Objectives: Pleomorphic lobular carcinoma (PL) is an aggressive subtype of invasive lobular carcinoma. There are few case series reporting on this aggressive form of breast cancer. This report features a descriptive and survivorship comparison of a large case series of PL reviewed by a single breast pathologist. Methods: From 1993-2010 we retrospectively reviewed 198 cases of invasive lobular c...
PURPOSE To evaluate the relative effectiveness of letrozole compared with tamoxifen for patients with invasive ductal or lobular carcinoma. PATIENTS AND METHODS Patients diagnosed with early-stage invasive ductal carcinoma (IDC) or classic invasive lobular carcinoma (ILC) who were randomly assigned onto the Breast International Group (BIG) 1-98 trial and who had centrally reviewed pathology d...
CONTEXT Women using combined estrogen and progestin hormone replacement therapy (CHRT) have an increased risk of breast cancer; however, data on use for long durations and on risk associated with patterns of use are lacking. OBJECTIVE To evaluate relationships between durations and patterns of CHRT use and risk of breast cancer by histological type and hormone receptor status. DESIGN Popula...
BACKGROUND The frequency of migraine headache changes at various times of a woman's reproductive cycle. Menarche, menses, pregnancy, and perimenopause may carry a different migraine risk conceivably because of fluctuating estrogen levels, and in general, migraine frequency is associated with falling estrogen levels. Given the strong relationship between endogenous estrogen levels and breast can...
Invasive lobular carcinoma (ILC) of the breast, characterized by loss of E-cadherin expression, accounts for 5-15% of invasive breast cancers and it is believed to arise via a linear histological progression. Genomic studies have identified a clonal relationship between ILC and concurrent lobular carcinoma in situ (LCIS) lesions, suggesting that LCIS may be a precursor lesion. It has been shown...
