MINI17.04 - Erlotinib in 2nd Line in Advanced Squamous NSCLC: Final Results of the Pepita Cohort (ID 822)
17:05 - 17:10 | Author(s): P.J. Souquet
- Abstract
Background:
Erlotinib in 2[nd] line improves survival in patients with recurrent/progressive NSCLC, is also active in squamous cell NSCLC, as reported in a BR.21 study subgroup. So far, no prospective non interventional study has specifically evaluated patients with this histological subtype treated with erlotinib. We present the final results of PEPITA cohort.
Methods:
PEPITA is a French multicenter, prospective cohort study assessing erlotinib modalities of use in daily practice in squamous NSCLC. The primary endpoint was progression-free survival (PFS); secondary endpoints included patients’ characteristics, overall survival (OS), safety and quality of life. EGFR mutation was tested in 41 patients (28.5%) reason why exploratory analyses assessing EGFR genotyping and smoking status were also performed.
Results:
Between June 2012 - May 2013, 152 patients were included and 146 patients were analyzed for efficacy; median follow-up was 5.31 months (0.03-17.65).

Conclusion:
PEPITA is the first non-interventional study assessing modalities of use in daily practice of patients with stade IIIb/IV squamous NSCLC treated in 2[nd] line with erlotinib. This final analysis show similar efficacy and safety results to those observed in clinical trials. Clinical profile may drive EGFR genotyping.

MINI30.07 - Crizotinib in Patients with ROS1 NSCLC. Preliminary Results of the AcSé Trial (ID 2426)
19:05 - 19:10 | Author(s): P.J. Souquet
- Abstract
- Presentation
Background:
To avoid uncontrolled off-label use and allow for a nationwide safe access to crizotinib (crz) for patients (pts) with an ALK, MET or ROS1 positive (+) tumor, the French National Cancer Institute (INCa) launched the AcSé program, funding both access to tumor molecular diagnosis and an exploratory multi-tumor 2-stage design phase II trial. We report the preliminary results of the ROS1+ NSCLC cohort.
Methods:
ROS1 status was assessed in 28 regional INCa molecular genetic centers by break-apart FISH assays in tumor samples showing an IHC score of ≥1+. Pts with ROS1 rearrangements, progressing after at least one standard treatment (including a platinum-based doublet, unless pts were considered as unfit for chemotherapy) were proposed to receive crz 250 mg BID. Responses were centrally assessed using RECIST v1.1. The objective response rate (ORR) and disease control rate (DCR) were assessed every 8 weeks.
Results:
From Aug. 5, 2013 to Mar. 1, 2015, 39 pts with ROS1+ NSCLC were enrolled. 37 pts had received crz, leading to 37 pts with clinical information. Median age: 62 years (range 33–81), 70% females, 95% non-squamous histology, and 94% metastatic disease at study entry. Median number of prior treatments: 2 (range 1 –7). Twenty four pts were still on treatment at the cut-off date, 13 have stopped crz (8 PD, 3 adverse events (AEs), 2 deaths). Among the 27 pts evaluable for response at 8 weeks, we observed 16 PR, 7 SD and 4 PD, leading to ORR=59% [95% CI:39-78], and DCR=85% [66-96]. DCR at 6 months was 57% (disease control was achieved in 12/21 evaluable pts). Crz was well tolerated with only 4 grade ≥3 (1 AE + 3 SAEs) and 9 grade 1-2 SAEs. Most common AEs, mainly grade 1, were visual disorders (54% of pts), peripheral edema (51%), diarrhea (48%), nausea (46%), and elevated transaminases (43%).
Conclusion:
Crz was well tolerated and achieved a robust treatment response rate in ROS1+ NSCLC. These results underline the interest of integrating ROS1 in biomarkers routine screening. Survival data and duration of response will be presented.

ORAL03.06 - Activity of Crizotinib in MET Amplified NSCLC: Preliminary Results of the AcSé Trial (ID 1200)
11:39 - 11:50 | Author(s): P.J. Souquet
- Abstract
- Presentation
Background:
Crizotinib (crz) is registered only for the treatment of patients (pts) with ALK-translocated lung cancer. Crz is also a MET inhibitor. MET is amplified in several malignancies. Activity of crz in MET amplified (+) tumors was explored as part of the French National Cancer Institute (INCa) AcSé program, including both access to tumor molecular diagnosis and an exploratory multi-tumor 2-stage design phase II trial. We report here results in pts with MET + NSCLC.
Methods:
MET analysis on formalin-fixed, paraffin-embedded tumor samples was proposed in 170 investigating centers and performed in 28 regional INCa molecular genetic centers. MET+ was explored by FISH in tumor samples showing an IHC score of ≥2+. Pts with a tumor showing > 6 MET copies, whatever the MET/CEN7 ratio, were eligible, providing they were not eligible for any other academic or industry trial evaluating another MET inhibitor. Study treatment consisted in crz 250 mg BID. The objective response rate (ORR) and disease control rate (DCR) were assessed every 8 weeks, using RECIST v1.1.
Results:
From Aug. 5, 2013 to Mar. 1, 2015, 25 pts with MET+ NSCLC were enrolled and received crz. Median age was 59 years (range 30–92). Forty-four percent were females, 92% had tumors of non-squamous histology, and 96% presented with metastatic disease at study entry. Median number of prior treatments was 2 (range 0 – 11). Eight pts were still on treatment at the cut-off date, 17 have stopped crz (15 progressive diseases (PD), 1 adverse event (AE), 1 patient’s choice). Among the 18 pts evaluable for response after 8 weeks, we observed 7 partial responses, 6 stable diseases and 5 PD, leading to an ORR of 39% [95% CI:17-64], and a DCR of72% [47-90]. DCR at 6 months was 22% (4 pts out of the 18 evaluable pts). Crz was well tolerated with only 5 grade ≥3 (2 AE + 3 SAEs) and 3 grade 1-2 SAEs. Most common AEs, mainly grade 1 or 2, were nausea (60% of pts), visual disorders (52%), anemia (52%), elevated transaminases (48%) and vomiting (40%).
Conclusion:
Nationwide biomarker-driven access to crz for pts with MET+ malignancy is feasible. Crz was well tolerated and showed responses in pretreated MET+ lung cancers. Survival data and duration of response will be presented.

ORAL27.06 - Disparities in Lung Cancer Incidence and Management Care in France: A Nationwide Cohort Study (the TERRITOIRE Study) (ID 1177)
11:39 - 11:50 | Author(s): P.J. Souquet
- Abstract
- Presentation
Background:
Reducing health inequalities in oncology is a major public health priority in France, particularly in terms of social and geographic exclusion and equity of access to health care services. However, no specific registry currently exists for patients with lung cancer allowing description and comparison of local situations. Our aim was to use available National medico-administrative databases to constitute a nationwide population-based cohort study to analyze disparities among French areas (the TERRITOIRE study).
Methods:
We included all patients who had a first diagnosis of lung cancer between January 1rst and December 31th 2011 in the National hospitals databases (PMSI, Programme de Médicalisation des Systèmes d'Information). Patients’ data were linked to create a retrospective cohort study with a two-year follow-up period. The 22 administrative regions were considered in this analysis. In addition of demographic characteristics, metastatic status, comorbidities and treatment procedures, we assigned each patient to socioeconomic deprivation and urbanization scores based on their postcode of residence.
Results:
We identified 41,715 patients newly diagnosed for lung cancer. Mean age at diagnosis was 66.4(±11.9) years and most of patients were men (71.8%). Patients from socioeconomic deprived areas represented 27.5% of the whole lung cancer population, ranging from 9.6% to 55.2% according to the region. Incidences of lung cancer were 35.1 per 100,000 in women and 95.3 per 100,000 in men. Age-standardized incidences showed important disparities between French regions ranging from 27.5 to 55.0 and from 82.4 to 118.2 per 100,000 in women and men, respectively. Higher incidences were found in the northern and eastern regions for men and in the southern and eastern regions for women. Although patients living in rural areas were the larger group (34.5%), Age-standardized incidence significantly increased with urbanization: from 61.8 per 100.000 in rural areas to 73.9 per 100.000 in urban areas. A majority of patients was diagnosed at a metastatic stage (52.7%) and regional disparities were important ranging from 45.0% to 58.1%. This rate also appeared higher in patients diagnosed in public hospitals compared to private ones (56.1% vs 42.9%, p<0.0001) and in local hospitals compared to university ones (60.2% vs 49.6%, p<0.0001). Adjusted comparisons showed significantly higher incidences of stage IV patients at the time of diagnosis in five regions for men and two regions for women. A majority of patients (N=23,842; 57.2%) died in the hospital during the 2-year follow-up, including 15,642 patients (71.2%) having metastasis at the time diagnosis.
Conclusion:
We have demonstrated that a comprehensive population-based cohort using medico-administrative data is a suitable approach to illustrate disparities in lung cancer incidence, management care and outcomes in France. Data from this study should help local clinical teams and health stakeholders to better understand inequality issues in their areas.

P2.04-039 - A World of EGFR Screening Test (ID 2406)
09:30 - 09:30 | Author(s): P.J. Souquet
- Abstract
Background:
EGFR mutation status has emerged as a crucial issue in the management of lung cancer. In France, the national cancer institute has launched a network of EGFR screening test facilities for daily practice. There is however very little information about EGFR screening test and TKI drugs availability in routine at a worldwide level. We also hypothesized that inequalities might occur in the EGFR test availability regarding country development. Thus, the aim of this study was to edit a map of routine EGFR test and drugs availability and cost subsequently associated to development indicators.
Methods:
We conducted a prospective expert opinion survey. An electronic questionnaire, edited in French or English, was addressed to experts in thoracic oncology in each country of the world. Experts were selected by three different ways: (i) email lists of partner institutions (the European Respiratory Society, the Asian Pacific Society of Respiratory, the Asociacion Latinoamericana del Torax, the Thoracic society of Australia and New Zealand), (ii) manual research on the internet, and (iii) the IASLC member. Interpretation of multiple answers was performed according to an a priori determined algorithm. Questionnaire contained 10 multiple-choice questions on availability, and cost of EGFR screening test and EGFR tyrosine kinases inhibitors (TKI). Country development was estimated by the human development index (HDI) provided by UN development program.
Results:
We obtained answer from 74 countries, covering 78% of world population according to UN data. Experts (n=100) were mainly clinicians and worked in hospitals or cancer centers. Non-responding countries were mainly from Africa and Asia, and had a significantly lower HDI than responding countries. EGFR screening test was routinely available in whole the country or only in some region for 57 countries (70% of the world population; figure 1). The remaining-cost of the test was less than 500 US$ in 49 countries (42.5% of the population). Availability and cost of the test were both significantly linked to HDI. The delay to obtain test result was less than 30 working-days in 71% of the population. Erlotinib, Gefitinib, Afatinib and Icotinib were routinely available in 75%, 66%, 31% and 23% of the world population respectively. Availability and cost of erlotinib, gefitinib and afatinib were also associated to HDI. Figure 1
Conclusion:
EGFR screening test and EGFR TKI are widely accessible in routine worldwide. However, there are large discrepancies in the access and the cost of this innovative process regarding development index.

P3.01-043 - Assessing Treatment Strategies for Lung Cancer in Octogenarians: Insights From a Cohort of 337 Patients (ID 1216)
09:30 - 09:30 | Author(s): P.J. Souquet
- Abstract
Background:
Aging increases the incidence of lung cancer in octogenarians. In this population, only limited data about treatment strategies and results are available, as those patients are usually not eligible for clinical trials; meanwhile, previously reported cohorts mostly focused on early-stage tumors. Our objective was then to provide a global picture of the treatment strategies for lung cancer in octogenerians, and to parallel those with available standards.
Methods:
Retrospective observational study of all consecutive patients aged 80 or more, with pathologically-confirmed lung cancer, and diagnosed at the Hospices Civils de Lyon between January 2005 and April 2014.
Results:
337 patients were included, 298 (88%) with non-small cell lung cancer (NSCLC), and 39 (12%) with small-cell lung cancer. For NSCLC, tumor was stage I, II, III, and IV in 10%, 9%, 25% et 57% of cases, respectively. Overall survival was 8.4 months. Geriatric assessment had been done only for 11% of patients. Overall, a standard treatment strategy - i.e. based on available recommendations and guidelines - was conducted for 42% of patients, while 24% received non-standard treatment, and 34% best supportive care only. At multivariate analysis, favorable prognostic factors on overall survival were performance status 0-1 (p<0.001), stage I/II (p<0.001), adenocarcinoma histology (p=0.026), and a standard treatment strategy (p<0.001). In the setting of metastatic NSCLC, 35% of patients received chemotherapy, the most frequent regimen being carboplatine and paclitaxel.
Conclusion:
Octogenarians with lung cancer are eligible for antitumor treatment in nearly 70% of cases, consisting of standard, recommended therapy in about half of the cases. Our data provide a unique overview of the management of octogenarians with lung cancer, to foster future prospective studies dedicated to this subset of patients.
