Improvements noted in cancer recurrence data reporting quality

A significant decline in cancer recurrence data missingness was observed from 2004 to 2021, with reduction rates of 7.3% for breast and 11.5% for pancreatic cancers. However, challenges persist, notably inadequate physician documentation and interpretation variability. Factors such as driving distance and geographic location contributed to increased missingness, with surveys indicating that 67.8% of respondents cited documentation issues. Multi-organizational efforts are being initiated to enhance data abstraction processes for better outcomes research support.
