Removing the aortic and pelvic lymph nodes during surgery for advanced ovarian cancer improves progression-free survival but not overall survival, according to a new study in the April 20 issue of the Journal of the National Cancer Institute.
Ovarian cancer is the fifth most common cancer in women worldwide. In the United States, about 25,000 women were diagnosed with the disease in 2004 and 16,000 women died from it. Long-term survival is possible after surgery and chemotherapy, but only about 30% of patients with advanced ovarian cancer survive 5 or more years after diagnosis. Retrospective studies have suggested that lymphadenectomy--the removal of the aortic and pelvic lymph nodes during cytoreductive surgery to remove the cancer--may improve survival, but the value of the procedure remains controversial.
To determine whether systematic aortic and pelvic lymphadenectomy improves progression-free and overall survival, Pierluigi Benedetti Panici, M.D., of "La Sapienza" University in Rome, and colleagues conducted a clinical trial in which 427 patients with advanced ovarian cancer were randomly assigned to undergo either primary cytoreductive surgery followed by lymphadenectomy or cytoreductive surgery only. The patients were followed for an average of 68.4 months.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
