The Princess Margaret Hospital study of ovarian cancer: stages I, II, and asymptomatic III presentations

Cancer Treatment Reports
A J DemboJ F Sturgeon


An analysis of 231 patients with stages I, II, and asymptomatic III ovarian cancer, studied in a prospective randomized-stratified trial, is presented. None of the stage IA patients with well-differentiated tumors have had disease relapses; one fourth of the patients with poorly differentiated tumors have had disease relapses throughout the peritoneal cavity. There is therefore little justification for pelvic radiation alone as postoperative therapy for stage IA ovarian carcinoma. For stage IB, II, and asymptomatic III presentations, patients with an incomplete initial pelvic operation had poor survival characteristics with all tested therapies. For patients in whom the operation was completed, abdominopelvic radiation was superior to pelvic radiation alone or followed by chlorambucil, with respect to long-term survival and control of abdominal disease. The effectiveness of abdominopelvic radiation was independent of stage or histology. The value of abdominopelvic radiation was most strikingly seen in patients with no visible residual tumor.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Cell Atlas Along the Gut-Brain Axis

Profiling cells along the gut-brain axis at the single cell level will provide unique information for each cell type, a three-dimensional map of how cell types work together to form tissues, and insights into how changes in the map underlie health and disease of the GI system and its crosstalk with the brain.
