Abstract:
Non-small cell lung cancer (NSCLC) is the leading cause of cancer death in the United States and throughout the world. This is largely because more than half of lung cancer cases present as metastatic disease, making local therapy for cure impossible. The last decade has seen significant improvement in first-line treatment of NSCLC, including the use of new chemotherapeutic agents with more effective therapeutic profiles. However, standard cytotoxic regimens are still limited and it remains critical to better understand and develop new treatment options for refractory disease. This has included some new second-line therapeutic approaches and has led to a focus on molecular targeted therapy, including agents that block the epidermal growth factor receptor (EGFR) or angiogenesis. EGFR-targeted agents such as gefitinib, erlotinib, and cetuximab have been successfully used for NSCLC treatment, with studies reporting overall response rates of 18.4%, 8.9%, and 3.3%, respectively. Angiogenesis inhibitors such as bevacizumab and ZD6474 have also improved treatment outcome. Bevacizumab had an overall response rate of 27% when used in combination with paclitaxel and carboplatin, and ZD6474 had an overall response rate of 26% when used in combination with docetaxel. Using these compounds alone or in combination may improve the survival and quality of life of patients with lung cancer in the refractory setting.
Insights
New targeted therapies show promise for advanced non-small cell lung cancer (NSCLC). Agents blocking EGFR or angiogenesis offer improved outcomes for patients with refractory disease.
Area of Science:
- Oncology
- Medical Science
Background:
- Non-small cell lung cancer (NSCLC) is a leading cause of cancer mortality globally.
- Metastatic disease at diagnosis limits curative local treatment options for over half of NSCLC patients.
- Current standard cytotoxic chemotherapy for NSCLC has limitations, necessitating novel approaches for refractory cases.
Purpose of the Study:
- To review advancements in NSCLC treatment, focusing on molecular targeted therapies.
- To evaluate the efficacy of epidermal growth factor receptor (EGFR) inhibitors and angiogenesis inhibitors in refractory NSCLC.
- To assess the potential of these targeted agents in improving survival and quality of life.
Main Methods:
- Literature review of recent clinical studies on NSCLC treatment.
- Analysis of response rates for EGFR-targeted agents (gefitinib, erlotinib, cetuximab).
- Evaluation of outcomes for angiogenesis inhibitors (bevacizumab, ZD6474) in combination regimens.
Main Results:
- EGFR inhibitors demonstrated overall response rates of 18.4% (gefitinib), 8.9% (erlotinib), and 3.3% (cetuximab).
- Angiogenesis inhibitors showed promise: bevacizumab (27% response rate with paclitaxel/carboplatin) and ZD6474 (26% response rate with docetaxel).
- These targeted therapies represent significant progress in managing advanced and refractory NSCLC.
Conclusions:
- Molecular targeted therapies, including EGFR and angiogenesis inhibitors, offer new avenues for treating refractory NSCLC.
- Combination strategies involving these agents may enhance patient survival and quality of life.
- Continued research into targeted therapies is crucial for improving outcomes in NSCLC.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy.
