Cochrane review: early palliative care in advanced cancer
Early palliative care for adults with advanced cancer.
Overview
Haun MW et al.. Cochrane Database Syst Rev 2017 · PMID 28603881 · DOI 10.1002/14651858.CD011129.pub2
Early palliative care slightly improved quality of life and symptoms; any survival effect is uncertain.
Does the study support the specific claim? Partly · Methodological quality: high
Plain-language summary
Study explained simply
- What did the researchers want to find out?
Summarise trials of early palliative care
- How was the study done?
Cochrane systematic review
- How many people, animals or samples were studied?
7 trials, 1614 adults
- What was actually found?
Small quality-of-life gain; survival unclear
- How large was the observed effect?
QoL SMD 0.27; survival HR 0.85 (0.56-1.28)
- What do the results mean in everyday life?
Palliative care helps people feel better; it is given alongside, not instead of, cancer treatment
- What are the study's limitations?
Few, unblinded trials
- What does it say about Elawady's specific claim?
Supports the quality-of-life part; does not confirm longer survival
- Do the results apply to Germany and Europe?
High
- What can explicitly not be concluded from this study?
Cannot show that palliative care replaces anticancer treatment

2. Research question
Does early palliative care improve quality of life, depression, symptoms and survival in advanced cancer compared with usual care?
3. Study design and population
- Study design
- Meta-analysis – Cochrane systematic review and meta-analysis of RCTs and cluster RCTs
- Population
Adults with advanced cancer
- Country
International
- Period
Search to October 2016
- Sample size
7 trials, 1614 participants
- Inclusion and exclusion criteria
RCTs/cRCTs of professional early palliative care services
4. Methods and endpoints
- Exposure / intervention
Early palliative care (specialist or coordinated care)
- Comparator
Usual/standard oncology care
- Endpoints
Health-related quality of life, survival, depression, symptom intensity, adverse events
- Statistical methods
Random-effects inverse-variance meta-analysis; SMD; GRADE
5. Actual results
- Results
Quality of life SMD 0.27 (0.15-0.38), low certainty (FACT-G +4.59 points); survival HR 0.85 (0.56-1.28), very low certainty (4 studies, 800 participants); depression SMD -0.11 (-0.26 to 0.03), very low certainty; symptom intensity SMD -0.23 (-0.35 to -0.10), low certainty.
- Absolute risks
not reported as absolute survival difference
- Authors' conclusion
Early palliative care may improve quality of life and symptoms with small effect sizes; effects on mortality and depression are uncertain.
6. Strengths
- Cochrane methods, GRADE
- Pre-specified outcomes
- Includes Temel 2010 and later trials
7. Weaknesses
- Few trials; heterogeneous interventions
- Lack of blinding
- Survival data from only 4 studies
8. Risk of bias
- Orienting tool
- AMSTAR 2
- Type of assessment
- simplified assessment (abstract only)
- Full formal assessment
- no
- Overall risk of bias
- low
- Rationale
Cochrane review; evidence base itself low to very low certainty.
9. Assessment of the statistical interpretation
HR 0.85 (0.56-1.28) is log-symmetric and wide: compatible with 44% lower or 28% higher hazard (stats/C-CHM-07.py).
10. Relevance to the specific claim
Confirms the quality-of-life part of the claim (small benefit) but shows the survival benefit reported by Temel 2010 has not been confirmed across trials.
11. Independent contrary findings
Temel 2010 (A-CHM-16) single-centre survival gain.
12. Transferability to Germany and Europe
Applicable; early palliative care is standard in European guidance.
13. Overall methodological judgement
Early palliative care improves quality of life modestly; survival effect uncertain.

15. Linked fact checks
- At the end of life, chemotherapy often does not help, and early palliative care improves quality of life and even survival (Temel 2010). – Studies contradicting or limiting the claim
