A web-mediated follow-up algorithm based on self-reported symptoms improved OS due to early relapse detection and better performance status at relapse.
Introduction: A multicenter randomized clinical trial in France found an overall survival benefit of web-based patient-reported outcome (PRO)-based surveillance after initial treatment for lung cancer compared with conventional surveillance. The aim of this study was to assess the cost-effectiveness of this PRO-based surveillance in lung cancer patients.Methods: This medico-economic analysis used data from the clinical trial, augmented by abstracted chart data and costs of consultations, imaging, transportations, information technology, and treatments. Costs were calculated based on actual reimbursement rates in France, and health utilities were estimated based on scientific literature review. Willingness-to-pay thresholds of V30,000 per qualityadjusted life year (QALY) and V90,000 per QALY were used to define a very cost-effective and cost-effective strategy, respectively. Average annual costs of experimental and control surveillance approaches were calculated. The incremental cost-effectiveness ratio was expressed as cost per life-year gained and QALY gained, from the health insurance payer perspective. One-way and multivariate probabilistic sensitivity analyses were performed.Results: Average annual cost of surveillance follow-up was V362 lower per patient in the PRO arm (V941/year/patient) compared to control (V1,304/year/patient). The PRO approach presented an incremental cost-effectiveness ratio of V12,127 per life-year gained and V20,912 per QALY gained. The probabilities that the experimental strategy is very cost-effective and cost-effective were 97% and 100%, respectively.Conclusions: Surveillance of lung cancer patients using web-based PRO reduced the follow-up costs. Compared to conventional monitoring, this surveillance modality represents a cost-effective strategy and should be considered in cancer care delivery.
LBA9006 Background: We developed a web-application for an early detection of symptomatic relapse, complications and early supportive care in high-risk lung cancer patients between visits. A dynamical analysis of the weekly self-reported symptoms automatically triggered physician visit. Methods: We performed a national multi-institutional phase 3 prospective randomized study to compare web-application follow-up (experimental arm) for which patient’s self-scored symptoms that were weekly sent (between planned visits) to the oncologist and a clinical routine assessment with a CT-scan (every 3-6 months or at investigator’s discretion - standard arm). High risk lung cancer patients without progression and with a 0-2 performance status (PS) after an initial treatment were included. Maintenance chemotherapy or TKI therapy were allowed. In the experimental arm, an email alert was sent to the oncologist when some predefined clinical criteria were fulfilled: an imaging was then quickly prescribed. Early supportive cares were provided if adequate. The primary endpoint was to detect an improvement of 12% in 9 months survival in favor of the experimental arm (α = 5%, β = 20%, unilateral test). The boundary for declaring superiority with respect to overall survival at the pre-planned interim analysis was a p-value of less than 0.006. The PS at relapse, the quality of life (QOL) and cost-effectiveness were also investigated. Results: 121 patients were included in the intent-to-test survival analysis (90% were stage III/IV, median age: 65 y): 60 (61) in the experimental (standard) arms with equivalent baseline characteristics. Median follow-up was 9 months. Median overall survival in months was 19 (11.8), p=0.0014 (n = 121; HR = 0.33; 95 % CI, 0.16-0.67) and the PS at the first relapse was 0-1 for 81.5% (35.3%) of the patients (p<0.001) in the experimental (standard) arm. Conclusions: This trial shows a significant survival improvement using Web-application-guided follow-up that allowed better PS at relapse, earlier supportive care and reduction of routine imaging. QOL and cost analysis results will be presented during the meeting. Clinical trial information: NCT02361099.
Early assessment of TLG response by 18F-FDG PET/CT during concomitant radiochemotherapy of non-small cell lung cancer might be associated with survival.
