Abstract

Background:
Cancer is highly prevalent in those above the age of 65 years. Elderly oncological patients are under-represented in clinical trials and there is a lack of clinical data to guide treatment decisions in this group of patients. We evaluated the cytotoxic treatment tolerability in this group of patients in a community hospital.
Methods:
Cytotoxic chemotherapies and tyrosine kinase inhibitors administered in Gold Coast Hospital to patients above 65 years of age between March 2010 and March 2011 were included. Data including number of comorbidities, concurrent medicines, ECOG status and treatment drug dose adjustment were obtained. The outcomes of treatment including treatment completion, early termination and its reason, toxicities and hospital admissions during treatment were also collected.
Results:
A total of 206 patients were identified. Majority had an ECOG score of 0 to 1 (89%) and number of co-morbidities between 0 and 3 (96%). Eighty percent of patients had initial or subsequent treatment dose reduction. Despite this, 53% of patients (n=109) did not complete the planned treatment; 68% had disease progression but 31% was due to treatment intolerance. There was a high number of reported grade 3 and 4 toxicities (n=84) and hospitalisations during treatment (n=154).
Conclusions:
There is a high rate of dose reduction and noncompletion of cytotoxic treatments even in a relatively healthy elderly population. We propose further prospective study incorporating in-depth geriatric assessment to evaluate elderly patients suitability for cytotoxic treatments.
