Abstract
Prostate cancer (PC) has a high propensity to develop bone metastases, causing severe pain and pathological fractures that profoundly impact a patients' normal functions. Current clinical intervention is mainly palliative focused on pain management, and tumor progression is refractory to standard therapeutic regimens. This limited treatment efficacy is at least partially due to a lack of comprehensive understanding of the molecular landscape of the disease pathology, along with the intensive overlapping of physiological and pathological molecular signaling. The niche is overwhelmed with diverse cell types with inter- and intra-heterogeneity, along with growth factor-enriched cells that are supportive of invading cell proliferation, providing an additional layer of complexity. This review seeks to provide molecular insights into mechanisms underlying PC bone metastasis development and progression.

Risk Factors for Medication-Related Osteonecrosis of the Jaw-A Binomial Analysis of Data of Cancer Patients from Craiova and Constanta Treated with Zoledronic Acid. J Clin Med 2023; 12:jcm12113747. [PMID: 37297941 DOI: 10.3390/jcm12113747] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2023] [Revised: 05/26/2023] [Accepted: 05/26/2023] [Indexed: 06/12/2023] Open
Abstract
MRONJ (Medication-Related Osteonecrosis of the Jaw) is a condition observed in a subset of cancer patients who have undergone treatment with zoledronic acid in order to either prevent or treat bone metastases. The primary aim of this research was to establish the importance of risk factors in the development of medication-related osteonecrosis of the jaw in cancer patients receiving zoledronic acid therapy for bone metastases. The present study is an observational retrospective investigation conducted at two university centers, namely, Craiova and Constanța, and included cancer patients treated with zoledronic acid. The medical records of the patients were obtained over a four-year timeframe spanning from June 2018 to June 2022. The data analysis was carried out between January 2021 and October 2022. Patients were treated for cancer, bone metastases, and MRONJ according to the international guidelines. The research investigated a cohort of 174 cancer patients (109 females and 65 males) aged between 22 and 84 years (with a mean age 64.65 ± 10.72 years) seeking treatment at oncology clinics situated in Craiova and Constanța. The study conducted a binomial logistic regression to analyze ten predictor variables, namely, gender, age, smoking status, treatment duration, chemotherapy, radiotherapy, endocrine therapy, presence of diabetes mellitus (DM), obesity, and hypertension (HT). The results of the analysis revealed that only five of the ten predictor variables were statistically significant for MRONJ occurrence: duration of treatment (p < 0.005), chemotherapy (p = 0.007), and hypertension (p = 0.002) as risk factors, and endocrine therapy (p = 0.001) and obesity (p = 0.024) as protective factors.

Lower Fracture Rates in Patients Treated with Radium-223, Abiraterone or Enzalutamide, When Given Concurrently with Bone Health Agents: A Real-World Analysis. Clin Genitourin Cancer 2022; 20:399-403. [PMID: 35680530 DOI: 10.1016/j.clgc.2022.04.015] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2021] [Revised: 04/22/2022] [Accepted: 04/23/2022] [Indexed: 12/30/2022]
Abstract
BACKGROUND The phase 3 trial ERA223 demonstrated an increased fracture rate and no survival advantage for metastatic castration resistant prostate cancer (mCRPC) patients on Radium-223 (Ra-223) with abiraterone, leading to regulatory restrictions on combination therapy. However, less than half of trial patients received bone health agents (BHA). We reviewed electronic health record (EHR) data evaluating fracture rates for patients on BHA receiving Ra-223, androgen deprivation therapy and either abiraterone or enzalutamide. PATIENTS AND METHODS We conducted a retrospective, cohort analysis of EHR data of mCRPC patients on Ra-223 treated at a single community center by a single provider between 2010 and 2018. The primary objective was evaluating fracture rates for patients on BHA receiving Ra-223 and abiraterone. We conducted a secondary analysis for enzalutamide. RESULTS One hundred seventy-seven patients received Ra-223 concurrently with abiraterone or enzalutamide between November 2010 and August 2018. The median age was 73 at first Ra-223 dose (range 40-93). The median follow-up time from last Ra-223 dose was 30 months (range 2-106). One hundred sixty-four patients (93%) received BHAs. One hundred fifty-nine patients (89%) were on a BHA before and/or during Ra-223. Sixty-seven patients received denosumab (38%), 63 received zoledronic acid (36%), and 29 received both nonconcurrently (16%). Eleven patients (6.2%) experienced a fracture after starting Ra-223, 9 of which occurred while on prior and/or concurrent BHA. We observed a 5.7% fracture rate for mCRPC patients who received combination therapy and denosumab or zoledronic acid. CONCLUSION This real-world analysis demonstrating a low fracture rate in patients with mCRPC receiving a BHA while on Ra-223 and abiraterone or enzalutamide may inform current clinical practice.

Abstract
Osteoporosis is called a silent disease, because it is difficult to detect until comprehensive examinations for osteoporosis are performed or osteoporotic fractures occur. Zoledronic acid is currently the first-line anti-osteoporotic drug, with good efficacy and treatment compliance. A major advantage of zoledronic acid is that intravenous zoledronic acid often guarantees a therapeutic effect for up to 1 year after infusion. The reasons why zoledronic acid is effective in improving osteoporosis are that it can inhibit osteoclast differentiation and induce osteoclast apoptosis, thus suppressing bone resorption and increasing bone density. The story between zoledronic acid and osteoclasts has been written long time ago. Both the canonical receptor activator of the receptor activator of nuclear factor-κB ligand (RANKL) pathway and the non-canonical Wnt pathway are the main pathways by which zoledronic acid inhibits osteoclast differentiation. Farnesyl pyrophosphate synthase (FPPS), reactive oxygen species (ROS), and ferroptosis that was first proposed in 2012, are all considered to be closely associated with zoledronic acid-induced osteoclast apoptosis. Here, we provide a brief review of the recent progress on the study of zoledronic acid and osteoclasts, and hope to elaborate how zoledronic acid improves osteoporosis by acting on osteoclasts.

Abstract
OBJECTIVE This article reviews the effects of androgen deprivation therapy on bone health and loss of bone mineral density and its effects on risk of fractures for men with prostate cancer, as well as describes the assessment, management, and nursing strategies for patient and caregiver education, prevention strategies, and side effect management. DATA SOURCES Peer-reviewed articles formed the basis of this article. CONCLUSION Androgen deprivation therapy has a deleterious effect on bone health, causing loss of bone mineral density and increasing the risk of fractures. The significant decrease in bone mineral density and fractures in elderly men can lead to morbidity, mortality, and poor quality of life. Bone mineral density assessment prior to initiating androgen deprivation therapy should be performed to identify bone issues prior to initiating therapy and to ensure that preventive bone health management strategies are executed. IMPLICATIONS FOR NURSING PRACTICE Awareness of bone loss factors for men treated with androgen deprivation therapy is important in caring for patients undergoing treatment for prostate cancer. Bone fractures can have a significant impact on activities of daily living and diminish quality of life. Oncology nurses can play a key role in patient and caregiver education regarding the importance of bone health management strategies and the assessment of patient-related risk factors that may limit adherence to treatment recommendations.

Abstract
BACKGROUND In patients with spinal metastases, kinematic instability is postulated to be a predictor of pathologic vertebral fractures. However, the relationship between this kinematic instability and the loss of spinal strength remains unknown. METHODS Twenty-four 3-level thoracic and lumbar segments from 8 cadaver spines from female donors aged 47 to 69 years were kinematically assessed in axial compression (180 N) and axial compression with a flexion or extension moment (7.5 Nm). Two patterns of lytic defects were mechanically simulated: (1) a vertebral body defect, corresponding to Taneichi model C (n = 13); and (2) the model-C defect plus destruction of the ipsilateral pedicle and facet joint, corresponding to Taneichi model E (n = 11). The kinematic response was retested, and compression strength was measured. Two-way repeated-measures analysis of variance was used to test the effect of each model on the kinematic response of the segment. Multivariable linear regression was used to test the association between the kinematic parameters and compressive strength of the segment. RESULTS Under a flexion moment, and for both models C and E, the lesioned spines exhibited greater flexion range of motion (ROM) and axial translation than the control spines. Both models C and E caused lower extension ROM and greater axial, sagittal, and transverse translation under an extension moment compared with the control spines. Two-way repeated-measures analysis revealed that model E, compared with model C, caused significantly greater changes in extension and torsional ROM under an extension moment, and greater sagittal translation under a flexion moment. For both models C and E, greater differences in flexion ROM and sagittal translation under a flexion moment, and greater differences in extension ROM and in axial and transverse translation under an extension moment, were associated with lower compressive strength of the lesioned spines. CONCLUSIONS Critical spinal lytic defects result in kinematic abnormalities and lower the compressive strength of the spine. CLINICAL RELEVANCE This experimental study demonstrates that lytic foci degrade the kinematic stability and compressive strength of the spine. Understanding the mechanisms for this degradation will help to guide treatment decisions that address inferred instability and fracture risk in patients with metastatic spinal disease.

Abstract
Radiotherapy and surgery are curative treatment options for localized prostate cancer (PCa) with a 5-year survival rate of nearly 100%. Once PCa cells spread into distant organs, such as bone, the overall survival rate of patients drops dramatically. The metastatic cascade and organotropism of PCa cells are regulated by different cellular subtypes, organ microenvironment, and their interactions. This cross-talk leads to pre-metastatic niche formation that releases chemo-attractive factors enforcing the formation of distant metastasis. Biological characteristics of PCa metastasis impacting on metastatic sites, burden, and latency is of clinical relevance. Therefore, the implementation of modern hybrid imaging technologies into clinical routine increased the sensitivity to detect metastases at earlier stages. This enlarged the number of PCa patients diagnosed with a limited number of metastases, summarized as oligometastatic disease. These patients can be treated with androgen deprivation in combination with local-ablative radiotherapy or radiopharmaceuticals directed to metastatic sites. Unfortunately, the number of patients with disease recurrence is high due to the enormous heterogeneity within the oligometastatic patient population and the lack of available biomarkers with predictive potential for metastasis-directed radiotherapy. Another, so far unmet clinical need is the diagnosis of minimal residual disease before onset of clinical manifestation and/or early relapse after initial therapy. Here, monitoring of circulating and disseminating tumor cells in PCa patients during the course of radiotherapy may give us novel insight into how metastatic spread is influenced by radiotherapy and vice versa. In summary, this review critically compares current clinical concepts for metastatic PCa patients and discuss the implementation of recent preclinical findings improving our understanding of metastatic dissemination and radiotherapy resistance into standard of care.

Abstract
PURPOSE Radium-223 has demonstrated efficacy in improving overall survival (OS) and in delaying symptomatic skeletal-related events (SREs). Bone Health Agents (BHA), i.e. RANK ligand inhibitor (Denosumab) and bisphosphonate such as zoledronic acid, are indicated to prevent SREs without a clear survival benefit. SREs on patient health have a high impact and it is, therefore, important to consider the role of new therapies with BHA to better understand the involvement of combination therapy. The primary aim of this multicentric study is to assess OS in mCRPC patients treated with Radium-223 in combination with BHA. MATERIALS AND METHODS 430 consecutive patients treated with Radium-223 alone or in combination with BHA, affected by mCRPC, from January 2015 to July 2019 in six Italian Nuclear Medicine Units, were included. Furthermore, data were collected at baseline, after every Radium-223 administration, and during follow-up, at 3 and 6 months and 1 year after the 6th cycle. Clinical data have been evaluated before starting treatment with Radium-223 and at the end of treatment and/or at progression. Patients who received target bone therapy with BHA before Radium-223 treatment together with patients who did not receive this therapy at all (NO BHA GROUP), were compared to patients treated with concomitant Radium-223 and BHA (BHA GROUP). RESULTS In univariate models (p < .05) several clinical aspects have an impact on OS: concomitant BHA (p = .018), BMI (p .001), ECOG PS (p = .000), Baseline Hb (p = .000), Baseline PSA (p = .000), Baseline tALP (p = .000), Baseline LDH (p = .000), and Baseline neutrophils (p = .009). Baseline Hb, Baseline tALP, and Baseline LDH have been confirmed as statistically significant parameters in multivariate models. Indeed, concomitant BHA has not a significant impact on OS (p = .244) in multivariate models. CONCLUSIONS At univariate analysis, our data showed that NO BHA GROUP and BHA GROUP differ in OS by 7 months (95%CI: (1-16.4), p = .02). This is not confirmed at multivariate analysis where after adjusting for other baseline factors, BHA is not significant anymore. This is clearly explained as bias by indication: patients with the same levels of tALP, Hb, and LDH receiving or not receiving BHA are expected to have a similar survival. Our results support and confirm the role of Radium-223 therapy on OS and, furthermore, appear to confirm that BHA treatment has not a survival benefit.

Bone health effects of androgen-deprivation therapy and androgen receptor inhibitors in patients with nonmetastatic castration-resistant prostate cancer. Prostate Cancer Prostatic Dis 2020; 24:290-300. [PMID: 33028943 PMCID: PMC8134041 DOI: 10.1038/s41391-020-00296-y] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2020] [Revised: 08/24/2020] [Accepted: 09/24/2020] [Indexed: 12/19/2022]
Abstract
Background Osteoporosis is a skeletal disorder characterized by compromised bone strength, resulting in increased fracture risk. Patients with prostate cancer may have multiple risk factors contributing to bone fragility: advanced age, hypogonadism, and long-term use of androgen-deprivation therapy. Despite absence of metastatic disease, patients with nonmetastatic castrate-resistant prostate cancer receiving newer androgen receptor inhibitors can experience decreased bone mineral density. A systematic approach to bone health care has been hampered by a simplistic view that does not account for heterogeneity among prostate cancer patients or treatments they receive. This review aims to raise awareness in oncology and urology communities regarding the complexity of bone health, and to provide a framework for management strategies for patients with nonmetastatic castrate-resistant prostate cancer receiving androgen receptor inhibitor treatment. Methods We searched peer-reviewed literature on the PubMed database using key words “androgen-deprivation therapy,” “androgen receptor inhibitors,” “bone,” “bone complications,” and “nonmetastatic prostate cancer” from 2000 to present. Results We discuss how androgen inhibition affects bone health in patients with nonmetastatic castrate-resistant prostate cancer. We present data from phase 3 trials on the three approved androgen receptor inhibitors with regard to effects on bone. Finally, we present management strategies for maintenance of bone health. Conclusions In patients with nonmetastatic castrate-resistant prostate cancer, aging, and antiandrogen therapy contribute to bone fragility. Newer androgen receptor inhibitors were associated with falls or fractures in a small subset of patients. Management guidelines include regular assessment of bone density, nutritional guidance, and use of antiresorptive bone health agents when warranted.

Abstract
Bone cancer pain (BCP) is a severe complication of advanced bone cancer. Although cannabinoid receptor 2 (CB2) agonists may have an analgesic effect, the underlying mechanism remains unclear. CB2 serves a protective role in various pathological states through the activation of autophagy. Therefore, the present study aimed to determine whether the analgesic effects of the selective CB2 agonist JWH015 was mediated by the activation of autophagy in BCP. BCP was induced by the intra‑femur implantation of NCTC2472 fibrosarcoma cells in C3H/HeN mice. The pain behaviors were assessed on the following postoperative days. The selective CB2 agonist JWH015 (1 and 2 µg) was intrathecally administered on day 14 following implantation. AM630 (1 µg), a CB2 antagonist, was injected 30 min before JWH015 administration. Lipopolysaccharide (LPS; 100 nM)‑stimulated primary neurons were treated with JWH015 (1 µM) and AM630 (1 µM) to further verify the mechanism by which CB2 affects autophagy. The results demonstrated that autophagy flux was impaired in spinal neurons during BCP, as indicated by the increased ratio of microtubule‑associated protein 1 light chain 3β (LC3B)‑II/LC3B‑I and increased expression of p62. Intrathecal administration of JWH015 attenuated BCP, which was accompanied by the amelioration of impaired autophagy flux (decreased LC3B‑II/LC3B‑I ratio and decreased p62expression). In addition, the activation of glia cells and upregulation of the glia‑derived inflammatory mediators, interleukin (IL)‑1β and IL‑6 were suppressed by JWH015. In LPS‑stimulated primary neurons, IL‑1β and IL‑6 were increased, and autophagy flux was impaired; whereas treatment with JWH015 decreased the expression of IL‑1β and IL‑6, LC3B‑II/LC3B‑I ratio and expression of p62. These effects were by pretreatment with the CB2‑selective antagonist AM630. The results of the present study suggested that the impairment of autophagy flux was induced by glia‑derived inflammatory mediators in spinal neurons. Intrathecal administration of the selective CB2 agonist JWH015 ameliorated autophagy flux through the downregulation of IL‑1β and IL‑6 and attenuated BCP.

Wang Q, Sun B, Meng X, Liu C, Cong Y, Wu S. Density of bone metastatic lesions increases after radiotherapy in patients with breast cancer. JOURNAL OF RADIATION RESEARCH 2019; 60:394-400. [PMID: 30785994 PMCID: PMC6530615 DOI: 10.1093/jrr/rry098] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/27/2018] [Revised: 04/17/2018] [Indexed: 06/09/2023]
Abstract
The aim of this study was to assess local response to radiotherapy (RT) in a quantitative manner by evaluating the bone density of metastases. Spinal and pelvic bone metastases in 44 patients with breast cancer who were treated between May 2010 and December 2016 were retrospectively assessed. Bone density values of irradiated and unirradiated bone metastases before, 1-3 months after, 4-6 months after, and 7-9 months after RT were compared. At each time point, mean bone density ± standard deviation values were measured in Hounsfield units (HU) from computed tomography (CT) scans. Student's t-test was used for statistical analyses of the differences in bone density and for univariate analysis of the prognostic factors for differences in bone density at various time points after RT. Mean bone densities in irradiated and unirradiated bone metastases before RT were 297.31 ± 211.93 HU and 326.29 ± 228.61 HU, respectively. At the subsequent three time points examined, the mean bone density values in the irradiated and unirradiated bone metastases were: 61.97 ± 78.58 HU (P = 0.000) and 36.93 ± 52.49 HU (P = 0.001); 149.07 ± 133.27 HU (P = 0.000) and 68.40 ± 101.10 HU (P = 0.000); and 183.94 ± 168.30 HU (P = 0.000) and 88.21 ± 159.49 HU (P = 0.004), respectively, in each case. Patients receiving bisphosphonates exhibited greater increases in bone density in their metastases 1-3 months after RT (83.04 ± 82.18 HU vs 26.86 ± 60.55 HU, respectively; P = 0.044), whereas chemotherapy before RT was associated with significantly lower increases in bone density at the subsequent three time points [(37.53 ± 67.66 HU vs 93.63 ± 80.36 HU, P = 0.027), (99.30 ± 107.92 HU vs 180.24 ± 127.85 HU, P = 0.030), and (126.07 ± 141.77 HU vs 236.28 ± 158.22 HU, P = 0.024), respectively, in each case]. Comparing bone density values determined from CT scans appears to be a practicable and reproducible method for assessing local response to RT for bone metastasis of breast cancer. Increased bone density was also observed in the irradiated bone metastases.

Development of a glycoproteomic strategy to detect more aggressive prostate cancer using lectin-immunoassays for serum fucosylated PSA. Clin Proteomics 2019; 16:13. [PMID: 30996714 PMCID: PMC6451306 DOI: 10.1186/s12014-019-9234-4] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2018] [Accepted: 03/27/2019] [Indexed: 12/15/2022] Open
Abstract
Background Prostate-specific antigen (PSA) is commonly used as a serum biomarker for the detection of prostate cancer. However, levels of PSA in serum do not reliably distinguish aggressive prostate cancer from non-aggressive disease. Therefore, there is an urgent need for biomarkers that can differentiate aggressive prostate cancers from non-aggressive phenotypes. Fucosylation is one of the glycosylation-based protein modifications. Previously we demonstrated increased levels of serum fucosylated PSA in patients with aggressive prostate cancer using lectin selection followed by PSA immunoassay.
Methods We developed two lectin-immunoassays, Lens culinaris agglutinin (LCA) and Aleuria aurantia lectin (AAL) followed by clinical PSA immunoassay and investigated the levels of PSA and its fucosylated glycoforms in serum specimens from prostate cancer patients with different Gleason scores. First, we developed standard curves for lectins enrichment, which were applied to lectin-immunoassay for fucosylated PSA–LCA and PSA–AAL quantification in serum samples. Results Our results showed that both LCA- and AAL-immunoassays detected elevated fucosylated PSA and were correlated with higher Gleason scores but only AAL-immunoassay detected an increased percentage of fucosylated PSA in patient serum with higher Gleason scores. Conclusion We have developed quantitative lectin-immunoassays for serum fucosylated PSA. Our data demonstrated that fucosylated PSA–AAL, % fucosylated PSA–AAL and fucosylated PSA–LCA levels could be effective biomarkers to differentiate aggressive prostate cancer [especially Gleason 7 (4 + 3) or above] from non-aggressive disease. We believe that application of these lectin-immunoassays to a larger patient population is needed to evaluate the clinical utilities of fucosylated PSA using AAL–PSA and LCA–PSA for aggressive prostate cancer.
