Blacks have less access to cancer specialists, treatment

The study, published online in the Journal of the National Cancer Institute, noted there was no difference in risk of death when black patients received the same treatments, such as chemotherapy and surgery, as non-Hispanic white patients. "Other studies have looked at racial disparities in treatment and still others have focused on racial differences in survival rates of cancer patients, but our research attempted to go further by demonstrating the impact of race-based inequalities in cancer treatment on survival rates of black colorectal cancer patients," said James D. Murphy, MD, MS, assistant professor and chief of the Radiation Oncology Gastrointestinal Tumor Service at UC San Diego Moores Cancer Center. The researchers analyzed data from 11,216 patients over the age of 66 with stage IV colorectal cancer from the Surveillance, Epidemiology, and End Results (SEER)-Medicare database…

Chronic diseases hinder good cancer survival rates

How much diseases such as diabetes, COPD (chronic obstructive pulmonary disease), arthritis, depression and cardiovascular disease mean for cancer survival depends on the type of cancer; but the overall picture is the same. Other diseases have a strong negative impact on both the one and five-year survival rate. For example, for breast cancer the five-year survival rate for patients without other diseases is 83 percent. For patients with one or two other chronic diseases the survival rate is 64 percent, while it is 50 percent for those with three or more diseases. …

Hormones impact stress, memories, understanding social cues

Today’s new findings show that: Maternal stress can reduce levels of a chemical in the placenta that influences many other functions, such as development in mice. Additionally, the chemical could serve as a biomarker for maternal stress, a known risk factor for neurodevelopmental disorders like autism and schizophrenia Estrogen replacement therapy in post-menopausal women may help prevent stress-related memory loss Other recent findings discussed show that: Tamoxifen, a drug used to treat breast cancer, may protect against cognitive loss in post-menopausal women Estrogens, commonly thought of as a female reproductive hormone, are produced in the brains of males and females. …

Researchers discover new driver of breast cancer

The multidisciplinary team discovered that a cholesterol metabolite called 27-hydroxycholesterol, or 27HC, promotes tumor growth in estrogen-receptor positive breast cancers, which are the most common type of breast cancer. Estrogen-receptor positive breast cancer was previously believed to be stimulated primarily by the female sex hormone estrogen and it is commonly treated using endocrine-based medications that starve tumors of estrogen. The discovery of 27HC as another driver of breast cancer may explain why endocrine-based therapy is often unsuccessful, providing a new target for therapy, the researchers say. "This information can be used to develop new therapies that inhibit 27HC action or production, or increase its metabolism, in effect cutting the cancer off from a key growth stimulator," said senior author Dr…

Stem cell scarring aids recovery from spinal cord injury

Spinal cord injuries sever nerve fibres that conduct signals between the brain and the rest of the body, causing various degrees of paralysis depending on the site and extent of the injury. Functional impairment is often permanent, since the cut nerve fibres do not grow back. The lack of regeneration has been attributed to a blockage from scar tissue that forms at the lesion. …

Half of prostate cancer patients in NC do not receive multidisciplinary care

Working with local hospitals across North Carolina, UNC researchers led by Ronald Chen, MD, MPH, assistant professor of Radiation Oncology in the UNC School of Medicine, and Paul Godley, MD, PhD, Professor in the Division of Hematology/Oncology — both members of the UNC Lineberger Comprehensive Cancer Center — surveyed patients about their decision-making process after a prostate cancer diagnosis. "Prostate cancer is a unique disease where there are multiple treatment options, ranging from active surveillance to surgical treatments to radiation treatments…

Lower cancer screening rates, increased risk of preventable disease for South Asians in Ontario

The findings were published today in a report by researchers at the Centre for Research on Inner City Health. Peel Region — a municipality comprised of Brampton, Caledon and Mississauga, north of Toronto — has 1.3 million residents, nearly one-quarter of whom are of South Asian ethnicity…
