Carboplatin and pegylated liposomal doxorubicin for advanced ovarian cancer. Preliminary activity results of the MITO-2 phase III trial
2008
<i>Background:</i> Based on the efficacy of pegylated liposomal doxorubicin (PLD) in relapsed ovarian cancer, we are conducting a phase III study comparing carboplatin plus either paclitaxel or PLD as first-line therapy in advanced ovarian cancer. Because of limited phase I and II data on PLD plus carboplatin in this setting, we conducted an interim activity analysis. <i>Patients and Methods:</i> Patients with stage 1c-IV epithelial ovarian cancer were randomized to carboplatin AUC 5 plus either paclitaxel 175 mg/m<sup>2</sup> or PLD 30 mg/m<sup>2</sup> every 3 weeks for 6 cycles. The interim activity analysis was planned according to a single…
Is There a Role for Tertiary (TCR) and Quaternary (QCR) Cytoreduction in Recurrent Ovarian Cancer?
2015
BACKGROUND: The aim of the present study was to evaluate the efficacy of tertiary and quaternary cytoreduction in recurrent ovarian cancer patients. PATIENTS AND METHODS:Between January 1997 and December 2014, 53 patients were submitted to cytoreductive surgery for second and third ovarian cancer recurrence at our Unit. RESULTS:Median age at first diagnosis was 48 years (range=20-69). Forty-six patients (86.8%) underwent tertiary cytoreduction. At the time of surgery, isolated and diffuse disease was observed in 48 (90.6%) and 5 (9.4%) patients, respectively. Complete and optimal cytoreduction was obtained in 41 (77.5%) and in 1 (1.9%) patients, respectively. We did not observe any statisti…
S. Typhimurium virulence changes caused by exposure to different non-thermal preservation treatments using C. elegans
2017
The aims of this research study were: (i) to postulate Caenorhabditis elegans (C. elegans) as a useful organism to describe infection by Salmonella enterica serovar Typhimurium (S. Typhimurium), and (ii) to evaluate changes in virulence of S. Typhimurium when subjected repetitively to different antimicrobial treatments. Specifically, cauliflower by-product infusion, High Hydrostatic Pressure (HHP), and Pulsed Electric Fields (PEF). This study was carried out by feeding C. elegans with different microbial populations: E. coli OP50 (optimal conditions), untreated S. Typhimurium, S. Typhimurium treated once and three times with cauliflower by-product infusion, S. Typhimurium treated once and f…
A survival approach for the analysis of cruise passengers’ behavior at the destination
2016
The present work aims at proposing an analysis of cruise passengers’ behavior at the destination through a survival analysis approach. Data collected through GPS devices on cruise passengers’ behavior in the port of Palermo and Dubrovnik are analyzed in order to show similarities and differences among behaviors at the destination, according to socio-demographic characteristics. Results are of interest from both a methodological perspective, related with the processing and the analysis of GPS data, and from the destination management perspective.
Effect of somatic cell count level on functional longevity in Valle del Belice dairy sheep assessed using survival analysis.
2009
The objectives of this study were to evaluate the effect of somatic cell count (SCC) on functional longevity and to estimate the heritability of functional longevity using survival analysis in Valle del Belice dairy sheep. A total of 4,880 lactations of 2,190 ewes from 11 flocks were used. In this study, SCC was considered as an indication of subclinical mastitis. In case of clinical cases, identified by the technicians at milking time, test-day weights and milk samples of those ewes were not considered. Somatic cells were analyzed as counts, without any transformation, and were grouped in 3 classes based on the observed SCC maximum (mxSCC). The mxSCC classes, expressed as 103 cells/mL, wer…
Factors related to the relative survival of patients with diffuse large B-cell lymphoma in a population-based study in France: does socio-economic st…
2017
IF 7.702; International audience; The survival of patients with diffuse large B-cell lymphoma has increased during the last decade as a result of addition of anti-CD20 to anthracycline-based chemotherapy. Although the trend is encouraging, there are persistent differences in survival within and between the USA and European countries suggesting that non-biological factors play a role. Our aim was to investigate the influence of such factors on relative survival of patients with diffuse large B-cell lymphoma. We conducted a retrospective, multicenter, registry-based study in France on 1165 incident cases of diffuse large B-cell lymphoma between 2002 and 2008. Relative survival analyses were p…
Palliative sedation in advanced cancer patients followed at home: A retrospective analysis
2012
Abstract CONTEXT: Data regarding palliative sedation at home in dying patients are lacking. OBJECTIVES: To describe the frequency, indication, and modality of palliative sedation (PS) in patients followed at home. METHODS: A retrospective analysis of home care cancer patients was performed. Patients who received PS before dying were selected and information about epidemiologic characteristics, indications, duration, drugs, and outcomes was collected. RESULTS: Of 370 medical charts of patients who died at home, 49 patients received PS before dying. PS was proposed by the team, relatives, or both in 63.3%, 4.1%, and 32.6% of cases, respectively. Delirium alone or in combination with other sym…
Angiopoietin-2 plasma dosage predicts time to first treatment and overall survival in chronic lymphocytic leukemia.
2010
Abstract The clinical relevance of angiopoietin-2 (Ang2) in chronic lymphocytic leukemia (CLL) was previously suggested by the association between high Ang2, and shorter progression-free survival reported in small series of patients. Here, we evaluated Ang2 glycoprotein levels in plasma samples collected from a multicentric cohort of CLL patients (n = 316) using an enzyme-linked immunosorbent assay method, and we investigated its prognostic role in relation to time to first treatment (TTFT) and overall survival. Based on a cutoff equal to 2459 pg/mL, we divided our cohort in 2 subsets (high and low Ang2) composing 100 (31.6%) and 216 (68.4%) patients, respectively. High Ang2 was predictive …
Preoperative chemoradiotherapy for oesophageal cancer: a systematic review and meta-analysis
2004
Background: The benefit of neoadjuvant chemoradiotherapy in oesophageal cancer has been extensively studied but data on survival are still equivocal. Objective: To assess the effectiveness of chemoradiotherapy followed by surgery in the reduction of mortality in patients with resectable oesophageal cancer. Methods: Computerised bibliographic searches of MEDLINE and CANCERLIT (1970–2002) were supplemented with hand searches of reference lists. Study selection: Studies were included if they were randomised controlled trials (RCTs) comparing preoperative chemoradiotherapy plus surgery with surgery alone, and if they included patients with resectable histologically proven oesophageal cancer wit…
Tubular carcinoma of the breast: Outcome and loco-regional recurrence in 307 patients
2005
Abstract Purpose The aim of this study is to describe the University of Florence experience in evaluating clinical, pathologic and treatment factors as they are related to the outcome and loco-regional recurrence in patients with tubular breast carcinoma. Material and methods Three hundred and seven patients (median age 56.4 years, range 26–91 years) with histological verified tubular carcinoma of the breast were consecutively treated at University of Florence from 1976 to 2001. All patients were followed for a median of 8.4 years (range 3 months to 20 years). Thirty-seven women underwent mastectomy and 270 underwent breast conserving surgery. Positive axillary nodes were found in 15% of pa…
