While 30 of 32 (94%) cases in differentiated nonkeratinizing carcinoma (NKC, WHO type 2) and 16 of 17 (94%) cases in undifferentiated carcinoma (UC, WHO type 3) showed EBERs expression, neither five cases of keratinizing squamous cell carcinoma (KSCC, WHO type 1) nor two cases of adenocarcinoma showed EBERs. bcl-2 protein was detected in 50 (89%) cases, but its expression did not depend on expression of LMP1. p53 protein was detected in 31 (55%) cases, and there was a correlation between expression of EBERs and p53 protein (P < 0.05) but not between LMP1 and p53 protein.

Since p53 is commonly mutated in colorectal cancers, but rarely in those tumours showing microsatellite instability (MSI), the aim of this study was to examine the relationship of bcl-2 protein expression to MSI, as well as to other clinicopathological and molecular variables, in colorectal adenocarcinomas.

Fatty acid synthase was associated with ADC (P = 0.0001). p53 protein was associated with high-grade dysplasia adenoma (AHGD), ADC (P = 0.0001), and pT stage (P = 0.003). bcl-2 was associated with adenomas with low-grade dysplasia (P = 0.009); c-myc was associated with ANNM (P = 0.005) and pT stage (P = 0.006). p21-ras was associated with AHGD (P = 0.0001) and ANNM (P = 0.01).

These data agree with earlier reports that bcl-2 staining is less common in adenocarcinomas; however, our data do not support the hypothesis that bcl-2 staining confers a better prognosis overall, in squamous cell carcinoma, or in an older patient population.

We conclude that wild-type p53 protein acts as an active suppressor in the regulation of the baseline growth and cell kinetics of this tumour and could be linked through a p53--bcl-2 system in human endometrial adenocarcinomas.

p53 was not correlated to any patient or tumor characteristic, whereas bcl-2 showed higher expression in squamous cell carcinomas (P < .001). bax expression was significantly related with male sex (P = .006) and adenocarcinoma type (P = .0013). p53 status, assessed with one monoclonal antibody (MoAb), was not predictive for survival; however, the combination of staining results obtained with two MoAbs identified the DO7-/PAb1801+ tumors as those with the worst prognosis. bcl-2 expression was associated with longer survival in stage I patients (P = .0169).

In this study, 42 prostatic adenocarcinomas were analyzed to determine whether increased bcl-2 levels are associated with rearrangements in the 2.8-kb major breakpoint region, an association known to occur in certain follicular lymphomas featuring a t(14:18) translocation.

The results of this study show that bcl-2 is relatively highly expressed in proliferative (n = 11) and hyperplastic (n = 18) endometrium, with respective mean staining scores of 3.59 and 3.47 (scale, 0-4), but is significantly (P < 0.001) down-regulated in atypical hyperplasia (n = 11; score, 0.82), and adenocarcinoma (n = 34; score, 0.86). bcl-2 expression did not correlate with stage, grade, estrogen-receptor, or progesterone-receptor expression.
