ABSTRACT

OBJECTIVE: Vaginal dryness is an important factor influencing sexual function in women with primary Sjögren syndrome (pSS). Previous studies showed a higher degree of inflammation in vaginal biopsies from patients with pSS compared to non-pSS controls. However, the molecular pathways that drive this inflammation remain unclear. Therefore, the aim of this study was to investigate inflammatory pathway activity in the vaginal tissue of patients with pSS. METHODS: Vaginal biopsies of 8 premenopausal patients with pSS experiencing vaginal dryness and 7 age-matched non-pSS controls were included. Expression of genes involved in inflammation and tissue homeostasis was measured using NanoString technology and validated using TaqMan Real-Time PCR. Vaginal tissue sections were stained by immunohistochemistry for myxovirus resistance protein 1 (MxA) and CD123 (plasmacytoid dendritic cells [pDCs]). RESULTS: The most enriched pathway in vaginal biopsies from patients with pSS compared to non-pSS controls was the interferon (IFN) signaling pathway (P < 0.01). Pathway scores for Janus kinase and signal transducer and activator of transcription (JAK-STAT) and Notch signaling were also higher (P < 0.01 for both pathways). Conversely, transforming growth factor-ß signaling and angiogenesis pathway scores were lower in pSS (P = 0.02 and P = 0.04, respectively). Differences in IFN signaling between patients with pSS and non-pSS controls were confirmed by PCR and MxA tissue staining. No CD123+ pDCs were detected in vaginal biopsies. IFN-stimulated gene expression levels correlated positively with CD45+ cell numbers in vaginal biopsies and serum anti-SSA/Ro positivity. CONCLUSION: Upregulation of IFN signaling in vaginal tissue of women with pSS, along with its association with tissue pathology, suggests that IFNs contribute to inflammation of the vaginal wall and potentially also to clinical symptomatology (ie, vaginal dryness).

ABSTRACT

Vaginal administration is a promising route for the local treatment of infectious vaginal diseases since it can bypass the first-pass metabolism, drug interactions, and adverse effects. However, the commercial products currently available for topical vulvovaginal treatment have low acceptability and do not adequately explore this route. Mucoadhesive systems can optimize the efficacy of drugs administered by this route to increase the retention time of the drug in the vaginal environment. Several polymers are used to develop mucoadhesive systems, among them chitosan, a natural polymer that is highly biocompatible and technologically versatile. Thus, the present review aimed to analyze the studies that used chitosan to develop mucoadhesive systems for the treatment of local vaginal infections. These studies demonstrated that chitosan as a component of mucoadhesive drug delivery systems (DDS) is a promising device for the treatment of vaginal infectious diseases, due to the intrinsic antimicrobial activity of this biopolymer and because it does not interfere with the effectiveness of the drugs used for the treatment.

ABSTRACT

We characterized the vaginal ecosystem during common infections of the female genital tract, as vulvovaginal candidiasis (VVC, n = 18) and Chlamydia trachomatis infection (CT, n = 20), recruiting healthy (HC, n = 21) and bacterial vaginosis-affected (BV, n = 20) women as references of eubiosis and dysbiosis. The profiles of the vaginal microbiome and metabolome were studied in 79 reproductive-aged women, by means of next generation sequencing and proton based-nuclear magnetic resonance spectroscopy. Lactobacillus genus was profoundly depleted in all the genital infections herein considered, and species-level analysis revealed that healthy vaginal microbiome was dominated by L. crispatus. In the shift from HC to CT, VVC, and BV, L. crispatus was progressively replaced by L. iners. CT infection and VVC, as well as BV condition, were mainly characterised by anaerobe genera, e.g. Gardnerella, Prevotella, Megasphaera, Roseburia and Atopobium. The changes in the bacterial communities occurring during the genital infections resulted in significant alterations in the vaginal metabolites composition, being the decrease of lactate a common marker of all the pathological conditions. In conclusion, according to the taxonomic and metabolomics analysis, we found that each of the four conditions is characterized by a peculiar vaginal microbiome/metabolome fingerprint.

ABSTRACT

PURPOSE: Deep infiltrating endometriosis (DIE) is defined as an endometriotic lesion penetrating to a depth of >5 mm and is associated with pelvic pain, but the underlying mechanisms are unclear. Our objective is to investigate whether plasminogen activator inhibitor-1 expression (PAI-1) in endometriotic tissues is increased in women with DIE. METHODS: In this blinded in vitro study, immunohistochemistry and Histoscore were used to examine the expression of PAI-1 in glandular epithelium (GECs) and stroma (SCs) in a total of 62 women: deep infiltrating uterosacral/rectovaginal endometriosis (DIE; n = 13), ovarian endometrioma (OMA; n = 14), superficial peritoneal uterosacral/cul-de-sac endometriosis (SUP; n = 23), uterine (eutopic) endometrium from women with endometriosis (UE; n = 6), and non-endometriosis eutopic endometrium (UC; n = 6). The following patient characteristics were also collected: age, American Fertility Society stage, hormonal suppression, phase of menstrual cycle, dysmenorrhea score and deep dyspareunia score. RESULTS: PAI-1 expression in GECs and SCs of the DIE group was significantly higher than that of SUP group (p = 0.01, p = 0.01, respectively) and UE group (p = 0.03, p = 0.04, respectively). Interestingly, increased PAI-1 expression in GECs and SCs was also significantly correlated with increased dysmenorrhea (r = 0.38, p = 0.01; r = 0.34, p = 0.02, respectively). CONCLUSIONS: We found higher expression of PAI-1 in DIE, and an association between PAI-1 and worse dysmenorrhea.

ABSTRACT

INTRODUCTION: Vulvo-vaginal atrophy affects the daily lives of most post-menopausal women. We know that ospemifene intake can induce vaginal epithelial improvements within a few weeks; however, direct evidence of the effects of ospemifene on the human vulva and on connective tissue of both the vagina and vulva are lacking. AIM: To evaluate the changes induced by ospemifene on epithelium thickness, glycogen content proliferation index, collagen content, and type I/III collagen ratio in vulvar and vaginal tissue of post-menopausal women. METHODS: 20 women who attended our gynecologic clinic for planned surgery were recruited for the study. 11 subjects were taking ospemifene at the time of inclusion, and 9 subjects who were not taking ospemifene were selected as control group. Vaginal and vulvar biopsies were taken during surgery. Histological features and glycogen content were evaluated by standard hematoxylin-eosin and periodic acid-Schiff staining, total collagen and collagen type I/III ratio were evaluated by hydroxyproline assay and Sirius red staining, while the expression of Ki67 was evaluated by immunohistochemistry. MAIN OUTCOME MEASURE: We analyzed histological features of the epithelial and stromal layer of the vaginal and vulvar vestibule mucosa. RESULTS: Vaginal and vulvar biopsies from women taking ospemifene showed an increased epithelium thickness, glycogen content, and proliferation index compared with the control group. Collagen content was also higher in women taking ospemifene, while an increased ratio between type I and III collagen fibers was found only at vaginal level. CLINICAL IMPLICATIONS: Our study shows that the effectiveness of ospemifene on vaginal tissue also extends to the vulvar vestibule. STRENGTH & LIMITATIONS: This study provides direct evidence of the impact of ospemifene on vaginal and vulvar tissue. A specifically designed longitudinal study may further support our findings. CONCLUSION: Ospemifene intake is associated with a marked improvement of various morphological and physiological features of both vaginal and vulvar vestibule epithelium, including the collagen content of the tissues.

ABSTRACT

So-called gastric-type adenocarcinoma and related premalignant lesions have been characterized in the cervix, but similar lesions are not widely recognized in the vagina. We report a series of 11 vaginal glandular lesions exhibiting gastric differentiation, comprising 5 cases of adenocarcinoma and 6 of adenosis. All cases occurred in adults (aged 33 to 69) with no known history of diethylstilboestrol exposure. The vaginal adenocarcinomas exhibited morphologic features identical to gastric-type adenocarcinoma of the cervix, but 1 case additionally demonstrated basaloid and sarcomatoid components, which have not been previously reported in cervical gastric-type adenocarcinoma. Immunohistochemically, the adenocarcinomas were positive for MUC6 (4/5), PAX8 (3/5), CK7 (5/5), CK20 (1/5), CDX2 (5/5), CA19.9 (5/5), CEA (4/5), CA125 (5/5), and hepatocyte nuclear factor 1ß (5/5). p16, estrogen receptor, and Napsin A were negative in all cases tested, whereas p53 exhibited mutation-type staining in 3/5 cases. In all 5 adenocarcinomas, a component of adenosis with benign or atypical nuclear features was identified; the adenosis displayed gastric morphology in 4 cases and tuboendometrial morphology in 1. The 6 cases of pure vaginal adenosis (without associated adenocarcinoma) all contained gastric-type mucinous glands together with tuboendometrial glands in 2 cases. There was focal intestinal differentiation with goblet cells in all 6 cases and neuroendocrine cells with eosinophilic granules in 3. Cytologic atypia was observed in 4/6 cases of pure vaginal adenosis. Immunohistochemically, the gastric-type adenosis (10 cases) was positive for MUC6 (10/10), estrogen receptor (5/10), PAX8 (8/10), CK7 (9/9), CK20 (2/9), CDX2 (5/9), CA19.9 (8/9), CEA (6/9), CA125 (6/9), hepatocyte nuclear factor 1ß (10/10), and Napsin A (1/10). p53 exhibited wild-type immunoreactivity in all 10 cases, whereas p16 was negative in all cases tested. Scattered individual chromogranin-positive cells were present in all 5 cases of pure adenosis tested. Follow-up was available in 4 of the adenocarcinoma cases, with 3 patients dead of disease within 1 to 3 years and 1 patient alive with disease at 1 year. The morphologic and immunohistochemical findings in our study suggest a close relationship between vaginal gastric-type adenocarcinoma and adenosis exhibiting gastric differentiation. This probably represents a distinct pathway of vaginal gastric-type carcinogenesis analogous to that occurring in the cervix. We propose that gastric-type adenocarcinoma be recognized as a distinct histologic subtype of vaginal adenocarcinoma while vaginal adenosis of gastric-type represents a novel subtype of adenosis that requires further study to clarify its biological potential.

ABSTRACT

The composition of vaginal microbiome in menopause and cancer survivor women changes dramatically leading to genitourinary syndrome of menopause (GSM) in up to 70% of patients. Recent reports suggest that laser therapy may be valuable as a not hormonal therapeutic modality. The aim of the present study was to evaluate the effects of fractional CO2 laser treatment on the vaginal secretory pathway of a large panel of immune mediators, usually implicated in tissue remodeling and inflammation, and on microbiome composition in postmenopausal breast cancer survivors. The Ion Torrent PGM platform and the Luminex Bio-Plex platform were used for microbiome and immune factor analysis. The significant reduction of clinical symptoms and the non-significant changes in vaginal microbiome support the efficacy and safety of laser treatment. Moreover, the high remodeling status in vaginal epithelium is demonstrated by the significant changes in inflammatory and modulatory cytokine patterns. Laser therapy can be used for the treatment of GSM symptoms and does not show any adverse effects. However, further studies will be needed to clarify its long-term efficacy and other effects.

ABSTRACT

The objective is to review how the cell-specific amounts of intracellular androgens are all made in women from circulating dehydroepiandrosterone (DHEA) in each peripheral tissue, independently from the rest of the body. Following 500 million years of evolution, approximately three dozen cell-specific intracrine enzymes have been engineered in human peripheral tissues whereby the inactive sex steroid precursor DHEA mainly of adrenal origin is transformed into the appropriate minute intracellular amounts of androgens. These intracellular androgens are inactivated in the same cells, with no biologically significant release of active androgens in the circulation. The best estimate is that approximately 50% as much androgens are synthesized in women, compared to men of the same age. The problem with DHEA, however, the exclusive source of androgens in women of all ages, is that DHEA secretion has already decreased by an average of 60% at time of menopause and continues to decrease thereafter. The human-specific and highly sophisticated mechanisms of intracrinology permit each cell to control androgen availability according to its own needs independently from the remaining of the body. Such a mechanism is completely different from classical endocrinology well understood in men where testosterone of testicular origin is transported through the blood and has indiscriminate access to the androgen receptor (AR) in all AR-containing cells of the body. In men, both the endocrine and intracrine mechanisms are in operation while, in women, only the intracrine mechanisms responsible for intracellular formation from DHEA provide androgens.

ABSTRACT

BACKGROUND: The natural course of sexually transmitted infections caused by Chlamydia trachomatis varies between individuals. In addition to parasite and host effects, the vaginal microbiota might play a key role in the outcome of C. trachomatis infections. Interferon-gamma (IFN-γ), known for its anti-chlamydial properties, activates the expression of indoleamine 2,3-dioxygenase (IDO1) in epithelial cells, an enzyme that catabolizes the amino acid L- tryptophan into N-formylkynurenine, depleting the host cell's pool of tryptophan. Although C. trachomatis is a tryptophan auxotroph, urogenital strains (but not ocular strains) have been shown in vitro to have the ability to produce tryptophan from indole using the tryptophan synthase (trpBA) gene. It has been suggested that indole producing bacteria from the vaginal microbiota could influence the outcome of Chlamydia infection. RESULTS: We used two in vitro models (treatment with IFN-γ or direct limitation of tryptophan), to study the effects of direct rescue by the addition of exogenous indole, or by the addition of culture supernatant from indole-positive versus indole-negative Prevotella strains, on the growth and infectivity of C. trachomatis. We found that only supernatants from the indole-positive strains, P. intermedia and P. nigrescens, were able to rescue tryptophan-starved C. trachomatis. In addition, we analyzed vaginal secretion samples to determine physiological indole concentrations. In spite of the complexity of vaginal secretions, we demonstrated that for some vaginal specimens with higher indole levels, there was a link to higher recovery of the Chlamydia under tryptophan-starved conditions, lending preliminary support to the critical role of the IFN-γ-tryptophan-indole axis in vivo. CONCLUSIONS: Our data provide evidence for the ability of both exogenous indole as well as supernatant from indole producing bacteria such as Prevotella, to rescue genital C. trachomatis from tryptophan starvation. This adds weight to the hypothesis that the vaginal microbiota (particularly from women with lower levels of lactobacilli and higher levels of indole producing anaerobes) may be intrinsically linked to the outcome of chlamydial infections in some women.

ABSTRACT

Müllerianosis is the term used to designate lesions composed of an admixture of two or three types of müllerian-derivation glands in heterotopic location. In this report, we describe a case of incidental vaginal müllerianosis in a 59-year-old woman who underwent rectosigmoidectomy for rectal adenocarcinoma. In the vaginal cuff removed for neoplastic invasion, a separate multilocular mass measuring 1.5cm was found. The microscopic examination of the vaginal wall revealed endosalpingeal, endocervical and endometrial dilated or cystic glands with predominance of the endosalpingeal epithelium. Müllerian epithelium showed positivity for cytokeratins 7 and 8/18, high molecular weight cytokeratin, estrogen receptor alpha, and androgen receptor. The periglandular stroma was condensed and reactive for smooth-muscle actin, h-caldesmon, and CD10. To the best of our knowledge, a case of vaginal müllerianosis has not been previously reported. This lesion should be differentiated form vaginal adenosis and primary well-differentiated vaginal adenocarcinoma. The vagina should be added to the list of locations in which müllerianosis can be observed.

ABSTRACT

Many natural substances were screened to develop nutraceuticals that reduce menopausal symptoms. A complex of Cirsium japonicum var. maackii and Thymus vulgaris extracts, named MS-10, had significant positive effects. Under a low concentration of estrogen, which represents postmenopausal physiological conditions, MS-10 had beneficial effects on estrogen receptor-expressing MCF-7 cells by reversibly enhancing estrogen activity. In addition, in the ovariectomized rat model, changes in bone-specific alkaline phosphatase activity and osteocalcin, as well as low-density lipoprotein cholesterol and triglyceride levels were significantly decreased by MS-10. These results show that MS-10 protected bone health and reduced metabolic disturbances. Furthermore, in a clinical study, all menopausal symptoms, including hot flushes, parenthesis, insomnia, nervousness, melancholia, vertigo, fatigue, rheumatic pain, palpitations, formication, and headache, as well as colpoxerosis, were significantly improved by taking MS-10 for 90 days. Therefore, the evidence supports that MS-10 is an effective natural substance that can safely improve menopausal symptoms, including colpoxerosis.

ABSTRACT

OBJECTIVES: Describe the effect of 50 mcg vaginal 17-ß-estradiol (E2) cream on vaginal maturation, serum estrogen levels, atrophic symptoms, and biomarkers of oxidative stress and tissue remodeling in postmenopausal women without prolapse. METHODS: Seventeen women, 65 years or older, applied intravaginal E2 cream nightly for eight weeks, then twice weekly for eight weeks. Vaginal biopsies, serial blood draws, and atrophic symptoms were obtained at baseline, eight, and sixteen weeks. Changes in atrophic symptoms, vaginal maturation indices (VMI), and serum E2 were measured. Immunohistochemical staining characterized levels of transforming growth factor-beta (TGF-ß), nuclear factor kappa B (NFKB), inducible nitric oxide synthase (iNOS), endothelial nitric oxide synthase (eNOS), and thrombospondin (TSP). RESULTS: Serum E2 levels (pg/ml) were unchanged from baseline (mean (SD)) 7.7 (3.3) to eight 9.7 (5.7) and sixteen 8.7 (5.8) (p=0.24) weeks. VMI (mean (SD)) improved from baseline 34.2 (18.3) to eight 56.7 (13.1) and sixteen 54.5 (11.3) (p<0.001) weeks with no difference between eight and sixteen weeks. Vaginal dryness (p=0.03) and itching (p=0.02) improved. Tissue biomarker levels did not change (TGF-ß p=0.35, NFKB p=0.74, eNOS p=0.80, iNOS p=0.24, TSP p=0.80). DISCUSSION: Vaginal E2 improved atrophic symptoms and VMI without elevating serum E2. Tissue remodeling biomarkers did not change.

ABSTRACT

OBJECTIVE: To study the density of nerve fibers in cases of deep infiltrating endometriosis (DIE) of the rectovaginal septum in relation to various clinical factors. DESIGN: A research laboratory-based study. SETTING: A tertiary center together with a research laboratory. METHODS: Archived DIE tissue samples from 45 women operated upon for rectovaginal septum DIE were re-examined histologically, and by immunohistochemistry. MAIN OUTCOME MEASURES: The effect of progestogens or combined oral contraceptives on the density of nerve fibers, and the expression of nerve growth factor (NGF) and its high-affinity receptor (tyrosine kinase receptor A, Trk-A). RESULTS: The use of hormonal therapy was associated with reduced densities of sympathetic, parasympathetic and sensory nerve fibers in DIE lesions. Density of total nerve fibers (with pan-neuronal marker PGP9.5) was significantly lower (p < 0.05) in lesions collected from hormone-treated women (8.6/mm², 4.2-20.8/mm²; median density, from 25th to 75th quartiles) compared with that in lesions from untreated women (24.9/mm², 11.2-34.9/mm²). DIE lesions stained strongly for NGF and its receptor Trk-A. Expression of NGF, but not of Trk-A, was significantly reduced during use of hormonal therapy. CONCLUSIONS: Use of hormonal therapy was associated with significantly reduced nerve fiber density in DIE lesions. This may be an important mechanism of action of hormonal therapy for controlling DIE pain symptoms. The expression of estrogen-regulated NGF and its receptor was only partially suppressed during the use of hormonal therapy, suggesting that local estrogen action is often maintained during conventional hormonal therapy in cases of DIE.

ABSTRACT

GATA binding protein 3 (GATA3) is a recently described immunohistochemical marker that has proven useful in the characterization of breast and urothelial carcinomas. However, the expression pattern of GATA3 in mesonephric proliferations is largely unknown. The aim of this study was to examine the immunohistochemical expression of GATA3 in cervicovaginal mesonephric lesions and compare it to its expression in endocervical and endometrial adenocarcinomas and cervicovaginal endometriosis. A cohort of 107 cases, including 33 cases of mesonephric lesions and 74 cases of nonmesonephric lesions, was selected for the study. Of 33 mesonephric lesions, 31 (94%) cases (16 remnants, 12 hyperplasias, and 3 adenocarcinomas) were strongly and diffusely positive in tumor cell nuclei for GATA3. The remaining 2 mesonephric carcinosarcomas showed focal nuclear staining and rare nuclear positivity, respectively. Of 36 endocervical adenocarcinomas, 33 (92%) were negative for GATA3 and the remaining revealed focal weak nuclear staining. Of 34 endometrial adenocarcinomas, 32 (94%) were negative, whereas 2 showed rare nuclear positivity. All 4 cases of endometriosis were negative. The benign endocervical epithelium and the benign endometrium in most cases lacked GATA3 expression, whereas the benign squamous epithelium in the majority exhibited nuclear basal and parabasal staining pattern. Our study demonstrates that GATA3 protein is expressed in most mesonephric lesions, regardless of them being benign or malignant. In contrast, GATA3 is absent in the majority of endometrial and endocervical adenocarcinomas. These results support that GATA3 immunostain can be a useful tool in differentiating mesonephric lesions from endocervical and endometrial adenocarcinomas.

ABSTRACT

BACKGROUND: Gartner duct cysts represent vestigial remnants of the caudal end of the mesonephric (Wolffian) ducts. They are often associated with ureteral and renal abnormalities. In most cases they are solitary, less than 2 cm in diameter. Giant Gartner duct cysts are extremely rare. CASE: We present a girl with a giant Gartner duct cyst, without notable associated abnormalities or pathology, successfully treated by surgical excision. Preoperative aspiration revealed elevated level of CA-125 in the cyst fluid, with normal serum level of the same marker. CONCLUSION: Analyzing the aspirated fluid for CA-125 may be a useful tool for evaluation of cystic lesions in this region.

ABSTRACT

OBJECTIVE: Evaluate the effects of vaginal administration of isoflavones derived from Glycine max (L.) Merr. as a treatment option for vaginal atrophy, on the morphology and expression of estrogen receptors in vaginal epithelium of postmenopausal women. METHODS: The double-blind, randomized, placebo-controlled, clinical trial. Sixty women were treated for 12 weeks with isoflavone vaginal gel 4% (1g/day) and a placebo gel. After 4 and 12 weeks, the vaginal atrophy symptoms were classified at none, mild, moderate and severe and the vaginal cytology were taken to determine the maturation value. Vaginal pH was measured at the beginning and end of therapy. Microbiopsies in vaginal fornix were performed before the treatment and after 12 weeks of treatment. RESULTS: Isoflavone vaginal gel was effective for relief of vaginal dryness and dyspareunia symptons and an increase in the intermediate and superficial cells was noted. The vaginal pH in the isoflavone group was 7.1 at baseline and 5.4 after 12 weeks, whereas in the placebo group there was no significant change. A significant increase in thickness after treatment was detected in the Isoflavone Group. The percentage of estrogen receptor positive cells in vaginal epithelium for the Isoflavone Group ranged from 58.5% at the beginning of treatment to 82.6% after 12 weeks. These results were superior to placebo gel. CONCLUSION: Glycine max (L.) Merr. at 4% vaginal gel on a daily basis in postmenopausal women led to improvements in vaginal atrophy symptoms, maturation values, vaginal pH, morphology and expression of estrogen receptors in vaginal epithelium. Isoflavones proved good treatment options for relief of vulvovaginal atrophy.

ABSTRACT

BACKGROUND: Bacterial vaginosis (BV) is the most common vaginal disorder of reproductive-age women. Yet the cause of BV has not been established. To uncover key determinants of BV, we employed a multi-omic, systems-biology approach, including both deep 16S rRNA gene-based sequencing and metabolomics of lavage samples from 36 women. These women varied demographically, behaviorally, and in terms of health status and symptoms. PRINCIPAL FINDINGS: 16S rRNA gene-based community composition profiles reflected Nugent scores, but not Amsel criteria. In contrast, metabolomic profiles were markedly more concordant with Amsel criteria. Metabolomic profiles revealed two distinct symptomatic BV types (SBVI and SBVII) with similar characteristics that indicated disruption of epithelial integrity, but each type was correlated to the presence of different microbial taxa and metabolites, as well as to different host behaviors. The characteristic odor associated with BV was linked to increases in putrescine and cadaverine, which were both linked to Dialister spp. Additional correlations were seen with the presence of discharge, 2-methyl-2-hydroxybutanoic acid, and Mobiluncus spp., and with pain, diethylene glycol and Gardnerella spp. CONCLUSIONS: The results not only provide useful diagnostic biomarkers, but also may ultimately provide much needed insight into the determinants of BV.

ABSTRACT

Introducción: Muchas usuarias del sistema público de salud español contratan además un seguro privado para mejorar los controles ginecológicos y exploraciones rutinarias como mamografía anual. Analizamos retrospectivamente el pronóstico de estas pacientes cuando son diagnosticadas de cáncer de mama y se tratan con cirugía de intención curativa. Material y métodos: Se analizan la supervivencia global y los factores pronósticos de pacientes diagnosticadas de cáncer de mama sin metástasis tratadas con cirugía curativa en el contexto de un tratamiento multidisciplinario, remitidas a una consulta de oncología médica dentro de un sistema sanitario privado extra. Resultados: Entre 1994 y 2009 se analizaron 395 pacientes con cáncer de mama. Treinta y ocho tenían metástasis al diagnóstico y 357 pudieron tratarse con cirugía curativa: conservadora en 265 casos y mastectomía en 92. Con mediana de seguimiento de 64 meses, la tasa de supervivencia a 5 años era 91%: 97% para estadios I, 94% para estadios II, y 77% para estadios III. En las que se diagnosticaron por mamografía sistemática fue del 96 frente al 86% en las que acudieron al ginecólogo por autopalpación de tumor u otros síntomas (p = 0,0159). En el 74% se realizo ́ tratamiento conservador con mejor supervivencia frente al 26% que se realizó mastectomía (p = 0,0024). Pacientes con receptores positivos tuvieron mejor supervivencia que con receptores negativos (p = 0,0264) y este fue el único factor pronóstico independiente en el análisis multivariado de Cox. Conclusiones: Las pacientes con cáncer de mama tratadas con cirugía de intención curativa en un sistema sanitario privado tienen alta tasa de curación probablemente por tener un diagnóstico en fase precoz (AU)


Introduction: Many women enrolled in the Spanish National Health Service also take out private health insurance to improve gynecological follow-up and complementary examinations, such as annual mammograms. We analyzed the cure rate of these patients when diagnosed with breast cancer and treated with surgery with curative intent. Material and methods: Both overall survival and prognosis were analyzed in patients with breast cancer without metastases referred to a private oncology facility and treated with definitive surgery in the context of multidisciplinary treatment. Results: Between 1994 and 2009, 395 patients with breast cancer were analyzed. Thirty- eight had metastases at diagnosis and 357 could be treated with definitive surgery: conservative in 265 patients and mastectomy in the remaining 92. The median follow-up was 64 months and the 5-year survival rate was 91%: 97% for stage I, 94% for stage II and 77% for stage III. In women diagnosed by mammography, the 5-year survival rate was 96% versus 86% for women consulting a gynecologist after self palpation or for other symptoms (p = 0.0159). Treatment was conservative in 74%, with better survival than in the remaining 26% who were treated with mastectomy (p = 0.0024). Survival was greater in patients with positive hormone receptors than in those with negative hormone receptors (p = 0.0264). Hormone receptor status was the only independent prognostic factor in multivariate Cox analysis. Conclusions: Patients with breast cancer treated with definitive surgery in a private health insurance system have high cure rate, possibly because they are diagnosed in an early stage (AU)

ABSTRACT

The author describes 3 cases of an unusual vaginal lesion, designated as "vaginal stromal sclerosis," that is believed to represent a clinically and pathologically distinct disease. The 3 patients, aged 62, 52, and 50 years, all presented with dyspareunia and had clinical evidence of vaginal atrophy. The lesions were either a solitary firm vaginal nodule (2 cases) or multiple firm distal vaginal plaques (1 case), each of which measured less than 1 cm. All were nontender and nonfluctuant. Microscopically, the lesions were characterized by poorly delineated, diffuse zones of stromal paucicellular hyalinization, comprising fine collagen and elastic fibers, which extended upward to the basement membrane layer of the overlying epithelium, and downward to the deepest portions of most of the biopsies. Constituent cells were largely monomorphic, with irregular, pyknotic nuclei and small cytoplasmic extensions. Mitotic figures or tissue necrosis were not identified. There were small, thin-walled, capillary-caliber vessels in the upper layers of the hyalinized zone, whereas the deeper areas displayed larger caliber arteries in addition to small vessels. Occasional plaques of eosinophilic collagen were observed in 2 cases. Epithelial changes included hyperkeratosis in 1 case, and mild-to-moderate atrophy with loss of normal rugae formation in all 3 cases. Histochemical studies for Congo-red (amyloid), Gomori-Methamine-Silver (fungal forms), and phosphotungstic acid hematoxylin (fibrin) were negative. An elastin histochemical study showed a marked increase in elastic fibers within the stromal compartment relative to the adjacent normal vaginal stroma. By immunohistochemistry, the stromal cells were diffusely positive for vimentin, and were negative for CD34, desmin, smooth muscle actin, muscle-specific actin, progesterone receptor, and p53 in all 3 cases. The paucicellular foci of hyalinization were similarly vimentin positive. The stromal cells displayed diffuse immunoreactivity for the estrogen receptor in 2 cases and were negative in the third case. The uniform clinical presentation of dyspareunia and vaginal atrophy, the notably firm consistency of the nodules and plaques, and the distinctive morphologic features, all suggest that this lesion is worthy of segregation. Potential differential diagnostic considerations are discussed. It is postulated that this lesion is an unusual reparative stromal change that may be related to atrophy-related vaginal irritation or injury.

ABSTRACT

BACKGROUND: In a university hospital setting, a 25-year-old woman presented with large vaginal and cervical polyps. Past medical history was significant for stage IV endometriosis. Polypectomy was performed and the polyps were histologically consistent with endometriosis. Gene expression was compared with control vaginal tissue to assess if the altered gene expression profile was similar to peritoneal endometriosis. METHODS AND RESULTS: Using quantitative reverse transcription, real-time PCR, estrogen receptor-ß expression was found to be upregulated 10-fold while estrogen receptor-α expression was downregulated 5-fold in the vaginal polyp relative to control vaginal tissue. The estrogen-synthesizing enzyme aromatase was upregulated 8-fold and 3ß-hydroxysteroid dehydrogenase was upregulated 400-fold in the polyp. Immunohistochemical staining revealed altered cell type localization for progesterone receptor in the polyp and increased cell proliferation in polyp stromal cells relative to control. CONCLUSIONS: Increased proliferation in the vaginal polypoid endometriotic tissue may be due to increased local estrogen production. The altered gene expression profile was very similar to the altered gene expression profile seen in peritoneal endometriosis.
