2. Optimizing prostate biopsy strategies for the diagnosis of prostate cancer.
Match Strength: 5.988

The importance of prostate biopsy in urologic practice has been magnified by the routine use of serum prostate-specific antigen in prostate cancer screening. Given the potential impact of the procedure on both patient care and health care costs, an optimal strategy for accurate and judicious detection of early prostate cancer is imperative. Maintaining maximal sensitivity and negative predictive value are equally important to the patient. In this article, we review recent modifications in prostate biopsy indications and techniques that may allow for a systematic biopsy approach to the patient ... Read More »

3. A case of needle tract implantation of hepatocellular carcinoma after percutaneous biopsy with an 18G Tru-cut needle.
Match Strength: 5.873

Needle tract implantation of hepatocellular carcinoma (HCC) is a rare complication of percutaneous biopsy, and it is largely associated with end-cutting needles or aspiration biopsy. The CT findings that have been reported include oval or round soft tissue nodules with persistent contrast enhancement along the needle tract, mostly in the subcutaneous tissue or the intercostal muscle layers. In this report, we describe a case of needle tract implantation of HCC after US-guided percutaneous biopsy with an 18G tru-cut needle ... Read More »

METHODS: We retrospectively reviewed the medical records of patients who underwent sonographically guided biopsy of soft tissue masses at our institution during a 50-month period. Core biopsy histopathologic results were compared with surgical or clinical follow-up. RESULTS: One hundred eighty-three patients, 76 male and 107 female, with a mean age of 48.5 years were included in the study.

6. African-American race is a predictor of prostate cancer detection: incorporation into a pre-biopsy nomogram.
Match Strength: 5.331

OBJECTIVES: To construct a pre-biopsy predictive model incorporating several clinical variables, including African-American (AA) or Caucasian race, to predict the risk of prostate cancer detection on prostate biopsy, as traditionally AA men have had a higher incidence of prostate cancer than Caucasian men, but previous predictive tools for prostate cancer have not incorporated the effect of race. PATIENTS AND METHODS: We evaluated 9473 patients undergoing initial prostate biopsy at three equal-access healthcare institutes from 1993 to 2003. At each biopsy session, patient age, race, serum ... Read More »

7. Lymphatic mapping and sentinel node analysis: current concepts and applications.
Match Strength: 5.127

Since the introduction of sentinel node biopsy in 1990 as a minimally invasive surgical technique for the diagnosis of melanoma lymphatic metastases, the number of applications has expanded. We review applications and the current status of sentinel node biopsy in melanoma, breast, colon, gastric, esophageal, head and neck, thyroid, and lung cancer. Variations on techniques specific to each organ are explained, and the current role of sentinel node biopsy in diagnosis and treatment is discussed. Publication Types: ... Read More »

8. Duration of pneumothorax as a complication of CT-guided lung biopsy.
Match Strength: 4.884

The purpose of this study was to determine management guidelines for biopsy-induced pneumothorax with the assistance of manual aspiration, mainly based on the duration of complicated pneumothorax. Data from 388 consecutive percutaneous needle lung biopsies were examined. Patients with pneumothorax on postbiopsy chest CT images underwent percutaneous manual aspiration with an 18-G i.v. catheter. Frequency and management of biopsy-induced pneumothorax and period to its disappearance were reviewed. Postbiopsy pneumothorax occurred in 133 of 388 (34.3%) procedures. Manual aspiration in 72 of these ... Read More »

9. CT-guided transthoracic needle biopsy using a puncture site-down positioning technique.
Match Strength: 4.656

OBJECTIVE: We have developed a new CT-guided technique using puncture site-down positioning during the biopsy. The goal of our study was to determine the efficacy and safety of this technique for biopsy of lung lesions compared with the standard technique. MATERIALS AND METHODS: Medical records of 236 patients who underwent CT-guided transthoracic needle biopsy were retrospectively evaluated. This study included 89 cases that were biopsied using the standard technique (group A) and 147 cases that were biopsied using the puncture site-down positioning technique (group B).

19. Prostate cancer: risk assessment and diagnostic approaches.
Match Strength: 3.815

The successful treatment of prostate cancer relies on detection of the disease at its earliest stages. Although prostate-specific antigen (PSA)-based screening has been a significant advance in the early diagnosis of prostate cancer, identifying specific genetic alterations in a given family or patient will allow more appropriate screening for early disease. Mapping and identification of specific prostate cancer susceptibility genes is slowly becoming a reality. Other prostate cancer risks include a family history, race, and possibly serum markers such as insulin-like growth factor-I (IGF-I). ... Read More »
