Abstract:
The introduction of targeted therapies since a few years has led to the rapid growth of biological agent use in oncology. Nevertheless, they are not available for all the categories of tumors. Moreover, the latest monoclonal antibody, bevacizumab, is currently only used at an early stage of the disease. Two new types of indications which are not yet admitted are emphasized in this review. The first one is the combination of bevacizumab and cetuximab in refractory metastatic colorectal cancer. The second one is the addition of bevacizumab to chemotherapy in metastatic tumors previously treated but still sensitive to chemotherapy. The collect of numerous observational studies is needed to bring evidence of efficacy and to justify the rapid use of these costly treatments for more patients.
Insights
Targeted therapies like bevacizumab are expanding in oncology but have limitations. This review explores new uses for bevacizumab in advanced colorectal cancer and previously treated metastatic tumors, requiring further studies.
Area of Science:
- Oncology
- Pharmacology
Context:
- Targeted therapies and biological agents are increasingly used in cancer treatment.
- Current limitations exist for targeted therapies across all tumor types.
- Bevacizumab, a monoclonal antibody, is primarily used in early-stage disease.
Purpose:
- To review emerging indications for bevacizumab in oncology.
- To highlight the potential of combining bevacizumab with cetuximab in refractory metastatic colorectal cancer.
- To explore the addition of bevacizumab to chemotherapy for sensitive, previously treated metastatic tumors.
Summary:
- Bevacizumab's application is expanding beyond early-stage disease.
- Investigating bevacizumab and cetuximab combination for refractory metastatic colorectal cancer.
- Evaluating bevacizumab plus chemotherapy for sensitive, pre-treated metastatic cancers.
Impact:
- Further observational studies are needed to establish efficacy for new bevacizumab indications.
- Evidence generation is crucial for the wider adoption of these potentially life-extending treatments.
- Cost-effectiveness and patient access to advanced cancer therapies are key considerations.
