Detailed analysis regarding breast cancer times claimed. an excellent Many years shipment of the frequency of breast cancer identified from inside the 181 NF1 customers than the SEER databases claimed breast cancer many years distribution out of incident circumstances. b Distribution off breast cancer stage in the lifetime of diagnosis of cancer of the breast recognized inside the 54 NF1 customers. c Ages distribution of your incidence away from cancer of the breast dying known in the 76 NF1 clients as compared to SEER database reported breast cancer age distribution out of deaths

So it occurrence from cancer of the breast cases is actually versus SEER databases for advertised cancer of the breast age shipping off incident times, and that displayed a peak ages of medical diagnosis amongst the age of 55 so you’re able to 64 age on https://datingranking.net/nl/luvfree-overzicht/ general inhabitants (Fig

This incidence of breast cancer deaths was compared to the SEER database for reported breast cancer age distribution of deaths, demonstrating a peak age of death between the ages of 55 to 64 years in the general population (Fig. 2c). The relative survival of the female NF1 patients with breast cancer identified in this study was compared to the general population using the SEER database controlling for age and year at diagnosis for each patient (Fig. 3). The median survival for this entire NF1 breast cancer cohort was 5 years compared to the reported median breast cancer survival of over 20 years in the general population using the SEER database. When separated by age, the median survival of the female NF1 patients with breast cancer identified in this study was 5.58 years in those < 50 years of age and over 15 years in those ?50 years of age.
