ABSTRACT
Objective To investigate the expressions and clinical significance of Ki-67,p53,and survivin in esophageal cancer and precancerosis.Methods The expressions of Ki-67,p53,and survivin proteins were detected by immunohistochemical staining in 40 normal esophageal mucosa,136 precancerosis (42 mild atypical hyperplasia,43 moderate atypical hyperplasia,and 51 severe atypical hyperplasia),and 68 esophageal cancer tissues.The correlation of three proteins expressed in esophageal carcinoma tissues was analyzed.Results The positive expression rate of Ki-67 was 0 (0/40)for normal epithelium,35.7％ (15/42) for mild dysplasia,51.2％ (22/43) for moderate dysplasia,74.5％ (38/51) for severe dysplasia,92.6％ (63/68) for squamous carcinoma,respectively.The positive expression rate of p53 protein was 0 (0/40) for normal epithelium,28.6％ (12/42) for mild dysplasia,46.5％ (20/43) for moderate dysplasia,52.9％ (27/51) for severe dysplasia,67.6％ (46/68) for squamous carcinoma,respectively.The positive expression rate of survivin protein was 0 (0/40) for normal epithelium,38.1％ (16/42) for mild dysplasia,55.8％ (24/43) for moderate dysplasia,64.7％ (33/51) for severe dysplasia,89.7％ (61/68) for squamous carcinoma,respectively.Rank correlation analysis showed that abnormal expressions of Ki-67,p53,and survivin were correlated significantly with the pathological grading of the lesions (r =0.637,0.454,0.590,P ＜0.01).The expressions of Ki-67,p53,and survivin were positively correlated in esophageal carcinoma (r =0.407,0.646,P ＜ 0.01).Conclusions The abnormal expressions of Ki67,p53,and survivin were associated with the processes of the esophageal canceration,and the joint detection with three parameters has important clinical value.
ABSTRACT
ObjectiveTo investigate the expressions of folate receptor alpha (FOLR1) in 40 esophageal cancerous tissues and its relevance of ABO blood group.MethodsABO blood groups were analyzed in 40 patients.Immunohistochemistry (IHC) and real-time quantitative reverse transcription PCR detection were used to detect the expression of folate receptor in cancer and adjacent tissues.Results20％of esophageal cancer was suspected positive (+), 50％ of cancer adjacent tissue was suspected positive (+), 10％ were positive (+), the difference was statistically significant (x2 = 14.48, P ＜0.01).Real Time RT-PCR analysis showed FOLRI low expression in esophageal cancer and adjacent tissues, compared to normal esophageal mucosa, the differences were statistically significant (F1 =53.247, F2 = 116.500, P ＜0.01).ABO blood type and FOLRi in esophageal cancer patients were not significant correlated (P =0.647, P ＞0.05).ConclusionsFOLRI expression was decreased in the esophageal lesions compared with adjacent tissues.Detection of FOLRl expression level in esophageal cancerous tissues and the paired adjacent tissues was helpful for judging the extent of disease and guiding surgery treatment.The FOLRI expression level in esophageal carcinoma tissues had no relationship with ABO blood types.
ABSTRACT
Objective To investigate the expression of extracellular matrix metalloproteinase inducer (CD147), nuclear factor kappa B (NF-κB) in esophageal squamous cell carcinoma tissue and probe their relationship to invasion and metastasis of esophageal carcinoma. Methods Immunochemical staining was performed to detect the expression of CD147 and NF-κB protein in 40 cases of esophageal carcinoma tissues and 40 cases of normal control. Results The positive rate of CD147 and NF-κB in esophageal carcinoma tissues and in adjacent noncancerous tissues were 77.5%/87.5% Vs 25%/42. 5%, P＜0.05.The positive rate of their prophase and metaphase-advanced stage esophageal carcinoma tissues were 33.3%/90.3% Vs 55.6%/96.8%, P＜0.05..The positive rate of non-metastatic and metastatic esophageal carcinoma tissues were 28.6%/87.9% Vs 42.9%/97%, P＜0.05.Conclusions Our results suggested that the increased expression of CD147 and NF-κB contributed to tumor angiogenesis in esophageal squamous cell carcinoma, which might be through the common pathway.
