RT Journal Article SR Electronic T1 Platinum–Vinorelbine Induction Chemotherapy plus Bevacizumab With and Without Pemetrexed Switch Maintenance in Advanced NSCLC JF Anticancer Research JO Anticancer Res FD International Institute of Anticancer Research SP 6255 OP 6259 VO 35 IS 11 A1 MICHELSEN, LINDA A1 SØRENSEN, JENS BENN YR 2015 UL http://ar.iiarjournals.org/content/35/11/6255.abstract AB Background: Little information is available until today regarding the effect of platinum-doublet chemotherapy with bevacizumab followed by pemetrexed as a sole maintenance treatment. Original data concerns different induction regimens plus bevacizumab with bevacizumab maintenance to progression in advanced non-squamous non-small cell lung cancer (NSCLC). Patients and Methods: Two consecutive groups of patients with advanced non-squamous NSCLC received carboplatin, vinorelbine and bevacizumab for four cycles. Group A (2010-2012) did not receive any maintenance therapy, whereas group B (2012-2013) received pemetrexed switch maintenance (500 mg/m2) every three weeks until disease progression. Results: The median progression-free survival (PFS) was 4.4 months and 7.3 months (p<0.001) and one-year survival was 42% and 52% for Group A (n=20) and B (n=22) patients, respectively. Disease control rates were 65% and 86% (p=0.104). Deep venous thrombosis and pulmonary embolism occurred in three (15%) and seven (32%) patients in group A and B, respectively. Conclusion: The inferior PFS (p<0.001) without maintenance suggests that induction treatment including bevacizumab should not be planned without subsequent maintenance treatment. Whether it is better to use pemetrexed or bevacizumab, or a combination of both, as maintenance therapy is not yet established.
