The role of geriatric assessment prior to chemotherapy in elderly patients with cancer

Abstract

The decision to treat elderly patients with cancer aged 70 years or older with chemotherapy is generally based on clinical judgment of the clinician, in combination with the evidence obtained from clinical studies performed in younger age groups. The instrument GA might be helpful to detect hidden shortcomings and may aid clinical decision making with regard to the feasibility of treatment with chemotherapy and prediction of survival in the elderly patients with cancer. The following questionnaires and tests were considered appropriate to obtain a practical GA: MNA, GFI, IQCODE, MMSE, and laboratory values of albumin, creatinine, lactate dehydrogenase and hemoglobin. The main questions we tried to answer were firstly to assess the predictive value prior to the start of chemotherapy of the chosen GA with respect to the probability to complete the planned chemotherapy and overall survival and secondly to analyze and determine which elements of the chosen GA were independently predictive to complete chemotherapy and which elements predicted early mortality.This thesis is the result of clinical research on certain elements of GA that might be useful for routine daily oncology practice, in order to select the proper patients and improve the outcome of treatment with chemotherapy.
