Fertility-sparing management of low-grade endometrial stromal sarcoma: Analysis of an institutional series and review of the literature
No full textObjective Low-grade endometrial stromal sarcoma (LG-ESS) is a rare malignancy, often occurring before menopause. There is no consensus regarding its optimal management. Total hysterectomy and bilateral salpingo-oophorectomy precludes future fertility and may thus be undesirable by women wishing to maintain their reproductive potential. However, experience of fertility-sparing management in LG-ESS is very limited. In this paper, the disease outcome is presented in six young women with LG-ESS conservatively treated by combined hysteroscopic resection and hormonal therapy. Study design From October 2009 to February 2013, at the Gynecologic Oncology Department of the National Cancer Institute of Naples, six women, with early-stage LG-ESS aged 18-40 years who desired childbearing and/or retaining their fertility, were enrolled into a pilot study of fertility-sparing management. Diagnosis of LG-ESS was made on specimens from hysteroscopic resection performed on a presumed benign lesion. All patients were planned to be treated with adjuvant megestrol acetate for two years. Hormonal therapy was started within 6 weeks from the hysteroscopic resection, with orally megestrol acetate at 40 mg daily, increasing gradually according to patient's tolerance to the recommended total dose of 160 mg daily. Results All patients were submitted to hysteroscopic resection in a one-step procedure. Five patients started megestrol acetate within 6 weeks from the hysteroscopic resection (one patient did not start hormonal therapy because of early pregnancy after the hysteroscopic resection). Hormonal therapy was well tolerated; one patient stopped megestrol acetate after 12 months because of self-supporting strong desire to conceive; the other four patients regularly completed the hormonal therapy. To date, all patients show no evidence of disease. Conclusions Although fertility-sparing management is not the current standard of care for young women with early-stage LG-ESS, our preliminary data are promising. Larger series with a longer follow-up are needed to further assess safety and efficacy of combined hysteroscopic resection and hormonal therap

Primary surgical cytoreduction in advanced ovarian cancer: An outcome analysis within the MITO (Multicentre Italian Trials in Ovarian Cancer and Gynecologic Malignancies) Group
Full text linkObjective To draw a reliable picture of the surgical management of advanced ovarian cancer (AOC) within the MITO Group, trying to correlate the disease extent at presentation, the category of center, and surgical outcome. Methods Three tertiary referral centers for gynecologic oncology and four non-oncologic referral gynecologic surgical centers, participated in the project. A questionnaire was adopted to register perioperative data on AOCs (FIGO Stage IIIC-IV) consecutively operated on for a period of 12 months. Results A total of 205 patients were registered into the study: 140 and 65 were recruited in oncological referral centers and non-referral centers, respectively. Following a multivariate analysis, the Eisenkop score and the category of center resulted the most potent predictors of complete surgical cytoreduction followed by PCI, preoperative CA125, and ASA score. Complete surgical cytoreduction was associated with oncological referral centers (60% vs 24.6%, p < 0.001). The proportion of patients undergoing additional surgical procedures was significantly different comparing the two categories of centers (at least one additional procedure was performed in 81.4% vs 50.8% in oncological referral centers compared to the others, p < 0.001). Despite the more aggressive surgery performed in oncological referral centers, the perioperative outcome measures were not significantly different in the two groups. Conclusions The chance of obtaining a complete cytoreduction mainly depends on patient characteristics, tumor spread, and quality of treatment. The latter is amenable for direct influence, and therefore, seems to be of utmost importance when considering efforts aiming at improvement in the outcome of this disease
Minimally Invasive Surgical Staging for Ovarian Carcinoma: A Propensity-Matched Comparison With Traditional Open Surgery
No full textGrowing evidence supports the safety of a laparoscopic approach for patients affected by apparent early-stage ovarian cancer. However, no well-designed studies comparing laparoscopic and open surgical staging are available. In the present investigation we aimed to provide a balanced long-term comparison between these 2 approaches
Chemoembolization, Radioembolization, and Percutaneous Ablation: New Opportunities for Treating Ovarian Cancer Liver Metastasis
No full textParenchymal liver metastases from ovarian cancer, occurring in 2–12.5% of cases, significantly worsen prognosis. While surgery and systemic treatments remain primary options, unresectable or chemotherapy-resistant multiple liver metastases pose a significant challenge. Recent advances in liver-directed therapies, including radiofrequency ablation, microwave ablation, cryoablation, transarterial chemoembolization (TACE), and radioembolization, offer potential treatment alternatives. However, the efficacy of these techniques is limited by factors such as tumor size, number, and location. The ideal candidate for tumor ablation is a patient with paucifocal disease, a single tumor up to 5 cm or up to 3 tumors smaller than 3 cm and tumors 1 cm away from major bile ducts and high-flow vessels. Transarterial chemoembolization could be performed in patients with less than 70% tumor load. Differently, radioembolization is available with less limitation on the sites or number of liver cancers. Radioembolization techniques are also able to downsize liver metastases. However, there are limited data regarding the outcomes of loco-regional therapy in patients with hepatic metastases from ovarian cancer. Advancing liver-directed therapies through interventional oncology, combined with robust data on the oncological efficacy of these local treatments, will validate their potential as effective locoregional therapies for liver metastases. This could offer a promising treatment option for patients with ovarian cancer and unresectable hepatic metastases
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
