Objective: To identify perioperative variables associated with length of stay in the surgical intensive care unit (SICU), and overall cost of hospitalization in order to optimize resource utilization among patients undergoing surgery for ovarian cancer.
Methods: A retrospective analysis of patients admitted to the SICU immediately after surgery for ovarian cancer between 1/1/94 and 6/30/04 was performed. Patients admitted to the SICU were categorized in two groups.
Objectives: To characterize the primary surgical care and short-term outcomes for uterine cancer in women age > or = 80 years compared to younger women.
Methods: A statewide hospital discharge database was used to identify women that underwent primary surgery for uterine cancer from 1994 to 2005. Logistic regression models were used to evaluate for significant differences in demographic characteristics and short-term outcomes comparing women aged > or = 80 years with those aged < 80 years.
Objective: To evaluate the clinico-pathologic characteristics and survival outcome associated with overexpression of Her-2/neu in patients with uterine serous carcinoma (USC).
Methods: Twenty-five patients with a confirmed pathologic diagnosis of USC and available paraffin embedded tissue samples treated at the Johns Hopkins Medical Institutions from 1/1/1992 through 12/31/2000 were identified retrospectively. Her-2/neu expression was evaluated by immunohistochemistry using HercepTest (DAKO).
Objective: To characterize the primary surgical care and short-term outcomes for ovarian cancer in women aged 80 years and older compared to women younger than 80 years.
Methods: A statewide hospital discharge database was used to identify women undergoing primary surgery for ovarian cancer from 1990 to 2000. Logistic regression models were used to evaluate for significant differences in demographic characteristics and short-term outcomes comparing women aged > or = 80 years with those aged <80 years.
Objectives: The goals of this study were to: (1) characterize the etiology of abdominal carcinomatosis, (2) identify clinical features predictive of primary ovarian/peritoneal cancer, and (3) evaluate the survival impact of cytoreductive surgery among patients with advanced ovarian/peritoneal cancer and a history of breast cancer.
Methods: Patients with a history of prior breast cancer undergoing surgical exploration for abdominal carcinomatosis between 1/1/88 and 12/31/02 were retrospectively identified from tumor registry databases. Logistic regression analysis was used to explore clinical characteristics predictive of primary ovarian/peritoneal cancer versus recurrent breast cancer.
Objectives: To evaluate the demographic characteristics, clinico-pathological features, and patterns of care of uterine cancer among Hispanic women living in the United States.
Methods: The National Cancer Institute (NCI)'s Surveillance, Epidemiology, and End Results Program (SEER), was used to identify 1618 Hispanic, 17,814 non-Hispanic white (NHW), and 1477 non-Hispanic black (NHB) women diagnosed with primary carcinoma of the uterus during 1996-2000. Data derived from hospital registries was analyzed, for differences in case presentation, staging, and primary treatment by race/ethnicity and age.
Purpose: To characterize the patterns of primary surgical care for ovarian cancer in a statewide population according to annual surgeon and hospital case volume.
Methods: The Maryland hospital discharge database was accessed for annual surgeon and hospital ovarian cancer case volume for the time intervals: 1990-1992, 1993-1995, 1996-98, and 1999-2000. Annual surgeon case volume was categorized as low (/=10).
Objective: The aim of this study was to evaluate the utility of combined positron emission tomography/computed tomography (PET/CT) for identifying ovarian cancer tumor masses > or =1 cm in patients with clinically occult recurrent disease by conventional CT imaging.
Methods: Twenty-two patients with epithelial ovarian cancer, rising serum CA125 levels, and negative or equivocal conventional CT imaging > or =6 months after primary therapy underwent combined PET/CT imaging followed by surgical reassessment. Fisher's exact test was used to measure the ability of PET/CT to predict macroscopic disease > or =1 cm.
Background: The objectives of the current study were to: 1) characterize the clinical outcome of patients with recurrent micropapillary serous ovarian carcinoma (MPSC) and 2) evaluate the survival impact of secondary cytoreductive surgery and other prognostic variables.
Methods: Twenty-six patients with recurrent MPSC were identified retrospectively from hospital and tumor registry databases. Survival curves were generated from the time of tumor recurrence using the Kaplan-Meier method and statistical comparisons were performed using the log-rank test, logistic regression analysis, and the Cox proportional hazards regression model.
Objectives: The objectives of this study were to characterize the prognostic features of micropapillary serous ovarian carcinoma (MPSC), examine the clinical impact of surgical staging, and define the role of cytoreductive surgery for patients with advanced disease.
Methods: Fifty-one patients with MPSC were identified from hospital and tumor registry databases. Demographic, operative, pathologic, and follow-up data were abstracted retrospectively.
