    ObjectiveThe aim of the study was to evaluate the risk of recurrence according to the surgical margin status and the presence of invasion or of superficially invasive carcinoma in patients with extramammary Paget disease (EMPD) of the vulva, who underwent elective surgical treatment.Materials and MethodsWe performed a retrospective analysis of 27 patients with first diagnosis of extramammary Paget disease of the vulva, who underwent primary and elective surgical treatment from January 1989 to December 2014. A p value of less than .05 was considered statistically significant. Multivariable logistic regression was performed to adjust for confounding factors.ResultsWe observed invasive disease in 11 cases, with microinvasion in 8 of them. A positive surgical margin was found in 10 patients. During a median follow-up period of 79.5 months, 8 patients (29.6%) showed a first recurrence after a median (range) time of 4.9 (2.3-7.1) years. No significant differences were observed between patients with recurrence and patients without recurrence with respect to age, number of vulvar sectors involved, bilaterality and multifocality, presence of invasion or microinvasion, and surgical margin status. However, during the follow-up period, the presence of invasion was higher (67% vs 41%) in patients with recurrence compared with patients without recurrence.ConclusionsThe rate of recurrence of the disease after therapy is high. Patients should be subjected to a close and long-term follow-up to identify those who must undergo further treatment, especially if they presented with an invasive or even microinvasive disease. A free margin of no greater than 1 to 2 cm might be the most appropriate surgical choice

    Experimental estimation of entanglement at the quantum limit

    Entanglement is the central resource of quantum information processing and the precise characterization of entangled states is a crucial issue for the development of quantum technologies. This leads to the necessity of a precise, experimental feasible measure of entanglement. Nevertheless, such measurements are limited both from experimental uncertainties and intrinsic quantum bounds. Here we present an experiment where the amount of entanglement of a family of two-qubit mixed photon states is estimated with the ultimate precision allowed by quantum mechanics.Comment: 4 pages, 3 figure

    Aim: The aim of this study was to evaluate if the lymph node count from inguinofemoral lymphadenectomy impacted the risk of isolated groin recurrence in patients with nodenegative squamous cell vulvar cancer.Materials and Methods: This is a retrospective cohort study of women with squamous cell vulvar cancer (stage IBYII according to the 2009 Revised International Federation of Gynecology and Obstetrics staging system) who underwent primary radical vulvar surgery and groin lymphadenectomy between January 2005 and December 2014. Patients' sociodemographic characteristics, the disease characteristics, the number of nodes removed from each groin, and the oncologic outcomewere evaluated. A cutoff value of at least 6 nodes removed from each groin was used to define the adequacy of inguinofemoral dissection.Results: Seventy-six patients, fulfilling the study inclusion criteria, were considered. The mean number of nodes removed (bilaterally) was 14.5 (T5.3, SD), with a range of 2 to 29 nodes. Thirty-three women (43.4%) had less than 6 nodes removed from each groin. In the whole study cohort, 4 cases of isolated groin recurrence (5.3%) were detected, and all these recurrences developed in patients with less than 6 nodes removed. Considering the demographic, clinical, and histopathological characteristics potentially related to the risk of groin recurrence, only the number of nodes removed showed a significant correlation.Conclusions: Women treated for vulvar cancer in which less than 6 nodes are removed from each groin are at higher risk of groin recurrence

    Objective The aim of this study was to analyze women treated with excisional procedures for vaginal high-grade squamous intraepithelial lesions (HSILs). The histopathological upgrading of the lesions previously detected on vaginal biopsy and the presence of occult invasive vaginal cancer in the specimens excised were investigated, to identify a higher risk subset of women.Materials and Methods A retrospective analysis of the medical records of 86 women with a biopsy histopathologic diagnosis of vaginal HSIL (vaginal intraepithelial neoplasias [VaINs]: VaIN2 and VaIN3) and subsequent excisional therapy, consecutively referred to the Aviano National Cancer Institute (Aviano, Italy) from January 1991 to April 2014, was performed.Results Of the 86 patients, 4 cases (4.6%) of occult vaginal cancer were detected, all of them in women previously diagnosed with VaIN3 on biopsy (4/39 cases, 10.3%). Women with diagnosis of VaIN2 on biopsy showed an upgrading of lesions, with diagnosis of VaIN3 on the final specimen in 5 (10.6%) of 47 cases, with no cases of VAIN2 upgraded to invasive cancer. In 33.3% of the women initially diagnosed with VaIN2 and with previous hysterectomy for human papillomavirus-related disease, a final histopathological upgrading of lesions emerged. Furthermore, tobacco use was significantly related to the histopathological upgrading of lesions previously detected on vaginal biopsy.Conclusions Women diagnosed with VaIN3 should be treated with excisional procedures as first-line surgical approach, given the risk of occult invasive disease in 10% of the cases. Women diagnosed with VaIN2 and with previous hysterectomy for human papillomavirus-related cervical diseases should always be carefully evaluated and possibly excised, given the higher risk of histopathological upgrading of lesions and thus the potential risk of occult vaginal cancer. Tobacco users should be considered as high-risk group

    The tumor suppressor gene TRC8/RNF139 is disrupted by a constitutional balanced translocation t(8;22)(q24.13;q11.21) in a young girl with dysgerminoma

    <p>Abstract</p> <p>Background</p> <p><it>RNF139/TRC8 </it>is a potential tumor suppressor gene with similarity to PTCH, a tumor suppressor implicated in basal cell carcinomas and glioblastomas. <it>TRC8 </it>has the potential to act in a novel regulatory relationship linking the cholesterol/lipid biosynthetic pathway with cellular growth control and has been identified in families with hereditary renal (RCC) and thyroid cancers. Haploinsufficiency of <it>TRC8 </it>may facilitate development of clear cell-RCC in association with <it>VHL </it>mutations, and may increase risk for other tumor types. We report a paternally inherited balanced translocation t(8;22) in a proposita with dysgerminoma.</p> <p>Methods</p> <p>The translocation was characterized by FISH and the breakpoints cloned, sequenced, and compared. DNA isolated from normal and tumor cells was checked for abnormalities by array-CGH. Expression of genes <it>TRC8 </it>and <it>TSN </it>was tested both on dysgerminoma and in the proposita and her father.</p> <p>Results</p> <p>The breakpoints of the translocation are located within the LCR-B low copy repeat on chromosome 22q11.21, containing the palindromic AT-rich repeat (PATRR) involved in recurrent and non-recurrent translocations, and in an AT-rich sequence inside intron 1 of the TRC8 tumor-suppressor gene at 8q24.13. <it>TRC8 </it>was strongly underexpressed in the dysgerminoma. Translin is underexpressed in the dysgerminoma compared to normal ovary.</p> <p><it>TRC8 </it>is a target of Translin (TSN), a posttranscriptional regulator of genes transcribed by the transcription factor CREM-tau in postmeiotic male germ cells.</p> <p>Conclusion</p> <p>A role for <it>TRC8 </it>in dysgerminoma may relate to its interaction with Translin. We propose a model in which one copy of <it>TRC8 </it>is disrupted by a palindrome-mediated translocation followed by complete loss of expression through suppression, possibly mediated by miRNA.</p

    Objective: We undertook a retrospective analysis of the incidence of complications of carbon dioxide (CO2) laser excision for high-grade vaginal intraepithelial neoplasia (HG-VaIN).Materials and Methods: Retrospective large case series on 128 CO2 laser excisions for HG-VaIN in 106 women treated at the Department of Gynecologic Oncology, Oncologic Referral Center, Aviano, Italy. These procedures were performed under local anesthesiawith a 20-Wcontinuous laser beam focused to a 0.2-mm spot size. Complications were defined as "minor" when limited to vagina, and "major" when surrounding organs were injured or the vaginal vault was opened. To identify possible factors associated with surgical complications, we performed a univariate analysis with the t test for continuous variables and x(2) or Fisher exact test for qualitative variables as appropriate.Results: The overall rate of complication was 7.8% (10/128); nine of themwere vaginal bleeding, and only one (0.8%) was amajor complication with vaginal vault perforation. A greater number of previous destructive treatments and of two or more previous laser vaginal excisional treatments was present in patients with complications compared with ones without complications (10% vs 3.9 %, p = .92, and 30% vs 15.2%, p = .44, respectively), although these differences were not statistically significant. A total of 10.5% (6/57) of occult vaginal cancer was detected in women with initial diagnosis of VaIN3 (HG-VaIN) on biopsy.Conclusions: Carbon dioxide laser excision for HG-VaIN seems to be a safe approach with low rate of complications, probably because of the better accuracy achieved by CO2 laser resections, and permits diagnosis of occult invasive disease

    Is the endometrial evaluation routinely required in patients with adult granulosa cell tumors of the ovary?

    Get PDF
    Granulosa cell tumors (GCTs) are the most common estrogen-secreting ovarian tumors; perhaps due to the persistent hyperestrogenism, a wide spectrum of associated endometrial pathologies ranging from endometrial hyperplasia to carcinoma has been documented in patients with GCTs. The aim of this study is to evaluate the incidence of endometrial pathologies in a large series of GCT patients treated in MITO centers

    SRSF2 mutations in epithelial ovarian cancer

    Resistance to platinum chemotherapy regimens represents a major obstacle in the successful treatment of epithelial ovarian cancer (EOC) patients. Among the molecular mechanism responsible for resistance to platinum, alternative splicing, which is induced upon platinum treatment, can control apoptosis by regulating the expression of apoptotic protein variants with opposite functions. Alterations in alternative splicing are found in tumors and can hinder apoptotic response. In the present study we sequenced SRSF2, a splicing factor that regulates Caspase-8 and Caspase-9 variants, in search of mutations that could possibly explain alternative mechanisms of platinum resistant in EOC
