Objective: To investigate the incidence, clinicopathological characteristics and survival of ocular adnexal lymphoma (OAL) in the paediatric population.

Methods And Analysis: In this retrospective case series, the Surveillance, Epidemiology and End Results database was accessed to identify individuals with OAL ≤18 years of age, diagnosed between 1973 and 2015. OAL located in the eyelid, conjunctiva, lacrimal apparatus and orbit were included.

Objective: To determine whether there is an increased risk of ovarian cancer in women undergoing radical cystectomy (RC) for bladder cancer using a large population-based data source. Current American Urologic Association guidelines suggest removal of ovaries during RC in women with bladder cancer, presumably to mitigate the risk ovarian cancer. However, recent data have demonstrated an increased risk of all-cause mortality, cardiovascular disease, osteoporosis, cognitive impairment, and diminished sexual function in some populations of women after oophorectomy.

Background: Breast carcinomas in African-American patients appear to be more aggressive than in Caucasian patients due to multifactorial differences.

Methods: The authors compiled pathology data from the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) database regarding stage, histologic grade, and estrogen receptor (ER) expression in breast carcinomas diagnosed in 197,274 African-American and Caucasian patients between 1990 and 2000, and the same information, along with nuclear grade, Ki-67, c-erb-B2, and p53 expression, in 2230 African-American and Caucasian patients diagnosed at Thomas Jefferson University Hospital between 1995 and 2002. Immunohistochemical markers were assayed in paraffin-embedded, formalin-fixed tissue stained with hematoxylin and eosin using antibodies to these proteins, with differences in expression analyzed by the chisquare test.

Purpose: The purpose of this study was to evaluate the prognostic significance of positive microscopic margins in hilar cholangiocarcinoma in patients treated with resection and adjuvant radiotherapy.

Materials And Methods: Between January 1983 and December 1997, 65 patients were definitively diagnosed with hilar cholangiocarcinoma and treated at our institution. Twenty-eight patients underwent curative resection.

The purpose of this study was to evaluate how the outcome of patients with extrahepatic cholangiocarcinoma (EHBC) may have been influenced by tumor location and treatment selection. The primary endpoint of this study is overall survival (OS). Between January 1983 and December 1997, 221 patients with biliary tumors were evaluated at Thomas Jefferson University Hospital.
