MRI-guided micro-US FLA shows potential for outpatient use, but its clinical application remains unexplored. Purpose To evaluate the safety, feasibility, and 12-month functional and oncologic outcomes of MRI-guided micro-US transperineal FLA in localized PCa and to assess the accuracy of micro-US in showing lesions depicted at MRI with Prostate Imaging Reporting and Data System (PI-RADS) score of 3 or higher. Materials and Methods This prospective, single-center observational study (July 2020 to June 2023) included participants with localized low- or intermediate-risk PCa and PI-RADS 3 or higher lesions (≤20 mm). Single- or multifiber FLA was performed at 1064 nm, guided by MRI-delineated image fusion. At 12 months, recurrence rates, complications, erectile function scores, and urinary symptom scores were assessed. Mann-Whitney <i>U</i> and Wilcoxon tests were used for comparisons. Results Fifty-five male participants (median age, 70 years; IQR, 62-74 years) with 58 lesions that were PI-RADS 3 or higher underwent transperineal FLA, with a 12-month follow-up for 33 participants. The median prostate-specific antigen level was 7.0 ng/mL (IQR, 5.6-9.0 ng/mL), 43 of 58 lesions (74%) had a Gleason score of 3 + 4, and 10 of 58 lesions (17%) had a Gleason score of 3 + 3. Single-fiber and multifiber FLA were used to treat 21 of 58 (36%) and 37 of 58 (64%) tumors, respectively. At micro-US, 53 of 58 (91%) tumors were successfully visualized. Multifiber FLA produced larger ablation volumes than did single-fiber treatment (median, 15 mL [IQR, 8-22 mL] vs 4.5 mL [IQR, 2.8-9.2 mL]; <i>P</i> < .001). At 12 months, biopsies in 35 treated tumors showed 17 recurrences (49%), including 13 in-field and four out-of-field recurrences. In-field recurrences occurred in 10 of 18 (56%) single-fiber and three of 17 (18%) multifiber cases. At 12 months, erectile function scores decreased compared with baseline (median International Index of Erectile Function score, 19 [IQR, 12-24] vs 21 [IQR, 15-24]; <i>P</i> < .001), whereas urinary function remained stable (median International Prostatic Symptom Score, 2 [IQR, 2-9] vs 6 [IQR, 3-11]; <i>P</i> = .72). One rectoprostatic fistula developed and required surgery. Conclusion Multifiber micro-US-guided FLA was safe and feasible, with 18% recurrence at 1-year follow-up. Clinical trial registration no.

However, with advances in the management of lung cancer, there is a need for a greater amount of tissue for tumor genomic profiling and characterization. Purpose To determine whether the number of core samples obtained with percutaneous CT-guided lung biopsy is associated with postprocedural complications. Materials and Methods This retrospective study included consecutive patients who underwent percutaneous CT-guided coaxial lung core-needle biopsy for suspected primary lung cancer between November 2012 and August 2023 at an academic tertiary referral hospital. Patient data from medical records were collected, including demographics, lesion size and distance from pleura, and number of obtained biopsy samples. Postprocedural complications of pneumothorax, chest tube placement, perilesional hemorrhage, and hemoptysis were recorded. Multivariable logistic regression models were used to assess whether the number of cores was a predictive factor for lung biopsy complications. Results A total of 827 patients (mean age, 70.9 years ± 9.6 [SD]; 474 [57.3%] female patients) were included. The median lesion size was 22 mm (IQR, 15-34 mm), with 517 of 827 (62.5%) patients diagnosed with lung adenocarcinoma. Pneumothorax was noted in 171 of 827 (20.7%) patients, with a chest tube placed in 32 of 827 (3.9%), perilesional hemorrhage in 353 of 827 (42.7%), and hemoptysis in 20 of 827 (2.4%) patients. The median number of samples obtained was four (range, one to 12). Multivariable analysis showed no evidence of an association between the number of core samples obtained and any complications: pneumothorax (coefficient, -0.02; <i>P</i> = .81), chest tube (coefficient, 0.18; <i>P</i> = .26), perilesional hemorrhage (coefficient, -0.03; <i>P</i> = .63), or hemoptysis (coefficient, -0.10; <i>P</i> = .60). Conclusion In patients suspected of having lung cancer who underwent percutaneous CT-guided coaxial lung core biopsy, there was no evidence of an association between the number of core biopsy samples obtained and any postprocedural complications. © RSNA, 2024 See also the editorial by Zuckerman in this issue.</p>","PeriodicalId":20896,"journal":{"name":"Radiology","volume":"313 2","pages":"e232168"},"PeriodicalIF":12.1,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142584103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
