Elderly pts enrolled in trials are fit without cM but in clinical practice most suffer from cM. Methods: Medical records of 1221 pts diagnosed with NSCLC between 2008-2012 were screened. We examined pts of 75 yrs for demographics, clinical data and Tx details. Results: 233/1221 NSCLC pts received E at any line. 53/233 (23%) were 75 yrs old. Male:female ratio was 34:19, median age 79 yrs (range 75-88). NSCLC subtypes included 31 adenoca, 8 squamous, 9 NOS and 5 others. 50/53 pts had cM (≥2 in 46 pts, 1 in 4pt). Main cM were cardiovascular disease (n=41), COPD (n=14), other cancer (n=10) and diabetes (n=8). 8 pts were tested for EGFR mutations (5 -ve, 3 +ve). Performance Status was satisfactory (ECOG 0-1) in 8 pts and poor (2-3) in 45pts. 8pts were treated with E 100mg and 45 pts with E 150mg (12 pts needed dose reduction). Complete follow up data were found in 46pts. Mean duration of treatment was 79 days (range 9-662). 35/46 pts experienced side effects which led to treatment discontinuation in 12pts. Pts with abnormal creatinine clearance (n=13) were more likely to stop treatment due to s.e (6/13 versus 6/33). 17/46 pts (37%) achieved disease control (5 PR, 12 SD) and a time to progression (TTP) of 157 days while 22/46 pts had PD as best response (TTP 49d, range 19-88, CI 44,67-64,97). 7pts were not evaluable (stopped Tx due to s.e). All EGFR+ve pts had disease control (2PR, 1SD). Conclusions: E is a valuable option in elderly NSCLC patients with co-morbidities, especially if they harbor EGFR mutations. Impaired renal function might be associated with side effects and earlyTx discontinuation. ER -
