New treatment designed to save more eyes from cancer

Treatments for retinoblastoma have progressed dramatically in recent years, one being a procedure called ophthalmic artery infusion chemotherapy. A tiny catheter is inserted into an artery that provides blood flow (and chemotherapy) directly to the eye and tumor. Originally introduced in the late 1980s, direct ophthalmic artery infusion significantly increases treatment effectiveness while reducing side effects. Unfortunately, many children with retinoblastoma are not good candidates for conventional ophthalmic artery infusion — in particular younger, smaller patients with advanced disease, according to Todd Abruzzo, MD, director of Interventional Neuroradiology at Cincinnati Children’s. …

Fertility preservation option for young boys with cancer

The research, conducted by the Medical Center’s Wake Forest Institute for Regenerative Medicine (WFIRM) under the direction of Anthony Atala, M.D., institute director, gives boys who have a high risk of becoming sterile the option to “bank” a small piece of testicular tissue prior to treatment. “The average survival rates for childhood cancer are around 80 percent, but a side effect of some treatments can be permanent sterility,” said Thomas W. McLean, M.D., a pediatric cancer specialist, who co-leads the experimental biological bank with Hooman Sadri-Ardekani, M.D., Ph.D., a male infertility specialist at WFIRM. …

Newer tests clarify hereditary risk of cancer

“There is this group of people who think they don’t need to worry about getting cancer and believe they don’t have a high family risk of getting cancer, but unfortunately do,” said Mahon, a professor in internal medicine at Saint Louis University. Mahon says her requests for genetic testing for breast cancer have more than tripled since 2013, when actress Angelina Jolie announced she had a double mastectomy because she was at genetic risk of developing breast cancer…

Improved risk identification will aid fertility preservation in young male cancer patients

By clarifying which patients are at highest risk for reduced sperm production as adults, researchers expect the findings to eventually increase use of pre-treatment fertility preservation methods such as sperm banking. The study involved drugs called alkylating agents that are widely used to treat a variety of pediatric cancers. …

Re-expression of an embryonic signaling pathway in Melanoma utilizes different receptors

During early vertebrate development, Nodal, an embryonic growth factor that governs the growth, pattern and position of tissues, is critical for normal maturation. Nodal plays a significant role in maintaining the pluripotency of embryonic stem cells, meaning the ability of stem cells to differentiate into any of the three germ layers that comprise the body. The recent discovery of Nodal’s re-expression in several aggressive and metastatic cancers has highlighted its critical role in self-renewal and maintenance of the stem cell-like characteristics of tumor cells such as melanoma. However, the signaling pathway receptors utilized by melanoma cells to propagate Nodal’s effect remain(s) mostly anecdotal and unexplored…

Study identifies gene network behind untreatable leukemia, possible treatment target

Scientists from the Cancer and Blood Diseases Institute (CBDI) at Cincinnati Children’s Hospital Medical Center report their results in a study posted online Sept. 4 by Cell Reports. The specific forms of AML and MDS in the current study involve deletions on the arm of a specific chromosome in blood cells (del(5q)…

New estrogen-based compound suppresses binge-like eating behavior in female mice

“Previous data has shown that women who have irregular menstrual cycles tend to be more likely to binge eat, suggesting that hormones in women play a significant role in the development or prevention of the behavior,” said Dr. Yong Xu, assistant professor of pediatrics and senior author of the paper. “Previous data has also shown that in humans, there is a strong association between estrogen and binge eating. …

Natural killer cells battle pediatric leukemia

Acute lymphoblastic leukemia (ALL) is the most common cancer of childhood. This disease hinders the development of healthy blood cells while cancer cells proliferate. Currently, children with ALL receive chemotherapy for two to three years, exposing them to significant side effects including changes in normal development and future fertility. As a way to avoid these adverse effects, investigators have been researching how to supercharge the body’s innate cancer-fighting ability — a technique called immunotherapy…

Guidelines can predict early menopause in child cancer survivors, giving hope for fertility

The criteria — developed in Edinburgh — will help to select which girls should be offered the opportunity to freeze some tissue from their ovaries for use in the future. Doctors are optimistic that the frozen tissue could one day help young cancer survivors to have children of their own…
