Prior cancers common in patients newly diagnosed with cancer

A new study conducted at the University of Texas Southwestern Medical Center in Dallas indicates that between 2009 and 2013, nearly 20% of patients newly diagnosed with cancer had a previous history of cancer diagnosis.  According to lead author Dr. Caitlyn Murphy, "some types of second primary cancer - such as leukemia - can be related to chemotherapy or radiation therapy used to treat a prior cancer", necessitating that clinicians be aware of these possible links when caring for cancer survivors.

Gum disease tied to esophageal cancer

A new study conducted at NYU Langone Health in New York City has drawn a correlation between gun disease bacteria and the risk of developing esophageal cancer.  The study, conducted on 122,000 Americans who's oral health was observed over a period of 10 years found that "the presence of one oral bacterium in particular, Tannerella forsythia...led to a 21% increase in the odds of developing esophageal tumors."  This find noted emphasized the importance of regularly brushing, flossing, and dental visits.

Low-fat diet may reduce pancreatic cancer risk for older overweight women

A new study conducted at the Baylor College of Medicine in Houston, Texas suggests that a low-fat diet may reduce risk of pancreatic cancer among women between 50-79 that are overweight or obese. According to the study's first author, Dr. Li Jiao, 46,000 overweight and obese women were part of a clinical trial held between 1993-1998.  After 15 years of follow-up, 92 cases of pancreatic cancer occurred following a low-fat diet, compared to 165 cases in the comparison group.

Blood thinner may lower cancer risk

New research being conducted at the University of Bergen in Norway indicates that Warfarin, a commonly prescribed blood thinner may lower the risk of developing cancer.  While lead researcher James Lorens cautioned that the observational study, conducted on 1.25 million Norwegian people aged 50 and older, does not "prove a cause and effect relationship...[that] warfarin reduced the risk of cancer", cancer models have determined that warfarin blocks the AXL receptor on tumor cells.

Should colon cancer screening began at an earlier age?

A new French study from the Clinique de Bercy in Charenton-le-Pont, has proposed that earlier screening (i.e. at age 45 instead of age 50) be undertaken for colon cancer.  The study, conducted on 6,000 patients who had a colonoscopy, determined that "among 45-49 year-old patients, 26% showed growth called adenomas...compared to 13% of patients ages 40 to 44."  Lead researcher Dr. David Karsenti, who presented the findings at the October 30th United European Gastroenterology Meeting in Barcelona, Spain feels that delaying screening until age 50 could limit some patients' odds of surviving a colon cancer diagnosis.

Gene therapy may prevent brain cancer recurrence

 A new phase I clinical trial conducted at the University of Minnesota Medical School  indicates that gene therapy treatment may prevent the recurrence of brain cancer cancer.  The trial, conducted on 56 patients with recurrent high-grade glioma brain cancer shows that "3 years after the gene therapy treatment, more than a quarter of the patients were still alive."  Median survival time for patients was raised to 14.4 months, compared to 8 months for patients without the gene therapy.

How breast cancer gene mutations raise risk of tumours

Researchers at the Yale Cancer Center claim to have identified the molecular mechanism that enables the mutation to cause the BRCA1 gene to lose its DNA repair and tumour-fighting power" and thus trigger breast cancer.  According to Patrick Sung, study senior author, results from these findings could lead to more effective drugs to treat breast and ovarian cancers.

Expert panel supports HPV test alone for cervical cancer screening over 30

The U.S. Preventive Services Task Force (USPSTF), a panel of health experts, is supporting use of the HPV test as a routine component for cervical cancer screening.  The panel recommends that "the test for the human papillomavirus (HPV) can be used once every five years for women aged 30 to 65, in lieu of the once every three-year Pap test."  For women younger than 30, aged 21-29, undergoing a Pap test once every 3 years remains the recommended option.

New research on how fat cells encourage tumours and raise cancer risk

New research conducted at the Huntsman Cancer Institute in Salt Lake City indicates that "16 different types of cancer [are] linked to obesity."  In a new review, published today (September 5, 2017) in Cancer Prevention Research, data from 20 studies, published over the past 70 years, focused on adipose stromal cells (fat cells) and their association with malignant tumours.  The findings indicated that "obese people with prostate or breast cancer appeared to have more [adipose stromal] cells than thinner people."

New trial alert: Management of malignant bowel obstruction (MBO) in patients with advanced gynecological cancers

A new trial, conducted at the Princess Margaret Cancer Centre in Toronto is seeking to optimize multidisciplinary care and evaluate treatment outcomes for malignant bowel obstruction (MBO) in women with advanced gynecological cancers.  According to the trial's hypothesis, "if patients with MBO can be effectively managed in an ambulatory setting, this may improve quality and consistency of patient care, and help reduce volume and duration of bed occupancy."

Common treatment for early prostate cancer may carry heart risk

A new study conducted on 7,600 men with early stage prostate cancer suggests that androgen-deprivation therapy may increase the risk for heart failure.  According to study author Reina Haque, a researcher with Kaiser Permanente, "patients should consider heart-healthy lifestyle changes, and physicians should actively monitor the patient's health for early signs of heart disease."  Dr. Nachum Katlowitz, director of urology at Staten Island University Teaching Hospital in New York City agrees with Haque; his reasoning is that all treatments carry potential side effects, however "if androgen-deprivation therapy increases the risk of dying from cardiovascular disease, but decreases the risk of dying from prostate cancer, then we use it."

Study supports annual mammograms starting at age 40

A new study conducted at the University of Colorado School of Medicine supports guidelines suggesting that annual mammograms begin at age 40.  According to study co-author R. Edward Hendrick, computer modeling was conducted by his team of investigators on mammogram recommendations for three age groups: annual screening from ages 40-84, annual screening from ages 45-54; every other year from 45-54, and screening every other year from 50-74.  According to projections, "deaths from breast cancer would fall by an average of 40% with annual screenings" from ages 40-84.

DNA blood test screen for rare sinus cancer

Researchers at the Li Ka Shing Institute of Health Sciences in Hong Kong have discovered that at DNA blood test can screen for nasopharyngeal cancer.  While this form of cancer is rare in the United States (with an occurrence of 1 case in every 100,000 people), it is far more common in southern China and North Africa.  Following a clinical trial conducted on more than 20,000 individuals, "the DNA test would up accurately detecting nasopharyngeal cancer 97% of the time."
