Abstract
AIM To examine the association between recall, needle biopsy, and cancer detection rates to inform the setting of target ranges to optimise the benefit to harm ratio of breast screening programmes. MATERIALS AND METHODS Annual screening programme information from 2009/10 to 2015/16 for the 80 screening units of the English National Health Service Breast Screening Programme (totalling 11.3 million screening tests) was obtained from annual (KC62) returns. Linear regression models were used to examine the association between needle biopsy rates and recall rates and non-linear regression models to examine the association between cancer detection rates and needle biopsy rates. RESULTS The models show and quantify the diminishing returns for prevalent screens with increasing biopsy rates. A biopsy rate increase from 10 to 20 per 1,000 increases the cancer detection rate by 2.13 per 1,000 with four extra biopsies per extra cancer detected. Increasing the biopsy rate from 40 to 50 per 1,000, increases the cancer detection rate by only 0.25 per 1,000, with 40 extra biopsies per extra cancer detected. Although diminishing returns are also seen at incident screens, screening is generally more efficient. CONCLUSIONS Increasing needle biopsy rates leads to rapidly diminishing returns in cancer detection and a marked increase in non-malignant/benign needle biopsies. Much of the harms associated with screening in terms of false-positive recall rates and non-cancer biopsies occur at prevalent screens with much lower rates at incident screens. Needle biopsy rate targets should be considered together with recall rate targets to maximise benefit and minimise harm.

Abstract
BACKGROUND Intraductal carcinoma of the prostate (IDC-P) is a distinct histopathologic feature associated with high-grade, advanced prostate cancer. Although studies have shown that IDC-P is a predictor of progression following surgical or radiation treatment for prostate cancer, there are sparse data regarding IDC-P on diagnostic needle biopsy as a prognosticator of prostate cancer mortality. MATERIALS AND METHODS This was a population-based study of all prostate cancer patients diagnosed using needle biopsy and without evidence of systemic disease between 1991 and 1999 within a defined geographic region of Norway. Patients were identified by cross-referencing the Norwegian Cancer Registry. Of 318 eligible patients, 283 had biopsy specimens available for central pathology review. Clinical data were obtained from medical charts. We examined whether IDC-P on diagnostic needle biopsy was associated with adverse clinicopathological features and prostate cancer mortality. RESULTS Patients with IDC-P on diagnostic needle biopsy had a more advanced stage and a higher Gleason score compared to patients without IDC-P. IDC-P was also associated with an intensively reactive stroma. The 10-year prostate cancer-specific survival was 69% for patients with IDC-P on diagnostic needle biopsy and 89% for patients without IDC-P (Log rank P-value < 0.005). The presence of IDC-P on diagnostic needle biopsy remained an independent predictor of prostate cancer mortality after adjustments for clinical prognostic factors and treatment. After adjustment for the newly implemented Grade Group system of prostate cancer, IDC-P showed a strong tendency toward statistical significance. However, IDC-P did not remain a statistically significant predictor in the multivariable analysis. CONCLUSION IDC-P on diagnostic needle biopsy is an indicator of prostate cancer with a high risk of mortality. Accordingly, a diagnosis of IDC-P on needle biopsy should be reported and considered a feature of high-risk prostate cancer. Moreover, the association between IDC-P and reactive stroma provides evidence in support of the idea that stromal factors facilitate carcinoma invasion to the prostatic acini and ducts.

Abstract
BACKGROUND Prostate needle biopsy (PNB) is required for the diagnosis of prostate cancer (PCa), but little is known about the frequency and clinical implication of false-negative results. OBJECTIVE To investigate the incidence and clinical impact of minute PCa missed on routine haematoxylin and eosin (H&E) slides, but retrieved by α-methylacyl-CoA-racemase (AMACR) immunohistochemistry. METHODS AMACR immunohistochemistry was used to detect PCa missed on H&E slides in a series of consecutive 1,672 PNB including 1,003 patients without evidence of PCa, and 669 patients with PCa meeting pathological criteria for active surveillance (PCAS) under current clinical investigation, including Gleason score ≤7 (3 + 4), <33% of biopsies involved by cancer, <50% of any core involved by cancer. Using improved multicore (pre-) embedding techniques a single AMACR immunostain/patient was sufficient to detect missed lesions. RESULTS In patients without histological evidence of PCa, AMACR immunohistochemistry retrieved minute PCa in 33 of 1,003 patients (3.29%) and atypical small acinar proliferations (ASAP) in 17 of 1,003 patients (1.69%). Among 116 of 669 (17.34%) PCa patients meeting PCAS, detection of additional core(s) involved by cancer was found responsible for disease reclassification in 63 of 116 of patients (54.31%). Limitations include the single-institutional design of the study. CONCLUSIONS PCa missed on routine H&E histology was retrieved by AMACR in 8.91% of PNB, including 17.34% of PCa patients meeting PCAS. 54.31% of them have finally lost their eligibility for active surveillance after detecting additional cores involved by cancer. Underdiagnosis of limited adenocarcinoma on PNB is a matter of concern, but can be prevented by a single AMACR immunostain/patient if improved multicore (pre-) embedding techniques are used.

Abstract
BACKGROUND Fine needle aspiration (FNA) cytology is the method of choice to exclude malignancy in thyroid nodules. A major limitation of thyroid FNA is the relatively high rate (13-17%) of non-diagnostic samples. The aim of this study is to determine the diagnostic yield of a screw needle compared to the conventional FNA. METHODS We retrospectively analysed thyroid nodule cytology of all patients that underwent thyroid nodule fine needle or screw needle aspiration between July 2007 and July 2012 in a single academic medical centre. Cytology results were categorized according to the Bethesda classification system. RESULTS In total, 644 punctures of thyroid nodules from 459 patients were available for analysis. The screw needle was used 531 times, and the conventional fine needle 113 times. The percentage of non-diagnostic cytology was significantly lower in the screw needle samples than in the fine needle samples (3% vs 17%, P<0.001). CONCLUSION This study shows a significantly better diagnostic performance of the screw needle compared to the conventional fine needle in cytology of thyroid nodules.

Abstract
INTRODUCTION A palpable lesion in the breast is usually subjected to triple assessment (clinical examination [CE], imaging and core biopsy [CB] or fine needle aspiration [FNA]) to minimise the risk of missing breast cancer. However, breast cancer is rare in young women, and triple assessment (especially CB) is invasive and expensive. Our aim was to see whether CB/FNA could be avoided in young women with benign findings on CE and imaging. METHODS This study analysed data from a prospectively entered database on female patients aged under 25 years who attended a rapid diagnosis breast clinic over a 68-month period. RESULTS Among 10,301 patients seen, 955 females (9.3%) were aged <25 years. The most common presenting complaint was a lump, followed by pain and nipple discharge. CE was normal or revealed benign findings in all except 15 patients, in whom it was indeterminate. Ultrasonography was performed in 692 patients (72%) and was normal (n=289) or benign (n=382) in all except 21 patients, in whom it was indeterminate. In six patients, both were indeterminate. A total of 317 patients (35%) had triple assessment: FNA in 106, CB in 239 and both in 9 cases. No cancers were diagnosed. CONCLUSIONS It would appear safe to omit FNA/CB in patients aged under 25 years when clinical and ultrasonography findings are normal or benign. This approach would have avoided needle biopsies in all but 30 patients (3%) in the study.

Abstract
To evaluate the diagnostic accuracy of computed tomography (CT)-guided percutaneous lung biopsy for solitary pulmonary nodules. Three hundred and eleven patients (211 males and 100 females), with a mean age of 59.6 years (range, 19-87 years), who were diagnosed with solitary pulmonary nodules and underwent CT-guided percutaneous transthoracic needle biopsy between January 2008 and January 2014 were reviewed. All patients were confirmed by surgery or the clinical course. The overall diagnostic accuracy and incidence of complications were calculated, and the factors influencing these were statistically evaluated and compared. Specimens were successfully obtained from all 311 patients. A total of 217 and 94 cases were found to be malignant and benign lesions, respectively, by biopsy. Two hundred and twenty-five (72.3%) carcinomas, 78 (25.1%) benign lesions, and 8 (2.6%) inconclusive lesions were confirmed by surgery and the clinical course. The diagnostic accuracy, sensitivity, and specificity of CT-guided percutaneous transthoracic needle biopsy were 92.9%, 95.3%, and 95.7%, respectively. The incidences of pneumothorax and self-limiting bleeding were 17.7% and 11.6%, respectively. Taking account of all evidence, CT-guided percutaneous lung biopsy for solitary pulmonary nodules is an efficient, and safe diagnostic method associated with few complications.

Abstract
BACKGROUND Vacuum-assisted core-needle biopsy (VAB) is increasingly used to perform breast biopsies instead of automated-gun core-needle biopsy (CNB). The significance of discordance between radiologic and pathologic findings has not been well established in the era of VAB predominance. This retrospective study was conducted to determine the rate of malignancy after surgical excisional biopsy (EXB) of these lesions at our two institutions. MATERIALS AND METHODS We reviewed medical records from January 2008-June 2013 to identify female patients who underwent EXB for a Breast Imaging-Reporting and Data System (BI-RADS) 4 or 5 lesions found to be benign and discordant on CNB. Clinicopathologic data were gathered, and analysis was performed using descriptive statistics. RESULTS A total of 8081 core biopsies were performed in the study timeframe. Six of 81 (7.4%) patients who had an EXB for a benign discordant breast lesion were found to have malignant pathology (two invasive, four in situ). Four of 63 (6.3%) lesions originally biopsied by VAB were upgraded, compared with 2 of 17 (11.8%) originally biopsied by CNB. There were no statistically significant differences in the rates of upgrade to malignancy when data were stratified by BI-RADS score or method of biopsy. CONCLUSIONS The overall rate of malignancy after EXB of benign discordant lesions was 7.4%. Despite the widespread adoption of VAB, EXB is still warranted for clarification of discordant radiologic-pathologic findings.

Abstract
OBJECTIVE To determine the impact of repeating prostate biopsies on the risk of detecting clinically insignificant prostate cancer (PCa) in larger prostate glands. METHODS We performed a retrospective cohort study using patients enrolled in our institutional PCa registry from 1991 to 2008 to assess the association of prostate volume and clinically insignificant PCa in men undergoing multiple prostate biopsies. Patients were stratified by prostate volume into 2 cohorts (<50 cm(3) or ≥50 cm(3)). Additionally, patients were stratified by prostate biopsy on which PCa was identified (1 biopsy or ≥3 biopsies). RESULTS Within the subgroup of patients with prostate volume ≥50 cm(3) requiring ≥3 biopsies before cancer diagnosis, 72.6% (45/62) had pathologic Gleason scores ≤6 and 81.6% (49/60) had an estimated tumor volume of ≤10% at the time of radical prostatectomy. This was significantly different from patients with prostate volume <50 cm(3) diagnosed on their first biopsy, in which only 48.5% (656/1349) were found to have Gleason scores ≤6 and 54.2% (705/1300) had estimated tumor volume ≤10% (P <.01). There was no significant difference in the rate of Gleason score upgrading at time of prostatectomy between any of the subgroups. CONCLUSION PCas detected in men with prostatic enlargement requiring multiple biopsies are more likely to be low-grade, low-volume tumors at final pathology than men without prostate enlargement. Men with larger prostates who have already had prior negative biopsies should be counseled regarding the increased risk of detecting clinically insignificant PCa with additional biopsies.

Abstract
BACKGROUND Accurate needle placement is the first concern in percutaneous MRI-guided prostate interventions. In this phantom study, different sources contributing to the overall needle placement error of a MRI-guided robot for prostate biopsy have been identified, quantified and minimized to the possible extent. METHODS The overall needle placement error of the system was evaluated in a prostate phantom. This error was broken into two parts: the error associated with the robotic system (called 'before-insertion error') and the error associated with needle-tissue interaction (called 'due-to-insertion error'). Before-insertion error was measured directly in a soft phantom and different sources contributing into this part were identified and quantified. A calibration methodology was developed to minimize the 4-DOF manipulator's error. The due-to-insertion error was indirectly approximated by comparing the overall error and the before-insertion error. The effect of sterilization on the manipulator's accuracy and repeatability was also studied. RESULTS The average overall system error in the phantom study was 2.5 mm (STD = 1.1 mm). The average robotic system error in the Super Soft plastic phantom was 1.3 mm (STD = 0.7 mm). Assuming orthogonal error components, the needle-tissue interaction error was found to be approximately 2.13 mm, thus making a larger contribution to the overall error. The average susceptibility artifact shift was 0.2 mm. The manipulator's targeting accuracy was 0.71 mm (STD = 0.21 mm) after robot calibration. The robot's repeatability was 0.13 mm. Sterilization had no noticeable influence on the robot's accuracy and repeatability. CONCLUSIONS The experimental methodology presented in this paper may help researchers to identify, quantify and minimize different sources contributing into the overall needle placement error of an MRI-guided robotic system for prostate needle placement. In the robotic system analysed here, the overall error of the studied system remained within the acceptable range.

Abstract
OBJECTIVES Bedside sonography for diagnosis of pneumothorax has been well described in emergency and trauma medicine literature. Its role in detection of iatrogenic pneumothorax has not been well studied. We describe the performance of bedside sonography for detection of procedure-related pneumothorax and highlight some limitations. METHODS A total of 185 patients underwent thoracentesis (n = 60), transbronchial biopsy (n = 48), and computed tomography-guided needle lung biopsy (n = 77). Bedside preprocedure and postprocedure transthoracic sonography and postprocedure chest radiograph were performed in all patients. Patients in whom the pleural surface was not well imaged with sonography were said to have a limited examination. Chest radiography was the standard for diagnosing pneumothorax. RESULTS Chest radiography showed pneumothorax in 8 of 185 patients (4.0%). These patients had undergone computed tomography-guided needle lung biopsy (n = 7) and transbronchial needle lung biopsy (n = 1). Sonography showed pneumothorax in 7 of these patients. The sensitivity, specificity, and diagnostic accuracy were 88%, 97%, and 97%, respectively. Limited-quality sonographic examinations due to preexisting lung disease were seen in 43 of 185 patients. The positive and negative likelihood ratios for patients with adequate scans were 55 and 0.17, respectively. The likelihood ratio for patients with limited-quality scans was 1.08. CONCLUSIONS When a good-quality scan is achieved, bedside chest sonography is a valuable tool for evaluation of postprocedure pneumothorax. Patients with preexisting lung disease, in whom the quality of the sonographic examination is limited, should be studied with chest radiography.

Abstract
OBJECTIVES To establish the value of MRI in targeting re-biopsy for undiagnosed prostate cancer despite multiple negative biopsies and determine clinical relevance of detected tumors. MATERIALS AND METHODS Thirty-eight patients who underwent MRI after 2 or more negative biopsies due to continued clinical suspicion and later underwent TRUS-guided biopsy supplemented by biopsy of suspicious areas depicted by MRI were identified. Diagnostic performance of endorectal 3T MRI in diagnosing missed cancer foci was assessed using biopsy results as the standard of reference. Ratio of positive biopsies using systematic versus MRI-prompted approaches was compared. Gleason scores of detected cancers were used as surrogate for clinical relevance. RESULTS Thirty-four percent of patients who underwent MRI before re-biopsy had prostate cancer on subsequent biopsy. The positive biopsy yield with systematic sampling was 23% versus 92% with MRI-prompted biopsies(p<0.0001). Seventy-seven percent of tumors were detected exclusively in the MRI-prompted zones. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy of MRI to provide a positive biopsy were 92%, 60%, 55%, 94% and 71%, respectively. The anterior gland and apical regions contained most tumors; 75% of cancers detected by MRI-prompted biopsy had Gleason score≥7. CONCLUSIONS Clinically relevant tumors missed by multiple TRUS-guided biopsies can be detected by a MRI-prompted approach.

Abstract
BACKGROUND Current guidelines recommend minimally invasive breast biopsy (MIBB) as the gold standard for the diagnosis of breast lesions. The purpose of this study was to describe geographic patterns and time trends in the use of MIBB in Texas. METHODS We used 100% Texas Medicare claims data (2000-2008) to identify women older than 66 years of age who underwent breast biopsy. Biopsies were classified as open or MIBB. Time trends, racial/ethnic variation, and geographic variation in the use of biopsy techniques were examined. RESULTS A total of 87,165 breast biopsies were performed on 75,518 breast masses in 67,582 women; 65.8% of the initial biopsies were MIBB. Radiologists performed 70.3% and surgeons performed 26.2% of MIBB. Surgeons performed 94.2% of open biopsies. Hispanic women were less likely to undergo MIBB (55.9%) compared with white (66.6%) and black (68.9%) women (p < 0.0001). Women undergoing MIBB were also more likely to live in metropolitan areas and have higher income and educational levels (p < 0.0001). The rate of MIBB increased from 44.4% in 2001 to 79.1% in 2008 (p < 0.0001). There are clear geographic patterns in MIBB use, with highest use near major cities. Although rates are increasing overall, rates of improvement in the use of MIBB vary considerably across geographic regions and remain persistently low in more rural areas. CONCLUSIONS Despite an increase in the use of MIBB over time, MIBB use was consistently lower than recommended. We must identify specific barriers in rural areas to effectively change practice and achieve the statewide goal of 90% MIBB.

Abstract
The aim of this study was to evaluate the prognostic implications of the sonographic appearance of prostate cancers. All patients with biopsy-proven prostate cancer between January 2003 and July 2004 (and at least 5 years of follow-up) were selected retrospectively. After exclusions, 101 patients constituted our study population and were divided into isoechoic (or nonvisible) and hypoechoic (or visible) lesion. The clinical outcomes of these two groups were compared. The outcomes for the two groups were significantly different (p < 0.01). For nonvisible lesions, 37 of the 41 patients (90.2%) had no disease relapse and 2 (4.9%) had biochemical failure. For the visible lesions, 37 of the 60 (61.6%) patients were free of recurrence, 7 (11.7%) had systemic metastases and 10 (16.7%) died of complications related to prostate cancer. Our data show that patients with nonvisible prostate cancer had significantly better outcomes than patients with visible lesions during a five-year period of evaluation.

Abstract
BACKGROUND Little is known about trends in the utilization or complication rates of transbronchial lung biopsy, particularly in community hospitals. METHODS We used the Healthcare Cost and Utilization Project Florida State Inpatient and State Ambulatory Surgical Databases to assess trends in transbronchial lung biopsy utilization in adults from 2000 to 2009. We subsequently calculated population based estimates of complications associated with transbronchial lung biopsy (iatrogenic pneumothorax and procedure-related hemorrhage) and identified characteristics associated with complications. RESULTS From 2000 to 2009, the age-adjusted rate of transbronchial biopsies per 100,000 adults in Florida decreased by 25% from 74 to 55 (p < 0.0001), despite stability in the overall utilization of bronchoscopy. Analysis of 82,059 procedures revealed that complications associated with transbronchial biopsy were uncommon and stable over the study period, with 0.97% (95% CI 0.94-1.01%) of procedures complicated by pneumothorax, 0.55% (95% CI 0.52-0.58%) by pneumothorax requiring chest tube placement, and 0.58% (95% CI 0.55-0.61%) by procedure-related hemorrhage. Patients with COPD (OR 1.51, 95% CI 1.31-1.75) and women (OR 1.32, 95% CI 1.15-1.52) were at increased risk for pneumothorax, while renal failure (OR 2.85, 95% CI 2.10-3.87), cirrhosis (OR 2.31, 95% CI 1.18-4.52), older age (OR 1.17, 95% CI 1.09-1.25) and female sex (OR 1.40, 95% CI 1.17-1.68) were associated with higher risk of procedure-related hemorrhage. CONCLUSIONS Utilization of transbronchial lung biopsy is decreasing relative to the overall use of bronchoscopy. Nevertheless, it remains a safe procedure with low risk of complications.

Abstract
RATIONALE AND OBJECTIVES To evaluate outcome of magnetic resonance (MR)-detected biopsied breast lesions ≤5 mm by correlating imaging characteristics with pathology. METHODS AND MATERIALS Institutional review board-approved retrospective review of 565 lesions biopsied with MR guidance between March 2004 and February 2009 found 68 lesions ≤5 mm in 61 patients. Lesions evaluated were those prospectively recommended for biopsy based on clinical setting, suspicious lesion morphology, and kinetics. Two study radiologists, blinded to final pathology, reviewed MR exams recording patient age, exam indication (staging, surveillance, diagnostic, or follow-up), mass location, size, morphology, T2-weighted signal, and kinetics. Chart review provided final pathology. RESULTS Of 68 masses ≤5 mm, 14 (20.6%) were malignant. Of 32 <5 mm, 32 (28.1%) were malignant. Of 14 malignancies, 7 (50%) were in patients with recently diagnosed breast cancer, 6 in the same breast, of which 4 (66.7%) were in same quadrant. Higher likelihood of malignancy based on proximity to known cancer was statistically significant (P = .01). No significant difference in proportion of malignancies was found based on age, T2-weighted signal, morphology, or kinetics. CONCLUSION For MR-detected biopsied masses, the positive predictive value for malignancy of those ≤5 mm was 20.6%. The highest prevalence of cancers was in the same quadrant as a newly diagnosed breast cancer. The decision to biopsy small masses should be based on carefully assessed MR features, and in the context of exam indication, not solely on size.

Abstract
OBJECTIVES To retrospectively compare the accuracy of fine-needle aspiration (FNA) and core-needle biopsy (CNB) for the diagnosis of thyroid malignancy METHODS We evaluated the results of FNA and CNB in 555 consecutive thyroid nodules with final diagnoses (malignancy 318, benign 237). All patients underwent FNA and CNB simultaneously for each nodule. We assessed the sensitivity, specificity and accuracy of FNA, CNB and FNA/CNB for the diagnosis of thyroid malignancy. RESULTS The sensitivity of FNA, CNB and FNA/CNB for thyroid malignancy was 68.6%, 86.8% and 90.6%, specificity 100%, 99.2% and 99.2%, and accuracy 82.0%, 92.1% and 94.2%, respectively. The sensitivity and accuracy of CNB or FNA/CNB for thyroid malignancy were significantly higher than those of FNA (P < 0.001). Compared with CNB alone, FNA/CNB was more accurate for thyroid malignancy only in small nodules less than 1 cm (P < 0.001). CONCLUSIONS Our clinical cohort data demonstrated that CNB was more accurate for the diagnosis of thyroid malignancy than FNA, and FNA/CNB was more accurate than CNB alone in small thyroid nodules. CNB will play a complementary role in optimal surgical decision-making and the management of thyroid nodules. KEY POINTS • CNB was more accurate for the diagnosis of malignancy than FNA. • Combined FNA/CNB was more accurate than CNB alone in small thyroid nodules. • CNB should play at least a complementary role in managing thyroid nodules.

Abstract
OBJECTIVES To evaluate whether magnetic resonance (MR) imaging features can predict the presence of occult invasion in cases of biopsy-proven pure ductal carcinoma in situ (DCIS). METHODS We retrospectively reviewed 92 biopsy-proven pure DCIS in 92 women who underwent MR imaging. The following MR imaging findings were compared between confirmed DCIS and invasive breast cancer (IBC): lesion size, type, morphological and kinetic assessments by ACR BI-RADS MRI, and findings of fat-suppressed T2-weighted (FS-T2W) imaging. RESULTS Sixty-eight of 92 (74%) were non-mass-like enhancements (NMLE) and 24 were mass lesions on MR imaging. Twenty-one of 68 (31%) NMLE and 13 of 24 (54%) mass lesions were confirmed as IBC. In NMLE lesions, large lesions (P = 0.007) and higher signal intensities (SI) on FS-T2W images (P = 0.032) were significantly associated with IBC. Lesion size remained a significant independent predictor of invasion in multivariate analysis (P = 0.032), and combined with FS-T2W SIs showed slightly higher observer performances (area under the curve, AUC, 0.71) than lesion size alone (AUC 0.68). There were no useful findings that enabled the differentiation of mass-type lesions. CONCLUSIONS Breast MR imaging is potentially useful to predict the presence of occult invasion in biopsy-proven DCIS with NMLE. KEY POINTS MR mammography permits more precise lesion assessment including ductal carcinoma in situ A correct diagnosis of occult invasion before treatment is important for clinicians This study showed the potential of MR mammography to diagnose occult invasion Treatment and/or aggressive biopsy can be given with greater confidence MR mammography can lead to more appropriate management of patients.

Abstract
Active surveillance is a solution to the widely acknowledged problem of overdiagnosis and overtreatment of clinically insignificant disease which accompanies early detection of prostate cancer using PSA and biopsy. It is an approach to the management of favorable risk prostate cancer which uses the opportunity provided by the long natural history of the disease to incorporate a period of initial observation into patient management. In this review article, the rationale, criteria for patient selection, method of follow up, trigger for intervention, and results of active surveillance are reviewed.

Abstract
OBJECTIVES To compare methodology and recommendations for the diagnosis of prostate cancer between the different clinical Guidelines currently existent. METHODS We searched for clinical practice Guidelines published in the period 2007-2009 in the web pages of the urological scientific associations, National Guideline clearinghouse, CMA infobase, and Trip database, as well as Pub Med. We found 4 clinical practice guidelines matching the search criteria. RESULTS All guidelines have been developed by a multidisciplinary team, performing a previous systematic review. All of them except the AUA translate the scientific evidence in recommendations, although each of them uses a different classification. Only one of them has been evaluated using the AGREE method. There are differences in the recommendation and use of diagnostic tests (PSA, digital rectal examination and prostatic biopsy) due to the fact that as a general rule they are based on low level scientific evidence. CONCLUSIONS Recommendations for the diagnosis of prostate cancer in all clinical practice guidelines are based on low levels of evidence, except in the use of antibiotic prophylaxis and anesthesia to perform a biopsy.

Abstract
With the pendulum swinging in low risk prostate cancer (PCa) to ideas of overtreatment and overdiagnosis more urologists are looking at Active Surveillance (AS) as a valid option for their low risk PCa patients. AS will undoubtedly hold a place as a management option in men with low risk PCa, however, it is critical to understand its limitations in its current form as highlighted in this article. We conducted a review of multiple computerized databases (Ovid, Medline, Pubmed, CINAHL, Cohrane Library database) with the keywords active surveillance, prostate neoplasm, and low risk PCa. Manual searches were also carried out. Assumptions of AS are discussed and their implications on selecting the appropriate AS candidate. As with any active treatment option offered to patients with PCa, those who are offered AS must be appropriately selected and counseled as to its risks and benefits.

Abstract
PURPOSE The aim of this study was to compare three devices in percutaneous excisional biopsy of clinically benign breast lesions in terms of complete excision rate, duration of procedure and complications. MATERIALS AND METHODS In a retrospective study from March 2005 to May 2009, 983 lesions underwent ultrasound-guided excisional biopsy with three vacuum-assisted systems, respectively. The lesions were category 3 lesions as determined by ultrasound imaging according to Breast Imaging Reporting and Data System (BI-RADS) (n=951) or had been confirmed as benign by a previous core needle biopsy (n=32). The completely excision rate, duration of procedure and complications (hematoma, pain and ecchymosis) were recorded. RESULTS 99.7% (980/983) lesions were demonstrated to be benign by pathology after percutaneous excisional biopsy. The overall complete excision rate was 94.8% (932/983). In lesions whose largest diameter equal to or larger than 1.5cm, the complete excision rates of EnCor(®) group (97.8%, 348/356) and Mammotome(®) group (97.2%, 139/143) were significantly higher than that of Vacora(®) group (91.9%, 445/484) (P<0.05). The EnCor(®) group (6.6±6.5min) had a significant less duration than Mammotome(®) (10.6±9.3min) and Vacora(®) group (25.6±23.3min) (P<0.05). Hematoma occurred more in EnCor(®) group and Mammotome(®) group than in Vacora(®) group (P<0.05). CONCLUSIONS All these three vacuum-assisted systems are highly successful for excisional biopsy of benign breast lesions.

Abstract
OBJECTIVE To analyze the acceptance rate and durability of surveillance among contemporary men with low-risk prostate cancer managed at a large, US academic institution. METHODS Patients with low-risk parameters on initial and repeat biopsy were offered surveillance regardless of age. Regular clinical evaluation and repeat prostate biopsy were recommended every 1-2 years, and intervention was recommended based on adverse clinical and pathologic parameters on follow-up. Acceptance rate of active surveillance, freedom from intervention, and freedom from recommended intervention were measured. RESULTS AND LIMITATIONS Of 202 low-risk patients, 86 (43%) chose immediate treatment and 116 (57%) underwent repeat biopsy for consideration of surveillance. Intervention was recommended after initial repeat biopsy in 27 (23%) men because of higher-risk features, leaving a total of 89 men on surveillance. Over a median follow-up of 33 months, 16 men were ultimately treated and 8 were recommended to undergo treatment because of adverse clinical features on subsequent evaluations. Of the men on surveillance, the 3-year freedom from intervention and freedom from recommended intervention was 87% (95% CI, 78-93) and 93% (95% CI, 85-97), respectively. CONCLUSIONS Acceptance of surveillance (57%) in low-risk patients in this series is substantially higher than previous reports, and approximately one-third of these patients are ultimately managed by surveillance using stringent criteria. The risk of reclassification to a more aggressive cancer over short-term follow-up in appropriately selected patients is low.

Abstract
PURPOSE The purpose of this retrospective study was to calculate the positive predictive value (PPV) of sonographic Breast Imaging Reporting and Data System (BI-RADS) categories 3, 4, and 5 in different age groups to investigate whether age influences the PPV of the BI-RADS category in breast ultrasound. MATERIALS AND METHODS From our sonography-guided core biopsy database of breasts between 2006 and 2008, we identified 2817 BI-RADS category 3, 4, and 5 lesions with known pathological diagnosis in 2587 women, all of whom underwent the earlier breast assessment via ultrasound with a sonographic BI-RADS lexicon and later sonography-guided core biopsy. All lesions were classified into three age groups (< 45, 45 - 59, and > 59 years). The age-related PPVs of each BI-RADS category among three age groups were calculated on the basis of pathological diagnoses and were compared using a χ(2)-test. RESULTS The overall PPV of each BI-RADS category was 2.2 % in category 3, 6.5 % in category 4a, 35.2 % in category 4b, 79.6 % in category 4c, and 99.6 % in category 5. The age-related PPVs of category 3 varied significantly among the three age groups (0.9 % versus 3.9 % versus 2.0 % p = 0.048), and notably, the age-related PPV in group 2 was higher than the others. Additionally, there was a significant positive association between the age-related PPVs and increasing age in categories 4a and 4b (4a, p < 0.0001 and 4b, p = 0.0139), but not in categories 4c and 5 (4c, p = 0.1853 and 5, p = 0.2871). CONCLUSION The incidence of female breast cancer differs not only in different sonographic BI-RADS categories, but also in different age groups. Therefore, more attention should be paid to the special age group that we found for sonographic BI-RADS categories 3, 4a, and 4b.

The pathological diagnosis was verified on clinical outcome in 129 cases (40 surgical resection, 53 thermal ablation, two medical treatment and 34 watchful waiting). Twenty-six patients underwent fine-needle aspiration biopsy (FNAB), 45 core-needle biopsy (CB) and 58 FNAB + CB. After review by two expert pathologists, cumulative accuracy of all FNAB (84) and all CB (103) was calculated. The rate of complications and mass management other than surgery was estimated. RESULTS The final diagnosis was malignancy in 97 cases (benign mass in 32). FNAB correctly diagnosed 64/84 masses (76.2%), CB 96/103 (93.2%). Of 58 masses submitted for both FNAB and CB, CB provided a 22.5% accuracy improvement. Major and minor complications occurred in 0% and 5.3%. Renal biopsy altered clinical management in 89/129 cases (68.9%), in terms of choosing therapeutic options other than surgery. CONCLUSION CB is more accurate than FNAB and should be preferred in renal mass biopsy. FNAB may precede CB when an expert pathologist can immediately evaluate the samples. Renal biopsy influences renal mass management.

Abstract
OBJECTIVE We evaluated radiation doses, complication rates, and diagnostic accuracy for CT-guided percutaneous needle aspiration biopsy (NAB) procedures of pulmonary lesions performed with or without fluoroscopic guidance. METHODS A total of 142 patients were prospectively enrolled to receive CT-guided NAB with (Group I, n = 72) or without (Group II, n = 70) fluoroscopic guidance. Outcome measurements were patient and doctor radiation dose, and complication rate. Sensitivity, specificity and accuracy were calculated based on 123 NAB results. RESULTS The mean estimated effective patient radiation dose was 6.53 mSv in Group I and 2.72 mSv in Group II (p < 0.001). The mean estimated effective doctor dose was 0.054 mSv in Group I and 0.029 mSv in Group II (p < 0.001). The complication rate was significantly different between the two groups (13.4% versus 31.4%, p = 0.012). Sensitivity, specificity and accuracy for diagnosing pulmonary lesions were 97.8%, 100% and 98.4% in group I and 95.3%, 100% and 89.5% in group II (p > 0.05). CONCLUSIONS CT fluoroscopy-guided NAB of pulmonary lesions provides high diagnostic accuracy and can be performed with significantly fewer complications. However, radiation exposure to both patient and doctor were significantly higher than conventional CT-guided NAB.

Abstract
OBJECTIVES To evaluate PCa incidence in patients with one or more negative extended prostate biopsy who underwent repeat biopsy or TURP. MATERIAL AND METHODS From June 2003 to February 2008, 308 patients were submitted to repeat prostate biopsy (median 20.5 cores) and 120 patients underwent TURP after one or more 12 cores prostate biopsy. Indications for biopsy were: abnormal DRE; PSA > 10 ng/mL; PSA included between 4.1-10 or 2.6-4 ng/mL with free/total PSA < or = 25% and < or = 20%, respectively 262 and 46 underwent a second and a third biopsy: 218 because for high levels of PSA, 40 and 50 patients for a previous diagnosis of HGPIN and ASAP, 28 had an abnormal DRE. PSA in patients who underwent TURP was 11.6 ng/mL (median); in all cases DRE was negative and only 76 patients referred LUTS. RESULTS PCa incidence at repeat biopsy was 16.9%; 96.2% of cancers were diagnosed at a second biopsy and 3.8% at a third one. PCa incidence was higher in patients with previous ASAP (43.4% and 50%) vs patients with HGPIN (25% and 0%) or benign pathology (11.9% and 0%). PCa was diagnosed in 11.1% and 19% of patients who underwent TURP previously submitted to a first and a second biopsy, respectively. CONCLUSIONS In case of persistent suspicion of PCa after a repeated negative saturation biopsy, TURP should be proposed as part of the diagnostic procedure aside from LUTS, especially in patients with a life expectancy greater than 10 years.

Abstract
BACKGROUND Needle biopsy of the prostate is a common outpatient procedure. In March 2009, the European Association of Urology (EAU) published an updated, evidence-based "Guidelines on Prostate Cancer," including recommendations for this procedure. OBJECTIVE To survey onco-urology specialists attending the 6th European Section of Oncological Urology (ESOU) meeting in Istanbul, Turkey in January 2009, to assess their biopsy practices and compare them with March 2009 EAU guidelines. DESIGN, SETTING AND PARTICIPANTS The authors designed a questionnaire and distributed it to 606 conference delegates. It was completed by 298 delegates, of whom 156 were experienced onco-urological specialists. MEASUREMENTS The survey results from the 156 experienced onco-urologist specialists were analyzed. RESULTS AND LIMITATIONS Most (59%) of the 156 respondents worked in large (> 20 bed) units, and 76% said urologists always performed the biopsies. Transrectal ultrasound (TRUS)-guided biopsy was the preferred procedure for 78% of respondents. Prostate-specific antigen (PSA) cut-off points of 4 ng/mL, 3.5 ng/mL, 3 ng/mL, and 2.5 ng/ml were used by 42%, 18%, 23%, and 8% of respondents, respectively, to determine whether a biopsy was indicated. A total of 95% of respondents gave patients prophylactic antibiotics. Another of 15% and 17% of respondents did not advise patients to stop taking warfarin or clopidogrel, respectively. A total of 23% of respondents did not give patients pre-procedure anesthesia, while others gave patients periprostatic lidocaine (31% of respondents), topical lidocaine jelly (35%), or general or spinal anesthesia (5.7%). High grade prostatic intraepithelial neoplasia (HGPIN) was considered by 71% of respondents as being a pre-malignant condition requiring a repeat biopsy. If atypical small acinar proliferation (ASAP) was reported, 62% of respondents recommended a repeat biopsy. Magnetic resonance imaging (MRI) was used to help diagnose cancer (53% of respondents), help stage cancer (83%), or help diagnose cancer recurrence (62%). Study limitations include possible difficulties with the English questionnaire. CONCLUSIONS Many surveyed specialists were not performing prostate biopsies according to March 2009 evidence-based EAU practice guidelines, which could have adverse consequences for patients.

Abstract
BACKGROUND CT-guided biopsy is a minimally invasive diagnostic method of evaluating musculoskeletal lesions. Other options include incisional and excisional biopsy with the possibility of intraoperative frozen section. The clinician's decision to order a CT-guided biopsy requires an understanding of the likelihood that this biopsy will affect treatment This requires an understanding of both diagnostic yield and accuracy. Furthermore, the clinical utility of a biopsy is affected by factors other than the yield and accuracy as the clinical setting may render a technically diagnostic biopsy unhelpful. METHODS A retrospective review of the electronic record at an orthopedic oncology referral center identified all patients who had undergone CT-guided percutaneous needle biopsy of musculoskeletal lesions after being evaluated by an orthopedic oncologist in clinic over a period of 5 years. 53 CT-guided biopsies of bone lesions and 16 CT-guided biopsies of soft tissue lesions were identified. The diagnostic yield (rate of obtaining tissue from which the pathologist could report a diagnosis) and clinical utility (rate at which biopsy results guided treatment decisions) were calculated and statistically compared. RESULTS The overall diagnostic yield of CT-guided bone biopsies was 94% (50 of 53 biopsies) and the clinical utility was 70% (37 of 53 biopsies). In the first 2 years of the study the diagnostic yield was 95% (21 of 22 biopsies) and the clinical utility was 86% (19 of 22 biopsies). In the remaining 3 years the diagnostic yield was 91% (28 of 31 biopsies) and the clinical utility was 58% (18 of 31 biopsies). This decrease in clinical utility over time was statistically significant (p = 0.01). Suspicion of metastasis resulted in a diagnostic yield of 100% (11/11) and a clinical utility of 91% (10/11). Suspicion of primary tumor resulted in a diagnostic yield and clinical utility of 93% (39/42) and 67% (28/42), respectively. This difference in clinical utility was statistically significant (p = 0.02). The diagnostic yield of CT-guided soft tissue biopsies was 75% (12 of 16 biopsies) and the clinical utility was 69% (11 of 16 biopsies). The diagnostic yield was significantly lower for soft tissue biopsy than bone biopsy (p = 0.01). There was no relationship between the rate of diagnostic biopsies and the evaluating pathologist or the location of the lesion within the body. CONCLUSIONS CT-guided biopsy is useful in the diagnosis of musculoskeletal lesions, however, its clinical utility is substantially lower than its diagnostic accuracy and yield due to a significant rate of diagnostic biopsies that fail to guide treatment, particularly when a primary lesion is suspected. The disparity in clinical utility based on preoperative suspicion of metastasis was even greater in our study than previously shown. CT-guided percutaneous needle biopsy is much more likely to guide treatment in the setting of suspected bone metastasis as opposed to biopsies of suspected primary bone lesions and soft tissue lesions.

Abstract
PURPOSE We determined whether serial prostate needle biopsies predispose men to erectile dysfunction and/or lower urinary tract symptoms over time. MATERIALS AND METHODS Men with prostate cancer on an active surveillance protocol were administered the 5-item Sexual Health Inventory for Men and International Prostate Symptom Score questionnaires on protocol entry, and at a cross-sectional point in 2008. All men had at least 1, 10 to 12-core prostate biopsy at protocol entry and yearly surveillance biopsies thereafter were recommended. RESULTS Of 333 men 231 returned the followup questionnaires. Correlations were found between biopsy number and erectile dysfunction, with increasing biopsy number associated with a decrease in Sexual Health Inventory for Men score (p = 0.04) and a history of 3 or more biopsies associated with a greater decrease in Sexual Health Inventory for Men score than after 2 or fewer biopsies (p = 0.02). Multivariable analysis for biopsy number, age, prostate volume and prostate specific antigen showed that only biopsy number was associated with decreasing Sexual Health Inventory for Men score (p = 0.02). When men were stratified by baseline Sexual Health Inventory for Men, those without preexisting erectile dysfunction (Sexual Health Inventory for Men score 22 to 25) trended toward steeper decreases in Sexual Health Inventory for Men score after 3 or more biopsies (p = 0.06) than did men with baseline mild to moderate erectile dysfunction (Sexual Health Inventory for Men score 8 to 21). No correlation was found between biopsy number and International Prostate Symptom Score. CONCLUSIONS Serial prostate biopsies appear to have an adverse effect on erectile function in men with prostate cancer on active surveillance but do not affect lower urinary tract symptoms.

Abstract
PURPOSE To determine the frequency with which stereotactic 11-g vacuum-assisted breast biopsy (11-g SVAB) obviates an open surgical biopsy (OSB), to compare the costs of these two biopsy methods, and to estimate the potential cost savings attributable to 11-g SVAB in the diagnosis of suspicious breast lesions in patients in Austria. MATERIALS AND METHODS We retrospectively reviewed 318 consecutive breast lesions of BI-RADS categories IV and V (microcalcifications n=166; masses n=152) on which 11-g SVAB and OSB were performed. Cost savings were calculated using nationally allowed flat rates and patient charges. Costs were measured from a hospital and a socioeconomic perspective. Common clinical scenarios and sensitivity analyses assessed the extent of achievable cost savings. RESULTS 11-g SVAB obviated the need for an OSB in 93 (29%) of 318 women. Overall cost savings per 11-g SVAB over OSB were € 242 per case from a hospital perspective, and € 422 per case from a socioeconomic perspective. The use of 11-g SVAB decreased the cost of diagnosis by 7% from a hospital perspective, and by 10% from a socioeconomic perspective. CONCLUSION In Austria, annual national savings of over 5 million Euro could be realized with the use of 11-g SVAB for the diagnosis of suspicious breast lesions. Although savings per case are modest, the national health care system realizes significant cost reduction as women benefit from a faster and less invasive approach to diagnosis.

Abstract
AIM To determine the patient characteristics, referral patterns and delays in assessment and treatment of patients with primary lung cancer in South Auckland, New Zealand and compare with international standards. METHODS Retrospective review of the clinical records of 80 patients referred to a secondary care respiratory service and diagnosed with primary lung cancer in 2004. RESULTS Eighty-five percent of inpatient referrals and 48.5% of outpatient referrals were for advanced stage lung cancers. The median interval from receipt of outpatient referral to first chest physician assessment was 18 days, with median interval from the first chest physician assessment to bronchoscopy of 17 days and for staging CT chest of 16 days. For patients requiring a CT-guided percutaneous needle aspiration for diagnosis, there was a further median delay of 37 days after the initial CT scan. The median interval from the date of receipt of initial outpatient referral to diagnosis was 38 days, but for early stage lung cancers it was 54 days. The median interval to diagnosis for inpatient admissions was 6 days after the first respiratory assessment. CONCLUSION The intervals for initial assessment, diagnosis and treatment of lung cancer in South Auckland do not meet the recommendations of international guidelines, especially for early stage lung cancers. Organisational and resource changes are required at each point in the diagnostic and management pathway to reduce delays.

Abstract
OBJECTIVE To evaluate the role of transbronchial needle aspiration (TBNA) in the diagnosis of patients with enlarged mediastinal and/or hilar lymph node. METHODS Patients with mediastinal and/or hilar lymphoadenopathy proven by CT scan were eligible for TBNA as reported. All specimens were directly and instantly smeared for pathological examination. RESULTS From June 1 2004 to December 31 2007, 164 patients were examined: including 80 lung cancers, 69 lung benign diseases, 2 other malignancy tumor, and 13 without definite diagnosis. Total 260 lymph nodes were punctured. TBNA procedures were successfully carried out in 445/463 (96.1%). Sensitivity of TBNA was 82.5% (66/80) in patients who had been proven to suffer from bronchogenic carcinoma. There were 25 patients that diagnosis of lung cancer was pathologically determined by TBNA only. A total of 122 lymph nodes in the 80 lung cancer patients were aspirated by TBNA with a positive rate of 65.6% (80/122). Severe complications were rare except small amount of bleeding at the TBNA site (100/164, 61.0%). From June 1 2006 to December 31 2007, lymph node tissues able to make histology diagnosis were yield in 73.5% (64/87) patients. Through histology pathology, the sensitivities of TBNA were 53.3% (8/15) for sarcoidosis and 78.6% (33/42) for lung cancer. CONCLUSION TBNA is quite safe and helpful in diagnosis and staging of bronchogenic carcinoma, and in diagnosis of benign lung diseases.

Abstract
BACKGROUND Preoperative diagnosis of breast cancer is a standard of care. We conducted a population-based study to determine the factors associated with the use of percutaneous needle biopsy to diagnose breast cancer in Ontario. METHODS We identified a total of 3644 women who underwent breast tissue sampling (percutaneous needle biopsy or surgical excision) that yielded a diagnosis of cancer between Apr. 1, 2002, and Dec. 31, 2002, and for whom we were able to obtain complete data. We performed univariate and multivariate analyses to examine the association between a number of variables and the use of percutaneous biopsy or surgery for diagnosis and the performance of biopsy with or without image guidance. The variables were age, local health integration network (LHIN), income quintile, urban or rural residence, access to a primary care provider, prior mammogram, prior regular screening mammography, screen-initiated biopsy, and surgeon and radiologist specialization in breast disease. RESULTS A total of 2374 women (65%) underwent percutaneous biopsy to diagnose breast cancer. The use of percutaneous biopsy varied from 22% to 81% among LHINs. On multivariate analysis, no patient variables were associated with the use of percutaneous biopsy for diagnosis. Only the LHIN and surgeon and radiologist specialization were predictive of whether a woman received a percutaneous biopsy. These 2 variables, along with income quintile and screen-initiated biopsy, were associated with the use of image-guided biopsy as the method of choice. CONCLUSION Geographic variation in the use of percutaneous biopsy, particularly image-guided biopsy, for the diagnosis of breast cancer exists across Ontario. The frequency of such biopsies may be a useful quality indicator. Strategies to improve uptake of organized evidence-based care may increase the use of percutaneous biopsy.

Abstract
CONTEXT Endoscopic ultrasound-guided trucut biopsy (EUS TCB) has a lower yield than fine needle aspiration (FNA) in pancreatic masses but the additional use of TCB to FNA may improve the diagnostic accuracy over FNA alone. OBJECTIVE To compare the yield of EUS FNA alone or combined with EUS TCB for diagnosis of pancreatic masses. DESIGN Single center retrospective case control study conducted at academic tertiary center. Study conducted between March 2004 and April 2007. PARTICIPANTS A total of 126 consecutive patients referred for EUS guided biopsy of pancreatic mass; three patients excluded from analysis, final cohort comprised 123 patients (108 malignant and 15 benign). EUS FNA was performed in 72 patients and EUS FNA+TCB was performed in 51 patients. MAIN OUTCOME MEASURES The diagnostic performance of EUS FNA versus EUS FNA+TCB was compared. RESULTS The sensitivity, specificity and frequency of cases correctly identified for malignancy of FNA alone were 87.1% (54/62), 100% (10/10) and 88.8% (64/72), while for the combination of FNA+TCB they were: 95.7% (44/46), 100% (5/5) and 96.0% (49/51), respectively (P=0.184, 1.000, and 0.193 FNA versus FNA+TCB). No major complication occurred in either group. CONCLUSION FNA+TCB can be safely performed in selected lesions but sensitivity is not statistically improved over FNA alone (95.7% versus 87.1%).

Abstract
OBJECTIVE To assess the diagnostic value of core needle biopsy (CNB) before neoadjuvant chemotherapy for breast cancer. METHODS One hundred and nineteen breast cancer cases underwent neoadjuvant chemotherapy in our hospital during the period from June, 2005 to January, 2007 were analyzed. CNB was carried out before starting chemotherapy. The hematoxylin and eosin-stained slides of CNB taken before and after neoadjuvant chemotherapy were reviewed independently by two pathologists, and the rate of consistency was verified. RESULTS Amongst the 119 cases studied, 110 cases were confirmed to be carcinoma, including 105 cases of invasive carcinoma and 5 cases of ductal carcinoma-in-situ. The rate of consistency was 97.22% (105/108). CONCLUSION CNB has important value in distinguishing benign from malignant lesions, as well as in confirming the diagnosis of invasive carcinoma before starting neoadjuvant chemotherapy.

Abstract
OBJECTIVE To investigate the feasibility of testing for prostate cancer and the prevalence and characteristics of the disease in unselected young men. DESIGN Prospective cohort nested within a randomised controlled trial, with two years of follow-up. SETTING Eight general practices in a UK city. PARTICIPANTS 1299 unselected men aged 45-49. INTERVENTION Prostate biopsies for participants with a prostate specific antigen level of 1.5 ng/ml or more and the possibility of randomisation to three treatments for those with localised prostate cancer. MAIN OUTCOME MEASURES Uptake of testing for prostate specific antigen; positive predictive value of prostate specific antigen; and prevalence of prostate cancer, TNM disease stage, and histological grade (Gleason score). RESULTS 442 of 1299 men agreed to be tested for prostate specific antigen (34%) and 54 (12%) had a raised level. The positive predictive value for prostate specific antigen was 21.3%. Ten cases of prostate cancer were detected (2.3%) with eight having at least two positive results in biopsy cores and three showing perineural invasion. One tumour was of high volume (cT2c), Gleason score 7, with a positive result on digital rectal examination; nine tumours were cT1c, Gleason score 6, and eight had a negative result on digital rectal examination. Five of the nine eligible participants (55%) agreed to be randomised. No biochemical disease progression in the form of a rising prostate specific antigen level occurred in two years of follow-up. CONCLUSIONS Men younger than 50 will accept testing for prostate cancer but at a much lower rate than older men. Using an age based threshold of 1.5 ng/ml, the prevalence of prostate cancer was similar to that in older men (3.0 ng/ml threshold) and some cancers of potential clinical significance were found. TRIAL REGISTRATION Current Controlled Trials ISRCTN20141297.

Abstract
BACKGROUND The Mammotome is a diagnostic tool used under stereotactic or with ultrasound guidance. A clear indication for Mammotome use under stereotactic guidance is when a non-palpable microcalcification is a target. However, the indications for the use of the Mammotome under ultrasound guidance vary among institutions, and it is difficult to find a place for the Mammotome among conventional biopsy techniques. The Mammotome biopsy has been available in our hospital since July 1999. We assessed the effectiveness and indications of ultrasound-guided Mammotome biopsy. METHODS We performed Mammotome biopsies in 433 cases requiring histological diagnosis from July 1999 to September 2006, using an 11-gauge articulated arm-type Mammotome under ultrasound guidance. There were 377 mass lesions including 83 non-palpable cases and 56 hypoechoic lesions. RESULTS The indications for Mammotome biopsy were 162 cases with inconsistent fine needle aspiration (FNA) and imaging findings, 114 cases indeterminate by FNA, 68 cases of an identified pathological type before neoadjuvant chemotherapy and confirmation of hormone receptor status, 36 inadequate cases by FNA, 20 cases of confirmation of fibroadenoma and other benign tumors, 8 removal cases of fibroadenoma, 8 microcalcification cases, and 17 others. The target lesion was obtained in 99.5% of the cases. CONCLUSIONS Ultrasound-guided Mammotome biopsy is an accurate and useful diagnostic method that enables sufficient amounts of tissue to be obtained with minimal invasion and few complications. The Mammotome is the first choice for obtaining a definitive pathological diagnosis in breast lesions.

Abstract
PURPOSE To determine the importance of increasing the number of biopsy cores to decrease the discrepancy of Gleason scores of needle biopsy and radical prostatectomy specimens. MATERIALS AND METHODS Between May 1998 and July 2005, 392 patients with clinically localized prostate cancer diagnosed by 18-gauge transrectal needle biopsy underwent radical prostatectomy. We categorized the cohort into 2 groups according to the number of the cores. Group 1 consisted of 206 patients diagnosed by extended biopsies (> or =10 cores, range 10-14, median 11). The remaining 186 patients who were diagnosed by sextant biopsies were categorized as being in group 2. Preoperative clinical variables, including patient age, digital rectal examination findings, serum prostate-specific antigen, and the number of cores positive for cancer the parameters, were assessed in both groups. The concordance of Gleason scores in both groups were analyzed by both individual Gleason scores and clinical subgroups of Gleason scores: 2-4 (well differentiated), 5-6 (moderately differentiated), 7 (intermediate), and 8-10 (poorly differentiated). RESULTS Needle biopsies revealed moderately differentiated tumors (Gleason 5-6) for the 2 groups (55.3% and 60.2%). Gleason scores of the needle biopsies were identical to that of the prostatectomy specimen in 116 (56.31%) and 76 cases (40.86%) for each group (kappa: 0.432 and 0.216 for each group, respectively). Gleason score of the needle biopsy differed by 1 grade in 56 (27.18%) and 84 cases (45.16%), and by > or =2 units in 34 (16.50%) and 26 cases (15.05%) for each group, respectively. Of the specimens, 34% were undergraded, and 10% were overgraded in group 1. These rates were 38% and 22% in group 2, respectively. A total of 70% in group 1 and 56% in group 2 remained in the same categorical group, 28% and 32% of the specimens were undergraded, and 4% and 12% were overgraded in groups 1 and 2, respectively. In group 1, the number of patients with Gleason scores of 2-4, 5-6, 7, and 8 were 9.7%, 55.3%, 21.4%, 13.6%, and 1.9%, 47.6%, 32%, 18.4%, graded by needle biopsies and radical prostatectomy specimens, respectively. However, in the sextant group, the change was the number of patients with Gleason scores of 2-4, 5-6, 7, and 8-10 was 5.4% 60.2%, 24.7%, and 9.7%, detected by needle biopsies, respectively. Radical prostatectomy specimens revealed the same Gleason categories in 4.3%, 41.9%, 38.7%, and 15.1%, respectively. There was no correlation between categorized prostate-specific antigen levels and concordance of the Gleason grade. Age and digital rectal examination results did not affect Gleason correlation. CONCLUSIONS We have shown that an extended biopsy scheme beyond its superior diagnostic capability also improves the concordance of Gleason scores of needle biopsies and radical prostatectomy specimens.

Abstract
OBJECTIVE To assess the effects on the performance characteristics, in a prostate-cancer detection programme using prostate-specific antigen (PSA) levels, of a lower PSA threshold and the incorporation of reflex (free or complexed PSA) tests. METHODS We reviewed publications and extracted data on PSA distributions and performance characteristics of the PSA test and isoform tests from population-based surveys. We estimated the rate of biopsy, cancers detected, and cancers missed that would result from lowering PSA thresholds and including reflex testing. RESULTS Lowering the PSA threshold for biopsy referral to 2 ng/mL would increase the number of referrals from 110 to 230 per 1000 men tested, with most of the extra biopsies being among men with no cancer, i.e. an increase from 74 to 172 per 1000 men tested. However, this increased testing would result in an increase in the cancer-detection rate from 3.6% to 5.8%. Including a reflex test for men with moderately elevated PSA levels has little effect on programme performance, with only a modest (10-15%) reduction in unnecessary biopsies and a small increase in the numbers of missed cancers. CONCLUSIONS Lowering PSA thresholds, with or without the concurrent introduction of reflex tests, would increase both the numbers of cancers detected and the number of patients referred for biopsy procedures, of which most would be unnecessary. As the extra cancers detected are likely to be clinically localized, and with no evidence that their treatment improves the outcome of the disease, such changes place a possibly unjustified additional burden on the healthcare provider.

Abstract
PURPOSE To investigate the number of cores required to diagnose breast cancer using ultrasound (US)-guided core needle biopsy. METHODS US-guided core biopsy of 150 masses was performed in 144 patients. For each mass, 6 cores were obtained and analyzed separately. The histopathologic diagnosis was classified as benign, malignant, or normal breast tissue. Each core was analyzed separately. For diagnostic purposes, the cases were grouped as follows: group G1 comprised the first core; group G2 comprised the first and second core; group G3 comprised the first 3 cores; up to group G6, which included all 6 cores. The results were also analyzed by tumor size (</=2 cm and >2 cm). RESULTS The sensitivity in the diagnosis of breast cancer was 90.1% in group G1 and 94.1% in the remaining groups (G2-G6). In tumors </=2 cm, the sensitivity was 88.4% for group G1 and 90.7% for the others, whereas for tumors >2 cm the sensitivity was 91.4% for group G1 and 96.6% when 2 or more cores were obtained. CONCLUSION It appears that 2 cores are sufficient to diagnose breast cancer in this study population assuming no technical error occurred in US guidance of the needle through the mass.

Abstract
OBJECTIVE This study investigates the changing indications, results, and practice patterns of brain biopsy in patients with acquired immunodeficiency syndrome (AIDS) as treatment evolved with the development of highly active antiretroviral therapy (HAART). METHODS We collected data on 246 patients with AIDS who were undergoing brain biopsy of intracranial lesions. Patients were managed in accordance with a uniform protocol. Patients were divided into two groups of those biopsied in the era before (1992-1996) or after (1997-2001) the use of HAART. RESULTS The introduction of HAART led to a steep decrease in the number of biopsies performed annually. The protocol functioned well. Diagnoses were obtained for 92.3% of patients. Lymphoma was the most frequent diagnosis (52.9% of patients), followed by progressive multifocal leukoencephalopathy (18.9% of patients) and toxoplasmosis (8.1% of patients). No patient who underwent lesion biopsy for reasons of negative toxoplasmosis titers or atypical radiology evaluation was diagnosed with toxoplasmosis. Nineteen patients who experienced failed toxoplasmosis treatment were diagnosed with toxoplasmosis. Toxoplasmosis titers had a high specificity and a negative predictive value. Patients with progressive multifocal leukoencephalopathy or nondiagnostic biopsies were more likely to have solitary lesions. The average Karnofsky performance score at the time of biopsy was 72.4, which is still within the range of independent functioning. Significant intracerebral hemorrhages were only observed in patients with lymphoma who also had low platelet counts. CONCLUSION Although the number of patients with AIDS who require brain biopsy has decreased, the procedure still has merits. The paradigm we developed was useful for selecting patients for early biopsy. Patients with AIDS who also have intracerebral lesions should have toxoplasmosis titers performed, and those whose titers are negative for toxoplasmosis should undergo early brain biopsy.

Abstract
Prostate cancer is the most common neoplasia of middle-aged men. Prostate specific antigen (PSA) is the first FDA-approved tumour marker for early detection of cancer and it is now in widespread clinical use. The discovery of different PSA molecular forms in serum (free PSA, PSA complexed with various protease inhibitors) in the early 1990s renewed clinical research to enhance the specificity of PSA. Also, the use of a homologous prostate-localised antigen, human glandular kallikrein 2 (KLK2) may further reduce the number of unnecessary prostate biopsies. More recently, promising data is emerging regarding molecular forms of free PSA (proPSA, BPSA, 'intact' PSA) and other members of the expanded human kallikrein family. These new findings may add substantial clinical information for early detection of prostate cancer.

Abstract
OBJECTIVE The procedure of prostate biopsy is often performed but has not been standardized. Therefore, a survey of all urologists in Switzerland was carried out to investigate indications, patient preparation and technique with regard to transrectal prostate biopsy. MATERIAL AND METHODS A questionnaire was mailed to all 178 urologists working in Switzerland, either as self-employed urologists (SEUs) or as employed urologists at a hospital (EUHs), i.e. a teaching centre. RESULTS The questionnaire was returned by 133 urologists (75%). Eighty-seven of the respondents (65%) are SEUs and 46 (35%) work as EUHs. If digital rectal examination (DRE) raises suspicion of cancer, 129 urologists perform a biopsy. A serum prostate-specific antigen (PSA) level of 4 ng/ml is used as a cut-off value by 84% of respondents (SEUs 83%, EUHs 87%). A fluoroquinolone antibiotic is prescribed by 126 of the respondents. Fifty-nine percent of respondents (SEUs 52%, EUHs 72%) are offering periprostatic injection of a local anaesthetic drug. At the initial biopsy, 24% of respondents (SEUs 30%, EUHs 13%) obtain six cores, 45% (SEUs 37%, EUHs 61%) 8-10 and 17% (SEUs 18%, EUHs 15%) > or =12. The subsequent procedure performed after two negative biopsy sessions varies considerably. CONCLUSIONS This survey provides an insight into the practice pattern of urologists in Switzerland concerning prostate biopsy. For almost all urologists, a positive DRE is an indication for prostate biopsy. The majority use a serum PSA level of 4 ng/ml as a cut-off value. A fluoroquinolone is the antibiotic of choice. Periprostatic nerve block is the commonest form of anaesthesia. Most urologists take 8-10 cores per biopsy.

Abstract
Lobular neoplasia (LN) is a risk factor for bilateral breast cancer without consensus as to its appropriate management. The authors report on a retrospective multi-institutional study concerning 52 patients in whom a diagnosis of LN was made after core needle biopsy (CNB) and who subsequently underwent surgical excision. The excision specimens revealed seven cases of invasive carcinoma and three cases of ductal carcinoma in situ, indicating an underestimation of lesions at CNB in 19% of cases, and in particular in those patients with pleomorphic LN, and when clinical, radiological masses were detected. This lesion is increasingly being diagnosed by CNB due to widespread screening. Follow-up surgical excision should be performed in order to examine the whole lesion in the case of masses or when the histologic specimen reveals a pleomorphic subtype. In other cases, annual mammographic surveillance should be undertaken due to the persistent long-term risk of developing bilateral breast cancer.
