Abstract

Purpose

To compare the overall survival (OS) of patients with advanced non–small-cell lung cancer (NSCLC) treated with docetaxel plus cisplatin (DC) or docetaxel (D) alone.

Patients and Methods

Chemotherapy-naïve patients with advanced/metastatic NSCLC were randomly assigned to receive either DC (n = 167; docetaxel 100 mg/m2 on day 1, cisplatin 80 mg/m2 on day 2, and recombinant human granulocyte colony-stimulating factor (rhG-CSF) 150 μg/m2/d on days 3 to 9) or D (n = 152; 100 mg/m2 on day 1 without rhG-CSF) every 3 weeks.

Results

The overall response rates were 36.5% for DC (three complete responses and 58 partial responses) and 21.7% for D (one complete response and 32 partial responses; P = .004). The median OS was 10.5 months (range, 0.5 to 41 months) and 8.0 months (range, 0.5 to 41 months) for DC and D, respectively (P = .200). The 1- and 2-year survival rates were 44% and 19% for DC and 43% and 15% for D, respectively. Median times to tumor progression were 4.0 and 2.5 months for DC and D, respectively (P = .580). Grade 2/3 anemia was significantly higher with DC than with D (33% v 16%; P = .0001). Fifteen (9%) DC and 12 (8%) D patients developed febrile neutropenia. Grade 3/4 nausea/vomiting (P = .0001), diarrhea (P = .007), neurotoxicity (P = .017), and nephroroxicity (P = .006) were significantly more common with DC than with D. There were five treatment-related deaths in the DC group and one in the D (P = .098).

Conclusion

DC regimen resulted in a higher response rate but without improvement in median time to tumor progession or OS compared with D. D could be a reasonable front-line chemotherapy for patients who cannot tolerate cisplatin.
