P1.04-35 - Quick Progression (QP) in Patients Treated by Nivolumab (IO) in 2nd Line or More for Non-Small Cell Lung Cancer: ERORECI Study (GFPC 2016-04) (ID 11936)
16:45 - 18:00 | Author(s): Nicolas Paleiron
- Abstract
Background
Nivolumab has been approved in 2nd line for advanced non-small cell lung cancer (NSCLC). However, more than half of the patients had progressive disease at 16 weeks, without any response and sometimes with deleterious progressions. This descriptive prospective study aimed to assess the characteristics of non responders with QP after IO and the following treatments.
a9ded1e5ce5d75814730bb4caaf49419 Method
From September 1st, 2016 to August 31th, 2017, patients (pts) treated by IO (second line or more) with QP<16 weeks were included by 20 GFPC centers. NSCLC characteristics at the diagnosis, at the IO initiation, treatments (before IO, IO and after IO) and outcomes responses, progression free survival (PFS) according to lines of treatments were recorded.
4c3880bb027f159e801041b1021e88e8 Result
The sample included 319 pts: 64,3y± 9,6, smokers/ex-smokers: 48.0%-42.9%, male: 70.8%, PS01/2: 92.8%-7.2%, stage IV at diagnosis: 71.8%; adenocarcinoma: 63.9%. K-Ras mutated: 25.7%. Only 29% of patients had a PDL1 determination. 93% of pts received first line therapy, 32% second line, 10.3% third line before IO. First line PFS (PFS1) was 6.9m [6.43-7.8], PFS2: 9.33m [1.2-19], PFS3: 4.1m [1.56-12.43]. PFS for IO was 1.7m [0.76-4.16]. 229 (71,8%) patients had a IO PFS<2m; 14.7% of these patients stopped the treatment for toxicity. Among the 146 pts evaluable for response, PR was found in 23% of cases, SD in 30%, and PD in 47%.The table describe a comparison between two groups of QP during IO.

In real life, QP during IO remains a challenge in NSCLC. Multivariate analyses will be presented to characterize these patients.

P2.15-29 - Eligibility for Anti-Angiogenic Treatments in Patients with Squamous Non-Small Cell Lung Cancer (SQ-NSCLC): EPISQUAMAB Study (GFPC 2015-01) (ID 11338)
16:45 - 18:00 | Author(s): Nicolas Paleiron
- Abstract
Background
Antiangiogenic treatments are today restricted to non-squamous NSCLC. New drugs, like ramucirumab, have been approved in second line setting for advanced NSCLC regardless histology but there is little information about the rate of squamous NSLC eligible to these treatments. This descriptive, prospective, observational study aimed to assess the rate of squamous advanced NSCLC patients eligible to anti-angiogenic treatments.
a9ded1e5ce5d75814730bb4caaf49419 Method
Each participating center had to include consecutive relapsed advanced SQ-NSCLC and to assess the presence of common criteria which restricted the use of antiangiogenic treatments (hemoptysis, cardiovascular diseases, tumoral extension to blood vessels and tumoral cavitation).
4c3880bb027f159e801041b1021e88e8 Result
From july 2016 to july 2017, 317 patients were included: 256 (80.8%) men, PS0/1/2 in 30.5%/54.5%/14.9% patients, stage IV in 74.5% of cases. Ineligibility criteria for anti-angiogenic therapy were found in 53.6% of patients (one single criteria in 29,3%, two criteria in 19,9%, three in 3.5%). The main reasons for ineligibility was as followed: blood vessel extension 39.8%, cavitation 20.5%, hemoptysis 7.2%, cardiovascular diseases 12.1%.
Table described patients characteristics according to the ineligibility criteria: Cavitation had the highest number of metastatic disease, cardiovascular diseases the highest number of men and number of metastatic site.
In a non-selected advanced SQ-NSCLC population, only half of these patients are ineligible to a second line anti-angiogenic treatments with a wide majority of tumoral blood vessel extensions and cavitations.
