From: "Summary Page": a novel tool that reduces omitted data in research databases
Example of a possible error highlighted by the " Summary Page ". This breast cancer patient was treated with lumpectomy (excisional biopsy) followed by XRT. Subsequently after no events are recorded for year and a half she has a modified radical mastectomy. This could indicate a possible error (e.g. omitted date of cancer relapse). However, the error is not definite as sometimes patients request a more comprehensive surgery on their own without overt clinical indications.
