Sample size and recruitment procedure:
The investigators will select a cohort of patients with positive PSA results and a cohort of patients with negative results in each centre, to be followed for two years.
According to a review by the American Cancer Society, a value of PSA of 4 ng/ml had an
We will review medical records to identify patients who underwent percutaneous needle biopsy of a lung mass between 5/1/01 and 10/30/04. If the pathology report indicates that the biopsy showed no evidence of malignancy, we will examine the medical record for a "gold standard" diagnosis of the
The purpose of this study is to conduct clinical research to investigate the association of the gut microbiome with colonic neoplasia. In this case several types of gut microbiome samples will be collected from patients undergoing colectomy for colonic adenocarcinoma; those samples will be tested by
PRIMARY OBJECTIVES:
I. To assess whether premedication with a corticosteroid may reduce false positive findings on fluorodeoxyglucose (fludeoxyglucose F 18 [FDG[) PET/computed tomography (CT) scans in lung cancer patients, by reducing radiotracer uptake in thoracic lymph nodes related to
The investigators expect to show in a prospective clinical trial that, in women with a personal history of breast cancer, contrast-enhanced mammography substantially improves breast cancer detection compared to mammography with tomosynthesis, with minimal increase in false positives. The
The main object of the study is to evaluate, whether sentinel lymph node biopsy (SLNB) at women with breast cancer after neoadjuvant therapy is a method with a high false-negative rate. Patients will be classified into groups according to histological findings during SLNB, clinical and
The general objective for this study is to evaluate the survival and disease-free period of women participating in screening programs for breast cancer with a cancer diagnosed during the screening or an interval cancer, specifically true interval cancers and false negatives.
The cohort has
Women from every Kentucky county participate in the Kentucky Ovarian Cancer Screening Program. Screening sites include: Maysville, Prestonsburg, Greenup, Elizabethtown, Somerset, Paducah and Lexington. Offsite participants account for 14% of the screening population with 86% being screened in
The trial is a parallel randomized controlled trial comparing either a yearly low dose CT scan or no screening. It is scheduled to enroll 4000 smokers and former smokers, and the study is scheduled to last 5 years, i.e. an initial (prevalence) screening is followed by 4 annual (incidence)
Primary Objective:
To determine if a treatment algorithm using serial transvaginal ultrasound with a tumor morphology index can improve the positive predictive value (PPV) of ovarian cancer screening compared to a historical control from 15% to 25%.
Secondary Objective To measure the compliance for
Axillary node extension is one of the major prognostic factors in breast cancer. Axillary dissection of Berg level I and II nodes is the validated method to obtain information on lymph node invasion, but it is associated with important morbidity.
Sentinel lymph node assessment (SLN) was developed to
Identification of Sentinel node:
- Arm 1 (Tc+blue dye): Identification of SLN using the standard technique of sub-areolar injection of technetium-99m (Tc-99m) and vital blue dye before surgery.
- Arm 2 (Tc+SPIO): Identification of SLN using standard isotope technique of sub-areolar injection of
