Abstract 4840


Using Tumor Growth Rate (TGR), we previously described HPD in 10% of 89 NSCLC pts treated with IO in a single institution. In this retrospective study, we explored HPD in a larger and multicenter cohort of advanced NSCLC pts treated with IO.


We performed a clinical and radiological retrospective analysis of consecutive NSCLC pts, treated with IO, in 5 different institutions, between November 2012 and March 2017. Eligibility criteria required, for each patient, 3 CT scans performed before IO, at baseline and during IO respectively, centrally reviewed by a senior radiologist and assessed according to RECIST 1.1 criteria. We calculated TGR at baseline of IO (baseline CT scan (n) vs (n-1) CT scan), TGR during IO (n + 1 CT scan vs baseline) and the variation per month of TGR between both (delta TGR). Pts were defined HPD if the absolute delta TGR increased by at least 50%. Median overall survival (mOS) and median progression free survival (mPFS) were estimated using the Kaplan-Meier method and compared between HPD and not HPD using the log-rank test.


242 pts were eligible. 64% were male, 50% ≥65 years, 51% smokers, 10% PS ≥ 2, 63% adenocarcinoma. 19% of NSCLC had KRAS mutation, 2% EGFR mutation, 2% ALK rearrangement, 35% had unknown molecular status. PD-L1 expression was positive in 12% of pts, negative in 11% and unknown in 77%, more than 90% of pts received single agent PD1-inhibitor in ≥ 2 line. Response rate (RR) to IO, mPFS and mOS were respectively 15%, 3.9 months (m) [3; 5], 13.4m [9; 42], median follow up was 10m [8; 12]. Compared to baseline, TGR decreased during IO (delta TGR ≤0) in 64% of pts, increased (delta TGR>0) in 36% (not regressing tumors). 40 pts (16%) had HPD. Only 3 pts (1,2%) had confirmed pseudoprogression, 2 of them were initially qualified as HPD. Tumor burden baseline, clinical, molecular, pathological characteristics, PD-L1 status and RR to treatment before IO were not different between HPD and not-HPD pts. Compared to not-HPD population, HPD pts had significantly lower mPFS (1.4 vs 4.9m, p 


HPD occurs in 16% of 242 advanced NSCLC pts treated with IO, leading to decreased survival. Further work is needed to better characterize this population.
