Black breast cancer patients less likely to benefit from chemo before surgery

CANCER DIGEST – Dec. 1, 2015 – Among minority women treated with early chemotherapy, black women have worse outcomes than the other groups, a Yale Cancer Center analysis of the National Cancer Database shows.  

Black, Hispanic, and Asian women typically develop advanced-stage breast cancer more often than white women. As a result, black women are more likely to receive chemotherapy prior to surgery, or neoadjuvant chemotherapy, to reduce the tumor volume before the surgeon attempts to remove it in hopes of improving outcomes.

Girl undergoes first-ever ‘gene-editing’ treatment

Layla, shown here at 16 months,
is the first patient to receive new
treatment 
CANCER DIGEST – Nov. 7, 2015 – A one-year-old girl in London, England with leukemia is now cancer free and doing well as a result of a new treatment that uses ‘molecular scissors’ to edit genes and create designer immune cells.

The girl, named Layla, had relapsed acute lymphoblastic leukemia (ALL) that had failed to respond to conventional therapies and had limited treatment options available.

The patient’s parents were keen to try the treatment. Mother, Lisa, says: "We didn’t want to accept palliative care and so we asked the doctors to try anything for our daughter, even if it hadn’t been tried before."

Antioxidants may boost cancer spread


CANCER DIGEST ­– Oct. 19, 2015 - A team of scientists at the Children’s Research Institute at UT Southwestern (CRI) has made a discovery that suggests cancer cells benefit more from antioxidants than normal cells, raising concerns about the use of dietary antioxidants by cancer patients. 
The study done in mice suggests a mechanism that may explain why cancer patients have often had worse outcomes in clinical trials involving giving antioxidants to these patients.
Dr. Sean Morrison, director of pediatric genetics, UT

 “The idea that antioxidants are good for you and has been so strong that there have been clinical trials done in which cancer patients were administered antioxidants,” Dr. Sean Morrison director of pediatric genetics at University of Texas Southwestern Medical Center said in a press release. “Some of those trials had to be stopped because the patients getting the antioxidants were dying faster. Our data suggest the reason for this: cancer cells benefit more from antioxidants than normal cells do.”

More peace, no increased pain for cancer patients who die at home

CANCER DIGEST – Oct. 12, 2015 – Dying at home could be beneficial for terminally ill cancer patients and their relatives, according to a study published online in the journal BMC Medicine.

The study shows that, according to questionnaires completed by their relatives, those who die at home experience more peace and a similar amount of pain compared to those who die in a hospital, and their relatives also experience less grief. However, this requires discussion of preferences, access to a comprehensive home care package and facilitation of family caregiving.

Pancreatic cancer stem cells could be 'suffocated' by diabetes drug


CANCER DIGEST – Sept. 21, 2015 – A new study shows that pancreatic cancer stem cells (PancSCs) are virtually addicted to oxygen–based metabolism, and could be “suffocated” with a drug already used to treat diabetes. 

Cancer cells commonly rely on glycolysis, a type of metabolism that does not use molecular oxygen to generate energy. PancSCs can make use of an even more efficient form of metabolism, called oxidative phosphorylation or OXPHOS, which occurs in a part of the cell called mitochondria. Metformin blocks PancSCs from using OXPHOS triggering cell death, or apoptosis.

Shapeshifting marker for cancer cells identified


CANCER DIGEST – Aug. 10, 2015 – In a first of its kind study researchers have identified a genetic biomarker responsible for the progression of many breast and prostate cancers. 

The newly identified biomarker is called diaphanous-related formin-3 or DIAPH3, which participates in a protein interaction that makes cells rigid. The study found that when this biomarker is lost or decreased, cells become flexible or pliable allowing them to squeeze through tissue spaces. Cancer cells with this property can invade normal tissues and adhere to other tissues in the body.

Study shows dramatic shift to prostate cancer treatments that match risk


CANCER DIGEST – July 27, 2015 – In the first study to document updated treatment trends, researchers found that from 2010 to 2013, 40 percent of men with low-risk prostate cancer opted for active surveillance, in which the disease is monitored closely with blood tests, imaging studies and biopsies. Treatment is deferred unless these tests show evidence of progression.

That is much higher than the 10 percent of low-risk prostate cancer patients who pursued active surveillance in the years from 1990 through 2009. Rates for radiation therapy for this low-risk group have also slipped since 1995. The analysis was based on an ongoing study called, Cancer of the Prostate Strategic Urologic Research Endeavor or CaPSURE Registry. The study published in the July 7, 2015 JAMA.

Study shows dramatic shift in prostate cancer treatment

CANCER DIGEST – July 8, 2015 – A new analysis of national prostate cancer treatment trends shows that there has been a big shift away from aggressive treatment to watchful waiting and active surveillance for men diagnosed with prostate cancer since the early 1990s.

Watchful waiting avoids aggressive testing and watches for any physical symptoms of progressive disease. It is generally reserved for avoiding treatment altogether for older, sicker patients who will most likely die from something else. Active surveillance uses repeated PSA testing and prostate biopsies to monitor for development of more aggressive disease in younger, healthier patients who might benefit from delaying treatment.

New blood test can predict future breast cancer

CANCER DIGEST – April 17, 2015 – It sounds like something out of Dr. McCoy’s physician’s bag on Star Trek, a simple test that can tell whether a patient would likely develop cancer within the next five years, but that’s what Dutch scientists say they have developed.

By analysing a simple blood sample, scientists from the University of Copenhagen have succeeded in predicting if a woman will get breast cancer within two to five years. The method – a metabolic blood profile – is still in the early stages but over time the scientists expect it could be used to predict breast cancer and more generally to predict chronic disease.

Circulating tumor DNA can be used to tailor treatment

Men’s midlife fitness linked to lower risk of cancer and death

CANCER DIGEST – Mar. 26, 2015 – Men who exercise and stay fit, especially in midlife, could be lowering their risk of lung cancer and colorectal cancer, but not prostate cancer, researchers say. Before you say two out of three isn’t bad, there's better news. While fitness didn’t protect against getting prostate cancer, fit men appear to be less likely to die of the disease.

Led by Dr. Susan Lakoski of the University of Vermont, Burlington, the researchers looked at Medicare data from 1999 to 2009 for a link between midlife cardiorespiratory fitness and cancer and survival following a cancer diagnosis at the Medicare age of 65 or older.

Very low breast density linked with lower survival in women with breast cancer

CANCER DIGEST – March 13, 2015 – Women with breast cancer whose breasts have very low density have a higher risk of dying from the disease than women with high breast density, a new Finnish study shows.

Dense breast tissue has long been linked to an increased risk of breast cancer, and it is difficult to detect small tumors when screening dense breasts. This results in a higher occurrence of clinically detectable cancers. Breast density is matter of the amount of glandular tissue present compared to fat tissue.
