Mapping Thyroid Changes in Size and Position during Enlargement in Adult Mice with Hyperthyroidism.

The thyroid in Graves' disease undergoes a considerable divergence in size and position from the normal anatomy. However, knowledge of the pathological anatomy related to the change, which is required before planned surgical or local intervention, or diagnosis, is neglected. To investigate Graves' disease, we well-established a model of mice that successfully mimics all the signs presented in the clinic. Under a long-term immunization (35 weeks), the animals displayed a big heterogeneity in thyroid size, like the cases of natural occurrence. These thyroids in the model were sized into various phases and registered. A blend of the registered thyroids and the thyroid and tracheal cartilage landmarks led to the production of site-dependent incidence graphs of thyroid in the front view and on the section for each phase. The merger of the incidence graphs of all the phases resulted in thyroid phase-dependent topography. The depicted graphs illustrate the fine localization of the thyroid in various sizes and their dynamic changes during enlargement, which may facilitate currently used fine-needle aspiration biopsy and ultrasonography-guided biopsy techniques. Familiarity with the knowledge might avoid misclassifying an abnormality as normal, or vice versa, and be helpful for imaging diagnosis and local surgery therapy in Graves' disease.

Gastric inflammatory myofibroblastic tumor: a case report

BackgroundInflammatory myofibroblastic tumor (IMT) of the stomach is an uncommon mesenchymal neoplasm. We present a case of gastric submucosal tumor (SMT) where the final diagnosis was IMT.Case presentationA 69-year-old man presented with a 24-mm SMT on the posterior wall of the middle third of the stomach that was detected by screening upper gastrointestinal endoscopy. Abdominal contrast-enhanced computed tomography showed that the tumor was well-enhanced. Although endoscopic ultrasonography-guided biopsy was performed, the histological diagnosis was not confirmed preoperatively. Since the tumor was clinically suspected to be a gastrointestinal stromal tumor, we performed gastric wedge resection by laparoscopic–endoscopic cooperative surgery. Pathologically, proliferative spindle cells with a positive reaction for smooth muscle actin, negativity for c-kit, desmin, s-100, CD34, STAT-6, β-catenin and anaplastic lymphoma kinase 1 were identified. Hence, the tumor was finally diagnosed as an IMT originating from the stomach.ConclusionsWhen an SMT of the stomach is identified, the possibility of gastric IMT should be considered.

Added value of randomised biopsy to multiparametric magnetic resonance imaging-targeted biopsy of the prostate in a contemporary cohort.

To assess the added value of concurrent systematic randomised ultrasonography-guided biopsy (SBx) to multiparametric magnetic resonance imaging (mpMRI)-targeted biopsy and the additional rate of overdiagnosis of clinically insignificant prostate cancer (ciPCa) by SBx in a large contemporary, real-world cohort. A total of 1552 patients with positive mpMRI and consecutive mpMRI-targeted biopsy and SBx were enrolled. Added value and the rate of overdiagnosis by SBx was evaluated. added value of SBx, defined as detection rate of clinically significant PCa (csPCa; International Society of Urological Pathology [ISUP] Grade ≥2) by SBx, while mpMRI-targeted biopsy was negative or showed ciPCa (ISUP Grade 1). rate of overdiagnosis by SBx, defined as detection of ciPCa in patients with negative mpMRI-targeted biopsy and PSA level of <10 ng/mL. Detection rate of csPCa by mpMRI-targeted biopsy and/or SBx was 753/1552 (49%). Added value of SBx was 145/944 (15%). Rate of overdiagnosis by SBx was 146/656 (22%). Added value of SBx did not change when comparing patients with previous prostate biopsy and biopsy naïve patients. In multivariable analysis, a Prostate Imaging-Reporting and Data System (PI-RADS) 4 index lesion (odds ratio [OR] 3.19, 95% confidence interval [CI] 1.66-6.78; P = 0.001), a PI-RADS 5 index lesion (OR 2.89, 95% CI 1.39-6.46; P = 0.006) and age (OR 1.05, 95% CI 1.03-1.08; P < 0.001) were independently associated with added value of SBx. In our real-world analysis, we saw a significant impact on added value and added rate of overdiagnosis by SBx. Subgroup analysis showed no significant decrease of added value in any evaluated risk group. Therefore, we do not endorse omitting concurrent SBx to mpMRI-guided biopsy of the prostate.

Histologic scoring of liver biopsies for the prognosis of chronic liver disease at a tertiary care hospital in South India

ObjectivesThe study aimed to evaluate the role of histologic scoring of liver biopsies using Ishak-modified histological activity index (HAI) and Laennec’s scoring system in predicting chronic liver disease (CLD) prognosis in South India. MethodsA retrospective analysis of liver biopsy samples was conducted at a tertiary care hospital. The samples were scored using the Ishak-modified HAI and Laennec’s scoring system for staging and grading CLD. Patient clinical data were retrieved and assessed using the Child-Pugh scoring system. Chi-squared test was used to test the association between categorical variables and the association with multiple categories was reported using Cramer’s V correlation coefficient. A p-value < 0.05 was considered significant. ResultsOut of 43 samples included in the study, 65.12% were male patients, with a mean age of 43.3 ± 13.9 years. Cirrhotic cases accounted for the highest proportion (65.12%, n = 28), followed by hepatitis cases (30%, n = 13). The predominant etiology was alcohol-related (44.19%, n = 19). Percutaneous liver biopsies constituted most of the samples (48.84%, n = 21), followed by transjugular (37.21%, n = 16) and ultrasonography-guided (11.63%, n = 6) biopsies. The correlation between Ishak-modified HAI stages and Child-Pugh scores was weak and insignificant (p = 0.71), while Laennec's scores showed a moderate but insignificant correlation with Child-Pugh scores (p = 0.066). ConclusionHistologic scoring of liver biopsies using the Ishak-modified HAI and Laennec's scoring system can provide valuable prognostic information for CLD. However, further research is needed to establish stronger correlations with clinical outcomes.

Comparative Prostate Cancer Detection Rate of Transrectal Ultrasonography Guided versus Finger Guided Prostate Biopsy

Background: Prostate biopsy was used to diagnose and establish a therapy for prostate cancer (PCa). Instead of using conventional finger-guided prostate biopsy (FGPB) to approximate prostatic architecture, transrectal ultrasonography-guided biopsies of the prostate (TRUSGB) have become more popular nowadays because of offer direct visualization. However, the lack of availability of transrectal ultrasound probes in less-developed regions raises concerns regarding the need to diagnose patients with PCa. Moreover, different conclusions have been found from prior studies that examined the efficacy of both methods. This study aims to compare the accuracy of TRUSGB to FGPB in prostate cancer.. Methods: This study was done retrospectively from 50 medical records of PCa in the Urology Division of Sardjito Hospital from January 2009 until December 2013. Patients’ age, PSA value, digital rectal examination, and histopathological examination were analyzed. Results: The mean age was 65.18 ± 7.76 years in FGPB and 67.52 ± 10.79 years in TRUSGB group. The median PSA was 65.01 (range: 16.33–114.72) ng/mL in FGPB and 71.75 (range: 19.86– 123.47) ng/mL in TRUSGB. Abnormal DRE was found in 75.75% of patients in FGPB group and 70.58% in TRUSGB. Comparable cancer detection rates were found in the FGPB and TRUSGB groups (45.45% vs. 52.94%) (p = 0.136).Conclusions: The cancer detection rates for FGPB and TRUSGB procedures are comparable. This supports using FGPB as the first-line diagnostic technique, especially in low-resource situations where ultrasonography is unavailable.

Expression changes of Tim-3 as one of supplementary indicators for monitoring prognosis of liver pathological changes in chronic HBV infection

PurposeThis study was designed to analyze the liver tissue changes among the CHB patients who received treatment for at least 6 months and follow-up for at least 1 year, together with the correlation between the different disease condition and serum markers.MethodsOne-hundred and eighty-five CHB patients underwent antiviral therapy for at least 6 months were enrolled. In the 12-month follow-up, ultrasonography-guided biopsy was performed. The patients were grouped based on the serum markers and pathological changes in liver tissues. Then we determined the serum markers, virological tests and Tim-3 expression among these groups.ResultsAntiviral therapy significantly reduced liver inflammation indicators and serum Tim-3 level. However, the fibrosis process of liver tissue was not changed, and there are still disputes on the serum marker and hepatic lesion outcomes. Under normal liver function or negative hepatitis B e antigen (HBeAg) of CHB patients, there might be consensus between Tim-3 change and liver pathological outcome. According to the liver tissue inflammation and fibrosis conditions, Tim-3 was positively correlated with liver function indices. Besides, it was also related to fibrosis stage and inflammation grade.ConclusionThere were inconsistent changes between serum markers and liver tissue conditions after anti-viral therapy. Tim-3 expression was more suitable to indicate the changes of liver inflammatory and fibrosis response to some extent than ALT and AST. It may serve as a certain indicator to predict the CHB prognosis, which could be used as one of the monitoring indicators in liver pathological changes of chronic HBV infection, especially in monitoring liver tissue inflammation.

A Review On Artificial Intelligence For Thyroid Nodule Ultrasound

Ultrasound is a versatile green imaging modality that is rapidly gaining traction as a first-line imaging tool in a variety of clinical settings, thanks to the ongoing development of sophisticated ultrasonic technology and the well-established Ultrasound-based digital health system. Thyroid nodules are tumours that are mostly benign, but can can be malignant and invasive malignancies. These tumours are curable and become more common as people get older. The size and ultrasound features are used to determine whether or not an ultrasonography-guided biopsy should be performed. The American Thyroid Association's thyroid nodule recommendations count the number of benign or suspicious ultrasonography findings before recommending biopsy or observation depending on the size of the nodule.

Detection of mecA and 16S rRNA Genes Using Real-Time PCR Can Be Useful in Diagnosing Iliopsoas Abscess, Especially in Culture-Negative Cases: RT-PCR for Iliopsoas Abscess.

The rapid detection of etiological agents is important for the successful treatment of iliopsoas abscess (IPA). The purpose of this study was to investigate the clinical utility of a real-time polymerase chain reaction (PCR) that targets the mecA gene for methicillin-resistant staphylococci (MRS) and the 16S rRNA gene for pan-bacteria. Our retrospective diagnostic study included 22 patients exhibiting IPAs and four patients with noninfectious iliopsoas mass regions who underwent computerized tomography or ultrasonography-guided biopsy and/or surgical treatment. Clinical symptoms, serum data, imaging analysis, and tissue microbiological culture were utilized for the diagnosis of IPA. The diagnostic accuracy of real-time PCR was determined based on the diagnosis of IPA and microbiological culture results. The microbiological culture was positive for 12 IPA cases that included 2 MRSA infections. Among 12 culture-positive IPA cases, 16S rRNA-PCR was positive in 12 and MRS-PCR in two. Among 10 culture-negative IPA cases, including 3 TB cases, 16S rRNA-PCR was positive in 8 and MRS-PCR in 2. In noninfectious iliopsoas mass patients, neither 16S rRNA nor MRS-PCR detected bacterial DNA. The sensitivity, specificity, positive predictive, and negative predictive values of 16S rRNA-PCR for diagnosing IPA were 0.91, 1.00, 1.00, and 0.67, respectively, while those for the diagnosis of MRS infection with MRS-PCR were 1.00, 0.92, 1.00, and 0.50, respectively. Real-time PCR targeting bacterial DNA can detect bacterial DNA in culture-negative cases and offer improved detectability of MRS infection in IPA patients.

Effect of ultrasound use on the pathological outcomes in temporal artery biopsy

Aim:This study aimed to determine whether there is a significant difference between the results of a standard biopsy and Doppler ultrasonography-guided biopsy of the temporal artery, which showed low preoperative pulse pressure.&#x0D; Material and Methods: Data from 21 patients, who received preliminary diagnosis of temporal arteritis at the neurology clinic were retrospectively investigated. Patients were divided into two groups depending on the method with Doppler ultrasonography and without ultrasonography.&#x0D; Results: Results from a total of 21 patients were evaluated. The first group consisted of 11 patients who underwent standard temporal artery biopsy, while the second group consisted of 10 patients who underwent ultrasonography-guided biopsy. Six patients in the group without the ultrasonography guidance showed insignificant results. Furthermore, the samples were insufficient in four of these six patients. In contrast, four patients from the Doppler ultrasonography-guided group were diagnosed with arteritis, in addition to the fact that an insufficient biopsy sample was not encountered in these patients.&#x0D; Statistical analysis showed that there was no significant difference between the pathology results of the two groups.&#x0D; Conclusion: Although we failed to find a significant difference between the groups, we believe that the Doppler ultrasonography-guided biopsy should be used as a supportive tool rather than diagnostic tool per se, as the Doppler ultrasonography-guided group did not provide insufficient biopsy samples in the pathology results as opposed to the standard group.

Is PSA density of the peripheral zone as a useful predictor for prostate cancer in patients with gray zone PSA levels?

BackgroundSerum prostate-specific antigen (PSA) is widely used in screening tests for prostate cancer. As the low specificity of PSA results in unnecessary and invasive prostate biopsies, we evaluated the clinical significance of various PSAs and PSA density (PSAD) related to peripheral zones in patients with gray zone PSA level (4–10 ng/mL).MethodsA total of 1300 patients underwent transrectal ultrasonography-guided prostate biopsy from 2014 to 2019. Among them, 545 patients in the gray zone were divided into the prostate cancer diagnosis group and the non-prostate cancer diagnosis group, and PSA, relative extra transitional zone PSA (RETzPSA), estimated post holmium laser enucleation of the prostate PSA (EPHPSA), PSAD, peripheral zone PSA density (PZPSAD) and extra-transitional zone density (ETzD) were compared and analyzed using receiver-operating characteristics (ROC) analysis after 1:1 matching using propensity score.ResultsArea under the ROC curve values of PSA, EPHPSA, RETzPSA, PSA density, ETzD, and PZPSAD were 0.553 (95% CI: 0.495–0.610), 0.611 (95% CI: 0.554–0.666), 0.673 (95% CI: 0.617–0.725), 0.745 (95% CI: 0.693–0.793), 0.731 (95% CI: 0.677–0.780) and 0.677 (95% CI: 0.611–0.719), respectively. PSAD had 67.11% sensitivity, 71.71% specificity, and 70.34% positive predictive rate at 0.18 ng/mL/cc. ETzD had 69.08% sensitivity, 64.47% specificity, and 66.04% positive predictive rate at 0.04 ng/mL/cc. When the cut-off value of PSAD was increased to 0.18 ng/mL/cc, the best results were obtained with an odds ratio of 5.171 (95% CI: 3.171–8.432), followed by ETzD with 4.054 (95% CI: 2.513–6.540).ConclusionsThese results suggested that volume-adjusted parameters (ETzD and PSAD) might be more sensitive and accurate than various PSA in gray zone patients who required prostate biopsy to reduce unnecessary biopsy.

For men enrolled in active surveillance, pre-biopsy biparametric magnetic resonance imaging significantly reduces the risk of reclassification and disease progression after 1 year

Aims To assess the level of disease progression at confirmatory staging biopsies after 1 year of active surveillance (AS) and compare the detection rate of significant prostate cancers (PCas) in patients who underwent pre-biopsy biparametric magnetic resonance imaging (bpMRI) before the first set of diagnostic transrectal ultrasonography-guided biopsies (TRUS-bx) with the detection rate in patients who did not undergo pre-biopsy bpMRI. Materials and methods Comparison of two patient groups enrolled in AS. Patients in Group A (n = 127) underwent pre-biopsy bpMRI followed by TRUS-bx ± targeted biopsies. Patients in Group B (n = 127) were enrolled in AS based on biopsy results from TRUS-bx only. Results Overall, 6% of the patients in Group A and 20% of the patients in Group B had an upgrade in Gleason grade from insignificant to significant PCa at confirmatory staging biopsies (odds ratio [OR], 3.5; p = .002; 95% confidence interval [CI], 1.6–7.9). Conclusions Patients who underwent pre-biopsy bpMRI before the first set of diagnostic biopsies had a reduced risk of reclassification and disease progression after 1 year of AS. Thus, pre-biopsy bpMRI improves the selection of men who should be enrolled in AS.

Intraprostatic prophylactic antibiotic injection in patients undergoing transrectal ultrasonography-guided prostate biopsy.

To evaluate the efficacy of intraprostatic injection of prophylactic antibiotics for the prevention of infections following transrectal ultrasonography-guided prostate biopsy. In this prospective interventional study, patients aged between 40 and 70years with clinical indications for transrectal ultrasonography-guided prostate biopsy were enrolled. Consecutive patients who received intraprostatic injection of amikacin coupled with oral ciprofloxacin were compared with historical controls receiving only prophylactic oral fluoroquinolones prior to biopsy. Patients were followed for 7days after biopsy for signs and symptoms of infection. A total of 210 patients were included in this study (mean age 65.7±7.8years). Among patients without intraprostatic injection, nine (8.6%) developed infectious complications (lower urinary tract infection in seven patients, and prostatitis in two), which led to hospitalization in six patients (5.7%). None of the patients who received intraprostatic antibiotic injection developed infectious complications. The difference in the incidence of post-transrectal ultrasonography-guided biopsy infections between the two groups was statistically significant (P=0.003). Local intraprostatic antibiotic injection during transrectal ultrasonography-guided prostate biopsy adjuvant to oral fluoroquinolones can significantly reduce the rate of post-biopsy infectious complications.

Evaluation of multiparametric prostate magnetic resonance imaging findings in patients with a Gleason score of 6 in transrectal ultrasonography-guided biopsy.

PurposeWe aimed to evaluate prostate multiparametric magnetic resonance imaging (mpMRI) findings of patients with a Gleason score (GS) of 6 and effectiveness of MRI based on the final pathology result in patients undergoing radical prostatectomy (RP).Material and methodsmpMRI findings of 80 patients who had a GS of 3 + 3 and who underwent mpMRI were evaluated retrospectively. The mpMRI were scored according to the PIRADS v2.1 guidelines. The patients were divided into those with a high probability of clinically significant cancer (CSC) (PI-RADS 4-5) and those with a low probability of CSC (PI-RADS 2-3).ResultsOf the 80 patients, 33.8% had PI-RADS 2-3, and 66.2% had PI-RADS 4-5 lesions. There was a significant difference between the groups in prostate specific antigen (PSA) value, PSA density, patient age, and tumour percentage on biopsy. When the pathology results were taken as the gold standard in the group that underwent RP, sensitivity, specificity, and accuracy of mpMRI were calculated as 94.74%, 100%, and 96.3%, respectively, an increase in the final GS was found in 9 (33.3%) of the 27 patients, and 70.35% of patients were identified as having CSC.ConclusionsPI-RADS 4-5 scores have high sensitivity and negative predictive value in the diagnosis of CSC. mpMRI is a reliable and non-invasive diagnostic method that can complement biopsy results in decision-making in patients who are initially evaluated as low risk.

Pre-aspiration of a large retention cyst followed by EUS-FNB for the successful diagnosis of a patient with pancreatic cancer.

Endoscopic ultrasonography-guided fine needle biopsy is an indispensable tool for the diagnosis of pancreatic tumors but is occasionally difficult to perform owing to cystic lesions that intervene with the puncture route. Yamamoto and colleagues recommend a pre-aspiration technique in patients with pancreatic cancer and a retention cyst in the puncture route.

Carcinoma prostate with intradural metastasis: A case report and review of the literature on a rare entity with dismal prognosis

Prostate carcinoma is the second most common cancer in men. While bone metastasis is more common in carcinoma prostate, dural metastasis is an uncommon diagnosis. Nowadays, men with castration-resistant prostate cancer (CRPC) have shown increase survival with the introduction of better chemotherapy regimens. Here, we present the case of a heavily pre-treated CRPC patient of age 69-year-old who developed metastasis to dura mater. The patient presented with complaints of increased urinary frequency and urgency with bilateral inguinal lymphadenopathy. The ultrasonography-guided biopsy showed acinar adenocarcinoma of the prostate with a Gleason score of 4 + 4 = 8 and TNM staging of T1N3M1b. He was treated initially with hormonal therapy. Subsequently, he developed castration resistance and was advised docetaxel-based chemotherapy. However, on follow-up, the patient developed dural metastasis. Metastases to dura mater should be considered as a differential diagnosis in advanced CRPC with neurological symptoms.

Recurrent broad ligament leiomyosarcoma with pancreatic and thigh metastasis: a case report

BackgroundLeiomyosarcoma (LMS) is an uncommon mesenchymal neoplasm, which infrequently metastasizes to pancreas and thigh. Clinical presentation and imaging findings of metastatic broad ligament LMS are often nonspecific. Complete excision plays an important role in treatment of patients with localized LMS.Case presentationHere, we report a case of a 33-year-old woman with recurrent broad ligament LMS metastasizing to pancreas and thigh. Previously, she was diagnosed with broad ligament LMS and underwent hysterectomy, bilateral salpingo-oophorectomy. The disease-free interval was 2.5 years until metastases were found. Computerized tomography (CT) of abdomen and thighs, magnetic resonance imaging (MRI) of thighs and whole-body 18-fluorodeoxyglucose positron emission tomography - computed tomography (PET-CT) performed, revealed pancreatic and thigh metastasis. Ultrasonography-guided biopsy and histological examinations confirmed LMS at both the sites. Pancreatic metastasis was completely resected first. Then the patient underwent surgical resection of thigh metastasis when both chemotherapy and radiotherapy failed. She recovered well and remained free of disease recurrence in the 2 years follow-up.ConclusionsThough imaging lacks specificity, it is a valuable asset in assessing the burden of disease and characterizing lesions while histological examination with immunohistochemistry is helpful for the diagnosis of LMS. Complete surgical resection of all metastatic sites where-ever feasible should be strongly considered in a treated case of broad ligament LMS with a durable disease-free interval.

Biparametric versus multiparametric magnetic resonance imaging of the prostate: detection of clinically significant cancer in a perfect match group.

BackgroundBiparametric (bp) magnetic resonance imaging (MRI) could be an alternative MRI for the detection of the clinically significant prostate cancer (csPCa).PurposeTo compare the accuracies of prostate cancer detection and localization between prebiopsy bpMRI and postbiopsy multiparametric MRI (mpMRI) taken on different days, using radical prostatectomy specimens as the reference standards.Material and methodsData of 41 total consecutive patients who underwent the following examinations and procedures between September 2015 and March 2017 were collected: (1) magnetic resonance– and/or ultrasonography-guided biopsy after bpMRI; (2) postbiopsy mpMRI; and (3) radical prostatectomy with csPCa. Two radiologists scored suspected lesions on bpMRI and mpMRI independently using Prostate Imaging Reporting and Data System version 2. The diagnostic accuracy of detecting csPCa and the Dice similarity coefficient were obtained. Apparent diffusion coefficient (ADC) ratios were also obtained for quantitative comparison between bpMRI and mpMRI.ResultsDiagnostic accuracies on bpMRI and mpMRI were 0.83 and 0.82 for reader 1; 0.80 and 0.82 for reader 2. There are no significantly different values of diagnostic sensitivities or specificities between the readers or between MRI protocols. Intra-observer Dice similarity coefficient was significantly lower in reader 2, compared to that in reader 1 between the two MRI protocols. The range of mean ADC ratio was 0.281–0.635. There was no statistically significant difference in the ADC ratio between bpMRI and mpMRI.ConclusionsDiagnostic performance of bpMRI without dynamic contrast enhancement MRI is not significantly different from mpMRI with dynamic contrast enhancement MRI in the detection of csPCa.

A long-term survivor of recurrent esophagogastric junction adenocarcinoma treated with multidisciplinary therapy: a case report

BackgroundPatients with esophagogastric junction cancer are increasing in Western and Eastern countries. Conversely, the clinical significance of surgical resection remains controversial in these patients. We report a long-term survivor of recurrent esophagogastric junction adenocarcinoma who underwent constructive multimodal therapy, including surgical resection.Case presentationA 51-year-old man underwent total gastrectomy for esophagogastric junction adenocarcinoma in 2009. In June 2010, computed tomography (CT) indicated a lung nodule and we partially resected the right lower lung. It was pathologically diagnosed as distant metastasis from esophagogastric junction cancer. After lung resection, he received adjuvant chemotherapy with S-1 for 1 year. In September 2014, CT demonstrated a swelling of the upper mediastinal lymph node with abnormal uptake on fluorine-18 fluorodeoxyglucose positron emission tomography. We performed an ultrasonography-guided needle biopsy, and he was diagnosed with lymph nodal recurrence of esophagogastric junction adenocarcinoma by pathological examination and was subsequently treated with capecitabine plus cisplatin plus trastuzumab. Since CT showed a reduction in the metastatic upper mediastinal lymph node after chemotherapy, he underwent upper mediastinal lymphadenectomy in April 2015. Following surgery, we provided radiation therapy to the upper mediastinum and chemotherapy with S-1. At the last report, the patient was alive for 8 years and 3 months since the first surgery.ConclusionsThis case report shows the clinical benefit of constructive multimodal therapy for recurrent esophagogastric junction adenocarcinoma.

Added value of diffusion-weighted images and dynamic contrast enhancement in multiparametric magnetic resonance imaging for the detection of clinically significant prostate cancer in the PICTURE trial.

To determine the additional diagnostic value of diffusion-weighted imaging (DWI) and dynamic contrast-enhanced imaging (DCE) in men requiring a repeat biopsy within the PICTURE study. PICTURE was a paired-cohort confirmatory study in which 249 men who required further risk stratification after a previous non-magnetic resonance imaging (MRI)-guided transrectal ultrasonography-guided biopsy underwent a 3-Tesla (3T) multiparametic (mp)MRI consisting of T2-weighted imaging (T2W), DWI and DCE, followed by transperineal template prostate mapping biopsy. Each mpMRI was reported using a LIKERT score in a sequential blinded manner to generate scores for T2W, T2W+DWI and T2W+DWI+DCE. Area under the receiver-operating characteristic curve (AUROC) analysis was performed to compare the diagnostic accuracy of each combination. The threshold for a positive mpMRI was set at a LIKERT score ≥3. Clinically significant prostate cancer was analysed across a range of definitions including UCL/Ahmed definition 1 (primary definition), UCL/Ahmed definition 2, any Gleason ≥3 + 4 and any Gleason ≥4 + 3. Of 249 men, sequential MRI reporting was available for 246. There was a higher rate of equivocal lesions (44.6%) using T2W alone compared to the addition of DWI (23.9%) and DCE (19.8%). Using the primary definition of clinically significant disease, there was no significant difference in the overall accuracy between T2W, with an AUROC of 0.74 (95% confidence interval [CI] 0.68-0.80), T2W+DWI at 0.76 (95% CI 0.71-0.82), and T2W+DWI+DCE, with an AUROC of 0.77 (95% CI 0.71-0.82; P = 0.55). The AUROC values remained comparable using other definitions of clinically significant disease including UCL/Ahmed definition 2 (P = 0.79), Gleason ≥3 + 4 (P = 0.53) and Gleason ≥4 + 3 (P = 0.53). Using 3T MRI, a high level of diagnostic accuracy can be achieved using T2W as a single parameter in men with a prior biopsy; however, such a strategy can lead to a higher rate of equivocal lesions.

Magnetic resonance imaging diagnosis of prostate cancer: promise and caution.

KEY POINTS Among solid-organ tumours, prostate cancer is alone in being diagnosed via a nontargeted biopsy approach. Systematic transrectal ultrasonography-guided biopsy has been the standard of care to detect clinically important prostate cancer since 1989.[1][1] Yet modern image acquisition and
