A Deeper Dive into Geriatric Assessment
While chronological age was once the primary factor in determining cancer treatment for older adults, the geriatric assessment (GA) has revolutionized this approach. It recognizes that a person's 'functional age'—their overall physical, mental, and social health—is a much more accurate predictor of their ability to tolerate and benefit from cancer therapy. By moving beyond a simple number, the GA enables oncologists to create treatment plans that prioritize both efficacy and quality of life.
The Core Domains of a Comprehensive Geriatric Assessment (CGA)
A comprehensive geriatric assessment (CGA) evaluates several key domains to create a holistic profile of the older patient. This multidimensional approach helps identify potential issues not seen in a standard oncology workup:
- Functional Status: Assesses daily living abilities.
- Comorbidity: Identifies other medical conditions.
- Nutritional Status: Checks for malnutrition risks.
- Psychological State: Evaluates mental health.
- Cognitive Function: Screens for cognitive issues.
- Social Support: Assesses support networks.
- Medication Review: Prevents drug interactions.
Comparing GA Screening Tools and the CGA
A two-tiered approach is often used, starting with a shorter screening tool to identify patients who may need a full CGA. This makes the process more efficient.
| Assessment Type | Purpose | Administration Time | Key Components | Outcome | Use Case | Benefits |
|---|---|---|---|---|---|---|
| Geriatric Screening Tool | Identifies high-risk older adults. | Brief (5-15 minutes). | Quick questionnaires (e.g., G8, VES-13). | Flags patients needing further assessment. | All older cancer patients (≥65). | Quick, high sensitivity, resource-efficient. |
| Comprehensive Geriatric Assessment (CGA) | In-depth, multidisciplinary evaluation. | Lengthy (60+ minutes). | In-depth tests across multiple domains. | Detailed patient profile, tailored recommendations. | High-risk patients identified by screening. | Reduces treatment side effects, optimizes care, improves communication. |
How the Geriatric Assessment Impacts Treatment Decisions
Research, including a study in The Lancet, indicates GA-guided treatment leads to fewer severe side effects and better quality of life for older chemotherapy patients, with comparable survival.
GA results influence decisions like:
- Treatment Modification: Adjusting therapy.
- Supportive Care: Referrals to specialists.
- Improved Communication: Better patient-family discussions.
- Clinical Trial Eligibility: Assessing fitness.
The Role of Different GA Tools in Practice
Common tools include:
- Geriatric-8 (G8): An eight-question screener.
- Vulnerable Elders Survey (VES-13): Identifies functional decline risk.
- Cancer and Aging Research Group (CARG) Chemotherapy Toxicity Risk Score: Predicts toxicity risk.
- National Comprehensive Cancer Network (NCCN) Guidelines: Offer a framework for CGAs.
Challenges and the Future of Geriatric Oncology
Implementing GA faces challenges like time and resources. Addressing these is key to making GA a standard practice for personalized care.

Conclusion
In essence, the geriatric assessment in oncology is a vital, multidimensional process that looks beyond age. It gives a full picture of an older patient's health, which is crucial for tailoring cancer treatment, reducing side effects, and improving quality of life. The increasing elderly population makes the broader use of GA vital for patient-centered care.
