Psycho-Oncology: When to Ask for a Cancer-Specific Therapist

Two findings from NCI's clinical summary on distress belong together.

First, most patients with cancer do not meet the criteria for any specific mental disorder. Second, many still go through a range of hard emotional responses.

Both are true at once. That is the reason a referral does not require a diagnosis.

NCI reports rates of distress that range from 22% to 58% across studies. Pooled results suggest that roughly 40% of patients report real distress.

Cancer type matters less than people expect. Patients with lung, pancreatic, and brain cancers do seem more likely to report distress. But NCI says the type of cancer is only modestly tied to it.

Three factors predict distress more strongly than the diagnosis itself:

• Disability.
• Poorer quality of life.
• Ongoing, unmet psychosocial needs.

That third item is worth sitting with. Unmet need is a predictor. So asking for help is part of the picture.

The word has a formal meaning here. It is broader than most people assume. NCI quotes a definition with several parts. Distress is an unpleasant experience that may be mental, social, spiritual, or physical. It can get in the way of coping with cancer, its symptoms, and its treatment.

The same definition describes a range. At one end sit common feelings of vulnerability, sadness, and fear. At the other sit disabling problems. Those include depression, anxiety, panic, social isolation, and a crisis of meaning or faith.

That range is the key idea. No sharp line turns feelings into a medical matter. Support applies along the whole range.

Ask whether the center screens for distress, and with what tool. The most studied one is the Distress Thermometer. The National Comprehensive Cancer Network developed it.

It is deliberately simple. Patients rate distress from 0 to 10. Zero is labeled no distress. Ten is labeled extreme distress. A checklist asks what has been a problem in the past week.

The threshold is published. A review and meta-analysis pooled 42 studies. A cutoff of 4 or higher worked best at spotting distress. Scores of 4 or more lined up with real anxiety and depression symptoms on the Hospital Anxiety and Depression Scale. NCI says a score of 4 or higher should prompt a talk with the oncology team. The point of that talk is to pick the right resource or referral.

For teens and young adults the cutoff may differ. A multi-country study of 288 patients in that age group found 5 or higher worked best. NCI notes that more research is needed.

NCI is unusually candid about the limits, and knowing this prevents a common misreading.

Very short tools like the Distress Thermometer have only modest accuracy. They are good at ruling distress out. They are poor at confirming it. Most screening tools throw a high number of false positives. Each needs a fuller interview to follow.

So a low score is not a verdict. And a high score is a prompt for a talk, not a diagnosis.

These are two separate processes, and knowing which one is happening clarifies a lot.

Screening is rapid. Staff who are not mental health professionals usually run it. They use a short self-report form to decide who needs a fuller look.

Psychosocial assessment is a longer clinical interview. A mental health professional runs it. It focuses on how well a person is coping and adapting.

The referral being requested here is for the second kind.

NCI lists predictors that are worth knowing, partly because several are not obvious.

One sample covered 380 patients with mixed diagnoses. Those scoring 4 or higher were more likely to be women. They also had poorer functional performance. And they reported more problems on the checklist. Those included housing, dealing with children, dealing with a partner, depression, fears, nervousness, sadness, worry, and 14 of 20 listed physical ailments.

One study followed 151 women with early-stage breast cancer. Physical symptoms and side effects during treatment predicted distress afterward. Other linked factors included younger age, non-White racial status, and less formal education. So did mastectomy rather than lumpectomy, hormonal treatment, and an existing mental health diagnosis at enrollment.

Another study followed 224 patients with head and neck cancer. Anxiety disorder right after treatment was more likely in two groups. Those were patients with advanced-stage disease and those with a history of childhood abuse.

One predictor stands out for distress a year or more later. It is a higher level of distress around the time of diagnosis. So early support is not premature.

Anxiety is not only unpleasant. NCI describes concrete ways it interacts with treatment.

It can raise the expectation of pain and other symptoms. It adds to sleep trouble. And it can be a major factor in anticipatory nausea and vomiting. That means nausea that starts before a chemotherapy dose is even given.

Anxiety also shapes behavior before any diagnosis. NCI gives one example. Some women with high anxiety learn they carry a higher genetic risk of breast cancer. They may then examine their breasts less often, not more.

Ask the oncologist, oncology nurse, or social worker directly. Most cancer centers have one of three things. A psycho-oncology service, a social work department, or a link to outside providers with cancer experience.

Keep the request concrete. Ask for a referral for psychosocial assessment. Or ask for a therapist who works with people in cancer treatment. If a distress screening was done, ask for the score. That gives the talk a starting point.

• Call 911 or go to an emergency department if you are thinking about ending your life, or you have a plan to hurt yourself. You can also call, text, or chat 988 to reach the Suicide and Crisis Lifeline, at any hour.
• Call your care team the same day if hopelessness has settled in and will not lift, panic keeps returning, or you have stopped eating, sleeping, or taking your cancer medicines.
• Call your care team within a day or two if distress has stayed high for a couple of weeks, or your screening score was 4 or higher and nobody has followed it up.
