Short answer: Supportive care in cancer is the prevention and management of the adverse effects of cancer and its treatment (MASCC). It runs from diagnosis through treatment, rehabilitation, survivorship and end-of-life care, and it is wider than palliative care. This page is general information for researchers and clinic staff, not medical advice.
Definition and scope
The Multinational Association of Supportive Care in Cancer (MASCC) defines supportive care in cancer as the prevention and management of the adverse effects of cancer and its treatment. MASCC’s fuller wording adds that this includes management of physical and psychological symptoms and side effects across the continuum of the cancer journey, from diagnosis through treatment to post-treatment care, and that it aims to improve the quality of rehabilitation, secondary cancer prevention, survivorship and end-of-life care.
MASCC’s public description lists the domains it covers: physical and psychological symptoms and treatment toxicities; communication among people with cancer, caregivers and clinicians; helping people tolerate active therapy; the emotional and psychosocial burden on patients and caregivers; and psychosocial support for survivors.
A 2023 open-access review in Cancers (15(15):3860), which describes supportive care as the ‘keystone’ of modern oncology practice, summarises four MASCC principles: supportive care maintains or improves quality of life and lets people get the maximum benefit from anticancer treatment; it is relevant across the whole continuum; it is coordinated, person-centred and guided by individual preferences, and includes family and friends; and it is a basic right that should be available in all cancer centres and facilities that routinely manage people with cancer.
How supportive care is used in practice
The same review quotes the US National Cancer Institute’s wording: care given to improve quality of life by preventing or treating, as early as possible, the symptoms of the disease and the side effects of its treatment, including physical, psychological, social and spiritual support for patients and families. It lists examples such as pain management, nutritional support, counselling, exercise, music therapy, meditation and palliative care, and says supportive care may be given alongside other treatments from diagnosis until the end of life.
The review notes that supportive care draws on a range of specialist teams and services rather than a single department. For adverse-event grading in trials and clinics, see the Common Terminology Criteria for Adverse Events (CTCAE); for patient-reported symptom measurement, see what PROMs are.
Supportive care, palliative care and ‘best supportive care’ compared
| Term | What the source says | Source |
|---|---|---|
| Supportive care (MASCC) | Prevention and management of the adverse effects of cancer and its treatment, across the continuum from diagnosis to end of life. | MASCC, ‘What is Supportive Care?’ |
| Supportive care (NCI, as quoted) | Care to improve quality of life by preventing or treating symptoms and treatment side effects as early as possible; may be given with other treatments from diagnosis until the end of life. | Quoted in Cancers 2023;15(15):3860 |
| Palliative care (IAHPC, as summarised) | Active holistic care of individuals with serious health-related suffering due to severe illness, especially near the end of life; improves quality of life of patients, families and caregivers. | Cancers 2023;15(15):3860 |
| Best supportive care | Sometimes used interchangeably with supportive care, which the review calls ‘somewhat of a misnomer’; historically the control arm in many trials, often meaning no specific care. | Cancers 2023;15(15):3860 |
The review’s position is that palliative care is an integral component of supportive care, while supportive care is much more than palliative care. It also reports that some specialist palliative services have rebranded as ‘supportive care’ because ‘palliative’ is often perceived as meaning end-of-life care, and that the name change can increase referrals and bring them earlier in the patient’s journey.
Where it matters for trials and clinic operations
The review summarises expert consensus standards for best supportive care in trials in advanced cancer. They can be read as a protocol-review checklist:
- Multidisciplinary access: palliative specialists available during anticancer therapy, plus nursing, social work, and financial and spiritual counselling.
- Documentation: institutional review boards should review protocols for supportive-care documentation when it is significant; supportive care should be delivered and documented in a standard way; journal editors should ask for a clear description of what best supportive care entailed.
- Symptom assessment: at baseline and regularly, with concise validated tools, at identical assessment intervals in both arms.
- Symptom management: following evidence-based guidelines.
Functional status is often recorded alongside symptoms; see the Karnofsky Performance Status and Palliative Performance Scale guides. For the supplies side of a palliative unit, see the palliative care unit supply checklist, and for the specialty context, what oncology is.
Common misunderstandings
- ‘Supportive care means end-of-life care.’ Both MASCC and the NCI wording place it from diagnosis onward, alongside active treatment.
- ‘Supportive care and palliative care are the same.’ The 2023 review treats palliative care as one component of a broader supportive-care field.
- ‘Best supportive care is a standard package.’ The review says the term has often meant no specific care in control arms, which is why the consensus standards ask for documented, standardised delivery.
FAQ
What is supportive care in cancer?
MASCC defines it as the prevention and management of the adverse effects of cancer and its treatment, from diagnosis through treatment, survivorship and end-of-life care.
Is supportive care only for people near the end of life?
No. MASCC and the NCI wording quoted in the 2023 review both describe it as available from the time of diagnosis, including alongside active anticancer treatment.
How does supportive care differ from palliative care?
The 2023 review describes palliative care as an integral component of supportive care, and supportive care as involving a wider range of specialist teams and services.
What does ‘best supportive care’ mean in a clinical trial?
It is sometimes used interchangeably with supportive care, but historically it often meant no specific care in a control arm. Consensus standards ask for multidisciplinary access, documentation, regular symptom assessment at identical intervals in both arms, and evidence-based symptom management.
