Aging With Cancer & Geriatric Oncology

Most people diagnosed with cancer in the United States are older adults. But age alone says very little about how someone will handle treatment. Two people in their late seventies can be in entirely different positions. One still drives, gardens and lives alone. The other manages heart failure, diabetes and a walker. Geriatric oncology is the part of cancer care built around that difference. It does not ask how old someone is. It asks what their body and their life can absorb.

The goal is not automatically gentler treatment. It is treatment matched to the person. Sometimes that means full-strength therapy. Sometimes it means a modified plan.

A geriatric assessment is a structured review. It goes well beyond the usual oncology workup. It is largely questionnaire-based. The patient or a family member can complete much of it before the visit.

The American Society of Clinical Oncology updated its geriatric oncology guideline in 2023. It recommends that management be guided by a geriatric assessment in patients with cancer aged 65 and older who have impairments identified by that assessment. The guideline describes assessment across several domains. Those include physical and cognitive function, other medical conditions, emotional health, nutrition, polypharmacy and social support. The update also extended the earlier recommendation beyond chemotherapy. It now takes in targeted therapy and immunotherapy.

Those domains matter because they predict problems better than a doctor's impression across a desk. Can someone climb stairs? Have they fallen in the past six months? Are they losing weight? Is there anyone at home to call at 2am? Those answers tell you more about how they will tolerate treatment than their birth year does.

Your cancer center may not offer one. It is reasonable to ask whether a geriatric assessment or a referral to a geriatrician is available.

Polypharmacy means taking many medicines at once. Many older adults arrive at oncology already taking a long list. Different clinicians prescribed them over many years. Supplements nobody has reviewed sit on top of that. Then cancer drugs are added.

Interactions are common and often preventable. Some supplements interfere with cancer treatment. Some long-standing prescriptions no longer serve a purpose. An oncology pharmacist is usually the best person to sort this out. Most cancer centers have one.

Practical steps that help:

• Bring every bottle to the first appointment. That means prescriptions, over-the-counter medicines, vitamins and herbal supplements. A list from memory is not enough.
• Ask specifically for a pharmacist medication review before treatment starts.
• Ask which of your existing medicines could be stopped or reduced during treatment, and which must not be.
• Keep one written list. Update it after every appointment. Give a copy to whoever might take you to an emergency room.
• Ask which side effects mean calling the team straight away rather than waiting for the next visit.

For many older adults the real question is not survival in the abstract. It is whether they will still be able to live at home, drive, and manage without becoming dependent. That is a legitimate thing to say out loud in a treatment discussion. A good oncologist will treat it as clinical information, not sentiment.

Worth asking: how many appointments per week will this involve, and for how long? What is the chance this treatment lands me in the hospital? Will I still be able to drive? What happens to my strength? Can physical therapy be part of the plan? Our list of questions to ask before treatment begins is a useful starting point to adapt.

Survival figures deserve care here. Statistics from clinical trials often come from patients younger and fitter than the person in the room. Other health conditions change the picture a great deal. Our explanation of what a five-year survival rate actually means may help when those numbers come up.

Care for an older adult with cancer often lands on a spouse. That spouse may have their own health problems. Or it lands on an adult child managing it from another state. That arrangement strains quickly. Palliative care can be brought in alongside active treatment. It manages symptoms and coordinates care. It is not the same as stopping treatment. Our page on caregiver burnout is written for the people doing the driving and the pill sorting.

Growing older with cancer means holding two things at once. Cancer is serious. And it is not the only thing that will shape the coming years. Good geriatric oncology keeps both in view rather than pretending either one away.
