Routine administration of a single dose of cisplatin ≥ 75 mg/m2 after short hydration in an outpatient lung-cancer clinic.

Cisplatin is a pivotal drug in combined chemotherapy for non-small cell and small-cell lung cancers (NSCLC or SCLC), but its renal toxicity limits its use. Current guidelines recommend 24 h hydration: thus hospitalization is required. The aim of this retrospective study was to confirm the safety of short hydration before giving an intermediate-to-high dose of cisplatin in an outpatient clinic.Patients eligible had NSCLC or SCLC and were being treated with a chemotherapy regimen that included cisplatin ≥ 75 mg/m(2). They were given the same short hydration protocol for 1 day. Nephrotoxicity was defined as ≥ grade 1 according to NCIC common toxicity criteria. Predictive factors for nephrotoxicity were analyzed.Three hundred and fifty-seven consecutive patients (median age 58 years, range: 25-81) were reviewed. Twenty-one patients (6%) had ≥ grade 1 nephrotoxicity and all except one had grade 1 toxicity according to NCIC criteria for common toxicity (SC < 1,5 N). Predictive factors independently associated with nephrotoxicity included associated co-morbid conditions (hypertension, diabetes, heart disease) (OR = 4.97 CI 95% [1.8-13.7] P = 0.002), initial serum creatinine ≥ 100 μmol/L (OR = 8.3 CI 95% [2.55-27.4] P = 0.0005), and dose cycle of cisplatin ≥ 100 mg/m(2) (OR = 10.8 CI 95% [3.6-32.5] P < 0.0001).Rapid outpatient administration of a single dose of cisplatin at ≥ 75 mg/m(2) is feasible without a high risk of nephrotoxicity.
