Abstract
Introduction Prostate-specific membrane antigen (PSMA) positron emission tomography/ computed tomography (PET-CT) is widely used as a staging tool for patients with prostate cancer (PCa). The objective of the study is to assess the diagnostic accuracy of 68Ga-PSMA-PET/CT for PCa, which may help us avoid unnecessary biopsies in patients with intermediate prostate-specific antigen (PSA) levels. Material and methods In this prospective study, 81 patients suspected of PCa, with either raised PSA between 4-20 ng/ml or abnormal digital rectal examination (DRE) findings were included. 68Ga-PSMA-PET/CT was performed for all patients followed by transrectal ultrasound (TRUS) guided prostate biopsy. SUVmax (maximum standardized uptake value) was measured and correlated with biopsy results. Results Out of 81 patients, 31 (38.3%) patients were found to have malignancy on biopsy. Median SUVmax of biopsy positive patients was 10.4 (IQR 6.5-16.1) and biopsy negative patients (n=50) was 3.5 (IQR 1-4.9), (p <0.001). At a cut-off of 6.15, 68GA-PSMA-PET/CT demonstrated sensitivity of 84%, specificity of 80%, positive predictive value of 72.2%, negative predictive value of 88.9% and accuracy of 81.5% with an AUC of 0.876 (95% CI: 0.799-0.953, p <0.001). Conclusions The 68Ga-PSMA-PET/CT helps to localize suspicious lesions and improving the detection of primary prostate cancer. Our findings indicate a significant correlation of SUVmax values with biopsy results. We were also able to determine a cut-off value of SUVmax below which prostate biopsy can be avoided in selected patients.

Abstract
OBJECTIVE This study aimed to evaluate the predictors for positive biopsy in prostate cancer (PCa) patients and develop a risk-stratification score model for positive biopsy rate in patients with prostate specific antigen (PSA) in the gray zone. METHODS In this retrospective, multicenter, real-world study, Chinese patients receiving prostate biopsy for the first time were included. The study evaluated the positive biopsy rate, predictors for positive biopsy and a risk prediction model for PSA 4-10 ng/mL PCa was developed. The univariate and multivariate logistic regression analyses were used to identify the risk factors. RESULTS A total of 2426 patients were included in the study. The biopsy positive rate was 47.57%, 25.77%, and 60.57% among overall patients, total PSA (t-PSA) 4-10 ng/mL patients, and PSA > 10 ng/mL patients respectively. Elderly age 60-74, ≥75, multi parametric magnetic resonance imaging (MP-MRI), pre-operative PSA > 10 and PSA density (PSAD) significantly increased the positive rate in overall population, and elderly age, MP-MRI, positive digital rectal examination and f-PSA were significant predictors for positive biopsy in PSA 4-10 ng/mL population. A risk prediction model for positive biopsy rate in patients with PSA in the gray zone was developed. Area under curve (AUC) was associated with low accuracy for all the variables used such as tPSA (0.53), PSAD (0.57), frequency of puncture (0.53) and MP-MRI (0.64) in prediction of biopsy positive rate. CONCLUSION Our study evaluated the significant predicative factors for positive biopsy and the PCa risk prediction model developed might help Clinicians to avoid unnecessary biopsy in patients with PSA in gray zone.

Abstract
BACKGROUND Prostate cancer is the second most common cancer in men and sixth leading cause of mortality. If not recognized early, patients with advanced prostate cancer can experience debilitating complications which can otherwise be prevented by early androgen deprivation therapy. This research intends to define clear diagnostic tools that will guide practitioners in the rural community setting toward early management of advanced prostate cancer. METHODS We conducted a cross-sectional observational study at three referral hospitals in Kigali, Rwanda on patients who presented with clinical suspicion of advanced prostate cancer over a period of 6 months. All patients underwent prostate biopsy as well as metastatic work up (CT or MRI), for those who were eligible. Statistical analysis was done using STATA 14.2. RESULTS 114 patients were included in the study. The median age was 70 years (interquartile range: 65-79 years). In total 14 (12.3%) patients were found to have benign disease, while 100 (87.7%) patients were found to have cancer. Among those who had cancer, 85 (85%) had advanced prostate cancer. 110/114 (96.5%) were symptomatic at presentation. Common presenting symptoms were lower urinary tract symptoms (80.7%), back pain (54.4%), and urinary retention (36.8%). Abnormal digital rectal examination (DRE) was a strong risk factor for both cancer and advanced disease. Prostate cancer was found in 92.2% of those with abnormal DRE compared to 41.7% in those with normal DRE (p = 0.001). Also, cancer was found in 96.1% of those with multinodular prostate on DRE (p = 0.02) and had high odds (OR 14.6; CI 3.41-62.25) of having advanced prostate cancer (p < 0.001). The mean (± SD) PSA was 643.3 ± 1829.8 ng/ml and the median (range) was 100 ng/ml (9.05-10,000 ng/ml) for the whole study population. All patients with prostatic-specific antigen (PSA) of 100 ng/ml or above had advanced prostate cancer. CONCLUSION The results show that there is a significant correlation between clinical findings and advanced prostate cancer. All patients with abnormal DRE and PSA above 100 ng/ml had advanced prostate cancer. Diagnosis of advanced prostate cancer is possible at the community level if PSA testing is utilized and practitioners are well trained.

Abstract
BACKGROUND/PURPOSE To investigate the clinical presentation and survival outcomes of patients with both a high prostate-specific antigen (PSA) value and non-metastatic prostate cancer (PC). METHODS In total, 2053 PC patients were managed in our institute between January 2008 and December 2014. A total of 343 (16.7%) patients who presented with PSA values > 100 ng/mL were enrolled. Non-metastatic and metastatic PC were identified in 67 (group 1) and 276 (group 2) patients, respectively. Furthermore, 75 metastatic PC patients with PSA values < 20 ng/mL were included (group 3) for comparison. All demographics and survival outcomes were retrospectively reviewed by a questionnaire. RESULTS Group 2 patients had a higher PSA level than did group 1 (median: 1095 vs. 283 ng/mL, p < 0.001), and a higher Gleason grade than did groups 1 and 3 (grade group 4 plus 5: 60%, 77%, and 56%, for groups 1, 2, and 3, respectively; p < 0.001). Other demographics were similar among groups. Group 1 patients survived significantly longer than group 2 and 3 in terms of overall and cancer-specific survival rates (5-year overall survival rates: 87.5%, 46.3%, and 66.9%; 5-year cancer-specific survival rates: 94.7%, 52.7%, and 68.7% for groups 1, 2, and 3, respectively). Group 1 patients receiving local definitive treatments, such as radiation therapy or cryoablation, received survival and metastasis-free benefits compared to those without local treatment. CONCLUSION Patients with a high PSA value were not destined to have metastatic PC. Non-metastatic PC patients with a high PSA level obtained a survival benefit from local prostate-definitive treatments.

Abstract
BACKGROUND Given the potential complications of prostate biopsies, it is sometimes reasonable in selected patients to make a non-tissue diagnosis of prostate cancer. Little is known about prevalence and factors associated with non-tissue prostate cancer diagnoses in the United States. METHODS We identified 40 to 99-year-old prostate cancer patients with prostate specific antigen (PSA) ≥20 ng/ml from the 2010-2015 National Cancer Database. Associations were examined between non-tissue prostate cancer diagnosis and age, race, clinical T (cT) and M (cM) categories, PSA, and Charlson-Deyo Comorbidity Index (CCI) with multivariable analyses. RESULTS Among 62,635 patients, 6.2% had a non-tissue diagnosis. The proportion of patients with non-tissue diagnoses increased with advanced age (from 0.9% in ages 40-49 to 44.0% in ages 90-99) and disease stage (cT and cM) and higher CCI and PSA level. Demographic and clinical characteristics statistically significantly associated (all P < .001) with non-tissue diagnosis in adjusted analyses were older age (OR = 24.24, 90 to 99 vs. 60 to 69 years), and higher cT (OR = 4.83; T4 vs. T1), cM (OR = 5.25, M1C vs. M0), CCI (OR = 2.07; 3+ vs. 0), and PSA levels (OR = 3.19, >97.9 ng/ml vs.20 to 39 ng/ml), as well as hormonal therapy (OR = 0.51, with vs. without). CONCLUSIONS Non-tissue diagnosis of prostate cancer, while rare, is not outside normal clinical practice and is strongly associated with advanced patient age, higher clinical stage, multiple comorbidities, and very high PSA levels.

Abstract
Even though more than 350,000 men die from prostate cancer every year, broad-based screening for the disease remains a controversial topic. Guidelines demand that the only commonly accepted screening tool, prostate-specific antigen (PSA) testing, must be followed by prostate biopsy if results are elevated. Due to the procedure’s low positive predictive value (PPV), however, over 80% of biopsies are performed on healthy men or men with clinically insignificant cancer—prompting calls for new ways of vetting equivocal PSA readings prior to the procedure. Responding to the challenge, the present study investigated the diagnostic potential of tumour-associated circulating endothelial cells (tCECs), which have previously been described as a novel, blood-based biomarker for clinically significant cancers. Specifically, the objective was to determine the diagnostic accuracy of a tCEC-based blood test to detect clinically significant prostate cancer (defined as Gleason score ≥ 3 + 4) in high-risk patients. Performed in a blinded, prospective, single-centre set-up, it compared a novel tCEC index test with transrectal ultrasound-guided biopsy as a reference on a total of 170 patients and found that a tCEC add-on test will almost double the PPV of a standalone PSA test (32% vs. 17%; p = 0.0012), while retaining a negative predictive value above 90%.

Abstract
Objective: This study aimed to compare the differences in the clinical features of prostate cancer (PC) bone metastases (PCBMs) with and without extraosseous soft-tissue masses (ESTMs). Methods: Among 720 consecutive patients with histopathologically or clinically diagnosed PC, PCBMs were identified in 48 (7%) patients at initial diagnosis before receiving treatment. CT images of PCBMs were assessed and classified into two groups: PCBMs with and without ESTMs. Clinical features of PCBMs with and without ESTMs were compared. Results: We found ESTMs in 15 (31%) patients diagnosed with PCBMs, and 33 (69%) patients diagnosed with PCBMs did not have ESTMs. The initial prostate-specific antigen (PSA) levels (median, 1031 vs 247 ng ml−1; p < 0.05) and PSA reduction rates (median, 99.97 vs 99.40 %; p < 0.05) were significantly greater in PCBMs with ESTMs than in PCBMs without ESTMs. No significant differences were observed in terms of age, Gleason sum score, PSA nadir, time from the initiation of therapy to PSA nadir, PSA doubling time, PSA progression-free survival, or overall survival between patients having PCBMs with and without ESTMs. Conclusion: Both initial PSA levels and PSA reduction rates were higher in PCBMs with ESTMs than in PCBMs without ESTMs; however, no significant differences were observed in other clinical features. Advances in knowledge: ESTMs in patients with PCBMs were not a poor prognostic factor.

Abstract
PURPOSE To assess the diagnostic performance of 68Ga-PSMA PET/CT for detecting suspected prostate cancer (PCa) and to compare it with that of two cancer-predicting nomograms. METHODS We performed a retrospective analysis of 146 consecutive patients with suspected PCa based on symptoms or elevated total prostate-specific antigen (tPSA) levels who underwent 68Ga-PSMA PET/CT and histopathologic examinations from April 2017 to April 2018 in a large tertiary care hospital in China. The 68Ga-PSMA PET/CT results (PCa or benignancy) were evaluated by two experienced nuclear medicine specialists. The risk of positive PCa was evaluated using ERSPC and PCPT nomograms. The diagnostic performances of 68Ga-PSMA PET/CT and that of the two nomograms were compared via receiver operating characteristic (ROC) curve analysis, decision curve analysis, and logistic regression. RESULTS A total of 58 patients with tPSA of 0.4-50 ng/ml were included in the final analysis; PCa diagnosis was confirmed in 37 patients and excluded in 21 patients. ROC analysis showed that the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of 68Ga-PSMA PET/CT were 91.67, 81.82, 89.19, and 85.71%, respectively, in per-patient analyses. 68Ga-PSMA PET/CT exhibited a higher AUC (0.867) than those of ERSPC-RC3 (0.855) and PCPT-RC (0.770). The net benefit of 68Ga-PSMA PET/CT was greatest for patients within threshold probabilities of 15-90%. Among the 58 patients, 11 (19%) biopsies suggested by ERSPC-RC3 were unnecessary and could have been avoided if judged by the 68Ga-PSMA PET/CT results. Multivariate analysis revealed that the maximum standardised uptake value (SUVmax) and prostate volume were significant predictive factors for positive PCa results. CONCLUSION In suspected PCa patients with tPSA of 0.4-50 ng/ml, 68Ga-PSMA PET/CT outperformed the nomograms in predicting cancer and reducing unnecessary biopsies. In addition, the risk of PCa was positively correlated with a higher SUVmax and lower prostate volume, which could help clinicians in making preliminary estimates of individual cancer risk, monitoring 68Ga-PSMA PET/CT false-positive results and making biopsy decisions in daily medical practice.

Abstract
Acquired factor VIII deficiency (acquired hemophilia A) is a rare condition characterized by the acquisition of autoantibodies that affect the clotting activity of factor VIII (fVIII). The most common manifestation in affected patients is a hemorrhagic diathesis. This disorder is associated with autoimmune diseases, pregnancy, postpartum period, drugs, and malignancy. Management of this condition begins with attempts to arrest an acute bleed based on the site and severity of bleeding and inhibitor titer. The next priority is eradication of the fVIII antibodies using immunosuppressive therapies. We report the case of a 66-year-old male who presented with spontaneous right thigh hematoma with prolonged activated partial prothrombin time and normal prothrombin time. Mixing studies confirmed the presence of an inhibitor. Further investigation for the underlying etiology of acquired hemophilia A leads to diagnosis of prostate cancer. Treatment consisted of bypassing agents including activated factor VII and activated prothrombin plasma concentrate to arrest the bleeding. Steroids and cyclophosphamide were added to suppress the fVIII inhibitors. Concomitant treatment of locally advanced prostate cancer with chemotherapy confirmed the eradication of the inhibitors. To our knowledge, this is the first reported case of prostate cancer diagnosed and treated simultaneously with acquired hemophilia A resulting in favorable patient outcome.

Abstract
PURPOSE Prostate-specific antigen (PSA) is a useful biomarker of prostate cancer (PCa). High-risk localized PCa is defined using T stage, Gleason score (GS), and PSA. However, PSA level defining high-risk PCa is at most 20 ng/mL. In PCa patients with high PSA, it is unclear whether PSA itself can be a prognostic factor. METHODS Of 642 patients who were diagnosed as PCa, 90 patients with PSA > 100 ng/mL were retrospectively analyzed. Patients were divided into three groups according to PSA level: very high (>1,000 ng/mL), moderately high (200-1,000 ng/mL), and slightly high (100-200 ng/mL). RESULTS There were no significant differences in overall survival or PCa-specific survival (PCaSS) among the three groups. Regardless of PSA level, high M stage and GS significantly reduced PCaSS. When the risk classification was made using M stage and GS (high risk = M1 and GS ≥ 9, low risk = M0 and GS < 9, and intermediate risk = others), PCaSS was significantly different among high-, intermediate-, and low-risk groups with 5-year survival rates of 58.2, 80.6, and 100 %, respectively. Although there were no differences in treatment performed during the castration-resistant stage, patients undergoing alternative anti-androgen and zoledronic acid treatment had better PCaSS after being castration-resistant. CONCLUSIONS As PSA could not be a prognostic factor in PCa patients with high PSA > 100 ng/mL, the novel risk classification using M stage and GS may help clinicians to predict PCaSS and to plan follow-up schedules after diagnosis.
