Abstract
Background The prognostic value of p53 protein expression in esophageal cancer has been evaluated, but the results remain inconclusive and no consensus has yet been achieved. This meta-analysis was conducted to quantitatively assess the prognostic significance of p53 expression in esophageal cancer. Methods Publications that assessed the clinical or prognostic significance of p53 expression in esophageal cancer and were published before July 1, 2015 were identified by searching the PubMed and EMBASE databases. A meta-analysis was performed to clarify the association between p53 expression and the clinical outcomes. Results A total of 36 publications met the criteria and included 4577 cases. Analysis of these data showed that p53 expression in esophageal cancer was significantly associated with poorer 5-year survival (RR = 1.30, 95 % CI: 1.11–1.51, P = 0.0008). Subgroup analyses according to histological type, continent of the patients, and cut-off value revealed the similar results. The results also indicated that p53 expression was highly associated with advanced TNM stages (I/II vs. III/IV, OR = 0.74, 95 % CI: 0.55–0.99, P = 0.04), lymph node metastasis (OR = 0.77, 95 % CI: 0.66–0.90, P = 0.001), and distant metastasis (OR = 0.46, 95 % CI: 0.26–0.80, P = 0.006). However, p53 expression in the included studies was not significantly associated with tumor size (≤ 5 cm vs. > 5 cm, OR = 1.13, 95 % CI: 0.92–1.40, P = 0.24), tumor location (upper + middle vs. lower, OR = 0.91, 95 % CI: 0.70–1.17, P = 0.45), grade of differentiation (well + moderate vs. poor, OR = 1.10, 95 % CI: 0.90–1.34, P = 0.35), and the depth of invasion (T1/T2 vs. T3/T4, OR = 0.86, 95 % CI: 0.71–1.03, P = 0.09). Conclusions This meta-analysis showed that p53 expression may be a useful biomarker for predicting poorer prognosis in patients with esophageal cancer.

Abstract
This paper investigates the association between protein retinoblastoma (pRB) loss and the T,N stage and prognosis in esophageal squamous cell carcinomas (ESCCs) using meta-analysis. We conducted a meta-analysis of 16 studies, comprising 1,117 patients to clarify this issue. All the studies searched by the electronic literature PubMed and http://www.KJEBM.com, which had been published during the period from January 1996 to January 2012 according to the inclusion criteria. Summary odds ratios (OR) were calculated using fixed or random-effects models. The summary odds ratios (ORs) for pRB inactive were 0.64 (95% confidence interval [CI]:0.45-0.91, P = 0.01) for T1/T2 versus T3/T4 tumors; summary OR = 0.69 (95% CI:0.51-0.94, P = 0.02) for N0 versus N1 tumors. The association between pRB loss and prognosis was examined in nine studies, and the summary hazard ratio was 1.39 (95% CI:1.11-1.74, P = 0.004). pRB inactive was significant associated with T3/T4 tumors and N1 stage as well as adverse prognosis for ESCCs. It appears warranted to prospectively validate that pRB loss may be used for subdividing the T,N stage evaluation of patients with ESCCs, and these patients may be the preponderant people for individualized treatment or target therapy.

Abstract
OBJETIVO: Avaliar a expressão imunohistoquímica de p53 e ki-67 na carcinogênese esofágica induzida quimicamente através do uso de dietilnitrosamina, em um grupo de 100 camundongos fêmeas. MÉTODOS: O estudo experimental foi realizado com quatro grupos de animais, onde os grupos I e II foram considerados controles, sendo diferenciados por gavagem esofágica, uma vez semana, com água fria (temperatura ambiente) ou quente (60º-70ºC). E os grupos III e IV foram considerados estudos, os quais receberam dietilnitrosamina por três dias consecutivos semanalmente, também sendo diferenciados por gavagem, uma vez por semana, com água fria ou quente. O estudo apresentou datas progressivas de sacrifícios com coleta de peças esofágicas, que iniciava aos 30 dias de experimento e terminava aos 150 dias. Demonstrou-se que não houve diferença na incidência tumoral quando foi acrescida a variável temperatura da água; provavelmente devido ao episódio único semanal que era adicionado ao animal em experimentação. RESULTADOS: A análise imunohistoquímica do p53 não evidenciou diferença estatística durante a evolução da carcinogênese até 150 dias, porém quando analisado a relação com alterações patológicas demonstra-se que apresenta significância em relação à patologia baixo grau de displasia, alto grau e carcinoma. CONCLUSÃO: A análise imunohistoquímica do ki-67 demonstrou diferença estatística durante a evolução da carcinogênese a partir do dia 120 de experimento e quando analisada a relação com alterações patológicas demonstrou-se que apresenta significância também em relação à lesão intraepitelial de alto grau e carcinoma.

Abstract
AIMS Mutations in the gene coding for p53 protein are among the most frequent genetic alterations observed in human cancers. The relevance and biological significance of p53 expression in gastric carcinoma are far from being fully established. The aim of our study was to evaluate the influence of p53 detected by immunohistochemistry in the clinicopathological behaviour of a series of gastric carcinoma cases. METHODS AND RESULTS Samples from 163 patients treated by gastric resection for gastric carcinoma between 1988 and 1995 were used. Surgical specimens were evaluated for the presence of p53 protein detected by immunohistochemistry with a monoclonal antibody. Cases were classified as positive or negative for p53. Several clinicopathological parameters and c-erb B-2 expression were analysed in the same series and compared with the expression of p53. Cumulative survival was evaluated using univariate analysis and Cox model regression. p53 expression was identified in 41 carcinomas (25.2%) and was significantly associated with venous invasion (P = 0.049), lymph node metastases (P = 0.01) and c-erb B-2 expression (P = 0.003). All the parameters except gender, tumour size and Laurén's classification influenced survival on univariate analysis. p53 expression correlated with overall survival (P = 0.006) and survival in the subgroup of patients with intestinal type carcinoma (P = 0.04). In the subgroup of patients with carcinomas not expressing c-erb B-2, p53 expression significantly influenced cumulative survival (P = 0.02). CONCLUSIONS p53 expression is associated with the aggressive biological behaviour of gastric carcinomas and is related to cumulative survival.

Abstract
PURPOSE The aim of the current study was to find out the significance of the immunohistochemical expression of pRb2/p130, which is a member of the retinoblastoma gene family, in squamous cell carcinoma of the esophagus. METHODS We analyzed immunohistochemically the expression of pRb2/p130 of 107 squamous cell carcinomas (SCCs) of the esophagus and the correlation of pRb2/p130 expression with clinicopathological features was investigated. RESULTS Expression of pRb2/p130 was observed in 42 SCCs (39.3%). There was a significant correlation of pRb2/p130 expression with the histological type of well-differentiated SCC (P< 0.0001). The survival rate of patients with esophageal SCCs expressing pRb2/p130 was significantly better than that of patients with tumors without pRb2/p130 expression (P= 0.016). A multivariate analysis demonstrated that pRb2/p130 expression (P= 0.026), venous invasion (P= 0.028), and TNM stage (P= 0.044) were independent prognostic indicators in patients with esophageal SCCs. CONCLUSIONS Differentiation of esophageal SCC might be partially mediated by the pRb2/p130 gene, and pRb2/p130 expression can additionally be an indicator of the better prognosis of patients with esophageal SCCs.

Abstract
The pRb (p16-pRb-cyclin D1) and p53 (p53-MDM2-p21) pathways play a critical role in tumorigenesis. To evaluate which of these cell cycle regulatory proteins are related to patients' prognosis, a comprehensive analysis of alterations in these components was carried out in 100 ESCCs (oesophageal squamous cell carcinoma) using immunohistochemistry and correlated with clinicopathological parameters by univariate analysis. Overexpression of p53, MDM2 and cyclin D1 proteins was observed in 73, 42 and 67% of the cases, respectively, while loss of expression of p21, p16 and pRb was observed in 36, 45 and 75% of the cases, respectively. Multiple logistic regression analysis revealed that loss of p16 immunoreactivity was a significant risk factor for tumour stage (pT) (Odds Ratio (OR)=3.3), whereas the loss of pRb was a significant risk factor for nodal metastasis (pN) (OR=8.8). MDM2 overexpression emerged as the most significant risk factor for distant organ metastasis (pM) (OR=4.6). Of the ESCC patients who underwent oesophagectomy, 50 cases were followed-up for a maximum period of 44 months and median of 16 months. Survival analysis revealed that Cyclin D1 overexpression is an adverse prognosticator for disease-free survival, as well as overall survival, and tumour stage (pT) is an adverse prognosticator for disease-free survival. In conclusion, these data support a model of oesophageal cancer pathogenesis in which both the pRb and p53 pathways are inactivated and suggests an in-depth evaluation of the clinical utility of these putative markers is warranted.

Abstract
BACKGROUND The purpose of the present study was to examine the expression of cell cycle regulators [p53, p21WAF1/CIP1 (p21), and Rb] and apoptosis related proteins Bax and Bcl-X(L) and to evaluate the relationship between their expressions and clinicopathological findings in patients with superficial squamous cell carcinomas of the esophagus. METHODS We immunohistochemically investigated the expression of p53, p21, Rb, Bax, and Bcl-X(L) in 79 patients with superficial esophageal carcinoma. RESULTS p21 overexpression was found in mucosal carcinoma (P = 0.05) and a high Bcl-X(L) score was observed for submucosal carcinoma (P = 0.03). The patients with high Bcl-X(L) score had more frequent lymphatic invasion and lymph node metastasis than did those with low Bcl-X(L) score (P < 0.05). Univariate analysis revealed significantly shorter survival in patients with high Bcl-X(L) expression than in those with low Bcl-X(L) expression, but Bcl-X(L) expression was not identified as an independent prognostic factor by multivariate analysis. CONCLUSIONS Because Bcl-X(L) expression correlated well with depth of tumor invasion, lymphatic invasion, and lymph node metastasis, examination of Bcl-X(L) expression will help to estimate the properties in superficial squamous cell carcinoma of the esophagus.
