A phase II trial of erlotinib monotherapy for pretreated elderly patients with advanced EGFR wild-type non-small cell lung cancer.
Trial report in BMC research notes, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundErlotinib 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.
methodsPretreated 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.
resultsThis 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.
conclusionsIn 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.
