Comparison of the role that poly hydroxy acrylic acid plays in the detection ofHER-2 gene in breast cancer by hematoxylin and eosin staining and fluorescence in situ hybridization with that of 4% neutral buffered formaldehyde
transparent dewaxing is an important step of hematoxylin eosin (HE) staining and fluorescence in situ hybridization (FISH) in detection of breast cancer HER-2 gene. The purpose of this study was to make a comparison
between poly hydroxyl acrylic acid which is an environmentally friendly fixation liquid and 4% neutral buffered formaldehyde in tissue fixation for HE staining and FISH to detect the HER-2 gene in the breast cancer tissue sections. The study aimed to evaluate the feasibility of replacing 4% buffered formaldehyde
a traditional fixation liquid
with the poly hydroxyl acrylic acid
an environmentally friendly fixation fluid. Methods: This project was performed on tissue samples collected from 69 cases of breast cancer
41 cases of breast fibroadenoma
40 cases of uterine leiomyoma
25 cases of cervical tissue
25 cases of placenta obtained from the outpatient and inpatient departments of Zhongshan Boai Hospital from Mar. 2011 to Jan. 2015
from each of which two samples were drawn and two blocks of each specimen were divided into two groups randomly. Then one group was fixed with 4% neutral buffered formaldehyde and made into 200 sections by HE while the other group was fixed with poly hydroxyl acrylic acid and made into another 200 sections. The slice level of the two groups was determined by the staining condition of the sections
and SPSS 19.0 was employed to compare the excellent and good rate of HE staining. Additional 69 sections were produced with two groups of breast invasive ductal carcinoma tissues
and SPSS 19.0 was used to detect the amplification of HER-2 gene by FISH. Results: First
the number of best-quality slices stained with HE fixed separately by poly hydroxyl acrylic acid and 4% neutral buffered formaldehyde was 155 and 166
respectively. The number of excellent pieces was 41 and 33
respectively
while the number of mediocre pieces was 3 and 1 with bad pieces being 1 and 0
respectively. The excellent and good rates of HE staining were 98% and 99.5%
respectively. There was no significant difference between the two groups (χ
2
=1.33
P0.05).Second
the positive rates of the tissue slices by FISH fixed separately by poly hydroxyl acrylic acid and 4% neutral buffered were 26.09% and 23.
19%
respectively. There was no significant difference between the two groups (χ
2
=0.50
P0.05).Conclusion: The results obtained with HE staining and FISH using poly hydroxyl acrylic acid as a fixation liquid are not significantly different from those using 10% neutral buffered formaldehyde. Therefore
poly hydroxyl acrylic acid meets the requirements of environmental protection
and thus has the potential to be promoted and widely used.
