- چکیده:
- چکیده انگلیسی: Breast cancer is the most common cause of death among women worldwide. Although there are many known risk
factors in breast cancer development, infectious diseases have appeared as one of the important key to contribute to
carcinogenesis formation. The effects of Human Cytomegalovirus (HCMV) on women with breast cancer has been
recently studied and reported. To contribute to this research trend, this study was conducted to evaluate the association
between HCMV and the women with breast cancer. Objective: This experiment aimed to evaluate HCMV DNA in women
with breast cancer in Ahvaz city, Iran. Materials and Methods: A total of 37 formalin fixed paraffin embedded tissues of
the patients with ductal breast carcinoma and 35 paraffin embedded tissues of the patients with fibro adenoma as control
group were collected. The deparaffinization of all the samples were carried out and the DNA was extracted. Initially,
the PCR test was carried out to detect beta –globulin DNA as an internal control. For those samples positive for beta
–globulin DNA, Polymerase Chain reaction (PCR) was used to detect HCMV for the tests and control samples. Results:
Among 37 ductal breast carcinoma, 20 (54.04%) cases were proved positive for HCMV DNA by PCR. While among
the 35 control group (fibroadenoma), 10 (28.57%) cases were positive for HCMV DNA (P >0.028). The prevalences of
HCMV DNA among the age groups 30-39, 40-49 and >50 years were 7 (72.22%), 9 (69.23%), 4 (57.14%), respectively
(P=0.066). A high frequency of HCMV DNA was detected in tumor grade III, 13/18 (58.33%) compared with tumor
grade II, 7/19 (36.84%) (p=0.044). A high frequency of 16/24 (66.66%) of HCMV DNA was found in invasive ductal
breast cancer compared with 4/13 (30.76%) HCMV DNA in situ (P<0.028). Conclusion: A high prevalence of 54.05%
HCMV was found among the patients with ductal carcinoma. The percentages of the high prevalence of HCMV among
age group (40-49) years, tumors grades, and invasive stage were (69.23%), (58.33%), (66.66%), respectively. Further
study of HCMV in the latency phase in patients with ductal carcinoma would be necessary to extend our knowledge.- انتشار مقاله: 22-06-1397

- چکیده:
- چکیده انگلیسی: Background: Ductal carcinoma is one of the most common breast cancer (BrC) among the women in the world.
Several factors may involve in establishment of breast cancer. The role of viral infections have been investigated in
BrC, Among them the association of Epstein Barr virus have been reported in the patients with breast cancer type
ductal carcinoma. Thus this study was conducted to evaluate the rate of Epstein Barr virus in women with breast cancer
type ductal carcinoma. Material and methods: A total of 72 formalin-fixed paraffin-embedded tissue blocks samples
were collected from 37 (51.38%) women with breast cancer type ductal carcinoma and 35 (48.61%) samples of breast
with fibro adenoma as control group. The DNA was extracted for all the samples. The detection of EBNA 3C EBV
DNA was done by nested PCR. The results of positive were sequenced to confirm PCR product and determine EBV
genotypes. Results: About 10/37 (27.02%) samples of ductal breast carcinoma were showed positive for EBNA 3C
EBV DNA while 4/35 (11.42%) of fibro adenoma were positive for EBNA 3C EBV DNA (p= 0.095). Randomly 7
PCR products were sequenced and the results of sequencing EBNA 3C shows, the detected EBVDNA were type 1
EBV type. Conclusion: This study shows high prevalence of 27.02% EBV DNA type 1 was found in formalin-fixed
paraffin-embedded tissue of Patients with ductal breast carcinoma. The outcomes of this study suggesting that EBV
might have a significant role in breast cancer in Ahvaz city, south west region of Iran. However the expression of EBV
oncoproteins ,EBNA1, LMP1, and LMP2 require to be determined with ductal carcinoma cells. About 72.97% breast
samples showed negative for EBVDNA. The role other viruses including Human cytomegalovirus, papilloma viruses
and Merkel viruses are required to be investigated in further studies.- انتشار مقاله: 12-06-1396
