Objective: We previously reported the feasibility of short-term low-volume hydration in patients with advanced lung cancer who received cisplatin-based chemotherapy (Jpn J Clin Oncol 2013). We sought to determine the clinical usefulness of a more convenient hydration method, evaluating the safety and efficacy of shorter-term and lower-volume hydration. Method: Chemonaïve patients with advanced lung cancer who were ≤75 years and reserved an adequate renal function for cisplatin use (≥60 mg/m2) were eligible. An intravenously administered hydration of 1700 ml in ~3.5 h with 1500 ml of orally administered hydration was investigated. The primary endpoint was the proportion of patients without grade 2 or worse renal toxicity in the first cycle. Results: A total of 45 patients were registered, all of whom were evaluable for renal toxicity. The median baseline creatinine score was 0.70 mg/dl, and the median cisplatin dose on day 1 was 75 mg/m2. In the first cycle, one patient (2 %) developed grade 2 creatinine toxicity, and thus, the proportion of patients with less than grade 2 was 98 % (the lower limit of 95 % confidence interval; 93 %), which met the primary endpoint. Five patients (11 %) had grade 1 or greater nephrotoxicity, three of whom successfully recovered. The objective response rate was 24 % and median progression-free survival 5.8 months. Conclusion: This prospective study demonstrated the safety and efficacy of shorter-term lower-volume hydration.
