Abstract Text

Doxorubicin and trabectedin are considered active drugs in soft tissue sarcoma (STS). The combination of both drugs was hypothesized to be advantageous and safe on the basis of preclinical evidence and a previous phase I trial, respectively. The aim of this study was to compare the clinical outcome of trabectedin plus doxorubicin with doxorubicin as first-line treatment of advanced STS patients.In this open-label randomized phase II trial, the main end point was progression-free survival (PFS). Trabectedin 1.1 mg/m(2) in a 3-hour infusion plus doxorubicin 60 mg/m(2) as the experimental arm and doxorubicin 75 mg/m(2) as the control arm were administered for up to six cycles. Translational research was planned to correlate the expression of apoptotic and DNA repair genes with clinical outcome.In 115 randomly assigned patients, the median PFS was 5.5 months in the control arm and 5.7 months in the experimental arm (hazard ratio, 1.16; 95% CI, 0.79 to 1.71; P = .45) in the intent-to-treat analysis. The trial was stopped for futility after the interim analysis, because the results in the experimental arm showed the risk reduction for the main end point to be < 9.64%. The proportion of patients with grade 3 or 4 thrombocytopenia, asthenia, and liver toxicity was significantly higher in the experimental arm. FAS and p53 were shown to be prognostic factors for PFS (7.0 months if FAS+ and p53-; 3.4 months if FAS+/p53+ or FAS-/p53-; and 0.7 months if FAS- and p53+; P < .001) and for overall survival.Trabectedin plus doxorubicin did not show superiority over doxorubicin alone as first-line treatment of advanced STS. The prognostic role of apoptotic key genes, FAS and p53, was shown to be robust enough to continue this research line.

Filtering

Case insensitive filtering will display rows if any text in any cell matches the filter term
Use simple literal full or partial string matches
Separate multiple filter terms with a space. Any order may be used (i. e. a b c and c b a are equivalent )
Filtering will only apply to rows that are already loaded on the page. Filtering has no impact on query parameters.
Use quotes to match on a longer phrase with spaces (i.e. "mtor c1483f")

Sorting

Generally, the default sort order for tables is set to be first column ascending; however, specific tables may set a different default sort order.
Click on any column header arrows to sort by that column
Hold down the Shift key and click multiple columns to sort by more than one column. Be sure to set ascending or descending order for a given column before moving on to the next column.
