoxon and chi‐square analysis. Secretory/apocrine cysts (Type I) tend to have more total PSA and proportionally more free PSA than transudative/flattened cysts (Type II). J. Clin. Lab.

During November 1993 to December 1994 researchers in Italy interviewed 300 women under 46 years of age with histologically proven breast cancer (registered at the Oncological Hospital M. Ascoli the Civic Hospital of Palermo and the gynecological oncology department of the University of Turin) and 300 women with acute diseases but no breast cancer living in the same geographic area as the cases. They aimed to examine the relationship between use of oral contraceptives (OCs) and breast cancer risk. Cases were more likely to have a family history of breast cancer than controls (age-adjusted odds ratio [OR] = 2.34; p = .02). Only 7% of all OC users used OCs longer than 5 years. 17% used OCs for no more than 1 year. Overall OC use was not associated with an increase in breast cancer risk. When the researchers restricted the analysis to each center OC use was still not associated with this risk. The variables examined included OC use length of OC use age at first OC use OC use before first full-term pregnancy and time from last OC use. These findings show that among all the variables analyzed only family history of breast cancer was a risk factor for breast cancer.

Long-term hormone replacement therapy (HRT) is being used not only for relief of immediate disturbances which arise during menopause, but also for the prevention of osteoporosis and cardiovascular disease. The most serious concern about the use of HRT in menopause has been centered on potential oncologic risk; in particular, endometrial and breast cancer have been etiologically linked to the action of steroid hormones.

Raloxifene is a selective oestrogen receptor modulator (SERM) that has anti-oestrogenic effects on breast and endometrial tissue and oestrogenic actions on bone, lipid metabolism and blood clotting. In postmenopausal women raloxifene decreases bone turnover and increases bone mineral density, reducing the incidence of vertebral fractures. Unlike tamoxifen, raloxifene does not cause endometrial hyperplasia or cancer, as demonstrated by endometrial monitoring with ultrasonography and biopsy during treatment. Evidence suggests that raloxifene lowers total low-density lipoprotein cholesterol levels behaving like oestrogens, but does not increase high-density lipoprotein cholesterol levels. In randomised clinical trials on postmenopausal women with osteoporosis, raloxifene reduced the risk of newly diagnosed ER-positive invasive breast cancer by 76% during a median of 40 months of treatment. However, raloxifene does not alleviate early menopausal symptoms, such as hot flushes and urogenital atrophy, and may even exacerbate some of them. In conclusion, raloxifene may be an alternative for the prevention of long-term effects of oestrogen deficiency (osteoporosis and heart diseases) in women with previous breast cancer not having hot flushes. For symptomatic patients, the association of raloxifene with different drugs which have demonstrated efficacy in the control of vasomotor symptoms is now under evaluation.

Using a highly sensitive immunofluorometric procedure, we measured the total prostate-specific antigen (PSA) concentration in 632 sera obtained from female blood donors and women with idiopathic hirsutism, breast cancer or benign breast diseases. A total of 50 sera with total PSA > 15 ng l(-1) were fractionated by high-performance liquid chromatography (HPLC) in order to resolve the two immunoreactive molecular forms, i.e. free PSA (approximately 30 kDa) and PSA bound to alpha1-antichymotrypsin (PSA-ACT, 100 kDa). We found that breast cancer patients have presurgical serum total PSA levels similar to those of blood donors. Total serum PSA concentration decreases with age in women with idiopathic hirsutism, in cancer patients and in patients with benign breast diseases. The major molecular form of PSA in the serum of all normal and hirsute women (n = 15) is PSA bound to the proteinase inhibitor alpha1-antichymotrypsin. The major molecular form in 44% of presurgical cancer patient sera is free PSA. A total of 58% of benign breast disease patients also have in their serum mainly free PSA. We conclude that about half the patients with breast cancer or benign breast diseases have free PSA as the major molecular form in their serum, whereas patients without breast pathologies (normal blood donors, idiopathic hirsutism) have PSA bound to alpha1-antichymotrypsin as the major molecular form. The ratio of PSA/PSA-ACT may have value as a simple biochemical test for diagnosis of breast pathologies including breast cancer.

Photoelectric charging of particles is a powerful tool for online characterization of submicrometer aerosol particles. Indeed photoionization based techniques have high sensitivity and chemical selectivity. Moreover, they yield information on electronic properties of the material and are sensitive to the state of the surface. In the present study the photoionization charging efficiency, i.e., the ratio between the generated positive ions and the corresponding neutral ones, for different classes of flame-generated carbonaceous nanoparticles was measured. The fifth harmonics of a Nd:YAG laser, 213 nm (5.82 eV), was used as an ionization source for the combustion generated nanoparticles, whereas a differential mobility analyzer (DMA) coupled to a Faraday cup electrometer was used for particle classification and detection. Carbonaceous nanoparticles in the nucleation mode, i.e., sizes ranging from 1 to 10 nm, show a photoionization charging efficiency clearly dependent on the flame conditions. In particular, we observed that the richer the flame is, i.e., the higher the equivalent ratio is, the higher the photon charging efficiency is. We hypothesized that such an increase in the photoionization propensity of the carbonaceous nanoparticles from richer flame condition is associated to the presence within the particles of larger aromatic moieties. The results clearly show that photoionization is a powerful diagnostic tool for the physical-chemical characterization of combustion aerosol, and it may lead to further insights into the soot formation mechanism. © 2013 American Chemical Society.
