No full textBACKGROUND: Response of cutaneous T-cell lymphoma (CTCL) to systemic chemotherapy is unsatisfactory: despite an initially high response rate (RR), duration is always short-lived. OBJECTIVE: To investigate the capability of a third-generation regimen including idarubicin in improving RR and response duration in CTCL patients. METHODS: Twenty-five patients with advanced CTCL (stages IIB and IV) were treated with a 12-week polychemotherapeutic regimen (VICOP-B), which foresees the use of idarubicin in association with etoposide, cyclophosphamide, vincristine, prednisone and bleomycin. RESULTS: The overall objective RR was 80% (36% complete response). The mycosis fungoides (MF) RR was 84%, with a median duration of 8.7 months. The pleomorphic-lymphoma RR was higher (100%), but the corresponding response duration was shorter (median: 3 months). No responses were documented in SÚzary syndrome. CONCLUSION: VICOP-B regimen is effective and feasible as first-line chemotherapy in advanced MF, with or without extracutaneous involvement
Low-dose integrated chemoimmuno-hormonotherapy with cisplatin, subcutaneous interleukin-2, alpha-interferon and tamoxifen for advanced metastatic melanoma--a pilot study.
No full textRecently, Khayat et al. reported that high-dose recombinant interleukin-2 (rIL-2) i.v. may induce tumour regressions in metastatic melanoma patients through an association with cisplatin (CDDP) and alpha-interferon (alpha-IFN). Treatment-related toxicities are, however, important. Previous studies have demonstrated that rIL-2 toxicity may be reduced through a subcutaneous injection. In order to evaluate the effectiveness of low subcutaneous rIL-2 doses in a chemoimmuno-hormonotherapeutic combination, 36 metastatic melanoma patients were treated with CDDP, rIL-2, alpha-IFN and tamoxifen (TAM). The overall response rate was 47.2%: five patients had complete response (14%), 12 partial response (33%) and 13 stable disease (36%). Median response duration was 6.4 months (range: 2-29+). Median overall survival was 10 months (range: 3-36+). The CDDP/rIL-2/alpha-IFN/TAM regimen was effective both on soft tissue and visceral metastases. Toxicity was low and patient management did not require an intensive care unit. A statistically significant increase in both percentage and absolute values of lymphocytes, eosinophils, CD3+/CD4+, CD25+, CD16/56+ and HLA-DR+ cells was found in all patients after two treatment courses. This study shows that lower doses of subcutaneous rIL-2, as well as CDDP and alpha-IFN, associated with TAM, may have similar anticancer efficacy with respect to Khayat's schedule but lower toxicity
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
