Abstract
Introduction Intensive treatment is typically considered for very high-risk patients with locally advanced prostate cancer and an expected survival time of 5 years or longer. Herein, we report a case of locally advanced prostate cancer with rectal infiltration treated with laparoscopic total pelvic exenteration combined with transanal total mesorectal excision. Case presentation A 73-year-old man presented with a ring-shaped mass around the rectum. He was diagnosed with prostate cancer with rectal infiltration and underwent laparoscopic total pelvic exenteration combined with transanal total mesorectal excision following neoadjuvant androgen deprivation therapy. Twenty-two months postoperatively during ongoing androgen deprivation therapy, no biochemical recurrence was observed. Conclusion To our knowledge, this is the first report of a laparoscopic total pelvic exenteration combined with transanal total mesorectal excision for prostate cancer with rectal infiltration. We believe this surgery may be considered a new option for high-risk prostate cancer patients with rectal infiltration.

Abstract
Prostate adenocarcinomas with metastatic cranial involvement are rare, with signs and symptoms overlapping with those of the primary base of the skull tumour. The diagnosis was made following a biopsy of the suspected lesions that indicated the possibility of a prostatic primary malignancy based on immunohistochemistry using prostate-specific membrane antigen and subsequently confirmed histologically. We report an unusual case of a 52-year-old male who presented with unilateral proptosis and no prior urological history. Cranial, pulmonary, and thoracolumbar spinal metastases were identified with radiological imaging. We describe the diagnostic evaluation and treatment, as well as outline the rare nature of this case of cranial metastasis of prostate cancer.

Abstract
Prostate-specific membrane antigen (PSMA) PET/CT is being increasingly utilized as a hybrid imaging modality for the evaluation of prostate cancer (PCa). We report a case of a 50-year-old man with biopsy-proven high-risk PCa in which multiple tracer avid perirenal fascia deposits were identified on 68Ga-PSMA-11 PET/CT, in addition to multi-focal prostatic primary, extensive nodal, and skeletal metastases. This case highlights that perirenal fascia is an uncommon metastatic site in PCa.

Abstract
ABSTRACT Lymph nodes, bones, and liver are the most typical metastatic sites for prostate cancer. However, isolated liver metastasis from prostate cancer is extremely rare. Here, we report a 75-year-old man with newly diagnosed prostate adenocarcinoma, with isolated liver metastasis detected by 68 Ga-PSMA ( 68 Ga-prostate-specific membrane antigen) PET/CT. There was no sign of regional or distant metastases elsewhere. This case highlights the value of 68 Ga-PSMA PET/CT in detecting a very uncommon solitary liver metastasis from prostate cancer.

Abstract
Lung-only metastatic prostate cancer can be seen in 4.6% of patients and historically patients with visceral metastastic disease are considered high risk. In order to determine survival outcomes in this patient population, we conducted a restrospective review of patients with metastatic hormone sensitive prostate cancer with lung-only metastases. In this single institution review, 10 patients were identified with 8 achieving a complete response and 2 achieving a partial response when treated with androgen deprevation therapy (ADT) with or without metastastetomy. The median progression free survival was 64.4 months with 8 of these patients (80%) with ongoing complete response at time of follow-up. Lung-only metastases may serve as a good prognostic characteristic which will allow the clinician to treat with ADT alone with or without surgery to minimize treatment realted toxicity and still offer the ability to achieve a complete response with prolonged survival.

Abstract
A 75-year-old male patient with suspicious cervical lymph nodes in level IV on the left side is presented. The cervical mass was detected in PSMA-PET-MRI as part of a restaging examination conducted due to an increase of PSA levels in the context of the patient's known prostate cancer. We conducted a selective cervical level IV lymphadenectomy with the aid of a gamma probe subsequent to radiolabelling with 99mTc-PSMA. Two visibly enlarged lymph nodes with high gamma probe signals could be extracted. Histopathological examination revealed lymph node metastases of the known prostate cancer. Using an adequate tracer radio-guided surgery helps to detect pathological lymph nodes in the head and neck region allowing for supraselective resection.

Abstract
BACKGROUND Prostate cancer (PC) is mainly known to metastasize to bone, lung and liver, but isolated metastases of prostate cancer, including ductal carcinoma, in the urinary tract are very rare. We describe two patients with nodular masses in the urinary tract (the anterior urethra or the urinary bladder) that were found on cystoscopy during treatment of castration-resistant prostate cancer. CASE PRESENTATION In both cases, the pathological diagnosis from transurethral tumor resection showed that they were androgen indifferent prostate cancer (AIPC), including aggressive variant prostate cancer (AVPC) in Case 1 and treatment-induced neuroendocrine differentiation prostate cancer (NEPC) in Case 2. In Case 1, Loss of genetic heterozygosity (LOH) of BRCA2 and gene amplification of KRAS was identified from the urethra polyps. In Case 2, homozygous deletion was observed in PTEN, and LOH without mutation was observed in RB1. CONCLUSION These are the first reports of two cases of urinary tract metastasis of AIPC.

Abstract
Disseminated tumor cells (DTCs) spread systemically yet distinct patterns of metastasis indicate a range of tissue susceptibility to metastatic colonization. Distinctions between permissive and suppressive tissues are still being elucidated at cellular and molecular levels. Although there is a growing appreciation for the role of the microenvironment in regulating metastatic success, we have a limited understanding of how diverse tissues regulate DTC dormancy, the state of reversible quiescence and subsequent awakening thought to contribute to delayed relapse. Several themes of microenvironmental regulation of dormancy are beginning to emerge, including vascular association, co-option of pre-existing niches, metabolic adaptation, and immune evasion, with tissue-specific nuances. Conversely, DTC awakening is often associated with injury or inflammation-induced activation of the stroma, promoting a proliferative environment with DTCs following suit. We review what is known about tissue-specific regulation of tumor dormancy on a tissue-by-tissue basis, profiling major metastatic organs including the bone, lung, brain, liver, and lymph node. An aerial view of the barriers to metastatic growth may reveal common targets and dependencies to inform the therapeutic prevention of relapse.

Abstract
Introduction Isolated lung metastases from prostate cancer without any other organ involvement are rare. They are commonly in the form of diffuse or multiple lesions and rarely emerge as a solitary pulmonary nodule. Presentation of case A 61-year-old man who had undergone a laparoscopic-assisted radical prostatectomy for prostate cancer 16 months prior presented with a growing solitary pulmonary nodule. Positron emission tomography/computed tomography showed an abnormal uptake in the nodule without any other organ involvement. A surgical specimen by a thoracoscopic wedge resection proved a diagnosis of a metastasis from prostate cancer. He is currently alive only with worsening pulmonary metastases at 7 years after the lung surgery. Discussion A rare entity of isolated pulmonary metastases could be a sole finding of metastatic prostate cancer over the years and its initial manifestation could emerge as a solitary pulmonary nodule. It poses a diagnostic challenge because primary lung cancer is the leading differential diagnosis of solitary pulmonary nodules and is also one of the most frequent second primary malignancies in prostate cancer survivors. Conclusion An aggressive surgical biopsy is essential for definitive histopathological and immunohistochemical analyses of solitary pulmonary nodules to distinguish a rare form of an isolated pulmonary relapse from a second primary lung cancer in prostate cancer survivors. Isolated pulmonary metastasis without bone involvement from prostate cancer may rarely emerge as a solitary pulmonary nodule. Primary lung cancer is a leading differential diagnosis of solitary pulmonary nodules in general and is also one of the most frequent second primary malignancies in prostate cancer survivors. A surgical lung biopsy is a feasible option for a definitive histoimmunological diagnosis of solitary pulmonary nodules to distinguish a rare form of an isolated pulmonary metastasis from a second primary lung cancer in prostate cancer survivors.

Abstract
Parenchymal brain metastases from prostate cancer are unusual and are associated with poor prognosis. Given the rarity of this entity, little is known about its molecular and histologic characteristics. Here we describe a patient with metastatic castration-resistant, mismatch repair-deficient (dMMR) prostate cancer with parenchymal brain metastases. Analysis of a brain metastasis revealed MLH1 loss consistent with dMMR, yet few tumor-infiltrating lymphocytes (TILs). He was treated with immune checkpoint blockade (ICB) and exhibited an extra-central nervous system (CNS) systemic response but CNS progression. Subsequent assessment of a brain metastasis following ICB treatment surprisingly showed increased TIL density and depletion of macrophages, suggestive of an enhanced antitumor immune response. Post-treatment tumoral DNA sequencing did not reveal acquired mutations that might confer resistance to ICB. This is the first description of ICB therapy for a patient with prostate cancer with parenchymal brain metastases, with pre- and post-treatment immunogenomic analyses.

Abstract
Objectives: Prostate cancer metastasizing to the brain is remarkably uncommon, with the incidence never having been described in the modern setting. The objective of this study was to determine the incidence and imaging pattern of intracranial metastasis from prostate cancer in a large cohort of Australian men with prostate cancer. Material and Methods: Retrospective review was undertaken of imaging reports for all known prostate cancer patients, who underwent an imaging examination inclusive of the brain, between July 1, 2014, and July 1, 2020. Once an intracranial lesion was identified, all available imaging and clinical notes were reviewed. Results: A total of 5644 imaging examinations which included the brain were identified in 4341 prostate cancer patients. The majority (92.1%) of examinations were 68-Gallium-labeled prostate-specific membrane antigen (68Ga-PSMA) positron emission tomography/computed tomography (PET/CT). Eight patients were identified as having an intracranial metastasis from prostate cancer, yielding an incidence of 0.18%. All patients had a Gleason score of 9 (where known), and the majority of patients (5/8) had a non-acinar variant of prostate cancer. At the time of diagnosis of intracranial metastasis, all patients had extensive metastatic disease. Imaging characteristics of the intracranial lesions were highly variable. Conclusion: The incidence of intracranial metastasis in prostate cancer patients has never been well-established. In this study, we determined the incidence as being 0.18%. Given the majority of metastasis constituted unexpected findings on routine restaging 68Ga-PSMA PET/CT, the incidence determined in our study is arguably the most accurate and clinically relevant described to date.

Abstract
Pulmonary oligo-metastases and oligo-recurrences are terms used to define a set of clinical conditions consisting of limited metastatic malignant disease characterized by an intermediate aggressive behavior compared to diffuse metastatic conditions. If the primary tumor has been controlled and extra-thoracic lesions are excluded, there is a suggestion in the medical literature that removal of such lesions could potentially prolong survival. The lungs are a common metastatic spreading site, especially from epithelial malignancies and sarcomas; pulmonary surgical or interventional metastasectomy have been proposed with curative intent in case of limited tumor load (usually less than 5 lesions). There are many series reporting data about colorectal, renal or breast lung metastasectomy, but the absence of multi centric prospective trials determines a lack of definitive evidence, especially for less common tumors such as metastatic germ cell and prostate cancer. They rarely present in the oligo-metastatic form and their management is often based on personal experience. The aim of our article is to review the latest evidence in the treatment of pulmonary metastatic germ cell and prostate tumors. We cover the full range of treatments: from surgery to ablative radiotherapy and combination of local and systemic therapy. Despite the absence of evidence based guidelines, it emerges that pulmonary metastasectomy should always be considered when general criteria for resection have been met. In germ cell tumors surgery should be mainly reserved for residual disease after chemotherapy, whereas in prostate cancer, pulmonary metastasectomy should be preferred to avoid or delay hormonal deprivation therapy and its side effects.

Case Rep Oncol 2021; 14:284-289.

Abstract
An 83-year-old man with core needle biopsy-proven Gleason score 5 prostate cancer had received radiotherapy including 18 Gy brachytherapy to the prostate cancer, leading to no locoregional and distant recurrence for more than 5 years with the normalization of elevated prostate-specific antigen (PSA) level before the radiotherapy. Due to the enlargement of coexisting ground glass nodule (GGN) in the left lung from 1 to 2.1 cm, the patient underwent wide resection of the GGN 7 years later. Under the diagnosis of adenocarcinoma in situ of the lung, follow-up computed tomography 6 months after the wide resection showed a rapid enlargement of a solid nodule having been judged as a presumed inflammatory nodule in the middle lobe, highly suggesting a malignant neoplasm of the lung. Due to both the tall columnar atypical cells with trabecular pattern on frozen section and no elevation of serum PSA level, we judged the nodule as a primary adenocarcinoma of the lung and further resected the middle lobe with lymph node dissection. Immunostaining of the tumor showed all the CK7, CK20, TTF-1, napsin A, synaptophysin, chromogranin, CD56, CDX2, p53, beta-catenin, and MUC2 negative, and PSA highly positive, clearly showing the solid nodule as a solitary lung metastasis of the prostate cancer. Physicians should note the possible solitary lung metastasis of prostate cancer, especially bearing indolent biology, with no elevation of the PSA level even after the completion of standard 5-year follow-up.

Abstract
A 74-year-old man with prostate adenocarcinoma (Gleason 7) was referred for Ga-prostate-specific membrane antigen (PSMA-HBED-CC) PET/CT scan for staging. Findings confirmed the prostate malignancy and demonstrated a solitary metastasis in the left skull base, with no evidence of regional or distant metastasis elsewhere. Solitary base of the skull metastasis may be subtle and easily overlooked, highlighting the need for thorough evaluation of the region.

Abstract
INTRODUCTION Metastatic prostatic adenocarcinoma (PAC) has mostly involved the pelvic lymph nodes; metastases to the cervical lymph nodes are exceedingly rare. MATERIALS AND METHODS A retrospective review of cytopathology files (January 1990 to March 2019) identified 13 cases of metastatic PAC to cervical lymph nodes diagnosed using fine-needle aspiration biopsy (FNAB). The clinical and demographic information were collected from the electronic medical records, and the slides were reviewed. RESULTS A total of 13 male patients with a mean age at FNAB 69 years (range, 61-86 years); 12 patients had a known history of PAC. In the patient without a history of PAC, the FNAB finding had been misinterpreted as papillary thyroid carcinoma. The interval between the original diagnosis and cervical lymph node metastasis was 98.5 months (range, 1-288 months). Most involved the left side (85%). Most smears had a clean background with few lymphocytes (46%) and numerous cellular clusters in flat sheets and acini (62%) and were composed of polygonal cells (46%) with round-oval shaped nuclei and indistinct cell borders (92%). The cytoplasm was granular (61%) or scanty (46%). The nuclei were uniform, size ≥2 times that of a neutrophil (69%). Prominent nucleoli and anisonucleosis were seen in 54% of cases; cellular pleomorphism was infrequent (30%). Immunostains confirmed the prostate origin in 7 tissue cores. CONCLUSIONS Metastatic PAC to the cervical lymph nodes occurs infrequently. If the history is unknown, cases can be misdiagnosed as metastases from cervical neoplasms. The findings indicating metastatic PAC to the cervical lymph nodes on FNAB include involvement of left-sided cervical lymph nodes in elderly male patients and cellular smears composed of uniform polygonal cells, arranged in flat sheets and acini, with granular cytoplasm, indistinct cell borders, and round-oval nuclei with prominent nucleoli.

Abstract
Cancer is the second leading cause of death worldwide, with prostate cancer, the second most commonly diagnosed cancer among men. Prostate cancer develops in the peripheral zone of the prostate gland, and the initial progression largely depends on androgens, the male reproductive hormone that regulates the growth and development of the prostate gland and testis. The currently available treatments for androgen dependent prostate cancer are, however, effective for a limited period, where the patients show disease relapse, and develop androgen-independent prostate cancer (AIPC). Studies have shown various intricate cellular processes such as, deregulation in multiple biochemical and signaling pathways, intra-tumoral androgen synthesis; AR over-expression and mutations and AR activation via alternative growth pathways are involved in progression of AIPC. The currently approved treatment strategies target a single cellular protein or pathway, where the cells slowly develop resistance and adapt to proliferate via other cellular pathways over a period of time. Therefore, an increased research aims to understand the efficacy of combination therapy, which targets multiple interlinked pathways responsible for acquisition of resistance and survival. The combination therapy is also shown to enhance efficacy as well as reduce toxicity of the drugs. Thus, the present review focuses on the signaling pathways involved in the progression of AIPC, comprising a heterogeneous population of cells and the advantages of combination therapy. Several clinical and pre-clinical studies on a variety of combination treatments have shown beneficial outcomes, yet further research is needed to understand the potential of combination therapy and its diverse strategies.

Abstract
Bone marrow stroma influences metastatic prostate cancer (PCa) progression, latency, and recurrence. At sites of PCa bone metastasis, cancer-associated fibroblasts and tumor-associated macrophages interact to establish a perlecan-rich desmoplastic stroma. As a heparan sulfate proteoglycan, perlecan (HSPG2) stores and stabilizes growth factors, including heparin-binding Wnt3A, a positive regulator of PCa cell growth. Because PCa cells alone do not induce CAF production of perlecan in the desmoplastic stroma, we sought to discover the sources of perlecan and its growth factor-releasing modifiers SULF1, SULF2, and heparanase in PCa cells and xenografts, bone marrow fibroblasts, and macrophages. SULF1, produced primarily by bone marrow fibroblasts, was the main glycosaminoglycanase present, a finding validated with primary tissue specimens of PCa metastases with desmoplastic bone stroma. Expression of both HSPG2 and SULF1 was concentrated in αSMA-rich stroma near PCa tumor nests, where infiltrating pro-tumor TAMs also were present. To decipher SULF1's role in the reactive bone stroma, we created a bone marrow biomimetic hydrogel incorporating perlecan, PCa cells, macrophages, and fibroblastic bone marrow stromal cells. Finding that M2-like macrophages increased levels of SULF1 and HSPG2 produced by fibroblasts, we examined SULF1 function in Wnt3A-mediated PCa tumoroid growth in tricultures. Comparing control or SULF1 knockout fibroblastic cells, we showed that SULF1 reduces Wnt3A-driven growth, cellularity, and cluster number of PCa cells in our 3D model. We conclude that SULF1 can suppress Wnt3A-driven growth signals in the desmoplastic stroma of PCa bone metastases, and SULF1 loss favors PCa progression, even in the presence of pro-tumorigenic TAMs.

Resveratrol Suppresses Prostate Cancer Epithelial Cell Scatter/Invasion by Targeting Inhibition of Hepatocyte Growth Factor (HGF) Secretion by Prostate Stromal Cells and Upregulation of E-cadherin by Prostate Cancer Epithelial Cells. Int J Mol Sci 2020; 21:ijms21051760.

Abstract
Cancer mortality is primarily attributed to metastasis and the resulting compromise of organs secondary to the initial tumor site. Metastasis is a multi-step process in which the tumor cells must first acquire a migratory phenotype and invade through the surrounding tissue for spread to distant organs in the body. The ability of malignant cells to migrate and breach surrounding tissue/matrix barriers is among the most daunting challenges to disease management for men in the United States diagnosed with prostate cancer (CaP), especially since, at diagnosis, a high proportion of patients already have occult or clinically-detectable metastasis. The interaction between hepatocyte growth factor (HGF) secreted by the stroma, with its receptor c-Met located in the epithelium, must occur for epithelial CaP cells to become migratory. We studied the effects of grape-derived phytochemical resveratrol on the transition of epithelial tumor cells from sedentary to a mobile, penetrant phenotype. A time lapse microscopy assay was used to monitor the acquisition of the migratory phenotype by resveratrol. The results show that resveratrol inhibits HGF-mediated interaction between the stroma and epithelium and suppresses epithelial CaP cell migration by attenuating the control of epithelial-to-mesenchymal transition (EMT).

Abstract
Pulmonary involvement has been reported in >40% of autopsy series in patients with metastatic prostate cancer; however, isolated lung metastases have been documented in <1% of cases and 43.5% (10/23) cases underwent surgical resection and most of them have good outcome. We present a 74-year-old male Gleason high-grade prostate cancer patient with initially negative PSA and isolated pulmonary lesion which was confirmed as lung metastasis by resection. This patient received first-line endocrine therapy with leuprolide and bicalutamide endocrine and had a long-term disease-free follow-up of 3 years. The present patient had isolated lung metastasis with negative PSA, which was very rare in literature. Unexpected long-term disease-free survival was achieved after first-line endocrine therapy in this case with Gleason score of 8 metastatic prostate cancer. Whether or not the path of metastasis in this case was via lymph node jumping (negative lymph node dissection) or hematogenous (usually multiple, in bilateral lungs and lower lung fields) requires further investigation.

Abstract
Prostate-specific membrane antigen (PSMA) is a glycosylated type-II transmembrane protein highly expressed in certain tumor cells. It has emerged as a novel radiotracer for evaluation of prostate cancer. Increased PSMA expression in isolated liver lesion is a diagnostic challenge. Solitary liver metastasis from prostate cancer is rare. On the other hand, PSMA avid primary hepatocellular carcinoma (HCC) has been reported in literature. We report a case of PSMA expressing atypical HCC with normal alphafeto protein (AFP) and raised prostate specific antigen (PSA).

Abstract
Prostate cancer is the most common non-cutaneous malignancy diagnosed in men. It usually metastasizes to bone as osteoblastic lesions on radiographs and regional lymph nodes, and uncommonly to lung, liver and brain. Metastatic prostate cancer recurrence after definitive local therapy can occur in any tissue. The role of fine needle aspiration cytology (FNAC) for diagnosis of metastatic malignancies is well established in literature. We describe a 74 years old male, previously treated for localized prostate cancer, admitted to our Department after total body computed tomography revealed multiple irregular lung lesions some of which had an excavated appearance.

Abstract
BACKGROUND Accumulation of myeloid-derived suppressor cells (MDSCs) to tumors is related to cancer prognosis. We investigated the contribution of host stromal microsomal prostaglandin E synthase-1 (mPGES-1) to the accumulation of MDSCs in metastasized lungs of prostate cancer in mice. MATERIAL AND METHODS Eight-week-old male C57Bl/6 wild type (WT) mice and mPGES-1 knock out mice (mPGES-1KO) were injected with RM9 murine prostate cancer cell line (5 × 106 cells/mL). Lung metastasis was evaluated by the number of colonies, the weight of the lung, and the number of MDSCs (CD11b+Gr1+ cells) in the lung. RESULTS Intravenous injections of RM9, a murine prostate cancer cell line to WT mice revealed that lung metastasis and accumulation of MDCSs were suppressed with treatments with a Gr1 antibody, a COX-2 inhibitor, and an mPGES-1 inhibitor. Lung metastasis and accumulation of CD11b+Gr1+MDSCs were suppressed in mPGES-1KO mice. The mRNA level of stromal cell-derived factor-1 (SDF-1) in the lung and the number of accumulated SDF-1-expressing CD11b+Gr1+ MDSCs were elevated at an early stage in lung metastasis of C-X-C chemokine receptor type 4 (CXCR4)-expressing RM9 in an mPGES-1-dependent manner. The number of CXCR4-expressing CD11b+Gr1+MDSCs in WT mice was higher than that in mPGES-1KO mice. RM9 lung metastasis and accumulation of CD11b+Gr1+MDSCs were suppressed by CXCR4 antibody in WT mice but not in mPGES-1KO. WT mice transplanted with mPGES-1 KO bone marrow (BM) showed a significant reduction in lung metastasis and accumulation of CD11b+Gr1+MDSCs. CONCLUSION These results suggest that mPGES-1 enhances tumor metastasis by inducing accumulation of BM-derived MDSCs. Selective mPGES-1 inhibitors might, therefore, represent valuable therapeutic tools for the suppression of tumor metastasis.

Abstract
BACKGROUND Isolated pulmonary involvement is uncommon in metastatic hormone-sensitive prostate cancer (mHSPC). To characterize outcomes and molecular alterations of this unique patient subset, we conducted a retrospective review of patients with hormone-naïve prostate cancer presenting with lung-only metastases. METHODS This was a retrospective single-institution study. Medical records of 25 patients presenting with pulmonary-only metastases before receiving androgen deprivation therapy (ADT) were analyzed. Germline and/or somatic genomic results, where available (n = 16), were documented. Tumor tissue was analyzed using clinical-grade next-generation DNA sequencing assays. Clinical endpoints included complete prostate-specific antigen (PSA) response to ADT (<0.1 ng/mL), median overall survival (OS) from time of ADT initiation, median PSA progression-free survival (PSA-PFS), and failure-free survival (FFS) at 4 years. RESULTS Baseline characteristics were notable for 48% of men (12 of 25) having first or second-degree relatives with prostate cancer, compared with 20% expected. Complete PSA responses to ADT were noted in 52% of men, with a median PSA-PFS of 66 months, a 4-year FFS rate of 72%, and a median OS that was not reached after 190 months. In evaluable patients, molecular drivers were enriched for mismatch repair mutations (4 of 16, 25%) and homologous-recombination deficiency mutations (4 of 16, 25%). These results are limited by the small sample size and retrospective nature of this analysis. CONCLUSIONS This exploratory study represents one of the largest cohorts of lung-only mHSPC patients to-date. The prevalence of actionable DNA-repair gene alterations was higher than anticipated (any DNA-repair mutation: 8 of 16, 50%). Compared to historical data, these patients appear to have exceptional and durable responses to first-line ADT. This study suggests that pulmonary-tropic mHSPC biology may be fundamentally different from nonpulmonary mHSPC.

Cancer Imaging 2019; 19:37. [PMID: 31186052 PMCID: PMC6560719 DOI: 10.1186/s40644-019-0220-x] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2019] [Accepted: 05/26/2019] [Indexed: 12/12/2022] Open
Abstract
Background The purpose of this study was to evaluate the imaging properties of hepatic metastases in 68Ga-PSMA positron emission tomography (PET) in patients with prostate cancer (PC). Methods 68Ga-PSMA-PET/CT scans of PC patients available in our database were evaluated retrospectively for liver metastases. Metastases were identified using 68Ga-PSMA-PET, CT, MRI and follow-up scans. Different parameters including, maximum standardized uptake values (SUVmax) of the healthy liver and liver metastases were assessed by two- and three-dimensional regions of interest (2D/3D ROI). Results One hundred three liver metastases in 18 of 739 PC patients were identified. In total, 80 PSMA-positive (77.7%) and 23 PSMA-negative (22.3%) metastases were identified. The mean SUVmax of PSMA-positive liver metastases was significantly higher than that of the normal liver tissue in both 2D and 3D ROI (p ≤ 0.05). The mean SUVmax of PSMA-positive metastases was 9.84 ± 4.94 in 2D ROI and 10.27 ± 5.28 in 3D ROI; the mean SUVmax of PSMA-negative metastases was 3.25 ± 1.81 in 2D ROI and 3.40 ± 1.78 in 3D ROI, and significantly lower than that of the normal liver tissue (p ≤ 0.05). A significant (p ≤ 0.05) correlation between SUVmax in PSMA-positive liver metastases and both size (ρSpearman = 0.57) of metastases and PSA serum level (ρSpearman = 0.60) was found. Conclusions In 68Ga-PSMA-PET, the majority of liver metastases highly overexpress PSMA and is therefore directly detectable. For the analysis of PET images, it has to be taken into account that also a significant portion of metastases can only be detected indirectly, as these metastases are PSMA-negative.

Abstract
Prostate cancer is one of the most common cancers affecting men worldwide with a high recurrence rate following therapy. F-fluciclovine, is a US Food and Drug Administration-approved radiopharmaceutical for PET imaging in biochemically recurrent prostate cancer. It targets increased amino acid transporters in the cell membrane of cancer cells. We report a case of incidentally detected hepatocellular carcinoma showing F-fluciclovine uptake in a 71-year-old man with biochemically recurrent prostate cancer.

Abstract
OBJECTIVE Metastases from prostate cancer to the brain are very unusual and very few case series have been reported in the literature. Present study was performed to assess the proportion of brain metastasis from prostate cancer among other brain metastasis in men, to evaluate the distribution, pattern and magnetic resonance imaging (MRI) appearance of these metastatic lesions, and prognosis of brain metastasis in patients with prostate cancer. MATERIAL AND METHODS Between January 2010 and November 2016, 339 males who had received radiotherapy at our department were retrospectively reviewed. After the first evaluation of patients data, we reviewed only the patients with brain metastases from prostate cancer. We evaluated MRI characteristics of metastatic brain lesions and characteristics of the patients, tumor and treatment modalities. RESULTS Ten of 339 patients (2.9%) had brain metastases from prostate cancer. Sixty percent of the patients had pure intraparenchymal metastasis, 20% of the patients had pure extensive dural metastasis and 20% of them had both. Seventy-five percent of the patients with intraparenchymal metastasis had multiple metastatic lesions. The median prostate specific antigen (PSA) level was 49.40 ng/mL and the Gleason score was ≥7 in all patients. Sixty percent of the patients had distant metastasis at the time of the diagnosis of prostate cancer. Median survival time in patients with brain metastasis was 4.5 months. CONCLUSION Lesions of brain metastasis from prostate cancer had a large variety of imaging presentation and it is very difficult to distinguish them from the other brain metastasis originating from other types of cancer. Presence of a disseminated disease, high PSA level and high Gleason score can be useful parameters for the prediction of brain metastasis from prostate cancer.

Abstract
Adrenal cortical insufficiency secondary to destruction of the cortex by a metastatic tumor is a rare condition. Addison's disease is usually caused by an autoimmune process or by a tuberculous infection. We report a case of adrenal Insufficiency as the first clinical manifestation of a metastatic prostate carcinoma that occurred simultaneously with an active pulmonary infection by M. tuberculosis.

Abstract
Treatment advances lead to survival benefits of patients with advanced prostate cancer. These treatments are highly efficacious in a subset of patients; however, similarly to other cancers, after initial responses the tumors develop resistance (acquired resistance) and the patients succumb to the disease. Furthermore, there is a subset of patients who do not respond to the treatment at all (de novo resistance). Preclinical testing using patient-derived xenografts (PDXs) has led to successful drug development, and PDXs will continue to provide valuable resources to generate clinically relevant data with translational potential. PDXs demonstrate tumor heterogeneity observed in patients, preserve tumor-microenvironment architecture, and provide clinically relevant treatment responses. In view of the evolving biology of the advanced prostate cancer associated with new treatments, PDXs representing these new tumor phenotypes are urgently needed for the study of treatment responses and resistance. In this chapter, we describe methodologies used to establish prostate cancer PDXs and use of these PDXs to study de novo and acquired resistance.

Abstract
The omentum is a rare metastatic site for prostatic adenocarcinoma. We present a case of metastatic castrate-resistant prostate cancer, with progressive omentum invasive prostate cancer identified on prostate-specific membrane antigen (PSMA) PET/CT scan. Omental biopsy revealed metastatic prostate adenocarcinoma, and cabazitaxel chemotherapy was instituted with a prostate-specific antigen biochemical response. Repeat PSMA PET/CT imaging revealed increased avidity in omental metastasis. Despite prostate-specific antigen response, PSMA PET/CT did not correlate with a therapeutic response.

Abstract
Historically, a solitary pulmonary metastasis of prostate cancer was considered as metastatic or disseminated disease and could only be treated systemically. However, some patients may benefit from surgical metastasectomy of a solitary pulmonary metastasis. We present an uncommon case of resection of a solitary pulmonary metastasis of prostate cancer after previous radical prostatectomy, resulting in un-detectable prostate specific antigen.

Abstract
Cerebral metastasis secondary to prostatic adenocarcinoma is rare and it is usually a late complication in patients with widespread distant metastases. Here, we report two unusual cases of such a rare condition. Our first case presented with a large frontal contrast-enhancing lesion-associated calcification and a large tumor cyst as shown on computed tomography and magnetic resonance imaging. This is the fifth reported case of prostatic metastasis manifesting as a cystic intraparenchymal tumor in the literature. The second case presented with a large soft tissue mass in the scalp and this lesion appeared to invade through the skull and into the middle cranial fossa. He was not known to have prostate cancer before his initial presentation and it was only diagnosed following histology results of the scalp lesion.

Bone metastases from prostate cancer are very common. They are usually located on the axial skeleton. However, cranial bone metastases especially to the parietal bone are rare. We report a case of metastatic prostate cancer presenting with left parietal bone metastasis in a patient with no urological symptoms or signs. We should consider prostate cancer in any man above 60 years presenting unusual bone lesions.

Abstract
Dural prostate metastases (DPM) are a rare manifestation of metastatic prostate cancer seen in approximately one to six percent of cases. Presenting symptoms may include signs of elevated intracranial pressure, headache, altered mental status, or cranial nerve palsies. Hearing loss, sensory changes, dysarthria, and dysphagia are rare symptoms in DPM that were present in our patient. We present a case of a 58-year-old male with a known diagnosis of adenocarcinoma of the prostate presenting with symptoms of acute exacerbation of chronic obstructive pulmonary disease (COPD), sub-acute right-sided hearing loss, and right-sided facial paralysis. Over the course of hospitalization, his neurological symptoms worsened and he developed dysarthria, dysphagia, facial numbness, and worsening back pain. He also appeared more withdrawn and lethargic. The symptoms prompted a neurological evaluation and a magnetic resonance imaging (MRI) revealed multiple areas of bone marrow signal abnormality compatible with osseous metastatic disease. There was extensive smooth dural thickening as well as focal nodular thickening, both consistent with dural metastases. The patient was treated with corticosteroids and external beam radiation therapy (EBRT) with improvement in his back pain and facial paralysis. He died two weeks after completing EBRT. Although rare, DPM should be suspected in males over 50 years of age presenting with neurological symptoms. An MRI with gadolinium is most helpful in delineating the presence and extent of dural and calvarial involvement. Corticosteroids and EBRT have been shown to improve neurological function in up to 67% of patients. However, median survival post-radiation remains approximately three months.

Abstract
Generalized lymphadenopathy is a rare manifestation of carcinoma prostate. Here, we report a case of a 73-year-old male who presented with left supraclavicular lymphadenopathy along with hoarseness of voice and weight loss. His CT neck, chest, abdomen, and subsequently18F-FDG PET CT were suggestive of generalized lymphadenopathy with skeletal involvement. He was not having any urinary or bone symptoms. The biopsy of supraclavicular lymph node revealed metastatic adenocarcinoma, whose prostatic origin was suggested by IHC staining of PSA. The diagnosis was confirmed by prostatic biopsy along with markedly raised serum PSA. We emphasize that in men with adenocarcinoma of undetermined origin, a suspicion of prostate cancer is important for accurate diagnosis and therapeutic approach.

Abstract
Worldwide, prostate cancer is considered the second most common cancer in men. Most common sites for metastatic disease are lymph nodes and bones. However, isolated liver metastasis from prostate cancer is rare. We present a 75 year-old male with prostate adenocarcinoma diagnosed 7 years ago. With rising PSA, he underwent imaging and found to have isolated hepatic metastasis. After left hepatic lobectomy, his PSA dramatically decreased to < 0.01. Physicians should be aware of isolated hepatic metastasis in patients with prostate cancer. Metastasectomy should be considered in such case, and combined medical and surgical approach may prolong the overall survival.

Abstract
Soft tissue metastases of prostate cancer to other sites are extremely rare, and, to our best knowledge, there have been no reports of metastasis to soft tissue of the hand. A 63-year-old man was diagnosed with prostatic cancer. During treatment, bone and soft tissue metastases to the right hand, appearing in the first web space, were observed. The tumor was resected, along with both the first and second metacarpal bones. The thumb was reconstructed by pollicization of the remaining index finger, enabling the patient to use the pollicized thumb for activities of daily living. This is the first case report of prostate cancer metastasizing to the soft tissue in hand. After wide resection, pollicization was able to reconstruct a functional hand and thumb.

Abstract
Left-sided cervical lymphadenopathy as first presentation of metastatic prostate carcinoma is not a novel observation. Here, we discuss a case of metastatic prostate primary carcinoma with an initial presentation of a right supraclavicular mass with extension into the anterior chest wall, which on radiological investigation was suggestive of a sarcomatous tumour; however, was confirmed to be pervasive metastatic prostatic adenocarcinoma. This is the second case in literature, which reports a prostatic primary cancer presenting as a right-sided supraclavicular and anterior chest wall mass.

Abstract
Metastatic prostate cancer recurrence after definitive local therapy can occur in any tissue. Usually, the first affected site is the bone. Lung metastases without bone or lymph node involvement are extremely rare in patients with prostate cancer, and only a handful of cases are reported in the literature. In several other malignancies, such as breast cancer, sarcomas, colorectal cancer, and renal cell carcinoma, long-term disease-free survival has been reported after resection of solitary pulmonary metastases. We present three unusual cases of isolated pulmonary recurrence of prostate cancer after initial definitive local therapy. One of the patients underwent resection of the lung metastasis, resulting in a long-term disease-free survival. Both surgical excision of solitary and oligometastatic lung secondary lesions and systemic therapy can play an important role in long-term disease control. Surgery should be considered for selected and well-informed patients with pulmonary metastasis after primary localised treatment for prostate cancer.

Abstract
Fewer than 2% of patients with metastatic prostate cancer (pca) develop brain metastases. Autopsy series have confirmed the rarity of brain metastases. When present, brain metastases occur in end stage, once the pca is castrate-resistant and spread to other sites is extensive. Here, we present a rare case of a patient with pca who developed a solitary parenchymal brain metastasis as first site of relapse 9 years after radical therapy. The patient underwent craniotomy and excision of the tumour. A second recurrence was also isolated to the brain. In the literature, pca patients with brain metastases have a poor mean survival of 1-7.6 months. The patient in our case report experienced a relatively favourable outcome, surviving 19 months after his initial brain relapse.

Abstract
Although most malignant lymphadenopathy in the neck represent lymphomas or metastases from head and neck primary tumors, occasionally, metastatic disease from remote, usually infraclavicular, sites presents as cervical lymphadenopathy with or without an obvious primary tumor. In general, these tumors metastasize to supraclavicular lymph nodes, but occasionally may present at an isolated higher neck level. A search for the primary tumor includes information gained by histology, immunohistochemistry, and evaluation of molecular markers that may be unique to the primary tumor site. In addition, 18F-fluoro-2-deoxyglocose positron emission tomography combined with CT (FDG-PET/CT) has greatly improved the ability to detect the location of an unknown primary tumor, particularly when in a remote location. Although cervical metastatic disease from a remote primary site is often incurable, there are situations in which meaningful survival can be achieved with appropriate local treatment. Management is quite complex and requires a truly multidisciplinary approach. © 2015 Wiley Periodicals, Inc. Head Neck 38: E2374-E2385, 2016.
