Abstract
BACKGROUND: Performance status (PS) is a commonly used factor in determining the appropriateness for chemotherapy of patients with non-small cell lung cancer (NSCLC). The prevalence of poor PS and impact of chemotherapy on survival among NSCLC patients has not been studied in community populations. PATIENTS AND METHODS: Insured patients, aged 50+ years, diagnosed with advanced stage NSCLC between 2000 and 2007 were identified via tumor registry (n=292) and linked to electronic medical records, automated medical claims, and Census tract information. A multivariate Cox proportional hazards model was used to determine the factors associated with survival. RESULTS: Of 292 stage IIIB-IV patients, 82 (28%) had PS 3 or 4, and 39% of PS 3-4 patients received first line chemotherapy. Those who received chemotherapy lived 4.8 months compared to 2.4 months for those who did not. Factors associated with a reduced likelihood of death included receipt of chemotherapy (hazard ratio [HR], 0.64), and female gender (HR, 0.71). Modern chemotherapy may be associated with positive effects on survival for poor PS patients, as for good PS patients. Further trials, especially randomized trials, in this neglected subgroup are indicated.

Surgical intervention for small-cell lung cancer: what is the surgical role?

Abstract
Small-cell lung cancer (SCLC) is an aggressive neuroendocrine carcinoma that accounts for approximately 10-15 % of all lung cancer cases. This histological subtype is a distinct entity with biological and oncological features differing from non-small cell lung cancer (NSCLC). Treatment is mainly performed using systemic chemotherapy, although surgery in association with chemotherapy may be indicated for a minor proportion of limited-disease cases. Since the outcomes after surgical intervention in patients with very early disease are comparable to those for NSCLC, accurate clinical staging is required, particularly in terms of nodal involvement. In addition to conventional mediastinoscopy, positron emission tomography-computed tomography and endobronchial ultrasonography guided transbronchial needle aspiration have recently become available for node diagnosis. The significance of surgery for SCLC includes local disease control and treatment for cases showing mixed histology. However, only two randomized control studies have examined the efficacy of surgery in SCLC, and both yielded negative results and are out of date. We review herein several studies concerning surgery for SCLC and discuss the results from a practical standpoint. A prospective trial performed in collaboration with pulmonologists is required to address the significance of surgery, which is a limited option in the treatment of SCLC.

Abstract
PURPOSE: The aims of this study were to investigate the impact of individual health-related quality of life (HRQL) evaluation on the attention towards symptom control and psychosocial function in advanced cancer patients. METHODS: Patients with advanced lung cancer or mesothelioma who attended a pulmonary oncology outpatient clinic were randomized to either of two strategies for HRQL assessment. The experimental group (EG) answered the EORTC QLQ-C30 + LC13 questionnaire using a digital table interface, with outprint of aggregated scale scores presented to the consulting physician as a support for evaluation. The control group (CG) answered a paper version of the same questionnaire, which was stored for later analysis. Consultations were audio-recorded. Outcome measures were a quantitative content analysis of audio-recorded consultations and medical and psychosocial interventions abstracted from clinical records. RESULTS: One hundred seventy-one patients were randomized and participated in the study. Issues regarding emotional function were more frequently discussed during consultations in the EG (p < 0.05). Similarly, interventions directed to emotional and social concerns were more frequent in the EG (p = 0.013 and p = 0.0036, respectively). HRQL measures over time were similar across the groups. CONCLUSION: Individual HRQL assessment increased the attention to psychosocial functioning in patients with chest malignancies.

Abstract
BACKGROUND: We investigated the association between the newly proposed International Association for the Study of Lung Cancer (IASLC)/American Thoracic Society (ATS)/European Respiratory Society (ERS) classification and (18)F-fluorodeoxyglucose (FDG) uptake on positron emission tomography (PET), and whether the combination of these radiologic and pathologic factors can further prognostically stratify patients with stage I lung adenocarcinoma. METHODS: We retrospectively evaluated 222 patients with pathologic stage I lung adenocarcinoma who underwent FDG-PET scanning before undergoing surgical resection between 1999 and 2005. Patients were classified by histologic grade according to the IASLC/ATS/ERS classification (low, intermediate, or high grade) and by maximum standard uptake value (SUVmax) (low <3.0, high ≥3.0). The cumulative incidence of recurrence (CIR) was used to estimate recurrence probabilities. RESULTS: Patients with high-grade histology had higher risk of recurrence (5-year CIR, 29 % [n = 25]) than those with intermediate-grade (13 % [n = 181]) or low-grade (11 % [n = 16]) histology (p = 0.046). High SUVmax was associated with high-grade histology (p < 0.001) and with increased risk of recurrence compared to low SUVmax (5-year CIR, 21 % [n = 113] vs. 8 % [n = 109]; p = 0.013). Among patients with intermediate-grade histology, those with high SUVmax had higher risk of recurrence than those with low SUVmax (5-year CIR, 19 % [n = 87] vs. 7 % [n = 94]; p = 0.033). SUVmax was associated with recurrence even after adjusting for pathologic stage (p = 0.037). CONCLUSIONS: SUVmax on FDG-PET correlates with the IASLC/ATS/ERS classification and can be used to stratify patients with intermediate-grade histology, the predominant histologic subtype, into two prognostic subsets.
