Trabectedin for patients with advanced soft tissue sarcoma: A non-interventional, retrospective, multicenter study of the italian sarcoma group

2021

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 &lt

Human equilibrative nucleoside transporter 1 as a predictor of efficacy to gemcitabine in angiosarcoma and leiomyosarcoma.

Human equilibrative nucleoside transporter 1 gene expression is associated with gemcitabine efficacy in advanced leiomyosarcoma and angiosarcoma

2017

Background: The expression of human equilibrative nucleoside transporter 1 (hENT1), the major gemcitabine transporter into cells, has been thoroughly investigated as a predictive marker of response to gemcitabine in pancreatic cancer and biliary tract cancers. Since gemcitabine is widely used in the treatment of leiomyosarcoma and angiosarcoma, we investigated the correlation between hENT1 expression and gemcitabine efficacy in these sarcoma subtypes.Methods: We retrospectively identified 71 patients affected by advanced angiosarcoma (26) or leiomyosarcoma (45) treated within five Italian referral centres for sarcoma; among them, 49 patients (15 angiosarcoma, 34 leiomyosarcoma) were treated…

Role of Microbiota in development, gene expression and epigenetic modifications in D. melanogaster host model

Eukaryotes and prokaryotes have developed mutually beneficial relationships over millennia of evolutionary adaptation. Recent observations suggest a strong correlation between the presence of Microbiota and host homeostasis, but little is known about the mechanisms they use to shape the physiology and to reprogram gene expression of their host. Using both conventionally reared and germ-free D. melanogaster as a model system, I found a role of bacteria in host protein expression and development, as germ-free flies develop more slowly than their conventional counterpart. Remarkably, using the classic variegated In(1)wm4 inversion, I identified a role of Microbiota as modifier of white Positio…
