RESUMO
BACKGROUND: Chemotherapy is the standard of care for advanced stages of non-small-cell lung cancer (NSCLC). TG4010 is a targeted immunotherapy based on a poxvirus (modified vaccinia virus Ankara) that codes for MUC1 tumour-associated antigen and interleukin 2. This study assessed TG4010 in combination with first-line chemotherapy in advanced NSCLC. METHODS: 148 patients with advanced (stage IIIB [wet] or IV) NSCLC expressing MUC1 by immunohistochemistry, and with performance status 0 or 1, were enrolled in parallel groups in this open-label, phase 2B study. 74 patients were allocated to the combination therapy group, and received TG4010 (10(8) plaque forming units) plus cisplatin (75 mg/m(2) on day 1) and gemcitabine (1250 mg/m(2) on days 1 and 8) repeated every 3 weeks for up to six cycles. 74 patients allocated to the control group received the same chemotherapy alone. Patients were allocated using a dynamic minimisation procedure stratified by centre, performance status, and disease stage. The primary endpoint was 6-month progression-free survival (PFS), with a target rate of 40% or higher in the experimental group. Analyses were done on an intention-to-treat basis. This study is completed and is registered with ClinicalTrials.gov, number NCT00415818. FINDINGS: 6-month PFS was 43·2% (32 of 74; 95% CI 33·4-53·5) in the TG4010 plus chemotherapy group, and 35·1% (26 of 74; 25·9-45·3) in the chemotherapy alone group. Fever, abdominal pain, and injection-site pain of any grade according to National Cancer Institute Common Toxicity Criteria were more common in the TG4010 group than in the chemotherapy alone group: 17 of 73 patients (23·3%) versus six of 72 (8·3%), 12 (16·4%) versus two (2·8%), and four (5·5%) versus zero (0%), respectively. The most common grade 3-4 adverse events were neutropenia (33 [45·2%] of patients in the TG4010 plus chemotherapy group vs 31 [43·1%] in the chemotherapy alone group) and fatigue (18 [24·7%] vs 13 [18·1%]); the only grade 3-4 events that differed significantly between groups were anorexia (three [4·1%] vs 10 [13·9%]) and pleural effusion (none vs four [5·6%]). 38 of 73 patients (52·1%) in the TG4010 plus chemotherapy group and 34 of 72 (47·2%) in the chemotherapy alone group had at least one serious adverse event. INTERPRETATION: This phase 2B study suggests that TG4010 enhances the effect of chemotherapy in advanced NSCLC. A confirmatory phase 2B-3 trial has been initiated.

Several studies have suggested rural health disadvantages. In France, studies on rural-urban patterns of lung cancer survival have yielded conflicting results. The aim of this analysis was to determine whether rural residence was associated with poor survival in three French counties. The database consisted of all primary lung cancer cases diagnosed in 2000 and 2001 collected through the Doubs cancer registry. A degree of rurality, obtained from socio-demographic and farming parameters of the 1999 French census treated with factor analysis, was attributed to each patient according to his/her place of residence. Among the 802 patients, 21% resided in rural areas, 11% were semi-urban inhabitants and 68% were urban residents. Survival differed significantly between these three rurality categories (p=0.04), with 2-year survival rates of 18, 29 and 24%, respectively. Using a Cox model, rural areas were significantly correlated with poor survival as compared with semi-urban areas (OR=1.42; 95% confidence interval=1.06-1.90; p=0.02). There was no survival difference between semi-urban and urban patients (OR=1.18; 95% confidence interval=0.91-1.53; p=0.21). Patient and tumour characteristics, especially stage and staging procedures, as well as first line treatment, did not vary with the degree of rurality. In conclusion, rurality has to be considered as a strong prognostic factor. Several intricate factors might be hypothesized such as increasing time to diagnosis leading to heavier tumour burden, worse treatment compliance and socioeconomic status. Before practical interventions can be proposed, prospective studies are warranted with further definition of rural risk factors for decreased survival in rural lung cancer patients.

PURPOSE: This randomized, double-blind, placebo-controlled phase III study aimed to determine whether thalidomide prolongs survival of patients with extensive-disease small-cell lung cancer (SCLC). PATIENTS AND METHODS: One hundred nineteen patients received two courses of etoposide, cisplatin, cyclophosphamide, and 4'-epidoxorubicin (PCDE). Responder patients who had recovered from chemotherapy toxicity were randomly assigned to receive four additional PCDE cycles plus thalidomide (400 mg daily) or placebo. RESULTS: After the first two PCDE cycles, objective response rate was 81.5%, and 92 patients were randomly assigned to placebo (n = 43) or thalidomide (n = 49). Median exposure duration to placebo was 4.5 months, and median exposure to thalidomide was 4.9 months. Patients treated with thalidomide had a longer survival compared with patients who received placebo, although the difference was not statistically significant (minimal follow-up, 3 years; median survival time, 11.7 v 8.7 months, respectively; log-rank test: hazard ratio [HR] = 0.74; 95% CI, 0.49 to 1.12; P = .16). Patients with a performance status (PS) of 1 or 2 who received thalidomide had a significantly longer survival (HR = 0.59; 95% CI, 0.37 to 0.92; P = .02). The disease also progressed slower in patients with PS of 1 or 2 receiving thalidomide (HR = 0.54; 95% CI, 0.36 to 0.87; P = .02), whereas the difference did not reach statistical significance for the whole population (HR = 0.74; 95% CI, 0.49 to 1.12; P = .15). Neuropathy occurred more frequently in the thalidomide group compared with the placebo group (33% v 12%, respectively). CONCLUSION: Treatment with thalidomide was not associated with a significant improvement in survival of SCLC patients. There was pronounced heterogeneity in survival outcomes between groups of patients. Some benefit was observed among patients with a PS of 1 or 2 (exploratory analyses), deserving further studies targeting angiogenesis in this disease.

PURPOSE: Ixabepilone 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 METHODS: Patients had experienced disease progression after one prior cisplatin- or carboplatin-based chemotherapy regimen. Ixabepilone was administered as a single 32 mg/m(2) 3-hour infusion (77 patients; arm A) or a 6 mg/m(2) 1-hour infusion daily for 5 consecutive days (69 patients; arm B) in a 3-week cycle. RESULTS: The 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). CONCLUSION: Single-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.

BACKGROUND: Lung cancer has the highest mortality-rate per cancer, with an overall 5-year survival <15%. Several non-randomized studies pointed out the high sensitivity of low dose computed tomography (LDCT) to detect early stage lung cancer. In France, Depiscan, a pilot RCT of LDCT versus chest X-ray (CXR), started on October 2002 to determine the feasibility of enrollment by general practitioners (GPs), investigations and diagnostic procedures by university hospital radiologists and multidisciplinary teams, data management by centralized clinical research assistants, and anticipate the future management of a large national trial. METHODS: GPs and occupational physicians (OPs) selected and enrolled 1000 subjects in 1 year. Eligible subjects were asymptomatic males or females aged 50-75 years with a current or former cigarette smoking history of >/=15 cigarettes per day for at least 20 years (former smokers having quit <15 years prior to enrollment). Based to randomization, annual LDCT or CXR screenings were planned at baseline and annually for 2 years. RESULTS: Between October 2002 and December 2004, 765 subjects were enrolled by 89 out of the 232 participating GPs and OPs. Complete clinical and imaging baseline data were available for 621 individuals out of the 765 enrolled, due to 144 noncompliant subjects who withdrew their consent. At least one nodule was detected in 152 out of 336 subjects (45.2%) in the LDCT screening, versus 21 out of 285 subjects (7.4%) in the CXR screening arm. Eight lung cancers were detected in the LDCT arm and one in the CXR arm. DISCUSSION: This pilot trial allows estimating that non-calcified nodules are 10 [6.36-17.07] times more often detected from LDCT than from CXR. However enrollment by GPs was more difficult than expected with 41% active investigators and a high rate (19%) of noncompliant patients. This experience speaks to the need for a high level of GPs formation and a large, coordinated clinical research team in such a trial. TRIAL REGISTRATION NUMBER: 02526.

INTRODUCTION: We designed this phase II trial to evaluate the efficacy and safety of weekly paclitaxel in combination with monthly carboplatin as first-line treatment in elderly patients with advanced non-small cell lung cancer (NSCLC). METHODS: Main eligibility criteria were histologically or cytologically proven stage IIIB or IV NSCLC, age > or =70 years, Eastern Cooperative Oncology Group performance status 0-2, and measurable disease. The 4-week-based chemotherapy regimen consisted of carboplatin infusion (area under the concentration-time curve 6 mg/ml/min) on day 1 and paclitaxel 90 mg/m as a 1-hour infusion on days 1, 8, and 15. Tumor response was evaluated using Response Evaluation Criteria in Solid Tumors criteria, and symptoms were evaluated using the Lung Cancer Symptoms Scale. Analyses were performed on an intention-to-treat basis. RESULTS: From February 2002 to August 2003, 51 patients (median age, 74 years) participated in the study. One complete and 21 partial responses were reported by the independent review committee, leading to an intention-to-treat objective response rate of 43% (95% confidence interval, 30-57%). The median progression-free and overall survivals were 7.5 (95% confidence interval, 6.2-9.4) and 13.6 (95% confidence interval, 7.5-17) months, respectively. Longitudinal evaluation of the Lung Cancer Symptoms Scale demonstrated lack of quality of life modification during the treatment period. Neurotoxicity was mild to moderate, with 6% of patients suffering from a grade 3 or 4 neuropathy. Myelosuppression was the main toxicity; 39% of patients experienced grade 3 or 4 neutropenia, 18% experienced grade 3 anemia, and 8% experienced grade 3 or 4 thrombocytopenia. There was no treatment-related death. CONCLUSIONS: The combination of weekly paclitaxel 90 mg/m administered on days 1, 8, and 15 plus monthly carboplatin area under the curve 6 on day 1 of a 4-week cycle was feasible and active as a first-line treatment for elderly patients with NSCLC with a good safety profile. These results deserve further analysis to compare the standard care for these patients (monotherapies) with this doublet.

PURPOSE: Topotecan (Hycamtin is active in small-cell lung cancer (SCLC). This phase II study investigated the efficacy and safety of topotecan in combination with either cisplatin or etoposide in untreated extensive disease SCLC (ED SCLC). PATIENTS AND METHODS: Patients with untreated ED SCLC were randomised to treatment with T/C (topotecan 1.25mg/(m(2)day) IV days 1-5, cisplatin 50mg/m(2) IV day 5; 41 patients) or T/E (topotecan 0.75 mg/(m(2)day) IV days 1-- 5, etoposide 60 mg/(m(2)day) IV days 1-5; 41 patients) every 21 days. Response was evaluated by strict radiological criteria. RESULTS: Response rates were similar for T/C (63.4%, 95% CI: 48.7-78.2%) and T/E (61.0%, 95% CI: 46-76%) with one patient in each arm who underwent complete response. Median survival was 41.6 weeks (9.6 months) for the T/C group and 43.7 weeks (10.1 months) for the T/E group. Toxicity was primarily haematological in both groups. The proportion of patients with grades 3-4 anaemia was significantly higher in the T/C arm (46.4%) versus 20% with the T/E arm (p=0.018). The proportion of patients with grade 4 neutropenia was not significantly lower with T/C (56.1%) than with T/E (65.0%, p=0.41), as was the incidence of associated events such as sepsis (T/C: 0%; T/E: 9.8%, p=0.11). The overall deliverability of either regimen was similar. The most frequent non-haematological adverse experiences of all grades per patient were nausea (T/C: 43.9%; T/E: 36.6%), and alopecia (T/C: 39.0%; T/E: 56.1%). Topotecan did not appear to increase the frequency of adverse events specifically associated with cisplatin. CONCLUSION: This study showed T/C and T/E to be effective and well tolerated in patients with ED SCLC and further evaluation of topotecan in first line SCLC is warranted.

BACKGROUND: Prolongation of chemotherapy duration, usually referred to as maintenance chemotherapy, has been considered as an approach to improve survival of patients with advanced non-small-cell lung cancer (NSCLC). If the maintenance regimen differs from the induction regimen, patients will receive not only higher total doses of chemotherapy but also earlier delivery of non-cross-resistant agents. We conducted a randomized trial to compare maintenance vinorelbine therapy with observation in previously untreated patients who responded to induction treatment with mitomycin-ifosfamide-cisplatin (MIC). METHODS: Patients with stage IIIB NSCLC were treated with two monthly MIC cycles followed by radiotherapy; those with "wet" stage IIIB (pleural or pericardial involvement), with stage IIIB with supraclavicular node involvement, or stage IV (i.e., metastatic) NSCLC were treated with four monthly MIC cycles. Patients who responded to induction treatment were randomly assigned to receive intravenous vinorelbine at a dose of 25 mg x m(-2) x wk(-1) for 6 months or no further treatment. Survival comparisons used the log-rank test and the Cox regression adjusted for stage. All statistical tests were two-sided. RESULTS: A total of 573 patients were registered, of whom 227 responded to induction treatment and 181 were randomly assigned (91 to maintenance vinorelbine and 90 to observation) between January 1994 and March 2000. One- and 2-year survival rates were 42.2% and 20.1% in the vinorelbine arm and 50.6% and 20.2% in the observation arm, respectively (log-rank P = .48). The hazard ratio of survival after adjustment on stage, in the vinorelbine arm relative to the observation arm, was 1.08 (95% confidence interval = 0.79 to 1.47; P = .65). There was also no difference between arms in progression-free survival (log-rank P = .32). CONCLUSION: Maintenance vinorelbine did not improve survival of patients with advanced NSCLC who responded to induction MIC treatment. Nevertheless, other agents, including docetaxel and targeted agents, should be evaluated as maintenance agents before the concept is abandoned.

PURPOSE: This randomized phase II multicenter trial aimed at evaluating the efficacy and safety of the 4-week versus 3-week schedules of gemcitabine monotherapy in previously untreated elderly patients with advanced non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: Chemonaive patients with stage IIIB or IV NSCLC, and age between 70 and 90 years, were randomized to receive gemcitabine dose of either 1000 mg/m2 on days 1, 8, 15, every 28 days (arm Q4W), or 1125 mg/m2 on days 1 and 8, every 21 days (arm Q3W). RESULTS: From June 1999 to January 2001, 81 patients (42 on arm Q4W; 39 on arm Q3W) were included. The median age was 75 on both arms; most patients (82.7%) were male, and had a Karnofsky performance status of 80 or 90 (76.5%). For arms Q4W and Q3W, respectively, the median time to treatment failure was 83 days (95% CI, 69-98 days) versus 92 days (95% CI, 63-113), and the median survival was 154 days (95% CI, 108-227) versus 205 days (95% CI, 125-344). The objective response rate was higher on arm Q3W (28.2%) than on arm Q4W (14.3%). Total number of cycles administered was 132 on arm Q4W (median 3, range 1-10 cycles) and 169 on arm Q3W (median 4, range 1-9 cycles). Patients on arm Q4W and Q3W, respectively, received 100.1 and 99.8% of the planned weekly mean dose. The most common grade, three to four toxicities, was neutropenia (17.1% on arm Q4W versus 18.9% on arm Q3W) and thrombocytopenia (12.2% on arm Q4W versus 2.6% on arm Q3W). CONCLUSION: Although both 3- and 4-week gemcitabine regimens were safely and effectively administered in chemonaive elderly patients with advanced NSCLC, the 3-week schedule appears to be the more convenient for this population. Moreover, even if this is only a phase II study this 3-week schedule appears to be at least as efficient as the 4-week regimen.

As the incidence of primary lung cancer in women seems to be increasing in parallel with that of smoking, we conducted an exhaustive epidemiological study in 137 hospitals in 2000. We identified 904 women with proven primary lung cancer (mean age 63.9 years), many of whom have never smoked (32.3%), particularly in cases of adenocarcinoma (43.4%). Small cell cancer accounted for 16.1% of cases. Adenocarcinomas were the most frequent (45.3%) of the non-small cell lung cancer (NSCLC), followed by squamous cell (23.4%), large cell (11.6%) and bronchoalveolar (1.9%) carcinomas. About one third (32.2%) of NSCLC were stage III and 48.1% were stage IV. Over half of all adenocarcinomas were stage IV. According to multivariate analysis, adenocarcinoma is related to less smoking and younger age. In conclusion, many women affected by lung cancer have never smoked. Adenocarcinoma appears to be the most frequent form and more often at a metastatic stage.

CONTEXT: The "Standards, Options and Recommendations" (SOR) project, started in 1993, is a collaboration between the Federation of French Cancer Centers (FNCLCC), the 20 French cancer centers and specialists from French public university and general hospitals and private clinics. Its main objective is the development of clinical practice guidelines to improve the quality of health care and outcome for cancer patients. The methodology is based on literature review and critical appraisal by a multidisciplinary group of experts, with feedback from specialists in cancer care delivery. OBJECTIVES: To develop, according to the definitions of the Standards, Options and Recommendations, clinical practice guidelines for the management of non small cell lung carcinoma patients. METHODS: Data were identified by searching Medline and the personal reference lists of members of the expert groups, then submitted for review to independent reviewers. This is a short version of the SOR guideline covering diagnosis, treatment and follow-up and includes the algorithms for the management of patients with non-small cell lung cancer.

The main objective is the development of clinical practice guidelines to improve the quality of health care and the outcome of cancer patients. The methodology is based on a literature review and critical appraisal by a multidisciplinary group of experts, with feedback from specialists in cancer care delivery. OBJECTIVES: To develop clinical practice guidelines for non small cell lung cancer patients according to the definitions of the Standards, Options and Recommendations project. METHODS: Data were identified by searching Medline , web sites, and using the personal reference lists of members of the expert groups. Once the guidelines were defined, the document was submitted for review to independent reviewers. RESULTS: This article presents the chapter "Prognosis significance of oncogenes and tumor suppressor genes" from the full report "Standards, Options and Recommendation for non small cell lung cancer" validated in August 2000. The main recommendations are: 1) No clear clinical prognostic value of oncogenes and tumor suppressor genes (p53, bcl-2, Ki-ras, c-erbB-2, Rb, p16) in non small cell lung cancer, can be established from the available evidences (standard, level of evidence C). 2) Prospective multicenter studies should be performed to assess prognostic significance of oncogenes and tumor suppressor genes in non small cell lung cancer.

PURPOSE: To evaluate whether preoperative chemotherapy (PCT) could improve survival in resectable stage I (except T1N0), II, and IIIA non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: A randomized trial compared PCT to primary surgery (PRS). PCT consisted of two cycles of mitomycin (6 mg/m(2), day 1), ifosfamide (1.5 g/m(2), days 1 to 3) and cisplatin (30 mg/m(2), days 1 to 3), and two additional postoperative cycles for responding patients. In both arms, patients with pT3 or pN2 disease received thoracic radiotherapy. RESULTS: Three hundred fifty-five eligible patients were randomized. Overall response to PCT was 64%. There were two preoperative toxic deaths. Postoperative mortality was 6.7% in the PCT arm and 4.5% in the PRS arm (P =.38). Median survival was 37 months (95% confidence interval [CI], 26.7 to 48.3) for PCT and 26.0 months (95% CI, 19.8 to 33.6) for PRS (P =.15). Survival differences between both arms increased from 3.8% (95% CI, 1.3% to 25.1%) at 1 year to 8.6% (95% CI, 2.64% to 24.4%) at 4 years. A quantitative interaction between N status and treatment was observed, with benefit confined to N0 to N1 disease (relative risk [RR], 0.68; 95% CI, 0.49 to 0.96; P =.027). After a nonsignificant excess of deaths during treatment, the effect of PCT was significantly favorable on survival (RR, 0.74; 95% CI, 0.56 to 0.99; P =.044). Disease-free survival time was significantly longer in the PCT arm (P =.033). CONCLUSION: Although impressive differences in median, 3-year, and 4-year survival were observed, they were not statistically significant, except for stage I and II disease.
