Phase 2 study aiming to assess the protective effect of mangafodipir against the oxaliplatine neuropathy.Population: Cancer patient who have a mild (grade 2) oxaliplatin neuropathy and in whom the continuation of oxaliplatin for at least 4 infusions is desirable will be include, whatever the location of the primitive tumor and the use of others anticancer agents.Treatment: Mangafodipir (0.5 ml/kg) is administered as a 30 minutes infusion just after each administration of oxaliplatin. The oxaliplatin dose (85 to 100 mg/m²) and the length of the infusion (2 hours) are the same that before the inclusion and modifications are not authorized during all the study participation. Primary objective: Neuropathy are clinically evaluated according to NCI-CTC criteria before each mangafodipir and oxaliplatin and thereafter one month after the last infusion. The primary criteria is the worst grade of oxaliplatin neuropathy experienced by each patient. The improvement of neuropathy is defined as a decrease by at least one grade of the severity of the neuropathy for at least 2 months.
