NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines

The purpose of this article is to provide updated recommendations for the treatment of patients with stage IV non–small-cell lung cancer. A literature search identified relevant randomized trials published since 2002. The scope of the guideline was narrowed to chemotherapy and biologic therapy. An Update Committee reviewed the literature and made updated recommendations. One hundred sixty-two publications met the inclusion criteria. Recommendations were based on treatment strategies that improve overall survival. Treatments that improve only progression-free survival prompted scrutiny of toxicity and quality of life. For first-line therapy in patients with performance status of 0 or 1, a platinum-based two-drug combination of cytotoxic drugs is recommended. Nonplatinum cytotoxic doublets are acceptable for patients with contraindications to platinum therapy. For patients with performance status of 2, a single cytotoxic drug is sufficient. Stop first-line cytotoxic chemotherapy at disease progression or after four cycles in patients who are not responding to treatment. Stop two-drug cytotoxic chemotherapy at six cycles even in patients who are responding to therapy. The first-line use of gefitinib may be recommended for patients with known epidermal growth factor receptor (EGFR) mutation; for negative or unknown EGFR mutation status, cytotoxic chemotherapy is preferred. Bevacizumab is recommended with carboplatin-paclitaxel, except for patients with certain clinical characteristics. Cetuximab is recommended with cisplatin-vinorelbine for patients with EGFR-positive tumors by immunohistochemistry. Docetaxel, erlotinib, gefitinib, or pemetrexed is recommended as second-line therapy. Erlotinib is recommended as third-line therapy for patients who have not received prior erlotinib or gefitinib. Data are insufficient to recommend the routine third-line use of cytotoxic drugs. Data are insufficient to recommend routine use of molecular markers to select chemotherapy.

American Society of Clinical Oncology Clinical Practice Guideline Update on Chemotherapy for Stage IV Non–Small-Cell Lung Cancer

In 2010, approximately 222,520 new cases of lung or bronchial cancer will be diagnosed in the USA, and 157,300 patients are expected to die of this disease [1]. Lung cancer is the leading cause of cancer-related death in both men and women, and non-small cell lung cancer (NSCLC) accounts for about 80 % of these cases. Lung cancer is most often asymptomatic in its early stages; consequently, the disease is usually diagnosed at an advanced stage, when it is much more difficult to treat. One or more genes are believed to be responsible for an inherited increase in risk of developing lung cancer in the general population. Smoking remains one of the main environmental factors associated with the development of lung cancer [2]. Although the development of lung cancer seems to be the result of several sequential molecular abnormalities in individuals at high risk of developing the disease, the genetic mechanisms by which an individual develops lung cancer remain largely unknown. These steps involve abnormalities in the expression of angiogenic factors (e.g., vascular endothelial growth factor, or VEGF and epithelial growth factor receptors, or EGFRs) [3]. The heterogeneity of lung cancer and the diversity of its morphologic appearance and molecular properties make the application of molecular targeted therapies used in other cancers more complex, but such therapies are certainly a goal for the future.

Non–Small Cell Lung Cancer

Neuroendocrine tumors account for approximately 20% of lung cancers; most (≈15%) are small cell lung cancer (SCLC). These NCCN Clinical Practice Guidelines in Oncology for SCLC focus on extensive-stage SCLC because it occurs more frequently than limited-stage disease. SCLC is highly sensitive to initial therapy; however, most patients eventually die of recurrent disease. In patients with extensive-stage disease, chemotherapy alone can palliate symptoms and prolong survival in most patients; however, long-term survival is rare. Most cases of SCLC are attributable to cigarette smoking; therefore, smoking cessation should be strongly promoted.
