Abstract：Objective To summarize the experience in the management of pathological specimens for the bone tumor boundary study, and to provide references for the management of pathological specimens for the bone tumor boundary study.Methods From 2012 to 2014, the procedures of collecting, processing and transferring pathological specimens for the bone tumor boundary study were focused on. In the collecting step, great attention was pained to the choice of spicemen bags, and a method of multiple copies of different volumes of pathological specimens was adopted. In the processing step, security was concerned, including personnel security, specimen security and environmental security. At least 2 staff members were requested to check and sign in the transferring step. A total of 800 specimens collected from 2012 to 2014 were selected as the improved group, and 800 specimens from 2000 to 2011 as the control group. And the error rate was compared between the 2 groups.Results Errors were detected in 7 cases in the improved group, and the error rate was 0.875%. While errors were noticed in 67 cases in the control group, and the error rate was 8.375%. The differences in the error rate were statistically significant between the 2 groups (P<0.05 ). Obvious improvement was achieved, especially in the incomplete and inaccurate specimen information, insufifcient amount of liquid specimens immersed in, mismatched specimen bags and specimen bags not strickly packaged (P<0.05 ).Conclusions In the management of pathological specimens for the bone tumor boundary study, especially in the management of a large number of pathological specimens with a lot of staff members involved and a long processing cycle, the rules should be strictly followed and controlled. In each step, at least 2 staff members should face to face check the specimen information and then sign, so as to reduce the errors because of the operation performed by a singel man, avoid mistakes and improve the accuracy in the management of specimens.
