(Press-News.org) PLYMOUTH MEETING, PA [October 24, 2024] — New research published online-ahead-of-print in JNCCN—Journal of the National Comprehensive Cancer Network found that people with newly-diagnosed hormone receptor (HR)-negative, human epidermal growth factor receptor 2 (HER2)-positive breast cancer were more likely to receive timely, guideline-concordant treatment and have longer survival in states that participate in Medicaid expansion under the Affordable Care Act (ACA).
A team of researchers—led by the American Cancer Society (ACS), and including Kathryn J. Ruddy, MD, MPH, of the Mayo Clinic Comprehensive Cancer Center, a former NCCN Foundation® Young Investigator Award recipient—used data from the National Cancer Database (NCDB) to review results for women across the United States, age 18-62, who were diagnosed with this type of breast cancer between 2010 and 2018. 19,248 of the patients lived in Medicaid expansion states, while 12,153 resided in non-expansion locations. In the expansion states, the 2-year survival rate increased from the 2010 baseline rate of 93.9% to 95.0% across the study period. However, in the non-expansion states, 2-year survival declined slightly from 94.0% to 93.9%. The biggest difference was seen in patients with Stage III disease.
“Expanding Medicaid to the 10 states that have yet to do so can help ensure that more patients with cancer benefit from life-saving treatments,” said lead researcher Kewei Sylvia Shi, MPH, Surveillance and Health Equity Science, American Cancer Society. “It’s crucial to increase access to oncology services, expand insurance coverage, and streamline diagnostic and referral processes. Stage III cancer represents a critical point in disease presentation and can further progress and become incurable if undertreated. Having health insurance coverage will make it more likely for these patients to receive timely and comprehensive access to life-saving therapies, have better medication adherence, and complete treatment, which leads to better survival outcomes.”
HR-negative, HER2-positive breast cancer is an aggressive subtype that accounts for approximately 5% of all breast cancer diagnoses.1 This is the first study to focus on the impact of Medicaid expansion on that specific population.
The study found that treatment according to recommendations from evidence-based, expert consensus driven clinical practice guidelines—such as the National Comprehensive Cancer Network® (NCCN®) Clinical Practice Guidelines in Oncology (NCCN Guidelines®)— was more likely to begin within 90 days from diagnosis in the expansion states.
“This study reinforces the important role Medicaid expansion plays in ensuring that women newly diagnosed with HR-negative, HER2-positive breast cancer have equitable access to the healthcare services they need—especially when prognosis depends on access to treatment,” said Millicent Gorham, CEO of the Alliance for Women’s Health and Prevention, who was not involved in this research. “Breast cancer is far too common, and rates are increasing among younger women, making it critical that policymakers also prioritize women’s access to preventive health screenings and appropriate treatments.”

Decades after it was first found in Japan, a species of crustacean with unique black-and-white coloring that resembles a panda has been confirmed to be new to science. Melitid amphipods are shrimp-like crustaceans found worldwide. The newly classified Melita panda — named after the charismatic mammal — was first found in the 1990s. Details of the discovery and morphological analysis were published in a ZooKeys article on 21 September.
The discovery of the Melita panda highlights the importance of studying species taxonomy, which is the naming and classification of organisms, for conservation efforts. It is impossible to know if a species is in ...
BOSTON (Oct. 24, 2024) – With the rise in incidence of food allergies in children in the past decade, there has been a corresponding increase in the need for professional psychology services due to increased anxiety. A new study being presented at this year’s American College of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting in Boston showed a more than 50% increase in psychology referrals at one center in 2023 compared to yearly referrals from 2018-2022.
“Our center has devoted significant resources to address the psychosocial support needed by many families who have children with food allergies,” ...
BOSTON (Oct. 24, 2024) – Anaphylaxis can come on suddenly and without warning, and because its symptoms can be fatal, it is scary for those who encounter it. Two new studies being presented at this year’s American College of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting in Boston show it is not only patients and caregivers who misunderstand how best to treat anaphylaxis: emergency medical professionals often follow incorrect protocols for treating severe allergic reactions.
“We know early recognition of anaphylaxis and treatment with epinephrine improves outcomes,” says Sasha Alvarado, DO, Co-Director of Quality ...
BOSTON (Oct. 24, 2024) – About 10% of Americans believe they are allergic to penicillin, and approximately 90% of those patients are not actually allergic. As a result, those with the penicillin allergy label are often prescribed more toxic, dangerous and expensive antibiotics that might not be necessary or effective. A new study being presented at this year’s American College of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting in Boston showed that syphilis patients labeled as penicillin allergic who are low risk should be delabeled to avoid treatment failure and other negative ...
BOSTON (Oct. 24, 2024) – In many cultures, it is common to burn incense for religious and cultural practices, including meditations, celebrations and spiritual and ancestral worship. A new medically challenging case being presented at this year’s American College of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting in Boston warns that, for those with allergies and asthma, health problems from burning incense can be a significant risk to adults and children.

BOSTON (Oct. 24, 2024) – Parents of children with atopic dermatitis (AD, also called eczema) know that the allergic condition can mean a heightened risk of developing food allergies. The desire to prevent food allergies causes some parents to consider elimination diets, cutting out certain foods from their child’s diet. A new study being presented at this year’s American College of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting in Boston showed that elimination diets in the case ...
BOSTON (Oct. 24, 2024) – Throughout the Covid pandemic, media widely reported that Black patients were more likely than White patients to refuse vaccines, including the influenza and Covid vaccines. A new study being presented at this year’s American College of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting in Boston showed that self-identified non-White patients were less likely to demonstrate vaccine-hesitancy than the self-identified White patient group.
“We found ...
