A proposed metric of quality of cancer care is whether chemotherapy is administered in the last 14 days of life. In a retrospective study of patients at The University of Texas MD Anderson Cancer Center reported in JAMA Internal Medicine, Rodriguez et al found an overall rate of chemotherapy use in ...
The effect of false-positive mammograms on women undergoing screening is being investigated by the U.S. Preventive Services Task Force. In a study reported in JAMA Internal Medicine, Tosteson et al assessed responses to false-positive screening mammograms. According to the authors, their findings...
In a prospective cohort study reported in JAMA Internal Medicine, Li et al found that recent and ever use of sildenafil for erectile dysfunction was associated with increased risk of subsequent melanoma, but not squamous cell or basal cell carcinoma. The RAS/RAF/MAPK and ERK kinase/ERK cascade is...
In a cohort study reported in JAMA Internal Medicine, Reimers et al found that aspirin use was associated with a significant 47% reduction in mortality risk after diagnosis of colon cancer expressing HLA class I antigen. There was no difference in aspirin benefit according to strong or weak...
As reported in a research letter in JAMA Internal Medicine, Sun et al studied the frequency with which women lead clinical trial publications from organized collaborative groups in oncology. They found that women are very infrequently lead or corresponding authors, with the percentages not changing ...
Although it is recommended that women aged ≥ 75 years be informed of the benefits and risks of mammography before being screened, it appears that this is not common practice. As reported in JAMA Internal Medicine by Schonberg et al, a decision aid developed by the investigators helped improved...
In a recent study published in Science Translational Medicine, Davila et al found that 88% of patients with relapsed or refractory B-cell acute lymphoblastic leukemia (ALL) who were treated with genetically modified versions of their own immune cells achieved overall complete response. Most...
Oral ascorbate, or vitamin C, has been shown to be ineffective in cancer clinical trials. However, recent studies have indicated that millimolar concentrations of ascorbate achieved in blood and tissue with intravenous dosing is associated with cancer cell killing without harm to normal tissue. In...
In a research letter published in JAMA Internal Medicine, Chinn et al surveyed physicians’ attitudes towards hospice treatment if they were terminally ill with cancer and assessed how physician preferences might affect timing of hospice discussions with their terminally ill patients. They...
In a study reported in JAMA Internal Medicine, Patz et al of the NLST Overdiagnosis Manuscript Writing Team estimated the magnitude of overdiagnosis using low-dose computed tomography (CT) screening for lung cancer in the National Lung Screening Trial (NLST). They estimated that more than 18% of...
In a study reported in JAMA Internal Medicine, Smith-Bindman et al evaluated the ability of ultrasound imaging characteristics to determine risk of thyroid cancer associated with thyroid nodules. They found that a strategy of using two abnormal nodule characteristics as an indication for biopsy...
Results of a Johns Hopkins study may explain why cyclophosphamide prevents graft-vs-host disease in people who receive bone marrow transplants. The experiments point to an immune system cell that evades the toxic effects of cyclophosphamide and protects patients from a lethal form of graft-vs-host...
A recent study by Darby and colleagues showed a significant linear increase in risk for major coronary events according to mean cardiac dose of radiation (7.4% per Gy) in patients receiving radiation therapy for breast cancer between 1958 and 2001. In an analysis reported in a research letter...
Young women with breast cancer may overestimate the risk that cancer will occur in their other healthy breast and decide to undergo contralateral prophylactic mastectomy, a survey conducted by Dana-Farber Cancer Institute investigators indicated. The survey also shows that many patients may opt for ...
The level of expression of three genes associated with aging can be used to predict whether seemingly low-risk prostate cancer will remain slow-growing, according to researchers at the Herbert Irving Comprehensive Cancer Center at Columbia University Medical Center (CUMC). Use of this three-gene...
Genomic sequencing experts at Johns Hopkins partnered with pharmacologists at Stony Brook University to reveal a striking mutational signature of upper urinary tract cancers caused by aristolochic acid, a plant compound contained in herbal remedies used for thousands of years to treat a variety of...
Organized mailing campaigns could substantially increase colorectal cancer screening among uninsured patients, according to a study published online in JAMA Internal Medicine. The research also suggested that a noninvasive colorectal screening approach, such as a fecal immunochemical test, might be ...
Long-term use of a calcium-channel blocker to treat hypertension is associated with higher breast cancer risk, according to a report published by JAMA Internal Medicine. The study assessed the relationships between the major classes of hypertensive agents and risk of the two most common histologic...
