The 60% of tumors affected patients >65years of age and the future previsions are considering an amount of 70% after 2030. Elderly Patients presents multiple comorbidity, polipharmacy, and disability. Geriatric assessment helps physicians to take the best therapeutic decisions. Clinical conditions influence efficacy and tolerability of chemotherapy. Prophylactic use of G-CSF after chemotherapy lowers the rate and length of severe neutropenia , and decreases the episodes of febrile neutropenia. Anemia is a hematologic condition associated with ageing , but is frequently associated to concomitant chronic disease. Stem cells display increasing resistance to erythropoietin in the elderly patients and this is connected with the onset of pro-inflammatory cytokines characteristic of this age . Anemia is a common adverse event in cancer patients receiving chemotherapy. Several of the symptoms associated with anemia, such as fatigue, syncope, palpitations and dyspnea, reduce patient activity and have a profound effect on the quality of life [QOL]. Considering the unfit or frail status of elderly patient the at home use of pegfilgrastim and weekly or three weekly erythropoietin administration could be preferred for this setting of patients that lack of specialized nursing care or facilities. Further studies, considering the several differences in health organizations in vary countries, could be held to state the real impact of the biosimilars in comparison to the long acting originators in the reduction of costs in this group of patients.
