1. 1. Core Biopsy of Breast and Axillary Lesions : Technical and Clinical Aspects

   Författare :Shahin Abdsaleh; PG Lindgren; Per Skaane; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; Automatic core needle biopsy; Semiautomatic core needle biopsy; Surgical specimen; Dynamic needle behavior; Hormone Receptors; Radiologisk forskning; Radiological research; Radiologisk forskning;

   Sammanfattning : The aims of this work were to image and analyze the needle behavior at automated core biopsy, to investigate the clinical utility of an alternative core biopsy technique using a semiautomated gun in breast and axillary lesions, and also to compare core biopsy with surgical specimens in malignant breast lesions regarding histologic features and hormone receptor expression.In two experimental studies, using butter and silicon phantoms, respectively, the needle pass was imaged and its dynamic behavior studied.

   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Prostate cancer; core biopsy; tumor. volume; computer simulation; DNAploidy; tumor heterogeneity; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

   Sammanfattning : For the diagnosis of prostate cancer, there is a need to develop biopsy strategies, that give representative information both for detection of cancer and for assessment of prognostic indicators.In 80 men, transrectal core biopsies from 10 standardized positions were taken before radical prostatectomy.

4. 3. Comparison of stereotactic fine needle aspiration biopsy and core needle biopsy in breast lesions

   Författare :Karin Leifland; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Purpose: The purpose of this study was to evaluate the diagnostic value of two biopsy methods by comparing stereotactic fine needle aspiration biopsy (S-FNAB) with stereotactic core needle biopsy (S-CNB). The biopsies were performed by the same radiologist, in the same breast lesion on the same occasion, in order to establish which method that best can be recommended in different kind of mammographically detected lesions.

5. 4. Desmoid tumors. New aspects on diagnostic procedures, treatment and outcome

   Författare :Mikael Dalén; Göteborgs universitet; []
   Nyckelord :desmoid; fibromatosis; surgery; radiotherapy; chemotherapy; statistics; imaging; studies; cytology; biopsy; pathology;

   Sammanfattning : Desmoid tumor (aggressive fibromatosis) is a rare, benign fibroblastic/myofibroblasticneoplasm that originates from musculoaponeurotic structures. It never metastasizes but locallygrows aggressively and infiltrates surrounding tissues. The treatment of choice has beensurgery. However, local recurrences are frequent. LÄS MER

7. 5. Minimally-invasive breast interventions : methods for high yield, low risk, precision biopsy and curative thermal ablation

   Författare :Kai-Uwe Schässburger; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Advances in medical imaging and the introduction of population-based screening programs have increased the detection rate and overall proportion of small breast tumors. In addition, progress in technology and medical science, in combination with efforts to minimize morbidity, have resulted in the emergence of minimally invasive image-guided interventional procedures for both diagnosis and treatment of breast cancer.
