A simple test may catch early pancreatic cancer

The findings of their research, if confirmed, they say, could be an important step in reducing mortality from the cancer, which has an overall five-year survival rate of less than 5 percent and has seen few improvements in survival over the last three decades. "We have mammograms to screen for breast cancer and colonoscopies for colon cancer but we have had nothing to help us screen for pancreatic cancer," says Nita Ahuja, M.D., an associate professor of surgery, oncology and urology at the Johns Hopkins University School of Medicine and leader of the study described online this month in the journal Clinical Cancer Research. …

Imaging breast cancer with light

If effective, the new device, called a photoacoustic mammoscope, would represent an entirely new way of imaging the breast and detecting cancer. Instead of X-rays, which are used in traditional mammography, the photoacoustic breast mammoscope uses a combination of infrared light and ultrasound to create a 3-D map of the breast…

Tailored doses of cytostatic improve survival rate after stem cell transplantation

The results, which are presented in the scientific journal The Lancet, are based on a clinical study conducted at 16 hospitals around the world. Chronic granulomatous disease (CGD) is a rare immune deficiency in children that causes recurrent, often difficult-to-treat bacterial and fungal infections and non-bacterial inflammations of the inner organs, which sometimes develop into tumour-like nodules of inflammatory tissue known as granuloma. …

Chronic pain in dogs with bone cancer relieved with new treatment

"Dogs are part of the family and we do everything we can to relieve them of pain and discomfort when they are sick," said Dorothy Cimino Brown, D.V.M., School of Veterinary Medicine, University of Pennsylvania, Philadelphia. "In addition to sharing emotional attachments with our dogs, humans share many of the same ailments our pets suffer when fighting cancer. By studying the positive pain relief this treatment afforded dogs, we are hopeful it may also be effective for humans." The evolution of bone cancer pain in dogs parallels what occurs in humans, with the frequency and intensity of pain increasing over weeks and months. As the cancer advances, both canine and human patients experience life-altering pain, which greatly affects their daily activities and quality of life. …

Screening guidelines may miss ten percent of colon cancers

In the largest population-based study to date, researchers from Huntsman Cancer Institute (HCI) at the University of Utah made this finding based on nearly 127,000 individuals who underwent colonoscopy in Utah between 1995 and 2009. The results appear online in “Early View” of the journal Cancer. Family history of colon cancer is widely accepted as a factor that increases risk for the disease. …

New program makes prostate cancer treatment decisions easier

A recent clinical study published in the New England Journal of Medicine showed that mortality rates for early stage prostate cancer were the same for men who choose active surveillance such as periodic PSA testing and biopsy, versus those who chose to treat their disease immediately with radiation or surgery. The research suggested that in cases of low-risk prostate cancer, aggressive treatment may not offer a long term survival benefit, and yet is associated with a number of side effects such as urinary incontinence and sexual problems. However, the vast majority of men diagnosed with low-risk cancer undergo aggressive treatment rather than active surveillance…

‘Phenotype switching’ can make melanoma become metastatic, resistant to drugs

The findings were published in the journal Cancer Discovery and are currently available online. "We were able to demonstrate for the first time that different receptors within a single signaling pathway — in this case, the Wnt signaling pathway — can guide the phenotypic plasticity of tumor cells, and increased signaling of Wnt5A in particular can result in an increase in highly invasive tumor cells that are less sensitive to existing treatments for metastatic melanoma," said Ashani Weeraratna, Ph.D., assistant professor in the Tumor Microenvironment and Metastasis Program of Wistar’s NCI-designated Cancer Center, and senior corresponding author on the manuscript. …

Suffering from breast cancer increases the risk of another tumour by 39%

A national team of researchers has analysed the risk that women diagnosed with a first case of invasive breast cancer face of developing a second primary cancer in a part of the body other than the breast. The results, published in the journal Gynecologic Oncology, indicate that this risk is 39% higher. María José Sánchez, co-author of the study and director of the Granada Cancer Register explained to SINC that the team’s study is the first populational study ever conducted in Spain to examine this associated risk. According to the study’s data, women under the age of 50 who had previously suffered from breast cancer were almost twice as likely to develop a second cancer than the general population (the risk was 96% greater). …
