Clinical observation of icotinib hydrochloride for patients with advanced non-small cell lung cancer / 中华肿瘤杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore the efficacy and side effects of icotinib hydrochloride in the treatment of patients with advanced non-small cell lung cancer (NSCLC).</p><p><b>METHODS</b>The efficacy and side effects of icotinib hydrochloride in treatment of 59 cases with stage IV NSCIC and followed-up from March 2009 to January 2012 were retrospectively analyzed.</p><p><b>RESULTS</b>Twenty seven patients (45.8%) showed partial response (PR), 17 patients (28.8%) achieved SD, and 15 (25.4%) had progressive disease. The objective response rate (ORR) was 45.8% (27/59), and disease control rate (DCR) was 74.6% (44/59). Among the 23 patients with EGFR mutation, ORR was 73.9% (17/23), and DCR was 95.7% (22/23). Thirty six patients (61.0%) achieved remission of symptoms to varying degrees. The main symptoms relieved were cough, asthmatic suffocating, pain and hoarseness. The major adverse events were mild skin rash (35.6%) and diarrhea (15.3%). Others were dry skin, nausea and stomach problems. The efficacy of icotinib hydrochloride were related to the ECOG performance status, smoking history, EGFR mutation and rash significantly (P < 0.05).</p><p><b>CONCLUSIONS</b>Monotherapy with icotinib hydrochloride is effective and tolerable for patients with advanced NSCLC, especially with EGFR mutation.</p>
