A Real-Life Experience of Bevacizumab in Elderly Women With Advanced Ovarian Carcinoma.

ABSTRACT

OBJECTIVE: This study aimed to assess the tolerance of bevacizumab (BEVA) among older ovarian cancer patients in daily clinical practice and identify a subpopulation of patients with a high risk of severe adverse effects. METHODS: Consecutive patients with a pathologically proven high-grade serous ovarian, tubal, or peritoneal carcinoma who received BEVA between January 2006 and June 2014 were included in a retrospective analysis. RESULTS: Among 86 BEVA-treated patients, 42 (48.8%) received concomitant chemotherapy, 26 (30%) had baseline arterial hypertension (HTN), and 33 (38.4%) were considered elderly (>70 years). Incidence of arterial, venous thromboembolism, hemorrhage, and bowel perforation were 2%, 8%, 12%, and 0%, respectively, and was not related to age. Incidence of severe (NCI-CTC v4 G3-4) HTN was significantly higher in elderly patients than in younger ones (39%; 95% confidence interval [CI], 22%-56% vs 17%; 95% CI, 7%-27%) (P = 0.017 by χ test) and in patients with baseline HTN (P < 0.05). Twenty-three percent of younger patients had baseline HTN compared with 42% of older ones (P = 0.052). Among patients without baseline HTN, older age was not associated with increased risk of severe HTN. However, incidence of severe HTN reached 71% (95% CI, 47%-95%) in older patients with baseline HTN. Exploratory analysis indicates that progression-free survival was similar in younger and older patients. CONCLUSIONS: Bevacizumab is feasible in patients older than 70 years with advanced ovarian carcinoma. More attention must be paid to elderly patients with baseline HTN.
