Late neointimal tissue growth behind the stent after intravascular gamma-radiation.
2003
To determine the nature of the changes of the vascular wall after intravascular brachytherapy in stented arteries leading to incomplete stent apposition.Stents were implanted in the infrarenal aortas of rabbits, and gamma-intravascular brachytherapy (18 Gy) or a sham radiation procedure was immediately implemented. The arteries were harvested at 6 months for histologic analyses.The external elastic lamina area, as well as the vascular wall area behind the stent, were significantly greater in irradiated vs. control arteries (8.94 +/- 0.68 mm2 vs. 6.87 +/- 0.40 mm2 [p0.001] and 1.56 +/- 0.13 mm2 vs. 0.72 +/- 0.07 mm2 [p0.001], respectively). The ratio of the intimal area behind the stent rela…
Prognostic Factors of Survival among Women with Metastatic Breast Cancer and Impact of Primary or Secondary Nature of Disease on Survival: A French P…
2016
We aim to determine whether differences in survival exist between two populations of women with metastatic breast cancer (MBC) and to identify prognostic factors of survival after metastasis diagnosis. Data on women with MBC diagnosed between 2000 and 2011 were provided by the Cote d'Or Breast cancer registry. Survival rates and median overall survival (OS) after metastasis diagnosis were determined using the Kaplan–Meier method and prognostic factors were determined in a Cox proportional hazard model. Overall, 282 women with primary MBC and 340 with secondary MBC were included. A 2-year survival rate was significantly better in women with primary MBC (50.8% [95% CI: 47.8–53.8%] versus 44.5…
