Background: Regional-based studies have indicated that ethnicity is associated with presentation and outcome in patients with gastric adenocarcinoma. To validate this observation in a large cohort, the authors of this report used the National Cancer Data Base (NCDB) to determine whether self-reported ethnicity influences presentation and survival in this patient population.
Methods: Patient demographics, tumor-related features, and treatment-related features were analyzed by ethnicity.
Background: While the overall incidence of gastric cancer has declined in the United States of America, the incidence of proximal gastric cancers has increased. The purpose of this analysis was to highlight key differences between proximal and distal gastric cancer as they relate to presentation and treatment.
Methods: Data on 6,099 patients diagnosed with gastric adenocarcinoma were collected as a patient care evaluation under the auspices of the American College of Surgeons Commission on Cancer.
Background: Breast conservation therapy (BCT) and adjuvant hormonal therapy for estrogen-receptor positive breast cancers have become standard of care. Our objectives were to evaluate trends in the surgical management and adjuvant therapy for early-stage breast cancer and to identify factors predicting survival.
Methods: Using the National Cancer Data Base (NCDB), patients with node-negative breast cancers less than 1 cm (T1aN0M0 and T1bN0M0) from 1993-2004 were identified.
The concept that complex surgical procedures should be performed at high-volume centers to improve surgical morbidity and mortality is becoming widely accepted. We wanted to determine if there were differences in the treatment of patients with gastric cancer between community cancer centers and teaching hospitals in the United States. Data from the 2001 Gastric Cancer Patient Care Evaluation Study of the National Cancer Data Base comprising 6,047 patients with gastric adenocarcinoma treated at 691 hospitals were assessed.

It was officially recognized as a distinct pathologic diagnosis in 2000. With few published reports, we hypothesized that MBC may have markedly different characteristics at presentation than typical infiltrating ductal carcinoma (IDC) and may be managed differently.

Clinical trials represent the most powerful strategy for improving cancer treatments, but racial and ethnic minority patients are frequently underrepresented among patients accrued to these protocols. Proof of comparable efficacy for a promising cancer therapy in different groups of patients requires diversity in the clinical trial populations so that study results will be generalizable.
View Article and Find Full Text PDFObjective: To examine treatment trends in invasive lobular carcinoma (ILC) over the last 15 years and, in particular, to compare rates of recurrence and disease-free survival associated with breast conservation therapy compared with mastectomy.
Summary Background Data: The biologic characteristics of ILC make it difficult to estimate the extent of the disease by either clinical examination or mammography, and can also make it difficult to detect axillary lymph node metastases. Because of this, there has been a bias toward treating ILC with aggressive therapy.
