2. 1. Improved needle design to reduce the risk of infection in transrectal prostate biopsies

   Author : Andreas Forsvall; Translationell Sepsisforskning; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sepsis; biopsy; prostate cancer; infection; Forsvall needle; Needle biopsy; tru-cut biopsy needle; health economics; sepsis; Biopsy needle; Forsvall needle; tru-cut biopsy needle; infection; health economics; Prostate Cancer; complication; Needle : adverse effects; Needle biopsy; Needle;

   Abstract : This thesis addresses infections in prostate biopsy – a global problem. Over 3 million prostate biopsies are performed annually and 3% of men suffer a severe infection. The risk of infection is increasing in parallel with rising antibiotic resistance. READ MORE

4. 2. Heterogeneity and biopsy strategies in prostate cancer

   Author : Lars Egevad; Uppsala universitet; []
   Keywords : 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;

   Abstract : 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.

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

   Author : Shahin Abdsaleh; PG Lindgren; Per Skaane; Uppsala universitet; []
   Keywords : 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;

   Abstract : 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.

6. 4. Sentinel Node Biopsy in Breast Cancer : Clinical and Immunological Aspects

   Author : Jana de Boniface; Leif Bergkvist; Annika Håkansson; Omgo Nieweg; Uppsala universitet; []
   Keywords : Surgery; breast cancer; tumour immunology; sentinel node biopsy; CD3-zeta; CD28; Kirurgi;

   Abstract : The most important prognostic factor in breast cancer is the axillary lymph node status. The sentinel node biopsy (SNB) is reported to stage the axilla with an accuracy > 95 % in early breast cancer. Tumour-related perturbation of T-cell function has been observed in patients with malignancies, including breast cancer. READ MORE

7. 5. Sentinel Node Biopsy for Breast Cancer : Aspects and evolution

   Author : Andreas Karakatsanis; Fredrik Wärnberg; Peter Stålberg; Helena Olofsson; Lisa Rydén; Uppsala universitet; []
   Keywords : Breast Cancer; Sentinel Node Biopsy; Superparamagnetic Iron Oxide;

   Abstract : Sentinel Node Biopsy (SNB) in clinical practice was pivotal to the shaping of modern diagnosis, staging and treatment of patients with breast cancer. The use of radioisotope (RI) and blue dye (BD) has led to high detection rates with low false negatives, but delivery-of-care limitations connected to these tracers as well as the need for methods addressing new clinical conundrums delineates the urge for new tracers with comparable performance, easier logistics and, ideally expanded implementations.
