Abstract

In order to evaluate the clinical efficacy and the safety profile of molecularly targeted therapies as a palliative approach in elderly populations affected by advanced thoracic neoplasms, we retrospectively studied, in terms of effectiveness and toxicities, a group of pretreated elderly metastatic non-small cell lung cancer (NSCLC) patients admitted to our institution and treated with erlotinib at standard daily/dose. Forty-three patients aged 70 years or older who had previously failed on chemotherapy or radiotherapy were treated with oral Eerlotinib (150 mg/d) until disease progression or unacceptable toxicity. Clinical data, pathological types, potential prognostic factors, efficacy and toxicity of erlotinib were included in this analysis. In our series we observed: objective responses in six patients (14%) and stable disease in 15 (35%). Skin rash was the most common side effect (67%). Grade 3-4 adverse events were observed in 16 cases (37%). The median overall survival and the median progression-free survival were 8.4 months (CI 95%: 0.7-43.6) and 3 months (CI 95%: 0.4-28.4), respectively. Patients with adenocarcinoma achieved the best disease control rate (p=0.027), while not/former smokers showed a better response (p=0.069). In our experience the use of erlotinib after chemotherapy failure in an unselected elderly population affected by NSCLC showed moderate efficacy and a moderate safety profile. However, erlotinib represents a valid option in this setting, but other factors such as biological information, comorbidities and concomitant medications need to be carefully take into consideration in this particular subset of cancer patients.
