Colorectal cancer (CRC) survivors report that diet and physical activity guidance from healthcare professionals following discharge from care is limited. Survivors seek advice from alternative sources. This study critically synthesised the English language diet and physical activity guidance available online for CRC survivors.
We conducted an internet search to identify national cancer organisations (NCO) in countries with high CRC incidence rates. We searched NCO website content for guidance related to diet and physical activity. Recommendations were categorised by cancer phase (prevention/survivorship), cancer type, and the intended outcome (health or cancer-control-CRC recurrence/CRC-specific mortality). A synthesised guideline was derived from recommendations consistently made by at least half of the sources.
We identified 12 NCOs from six countries, by whom 27 diet and physical activity recommendations were made. For CRC prevention, over 80% of recommendations were aimed at improving cancer-control outcomes. For CRC survivorship, less than 40% of recommendations were aimed at improving cancer-control outcomes. Physical activity was the only recommendation present on more than 50% of NCO websites aimed at improving cancer-control outcomes for CRC survivorship.
Diet and physical activity guidance for CRC survivors on NCO websites is limited and primarily based on recommendations for improving general health, not improving cancer-control outcomes. NCO websites frequently refer survivors to primary prevention guidance, potentially reflecting the lack of evidence specific to CRC survivorship. There is a need for diet and physical activity advice for survivors that is evidence-based, comprehensive, and consistent across organisations and tailored to specific cancer sites.
结直肠癌（CRC）幸存者报告称，他们在离开护理后从医疗保健专业人员那里获得的饮食和身体活动指导有限。幸存者会从其他来源寻求建议。本研究批判性地综合了 CRC 幸存者在线获取的英文饮食和身体活动指导。
我们进行了一次互联网搜索，以确定高 CRC 发病率国家的国家癌症组织（NCO）。我们在 NCO 网站内容中搜索与饮食和身体活动相关的指导。建议按癌症阶段（预防/生存）、癌症类型和预期结果（健康或癌症控制-CRC 复发/CRC 特异性死亡率）进行分类。从至少一半来源一致提出的建议中得出综合指南。
我们从六个国家确定了 12 个 NCO，这些 NCO 提出了 27 条饮食和身体活动建议。对于 CRC 的预防，超过 80%的建议旨在改善癌症控制的结果。对于 CRC 的生存，不到 40%的建议旨在改善癌症控制的结果。在旨在提高 CRC 生存的癌症控制结果的 NCO 网站上，只有身体活动的建议出现在超过 50%的网站上。
NCO 网站上针对 CRC 幸存者的饮食和身体活动指导有限，主要基于改善一般健康的建议，而不是改善癌症控制的结果。NCO 网站经常向幸存者推荐初级预防指南，这可能反映了缺乏针对 CRC 生存的具体证据。需要为幸存者提供基于证据、全面且在组织之间一致并针对特定癌症部位量身定制的饮食和身体活动建议。
