The association between post-treatment surveillance testing and survival in stage II and III colon cancer patients: An observational comparative effectiveness study

摘要

BackgroundThe best strategy for surveillance testing in stage II and III colon cancer patients following curative treatment is unknown. Previous randomized controlled trials have suffered from design limitations and yielded conflicting evidence. This observational comparative effectiveness research study was conducted to provide new evidence on the relationship between post-treatment surveillance testing and survival by overcoming the limitations of previous clinical trials.
