In 1998, an unusually large number of invasive lobular breast carcinoma cases were seen at the University of Washington. The purpose of this study was to assess whether the incidence rate of invasive lobular carcinoma has been increasing disproportionately compared with the incidence rate of invasive ductal carcinoma. ⋯ The incidence rates of invasive lobular breast carcinomas increased steadily since 1977 whereas the incidence rates of invasive ductal carcinoma have plateaued since 1987. This rise occurred specifically among women age >/= 50 years and may be related to postmenopausal status. Further epidemiologic, clinical, and laboratory research is required to assess what factors are contributing to this trend.

To the authors' knowledge there are few available data regarding the influence of lymphovascular space invasion, which has been examined separately as two components (lymphatic vessel invasion [LVI] and blood vessel invasion [BVI]), in the metastasis of cervical carcinoma. ⋯ Ovarian metastasis may occur via hematogenous spread of cervical carcinoma. The results of the current study suggest that BVI, including capillary vessels, that is diagnosed separately from LVI using hematoxylin and eosin stained sections may be an important prognostic factor for patients with cervical carcinoma.
