Excerpts from a 2003 study from the Breast Cancer Research site: http://breast-cancer-research.com/content/6/3/R149
From a total of 50,399 patients with early breast cancer in the Baylor College of Medicine Breast Cancer databases, we identified 4140 patients (8.2%) with ILC, and 45,169 (89.6%) patients with IDC (not otherwise specified). The median follow-up time was 87 months.
In comparison with IDC, ILC was significantly more likely to occur in older patients, to be larger in size, to be estrogen and progesterone receptor positive, to have lower S-phase fraction, to be diploid, and to be HER-2, and epidermal growth factor receptor negative.
ILC was three times more likely to metastasize to the peritoneum, gastrointestinal tract, and ovaries (6.7% versus 1.8%).
From this report it is evident that the metastatic pattern for ILC differs from that of IDC. ILC was less likely to affect the lungs, pleura, and CNS (Central Nervous System) than was IDC. By contrast, the peritoneum, ovary, and gastrointestinal system were much more likely to be involved in advanced ILC.
The 5-year disease-free survival was 85.7% for ILC and 83.5% for IDC (P = 0.13). The 5-year overall survival was 85.6% for ILC and 84.1% for IDC (P = 0.64).”
From another study in www.pubmed.gov:
“The 5- and 30-year corrected survival rates of women with ILC were 78% and 50%, respectively, compared with 63% and 37% for women with IDC.... We conclude that ILC is associated with better survival than IDC.”
BigWorrier, you also have to take into consideration the average survival rate for people in general, which includes falling down stairs, getting hit by cars, or choking on a nut!
