Background: The objective of this study was to evaluate the possible effects of a paclitaxel containing chemotherapy on different neuropsychological parameters in women with ovarian cancer.
Materials and methods: Twenty-eight women with histologically documented epithelial ovarian carcinoma and treated with a combination chemotherapy consisting of paclitaxel and carboplatin entered the study. The patients were tested with a battery of different neuropsychological tests before, after 3 cycles and at the end of the chemotherapy.
Results: Twenty of the 28 patients responded to the chemotherapy (71%). Eleven patients (39%) developed peripheral neurotoxicity. The median values of 6 tests performed before the first chemotherapy cycle scored out of the normal range. These patients with deviant test results at the beginning of the paclitaxel/carboplatin infusions did not deteriorate during chemotherapy. We found a statistically significant improvement of the alphabetical cross out test from the first to the third measurement (mean increase = 4.07; 95% confidence interval = [0.99; 7.15]) (p < 0.05), indicating an improvement of the short-term attention, the concentration and the constancy of working during chemotherapy. The other tests failed to show statistically significant changes during chemotherapy (p > 0.05).
Conclusion: According to our results, a chemotherapy consisting of paclitaxel/carboplatin caused no signs of acute central nervous toxicity or neuropsychological deterioration.
