(Press-News.org) Study’s findings suggest that detecting and treating depression are critical to patient health.
In a recent study, having depression before or after a breast cancer diagnosis was associated with a lower likelihood of survival. The findings are published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society.
For the study, Bin Huang, DrPH, of the University of Kentucky Markey Cancer Center, and his colleagues analyzed data from the Kentucky Cancer Registry to identify adult women diagnosed with primary invasive breast cancer in 2007–2011. Utilizing the health claims–linked cancer registry data, the team classified patients as having no depression diagnosis, depression diagnosis only before cancer diagnosis, depression diagnosis only after cancer diagnosis, or persistent depression defined as depression before and after cancer diagnosis. The team also assessed patients’ receipt of first course guideline-recommended treatment as indicated by the National Comprehensive Cancer Network breast cancer treatment guidelines.
Among 6,054 patients, 4.1%, 3.7%, and 6.2% of patients had persistent depression, depression pre-diagnosis only, and depression post-diagnosis only, respectively. Analyses indicated that 29.2% of patients did not receive guideline-recommended breast cancer treatment. Also, during a median follow-up of 4 years, 26.3% of patients died.
Compared with patients with no depression, patients with post-diagnosis only or persistent depression had a similar likelihood of receiving guideline-recommended treatment, but patients with depression pre-diagnosis only had 25% lower odds of receiving guideline-concordant care, although this finding was marginally significant. Additional research is needed to determine the potential reasons for this association.
Depression pre-diagnosis only and depression post-diagnosis only (but not persistent depression) were linked with worse survival compared with no depression. Specifically, depression pre-diagnosis was associated with a 26% higher risk of death, and depression post-diagnosis was associated with a 50% higher risk. Also, patients who did not receive guideline-recommended treatment faced a 118% higher risk of death than those who received recommended care.
Compared with patients residing in non-Appalachian Kentucky, patients residing in Appalachia were 18% less likely to received recommended care, but investigators did not find any significant differences in survival.
The findings suggest that diagnosing and treating depression at the time of breast cancer diagnosis and beyond can be critical to patient care and survival.
“A surprising result from this study is that patients with persistent depression did not experience worse survival compared with patients with no depression,” said Dr. Huang. “Given that under-diagnosis and under-treatment of depression are common among cancer patients, persistent depression could be an indication that patients’ depression may have been well managed. Hence, this particular result suggests the importance of depression screening and management throughout a cancer patient’s care.”
Dr. Huang noted that population-based cancer registry data enhance population-based cancer outcomes research. “Utilizing linked health claims data and cancer registry data in this study demonstrated the value of data linkages across various sources for examining potential health disparities and identifying where improvements in cancer care are needed,” he said. “More rigorous studies are needed in depression management and across various cancer sites and patient populations. Subsequently, results from these research studies may further shape policies and guidelines for depression management in cancer care.”

Teen jobs: Some parents cautious about negative impact on grades, sleep and social life
2023-04-17
For many teens, that first formal job as a fast-food cashier, barista or lifeguard is a rite of passage.
And while some families tout the positives of job experiences, such as improving their teen’s money management skills and self-esteem, others worry about the potential to negatively impact sleep, schedules and grades, according to the University of Michigan Health C.S.

ARRS Annual Meeting: 4D flow MRI, 3D phantoms benefit atrial fibrillation patients
2023-04-17
Honolulu, HI | April 17, 2023—Findings from an award-winning Scientific Online Poster presented during the 2023 ARRS Annual Meeting at the Hawaiian Convention Center suggest that correctly occluded left atrial appendages (LAAs) could present maximal reduction in left atrial (LA) flow stasis and thrombogenicity, offering a clinical goal for the procedure in patients with atrial fibrillation.
Pointing out the paucity of knowledge in atrial fibrillation (AF) populations regarding the actual flow dynamic changes before and after percutaneous left atrial appendage occlusion (LAAO), “we aimed to evaluate LA flow dynamics for pre-occluded, correctly occluded, and incorrectly ...

Connections in the brain involved in epileptic seizures identified
2023-04-17
Researchers at the UCL Queen Square Institute of Neurology have discovered a network of connections in the brain linked to seizures in people with epilepsy.
The team believe that their findings, published in Brain, will help redesign neurological operations for patients whose epilepsy can’t be controlled by medication. By disconnecting certain pathways in the frontal lobe, patients may be able to enjoy long-lasting freedom from seizures.
There are 500,000 people in the UK with epilepsy and 50 million people have the condition worldwide. But one in three cannot ...
New details of Tully monster revealed
2023-04-17
For more than half a century, the Tully monster (Tullimonstrum gregarium), an enigmatic animal that lived about 300 million years ago, has confounded paleontologists, with its strange anatomy making it difficult to classify. Recently, a group of researchers proposed a hypothesis that Tullimonstrum was a vertebrate similar to cyclostomes (jawless fish like lamprey and hagfish). If it was, then the Tully monster would potentially fill a gap in the evolutionary history of early vertebrates. Studies ...
Environmental toxin PCB found in deep sea trench
2023-04-17
PCB has been banned in most countries since the 1970s, but that doesn't mean it no longer exists. Now, deep-sea researchers report that they have found PCB at the bottom of the Atacama Trench in the Pacific Ocean.
During their expedition to the deep-sea trench, the research team retrieved sediment cores and analyzed them for PCB occurrences at five different locations in the trench. All the samples of surface sediment analyzed contained PCB.
The study, led by Professor Anna Sobek from the Department of Environmental Science at Stockholm University and Professor Ronnie N. Glud, director of the Danish Center for Hadal Research at ...
