MA 18.14 - Non-Small Cell Lung Cancer (NSCLC) Treatment and Survival in Scandinavia: The SCAN-LEAF Study (ID 9295)
17:10 - 17:15 | Author(s): Oana Chirita

Background:
As the lung cancer treatment landscape evolves, it is important to understand changes in care and outcomes of patients with NSCLC. SCAN-LEAF objectives include describing NSCLC disease, treatments and health outcomes in Scandinavia (Denmark, Norway and Sweden). The present analyses examined treatment proportions and temporal trends in overall survival, drawing on national registry data.
Method:
NSCLC patients diagnosed 2005-2013 (follow-up until 2014) were included in the present analyses of this retrospective longitudinal cohort study. Patient characteristics and treatment described included demographics, disease stage at initial diagnosis [resectable: I-IIIA; locally advanced: IIIA-B (radiation therapy within 3 months); advanced: IIIB (no radiation therapy within 3 months)-IV], histology, non-drug treatment (surgery and radiation: present analyses include Norway and Sweden 2008-2014 only), and survival. Overall survival (OS) (%+95% CI) was calculated 1, 3, and 5 years post-diagnosis, by stage, and by diagnosis year.
Result:
66,012 NSCLC patients were diagnosed during 2005-2013 in Scandinavia (53.6% male, mean age 68.9 years); diagnosis stage: resectable (26%), locally advanced (15%), advanced (59%). In Norway and Sweden, surgery was performed on 58.5%, 9.9% and 1.9% of patients at resectable, locally advanced and advanced stage, respectively; radiation therapy in 28.0%, 58.0% and 30.4%, respectively. 1-yr OS gradually and significantly improved by calendar year of diagnosis for all disease stages. At 3 and 5 years post-diagnosis, OS was positively and significantly associated with calendar year of diagnosis for patients with resectable and locally advanced, but not advanced disease (Table 1).Table 1.

Conclusion:
These analyses showed modest improvements in survival for patients with earlier stage disease over time. However, the majority of patients were diagnosed with advanced stage disease for which no improvement in temporal trends of survival was found, beyond one year post-diagnosis. This suggests an unmet need for effective treatments still remains, particularly for patients with advanced disease.

OA 11.01 - Impact of Tobacco Smoking on the Humanistic and Financial Burden of Advanced Non-Small Cell Lung Cancer (A-NSCLC) (ID 8662)
11:00 - 11:10 | Presenting Author(s): Oana Chirita
- Abstract
- Presentation
Background:
Tobacco smoking has a negative impact on the prognosis of A-NSCLC. It is less well known how smoking impacts the burden of disease. As such, an analysis was conducted to evaluate the impact of a current tobacco smoking habit and/or history of smoking on the burden of A-NSCLC.
Method:
Data were collected between May 2015 and June 2016 from adult patients with Stage IIIB or IV NSCLC via medical chart reviews and patient self-completion forms as part of a multicentre, cross-sectional study conducted in France, Germany and Italy. Health status was measured using the EQ-5D-3L (including the visual analogue scale, EQ-VAS), quality of life (QoL) using the EORTC QLQ-C30 and work/activity impairment using the WPAI:GH questionnaire. Costs of NSCLC-related productivity losses and out-of-pocket expenses were also collected. Outcomes were stratified by smoking status (current/former smoker vs never smoked); no adjustments were made for possible confounding factors. Statistical significance was assessed using Mann–Whitney U tests.
Result:
1030 patients were recruited: mean patient age, 64.5 years; male, 65.9%; Stage IV NSCLC, 88.4%; non-squamous histology, 70.3%; receiving first-line therapy, 70.5%. Patients were largely receiving chemotherapy, regardless of line of therapy. In total, 1010 patients had smoking status recorded; 787 (77.9%) were current/former smokers and 223 (22.1%) had never smoked. Significant differences were observed between current/former smokers and patients who had never smoked for health status, QoL, work- and activity-related impairments, and NSCLC-related costs (TABLE). Figure 1
Conclusion:
A significant deterioration in health status and QoL, along with greater work- and activity-related impairments, was observed in current/former smokers with A-NSCLC. Moreover, costs of NSCLC-related productivity losses and out-of-pocket expenses were also higher versus those who had never smoked. These findings suggest an association between tobacco smoking and the humanistic and financial burden incurred by patients with A-NSCLC.

P1.06-012 - Non-Small Cell Lung Cancer (NSCLC) Patient Characteristics and Clinical Care Insights in Sweden: The SCAN-LEAF Study (ID 9537)
09:30 - 09:30 | Author(s): Oana Chirita
- Abstract
Background:
Understanding non-small cell lung cancer (NSCLC) epidemiology and outcomes is fundamental for clinical decision-making. SCAN-LEAF is a retrospective longitudinal cohort study that aims to describe NSCLC epidemiology, clinical care, and outcomes of patients in Scandinavia. The present analyses examine clinical characteristics and disease management of a subset of these patients.
Method:
Cohort 2 (EMR data from Uppsala, Stockholm sites, extracted using the Pygargus Customized Extraction Platform (CXP 3.0) and linked to registry data) consisted of NSCLC patients diagnosed 2005-2013 (follow-up until 2014). Co-morbidity burden was calculated with the Charlson Co-morbidity Index (CCI). Descriptive statistics were calculated, stratified by disease stage at diagnosis [resectable: I-IIIA; locally advanced: IIIA-B (radiation therapy within 3 months); advanced: IIIB (no radiation therapy within 3 months)-IV].
Result:
48.4% of the 3984 patients were male. At diagnosis, mean age was 68.4 years with disease stage distribution: resectable (30.4%), locally advanced (10.5%), advanced (56.3%), not specified (2.7%). CCI distribution was similar between stages, as was BMI. Smoking status: never (7.4%), former smoker (34.7%), current smoker (25.6%), unknown (32.4%). Histology: adenocarcinoma (63.3%), squamous (20.5%), NSCLC NOS (Not Otherwise Specified) (16.2%). ECOG: 0/1 (48.4%), 2/3 (13.2%), 4 (2.2%), unknown (36.2%). Metastases at diagnosis were reported for 42.4% patients. 829 patients were tested for molecular sub-type EGFR (of which 751 had a valid test result, of which 14.6% were positive for the mutation) and 267 for ALK (of which 247 had a valid test result, of which 14.6% were positive for the rearrangement). More patients with locally advanced disease were treated with radiation than patients with resectable or advanced disease [(68.8%, n=289) vs (35.9%, n=436) and (47.4%, n=1064), respectively], and a greater proportion of locally advanced patients received systemic therapy [(72.1%, n=303) vs (39.4%, n=478) and (67.1%, n=1505), respectively]. The proportion of patients not treated with surgery, radiation, or systemic therapy (based on pre-selected procedure lists) was higher for advanced (22.3%, n=500) vs resectable (6.5%, n=79) and locally advanced disease (11.9%, n=50).
Conclusion:
SCAN-LEAF EMR data provides unique insights into Scandinavian NSCLC patient populations and treatments. These data suggest unmet medical need based on majority of patients being diagnosed at advanced stage and low numbers tested for molecular subtype mutation but we expect these dynamics to change over time. Additionally, our data suggest unmet treatment need in patients with advanced disease based on a high proportion receiving no surgery, radiation, or systemic therapy, whilst acknowledging potential for misclassification and/or missing treatment data.

P2.01-012 - Impact of Brain Metastases on the Humanistic Burden Incurred by Patients with Advanced Non-small Cell Lung Cancer (A-nsclc) (ID 8179)
09:00 - 09:00 | Presenting Author(s): Oana Chirita
- Abstract
Background:
It is well documented that brain metastases negatively impact the prognosis for patients with A-NSCLC. However, it is less well known how secondary brain tumours impact health status, quality of life (QoL) and productivity in these patients. As such, an analysis of data from A-NSCLC patients was conducted to evaluate whether the metastatic site (brain vs non-brain) impacts the burden of disease.
Method:
Data were collected between May 2015 and June 2016 from adult patients with Stage IIIB or IV NSCLC via medical chart reviews and patient self-completion forms as part of a multicentre, cross-sectional study conducted in France, Germany and Italy. Health status was measured using the EQ-5D-3L (including the visual analogue scale, EQ-VAS), QoL using the EORTC QLQ-C30 and work/activity impairment using the WPAI:GH questionnaire. Outcomes were stratified by metastatic site (brain vs non-brain); no adjustments were made for possible confounding factors. Statistical significance was assessed using Mann–Whitney U tests.
Result:
1030 patients were recruited: mean patient age, 64.5 years; male, 65.9%; current/former smokers, 77.9%. Most patients had Stage IV NSCLC (88.4%), non-squamous histology (70.3%) and/or were receiving first-line therapy (70.5%). Patients were largely receiving chemotherapy, regardless of line of therapy. Of 910 evaluable Stage IV patients, 111 had brain metastases and 799 had non-brain metastases. Significant differences were observed between patients with brain metastases versus non-brain metastases for health status, QoL and activity-related impairments (TABLE). The percentage of work-related impairment was also numerically higher in patients with brain metastases. Figure 1
Conclusion:
Patients with A-NSCLC and secondary brain tumours had significantly worse health status and QoL, and experienced greater work- and activity-related impairments, compared with A-NSCLC patients with non-brain metastases. These findings may indicate a need for specific management/support programmes for patients with A-NSCLC and brain metastases.
