Systematic Review of Evidence database of NCCN 2026 Breast Cancer Guidelines

We are conducting a systematic review of the clinical evidence database underpinning the NCCN Guidelines for Breast Cancer Version 4.2026, with the primary objective of mapping critical evidence gaps.

Objective: To identify the "Resource-Evidence Gap" by analyzing whether the guideline's preferred standards are globally representative to even lower to middle income states or just limited to high income settings with advanced medical infrastructure. Only those who are genuinely interested in dedicating their time should apply. Participants will have to analyze cited studies, identify representation gaps, evaluate demographic reporting, compare guideline evidence bases, investigate research questions regarding bias in medical evidence, and handle manuscript drafting and revisions. The goal is to get this published, so each participant must commit to staying on board through the entire process, not just the initial drafting, but also the revision stages up until final publication. Our goal is to publish within 3-4 months. None of us are experts yet, so we will learn and navigate this together. But the only acceptable behaviors are mutual respect and ethical practice.
