To improve accuracy of the immunohistochemical testing and fluorescence in situ hybridization (FISH) study as well as a routine histology diagnosis in breast cancer, quality improvement for optimal tissue handling is mandatory. We evaluate fraction defective of 7107 blocks from 349 breast cancer patients, who underwent surgical treatment at Samsung Medical Center Seoul, Korea from January 1, 2009 to March 31, 2010. We decided pre-improvement period from January, 2009 to June, 2009. In the first quality improvement period (July, 2009 to September, 2009) we made improvements in protocol of gross examination. In the second quality improvement period (October, 2009 to December, 2009) we attempted more effective formalin fixation such as frequent exchange of formalin and use of separate fixation container for each case. In the third quality improvement period (January, 2010 to March, 2010) improvement of tissue processor was performed. We achieved a marked reduction of fraction defective (9-16%) through efforts to improve quality of formalin-fixed, paraffin-embedded blocks when compared to pre-improvement period.

A bone marrow biopsy that has undergone decalcification with 10% nitric acid could not be used for various pathological tests and had extremely limited reproducibility. The fixing solution of each experimental group was differentiated in usage, one solution including acid and the other not. The use of the decalcification solution was separated into either acidic or alkaline (EDTA), and further experiments were conducted with differing time phases. When using a fixing solution and decalcification solution which included acid, the specimens were faulty to the extent that all pathological tests were impossible. However specimens that were processed with an EDTA type decalcification solution did not display a non-specific reaction in EBV ISH and were even able to produce results that were at a level suited to various studies or a pathological diagnosis in the FISH, DNA, RNA tests. By improving the fixing and decalcification of bone marrow biopsy, the study was able to make possible ISH, FISH, DNA tests as well as RNA study, and secured the sensitivity, specificity, and reproducibility of various test methods. The stabilization of various test methods that use bone marrow biopsy contributes to the diagnosis, prognosis, prediction, treatment of the patient and provide guidelines for decision-making.
