Inter-Guideline Comparison
As expected, significant agreement in scientific content
International guidelines:
More general Slower/longer process of integrating newer regimens

TREATMENT GUIDELINES FOR ADJUVANT THERAPY OF BREAST CANCER
• Aim : to enhance individual clinical decision-making • Evidence : from clinical trials / metaanalysis
Eg, in 9 guidelines on NSCLC included in the analysis, the concordance was > 80% (80-98%)
Heterogeneity reflects
Different development groups and intended focus Differences in diagnostic and treatment approach by country Different resources available Different uptake of the new approaches Different level of patient involvement in the decision making process
