Chest CT scan plus x-ray versus chest x-ray for the follow-up of completely resected non-small-cell lung cancer (IFCT-0302): a multicentre, open-label, randomised, phase 3 trial.

BACKGROUND: Even after resection of early-stage non-small-cell lung cancer (NSCLC), patients have a high risk of developing recurrence and second primary lung cancer. We aimed to assess efficacy of a follow-up approach including clinic visits, chest x-rays, chest CT scans, and fibre-optic bronchoscopy versus clinical visits and chest x-rays after surgery for resectable NSCLC. METHODS: In this multicentre, open-label, randomised, phase 3 trial (IFCT-0302), patients aged 18 years or older and after complete resection of pathological stage I-IIIA NSCLC according to the sixth edition of the TNM classification were enrolled within 8 weeks of resection from 122 hospitals and tertiary centres in France. Patients were randomly assigned (1:1) to CT-based follow-up (clinic visits, chest x-rays, thoraco-abdominal CT scans, and fibre-optic bronchoscopy for non-adenocarcinoma histology) or minimal follow-up (visits and chest x-rays) after surgery for NSCLC, by means of a computer-generated sequence using the minimisation method. Procedures were repeated every 6 months for the first 2 years and yearly until 5 years. The primary endpoint was overall survival analysed in the intention-to-treat population. Secondary endpoints, also analysed in the intention-to-treat population, included disease-free survival. This trial is registered with ClinicalTrials.gov, NCT00198341, and is active, but not enrolling. FINDINGS: Between Jan 3, 2005, and Nov 30, 2012, 1775 patients were enrolled and randomly assigned to a follow-up group (888 patients to the minimal follow-up group; 887 patients to the CT-based follow-up group). Median overall survival was not significantly different between follow-up groups (8·5 years [95% CI 7·4-9·6] in the minimal follow-up group vs 10·3 years [8·1-not reached] in the CT-based follow-up group; adjusted hazard ratio [HR] 0·95, 95% CI 0·83-1·10; log-rank p=0·49). Disease-free survival was not significantly different between follow-up groups (median not reached [95% CI not estimable-not estimable] in the minimal follow-up group vs 4·9 [4·3-not reached] in the CT-based follow-up group; adjusted HR 1·14, 95% CI 0·99-1·30; log-rank p=0·063). Recurrence was detected in 246 (27·7%) of 888 patients in the minimal follow-up group and in 289 (32·6%) patients of 887 in the CT-based follow-up group. Second primary lung cancer was diagnosed in 27 (3·0%) patients in the minimal follow-up group and 40 patients (4·5%) in the CT-based follow-up group. No serious adverse events related to the trial procedures were reported. INTERPRETATION: The addition of thoracic CT scans during follow-up, which included clinic visits and chest x-rays after surgery, did not result in longer survival among patients with NSCLC. However, it did enable the detection of more cases of early recurrence and second primary lung cancer, which are more amenable to curative-intent treatment, supporting the use of CT-based follow-up, especially in countries where lung cancer screening is already implemented, alongside with other supportive measures.

Similar survival rates with first-line gefitinib, gemcitabine, or docetaxel in a randomized phase II trial in elderly patients with advanced non-small cell lung cancer and a poor performance status (IFCT-0301).

OBJECTIVES: We evaluated the impact of age in a randomized phase II trial that compared three first-line drugs in elderly patients with advanced non-small cell lung cancer (NSCLC) and a poor performance status (PS). MATERIALS AND METHODS: Patients with advanced NSCLC with a PS of 2 or 3 were enrolled into a multicenter randomized trial: arm A, gefitinib; arm B, gemcitabine; and arm C, docetaxel. We performed subgroup analyses according to age. RESULTS: Between December 2004 and June 2007, 127 patients were enrolled. Analyses were performed between the two subgroups aged <70years (younger, n=56) and ≥70years (older, n=71). Patients mainly had adenocarcinoma (46% young vs. 51%: elderly), of which 62% vs. 75% had a PS of 2, respectively. Significantly more elderly patients were women and non-smokers, and there was a non-significant trend towards more PS-2 among the elderly. Progression-free survival (PFS) was 1.4months (95% CI: 1.1-1.9) for younger compared to 2.3months (95% CI: 2.1-2.9) for elderly patients. Overall survival (OS) was 2.0months (95% CI: 1.5-2.4) and 3.7months (95% CI: 2.4-4.8), respectively. Toxicity did not differ between younger and older patients. NSCLC was better controlled in elderly patients after three cycles of monotherapy compared to younger patients (p=0.034). When adjusted for stratification criteria, age was the main prognostic factor for PFS. Adjusted HRs for PFS was 0.57 (95% CI: 0.38-0.85) for the elderly compared to patients aged <70years (p=0.004). CONCLUSIONS: Older patients had a decreased risk of progression/death compared to younger patients. Single-agent chemotherapy can be considered for patients aged ≥70years with a PS of 2.

A randomised trial comparing preoperative to perioperative chemotherapy in early-stage non-small-cell lung cancer (IFCT 0002 trial).

HYPOTHESIS: There will be a detectable increase in overall survival (OS) using preoperative (PRE) as opposed to perioperative (PERI) chemotherapy in resectable StageI-II non-small-cell lung cancer (NSCLC). METHODS: This multicenter, open-label, randomised trial with a 2×2 factorial design first compared two chemotherapy strategies (PRE versus PERI), then two chemotherapy regimens (gemcitabine-cisplatin [GP] versus paclitaxel-carboplatin [TC]). The PRE group received two preoperative cycles followed by two additional preoperative cycles, while the PERI group underwent two preoperative cycles followed by two postoperative cycles, the 3rd and 4th cycles being given only to responders in both cases. RESULTS: A total of 528 patients were randomised, 267 of which were assigned to the PRE group and 261 to the PERI group. Three-year OS did not differ between the two groups (67.4% and 67.7%, respectively; hazard ratio (HR)=1.01 [0.79-1.30], p=0.92), nor did 3-year disease-free survival, response rates, toxicity, or postoperative mortality. Pathological complete response was observed in 22 (8.2%) and 16 patients (6.1%), respectively. Although quality of life did not differ significantly, chemotherapy compliance was significantly higher in the PRE group. The proportion of responders who received Cycles 3 and 4 was significantly higher in the PRE group (90.4% versus 75.2%, p=0.001). In responders, the dose intensity of Cycles 3 and 4 was higher in the PRE group than in the PERI group (mean relative dose intensity of 90.4% versus 82.6%, respectively; p=0.0007). There was no difference between GP and TC in 3-year OS (HR=0.97 [95% confidence interval (CI): 0.76-1.25], p=0.80) or response rates. However, the regimens' toxicity profiles differed. CONCLUSIONS: This study failed to demonstrate any difference in survival between patients receiving preoperative and perioperative chemotherapy in early-stage NSCLC. The increase from two to four preoperative chemotherapy cycles did not increase the pathological response rate.

An apoptosis methylation prognostic signature for early lung cancer in the IFCT-0002 trial.

PURPOSE: To evaluate prognostic and predictive molecular biomarkers in early-stage non-small cell lung carcinoma (NSCLC) receiving neoadjuvant chemotherapy. EXPERIMENTAL DESIGN: The IFCT-0002 trial compared two neoadjuvant regimens in 528 stages I to II NSCLC patients. DNA extraction of snap-frozen surgical samples taken from 208 patients receiving gemcitabine-cisplatin or paclitaxel-carboplatin regimens allowed for the identification of 3p allelic imbalance, Ras association domain family 1A (RASSF1A) and death-associated protein kinase 1 (DAPK1) promoter methylation, and epidermal growth factor receptor, K-ras, and TP53 mutations. Multivariate analysis identified prognostic and predictive effects of molecular alterations. A Bootstrapping approach was used to assess stability of the prognostic models generating optimism corrected indexes. RESULTS: RASSF1A methylation correlated significantly with shorter disease-free survival (DFS; adjusted HR = 1.88, 95% CI: 1.25-2.82, P = 0.0048) and shorter median overall survival (OS; adjusted HR = 2.01, 95% CI: 1.26-3.20, P = 0.020). A computed bootstrap resampling strategy led to a prognostic model, including RASSF1A, DAPK1, and tumor stage, dividing patients into three prognostic groups, with median OS ranging from 34 months for high-risk patients (HR for death = 3.85, 95% CI: 1.79-6.40) to more than 84 months for moderate (HR = 1.85, 95% CI: 0.97-3.52) and low-risk patients (reference group; P = 0.00044). In addition, RASSF1A methylation predicted longer DFS in patients treated with paclitaxel-carboplatin compared with gemcitabine-cisplatin (adjusted HR = 0.47, 95% CI: 0.23-0.97, P(interaction) = 0.042). CONCLUSIONS: Following neoadjuvant chemotherapy, RASSF1A methylation negatively impacted prognosis of early-stage NSCLC. Along with DAPK1 methylation and tumor stage, RASSF1A methylation allowed definition of three subgroups with strikingly different prognosis. Conversely, significantly longer DFS following paclitaxel-based neoadjuvant chemotherapy for patients whose tumors showed RASSF1A methylation suggested its predictive interest in stages I and II NSCLC.

Therapeutic vaccination with TG4010 and first-line chemotherapy in advanced non-small-cell lung cancer: a controlled phase 2B trial.

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.

Complete response following preoperative chemotherapy for resectable non-small cell lung cancer: accuracy of clinical assessment using the French trial database.

BACKGROUND: Pathologic complete response (CR) to preoperative chemotherapy has been shown to be a strong prognostic factor in resected non-small cell lung cancer (NSCLC). This preoperative setting offers the opportunity to evaluate the clinical prediction of CR by investigators and an evaluation committee (EC) using the "gold standard" pathologic examination as the reference. The only published large randomized trial of preoperative chemotherapy (to our knowledge), the French neoadjuvant study, constitutes an interesting database to evaluate CT scan-based CR assessment. STUDY OBJECTIVES AND DESIGN: The French trial compared mitomycin-ifosfamide-cisplatin followed by surgery with surgery alone in stage I (except T1N0) to IIIa resectable NSCLC. Response was prospectively assessed in all patients receiving preoperative chemotherapy by the investigator in charge of the patient and by an EC, and was compared with pathologic postoperative data. RESULTS: In the preoperative chemotherapy study, 167 patients were operated on. Nineteen patients were found to have a pathologic CR. Only seven patients were classified as having a CR by investigators and five patients by the EC. Evaluation of CR was correct in six of these seven cases and in three of these five cases, respectively. Sensitivity of the CR diagnosis was 31.6% for investigators and 15.8% for the EC. Specificities of the CR diagnosis were 99.4% and 98.8%, respectively. Positive predictive values were 85.7% and 60%, respectively. Negative predictive values were 91.9% and 90.1%, respectively. Accuracies were 91.6% and 89.2%, respectively. CONCLUSION: Investigator assessment of CR was highly predictive of pathologic CR. However, this study showed that clinical CT scan-based assessment, whether performed by investigators or the EC, underestimated the frequency of CR after preoperative chemotherapy in resectable NSCLC.

Rupture of multiple tendons after levofloxacin therapy.

An 80-year-old man treated by levofloxacin developed multiple tendon ruptures. His symptoms resolved over 9 months after levofloxacin discontinuation. Nasal corticosteroid therapy, aging and chronic respiratory insufficiency were probably predisposing factors in this patient.

Preoperative chemotherapy followed by surgery compared with primary surgery in resectable stage I (except T1N0), II, and IIIa 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.
