Abstract
PURPOSE OF REVIEW Tumor-informed circulating tumor DNA (ctDNA) is an emerging biomarker in urothelial carcinoma. Recent clinical trials have investigated the integration of ctDNA into clinical decision-making in patients with muscle-invasive bladder cancer, their findings suggest that ctDNA may potentially revolutionize the way we stratify patients to different treatment modalities. RECENT FINDINGS ctDNA informed from TURBT specimens was found to be prognostic of disease outcomes among patients with localized nonmetastatic bladder cancer. Detectable precystectomy ctDNA status was associated with worse survival outcomes. Additionally, ctDNA status was predictive of adverse disease on radical cystectomy, including the likelihood of disease upstaging, lymph node involvement, and having a locally advanced disease (≥pT3a). In the postcystectomy minimal residual disease (MRD) period, ctDNA status may refine patient selection to adjuvant therapy, and if validated by ongoing clinical trials, patients with undetectable postcystectomy ctDNA status may forgo adjuvant treatment, regardless of pathological stage. On the contrary, patients with pre or postcystectomy detectable ctDNA status may benefit from treatment intensification. SUMMARY The integration of ctDNA in clinical decision-making has the potential to revolutionize the way we manage urothelial carcinoma by refining patient selection to different treatment modalities. This approach could ultimately lead to personalization of oncological care, with the potential to reduce both treatment-related and financial toxicity.

[PMID: 38105804 PMCID: PMC10724209 DOI: 10.1016/j.bas.2023.102716] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 05/08/2023] [Revised: 11/18/2023] [Accepted: 11/25/2023] [Indexed: 12/19/2023]
Abstract
Introduction Although urothelial carcinoma (UC) generally is non-invasive, contrastingly in 25% of patients UC metastasizes. Isolated central nervous system (CNS) metastasis from UC without other distant metastases are considered rare. In this report we describe a patient with an isolated and solitary cerebellar metastasis from UC. Research question In this case report we explore the value of histological analysis of CNS metastases, imaging, treatment options and survival. Material and methods A rare case is presented of a patient diagnosed with an isolated CNS metastasis originating from UC. Through a systematic review of literature route of dissemination, current imaging and treatment options, and survival are discussed. Results A 77-year-old male was diagnosed with a pT2N0M0 high-grade UC and treated with transurethral resection and chemoradiation therapy. Several months later, the patient presented with neurological symptoms, and radiological imaging revealed a solitary cerebellar mass. A body CT scan showed no other metastasis. After surgical resection, histology confirmed urothelial origin of the mass, matching his primary UC and the patient received post-operative stereotactic radiotherapy at the surgical site. Recurrence of the cerebellar mass occurred after 6 months for which the patient received re-resection. The patient died 5.5 months after re-resection. Discussion and conclusion Isolated brain metastases without other distant metastases from UC are rare, so histologic confirmation of the brain metastasis is essential, particularly when the time interval between diagnosis of the UC and brain metastasis increases. Early brain CT is not recommended. PET CT may have additional value in detection of other distant metastases from UC. Despite advancements in treatments, prognosis for CNS metastasis from UC remains poor.

Abstract
Molecular imaging with positron emission tomography is a powerful tool in bladder cancer management. In this review, we aim to address the current place of the PET imaging in bladder cancer care and offer perspectives on potential future radiopharmaceutical and technological advancements. A special focus is given to the following: the role of [18F] 2-[18F]fluoro-2-deoxy-D-glucose positron emission tomography in the clinical management of bladder cancer patients, especially for staging and follow-up; treatment guided by [18F]FDG PET/CT; the role of [18F]FDG PET/MRI, the other PET radiopharmaceuticals beyond [18F]FDG, such as [68Ga]- or [18F]-labeled fibroblast activation protein inhibitor; and the application of artificial intelligence.

Abstract
BACKGROUND Mycoplasma hominis infection is common in urinary tract. 18F-FDG-PET/CT is a valuable tool for tumor and infection diagnosis. Few studies have shown the 18F-FDG-PET/CT images after mycoplasma infection. CASE PRESENTATION Here we described a case of Waldenstrom macroglobulinemia with thickened bladder wall. The 18F-FDG-PET/CT showed the SUVmax up to 36.1 mimicking bladder cancer. The results of histopathological examination and metagenomic sequencing of the blood and urinary revealed the Mycoplasma hominis infection. CONCLUSION The full consideration should be given to the possibility of infection besides tumor in lesions with high SUV value in 18F-FDG-PET/CT, especially in immunodeficiency patients.

Abstract
Bladder cancer is a common disease in men and the elderly. Current treatment paradigms include radical resection of the bladder and lymph nodes or transurethral resection, both supported by chemotherapy and/or radiation. New modalities, such as illumination-based therapies are also being translationally pursued. However, while survival rates have increased due to combined therapies (particularly chemotherapy, radiation, immune checkpoint inhibitors, and surgery), a lack of diagnostic markers leads clinical professionals to rely on frequently invasive and expensive means of monitoring, such as magnetic resonance imaging or bladder cystoscopy. To improve real-time diagnostic capabilities, biomarkers that reflect both the metabolic and metastatic potential of tumor cells are needed. Furthermore, indicators of therapy resistance would allow for rapid changes in treatment to optimize survival outcomes. Fortunately, the presence of nanoscale extracellular vesicles in the blood, urine, and other peripheral fluids allow for proteomic, genomic, and transcriptomic analyses while limiting the invasiveness of frequent sampling. This review provides an overview of the pathogenesis and progression of bladder cancer, standard treatments and outcomes, some novel treatment studies, and the current status of biomarker and therapy development featuring exosome-based analysis and engineering.

Management of Bladder Cancer Patients with Clinical Evidence of Lymph Node Invasion (cN+). Cancers (Basel) 2022; 14:5286.

Abstract
The purpose of this review is to present the current knowledge about the diagnostic and treatment options for bladder cancer (BCa) patients with clinically positive lymph nodes (cN+). This review shows compaction of CT and MRI performance in preoperative prediction of lymph node invasion (LNI) in BCa patients, along with other diagnostic methods. Most scientific societies do not distinguish cN+ patients in their guidelines; recommendations concern muscle-invasive bladder cancer (MIBC) and differ between associations. The curative treatment that provides the best long-term survival in cN+ patients is a multimodal approach, with a combination of neoadjuvant chemotherapy (NAC) and radical cystectomy (RC) with extended pelvic lymph node dissection (ePLND). The role of adjuvant chemotherapy (AC) remains uncertain; however, emerging evidence indicates comparable outcomes to NAC. Therefore, in cN+ patients who have not received NAC, AC should be implemented. The response to ChT is a crucial prognostic factor for cN+ patients. Recent studies demonstrated the growing importance of immunotherapy, especially in ChT-ineligible patients. Moreover, immunotherapy can be suitable as adjuvant therapy in selected cases. In cN+ patients, the extended template of PLND should be utilized, with the total resected node count being less important than the template. This review is intended to draw special attention to cN+ BCa patients, as the oncological outcomes are significantly worse for this group.

Head-to-head Intra-individual Comparison of [ 68Ga]-FAPI and [ 18F]-FDG PET/CT in Patients with Bladder Cancer. Mol Imaging Biol 2022; 24:651-658. [PMID: 35349039 PMCID: PMC9296390 DOI: 10.1007/s11307-022-01715-3] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2021] [Revised: 02/15/2022] [Accepted: 02/28/2022] [Indexed: 10/28/2022]
Abstract
AIM/PURPOSE Fibroblast activation protein-(FAP)-ligands, a novel class of tracers for PET/CT imaging, demonstrated promising results in previous studies in various malignancies compared to standard [18F]FDG PET/CT. 68Ga-labeled fibroblast activation protein inhibitor-([68Ga]Ga-DOTA-FAPI)-PET/CT impresses with sharp contrasts in terms of high tumor uptake and low background noise leading to clear delineation. [18F]FDG PET/CT has limited accuracy in bladder cancer due to high background signal. Therefore, we sought to evaluate the diagnostic potential of [68Ga]FAPI in patients with bladder cancer. MATERIAL AND METHODS This retrospective analysis consisted of 8 patients (median age 66), 7 of whom underwent both [68Ga]FAPI and [18F]FDG PET/CT scans with a median time interval of 5 days (range 1-20 days). Quantification of tracer uptake was determined with SUVmax and SUVmean. Furthermore, the tumor-to-background ratio (TBR) was derived by dividing the SUVmax of tumor lesions by the SUVmax of adipose tissue, skeletal muscle, and blood pool. RESULTS Overall, 31 metastases were detected in five patients including lymph node metastases (n = 23), bone metastases (n = 4), lung metastases (n = 3), and a peritoneal metastasis (n = 1). In one patient, [68Ga]FAPI demonstrated significant uptake in the primary tumor located in the bladder wall. [68Ga]FAPI-PET/CT demonstrated significantly higher uptake compared to [18F]FDG PET/CT with higher mean SUVmax (8.2 vs. 4.6; p = 0.01). Furthermore, [68Ga]FAPI detected additional 30% (n = 9) lesions, missed by [18F]FDG. TBR demonstrated favorable uptake for [68Ga]FAPI in comparison to [18F]FDG. Significant differences were determined with regard to metastasis/blood pool ([68Ga]FAPI 5.3 vs [18F]FDG 1.9; p = 0.001). CONCLUSION [68Ga]FAPI-PET/CT is a promising diagnostic radioligand for patients with bladder cancer. This first described analysis of FAP-ligand in bladder cancer revealed superiority over [18F]FDG in a small patient cohort. Thus, this so far assumed potential has to be confirmed and extended by larger and prospective studies.

COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2022; 2022:7979523. [PMID: 35035524 PMCID: PMC8759889 DOI: 10.1155/2022/7979523] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/01/2021] [Revised: 11/01/2021] [Accepted: 11/10/2021] [Indexed: 11/18/2022]
Abstract
The research is aimed at investigating computed tomography (CT) image based on deep learning algorithm and the application value of ceramide glycosylation in diagnosing bladder cancer. The images of ordinary CT detection were improved. In this study, 60 bladder cancer patients were selected and performed with ordinary CT detection, and the detection results were processed by CT based on deep learning algorithms and compared with pathological diagnosis. In addition, Western Blot technology was used to detect the expression of glucose ceramide synthase (GCS) in the cell membrane of tumor tissues and normal tissues of bladder. The comparison results found that, in simple CT clinical staging, the coincidence rates of T1 stage, T2a stage, T2b stage, T3 stage, and T4 stage were 28.56%, 62.51%, 78.94%, 84.61%, and 74.99%, respectively; and the total coincidence rate of CT clinical staging was 63.32%, which was greatly different from the clinical staging of pathological diagnosis (P < 0.05). In the clinical staging of algorithm-based CT test results, the coincidence rates of T1 stage and T2a stage were 50.01% and 91.65%, respectively; and those of T2b stage, T3 stage, and T4 stage were 100.00%; and the total coincidence rate was 96.69%, which was not obviously different from the clinical staging of pathological diagnosis (P > 0.05). Therefore, it could be concluded that the algorithm-based CT detection results were more accurate, and the use of CT scans based on deep learning algorithms in the preoperative staging and clinical treatment of bladder cancer showed reliable guiding significance and clinical value. In addition, it was found that the expression level of GCS in normal bladder tissues was much lower than that in bladder cancer tissues. This indicated that the changes in GCS were closely related to the development and prognosis of bladder cancer. Therefore, it was believed that GCS may be an effective target for the treatment of bladder cancer in the future, and further research was needed for specific conditions.

Abstract
In the urinary tract, bladder cancer is the most common malignancy. It is a heterogenous cancer type with approximately 30% presenting as muscle invasive bladder cancer with a high risk of metastatic spread associated with risk of death from distant metastases. The other 70% of bladder cancer patients present with superficial tumors with tendency of recurrence but in general not life-threatening. Like in other malignancies, accurate and precise staging of bladder cancer is one of the mainstays at the time of diagnosis to select the optimal treatment for each patient. The detection of metastatic spread is of utmost importance for selection of treatment strategy. Hybrid imaging med with FDG PET/CT is widely used in the clinical management of a variety of malignancies. FDG PET/CT is increasingly used for primary staging of muscle invasive bladder cancer and for detection of recurrence after radical cystectomy. Few studies have used FDG PET/CT for response evaluation of neoadjuvant, induction chemotherapy or immunotherapy. Furthermore, small studies have tested non-FDG PET agents with little or no urinary excretions of the tracer. This review provides an update on PET/CT in bladder cancer.
