FUCHS-TARLOVSKY, Vanessa et al. Suplementación con antioxidantes no previene nefrotoxicidad por cisplatino en pacientes con cáncer cérvico uterino avanzado. Rev. venez. oncol. [online]. 2011, vol.23, n.1, pp.21-25. ISSN 0798-0582.

OBJECTIVE: In Mexico, our country, the pathology of cervical cancer is a major public health issue, the same situation is present in other American countries. The treatment for this pathology depends on its extension; for locally advanced stages, a combination of radiotherapy and chemotherapy with cisplatin drug is common used. The both therapies are considered to be pro oxidative and this can be implied in the toxicities of the treatment. The objective of this work was to determine the efficacy of antioxidant supplementation on the prevention of cisplatin drug in the renal toxicity. METHODS: We conducted a randomized clinical trial in the patients with locally advanced stage cervical cancer whose antineoplastic treatment consisted in radiation therapy and chemotherapy with the cisplatin drug. The patients were randomly assigned to receive either an antioxidant supplement or the placebo. We assessed renal function as creatinine clearance before and after concluding the oncologic treatment. We performed inter and intragroupal t-Student tests in order to determine the effect of the antioxidant supplementation on the evaluated parameters. RESULTS: No statistically significant differences we were found between the groups; however, there was a significant decrease in renal function in the both groups after finalizing the oncologic treatment. CONCLUSIONS: The antioxidant supplementation does not prevent the renal toxicity from the cisplatin drug chemotherapy.
