BACKGROUND
Although the safety of combination chemotherapy without primary tumor resection (PTR) in patients with stage IV colon cancer has been established, questions remain regarding a potential survival benefit with PTR. The objective of this study was to compare mortality rates in patients who had colon cancer with unresectable metastases who did and did not undergo PTR.
METHODS
An observational...
BACKGROUND
A key challenge to mining electronic health records for mammography research is the preponderance of unstructured narrative text, which strikingly limits usable output. The imaging characteristics of breast cancer subtypes have been described previously, but without standardization of parameters for data mining.
METHODS
The authors searched the enterprise‐wide data warehouse at the Houston...
BACKGROUNDT‐cell lymphomas (TCLs) are uncommon in the United States. The accurate diagnosis of TCL is challenging and requires morphologic interpretation, immunophenotyping, and molecular techniques. The authors compared pathologic diagnoses at referring centers with diagnoses from expert hematopathology review to determine concordance rates and to characterize the usefulness of second‐opinion pathology...
BACKGROUNDNeoadjuvant chemoradiotherapy followed by tumor resection and postoperative chemotherapy is the standard of care for patients with clinical stage II or III adenocarcinoma of the rectum. Significant variation exists in the receipt of postoperative chemotherapy after resection in this population. The objective of this study was to determine the demographic and clinicopathologic factors associated...
BACKGROUNDWeekly or daily cisplatin and 5‐fluorouracil (5‐FU)‐based chemoradiation was evaluated for patients with locally advanced squamous cell carcinoma (SCC) of the anal canal treated at a single institution over a 20‐year period.
METHODSA retrospective, single‐institution analysis was conducted of patients receiving concurrent 5‐FU/cisplatin and radiotherapy for locally advanced SCC from 1989...
BACKGROUNDStem cell transplant (SCT)‐related outcomes and prognostication for relapsed/refractory follicular lymphoma (FL) are not well‐defined in the post‐rituximab era.
METHODSThrough the National Comprehensive Cancer Network (NCCN) lymphoma outcomes study, 184 patients with relapsed/refractory FL who underwent autologous SCT (autoSCT) or allogenic SCT (alloSCT) following disease relapse after...
BACKGROUND:Little is known about the utility of central nervous system (CNS) prophylaxis for diffuse large B‐cell lymphoma (DLBCL) in the rituximab era. The objective of this study was to characterize patterns of CNS prophylaxis for patients who received combined rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R‐CHOP) chemotherapy using the National Comprehensive Cancer Network...
BACKGROUND:Preoperative chemoradiation for rectal cancer can decrease the number of evaluable lymph nodes. Hence, the prognostic role of lymph node evaluation in patients with rectal cancer who receive preoperative chemoradiation is unclear. The authors of this report evaluated the prognostic impact of the number of lymph nodes examined in patients with rectal cancer who had negative lymph nodes based...
BACKGROUND:In 2007, the US Food and Drug Administration (FDA) issued regulatory alerts for use of erythropoiesis‐stimulating agents (ESAs) in cancer patients with anemia after clinical trials and meta‐analysis data found that high ESA doses were associated with adverse outcomes in patients. In response to these findings, specific patient management tools for anemia (consisting in an algorithm and...
BACKGROUND:African‐American women have increased breast cancer mortality compared with white women. Diagnostic and treatment gaps may contribute to this disparity.
METHODS:In this retrospective, longitudinal cohort study, Southern US health plan claims data and linked medical charts were used to identify racial disparities in the diagnoses, treatment, and mortality of commercially insured women with...
