Pa. Kosmidis et al., PACLITAXEL AND CARBOPLATIN IN INOPERABLE NON-SMALL-CELL LUNG-CANCER -A PHASE-II STUDY, Annals of oncology, 8(7), 1997, pp. 697-699
Background: Based on the high activity of single-agent paclitaxel and
the superior one-year survival rates of patients with non-small-cell l
ung cancer (NSCLC) treated with carboplatin, a phase II trial was init
iated using both agents in patients with inoperable stages III and IV
disease to investigate the efficacy and toxicity of the combination. P
atients and methods: Since July 1995, 60 patients fulfilling all eligi
bility criteria entered this study. All patients received paclitaxel 1
75 mg/m(2) as a three-hour infusion, and carboplatin dosed to an area
under the concentration-time curve of seven, every three weeks. No gra
nulocyte colony-stimulating factor was given. Of the 56 male and four
female patients, the median age was 57 years (range 29 to 75 years) an
d the median Eastern Go-Operative Oncology Group performance status wa
s one. Most of the patients had stage IV (34) adenocarcinoma (31) with
low differentiation (28). The median number of chemotherapy cycles wa
s three, with a range of one to eight. Results: Of 55 evaluable patien
ts, 15 (27.3%) achieved partial responses, 15 (27.3%) had stable disea
se, and 25 (45.4%) had progressive disease. The median survival was 8.
95 months and 21.6% of the patients survived more than one year. Grade
2/3 nonhematologic toxicity included alopecia (59%), neurotoxicity (3
%), and myalgia/arthralgia (10%). Grade 213 neutropenia occurred in 14
% of patients, whereas grade 3/4 thrombocytopenia was seen in only 4%.
One patient died of complications of a severe allergic reaction. Conc
lusion: Combination treatment using paclitaxel and carboplatin is acti
ve and well tolerated in patients with inoperable non-small-cell lung
cancer. The dose-response relationship to paclitaxel and results of co
mparison with other platinum-based regimens remain to be determined.
