Purpose To compare efficacy of pemetrexed versus pemetrexed plus carboplatin in pretreated patients with advanced non–small-cell lung cancer (NSCLC). Patients and Methods Patients with advanced NSCLC, in progression during or after first-line platinum-based chemotherapy, were randomly assigned to receive pemetrexed (arm A) or pemetrexed plus carboplatin (arm B). Primary end point was progression-free survival (PFS). A preplanned pooled analysis of the results of this study with those of the NVALT7 study was carried out to assess the impact of carboplatin added to pemetrexed in terms of overall survival (OS). Results From July 2007 to October 2009, 239 patients (arm A, n = 120; arm B, n = 119) were enrolled. Median PFS was 3.6 months for arm A versus 3.5 months for arm B (hazard ratio [HR], 1.05; 95% CI, 0.81 to 1.36; P = .706). No statistically significant differences in response rate, OS, or toxicity were observed. A total of 479 patients were included in the pooled analysis. OS was not improved by the addition of carboplatin to pemetrexed (HR, 90; 95% CI, 0.74 to 1.10; P = .316; P heterogeneity = .495). In the subgroup analyses, the addition of carboplatin to pemetrexed in patients with squamous tumors led to a statistically significant improvement in OS from 5.4 to 9 months (adjusted HR, 0.58; 95% CI, 0.37 to 0.91; P interaction test = .039). Conclusion Second-line treatment of advanced NSCLC with pemetrexed plus carboplatin does not improve survival outcomes as compared with single-agent pemetrexed. The benefit observed with carboplatin addition in squamous tumors may warrant further investigation.

e19086 Background: In the last few years, the treatment of non-small cell lung cancer (NSCLC) has been dramatically changed with the introduction of EGFR TK (Epidermal Growth Factor Tyrosine Kinase) inhibitors. Given its objectivity and the benefits derived by patients, overall survival (OS) has been historically considered the most important therapeutic objective in advanced NSCLC. However, little is known about postprogression survival (PPS) in NSCLC. This study evaluates the correlation between response to erlotinib and post progression survival (i.e. the time between disease progression and death) to estimate the impact of this drug on overall survival. Methods: We retrospectively analyzed 68 NSCLC unselected patients consecutively treated with second or third line erlotinib at our institution from 2007 to 2010, including in the responder group patients who progressed after stable disease on erlotinib for at least six months (n=20). The relationship between OS and PPS was evaluated by standard statistical tests. P-values <0.05 were considered statistically significant. Results: Survival was significantly prolonged in responders patients (18.6 vs 11.3) suggesting the important role of EGFR TK inhibitors in NSCLC management. In addition a significant increase of PPS was recorded in these patients (9.1 vs 4.6 p=0.02), allowing to perform further therapy lines to better control cancer evolution. Conclusions: These data underline the key role of EGFR in NSCLC growth and progression and the impact of erlotinib in cancer control evolution. Post progression therapy influence the effect on overall survival. This analysis suggests that a treatment strategy incorporating all active agents over the course of disease optimizes OS. Further investigations will be needed in selected patients harboring EGFR-activating mutations to better define the role of PPS as new indicator of erlotinib efficacy.

Purpose We employed meta-analytic techniques to evaluate early (E) versus late (L) timing of thoracic radiation therapy (RT) in limited-stage small-cell lung cancer (LS-SCLC). In addition, we assessed the impact of radiation fractionation and chemotherapeutic regimen on timing. Methods Randomized trials published after 1985 addressing timing of RT relative to chemotherapy in LS-SCLC were included. Trials were analyzed by risk ratio (RR), risk difference, and number-needed-to-treat methods. Results Overall survival (OS) RRs for all studies were 1.17 at 2 years (95% CI, 1.02 to 1.35; P = .03) and 1.13 at 3 years (95% CI, 0.92 to 1.39; P = .2), indicating a significantly increased 2-year survival for ERT versus LRT patients and suggestive of a similar trend at 3 years. Subset analysis of studies using hyperfractionated RT revealed OS RR for ERT versus LRT of 1.44 (95% CI, 1.17 to 1.77; P = .001) and 1.39 (95% CI, 1.02 to 1.90; P = .04) at 2 and 3 years, respectively, indicating a survival benefit of ERT versus LRT. Studies using once-daily fractionation showed no difference in 2- and 3-year OS RRs for ERT compared with LRT. Studies using platinum-based chemotherapy had OS RRs of 1.30 (95% CI, 1.10 to 1.53; P = .002) and 1.35 (95% CI, 1.07 to 1.70; P = .01) at 2 and 3 years, respectively, favoring ERT. Studies using nonplatinum-based chemotherapy regimens had nonsignificant differences in OS. Conclusion A small but significant improvement in 2-year OS for ERT versus LRT in LS-SCLC was observed, similar to the benefit of adding RT to chemotherapy or prophylactic cranial irradiation. A greater difference was evident for hyperfractionated RT and platinum-based chemotherapy.

Purpose: To determine the impact of continued smoking by patients receiving chemotherapy (CHT) and radiotherapy (RT) for limited-stage small-cell lung cancer (LSCLC) on toxicity and survival. Patients and Methods: A retrospective review was carried out on 215 patients with LSCLC treated between 1989 and 1999. Treatment consisted of six cycles of alternating cyclophosphamide, doxorubicin, vincristine and etoposide, cisplatin (EP). Thoracic RT was concurrent with EP (cycle 2 or 3) only. Patients were known smokers, with their smoking status recorded at the start of chemoradiotherapy (CHT/RT). RT interruption during concurrent CHT/RT was used as the marker for treatment toxicity. Results: Of 215 patients, smoking status was recorded for 186 patients (86.5%), with 79 (42%) continuing to smoke and 107 (58%) abstaining during CHT/RT. RT interruptions were recorded in 38 patients (20.5%), with a median duration of 5 days (range, 1 to 18 days). Median survival for former smokers was greater than for continuing smokers (18 v 13.6 months), with 5-year actuarial overall survival of 8.9% versus 4%, respectively (log-rank P = .0017). Proportion of noncancer deaths was comparable between the two cohorts. Continuing smokers did not have a greater incidence of toxicity-related treatment breaks (P = .49), but those who continued to smoke and also experienced a treatment break had the poorest overall survival (median, 13.4 months; log-rank P = .0014). Conclusion: LSCLC patients who continue to smoke during CHT/RT have poorer survival rates than those who do not. Smoking did not have an impact on the rate of treatment interruptions attributed to toxicity.

AbstractBackgroundConsolidation radiotherapy (cRT) in extended disease small cell lung cancer (ED-SCLC) showed improved 2-year overall survival in patients who responded to chemotherapy (ChT) in CREST trial, however results of two meta - analysis were contradictive. Recently, immunotherapy was introduced to the treatment of ED-SCLC, making the role of cRT even more unclear. The aim of our study was to access if consolidation thoracic irradiation improves survival of ED-SCLC patients treated in a routine clinical practice and to study the impact of cRT dose on survival. We also discuss the future role of cRT in the era of immunotherapy.Patients and methodsWe retrospectively reviewed 704 consecutive medical records of patients with small cell lung cancer treated at the Institute of Oncology Ljubljana from January 2010 to December 2014 with median follow up of 65 months. We analyzed median overall survival (mOS) of patients with ED-SCLC treated with ChT only and those treated with ChT and cRT. We also compared mOS of patients treated with different consolidation doses and performed univariate and multivariate analysis of prognostic factors.ResultsOut of 412 patients with ED-SCLC, ChT with cRT was delivered to 74 patients and ChT only to 113 patients. Patients with cRT had significantly longer mOS compared to patients with ChT only, 11.1 months (CI 10.1–12.0) vs. 7.6 months (CI 6.9–8.5, p < 0.001) and longer 1-year OS (44% vs. 23%, p = 0.0025), while the difference in 2-year OS was not significantly different (10% vs. 5%, p = 0.19). The cRT dose was not uniform. Higher dose with 45 Gy (in 18 fractions) resulted in better mOS compared to lower doses 30–36 Gy (in 10–12 fractions), 17.2 months vs. 10.3 months (p = 0.03) and statistically significant difference was also seen for 1-year OS (68% vs. 30%, p = 0.01) but non significant for 2-year OS (18% vs. 5%, p = 0.11).ConclusionsConsolidation RT improved mOS and 1-year OS in ED-SCLC as compared to ChT alone. Higher dose of cRT resulted in better mOS and 1-year OS compared to lower dose. Consolidation RT, higher number of ChT cycles and prophylactic cranial irradiation (PCI) were independent prognostic factors for better survival in our analysis. For patients who received cRT, only higher doses and PCI had impact on survival regardless of number of ChT cycles received. Role of cRT in the era of immunotherapy is unknown and should be exploited in further trials.
