Second-line treatment of stage III/IV non-small-cell lung cancer (NSCLC) with pemetrexed in routine clinical practice: evaluation of performance status and health-related quality of life.

ABSTRACT: Second-line treatment of advanced non-small-cell lung cancer (NSCLC) improves overall survival. There is a lack of data regarding the impact on patients' overall health condition. This prospective, non-interventional study evaluated performance status (PS) and health-related quality of life (HR-QoL) during second-line pemetrexed treatment in routine clinical practice.Stage III/IV NSCLC patients who initiated second-line pemetrexed (standard vitamin and dexamethasone supplementation) were observed for a maximum of 9 treatment cycles. The primary objective was to evaluate the proportion of patients achieving improvement of Karnofsky Index (KI) of ? 10% (absolute) or maintaining KI ? 80% after the second treatment cycle ("KI benefit response"). HR-QoL was self-rated using the EuroQoL-5D questionnaire (EQ-5D). Factors potentially associated with KI benefit response were evaluated using logistic regression models.Of 521 eligible patients (73.5% Stage IV, median age 66.3 yrs, 36.1% ? 70 yrs, 62.0% with KI ? 80%), 471 (90.4%) completed at least 2 treatment cycles. 58.0% (95%CI 53.6%;62.2%) achieved KI benefit response after the second cycle. Patients with baseline KI ? 80%, no Grade 3/4 toxicities during the first 2 cycles, or combination regimen as prior first-line therapy were more likely to achieve a KI benefit response. EQ-5D scores improved over time. Grade 3/4 toxicities were reported in 23.8% of patients (mainly fatigue/asthenia 15.9%, neutropenia 8.7%).In this large prospective, non-interventional study of second-line pemetrexed treatment in patients with advanced NSCLC, including 36% elderly patients ( ? 70 years), physician-rated PS and self-rated HR-QoL were maintained or improved in the majority of patients.Registered on ClinicalTrials.gov (NCT00540241) on October 4, 2007.

Project description:IntroductionLittle data is available on patients with advanced non-squamous NSCLC treated with erlotinib specifically after failure of first-line pemetrexed-containing chemotherapy. We assessed the effectiveness, safety and tolerability of erlotinib in a real-world setting.MethodsProspective single-arm, open-label, multicenter, non-interventional study of erlotinib (150mg daily) in inoperable stage III/IV NSCLC after progression on first-line pemetrexed-containing chemotherapy without EGFR-mutation selection. Patients were followed according to routine practice and response assessment was performed using RECIST 1.1. The primary end point was progression-free survival (PFS). Secondary end points included best confirmed overall response rate (ORR), disease control rate (DCR), and overall survival (OS). Adverse events were recorded. An independent dataset was used to validate the results.ResultsIn all, 59 patients were screened, 57 enrolled, and 54 (36 men; median age 65 years) included in the per-protocol analysis. Median PFS was 1.8 (95% CI 1.4-2.6) months, with 11% (95% CI 5-21%) alive and progression-free at 6 months. The ORR was 0.0% (97.5% CI 0.0-6.8%) and the DCR 34.6% (95% CI 21.9-49.0%). Median overall survival was 5.8 (95% CI 3.3-8.6) months with 28% (95% CI 17-42%) alive at one year. Rash occurred in 60.7% (95% CI 46.7-73.5%), with severe rash in 12.5% (95% CI 5.1-24.1%). Any grade diarrhea was observed in 42.8% (95% CI 29.7-56.8%), with grade 3 occurring in 7.1% (95% CI 1.9-17.2%). Erlotinib was stopped in 21.0% (95% CI 11.3-33.9%) of patients due to adverse events, which were treatment related in 7%.ConclusionSecond-line erlotinib after pemetrexed treatment results in similar real-world outcomes as reported after non-pemetrexed containing first-line therapy. However, the overall duration of response in unselected patients remains limited and other effective treatments have in the meantime been introduced. No new safety signals were detected.

Project description:BackgroundData regarding real-life effectiveness of any treatment may improve clinical decision-making. The aim of this study was to evaluate real-life effectiveness of tyrosin-kinase inhibitors, bevacizumab and pemetrexed as first-line treatments in patients with advanced/metastatic non-small cell lung cancer (NSCLC).MethodsWe analyzed data of 2157 patients of the Czech TULUNG Registry of patients with advanced/metastatic NSCLC who received modern-era treatments between 2011 and 2018. Patients treated with gefitinib, erlotinib, afatinib, bevacizumab (+ maintenance), pemetrexed (+ maintenance) as first-line therapy were included in the study. A systematic literature search separately identified clinical trials suitable for calculation of comparator pooled OS and PFS for each regimen. For each subgroup, basic characteristics and survival data (Kaplan-Meier estimates) are shown. We propose the "index of real-life effectiveness" (IRE), a ratio of real-life OS/PFS and comparator pooled OS/PFS. Univariate and multivariate logistic regression identified factors were associated with longer OS (ie, IRE>1.1).ResultsSurvival analysis showed median OS of 23 months for erlotinib, 29.3 months for afatinib, 19.6 months for gefitinib, 12.2 months for pemetrexed, 17.5 months for pemetrexed maintenance, 15.8 months for bevacizumab and 15.8 months for bevacizumab maintenance. Calculated IREs for OS for the regimens were: erlotinib 1.013, afatinib 1.184, gefitinib 0.736, pemetrexed 1.188, pemetrexed maintenance 1.294, bevacizumab 1.178, and bevacizumab maintenance 1.189. Multivariate regression analysis showed that these factors were associated with longer OS: lower PS for afatinib; lower PS, absence of adverse events and female sex for bevacizumab; and lower PS and female sex for pemetrexed.ConclusionsThis study clearly demonstrated that real-life effectiveness of certain treatment regimens may strongly differ in various populations/health care systems, and comparison between TULUNG data and pooled survival data from trials showed higher real-life effectiveness for most of the studied first-line regimens. Lower ECOG PS, younger age, female sex and adverse events were associated with longer survival in most regimens.Key pointsSIGNIFICANT FINDINGS OF THE STUDY: Comparison between TULUNG data and pooled survival data from trials showed higher real-life effectiveness for most of the studied first-line regimens; for most regimens, lower ECOG PS, younger age, female sex and adverse events were associated with longer survival.What this study addsReal-life effectiveness of certain treatment regimens may strongly differ in various populations/health care systems.
