[Gemcitabine-cisplatin combination in the first line treatment of non-small cell lung cancer. Our experience and analysis of safety].

In our Department we have studied the first line treatment of 90 stage IIIA-IV non-small cell lung cancer patients using gemcitabine/cisplatin combination. Thirteen cases have been unevaluable for various reasons. At the time of evaluation the planned 4 cycles have been delivered to 38% of patients (34/90). The PR was 39% (30/77), the CR was 2.6% (2/77) while the ORR was found to be 41% (32/77). 226 treatment cycles have been evaluated for side effects. There was no treatment-induced death in this series. CTC grade 3-4 neutropenia occurred in 5.7% of the cycles and only in 2 cases combined with fever. CTC grade 3-4 thrombocytopenia occurred in 4.4% of the cycles but only one patient required platelet suspension administration. Grade 3-4 anaemia developed in 3.5% of the cycles where 5 cases have been treated with RBC concentrate while 3 cases with erythropoietin. Complete alopecia occurred in 6 patients but 3 of them received brain irradiation as well. CTC grade 3-4 nausea and vomiting occurred in 4.4 and 3% of the cycles, respectively, but rehydration was only necessary in 3% of the cycles. Delay of the therapy due to hematological toxicity or vomiting occurred in 8% of the cycles but did not last longer than 2 weeks. Severe CTC grade 3-4 nephrotoxicity did not occur in this study while grade 1-2 elevation of serum creatinine level was found in 1.7% of the cycles. We have concluded that the gemcitabine/cisplatin combination is a safe outpatient modality for the first line treatment of advanced non-small cell lung cancer patients.
