Area of Science:

• Oncology
• Clinical Nutrition
• Evidence-Based Medicine

Background:

• High variability exists in clinical nutrition practices for cancer patients, potentially affecting their nutritional status.
• Malnutrition is a significant concern in oncology, and standardized guidelines are needed to minimize its detrimental effects.
• Current clinical practice guidelines (CPGs) aim to reduce variability and improve patient outcomes through evidence-based recommendations.

Purpose of the Study:

• To review and summarize recommendations from major clinical practice guidelines on nutritional assessment and/or support for oncohematological patients.
• To identify inconsistencies in evidence quality assessment and recommendation grading across different guidelines.
• To highlight the importance of methodological quality and potential conflicts of interest in CPG development.

Main Methods:

• Systematic review of clinical practice guidelines published within the last 10 years.
• Inclusion of guidelines on nutritional assessment and/or support for oncohematological patients.
• Inclusion of high-quality guidelines from scientific societies not indexed in common databases like PubMed.

Main Results:

• Significant variability in the quality of evidence and recommendation grading systems used in current guidelines.
• Limited high-quality evidence available for some recommendations, impacting their direct applicability in daily clinical practice.
• Inconsistencies in guideline development and reporting, posing challenges for end-users in understanding and implementing recommendations.

Conclusions:

• High-quality clinical practice guidelines are crucial for standardizing oncology nutrition care and reducing malnutrition.
• Addressing the limitations in evidence quality, applicability, and consistency in guideline development is essential for effective implementation.
• Further research and standardized methodologies are needed to improve the quality and utility of CPGs in oncohematology.
