Abstract:
OBJECTIVE:To clarify the association between pre-treatment total bilirubin (PTB) level and severe toxicity in patients receiving cisplatin and irinotecan. METHODS:We analyzed retrospectively the relationships of grade 4 neutropenia or grade 3-4 diarrhea and clinical variables including PTB and pre-treatment neutrophil counts (PNC) using a logistic regression model. RESULTS:One hundred and twenty-seven patients (93 men, 34 women; median age: 61 years; range: 24-74 years) received cisplatin (60 or 80 mg/m2) on day 1 and irinotecan (60 mg/m2) on days 1 and 8 every 3 weeks or on days 1, 8 and 15 every 4 weeks. Grade 4 neutropenia occurred in 29 patients (23%) and grade 3-4 diarrhea occurred in 13 patients (10%). Grade 4 neutropenia was associated with a higher PTB level (odds ratio: 4.9; 95% confidence interval: 1.4-17.7), a higher cisplatin dose (2.8, 1.0-7.8) and a lower PNC (1.5, 1.0-2.3). Grade 3-4 diarrhea was associated with liver metastasis (11.2, 2.2-57.4), a higher cisplatin dose (5.0, 1.2-21.3) and a lower PNC (2.0, 1.1-3.6). CONCLUSIONS:PTB level was associated with the severity of neutropenia caused by cisplatin and irinotecan.
