P2.01-071 - TULUNG REGISTRY: Data Analysis of Patients with Non-Squamous NSCLC Treated with Bevacizumab in the Czech Republic (ID 2934)
09:30 - 09:30 | Author(s): M. Hrnciarik
- Abstract
Background:
We conducted a systematic review of data from patients reported in the TULUNG registry (data cut-off 26-Jan-15). The TULUNG registry is Czech national oncology registry which prospectively collects data from all NSCLC patients treated with new targeted therapies in Czech Republic since 2008.
Methods:
Analysis was performed on a group of patients with non-squamous NSCLC with good performance status (PS 0-2), treated with bevacizumab. Since 2008 bevacizumab has been used for treatment in 193 patients (full record criteria met). 10 patients with incomplete records were not included to the review
Results:
In this group of patients 35.8% were female; the median age at bevacizumab treatment initiation was 60 years (range 29-83). The majority of patients were smokers and ex-smokers (37.8% and 34.7% respectively) and 91.7% of tumors were adenocarcinomas by histology. 91.7% patients were at the metastatic stage at the initiation of bevacizumab treatment, 6.2% of patients were in stage IIIb and only 2.1% of patients in stage IIIa (UICC6). The performance status was distributed between ECOG PS0 and PS1 mainly (40.9% PS0 and 58% PS1)at the initiation of the bevacizumab treatment. Majority of patients received bevacizumab treatment in the first line (96.4%). Two main chemotherapy regimens were used; carboplatin+paclitaxel (68.4%) and cisplatin+gemcitabine (9.8%). In this group of 193 patients analyzed, bevacizumab therapy was terminated in 152 (78.8%) patients at data cut-off. The most frequent reasons for termination were disease progression, in 55.9%, termination of treatment according to plan in 8.6% and death, in 7.9% of patients. Treatment with bevacizumab is ongoing in 41 (21.2%) patients. In 152 of patients with terminated treatment, the median duration of treatment was 15.6 weeks (95% CI 0.3 – 51.3). Response assessment showed CR in 0.7%, PR in 40.8% and SD in 35.5% of patients. Median progression free survival was 6.9 months (95% CI 5.8 – 8.1), median overall survival 16.7 months (95% CI 11.7 – 21.7). 1-year survival from bevacizumab treatment initiation was 67.9%. Adverse events were reported in 9.8% of patients, the most frequently reported adverse events were thromboembolic events (5.2%) and neutropenia (1.6%). Tromboembolic events were observed in 10 patients, none of these was fatal. We didn´t observe any severe episode of bleeding event.
Conclusion:
Therapy with bevacizumab in non-squamous NSCLC was active and very well tolerated. In eligible patients, only 7 patients (4.6%) had to discontinue bevacizumab therapy due to safety reasons. In patients with completed bevacizumab therapy 77.0% disease control rate was reached with a median survival of approximately 16.7 months from initiation of first line therapy with bevacizumab.
