Dural Metastases

Prostate cancer with extensive dural metastases is very rare, with only few cases described in the literature. We report one such case of a 74-year-old man with advanced prostate cancer, and in relatively good clinical condition. The patient returned with complaints of headache and diplopia. Fluorocholine (18F) chloride (18F-FCH) is an analog of choline in which a hydrogen atom has been replaced by fluorine (18F). After crossing the cell membrane by a carrier-mediated mechanism, choline is phosphorylated by choline kinase to produce phosphorylcholine. 18F-FCH positron emission tomography–computed tomography (PET/CT) is widely used to stage and restage patients affected by prostate cancer with good sensitivity. 18F-FCH PET/CT showed disease progression with the onset of multiple skull lesions. Numerous suspicious dural hypermetabolic lesions indicating neoplastic involvement were detected along the fronto-parietal convexities, in the left fronto-orbital region and right lateral wall of the orbit, concerning for metastases in these regions. A contrast-enhanced computed tomography (CECT) scan was performed which showed corresponding enhancing tissue which correlated with the PET findings. The final imaging diagnosis was osteo-dural metastases from prostate cancer associated with poor outcome. Awareness of this pattern of metastases may be of clinical relevance in order to avoid unnecessary invasive diagnostic procedures in groups of patients with a dismal prognosis.

Background: to explore the diagnostic accuracy of 18F-Fluciclovine positron-emission tomography (PET) in prostate cancer (PCa), considering both primary staging prior to radical therapy, biochemical recurrence, and advanced setting. Methods: A systematic web search through Embase and Medline was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Studies performed from 2011 to 2020 were evaluated. The terms used were “PET” or “positron emission tomography” or “positron emission tomography/computed tomography” or “PET/CT” or “positron emission tomography-computed tomography” or “PET-CT” and “Fluciclovine” or “FACBC” and “prostatic neoplasms” or “prostate cancer” or “prostate carcinoma”. Only studies reporting about true positive (TP), true negative (TN), false positive (FP) and false negative (FN) findings of 18F-fluciclovine PET were considered eligible. Results: Fifteen out of 283 studies, and 697 patients, were included in the final analysis. The pooled sensitivity for 18F-Fluciclovine PET/CT for diagnosis of primary PCa was 0.83 (95% CI: 0.80–0.86), the specificity of 0.77 (95% CI: 0.74–0.80). The pooled sensitivity for preoperative LN staging was 0.57 (95% CI: 0.39–0.73) and specificity of 0.99 (95% CI: 0.94–1.00). The pooled sensitivity for the overall detection of recurrence in relapsed patients was 0.68 (95% CI: 0.63–0.73), and specificity of 0.68 (95% CI: 0.60–0.75). Conclusion: This meta-analysis showed promising results in term of sensitivity and specificity for 18F-Fluciclovine PET/CT to stage the primary lesion and in the assessment of nodal metastases, and for the detection of PCa locations in the recurrent setting. However, the limited number of studies and the broad heterogeneity in the selected cohorts and in different investigation protocols are limitation affecting the strength of these results.

The purpose is to present a modern data on the possibilities of positron emission computed tomography combined with computed tomography (PET/CT) in the diagnosis, staging and monitoring of prostate cancer (PC).Material and Methods. A search and analysis of the largest domestic and English-language databases (Elibrary, PubMed, Elsevier, etc.) on this problem was carried out. 37 sources were found devoted to studying the results of clinical trials of the diagnostic capabilities of PET/CT with various radiopharmaceuticals.Results. The presented data on the possibilities of PET/CT with various radiopharmaceuticals in the diagnosis of primary prostate cancer, imaging of lymphogenous and distant metastases, as well as in assessing the effectiveness of treatment.Conclusion. This review of the literature showed that the use of PET/CT in prostate cancer largely depends on the chosen radiopharmaceutical. Moreover, it is PET/CT with PSMA-based radiopharmaceuticals that is the most promising method for examining patients with prostate cancer and can be recommended as an additional study in cases where other methods of radiation diagnostics do not give an unambiguous answer. The development of new and improving the already used radiopharmaceuticals, which will increase the sensitivity, specificity and accuracy of the diagnosis, staging, monitoring and prognosis of treatment of prostate cancer, remains relevant.

Abstract Background Biopsy is considered the gold-standard technique for prostate cancer diagnosis and is recommended in patients with a high clinical indication of prostate cancer. In this study, we aimed to determine the diagnostic efficacy of a novel positron emission tomography (PET)/computed tomography (CT)-guided percutaneous trans-pararectal space-based approach to targeted prostate biopsy.Methods PET/CT-guided percutaneous trans-pararectal space prostate biopsies were performed in 14 consecutive patients with indications of prostate cancer. Whole-body 18 F-FDG PET/CT indicated the presence of 18 F-fluorodeoxyglucose (FDG)-avid focal prostate lesions. Two tissue specimens were obtained from each patient. The final diagnoses were established based on the results of a histopathological analysis and clinical follow-up, and these findings were used to verify the diagnostic accuracy of 18 F-FDG PET/CT for prostate cancer.Results The diagnostic accuracy of 18 F-FDG PET/CT for prostate cancer was 81.8%. Further analyses of the two biopsied samples per patient led to confirmed histopathological and immunohistochemical diagnoses of prostate cancer in all 14 patients. Consequently, the success rate of PET/CT-guided percutaneous trans-pararectal space prostate-targeted biopsy for the diagnosis of prostate cancer was 100.0% (14/14). Regarding safety, the average duration of biopsy was 20 min, and no serious complications occurred.Conclusions PET/CT-guided percutaneous trans-pararectal space prostate biopsy may yield a new approach to targeted prostate biopsy for the diagnosis of prostate cancer. Moreover, this biopsy procedure can be performed safely without complications, and is more cost-effective than conventional trans-rectal and trans-perineal prostate biopsy methods.

Introduction: We sought to evaluate the diagnostic performance of 18F-fluorocholine positron emission tomography-computed tomography (18F-FCH PET/CT) for initial staging of patients with high-risk prostate cancer. Secondary objectives were to compare the value of 18F-FCH PET/CT to conventional imaging modalities and to evaluate its clinical impact. Methods: We conducted a retrospective study of 76 patients who underwent 18F-FCH PET/CT for initial staging of high-risk prostate cancer. Using pre-established validation criteria, sensitivity and specificity were determined for metastatic disease. Results were compared to findings on magnetic resonance imaging (MRI), computed tomography (CT), and bone scan (BS) when available. Results: Twenty-two (29%) PET/CT scans were positive, 49 (64%) negative, and five (7%) equivocal for nodal or metastatic disease. Of the positive scans, 17 showed regional lymph node involvement, 12 distant nodes, five bone metastases, and three lung metastases. Overall per-patient sensitivity, specificity, positive and negative predictive values for metastatic disease were 65%, 100%, 100%, and 78%, respectively. Sensitivity, specificity, and positive and negative predictive values were 64%, 100%, 100%, and 80%, respectively, for nodal involvement and 86%, 100%, 100%, and 98%, respectively, for bone and other metastases. Conventional imaging was negative for the lesion(s) found on PET/CT in five patients. PET/CT changed the clinical management in nine patients (12%). Conclusions: Although 18F-FCH PET/CT offers some benefits over conventional imaging and demonstrates a high specificity, it remains limited by its sensitivity in the context of high-risk prostate cancer staging. PET with novel urea-based small molecule prostate-specific membrane antigen (PSMA) inhibitors may overcome some of these limitations. However, the interpretation of the study result is limited by the lack of available histological gold standard, the inclusion of several patients who received androgen-deprivation therapy (ADT) prior to PET/CT, our retrospective design, and a relatively small sample size.

The Impact

Introduction: Conventional imaging (CI) performs poorly to identify sites of disease in biochemically recurrent prostate cancer. 68Ga-PSMA-11 positron emission tomography/ computed tomography (PET/CT) is most studied but has a very short half-life. This study reports the diagnostic performance of the novel prostate-specific membrane antigen (PSMA) radiotracer 18F-DCFPyL using real-life data, and tumor board simulation to estimate the impact of 18F-DCFPyL PET on patient management. Methods: Ninety-three 18F-DCFPyL PET/CT scans performed for patients previously treated for prostate cancer with a rising prostate-specific antigen (PSA) were retrospectively compared to contemporary CI, and clinical, imaging and PSA followups. A chart review was performed to document prior imaging, pathology results, serial serum PSA measurements, and other pertinent clinical data. Clinical utility of 18F-DCFPyL PET was measured using a simulated tumor board formed by three physicians with extensive prostate cancer experience deciding on management with and without knowledge of PET/CT results. Results: At median PSA 2.27 (interquartile range [IQR] 5.27], 82% of 18F-DCFPyL PET/CT demonstrated at least one site of disease: non-regional lymph nodes (37% of scans), regional lymph node metastases (28%), local recurrence (27%), bone metastases (20%), with higher PET positivity at higher PSA. Compared to 18F-DCFPyL PET/CT, CI showed overall poor performance, with accuracy below 20% for all extent of disease. PET/CT changed management in 44% of cases. The most frequent scenario was a radical change from initiating androgen deprivation therapy (ADT) to stereotactic body radiotherapy (SBRT) of oligo-lesional disease. In univariate and multivariate analysis, no patient characteristic could predict change of management by PET/CT results. Conclusions: 18F-DCFPyL significantly outperforms CI in recurring prostate cancer and is likely to impact management.
