Abstract |
Erlotinib is an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor, which is an effective treatment for patients with non-small cell lung cancer (NSCLC), especially those harboring activating EGFR mutations. A previous phase III trial suggested that patients with EGFR wild-type (EGFR-wt) NSCLC or elderly patients with disease progression after cytotoxic chemotherapy might benefit from erlotinib monotherapy. However, few studies have prospectively evaluated the efficacy and safety of second- or third-line erlotinib monotherapy for elderly patients with EGFR-wt advanced or recurrent NSCLC. Pretreated patients aged ≥70 years with EGFR-wt stage IIIB/IV NSCLC or those with postoperative recurrence were enrolled and received oral erlotinib at a dose of 150 mg/day until disease progression. Primary outcome was the objective response rate (ORR). Secondary end points included the disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and toxicity profile. This study was terminated early because of the results from a Japanese phase III trial (DELTA trial). Sixteen patients were enrolled between April 2010 and May 2013. The median age was 78 years (range 70-84 years). Six patients were female. Five patients had an Eastern Cooperative Oncology Group performance status of 0. Eleven (69%) patients had adenocarcinoma. Fifteen (94%) patients were treated with erlotinib as a second-line therapy. The ORR was 0% [95% confidence interval (CI) 0-17.1]. DCR was 56.3% (95% CI 33.2-76.9). The median PFS and OS were 1.7 months (95% CI 1.3-2.2) and 7.2 months (95% CI 5.6-8.7), respectively. The most commonly occurring adverse events included acneiform eruption (31.3%) and skin rash (25.0%). One patient developed grade 3 interstitial lung disease, which improved following steroid therapy. In pretreated elderly patients with advanced or recurrent EGFR-wt NSCLC, daily oral erlotinib was well tolerated; however, administration of the drug should not be considered as a second line therapy.
