- Brief Summary
Prediction of chemotherapy toxicity and survival in elderly (aged ≥65 years old) patients with advanced solid tumors receiving systemic chemotherapy by using CARG risk score.
- Detailed Description
Elderly patients (age ≥65 years) with cancer represent a growing proportion of patients in oncology clinical practice, primarily due to increasing life-spans as well as medical progress contributing to decreased morbidity and mortality from other causes.
Treatment decision-making for elderly patients with advanced cancer is often more complex than decision-making in younger cancer patients. The elderly population is heterogeneous in terms of their overall health status beyond their cancer diagnosis.
The risk of severe chemotherapy toxicity is one of the most important factors oncologists consider when recommending a treatment plan, and in elderly patients with advanced cancers, 25% to 60% of patients are treated with a planned dose reduction for their first chemotherapy cycle. These dose reductions are usually made on the basis of chronologic age and ECOG performance status, variables well known to be poor predictors of chemotherapy toxicity risk and tolerability of treatment.
Clinical prediction tools provide physicians with more accurate means for identifying patients who are at low or high risk of adverse outcomes.
The cancer Aging Research Group (CARG) risk score, developed by Hurria and colleagues, is a validated geriatric assessment tool that predicts for significant chemotherapy-related toxicities (grades 3-5) in older North American adults aged ≥65 years starting on chemotherapy.
The CARG score uses 5 key geriatric assessment (GA) domains, selected laboratory test values, age, tumor type, and treatment intensity to categorize patients into 3 risk groups for severe chemotherapy toxicity (grade 3-5): low risk (score 0-5; 30% grade 3-5 toxicity), medium risk (score 6-9; 52%), or high risk (score ≥10; 83%).
The CARG risk score has been validated in other countries and in specific tumour sites to varying degrees. It is included in ASCO Guideline and NCCN guidelines for Geriatric Oncology to predict severe chemotherapy-related toxicity. However its applicability in Egyptian patients is unknown as geriatric assessment is not routinely used for elderly patients.
The investigators may provide an evidence for validating the CARG risk score in Elderly patients with advanced solid tumors receiving systemic chemotherapy.

Group Intervention Description Elderly patients calculating CARG score Elderly patients (aged ≥65 year's old) planned to receive first-line chemotherapy for advanced solid tumor malignancies, presenting to the clinical oncology department, Assiut University Hospitals, Assiut, Egypt.
- Primary Outcome Measures
Name Time Method Prediction of grade 3-5 chemotherapy toxicity risk in elderly patients (aged ≥65 years old) with advanced solid tumors by measurement of CARG risk score (Cancer and Aging Research Group). 6 months follow up in first line chemotherapy in the advanced setting
- Secondary Outcome Measures
Name Time Method Correlation of the physician measured ECOG PS with grade 3-5 toxicities. 6 months follow up in first line chemotherapy in the advanced setting Correlation between the CARG score and 2 year OS (overall survival). 2 years it will be measured from the start of chemotherapy to death or censored at the last clinic visit
Correlation between the CARG score and 2 year PFS (progression free survival). 2 years it will be measured from the time from start of first-line chemotherapy to disease progression or, censored at last clinic visit)
