Résumé
The addition of trabectedin to doxorubicin, followed by trabectedin maintenance, may have superior efficacy to doxorubicin alone as first-line treatment in patients with advanced leiomyosarcoma. We conducted a phase 3 trial involving patients with metastatic or unresectable leiomyosarcoma who had not received chemotherapy previously. Patients were randomly assigned to receive either single-agent doxorubicin (six cycles) or doxorubicin plus trabectedin (six cycles), with continued trabectedin as maintenance therapy in patients in the doxorubicin-trabectedin group who did not have disease progression. Surgery to resect residual disease was allowed in each group after six cycles of therapy. Analyses of progression-free survival (primary end point) and overall survival (secondary end point) were adjusted for two stratification factors: tumor origin site (uterine vs. soft tissue) and disease stage (locally advanced vs. metastatic). The primary end-point results were reported previously. A total of 150 patients underwent randomization. At a median follow-up of 55 months (interquartile range, 49 to 63), a total of 107 patients had died (47 in the doxorubicin-trabectedin group and 60 in the doxorubicin group). The median overall survival was longer in the doxorubicin-trabectedin group (33 months; 95% confidence interval [CI], 26 to 48) than in the doxorubicin group (24 months; 95% CI, 19 to 31); the adjusted hazard ratio for death was 0.65 (95% CI, 0.44 to 0.95). In a finding consistent with earlier reports, progression-free survival was longer in the doxorubicin-trabectedin group (12 months; 95% CI, 10 to 16) than in the doxorubicin group (6 months; 95% CI, 4 to 7); the adjusted hazard ratio for progression or death was 0.37 (95% CI, 0.26 to 0.53). The incidence of adverse events and the percentage of patients with dose reductions were higher with doxorubicin plus trabectedin than with doxorubicin alone. Combination therapy with doxorubicin and trabectedin induction, followed by trabectedin maintenance, was associated with improved overall survival and progression-free survival, as compared with doxorubicin alone, among patients with metastatic or surgically unresectable uterine or soft-tissue leiomyosarcoma.

METHODS

Surgery to resect residual disease was allowed in each group after six cycles of therapy.

At a median follow-up of 55 months (interquartile range, 49 to 63), a total of 107 patients had died (47 in the doxorubicin-trabectedin group and 60 in the doxorubicin group).
