Longitudinal Changes in Immune Activation Serum Biomarkers Prior to Diagnosis and Risk of B-cell NHL Subtypes.

Background: To examine the contribution of B-cell activation molecules to B-cell follicular lymphoma (FL) and diffuse large B-cell lymphoma (DLBCL), a prospective study was conducted using pre-diagnosis serial serum samples from the US Department of Defense Serum Repository.

Methods: Each case (n = 142 FL, n = 211 DLBCL) was matched to two controls on age, gender, race, military branch, and blood collection dates. Immune activation molecules (IL1β, IL2, IL4, IL5, IL6, IL10, IL12, CXCL13, IL8, TNFα, IFNγ, GM-CSF, VEGF, sCD30, IgE) were quantified using ELISA or multiplex immunometric (Luminex) assay.

Evaluating sterile human acellular dermal matrix in immediate expander-based breast reconstruction: a multicenter, prospective, cohort study.

Background: Human acellular dermal matrices have gained increasing use in immediate expander-based breast reconstruction. However, some studies suggest that these grafts may be associated with a higher incidence of infection and seroma. To evaluate complication rates after matrix-based breast reconstruction, the authors conducted a prospective, multicenter, cohort study to evaluate a sterile human acellular dermal matrix in immediate expander-based breast reconstruction, specifically, to determine whether it offered a more favorable risk profile with respect to infection and seroma.

Rising thyroid cancer incidence in the United States by demographic and tumor characteristics, 1980-2005.

Thyroid cancer incidence has been rising in the United States, and this trend has often been attributed to heightened medical surveillance and the use of improved diagnostics. Thyroid cancer incidence varies by sex and race/ethnicity, and these factors also influence access to and utilization of healthcare. We therefore examined thyroid cancer incidence rates by demographic and tumor characteristics based on 48,403 thyroid cancer patients diagnosed during 1980-2005 from the Surveillance, Epidemiology and End Results program of the National Cancer Institute.

Lung cancer staging: a case for a new T definition.

Background: The purpose of this study is to determine a more refined T definition for lung cancer staging on the basis of clinical outcomes.

Methods: The Walter Reed Army Medical Center Tumor Registry and the Thoracic Surgery Tumor Clinic files were queried for lung cancers diagnosed from 1990 to 2000. Cox regression analysis and Kaplan-Meier survival curves for tumor size were used to analyze the impact of size on survival and relative risk, and then used to redefine T.

Unlimited access to care: effect on racial disparity and prognostic factors in lung cancer.

Study Objective: Evaluate the prognostic factors influencing lung cancer survival under a universal health care system and determine if access to care eliminates clinical outcome disparity.

Design: Retrospective case series review.

Background: Lung cancer survival is worse in men and in African Americans, thought to be related to poor general health in men and limited access to heath care in African Americans.

TP53 mutation spectrum in lung cancer is not different in women and men.

Whether women are more susceptible to lung cancer than men has been controversial. Several case-control studies suggested that women have greater risk of lung cancer compared with men at similar levels of cigarette smoking, whereas some large cohort studies failed to observe this association. Other studies indicated that lung cancer may have biological characteristics and mechanisms of carcinogenesis that are gender specific.

Polymorphisms in XPD and TP53 and mutation in human lung cancer.

The pattern of somatic mutations in TP53 is distinct for particular cancers and carcinogenic exposures, providing clues to disease etiology, e.g. G:C-->T:A mutations in TP53 are more frequently observed in smoking-associated lung cancers.
