[Evaluation of quality of life in patients with advanced colorectal cancer treated with topotecan].
UNLABELLED: During last years a few new directions appeared in therapy of advanced colorectal cancer. Topotecan, a camptothecin analog, seems to be one of the promising novel drug in these cases. Its unique mechanism of action is connected with inhibition of the nuclear enzyme topoizomerase I. Assessing therapeutic effects of new cytotoxic drugs we should consider their impact on survival time and quality of life as well. The aim of our study was the attempt to assess the quality of life of patients with advanced colorectal cancer (IV stage in TNM scale), treated by topotecan. Clinical trial was performed in the group of 10 patients. Topotecan was administered intravenously at 1.5 mg/m2/day for 5 days and repeated every 21 days. Quality of life assessment was performed at special time points using Rotterdam Symptom Checklist. We observed improvement in quality of life in six out ten patients having advanced colorectal cancer. Two patients did not show any change in quality of life and two patients with progression of disease demonstrated lower quality of life during topotecan treatment. CONCLUSION: Topotecan has a positive influence on quality of life of patients with advanced colorectal cancer. Further study are needed to confirm this observation.
