Nonsuspicious prebiopsy multiparametric MRI: is prostate biopsy still necessary?

International audiencePurpose To evaluate the negative predictive value (NPV) of multiparametric magnetic resonance imaging (mpMRI), alone or combined with Prostate-Specific Antigen density (PSAd) to exclude clinically significant prostate cancer (csPCa). Patients and Methods We performed a retrospective chart review of all the patients who had transrectal ultrasound-guided biopsy (TRUSGB) in our center between January 2014 and March 2019. We included patients who had nonsuspicious prebiopsy mpMRI defined as Prostate Imaging-Reporting and Data System (PI-RADS) <= 2. MRI was performed using a 1.5 or 3-Tesla Magnetic Resonance scanners with external phased-array coil. The primary outcome was the detection of csPCa, defined as a Gleason score 3 + 4 (ISUP 2) or higher on at least one biopsy core. Results One hundred and ninety-one consecutive men (median age: 65 years, median PSA level: 9.3 ng/mL) underwent TRUSGB following negative prebiopsy mpMRI corresponding to 126 (66%) biopsy-naive patients, 36 (18.8%) patients with prior negative biopsy, and 29 (15.2%) patients under active surveillance with confirmatory biopsies. The overall PCa and csPCA detection rates were 26.7% and 5.2%, conferring a NPV of 73.3% and 94.8%, respectively. The NPV of negative mpMRI improved to 95.8% in patients with PSAd < 0.15 ng/mL/cm(3)and to 100% in patients with PSAd < 0.10 ng/mL/cm(3). Conclusions A negative prebiopsy mpMRI had an overall NPV of 94.8% for csPCa when mpMRI was used alone to 95.8% when combined with PSAd < 0.15 ng/mL/cm(3). Future studies are needed to balance the low benefit of a biopsy in this indication with the morbidity of the procedure

The prognostic value of serum procalcitonin in acute obstructive pyelonephritis

International audiencePurpose To evaluate the prognostic value of procalcitonin (PCT) in the occurrence of infectious complications in the management of acute obstructive pyelonephritis (AOP) compared with other biological parameters (leucocyte count, C-reactive protein [CRP]). Methods We conducted a retrospective study including patients who were treated for AOP and performed serum PCT tests in our center between January 1, 2017 and December 31, 2017. Upper urinary tract obstruction was confirmed by either ultrasound or CT urography. Clinical examinations and laboratory tests including leukocyte count, CRP, urine and blood cultures, and serum PCT measurements were performed in the emergency unit. Treatment included early renal decompression using indwelling ureteral stents or nephrostomy and empiric antibiotic therapy. The primary endpoint was occurrence of severe sepsis (SS), a composite criterion including urosepsis and/or septic shock and/or admission to the intensive care unit (ICU) and/or death. Results A total of 110 patients (median age: 61 years) were included, of whom 56.3% were female. SS occurred in 39 cases (35.4%). Multivariate regression analysis showed that serum PCT (OR 1.08; 95% CI 1.03-1.17;p = 0.01), CRP (OR 1.007; 95% CI 1.001-1.015;p = 0.03), and diabetes mellitus (OR 5.1; 95% CI 1.27-27.24;p = 0.04) were independent predictors for SS. Serum PCT was the biological marker associated with the highest accuracy to predict SS (ROC 0.912 (95% CI 0.861-0.962) and was superior to CRP (p 1.12 mu g/L could help physicians to identify high-risk patients who could benefit from early and aggressive management in collaboration with intensive care specialists

Efficacy and Safety of Surgery for Benign Prostatic Obstruction in Patients with Preoperative Urinary Catheter

International audienceInterventional radiology plays an important and increasing role in cancer treatment. Follow-up is important to be able to assess treatment success and detect locoregional and distant recurrence and recommendations for follow-up are needed. At ECIO 2018, a joint ECIO-ESOI session was organized to establish follow-up recommendations for oncologic intervention in liver, renal, and lung cancer. Treatments included thermal ablation, TACE, and TARE. In total five topics were evaluated: ablation in colorectal liver metastases (CRLM), TARE in CRLM, TACE and TARE in HCC, ablation in renal cancer, and ablation in lung cancer. Evaluated modalities were FDG-PET-CT, CT, MRI, and (contrast-enhanced) ultrasound. Prior to the session, five experts were selected and performed a systematic review and presented statements, which were voted on in a telephone conference prior to the meeting by all panelists. These statements were presented and discussed at the ECIO-ESOI session at ECIO 2018. This paper presents the recommendations that followed from these initiatives. Based on expert opinions and the available evidence, follow-up schedules were proposed for liver cancer, renal cancer, and lung cancer. FDG-PET-CT, CT, and MRI are the recommended modalities, but one should beware of false-positive signs of residual tumor or recurrence due to inflammation early after the intervention. There is a need for prospective preferably multicenter studies to validate new techniques and new response criteria. This paper presents recommendations that can be used in clinical practice to perform the follow-up of patients with liver, lung, and renal cancer who were treated with interventional locoregional therapies
