Abstract 3795
Background
Bevacizumab (bev) is approved in Europe (EU) for first line therapy of OC patients (pts). This study aimed to evaluate the use of Bev in real life, with a focus on toxicity.
Methods
Representative centers in France of French regions and of mode of practice were asked to participate. From 04/13 to 02/15, among the consecutive OC pts treated in each center, were selected those who were newly diagnosed and planned to receive Bev. An independent CRA captured the clinical data at baseline, 6, 12, 18 and 36 months.
Results
A total of 104 centers participated: Private practice (44%), non-academic hospital (31%), academic (11%), anticancer center (14%). 1290 pts were screened, 500 registered and 468 were evaluable. Pts characteristics at baseline were: median age 65 yrs, antihypertensive therapy (26%), anticoagulant (10%), cardiac history (5%), serous histology (83%), interval surgery (47%), complete surgical debulking (74%) and carboplatin-paclitaxel chemotherapy (98%). Only 3.4% were not FIGO stage IIIB-IV. Pts received Bev at 15 mg/kg (80%) during a median of 18 cycles (10-21) and 7.8% stopped treatment for toxicity. Main toxicity was HTA requiring new therapy (38%), PRES (1.3%), venous thrombosis (5%), proteinuria (9.8%) and nephrotic syndrome (2.6%). Other toxicities mostly reported include low grade epistaxis, gingivorrhagia, arthralgia, headache and dysphonia. Gastrointestinal perforation, fistula, arterial events and grade 3-4 bleeding were very low: 0.2%, 0.8%, 0,1% and 0.2% respectively. No pts developed congestive heart failure nor died from toxicity. Median PFS was 17.4 months (IC95% [16.4-19.1]) and % of pts alive at 3 years was 62.4% (IC95 % [58.1-67.1]).
Conclusions
In routine practice among French centers, first-line Bev administration is consistent with the EU label in most of the cases. Efficacy and safety in the real life were in line with that reported in trials excepted for a higher incidence of observed HTA and complications, suggesting the importance of increased education on HTA monitoring.
