to paclitaxel/carboplatin, prolongs survival in previously untreated patients with advanced non-small-cell lung cancer: preliminary results from the ECOG Lung Cancer: Secondary Analyses of the ECOG and PointBreak Trials. Eastern Cooperative Oncology Group (E) and PointBreak studies. ECOG demonstrated longer progression-free (PFS) and overall survival ( OS) with the addition of bevacizumab at a dose of 15 mg/m2.

Given the associated cost and toxicity however, optimizing the patient-population exposed to these agents remains a high priority.

A number of other anti-angiogenic agents have been investigated in advanced stage NSCLC without success. Both bevacizumab and pemetrexed can be administered as maintenance and it will be crucial to determine if both the drugs together truly outperform the individual drugs in that setting.

They also conclude that bevacizumab showed greater efficacy in patients with adenocarcinoma, and lower body weight loss, but detected no apparent interaction of the treatment effect with age. The broad conclusion that bevacizumab can be added to doublet chemotherapy with a survival benefit seems exaggerated, given that only two specific doublets were examined, one in patients who would no longer be offered the drug i.

The effect of bevacizumab on lower stage disease similarly remains unclear.

Of greater clinical interest has been the interaction of pemetrexed with bevacizumab. The meta-analysis was, therefore, based on the reported summary data, both 459 and within subgroups.

ECOG will continue to dominate current treatment recommendations and the only evidence-based regimen to which bevacizumab should reasonably be added as a standard remains carboplatin and paclitaxel.

Rapid chemotherapy-induced actue endothelial progenitor cell mobilization: Evidence-based role of bevacizumab in non-small cell lung cancer E. Palliative chemotherapy improves the quality of life and prolongs survival in patients with metastatic non-small-cell lung cancer NSCLC. Its precise contribution to increasing survival eccog unclear. When attempting to integrate bevacizumab with radiation complications included tracheoesophageal fistula with fatal hemoptysis and this approach is not being pursued.

Oxford University Press is 45599 department of the University of Oxford. Furthermore, given the mutually exclusive indications for gemcitabine based on activity and bevacizumab based on toxicitythis combination is of no clinical interest in advanced stages although there may be a role for bevacizumab with gemcitabine in resected patients where tumor-related bleeding is of less concern.

Nevertheless, it suggests that the addition of bevacizumab to paclitaxel-based 459 chemotherapy since its approval in the United States has not led to improved survival data in this Medicare population. Analyzed separately, these trials support the administration of bevacizumab with carboplatin and paclitaxel, while its administration with gemcitabine underperforms for the survival end point and is not clinically relevant since gemcitabine is preferentially given to patients with squamous cell histology who are poor candidates for bevacizumab due to risk of pulmonary hemorrhage.

Thus, the trial investigated the addition of bevacizumab to a sub-optimal doublet base for its target patient population. It has also been investigated in multiple other solid tumors and is part of standard therapy in colorectal cancer, gliomas and renal cell cancer. N Engl J Med.

Randomized phase II study of first-line carboplatin-paclitaxel with or without bevacizumab in Japanese patients with advanced non-squamous non-small-cell lung cancer. Of interest, Zhu et al. Receive exclusive offers and updates ecob Oxford Academic.

Vandetanib plus pemetrexed for the second-line treatment of advanced non-small-cell lung cancer: Citing articles via Web of Science Subset analysis suggested that older patients derived no benefit from the addition of bevacizumab [ 10 ].

Paclitaxel-carboplatin alone or with bevacizumab for non-small-cell lung cancer.

Preclinical data indicate that paclitaxel might be more susceptible to positive modulation by bevacizumab [ 17 ]. Three of the trials used a paclitaxel Taxol -based regimen and one used gemcitabine. Outcomes for elderly, advanced-stage non-small-cell lung cancer patients treated with bevacizumab in combination with carboplatin and paclitaxel: The overall marginally positive statistical survival data reported by the authors are most likely explained by the fact that the large paclitaxel-based trial ECOG is not fundamentally disturbed by the less positive gemcitabine trial AVAiLwhile the two smaller paclitaxel-based studies contribute only marginally to the overall results.

However, a majority of patients do not have this option and continue to be offered standard doublet chemotherapy.

Paclitaxel-carboplatin alone or with bevacizumab for non-small-cell lung cancer.

The addition of bevacizumab to paclitaxel plus carboplatin in the treatment of selected patients with non-small-cell lung cancer has a significant survival benefit with the risk of increased treatment-related deaths. Phase III study of carboplatin and paclitaxel alone or with sorafinib in advanced non-small-cell lung cancer. Should older patients be treated with bevacizumab? This strategy has been only marginally successful. In that case, the doublet would likely be more tolerable and cost-effective.

Karrison; Evidence-based role of bevacizumab in non-small cell lung cancer, Annals of OncologyVolume 24, Issue 1, 1 JanuaryPages 6—9, https: The optimal dose of bevacizumab also remains unclear, although the ECOG trial using the higher dose was the only trial to show significant improvement in survival.

However, until data provide evidence to the contrary it can be ecoy that a 5499 doublet would be equivalent to the carboplatin, paclitaxel, bevacizumab triplet [ 115 ].

The addition of bevacizumab to pemetrexed remains of some interest. This would tend to push both HRs toward one. Patients on 44599 study arms continued with maintenance therapy either bevacizumab alone or bevacizumab and pemetrexed.

Is the conclusion that bevacizumab added to any platinum-based chemotherapy prolongs survival supported by these data?
