title: Bodyweight change during the first 5 days of chemotherapy as an indicator of cisplatin renal toxicity.
abstract: To determine whether bodyweight (BW) loss, daily urine volume (UV) or furosemide use are associated with cisplatin nephrotoxicity, performance status, serum chemistries before treatment, average daily UV, maximum BW loss and use of furosemide on days 1-5 of chemotherapy were evaluated retrospectively in chemotherapy-naive patients with thoracic malignancies who had received 80 mg/m(2) cisplatin. Associations between these parameters and the worst serum creatinine levels (group 1, grade 0-1; and group 2, grade 2-3) during the first cycle were evaluated. Of the 417 patients (327 men and 90 women; median age, 59 years), 390 were categorized into group 1 and 27 were categorized into group 2. More women and older patients were observed in group 2 than in group 1 (11.1 vs 5.2%, P = 0.044, and 65 vs 59 years, P = 0.041, respectively). The median average daily UV was 3902 mL in group 1 and 3600 mL in group 2 (P = 0.021). A maximum BW loss > or 2.1 kg was noted in 4.4% of patients in group 1 and 18.5% of patients in group 2 (P = 0.006). Furosemide was used in 206 (49.4%) patients. The median total dose of furosemide in groups 1 and 2 were 0 mg and 26 mg, respectively (P = 0.024). A multivariate analysis showed that a maximum BW loss > or = 2.1 kg and the total furosemide dose were significantly associated with group category. In conclusion, BW loss and total furosemide dose were associated with cisplatin nephrotoxicity.
