Our patient had none of the classic predisposing factors for hepatic lymphocytic proliferation, such as chronic viral hepatitis, HIV, EBV or autoimmune hepatic disease. However, other mechanisms for the development of NHL in celiac disease may be implicated. It is also possible that this may be an entirely fortuitous association.

In the United States, colorectal cancer (CRC) is the third most common incident cancer and the third highest cause of cancer death for both men and women (1). When CRC is diagnosed at an early stage, the 5-year relative survival is 90.4%, but for patients with metastatic disease, 5-year survival Inhibitors,research,lifescience,medical is only 11.6% (2). Factors associated with stage at presentation and survival include race (3), gender (3), socioeconomic status (SES) (4,5), and molecular abnormalities, such as abnormal expression of p53 (6). Although SES has emerged as an important factor relating to CRC, the mechanism through which it affects survival Inhibitors,research,lifescience,medical has not been ABT-869 datasheet elucidated. There is a need to identify genetic factors that contribute to SES differences and to progression of CRCs. Genetic alterations, including those in the p53 gene, occur during the development of CRCs (7). Patients whose CRCs exhibit nuclear accumulation of p53 (p53nac) have decreased survival
Inhibitors,research,lifescience,medical after resection, and p53nac may be a useful Inhibitors,research,lifescience,medical prognostic factor (8,9). Although patient race/ethnicity and SES are related, they do not measure the same construct
(10). Therefore, it is important to determine if SES and race are associated with p53nac. Environmental factors associated with SES may be related to the genetic alterations in carcinogenesis. For women with breast cancer, p53 mutations were associated with SES Inhibitors,research,lifescience,medical and may have an association with the poorer prognosis of women of low SES (11). Thus, there is a need to identify the genetic factors that contribute to SES differences and progression of CRCs. This study aimed to evaluate the association between measures of SES, including health insurance and employment status, and p53nac among a cohort of patients with CRC. Patients and methods Patients An existing database for a cohort of patients (N=1,135) who received curative or palliative resection for sporadic CRC at the University of Alabama at Birmingham from 1981 to 2002 was utilized for this study. This investigation, which no was approved by the Institutional Review Board at the University of Alabama at Birmingham, did not require informed consent. The data were obtained from medical records, physician charts, and surgical pathology and radiology reports. For a subset of patients, archival tissues were obtained and evaluated for p53nac status (N=590). Only patients with data on both SES and p53nac status were included for this analysis (N=249).
