21 Palliative Care and End-of-life Decisions For patients with advanced-stage disease, be realistic about the poor prognosis from the beginning. Emphasize that advanced-stage NSCLC can be treated, even though cure is unlikely. Advances in chemotherapy and palliative care have extended good-quality life for most patients. Early palliative care not only makes patients more comfortable but can extend life. Encourage participation in clinical trials. Maintain a healthy balance between optimism and realism.

22 SUMMARY Early diagnosis has the greatest impact on survival in NSCLC. The 5-year survival for NSCLC is directly related to stage at diagnosis, ranging from 80% at stage 1 to <10% at stage IV. The National Lung Screening Trial showed that lowdose radiation CT can reduce lung cancer mortality compared with standard x-ray in high-risk patients. Widespread adoption of low-dose CT for lung cancer screening has been complicated by unresolved questions related to cost, a high rate of false-positive results, and uncertainty about the target population for screening.

23 SUMMARY (cont d) Once largely ignored as a component of lung cancer treatment, chemotherapy has evolved into an essential part of treatment for many patients. The evolution of targeted therapies has led to incremental improvement in survival for NSCLC, beyond that achieved with conventional chemotherapy. Identification of generic mutations in tumors has increased the potential for individualized or personalized treatment of NSCLC. Tumors with specific types of mutations have demonstrated increased sensitivity to drugs that target those mutations.

24 SUMMARY (cont d) Incremental improvement in survival achieved with chemotherapy and targeted drugs has led to substantial improvement in survival for patients with NSCLC. End-of-life discussions should be initiated early in patients with advanced-stage NSCLC and become a part of ongoing decision making about patient care. Early implementation of palliative care not only can improve patients comfort and quality of life but extend survival in some cases. Clinicians should help patients and families maintain an appropriate balance between hope for patients with NSCLC and the realities of the disease.
