Abstract
INTRODUCTION This prospective observational study examined the adherence to published European guidelines on erythropoiesis-stimulating agents (ESAs) and the pattern of use and effect of darbepoetin alfa (DA) 500 microg once every 3 weeks (Q3W) for the treatment of chemotherapy-induced anaemia (CIA). MATERIALS AND METHODS A total of 293 patients were included (263 solid tumour, 30 haematologic malignancy). Their mean age was 63 years, 51% were male, 57% had platinum-based chemotherapy. DA was started at a haemoglobin (Hb) level between 9 and 11 g/dL in 82% of patients. RESULTS AND DISCUSSION In an analysis correcting for transfusions, 55% of patients achieved > or =2 g/dL increase in Hb, and a Hb level of >11 g/dL was reached in 81%. Transfusion rate was 27%. Most patients (70%) were treated in a Q3W chemotherapy, and planned synchronisation of chemotherapy and Q3W DA could be maintained in 76%. CONCLUSION Adherence to European guidelines for DA treatment was good, and Q3W DA treatment was in synchronisation with Q3W chemotherapy in the majority of the patients, thereby reproducing the findings of a recent phase III study.

Abstract
OBJECTIVE Due to recent advances in imaging, the incidence of patients presenting with bilateral lung lesions is increasing. A single contralateral lung lesion can be an isolated metastasis or a synchronous second primary lung cancer. For the revision of the TNM in 2009, the International Association for the Study of Lung Cancer Staging Committee proposes that patients with contralateral lung nodules remain classified as M1 disease. In this retrospective study, the survival after resection of synchronous bilateral lung cancer is evaluated. METHODS From our database of bronchial carcinoma, all patients with bilateral synchronous lung lesions between 1990 and 2007 were retrieved. We analysed 57 patients in which, after functional assessment and thorough staging, the decision was taken to treat the disease with bilateral resection. All these files were retrospectively reviewed. Twenty-one patients were excluded from this analysis because only one side was resected (n=15) or one of the lesions was non-neoplastic on final pathology (n=6). RESULTS Thirty-six patients underwent bilateral resection for synchronous multiple primary lung cancer. All resections were performed as sequential procedures. In 23 patients, one side was anatomically resected (2 pneumonectomies) and the contralateral side was resected by limited resection. In 10 patients a bilateral lobectomy was performed, and 3 patients had bilateral limited resections. Postoperative mortality was 2.8%. Eighteen patients had a tumour with a different histological pattern, confirmed by comparing both specimens by an experienced senior pathologist. The median survival after resection of synchronous bilateral lung cancer in our series was 25.4 months with a 5-year survival rate of 38%. There was no significant difference in survival between patients with different versus same histology. This survival is much higher compared to the survival of assumed stage IV disease. CONCLUSIONS Our study shows that selected patients with bilateral lung cancer may benefit from an aggressive approach, with acceptable morbidity and mortality, and rewarding long-term survival. Patients with a single contralateral lung lesion should not be treated as disseminated disease (stage IV). After extensive searching for metastatic spread, bilateral surgical resection should be considered in fit patients.

Abstract
PurposeCisplatin plus gemcitabine is a standard regimen for first-line treatment of advanced non–small-cell lung cancer (NSCLC). Phase II studies of pemetrexed plus platinum compounds have also shown activity in this setting.Patients and MethodsThis noninferiority, phase III, randomized study compared the overall survival between treatment arms using a fixed margin method (hazard ratio [HR] < 1.176) in 1,725 chemotherapy-naive patients with stage IIIB or IV NSCLC and an Eastern Cooperative Oncology Group performance status of 0 to 1. Patients received cisplatin 75 mg/m2on day 1 and gemcitabine 1,250 mg/m2on days 1 and 8 (n = 863) or cisplatin 75 mg/m2and pemetrexed 500 mg/m2on day 1 (n = 862) every 3 weeks for up to six cycles.ResultsOverall survival for cisplatin/pemetrexed was noninferior to cisplatin/gemcitabine (median survival, 10.3 v 10.3 months, respectively; HR = 0.94; 95% CI, 0.84 to 1.05). Overall survival was statistically superior for cisplatin/pemetrexed versus cisplatin/gemcitabine in patients with adenocarcinoma (n = 847; 12.6 v 10.9 months, respectively) and large-cell carcinoma histology (n = 153; 10.4 v 6.7 months, respectively). In contrast, in patients with squamous cell histology, there was a significant improvement in survival with cisplatin/gemcitabine versus cisplatin/pemetrexed (n = 473; 10.8 v 9.4 months, respectively). For cisplatin/pemetrexed, rates of grade 3 or 4 neutropenia, anemia, and thrombocytopenia (P ≤ .001); febrile neutropenia (P = .002); and alopecia (P < .001) were significantly lower, whereas grade 3 or 4 nausea (P = .004) was more common.ConclusionIn advanced NSCLC, cisplatin/pemetrexed provides similar efficacy with better tolerability and more convenient administration than cisplatin/gemcitabine. This is the first prospective phase III study in NSCLC to show survival differences based on histologic type.

Abstract
Vorinostat (Zolinza) is a histone deacetylase inhibitor that has demonstrated activity in patients with advanced solid tumors in phase I trials. A multicenter, open-label phase II trial of oral vorinostat 200, 300 or 400 mg bid for 14 days followed by a 7-day rest until disease progression or intolerable toxicity was conducted. Patients with measurable, relapsed or refractory breast or non-small cell lung cancer who had received > or = 1 prior therapy or colorectal cancer who had received > or = 2 prior therapies were eligible. The response rate, safety and tolerability were evaluated. Sixteen patients (median age, 62 years; median 5.5 prior therapies) were enrolled. Six patients received 400 mg bid, six received 300 mg bid and four received 200 mg bid (14 days/3 weeks). Dose-limiting toxicities (DLTs) at the 400 or 300 mg bid levels were anorexia, asthenia, nausea, thrombocytopenia, vomiting, and weight loss. No DLTs were observed at the 200 mg bid level. Disease stabilization was observed in eight patients, but there were no confirmed responses. The median TTP was 33.5 days. Eleven patients discontinued due to clinical adverse experiences (AEs). The most common drug-related AEs were anorexia (81%), fatigue (62%), nausea (62%), diarrhea (56%), vomiting (56%), thrombocytopenia (50%) and weight loss (50%). Drug-related AEs > or = grade 3 included thrombocytopenia (50%), anemia (12%), asthenia (12%) and nausea (12%). Vorinostat in a daily oral schedule for 14 days/3 weeks was tolerable at 200 mg bid only, and no responses were observed in this study. Most patients, however, had limited drug exposure which did not allow a reliable efficacy analysis.

Abstract
BACKGROUND The effect of chemotherapy on survival of patients with advanced NSCLC is modest, therefore patient reported outcomes (PRO's) are of high interest in randomized controlled trials (RCTs). CONSORT (CONsolidated Standards On Reporting Trials) is a quality checklist of 22 items for the conduct and reporting of RCTs. The aim of this report was to analyse to what extent the different RCTs with information on PRO's adhere to the CONSORT statement. METHODS Systematic review of RCTs using PRO's either as primary or secondary endpoint. Compliance with the (revised) CONSORT statement was checked by 2 independent reviewers by making for each study the simple sum of the 22 CONSORT items, or a weighted score with a maximum rating of 31 points. RESULTS The median weighted CONSORT score of the different RCTs was 25, with a remarkable difference from 12 till 30. There was no significant change over time, nor difference between academic and commercial studies, but a significant correlation between CONSORT agreement and journal type (P<0.0001). Adherence to CONSORT was similar for studies comparing chemotherapy with best supportive care alone, comparing different first-line chemotherapies with PRO either as primary or secondary endpoint, or studies looking at second-line chemotherapy. Benefit in PRO's was reported in all of these settings. CONCLUSION The overall adherence of peer-reviewed RCTs to CONSORT is reasonable, with nonetheless major differences between journals, and with no clear sign of change over time. Apart from modest survival differences, benefits in PRO endpoints are present in all categories of studies we analysed.

Abstract
PURPOSE Surgical resection in patients with stage IIIA-N2 non-small-cell lung cancer (NSCLC) is usually reserved for patients with mediastinal downstaging after induction chemotherapy (IC). However, clinical restaging is often inaccurate, and there are insufficient data to conclude that all patients with persistent mediastinal disease will not benefit from surgery, or that all patients with mediastinal clearance benefit from surgery. We created a data-based restaging strategy combining morphometric tissue analysis of mediastinal lymph nodes (LNs) and 18-fluoro-2-deoxy-glucose positron emission tomography (FDG-PET) response monitoring in the primary tumor. PATIENTS AND METHODS Baseline and repeat FDG-PET after IC, as well as complete resection specimens of both mediastinal LNs and primary tumor, were available in 30 patients. Histologic response grading was performed by means of conventional morphometric procedures. Mediastinal response grading combined with the percentage decrease of maximum standardized uptake value (SUV(max)) on the primary tumor was correlated with survival. RESULTS Patients with persistent major mediastinal LN involvement have a 5-year overall survival rate of 0%. The 5-year overall survival rate for patients with cleared or persistent minor mediastinal LN involvement was significantly higher in patients with a more than 60% decrease in SUV(max) on the primary tumor as compared with patients with a less than 60% decrease in SUV(max) (62% v 13%; log-rank P = .002). CONCLUSION These data may suggest that (1) persistent mediastinal disease after IC does not always exclude favorable outcome after surgery; (2) serial FDG-PET may select surgical candidates among patients with mediastinal downstaging or persistent minor disease; (3) persistent major mediastinal disease has a poor prognosis and such patients should not be considered for surgery.

Abstract
Anemia is a frequent problem in cancer patients, especially in those treated with chemotherapy, and has an important negative impact on quality of life. Red blood cell transfusions provide clear but rather temporary comfort. The development of erythropoietic stimulating agents (ESAs) led to a more durable anemia treatment. Darbepoetin alpha is a unique ESA with a long plasma half life, thereby suitable for administration with different dosing intervals. Apart from administration every week, darbepoetin alpha also proved to be efficient in reducing red blood cell transfusion rates and in improving health-related quality of life when administered at a dose of 500 microg once every 3 weeks. This is a convenient therapy schedule because it can be synchronized with the chemotherapy cycle in many patients. Recently, concerns have been raised about the long-term safety of ESAs, more specifically about their effect on survival. Available data must be interpreted with caution, but at present there is no clear evidence to support a negative effect on outcome with darbepoetin alpha therapy when used according to the guidelines for treatment of chemotherapy-induced anemia. Further studies focusing on survival as the primary end point are ongoing.

Abstract
BACKGROUND The treatment of non-small cell lung cancer (NSCLC) is determined by accurate definition of the stage. If there are no distant metastases, the status of the mediastinal lymph nodes is critical. Although imaging studies can provide some guidance, in many situations invasive staging is necessary. Many different complementary techniques are available. METHODS The current guidelines and medical literature that are applicable to this issue were identified by computerized search and were evaluated using standardized methods. Recommendations were framed using the approach described by the Health and Science Policy Committee of the American College of Chest Physicians. RESULTS Performance characteristics of invasive staging interventions are defined. However, a direct comparison of these results is not warranted because the patients selected for these procedures have been different. It is crucial to define patient groups, and to define the need for an invasive test and selection of the best test based on this. CONCLUSIONS In patients with extensive mediastinal infiltration, invasive staging is not needed. In patients with discrete node enlargement, staging by CT or positron emission tomography (PET) scanning is not sufficiently accurate. The sensitivity of various techniques is similar in this setting, although the false-negative (FN) rate of needle techniques is higher than that for mediastinoscopy. In patients with a stage II or a central tumor, invasive staging of the mediastinal nodes is necessary. Mediastinoscopy is generally preferable because of the higher FN rates of needle techniques in the setting of normal-sized lymph nodes. Patients with a peripheral clinical stage I NSCLC do not usually need invasive confirmation of mediastinal nodes unless a PET scan finding is positive in the nodes. The staging of patients with left upper lobe tumors should include an assessment of the aortopulmonary window lymph nodes.

Abstract
PurposeIxabepilone is the first in a new class of antineoplastic agents, the epothilones and their analogs. This international, randomized, phase II trial assessed two administration schedules of ixabepilone as second-line therapy in patients with non–small-cell lung cancer (NSCLC).Patients and MethodsPatients had experienced disease progression after one prior cisplatin- or carboplatin-based chemotherapy regimen. Ixabepilone was administered as a single 32 mg/m23-hour infusion (77 patients; arm A) or a 6 mg/m21-hour infusion daily for 5 consecutive days (69 patients; arm B) in a 3-week cycle.ResultsThe intent-to-treat objective response rate was 14.3% in arm A and 11.6% in arm B. Median duration of response was 8.7 months (95% CI, 5.3 to 9.5 months) in arm A and 9.6 months (95% CI, 6.1 to 19.7 months) in arm B. Median time to progression was 2.1 months (95% CI, 1.4 to 2.8 months) for arm A and 1.5 months (95% CI, 1.4 to 2.8 months) for arm B. Median survival was 8.3 months (95% CI, 5.8 to 11.5 months) for arm A, and 7.3 months (95% CI, 5.7 to 11.7 months) for arm B; the 1-year survival rate (both cohorts) was 38%. Responses occurred in patients with taxane-pretreated and platinum-refractory tumors. Both regimens had an acceptable toxicity profile. Myelosuppression was manageable, manifesting primarily as neutropenia and leukopenia. Neuropathy was primarily sensory, generally mild to moderate in severity, and mostly reversible (both regimens).ConclusionSingle-agent ixabepilone had clinically relevant activity and an acceptable safety profile in patients with advanced NSCLC whose tumors had failed one prior platinum-based chemotherapy regimen.

Abstract
The management of advanced non-small cell lung cancer (NSCLC) has progressed over the last 3 decades. Advances in chemotherapeutic drugs and the use of multi-drug combinations, targeted agents and new management strategies have provided modest survival benefits. However, improving quality of life is equally important, and involves a therapeutic strategy that considers the optimal balance between treatment activity (survival; symptom control) and treatment burden (side effects; duration of hospital stay). There remains room for improvement of therapies today, given that 1-year survival is approximately 35%. The option of adding another cytotoxic agent to a platinum-based doublet does not appear to improve survival but increases toxicity. With the advent of targeted drugs, there is much interest in adding a biological agent such as bevacizumab to the current standard. Another strategy of interest is the use of maintenance treatment with a well-tolerated cytotoxic agent such as gemcitabine after first-line therapy. This has been shown to improve progression-free survival compared with best supportive care alone. Ten years ago, few patients with advanced NSCLC were candidates for second-line treatment for progressive or relapsed disease. However, as response rates and toxicity profiles with first-line therapies improved, relapse therapy has become more important. Several single agent chemotherapies have been evaluated in the second-line setting, including the anti-metabolite pemetrexed, which demonstrates comparable survival outcomes to that of the historical standard docetaxel, but a much better toxicity profile. The targeted therapy erlotinib is also being investigated in this setting. Further studies are required to establish the role of newer agents in the management of advanced NSCLC.

Abstract
PURPOSE OF REVIEW [(8)F]2-Fluoro-2-deoxy-glucose positron emission tomography is an important functional imaging technique for the diagnosis, staging and follow-up of patients with nonsmall cell lung cancer. We review recent developments with the emphasis on impact of positron emission tomography in early diagnosis, staging, restaging and prognosis of nonsmall cell lung cancer. RECENT FINDINGS Data on the use and interpretation of positron emission tomography became available for small pulmonary nodules. We should abandon the 'magic' standardized uptake value threshold of 2.5 and rather make a visual assessment in this setting. The high negative predictive value of positron emission tomography in mediastinal staging was confirmed in a large prospective study. Tissue confirmation of all qualitative or quantitative suspicious mediastinal lymph nodes at positron emission tomography remains required. Minimally invasive techniques such as endobronchial ultrasound-guided transbronchial needle aspiration seem promising in this setting with sensitivities up to 90%. Recent data also point at integrated positron emission tomography/computed tomography as a tool for response assessment of mediastinal nodes and, more interestingly, of the primary tumor. Positron emission tomography has the potential to predict survival based on baseline positron emission tomography stage and standardized uptake value, visual [(18)F]2-fluoro-2-deoxy-glucose uptake at the time of suspected recurrence, and change in [(18)F]2-fluoro-2-deoxy-glucose uptake after neoadjuvant therapy. SUMMARY Refinements in diagnosis and staging, as well as newer applications such as guidance of endoscopy and assessment of treatment, are described.

Abstract
Imaging techniques play a vital role in the diagnosis, staging, and follow-up of patients who have lung cancer. For this purpose, PET has become an important adjunct to conventional imaging techniques such as chest radiography, CT, ultrasonography, and MR imaging. The ability of PET to differentiate the metabolic properties of tissues allows more accurate assessment of undetermined lung lesions, mediastinal lymph nodes, or extrathoracic abnormalities, tumor response after induction treatment, and detection of disease recurrence.

Abstract
INTRODUCTION Accurate staging of lymph node involvement is a critical aspect of the initial management of nonmetastatic non-small cell lung cancer (NSCLC). We sought to determine whether the current N descriptors should be maintained or revised for the next edition of the international lung cancer staging system. METHODS A retrospective international lung cancer database was developed and analyzed. Anatomical location of lymph node involvement was defined by the Naruke (for Japanese data) and American Thoracic Society (for non-Japanese data) nodal maps. Survival was calculated by the Kaplan-Meier method, and prognostic groups were assessed by Cox regression analysis. RESULTS Current N0 to N3 descriptors defined distinct prognostic groups for both clinical and pathologic staging. Exploratory analyses indicated that lymph node stations could be grouped together into six "zones": peripheral or hilar for N1, and upper or lower mediastinal, aortopulmonary, and subcarinal for N2 nodes. Among patients undergoing resection without induction therapy, there were three distinct prognostic groups: single-zone N1, multiple-zone N1 or single N2, and multiple-zone N2 disease. Nevertheless, there were insufficient data to determine whether the N descriptors should be subdivided (e.g., N1a, N1b, N2a, N2b). CONCLUSIONS Current N descriptors should be maintained in the NSCLC staging system. Prospective studies are needed to validate amalgamating lymph node stations into zones and subdividing N descriptors.

Abstract
7654 Background: Vandetanib (ZD6474) is a once-daily oral anticancer drug that selectively inhibits VEGF-dependent tumor angiogenesis and EGFR- and RET-dependent tumor cell proliferation and survival. Methods: Eligible patients had locally advanced or metastatic NSCLC (stage IIIB/IV) after failure of 1st-line chemotherapy. An initial cohort of 10 patients received once- daily oral vandetanib (100 mg) with pemetrexed (500 mg/m2 i.v. infusion every 21 days). If <2 patients experienced a vandetanib- related dose-limiting toxicity (DLT), an additional cohort received vandetanib 300 mg + pemetrexed. The planned duration of treatment was =6 weeks. The primary objective of the study was to establish the safety and tolerability of vandetanib + pemetrexed. Secondary objectives included an assessment of pharmacokinetic (PK) interaction and preliminary assessment of efficacy (RECIST). Results: Twenty- one patients (14 male, 7 female; mean age 60 years, range 44–77) received vandetanib 100 mg + pemetrexed (n=10) or vandetanib 300 mg + pemetrexed (n=11). One DLT was reported in each cohort: QTc prolongation (>100 ms from baseline, but absolute QTc <500 ms) in a male patient who had electrolyte imbalance and short baseline QTc interval of 318 ms (100 mg cohort); and interstitial lung disease, which resolved after steroid therapy, in a Caucasian female patient with bronchoalveolar carcinoma and a long smoking history (300 mg cohort). The most common adverse events (AEs) were rash, anorexia, fatigue and diarrhea (all n=10; 48%). The most frequent CTC grade 3/4 AEs were increased gamma-glutamyltransferase (n=4), anorexia (n=3) and dyspnea (n=3), which are generally consistent with previous experience with vandetanib and pemetrexed as monotherapies. There was no apparent PK interaction between vandetanib and pemetrexed. In 18 patients evaluable for efficacy, there was one confirmed partial response (female; 100 mg cohort) and 13 stable disease =6 weeks. Conclusions: In patients with advanced NSCLC, vandetanib + pemetrexed was generally well tolerated, with no apparent PK interaction. A Phase III trial of vandetanib 100 mg + pemetrexed in 2nd-line NSCLC has begun. No significant financial relationships to disclose.

Abstract
9106 Background: Pts with CIA receiving erythropoiesis-stimulating agents (ESAs) may benefit from IV iron supplementation. This randomized, multicenter, open-label, 16-week, phase IIIb study evaluated the safety and efficacy of darbepoetin alfa in pts with CIA who also received IV iron versus oral iron/no iron. This exploratory analysis presents the clinical outcomes by subgroups based on baseline (BL) hemoglobin (Hb). Methods: Eligible pts were of legal age, had a non-myeloid malignancy, and had CIA (BL Hb < 11g/dL). All pts received DA 500 mcg administered Q3W using the Aranesp (darbepoetin alfa) prefilled SureClick autoinjector. Patients were randomly allocated 1:1 to receive either DA plus 200 mg IV iron (200 mg Q3W with DA Q3W or two 100 mg doses within 3 weeks) or DA plus oral iron/no iron. Randomization was stratified by tumor type and BL Hb category (< 10 or = 10 g/dL). The primary endpoint was the percentage of pts achieving a hematopoietic response (Hb = 12 g/dL or an increase = 2 g/dL). Results: A total of 396 pts were randomized and received = 1 dose of DA (IV iron arm = 200; oral iron/no iron arm = 196). Mean (SD) age was 61.0 (11.5) years; 61% (n = 240) were women; 28% (n = 111) had lung or gynecological tumors; and 45% (n = 178) had BL Hb < 10 g/dL. Pt demographics were similar between arms. Clinical outcomes are shown in the table by BL Hb. Conclusions: DA 500 mcg Q3W with IV iron supplementation appeared to improve clinical outcomes in this study, especially in pts with BL Hb < 10 g/dL; more pts achieved a hematopoietic response, fewer received transfusions, and more achieved the target Hb (= 11 g/dL) compared with those receiving oral iron/no iron. Also, in both treatment arms, pts with BL Hb = 10 g/dL demonstrated better clinical outcomes than pts with BL Hb < 10 g/dL. Benefits associated with initiating ESA treatment on time, ie before pts Hb falls < 10 g/dL, have been suggested previously (Lyman and Glaspy, Cancer 2006).

Abstract
7554 Background: After complete resection, about 50% of patients with stages IB-II NSCLC disease die within 5 years. Adjuvant chemotherapy improves overall survival at the expense of substantial toxicity. Activity of MAGE-A3 immunotherapeutic (i.e. recombinant MAGE-A3 protein and a potent GlaxoSmithKline adjuvant) was previously demonstrated in metastatic melanoma. As about 35% of NSCLCs express MAGE-A3 antigen, post-operative MAGE-treatment may be a tumor-specific, well tolerated, and effective adjuvant therapy. Methods: Patients with completely resected, MAGE-A3 (+), stage pIB or pII were randomly assigned to postoperative MAGE-A3 or placebo (2:1), with 5 administration at 3-week intervals, followed by 8 administrations every 3 months. Randomization was stratified for stage (IB vs. II), histology (squamous vs. other), and lymph-node (LN) procedure (sampling vs. dissection). Primary endpoint was disease-free interval (DFI); other endpoints were safety, disease-free survival (DFS), and overall survival (OS). This exploratory Phase II study was designed to detect a clinically relevant HR with a 10% one-sided a. Results: 182 patients (122 stage IB, 60 stage II) from 59 centers in 14 countries were randomized over 2 years: Median age 63 (45–81); 87% male; 65% squamous cell carcinoma; 65% lymph-node dissection. After a median follow-up of 28 months, 67 recurrences and 45 deaths were recorded. Group comparisons of DFI, DFS and OS gave respectively a hazard ratio (HR) of 0.74 (95% CI 0.44–1.20, p=0.107), 0.73 (95% CI 0.45–1.16) and 0.66 (95% CI 0.36–1.20) in favor of the MAGE-A3 group. Overall, treatment was well tolerated, with excellent protocol compliance. Subset analysis also suggests that LN dissection may have an effect on survival. Conclusions: The final analysis of this randomized phase II study shows a positive trend for activity of MAGE-A3 treatement in NSCLC with a relative improvement of DFI and DFS of 27%. Further phase III evaluation is planned. This study also suggests that complete lymph-node dissection may have an effect on survival and should be confirmed prospectively. [Table: see text]

Abstract
The purpose of this study was to investigate the relation between the standardised uptake value (SUV) on (18)F-fluoro-2-deoxy-glucose-positron emission tomography scan and hypoxia related markers (HIF-1alpha and CAIX), a proliferation-related marker (Ki-67) and glucose transporters (GLUT-1 and GLUT-3) in non-small cell lung cancer (NSCLC). One hundred and two patients, scheduled for complete resection, received a PET scan in Leuven or Maastricht/Aachen. The maximal SUV (SUV(max)) was correlated with survival and immunohistochemical staining patterns. The actuarial survival was worse for patients showing a high SUV(max), the best discriminative value being 8.0 (Leuven, p=0.032) and 11.0 (Maastricht, p=0.007). Tumours with a high SUV(max) expressed in a higher proportion HIF-1alpha (63.1% versus 37.9%, p=0.024) and GLUT-1 (82.9% versus 62.5%, p=0.025), than tumours with a low SUV(max). No significant difference was found in the expression of CAIX, Ki-67 and GLUT-3. This study supports preclinical data that hypoxia is associated with a higher uptake of FDG.

Abstract
BACKGROUND We undertook a systematic review and literature-based meta-analysis to determine whether the timing of chest radiotherapy may influence the survival of patients with limited stage small cell lung cancer (LS-SCLC). OBJECTIVES To establish the most effective way of combining chest radiotherapy with chemotherapy for patients with limited-stage small cell lung cancer in order to improve long-term survival. MATERIALS Eligible studies were identified according to the Cochrane Collaboration Guidelines and were randomised controlled clinical trials comparing different timing of chest radiotherapy in patients with LS-SCLC. Early chest irradiation was defined as beginning within 30 days after the start of chemotherapy. RESULTS Seven randomised trials were eligible. The overall survival at 2 years or at 5 years was not significantly different between early or late chest radiotherapy. When only trials were considered that used platinum chemotherapy concurrent with chest radiotherapy, significantly higher 2 and 5-year survival rates were observed when chest radiotherapy (RT) was started within 30 days after the start of chemotherapy (2-year survival: HR: 0.73, 95% CI 0.57-0.94, p=0.01; 5-year survival: HR: 0.65, 95% CI 0.45-0.93, p=0.02). This was even more pronounced when the overall treatment time of chest radiotherapy was less than 30 days. In studies that did not show a survival advantage by early chest radiation, a lower dose-intensity of chemotherapy in the early vs. late arm was observed. CONCLUSIONS When platinum-based chemotherapy concurrently with chest RT is used, the 2- and 5-year survival rates of patients with LS-SCLC may be in favour of early chest radiotherapy, with a significant difference if the overall treatment time of chest radiation is less than 30 days.

Abstract
PURPOSE Erlotinib is a potent inhibitor of the epidermal growth factor receptor tyrosine kinase, with single-agent antitumor activity. Preclinically, erlotinib enhanced the cytotoxicity of chemotherapy. This phase III, randomized, double-blind, placebo-controlled, multicenter trial evaluated the efficacy and safety of erlotinib in combination with cisplatin and gemcitabine as first-line treatment for advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Patients received erlotinib (150 mg/d) or placebo, combined with up to six 21-day cycles of chemotherapy (gemcitabine 1,250 mg/m2 on days 1 and 8 and cisplatin 80 mg/m2 on day 1). The primary end point was overall survival (OS). Secondary end points included time to disease progression (TTP), response rate (RR), duration of response, and quality of life (QoL). RESULTS A total of 1,172 patients were enrolled. Baseline demographic and disease characteristics were well balanced. There were no differences in OS (hazard ratio, 1.06; median, 43 v 44.1 weeks for erlotinib and placebo groups, respectively), TTP, RR, or QoL between treatment arms. In a small group of patients who had never smoked, OS and progression-free survival were increased in the erlotinib group; no other subgroups were found more likely to benefit. Erlotinib with chemotherapy was generally well tolerated; incidence of adverse events was similar between arms, except for an increase in rash and diarrhea with erlotinib (generally mild). CONCLUSION Erlotinib with concurrent cisplatin and gemcitabine showed no survival benefit compared with chemotherapy alone in patients with chemotherapy-naïve advanced NSCLC.

Abstract
PURPOSE OF REVIEW Positron emission tomography (PET) has become a major adjunct to structural imaging for nonsmall cell lung cancer. Established indications are the differential diagnosis of lung nodules, as well as mediastinal lymph node and extrathoracic staging. RECENT FINDINGS More details for small or faint pulmonary nodules became available--information of interest in the era of lung cancer screening trials, in which PET might help to reduce unwanted invasive procedures for benign findings. The strength of PET in mediastinal staging (its high negative predictive value) was confirmed in a randomized study, in which PET reduced the number of invasive procedures without loss of accuracy in staging. Isolated positive lesions that are decisive for radical compared with palliative treatment should be confirmed by other tests, as they may be benign or due to second primary cancer. PET with integrated computed tomography (CT) may guide modern radiotherapy, by improving radiation fields. Integrated PET-CT is a promising tool in the indication for surgery in stage IIIA-N2 patients after induction treatment. Predictive values for lymph node downstaging become in acceptable ranges and PET response in the primary tumor could be clearly linked to pathologic response and survival. SUMMARY In recent years, PET has seen further refinements in established indications and definition of new indications.

Abstract
Gradual but positive progress is being made in the field of non-small-cell lung cancer (NSCLC) treatment, including the implementation of more effective strategies for the use of second-line therapy. Clinical consideration of the available options for previously treated patients is a relatively recent concept, the application of which looked doubtful even a decade ago due to the poor prognosis of NSCLC patients receiving first-line chemotherapy. However, the 21st century has witnessed improved rates of response, median survival and 1 year survival following second-line treatment of NCSLC, and the therapeutic armamentarium continues to grow in this setting. Therefore, current challenges include the identification of the most appropriate second-line regimen and determination of the best way to position this within a logical, evidence-based treatment sequence.

Abstract
Epidermal growth factor receptor tyrosine kinase inhibitors represent a new treatment option for patients with advanced nonsmall cell lung cancer (NSCLC). This retrospective study examined to what extent previous clinical trial experience matches large-scale Western community implementation of this treatment. In the Belgian expanded access programme, the data from 513 patients with advanced or metastatic NSCLC, not suitable for further chemotherapy and receiving oral gefitinib 250 mg.day(-1) until disease progression, death or unacceptable toxicity, were analysed. The median (range) duration of gefitinib treatment was 2.3 months (0.0-32.7). Its use was predominantly in second- or third-line treatment. The overall response and disease control rates were 8.9 and 41.2%, respectively. In univariate analysis, response was more common in females and never-smokers. In multivariate analysis, female sex was the only significant predictive factor (odds ratio (OR) (95% confidence interval (CI)) 0.329 (0.129-0.839)). Symptom improvement was reported in 108 patients of whom 32 (29.6%) had an objective response, 66 (61.1%) experienced disease stabilisation and 10 (9.3%) progressed. Gefitinib was well tolerated; only 7.8% of the patients reported grade 3 or 4 toxicity. The overall median survival was 4.7 months, with a 1-yr survival rate of 21%. Survival was strongly influenced by a better performance status (PS) (good PS: hazard ratio (HR) (95%CI) 0.110 (0.077-0.157)) and adenocarcinoma with bronchioloalveolar carcinoma features histology (HR (95%CI) 0.483 (0.279-0.834)). In conclusion, the activity of gefitinib was confirmed in the present large Western community implementation study. Response, present in a small subgroup, led to a rewarding survival and could be predicted by sex only. Baseline performance status and adenocarcinoma with bronchioloalveolar carcinoma features histology were significant factors for survival.

Abstract
PURPOSE Mediastinal restaging after induction therapy for non-small-cell lung cancer remains a difficult and controversial issue. The goal of this prospective study was to compare the performance of integrated positron emission tomography (PET)--computed tomography (CT) and remediastinoscopy in the evaluation of mediastinal lymph node metastasis after induction chemotherapy. PATIENTS AND METHODS Thirty consecutive stage IIIA-N2 non-small-cell lung cancer patients surgically treated at our institution were entered onto this prospective study. N2 disease was proven by cervical mediastinoscopy, at which a mean number of 3.8 lymph node levels were biopsied. After completion of induction chemotherapy, the mediastinum was reassessed by integrated PET-CT and remediastinoscopy. All patients underwent thoracotomy with attempted complete resection and systematic nodal dissection. RESULTS PET-CT showed no evidence of nodal disease (N0) in 13 patients, Hilar nodal disease (N1) disease in three patients, and residual mediastinal disease (N2) in 14 patients. Remediastinoscopy was positive in only five patients. The preinduction involved lymph node level could be accurately re-evaluated in 18 patients. This was not the case in the other 12 because of extensive fibrosis and adhesions. In 17 patients, persistent N2 disease was found at thoracotomy. The sensitivity, specificity, and accuracy of PET-CT were 77%, 92%, and 83%, respectively. These parameters for remediastinoscopy were 29%, 100%, and 60%, respectively. Sensitivity (P < .0001) and accuracy (P = .012) were significantly better for PET-CT. CONCLUSION After a thorough staging mediastinoscopy, postinduction remediastinoscopy had a disappointing sensitivity because of adhesions and fibrosis. Integrated PET-CT yielded a better result than that obtained in previous studies with side-by-side PET and CT images.

Abstract
7019 Background: About half of the patients with completely resected early-stage NSCLC will relapse. Adjuvant chemotherapy reduces the number of relapses at the expense of substantial toxicity. Activity of MAGE-A3 vaccination (i.e. recombinant MAGE-A3 protein and a potent GSK immunological adjuvant) has been proven in advanced melanoma. As about 35% of NSCLCs express the MAGE-A3 antigen, post-operative MAGE-A3 vaccination may be a targeted, well tolerated, and effective adjuvant therapy. Methods: Patients with completely resected, MAGE-A3 positive (assessed by quantitative RT-PCR), stage pIB or pII were 2:1, double-blind, randomly assigned to postoperative MAGE-A3 vaccination or placebo. Vaccination was started ≥6 weeks after surgery, with 5 vaccinations at 3-week intervals, followed by 8 vaccinations every 3 months. Randomization was stratified for stage (IB vs. II), histology (squamous vs. other), and lymph node procedure (sampling vs. dissection). Other anti-cancer adjuvant therapy was not allowed. Primary endpoint was time-to-recurrence, other endpoints were recurrence rates at different times, and survival. A sample size of 180 patients (120 active, 60 placebo) was chosen, to achieve 48% power (α=10%) to detect a 10% difference, assuming a 40% recurrence rate at month 30 in the placebo group (log rank test). A thorough interim efficacy analysis by an independent statistician (blinded to investigators and sponsor) is planned for 18 months after completion of recruitment. Results: 35% of 1,089 biopsies from 59 sites were MAGE-A3 positive. In two years, 182 patients were randomized (121 stage IB, 61 stage II). Overall, treatment was well tolerated, with high protocol compliance. Data collection for the interim efficacy analysis was initiated on December 19th, 2005. Median follow-up was 21 months, with 62 recurrences recorded. Conclusions: This study confirms expression of MAGE-A3 antigen in 35% of early NSCLC cases, and demonstrates good tolerability of postoperative MAGE-A3 vaccination. Efficacy results of the interim analysis will be available in February 2006. [Table: see text]

BACKGROUND We undertook a systematic review and literature-based meta-analysis to determine whether the timing of chest radiotherapy may influence the survival of patients with limited-stage small-cell lung cancer (LS-SCLC). MATERIALS Eligible randomised controlled clinical trials were identified according to the Cochrane Collaboration Guidelines, comparing different timing of chest radiotherapy in patients with LS-SCLC. Early chest irradiation was defined as beginning within 30 days after the start of chemotherapy. RESULTS Considering all seven eligible trials, the overall survival at 2 or 5 years was not significantly different between early or late chest radiotherapy. When only trials were considered that used platinum chemotherapy concurrent with chest radiotherapy, a significantly higher 5-year survival was observed when chest radiotherapy was started within 30 days after the start of chemotherapy (2-year survival: OR: 0.73, 95% CI 0.51-1.03, P = 0.07; 5-year survival: OR: 0.64, 95% CI 0.44-0.92, P = 0.02). This was even more pronounced when the overall treatment time of chest radiotherapy was less than 30 days. CONCLUSIONS There are indications that the 5-year survival rates of patients with LS-SCLC are in favour of early chest radiotherapy, with a significant difference if the overall treatment time of chest radiation is less than 30 days.

Abstract
PURPOSE To identify time factors for combined chemotherapy and radiotherapy predictive for long-term survival of patients with limited-disease small-cell lung cancer (LD-SCLC). METHODS A systematic overview identified suitable phase III trials. Using meta-analysis methodology to compare results within trials, the influence of the timing of chest radiation and the start of any treatment until the end of radiotherapy (SER) on local tumor control, survival, and esophagitis was analyzed. For comparison between studies, the equivalent radiation dose in 2-Gy fractions, corrected for the overall treatment time of chest radiotherapy, was analyzed. RESULTS The SER was the most important predictor of outcome. There was a significantly higher 5-year survival rate in the shorter SER arms (relative risk [RR] = 0.62; 95% CI, 0.49 to 0.80; P = .0003), which was more than 20% when the SER was less than 30 days (upper bound of 95% CI, 90 days). A low SER was associated with a higher incidence of severe esophagitis (RR = 0.55; 95% CI, 0.42 to 073; P < .0001). Each week of extension of the SER beyond that of the study arm with the shortest SER resulted in an overall absolute decrease in the 5-year survival rate of 1.83% +/- 0.18% (95% CI). CONCLUSION A low time between the first day of chemotherapy and the last day of chest radiotherapy is associated with improved survival in LD-SCLC patients. The novel parameter SER, which takes into account accelerated proliferation of tumor clonogens during both radiotherapy and chemotherapy, may facilitate a more rational design of combined-modality treatment in rapidly proliferating tumors.

Abstract
Chemotherapy-induced anaemia, with its important consequences on quality of life and social function of cancer patients, can be improved with erythropoietic therapy. Darbepoetin alfa is the first of a novel generation of erythropoietic proteins with a unique molecular structure and a circulating half-life that is threefold longer than that of the previous recombinant human erythropoietin. The efficacy and safety of weekly administration have been confirmed in different Phase II and III randomised trials. In order to optimise the efficacy profile of darbepoetin alfa, extended dosing intervals and front-loading regimens are evaluated, as well the optimal haemoglobin level to initiate therapy. Across all trials, darbepoetin alfa was shown to be a well-tolerated and safe therapy. The possible favourable effect on the outcome of cancer patients needs to be further elucidated.

Abstract
BACKGROUND In the United States, darbepoetin alfa (Aranesp) is often used to treat patients with chemotherapy-induced anemia using weekly or every-2-week administration schedules. In Europe, darbepoetin alfa is used either weekly or in every-3-week dosing. The every-3-week schedule can be synchronized with many chemotherapy regimens, resulting in fewer visits and reducing burden to patients, but the safety and efficacy of this regimen have not been clear. METHODS A randomized, double-blind, double-dummy, active-controlled phase 3 trial was performed in 110 European centers. Eligible patients (age > or = 18 years) were anemic (hemoglobin level < 11 g/dL), had a nonmyeloid malignancy, and were to receive at least 12 weeks of chemotherapy. Patients were randomly assigned 1:1 to darbepoetin alfa treatment every 3 weeks (500-microg dose) or weekly (2.25-microg/kg) for 15 weeks. We compared red blood cell transfusion incidence among the two arms from week 5 to the end of the treatment phase using a noninferiority study design. Noninferiority was determined if the upper limit of the 95% confidence interval (CI) for the difference in blood transfusions between groups, calculated using Kaplan-Meier methods, did not exceed 12.5%, a margin based on previous placebo-controlled studies. RESULTS A total of 705 patients were randomly assigned, and 672 remained in the study at week 5. Fewer patients in the every-3-week arm than in the weekly arm received blood transfusions from week 5 to the end of the treatment phase (unadjusted Kaplan-Meier estimates = 23% versus 30%, difference = -6.8%; 95% CI = -13.6 to 0.1). Percentages of patients achieving the target hemoglobin level (> or = 11 g/dL, consistent with evidence-based practice guidelines) were 84% (every 3 weeks) and 77% (weekly). The frequency of cardiovascular/thromboembolic adverse events was 8% in both groups, and safety was comparable. CONCLUSIONS Patients with chemotherapy-induced anemia can safely and effectively be treated with 500 microg of darbepoetin alfa every 3 weeks.

Abstract
PURPOSE The objective of this study was to determine the accuracy of (early) response measurements using [18F]-2-fluoro-2-deoxy-D-glucose positron emission tomography (18FDG PET) with respect to survival of patients with stage IIIA-N2 non-small-cell lung cancer (NSCLC) undergoing induction chemotherapy (IC), with a comparative analysis of PET methods. PATIENTS AND METHODS In a prospective multicenter study, PET was performed in patients before IC and after one and three cycles. Computed tomography (CT) was performed before and after IC. Glucose consumption (metabolic rate of glucose [MRglu]) was measured using Patlak graphical analysis and correlated with simplified methods. Mediastinal lymph node (MLN) status was assessed visually. Cox proportional hazards analysis was used to determine the prognostic relevance of CT and PET measures of response with respect to survival. RESULTS Complete PET data sets were available in 47 patients. Median survival was 21 months. MLN status after IC by PET predicted survival (hazard ratio [HR], 2.33; 95% CI, 1.04 to 5.22; P = .04) in contrast with CT (HR, 1.87; 95% CI, 0.81 to 4.30; P = .14). Residual MRglu after IC proved to be the best prognostic factor (HR, 1.95; 95% CI, 1.28 to 2.97; P = .002). Multivariate stepwise analysis showed that PET identified prognostically different strata in patients considered responsive according to CT. Residual MRglu after one cycle selected patients with different outcomes (HR, 2.04; 95% CI, 1.18 to 3.52; P = .01). Simplified quantitative 18FDG PET methods were correlated with Patlak graphical analysis during and after therapy (r > or = 0.90). CONCLUSION 18FDG PET has additional value over CT in monitoring response to IC in patients with stage IIIA-N2 NSCLC, and it seems feasible to predict survival early during IC. Simple semiquantitative and complex PET methods perform equally well.

Abstract
PURPOSE To determine the effect of darbepoetin alfa (DA) on progression-free survival (PFS) and overall survival (OS) in patients with chemotherapy-induced anemia (CIA). PATIENTS AND METHODS Two 16-week randomized, double-blind, placebo-controlled phase III studies of weekly DA in anemic patients with lung cancer (n = 314) or lymphoproliferative malignancies (LPMs; n = 344) undergoing chemotherapy were analyzed with prospectively defined long-term PFS and OS end points. Short-term effects of DA on PFS and OS were analyzed by including two additional 16-week dose-finding, double-blind, placebo-controlled studies in anemic patients with multiple tumor types (n = 405) and LPMs (n = 66). RESULTS Median follow-up is 15.8 months (lung cancer) and 32.6 months (LPM). Median duration of PFS was comparable between DA and placebo: 5.1 months (95% CI, 4.1 to 6.9 months) versus 4.4 months (95% CI, 3.7 to 5.3 months) for lung cancer and 14.2 months (95% CI, 12.2 to 17.5 months) versus 15.9 months (95% CI, 13.1 to 19.0 months) for LPMs. The estimated hazard ratio (HR) of death related to DA use for lung cancer was 0.77 (95% CI, 0.59 to 1.01) and 1.26 (95% CI, 0.92 to 1.71) for LPMs. In the pooled analyses of all four studies (n = 1,129), no differences in PFS or OS were observed between DA and placebo (HR = 0.92; 95% CI, 0.78 to 1.07; and HR = 0.95; 95% CI, 0.78 to 1.16, respectively). CONCLUSION Treatment with DA does not seem to influence PFS or OS in patients with CIA. Prospective, randomized clinical trials will provide additional insights into the effects of DA on PFS and OS in specific tumor types.

Abstract
Aprinocarsen is a specific antisense oligonucleotide inhibitor of protein kinase C-alpha. This study aimed to evaluate the response rate to combination therapy with aprinocarsen, gemcitabine and cisplatin, in chemonaive patients with advanced/metastatic NSCLC. Secondary objectives included comparison of response rate, time to event efficacy parameters, and toxicities on the 2 treatment arms. Patients with stage IV, or stage IIIB disease (N3 and/or pleural/pericardial effusion), were randomized to either control or experimental arm. Patients on both arms received gemcitabine 1250 mg/m2 on days 1 and 8, and cisplatin 80 mg/m2 on day 1 of a 3-week cycle. Additionally, on the experimental arm, aprinocarsen was administered as 2 mg/kg continuous iv infusion on days 1-14, every 21 days. A total of 18 enrolled patients were randomized on the 2 arms. Further enrollment was terminated in March 2003 as a result of a phase III trial suggesting that aprinocarsen did not have an added survival benefit when combined with paclitaxel and carboplatin therapy in patients with NSCLC. Patients received a median of 4 cycles on control arm and 2.5 cycles on experimental arm. The response rate was 16.7% in the experimental arm and 44.4% in the control arm. Most frequent grade 3/4 toxicities were hematologic, with a higher incidence of thrombocytopenia in the experimental arm (87.5% vs. 33.3%). Despite the 14-day continuous infusion schedule, infection rate was not increased in the experimental arm. The present study did not show any advantage, in response rate or secondary endpoints, with aprinocarsen; however, the toxicity was not unduly increased, and aprinocarsen regimen was safely administered.
