Children treated for soft tissue sarcomas have a significantly higher risk of developing subsequent cancers later in life, according to a new study. The study appears in the June 1, 2005 issue of CANCER (http://www.interscience.wiley.com/cancer-newsroom), a peer-reviewed journal of the American Cancer Society, and indicates children treated with combined chemotherapy and radiation therapy, in particular, had greater risks of developing a new malignancy.
With improvements in cancer treatments over the last two decades, children with soft tissue sarcomas are living longer. Several investigations have reported that these children have an increased risk of second cancer, but estimates of the risk have varied widely, ranging from three to thirteen times the risk among the general population. Moreover, due to the small size of many previous studies, few have evaluated risk by type of soft tissue sarcoma or have estimated risks for specific second cancers.
Randi J. Cohen, M.S. and a team of researchers from the National Cancer Institute (NCI) evaluated data from 1499 children included in one of the largest, most comprehensive cancer databases in the U.S., called the Surveillance, Epidemiology, and End Results (SEER) Program of the National Cancer Institute. Their goal was to quantify the risk of developing a second malignancy in soft tissue sarcoma patients by second cancer site, initial therapy, histologic type of the primary sarcoma, age at primary cancer diagnosis, and gender.

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
