How Should Cancer-Related Distress, Anxiety and Feelings of Helplessness Be Treated?

What Is Cancer-Related Distress? Defining the Concept

According to the NCCN definition, cancer-related distress (CRD) is a multidimensional, unpleasant experience of a psychological (cognitive, behavioural or emotional), social, spiritual and/or physical nature. It can interfere with a person's ability to cope effectively with cancer, its physical symptoms and its treatment. Beyond this academic definition, however, distress appears in very concrete ways in everyday life: fatigue, persistent worry, sadness, fear, anxiety, loneliness, financial stress and uncertainty about the future.

As Dr. Jennifer Stevens, a triage and admissions nurse at Agrace Hospice in Madison, Wisconsin, explains, cancer-related distress affects almost every person with cancer to some extent, on a spectrum ranging from "simply feeling sad" to an "existential crisis". When it exceeds the threshold defined by standard assessment tools, distress is considered "clinically significant". Approximately 50% of patients experience severe or prolonged distress — in other words, half of patients, not merely a small minority, carry this burden.

Why Does It Matter? The Wide-Ranging Effects of Distress

Distress is not merely a matter of "morale". As shown in a systematic review published in 2024, distress is strongly associated with clinically meaningful outcomes: a higher symptom burden, greater healthcare use, faster disease progression, increased mortality and reduced treatment adherence. This last point is particularly important: successful cancer treatment depends heavily on the patient following the treatment regimen; a distressed patient may miss appointments, take medication irregularly or postpone follow-up tests.

As Prof. Brad Zebrack of the University of Michigan emphasises, distress can disrupt relationships and social participation, leading to social isolation . The patient's ties with family, friends and colleagues weaken — yet social support is precisely what is most needed during the cancer journey. As Prof. Sophia Kustas Smith of Duke University School of Nursing notes, distress also increases the risk of depression, anxiety and post-traumatic stress disorder (PTSD) . These effects can extend into survivorship and affect both the patient and caregivers.

NCCN Guideline Update: "Concerns", Not "Problems"

The changes in the NCCN Distress Management Guidelines published in January 2026 may appear superficial, but the underlying philosophy is profound. Two major terminology changes stand out:

Prof. Zebrack emphasises that this language change encourages understanding distress as a continuum, which may require different "doses" of intervention at different times. Stevens notes that the clinical impact of the change remains uncertain — many cancer centres will continue using the old version because of integration into electronic health records (EHR) — but that research and quality-improvement studies using the new PL (Problem List) will increase in the coming years.

Screening and Management: Evidence-Based Approaches

According to NCCN and American Society of Clinical Oncology (ASCO) guidelines, the highest standard of quality includes a comprehensive psychosocial assessment at diagnosis — carried out by a trained mental health professional, such as an oncology social worker — and ongoing clinical observation and distress screening throughout treatment and during the transition to post-treatment survivorship . Screening should be a process, not a "one-off" assessment.

One practical tool is the Distress Thermometer Problem List (PL) . This simple visual scale asks patients to rate their distress from 0-10 and indicate the areas in which they are struggling. Scores of 4 or above are generally considered the threshold for further assessment. However, as Dr. Stevens points out, research has shown that screening and referral alone are insufficient for most patients — the focus is now shifting from screening to management and follow-up after care .

Which Interventions Work?

Several approaches have demonstrated effectiveness in distress management. Prof. Smith emphasises that the strongest evidence base supports the following interventions:

In addition, psychoeducational support programmes, support with decision-making and problem-solving, peer support and referral to community-based cancer support organisations, such as Cancer Support Community and Blood Cancer United — formerly the Leukemia and Lymphoma Society — are among evidence-based approaches. For patients experiencing moderate-to-severe anxiety, PTSD or a depressive disorder, pharmacological treatment such as SSRIs may also be appropriate.

Digital Interventions: Addressing the Access Problem

Mental health workforce shortages, long waiting lists and geographical inequalities are worsening access problems in distress management. Prof. Smith notes that digital solutions are beginning to bridge this gap: mobile apps for cancer distress, web-based CBT programmes and hybrid coaching approaches. The Duke team's Cancer Distress Coach mobile app was used in a pilot study to manage post-traumatic stress symptoms and was found acceptable.

Emerging developments include the following: for personalised interventions, stepped-care and triage approaches; the expansion of digital and hybrid psychosocial interventions; integration into electronic health records of AI-assisted screening tools; and risk-prediction models for individualised distress management. These developments could transform the understanding of "standard care" in oncology practice in the coming years.

The Central Role of the Oncology Nurse

Both Prof. Smith and Dr. Stevens repeatedly emphasise the central role of oncology nurses in distress management. According to Prof. Smith, oncology nurses are the first peopleto notice emotional changes, shifts in coping capacity or early signs of becoming overwhelmed. Nurses can offer brief but effective strategies: motivational interviewing, supportive listening and coaching in basic coping skills.

According to research cited by Dr. Stevens, people with cancer are more likely to accept interventions delivered by nurses. This results from the close relationship nurses build with patients during day-to-day care. The deliberate use of the therapeutic relationship — building trust, validating emotions, normalising the experience of CRD and making space for reflection and meaning — is an effective starting point.

Smith also emphasises the importance of a trauma-informed approach — a perspective centred on safety, trust and patient empowerment. Appropriate assessment and care planning require attention to cultural, linguistic and contextual factors so that distress is understood in a meaningful and accessible way for each patient.

Current Gaps and Unresolved Issues

Despite the NCCN 2026 updates, significant gaps in distress management remain:

Managing Cancer-Related Distress in Clinical Practice in Türkiye

Distress management remains a developing field in oncology practice in Türkiye. Although support from psychologists and psychiatrists is available in large academic centres, medical schools and private oncology hospitals, access is very limited in medium-sized and smaller centres. The Distress Thermometer PL is not widely used in routine screening, and patients often receive no systematic distress assessment beyond being asked "how are you?".

There are several structural reasons for this. First, oncology nurses' workload is very heavy, and finding enough time for psychosocial assessment in addition to existing clinical care duties is difficult. Second, the number of patients per oncologist is high; there is no realistic time within a consultation to assess emotional wellbeing. Third, psycho-oncology is a relatively new and developing subspecialty in Türkiye, and there are not yet enough specialists. Fourth, stigma remains culturally powerful: many patients may withdraw when offered "mental health support".

There are, however, promising developments. Some large private cancer hospitals, such as Memorial Cancer Centers, are integrating multidisciplinary psycho-oncology teams into clinical workflows; the work of the Turkish Psycho-Oncology Association is increasing the field's capacity each year; and digital interventions, particularly Turkish-language mobile apps and web-based programmes, offer promise for overcoming access barriers. Brief distress-screening skills training for oncology nursesis a particularly feasible strategy in resource-limited settings such as Türkiye and should be expanded urgently.
