The importance of the learning curve and surveillance of surgical performance in peritoneal surface malignancy programs.
No full textCytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are complex procedures with a very steep a learning curve (LC). This study evaluates the LC of CRS and HIPEC in a single-center experience of peritoneal surface malignancies (PSMs). Approximately 140 to 150 cases were necessary for the acquisition of competence in CRS and HIPEC with adequate radicality and acceptable safety. Eighty to 100 cases were necessary to assure short-term prognostic gains in rare PSMs. This article highlights how LC and continuous monitoring of surgical performance is critical in evaluating the credibility of emerging and already established PSM centers
The consensus statement on the locoregional treatment of abdominal sarcomatosis.
No full textAbdominal sarcomatosis (AS) is a rare condition characterized by soft tissue sarcoma spreading throughout the abdomen, in the absence of extra-abdominal dissemination. Retroperitoneal sarcomas, pelvic sarcomas, particularly uterine leiomyosarcoma and gastrointestinal stromal tumors (GISTs) most frequently give rise to AS. Systemic chemotherapy is the standard of care for AS from non-GIST sarcomas. but with an essentially palliative aim and major limitations. Innovative targeted therapies has deeply affected the natural history of GIST, at least in prolonging significantly survival in responsive patients. In this context, the notion that abdominal spread in the lack of extra-peritoneal lesions may typically occur in a number of patients, along with the dismal prognosis generally carried by AS, has prompted a few centers to perform cytoreductive surgery and perioperative intraperitoneal chemotherapy. To date, the rarity of these presentations makes it difficult to evaluate the clinical results and the role of combined local-regional treatment is still a matter of debate. This article presents the results of a group of experts from around the World trying to achieve a consensus statement in AS comprehensive management. A questionnaire was placed on the website of the 5th International Workshop on Peritoneal Surface Malignancy and the experts voted via internet
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
Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) in a patient with peritoneal mesothelioma and HIV infection.
No full textVariations 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
