      Background
      Customization is feasible in adjuvant setting (tissue availability). SCAT trial has completed planned recruitment with 500 p. For resected NSCLC with nodal involvement adjuvant platinum-based CT improves outcomes but survival remains suboptimal. Compliance may be a key issue for efficacy in adjuvant setting. mRNA BRCA1 levels are prognostic in early NSCLC and could be a predictive marker for CT activity. In advanced disease patients with low BRCA1 benefit from cisplatin doublets meanwhile p with high levels attained longer survival with taxanes.

      Methods
      Phase III trial testing 4 cycles non-selected vs customized adjuvant CT. Entry criteria: NSCLC, R0 resection, pN1 or pN2, KI > 70, recovered from surgery, adequate hematologic, renal and liver functions, no prior CT or RT, age > 18 y, informed consent. Stratification: N1 vs N2, histology (squamous vs non-squamous), resection (lobectomy vs pneumonectomy). Central lab mRNA BRCA1 levels and quartile distribution. Primary end-point: OS. Secondary end-points: DFS, toxicity, recurrence pattern. Design: R: 1:3. Control treatment: Cis-Docetaxel (CD). Experimental arm: Q1: Cis-Gemcitabine (CG); Q2-3: Cis-Docetaxel; Q4: Docetaxel (D). PORT in pN2 patients. Compliance treatment and toxicity profile analyzed by arm and correlation with potential prognostic factors explored

      Results

      Conclusion
      Planned trial recruitment achieved with median f-u 18.6 m. Majority of resected NSCLC showed low levels expression BRCA1. Adenocarcinoma lower levels than Squamous. Safety profiles differences observed between treatment schedules: neutropenic fever (CD), nausea/vomits (CG). Customized treatment requires less dose-reductions. Trend to poor compliance with Cis-Doc. No relation between extensión of surgery and adjuvant Tx compliance . Compliance CT significantly lower for age > 70 y. Low compliance for PORT.

      MO24.08 - Survival outcomes among NSCLC patients in Europe receiving platinum-based therapies as first-line treatment: results from the FRAME observational study (ID 1944)

      11:10 - 11:15  |  Author(s): J.D. Castro Carpeño

      • Abstract
      • Presentation
      • Slides

      Background
      FRAME was a European non-interventional prospective observational study of patients with advanced or metastatic non-small cell lung cancer (NSCLC) initiating platinum-based therapies as first-line treatment (FLT).

      Methods
      Patients were enrolled between April 2009 and February 2011. Consenting adult NSCLC (Stage III/IV) patients initiating FLT with a platinum-based doublet chemotherapy, with or without an additional targeted agent, were eligible for the study. The choice of FLT was left to physician discretion, as per routine clinical practice. The primary objective of FRAME was to evaluate overall survival (OS) among different platinum-based treatment cohorts in patients with and without additional targeted therapy. Secondary objectives included the evaluation of OS in patients with different histological subtypes of NSCLC. Survival outcomes were assessed using Kaplan-Meier analysis, and unadjusted estimates are presented.

      Results
      A total of 1564 eligible patients from 11 EU countries were observed. Patient cohorts were: pemetrexed + platinum, gemcitabine + platinum, vinorelbine + platinum, taxanes + platinum and other therapy + platinum. Table 1 shows a subset of baseline patient characteristics, which varied across several parameters in the treatment cohorts, including age, performance status (PS), stage and histology. The median OS across the 4 main treatment cohorts was 10.3 months (95% CI: 9.5-11.2). A subset of overall survival estimates in the different treatment cohorts is shown in Table 1.

      P1.11-046 - Women with lung cancer harboring epidermal growth factor (EGFR) mutations: prevalence, clinical characteristics and EGFR tyrosine kinase (TKI) treatment-related outcomes. Results from the Spanish WORLD07 database (ID 3078)

      09:30 - 09:30  |  Author(s): J.D. Castro Carpeño

      • Abstract

      Background
      EGFR mutations define a distinct molecular subset of non-small-cell lung cancer patients (p). Prevalence, baseline clinical characteristics and outcomes for women with lung cancer harboring EGFR mutations would be of interest.

      Methods
      We analyzed the clinical characteristics of women with lung cancer harboring EGFR mutations included in the WORLD07, a Spanish prospective, multicenter, epidemiologic female-specific e-database.

      Results
      A total of 2081 newly-diagnosed women with lung cancer from 38 Spanish centers were included in the WORLD07 e-database from October/2007 to October/2012. Overall 915 p were evaluated for EGFR mutation status, and 342 of them were found to have EGFR mutation (16% of all p in the e-database, 37% of p tested). EGFR-mutated p characteristics: median age 64.6 years; 86% had offspring; 8.2% had used oral contraceptives; smoking habit: 72% never smokers, 14% current smokers, 13% former smokers; for those never smokers, second-hand smokers 35%; histology: 91% adenocarcinoma, 1.5% squamous cell carcinoma, 2% large-cell carcinoma, 5% other; EGFR mutation type: 60% deletions in exon 19, 32.5% L858R mutations, 8% exon 20 mutations, 1% exon 18 mutations, 14% unknown. Sixty-nine percent of p had stage IV disease. A total of 184 EGFR mutated p received an oral EGFRTKI as 1[st] line (ECOG PS: 0 in 24%, 1 in 53%, 2 in 13%, 4 in 4%, unknown in 5%) achieving a 59% response rate (RR), 20% stable disease (SD), 10% progression (PD) and 11% not evaluable (NE); with a median follow-up of 12 months, median overall survival for these p was 21 months. A total of 72 p received an EGFRTKI as 2[nd] line with 37% RR, 34% SD, 19% PD and 10% NE. Only 16 p received an EGFRTKI as 3[rd] line, achieving a 38% RR, 19% SD, 31% PD and 12.5% NE. For those EGFR mutated women receiving an EGFRTKI as 1[st] line, RR to an EGFRTKI was 70% in those women harboring deletion in exon 19, and 45% in those with L858R mutation; median overall survival was 24 months in those with deletion in exon 19, and 17 months in those with L858R mutation. Response rate to an EGFRTKI as 1[st] line treatment was 59% in never-smoker p and 53% in current-smoker/former-smoker p with a median overall survival of 23 months and 21 months, respectively.

      Conclusion
      According to our prospective e-database of women with lung cancer, not selected for clinical trials and including all histologies, a high proportion harbor an EGFR mutation (16% of non-selected women, 37% of those tested). The vast majority of women with lung cancer harboring EGFR mutation are never smokers, have adenocarcinoma histology and outcomes similar to those previously reported in the literature. Additional epidemiologic and treatment data will be presented at the meeting.

      P2.22-008 - Analysis of family history of cancer in women with lung cancer (WLC) from the Spanish WORLD07 database (ID 2430)

      09:30 - 09:30  |  Author(s): J.D. Castro Carpeño

      • Abstract

      Background
      Gender differences in lung cancer (LC) have been reported, but with many unresolved issues . Family history of cancer might play an important role in lung cancer, especially in never-smoker patients. The aim of this study was to analyze potential clinical, molecular and epidemiological differences between WLC with or without family history of cancer.

      Methods
      WORLD07 is a Spanish prospective, multicenter, epidemiologic female-specific LC database sponsored by ICAPEM, a professional association committed with WLC research. Clinicopathologic data, tumor genotype, family and personal history of cancer were collected and analyzed in order to detect differences between both groups.

      Results
      From October/2007 to November/2012, 2081 WLC were included in an e-database from 32 centers. Family history of cancer was common (49.4%, in first-degree was 77%), family history of lung cancer was present in 33%, of breast cancer in 25% and of colorectal cancer in 17%. No differences in median age of diagnosis of LC, previous hormonal therapy, number of children, menstrual status, tumor histology or stage at diagnosis were observed between WLC with or without family history of cancer. WLC with family history of cancer were ever smokers in a higher percentage (63% vs 56%, p=0.006), with no differences in passive smokers. The presence of EGFR mutations was similar in WLC with family history of cancer versus WLC without family history (38% vs 37%), although WLC patients with family history of cancer had a higher rate of exon 21 mutation (36% vs 28%), both in smokers WLC (32% vs 16%, p=0.220) and in never smokers WLC (43% vs 32%, p=0.094). The median overall survival was 25 months (CI95% 21.0-29.0) for WLC with family history of cancer and 22.0 months (CI95% 19.4-24.5) for patients without family history of cancer (p=0.027). Of note, the median overall survival was 34.8 months (CI95% 22.9-46.6) for WLC with family history of LC and 22.5 months (CI95% 20.5-24.5) for patients without family history of LC (p< 0.001).

      Conclusion
      The presence of familiar history of cancer in WLC patients included in the WORLD07 database was high (49.4%), being lung cancer the most common, followed by breast cancer. No clinical or pathologic characteristic differences were observed between patients with or without family history of cancer. The presence of EGFR mutations was similar, although WLC patients with family history of cancer had a higher rate of exon 21 mutation. The median overall survival was significantly higher in WLC patients with family history of cancer and LC. Family history of cancer, especially of LC, might have a role in LC development and deserves further studies focused in inherited genetic alterations related with an increased susceptibility to LC.

      P3.10-002 - Resource utilization of NSCLC patients receiving platinum-based therapies across Europe; results from the FRAME observational study (ID 183)

      09:30 - 09:30  |  Author(s): J.D. Castro Carpeño

      • Abstract

      Background
      FRAME was a non-interventional, prospective observational study of advanced or metastatic non-small cell lung cancer (NSCLC) patients initiating first-line treatment (FLT) with platinum-based therapies in a routine practice setting across 11 European countries.

      Methods
      Patient enrollment occurred between April 2009 and February 2011. Consenting adults with Stage IIIB or IV NSCLC receiving platinum-based doublet chemotherapy with or without an additional targeted agent as FLT were eligible for this study. Patients were under routine treatment for NSCLC by their doctors and treatment choice and resource use were at the discretion of the treating physician. Secondary objectives of the study included determining resource use during FLT. Hospitalizations, outpatient visits, concomitant therapy use, transfusions and the use of colony stimulating factors (CSFs) are reported here. Cohorts were not adjusted for multivariate parameters prohibiting statistical comparisons.

      Results
      Evaluable patients (n=1564) were categorized into 4 main cohorts based on their FLTs: pemetrexed + platinum (n=569), gemcitabine + platinum (n=360), taxanes + platinum (n=295) or vinorelbine + platinum (n=300). Forty of the evaluable patients received other platinum-doublet treatments and were excluded from the analyses presented here.Across the four main cohorts, 55% of patients were hospitalized.A majority (61%) of hospitalizations were preplanned (71% in the pemetrexed cohort, 45% in the gemcitabine cohort, 67% in the taxanes cohort and 53% in the vinorelbine cohort). Among the unplanned hospitalizations, 54% were related to an adverse event (54% in the pemetrexed cohort, 54% in the gemcitabine cohort, 55% in the taxanes cohort, and 55% in the vinorelbine cohort). The mean (95%-confidence interval) duration of hospitalizations was 13 days (11.6 to 14.6) for pemetrexed (median=9 days), 11 days (9.4 to 12.8) for gemcitabine (median=7 days),17 days (14.0 to 19.7) for taxanes (median=12 days), and 13 days (11.3 to 15.0) for vinorelbine (median=9 days). Nearly half of patients (47%) were seen in an outpatient setting with most outpatient visits (82%)planned for scheduled treatments. Nineteen percent of patients received ≥1 transfusion (16% in the pemetrexed cohort, 24% in the gemcitabine cohort, 15% in the taxanes cohort and 24% in the vinorelbine cohort). Nearly all (94%) of these patients received packed red blood cells. Nineteen percent of patients received ≥1 colony stimulating factor (CSF), which included G-CSF (69%), or erythropoietin (39%). During therapy, 82% of patients used antiemetics and antinauseants, 58% used steroids, 40% used analgesics, and 24% used antibiotics. Twenty-eight percent of patients received radiation during FLT and most often radiation was delivered concurrently with chemotherapy (66% overall, 66% in the pemetrexed cohort, 54% in the gemcitabine cohort, 68% in the taxanes cohort, and 73% in the vinorelbine cohort).

      Conclusion
      The FRAME study provides unique, real-life data reflecting prospectively collected information on resource use not accessible in a clinical trial setting. This study revealed several important findings regarding real-world resource use during NSCLC therapy including data on hospitalizations, outpatient visits, transfusions, concomitant treatments, and radiation.
