Do surgeon-specific mortality data disguise wider failings in delivery of safe surgical services?
The study showed that most deaths cannot be prevented by the operating surgeon. They occurred through issues of patient comorbidity, lack of process or infrastructure. This casts doubt on SSMD publication alone as a tool for quality improvement. In contrast, POCMA and FTR highlight problems of process, and are more likely to promote advances in surgical care.
Cells with secretory changes contain p63 protein or an antigenic equivalent. The detection of p63 protein continues to have considerable value for the identification of myoepithelial cells and thus the determination of invasion, but will also have value in the determination of secretory carcinomas of the breast and in understanding their development.
