Objectives: It was the aim of this study to investigate gender differences in the outcomes of carboplatin and paclitaxel chemotherapy in patients with unresectable stage IIIB-IV non-small cell lung cancer (NSCLC). Methods: Gender, age, performance status, histology, hematological toxicity, tumor responses and survival parameters obtained retrospectively by medical chart review were analyzed. Results: A total of 227 patients (147 males and 80 females) were included. The median lowest leukocyte count was 2,900 (range 1,200-12,400)/mul in males and 2,200 (range 600-6,500)/mul in females (p < style="border-bottom: 1px dashed rgb(0, 102, 204); cursor: pointer;" class="yshortcuts" id="lw_1223403352_14">leukopenia was noted in 15% of male and in 39% of female patients (p < class="yshortcuts" id="lw_1223403352_15">response rate in evaluable patients was 39%. The median progression-free survival was 4.4 months for men and 5.3 months for women (p = 0.0081). After progression of the disease, gefitinib was administered in 64 (44%) male and 45 (56%) female patients, with a median treatment of 35 and 144 days, respectively. The median survival time was 11.9 months for men and 22.2 months for women (p < class="yshortcuts" id="lw_1223403352_16">response rates did not differ between the genders. Of note, hematological toxicity was more severe in female patients. Copyright © 2008 S. Karger AG, Basel.
