Background Trabectedin and pegylated liposomal doxorubicin (PLD) is an effective combination therapy for platinum-sensitive recurrent ovarian cancer (ROC), particularly for disease relapsing within 6-12 months of platinum therapy. The non-interventional PROSPECTYON study evaluated trabectedin/PLD in French clinical practice. Patients and methods Patients with ROC after at least one platinum-based regimen received 1.1 mg/m2 trabectedin plus 30 mg/m2 PLD every 3 weeks. Efficacy and safety were evaluated in subgroups according to platinum-free interval [6-12 versus ≥12 months (partially or fully platinum sensitive, respectively)]. Results Recurrent disease was partially platinum-sensitive in 58 patients and fully sensitive in 33 patients treated between July 2014 and June 2016. Patients in both subgroups received a median of six cycles of trabectedin and PLD. The most common grade 3 or more toxicities were haematological. Median progression-free survival was 6 months for both subgroups. Conclusion Trabectedin/PLD is a valuable treatment option for partially or fully platinum-sensitive ROC.

The present monocentric and prospective phase 1 study evaluated the safety of a metronomic chemotherapy in refractory tumors.Patients with advanced solid cancer refractory to standard therapy received a combination of low-dose vinorelbine, cyclophosphamide and interferon-alpha. A dose escalation model with 3 levels was planned. The primary end-point was safety and tolerability, secondary end-points were treatment continuation rate at 4 months, progression-free survival (PFS), overall survival (OS), radiological assessment (MRI) of anti-angiogenic effect.Thirty patients were enrolled. No dose-limiting toxicity was observed. All but two adverse events were toxicities of grade 1-2. Treatment continuation rate at 4 months was 6.67% (2 out of 30 patients). Median PFS and OS were 1.6 and 6.1 months. Exploratory MRI analyses related to anti-angiogenic effect did not show any relevant modification.This combination of metronomic chemotherapy is well-tolerated and deserves to be deeply explored in refractory solid tumors.
