We evaluated clinical features and survival outcomes among patients with signet ring and mucinous histologies of colorectal adenocarcinoma by using data from the National Cancer Data Base (NCDB). Patients aged 18–90 years with colorectal adenocarcinoma diagnosed between 1998 and 2002 were identified from the NCDB. Site-stratified (colon vs. rectum) survival(More)
PURPOSE Neoadjuvant chemoradiotherapy for rectal cancer is associated with improved local control and may result in complete tumor response. Associations between tumor response and disease control following radical resection should be established before tumor response is used to evaluate treatment strategies. The purpose of this study was to assess and(More)
BACKGROUND Despite increased demand for contralateral prophylactic mastectomy (CPM), the survival benefit of this procedure remains uncertain. METHODS We used the Surveillance, Epidemiology, and End Results database to identify 107 106 women with breast cancer who had undergone mastectomy for treatment between 1998 and 2003 and a subset of 8902 women who(More)
OBJECTIVE To calculate conditional survival estimates for patients with pancreatic adenocarcinoma. DESIGN We constructed separate multivariate survival models adjusted for 7 clinicopathologic factors for patients who did and did not undergo radical surgical resection. PARTICIPANTS Patients with pancreatic adenocarcinoma diagnosed between 1988 and 2005(More)
BACKGROUND The presence of distant metastases and the completeness of resection are important prognostic factors in patients with small bowel adenocarcinoma (SBA); however, the influence of lymph node metastasis on patient outcome has not been well characterized. The objective of the current study was to evaluate the impact of the number of positive and(More)
BACKGROUND The current study was conducted to determine whether quantified pathologic response assessed as a percentage of residual tumor cells is predictive of recurrence-free survival (RFS) in patients with rectal cancer. METHODS The authors studied 251 patients with rectal adenocarcinoma who were treated with neoadjuvant chemoradiation and radical(More)
BACKGROUND The objective of the current study was to examine the impact of adherence to guidelines on stage-specific survival outcomes in patients with stage III and high-risk stage II colon cancer. The National Comprehensive Cancer Network (NCCN) has established working, expert consensus, and evidence-based guidelines for organ-specific cancer care,(More)
PURPOSE Conditional survival (CS) estimates provide important prognostic information for clinicians and patients who have survived a period after diagnosis. In this study we performed a contemporary evaluation of conditional survival among colon cancer patients and created a browser-based tool for real-time determination of conditional survival(More)
BACKGROUND Cancer registries use algorithms to process cause of death (COD) data from death certificates, but uncertainties remain regarding the accuracy and utility of those data in calculating cancer-specific survival (CSS). Because it is impractical to reconfirm the COD through meticulous review of the primary medical records, the observed cancer deaths(More)
BACKGROUND Traditionally, for patients with colorectal cancer with resectable synchronous liver metastases, resections were performed separately. However, the safety and efficacy of simultaneous resection have been demonstrated in selected patients. The purpose of this study was to evaluate outcomes and economic implications of simultaneous and staged(More)
