An observational, multicenter, retrospective, Italian Sarcoma Group (ISG) study of trabectedin in patients with advanced soft tissue sarcoma (STS).
e23502Background: Trabectedin (T) is approved for patients (pts) with STS after failure of anthracyclines (A) and ifosfamide (I), or pts unsuited to receive AI. ISG performed a retrospective study ...
Abstract A42: miR34a: A valuable indicator of differential outcome of Ewing sarcoma patients with complex functions
Abstract The identification of reliable indicators of prognosis, which may allow the stratification of patients according to different risk at diagnosis isan important aspect of translational research in Ewing sarcoma (ES). In this paper, we validated our previous evidence showing how expression of miR34a in ES tumor samples at diagnosis was signficantly associated with tumor progression (Nakatani F. J Pathol 2012). Here we analyzed a different series of speciments derived from very controlled and homogeneously treated non-metastatic ES patients, and we compared evaluation of miR34a by RT-PCR using frozen samples with that obtained by in situ hybridization on paraffin-embedded samples . The…
Tumor response assessment by Choi criteria in localized high-risk soft tissue sarcoma (STS) treated with chemotherapy (CT): Update at 10-year follow-up of an exploratory analysis on a phase III trial.
11044Background: We already reported (Cancer 2012;118:5857) on better correlation of Choi criteria (Choi) than RECIST with the outcome of pts affected by high-risk STS entering a multicentric Itali...
Trabectedin for patients with advanced soft tissue sarcoma: A non-interventional, retrospective, multicenter study of the italian sarcoma group
The Italian Sarcoma Group performed this retrospective analysis of patients with advanced soft tissue sarcoma, pretreated with ≥1 anthracycline-based treatment, and treated with trabectedin every three weeks. Primary endpoint was to describe real-life use of trabectedin across Italy. Secondary endpoints included objective response rate (ORR) and safety. Overall, 512 patients from 20 Italian centers were evaluated. Leiomyosarcoma (37.7%)/liposarcoma (30.3%) were the most prevalent histological types (abbreviated as L-sarcoma). Patients received a median of four trabectedin cycles (range: 1–40), mostly as a second-line treatment (~60% of patients). The ORR was 13.7% superior (p <
High-risk soft tissue sarcomas treated with perioperative chemotherapy: Improving prognostic classification in a randomised clinical trial
Background: Patients with extremity and trunk wall soft tissue sarcoma (STS) with high malignancy grade and size >5 cm are at high-risk of death. This risk varies depending also on other patient and tumour features, including histologic subtype. This study investigated whether a prognostic nomogram can improve risk assessment of these patients. Methods: Data from high-risk STS patients enrolled in a randomised controlled trial investigating different perioperative chemotherapy regimens were analysed. Ten-year probability of overall survival (OS) and incidence of distant metastasis (DM) were computed using the prognostic nomogram Sarculator (pr-OS and inc-DM, respectively). Tumour response a…
Biological indicators of prognosis in Ewing's sarcoma: An emerging role for lectin galactoside-binding soluble 3 binding protein (LGALS3BP)
Starting from an experimental model that accounts for the 2 most important adverse processes to successful therapy of Ewing's sarcoma (EWS), chemoresistance and the presence of metastasis at the time of diagnosis, we defined a molecular signature of potential prognostic value. Functional annotation of differentially regulated genes revealed 3 major networks related to cell cycle, cell-to-cell interactions and cellular development. The prognostic impact of 8 genes, representative of these 3 networks, was validated in 56 EWS patients. High mRNA expression levels of HINT1, IFITM2, LGALS3BP, STOML2 and c-MYC were associated with reduced risk to death and lower risk to develop metastasis. At mul…
The sarculator stratified prognosis of patients with high-risk soft tissue sarcomas (STS) of extremities and trunk wall treated with perioperative chemotherapy in a randomised controlled trial (RCT).
11016 Background: Patients with extremity and trunk wall STS with high malignancy grade and size larger than 5cm are considered at high risk of death, but in fact this risk varies broadly depending on histologic subtype and size. The Sarculator, a nomogram for STS, can improve prognostic assessment of these patients. This tool was evaluated for stratifying risk of distant metastasis (DM) and overall survival (OS) in a RCT investigating perioperative chemotherapy. Methods: High-risk STS patients were randomly assigned to receive either three cycles of preoperative chemotherapy with epirubicin (120 mg/m2) and ifosfamide (9 g/m2) or the same three preoperative cycles followed by two further p…
Expression of insulin-like growth factor system components in Ewing's sarcoma and their association with survival.
Abstract Aims The role of IGF system in the pathogenesis of Ewing’s sarcoma (EWS) is well-documented. However, still little information is available about the value of IGF system components as indicators of prognosis. Understanding the clinical role for IGF system in EWS patients may be important because different subtypes of patients have distinct outcome and may require different treatment protocol. We evaluated the expression of insulin-like growth factor (IGF)-receptor (IGF-IR), insulin receptor (IR), IGF-I and some major intracellular mediators (IRS1, p-ERK) in specimens from EWS patients with primary localised untreated tumours. Patients and methods 290 samples were used for immunohis…
The Nasal Epithelium as a Factory for Systemic Protein Delivery
We have previously shown that recombinant Sendai virus (SeV) produces efficient in vivo airway epithelial gene transfer. The ability to produce therapeutic levels of circulating proteins following noninvasive gene transfer would have widespread clinical application. Here, we compared nose, lung, and skeletal muscle for the ability to produce circulating levels of the secreted mouse antiinflammatory cytokine interleukin-10 (IL10) following SeV-mediated gene transfer. High levels of serum IL10 were obtained from each site with a potency order of lung > nose > muscle for a given viral titer. Serum levels from each site were within the likely required range for anti-inflammatory effects. The co…
