Combination of low-dose cisplatin and gemcitabine for treatment of elderly patients with advanced non-small-cell lung cancer.
OBJECTIVE
To evaluate the feasibility, toxicity and efficacy of the combination of low-dose cisplatin (CDDP) and gemcitabine (GEM) in elderly patients with advanced non-small-cell lung cancer (NSCLC).


METHODS
This phase II trial included 46 patients aged 70 years or older with previously untreated advanced NSCLC. All patients were evaluable for response and toxicity. Treatment consisted of CDDP 50 mg/m(2) on day 1 plus GEM 1000 mg/m(2) on days 1 and 8. The regimen was repeated every 21 days. Patients received a minimum of three courses unless progressive disease was detected.


RESULTS
A total of 190 GEM-CDDP courses were administered (median 4.1 courses per patient). The chemotherapy regimen was well tolerated. No patients developed grade 4 toxicity. Grade 3 toxicities were as follows: neutropenia in six patients (13%), and anemia, thrombopenia and nausea/vomiting in one (2%) each. Two patients (4%) had mild nephrotoxicity. Of the 46 patients, 16 had a partial response (35%, 95% confidence interval, CI, 28-52%), 17 (37%) remained stable and 13 (28%) had disease progression. Eastern Cooperative Oncology Group performance status improved in 17 patients (37%), whereas 25 (54%, 95% CI 44-74%) showed a clinical benefit. Median time to progression was 20 weeks. Overall median survival was 44 weeks, with a 1-year actuarial survival rate of 35%.


CONCLUSIONS
The combination of low-dose CDDP and GEM for elderly patients with advanced NSCLC is an effective and well-tolerated chemotherapeutic approach.
