Postoperative Radiotherapy for Stage II or III Non–Small-Cell Lung Cancer Using the Surveillance, Epidemiology, and End Results Database

PURPOSE To investigate the association between survival and postoperative radiotherapy (PORT) in patients with resected non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Within the Surveillance, Epidemiology, and End Results database, we selected patients with stage II or III NSCLC who underwent a lobectomy or pneumonectomy. Only those patients coded as receiving PORT or observation were included. To account for perioperative mortality, we excluded patients who survived less than 4 months. As a result of our inclusion criteria, we selected a total of 7,465 patients, with a median follow-up time of 3.5 years for patients still alive. RESULTS Predictors for the use of PORT included age less than 50 years, higher American Joint Committee on Cancer stage, T3-4 tumor stage, larger tumor size, advanced node stage, greater number of lymph nodes involved, and a ratio of lymph nodes involved to lymph nodes sampled approaching 1.00. On multivariate analysis, older age, T3-4 tumor stage, N2 node stage, male sex, fewer sampled lymph nodes, and greater number of involved lymph nodes had a negative impact on survival. The use of PORT did not have a significant impact on survival. However, in subset analysis for patients with N2 nodal disease (hazard ratio [HR] = 0.855; 95% CI, 0.762 to 0.959; P = .0077), PORT was associated with a significant increase in survival. For patients with N0 (HR = 1.176; 95% CI, 1.005 to 1.376; P = .0435) and N1 (HR = 1.097; 95% CI, 1.015 to 1.186; P = .0196) nodal disease, PORT was associated with a significant decrease in survival. CONCLUSION In a population-based cohort, PORT use is associated with an increase in survival in patients with N2 nodal disease but not in patients with N1 and N0 nodal disease.

Symptom Management in Patients With Lung Cancer : Diagnosis and Management of Lung Cancer, 3rd ed: American College of Chest Physicians Evidence-Based Clinical Practice Guidelines

BACKGROUND Many patients with lung cancer will develop symptoms related to their disease process or the treatment they are receiving. These symptoms can be as debilitating as the disease progression itself. To many physicians these problems can be the most difficult to manage. METHODS A detailed review of the literature using strict methodologic review of article quality was used in the development of this article. MEDLINE literature reviews, in addition to Cochrane reviews and other databases, were used for this review. The resulting article lists were then reviewed by experts in each area for quality and finally interpreted for content. RESULTS We have developed recommendations for the management of many of the symptom complexes that patients with lung cancer may experience: pain, dyspnea, airway obstruction, cough, bone metastasis, brain metastasis, spinal cord metastasis, superior vena cava syndrome, hemoptysis, tracheoesophageal fistula, pleural effusions, venous thromboembolic disease, depression, fatigue, anorexia, and insomnia. Some areas, such as dyspnea, are covered in considerable detail in previously created high-quality evidence-based guidelines and are identified as excellent sources of reference. The goal of this guideline is to provide the reader recommendations based on evidence supported by scientific study. CONCLUSIONS Improved understanding and recognition of cancer-related symptoms can improve management strategies, patient compliance, and quality of life for all patients with lung cancer.

The risk of death from heart disease in patients with nonsmall cell lung cancer who receive postoperative radiotherapy: analysis of the Surveillance, Epidemiology, and End Results database.

This study was designed to investigate whether the mortality from heart disease, a manifestation of intercurrent disease after postoperative radiotherapy (PORT), has decreased over time for patients with nonsmall cell lung cancer (NSCLC).

The role of radiosurgery to the tumor bed after resection of brain metastases.

BACKGROUND Optimal postoperative management paradigm for brain metastases remains controversial. OBJECTIVE To conduct a systematic review of the literature to understand the role of postoperative stereotactic radiosurgery after resection of brain metastases. METHODS We performed a MEDLINE search of the literature to identify series of patients with brain metastases treated with stereotactic radiosurgery after surgical resection. Outcomes including overall survival, local control, distant intracranial failure, and salvage therapy use were recorded. Patient, tumor, and treatment factors were correlated with outcomes through the use of the Pearson correlation and 2-way Student t test as appropriate. RESULTS Fourteen studies involving 629 patients were included. Median survival for all studies was 14 months. Local control was correlated with the median volume treated with radiosurgery (r = -0.766, P < .05) and with the rate of gross total resection (r = .728, P < .03). Mean crude local control was 83%; 1-year local control was 85%. Distant intracranial failure occurred in 49% of cases, and salvage whole-brain radiation therapy was required in 29% of cases. Use of a radiosurgical margin did not lead to increased local control or overall survival. CONCLUSION Our systematic review supports the use of radiosurgery as a safe and effective strategy for adjuvant treatment of brain metastases, particularly when gross total resection has been achieved. With all limitations of comparisons between studies, no increase in local recurrence or decrease in overall survival compared with rates with adjuvant whole-brain radiation therapy was found.

Trends in the outcomes for patients with limited stage small cell lung cancer : An analysis of the Surveillance, Epidemiology, and End Results database

We used the Surveillance, Epidemiology, and End Results (SEER) database to examine the outcomes of patients with limited stage small cell lung cancer (LS-SCLC) over time and to determine if any trends were present with respect to the publication of significant clinical trials. We assembled a cohort of 6271 patients aged 21 years and older with LS-SCLC diagnosed from 1983 to 1998 and followed through 2005. Potential covariates included patient age at diagnosis, sex, race, year of diagnosis, laterality, tumor size, and location (upper lobe, middle lobe, lower lobe, or main bronchus). In multivariate analysis, older age, male sex, African American race, and main bronchus location were all associated with a statistically significant increase in the mortality hazard. When compared to patients diagnosed in 1983-1987 who did not receive radiotherapy, the hazard for mortality was significantly reduced for patients diagnosed in 1988-1992 regardless of whether they received radiotherapy (HR=0.59; CI 0.52-0.65; p<0.0001) or not (HR=0.67; CI 0.60-0.75; p<0.0001). Patients who were diagnosed in 1993-1998 and received radiotherapy had similarly improved survival (HR=0.53; CI 0.47-0.58; p<0.0001), which was better than patients from the same time era who did not receive radiotherapy (HR=0.77; CI 0.69-0.85; p<0.0001). In conclusion, the survival for patients with LS-SCLC has improved over time. Many factors are likely involved, however we believe that part of this improvement was the result of clinical trials which investigated and subsequently defined chemoradiotherapy as the standard of care. In order to continue to improve clinical outcomes, clinical trials investigating new treatment paradigms are needed.

The influence of Hispanic ethnicity on nonsmall cell lung cancer histology and patient survival: An analysis of the Survival, Epidemiology, and End Results database

Most studies exploring ethnic/racial disparities in nonsmall cell lung cancer (NSCLC) compare black patients with whites. Currently, the effect of Hispanic ethnicity on the overall survival of NSCLC is poorly understood. Therefore, the authors carried out a large‐scale, population‐based analysis using the Surveillance, Epidemiology, and End Results (SEER) data base to determine the impact of Hispanic ethnicity the survival of patients with NSCLC.

ACR Appropriateness Criteria Nonsurgical Treatment for Non–Small-Cell Lung Cancer: Poor Performance Status or Palliative Intent

Radiation therapy plays a potential curative role in the treatment of patients with non-small-cell lung cancer with locoregional disease who are not surgical candidates and a palliative role for patients with metastatic disease. Stereotactic body radiation therapy is a relatively new technique in patients with early-stage non-small-cell lung cancer. A trial from RTOG(®) reported >97% local control at 3 years. For patients with locally advanced disease, thoracic radiation to a dose of 60 Gy remains the standard of care. Sequential chemotherapy or radiation alone can be used for patients with poor performance status who cannot tolerate more aggressive approaches. Chemotherapy should be used for patients with metastatic disease. Radiation therapy is useful for palliation of symptomatic tumors, and a dose of approximately 30 Gy is commonly used. Endobronchial brachytherapy is useful for patients with symptomatic endobronchial tumors. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every 2 years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances in which evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment.

ACR appropriateness criteria® radiation therapy for small-cell lung cancer

The current standard of care for small cell lung cancer is combined-modality therapy, including the use of chemotherapy, surgery (in selected cases of limited stage of disease), and radiation therapy. This review will focus on the role, dose fractionation, technology and timing of thoracic radiation, and the role and dose regimen of prophylactic cranial irradiation for both limited and extensive stage of diseases. Consensus recommendation from experts is summarized in the tables for 2 typical case scenarios.

ACR Appropriateness Criteria® Nonsurgical Treatment for Non-Small-Cell Lung Cancer: Good Performance Status/Definitive Intent

The optimal strategy for the non-surgical definitive treatment of patients with good performance status non-small cell lung cancer (mostly with locally advanced disease) has dramatically evolved over time. This article presents evidence-based data to review this literature. Several decades ago, the standard treatment for most stage III inoperable NSCLC was definitive radiation therapy alone. Randomized trials have since shown superior results with sequential chemotherapy and radiation, and more recently with concurrent chemoradiation, the current standard of care. Studies suggest a limited role for induction or adjuvant systemic therapy in addition to concurrent chemoradiation. The role of altered radiation fractionation techniques, such as hyperfractionation for locally advanced disease or hypofractionation for early stage disease is also discussed. More recently, the application of more advanced radiation techniques has been explored, including intensity modulated radiation therapy (IMRT) and proton beam radiation. Finally, various case variants are presented as examples of state-of-the-art treatment approaches.
