A new study finds chemotherapy improves survival and reduces the risk of recurrence in women with stage I ovarian cancer (cancer that has not spread beyond the ovary). But it remains unclear which patients would most benefit from adjuvant chemotherapy and what the optimal treatment regimen would entail. The findings come from an analytical review of data from 13 randomized control trials (RCTs), which will be published in the November 1, 2004 issue of CANCER, a peer-reviewed journal of the American Cancer Society. A free abstract of this article will be available via the CANCER News Room upon online publication.
About one quarter of all ovarian cancers are caught while confined to the ovaries, when five-year survival is 85 percent. But the therapeutic benefit of adjuvant chemotherapy remains controversial. All physicians agree that surgery that includes staging is critical to survival. Some doctors may prefer not to offer chemotherapy for their patients, since eight in ten are adequately treated by surgery alone. They could argue that giving all stage I patients chemotherapy would lead to unnecessary adverse events with no survival benefit for the majority of patients.
Given the controversy, Laurie Elit, M.D., of the Juravinski Regional Cancer Centre in Ontario, Canada and her colleagues conducted a meta-analysis of RCT data published since 1965.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
