Initial management approach for localized/locally advanced disease is critical to guide metastatic castration-resistant prostate cancer care.

Background: Currently, several therapies are available for metastatic castration-resistant prostate cancer (mCRPC) but no specific clinical factors to personalize treatment. We first sought the prognostic value of duration on androgen-deprivation therapy (ADT) for hormone-sensitive prostate cancer (HSPC) in patients receiving androgen-receptor-signaling inhibitors (ARSI) for mCRPC.

Methods: A multicenter cohort of mCRPC patients who started ARSI between July 2011 and October 2021 was identified.

Untargeted lipidomics reveal association of elevated plasma C18 ceramide levels with reduced survival in metastatic castration-resistant prostate cancer patients.

Emerging evidence highlights the potential prognostic relevance of circulating lipids in metastatic castration-resistant prostate cancer (mCRPC), with a proposed 3-lipid signature. This study aims to analyze the lipidomic profiles of individuals with mCRPC to identify lipid species that could serve as predictive indicators of prognosis and therapeutic response. Plasma samples were collected from mCRPC patients initiating first-line treatment (1 L) (n = 29) and those previously treated with at least two lines of therapy (> 2 L) (n = 19), including an androgen-receptor signaling inhibitor and a taxane.

Cardiac Metastasis from Prostate Cancer: A Case Study Underlying the Crucial Role of the PSMA PET/CT.

Prostate cancer still represents one of the most frequent cancers and causes of death worldwide, despite the huge therapeutic advances in the last decades. The introduction into clinical practice of prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA PET/CT) has significantly improved diagnostic capacity, allowing for the identification of lesions previously undetectable. The case we are presenting is about a 90-year-old man affected by metastatic prostate cancer and treated with hormonal therapies.

Clinical outcomes of volume of disease on patients receiving enzalutamide abiraterone acetate plus prednisone as first-line therapy for metastatic castration-resistant prostate cancer.

Background: Androgen receptor signaling inhibitors (ARSis) abiraterone acetate (AA) plus prednisone and enzalutamide (Enza), are currently the most administered first-line treatments for metastatic castration-resistant prostate cancer (mCRPC). AA and Enza have shown similar overall survival (OS) benefits and there is no consensus upon the best option for mCRPC first-line treatment. Volume of disease may represent a useful biomarker to predict response to therapy in such patients.

The Role of mpMRI in the Assessment of Prostate Cancer Recurrence Using the PI-RR System: Diagnostic Accuracy and Interobserver Agreement in Readers with Different Expertise.

Background: treated prostate cancer (PCa) patients develop biochemical recurrence (BCR) in 27-53% of cases; the role of MRI in this setting is still controversial. In 2021 a panel of experts proposed a "Prostate Imaging-Recurrence Reporting" (PI-RR) score, aiming to standardize the reporting. The aim of our study is to evaluate the reproducibility of the PI-RR scoring system among readers with different expertise.

Clinical impact of volume of disease and time of metastatic disease presentation on patients receiving enzalutamide or abiraterone acetate plus prednisone as first-line therapy for metastatic castration-resistant prostate cancer.

Background: Metastatic castration-resistant prostate cancer remains a challenging condition to treat. Among the available therapeutic options, the androgen receptor signaling inhibitors abiraterone acetate plus prednisone (AA) and enzalutamide (Enza), are currently the most used first-line therapies in clinical practice. However, validated clinical indicators of prognosis in this setting are still lacking.

Oligometastatic Prostate Cancer Treated with Metastasis-Directed Therapy Guided by Positron Emission Tomography: Does the Tracer Matter?

The superior diagnostic accuracy of [68Ga]Ga-prostate-specific membrane antigen-11 (PSMA) ([68Ga]Ga-PSMA-11) compared to [18F]F-Fluorocholine Positron Emission Tomography/Computed Tomography (PET/CT) in Prostate Cancer (PCa) is established. However, it is currently unclear if the added diagnostic accuracy actually translates into improved clinical outcomes in oligometastatic PCa patients treated with [68Ga]Ga-PSMA-11 PET-guided metastasis-directed therapy (MDT). The present study aimed to assess the impact of these two imaging techniques on Progression-Free Survival (PFS) in a real-world sample of oligometastatic PCa patients submitted to PET-guided MDT.

Case report: Pembrolizumab plus Axitinib related hypothyroid myopathy in two kidney cancer patients.

The first-line therapy in advanced kidney cancer has changed in recent years due to the introduction of combinations of tyrosine kinase inhibitors (TKIs) of vascular endothelial growth factor receptors (VEGFR) and immune checkpoint inhibitors (ICIs). Although immune-related adverse events are well-known, in the case of combination treatments, the determination of which drug is related to an adverse event may be challenging. We reported two cases of patients who developed muscle enzyme elevation in association with hypothyroidism during therapy with pembrolizumab plus axitinib for metastatic kidney cancer.

Beyond the Prognostic Value of 2-[F]FDG PET/CT in Prostate Cancer: A Case Series and Literature Review Focusing on the Diagnostic Value and Impact on Patient Management.

The role of 2-deoxy-2-[F]fluoro-D-glucose Positron Emission Tomography/Computed Tomography (FDG PET/CT) in the management of prostate cancer (PCa) patients is increasingly recognised. However, its clinical role is still controversial. Many published studies showed that FDG PET/CT might have a prognostic value in the metastatic castration-resistant phase of the disease, but its role in other settings of PCa and, more importantly, its impact on final clinical management remains to be further investigated.

Immune Checkpoint Inhibitors in Advanced Prostate Cancer: Current Data and Future Perspectives.

In the last 10 years, many new therapeutic options have been approved in advanced prostate cancer (PCa) patients, granting a more prolonged survival in patients with metastatic disease, which, nevertheless, remains incurable. The emphasis on immune checkpoint inhibitors (ICIs) has led to many trials in this setting, with disappointing results until now. Therefore, we discuss the immunobiology of PCa, presenting ongoing trials and the available clinical data, to understand if immunotherapy could represent a valid option in this disease, and which subset of patients may be more likely to benefit.

Opportunistic skeletal muscle metrics as prognostic tools in metastatic castration-resistant prostate cancer patients candidates to receive Radium-223.

Objective: Androgen deprivation therapy alters body composition promoting a significant loss in skeletal muscle (SM) mass through inflammation and oxidative damage. We verified whether SM anthropometric composition and metabolism are associated with unfavourable overall survival (OS) in a retrospective cohort of metastatic castration-resistant prostate cancer (mCRPC) patients submitted to 18F-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography (FDG PET/CT) imaging before receiving Radium-223.

Patients And Methods: Low-dose CT were opportunistically analysed using a cross-sectional approach to calculate SM and adipose tissue areas at the third lumbar vertebra level.

Prognostic Value of Thyroid Hormone Ratio in Patients With Advanced Metastatic Renal Cell Carcinoma: Results From the Threefour Study (Meet-URO 14).

Background: Thyroid hormone impairment, represented as an alteration in levels of thyroid hormones and a lower fT3/fT4 ratio, has been correlated with a worse prognosis for both cancer and non-cancer patients. The role of baseline thyroid function in patients with metastatic renal cell carcinoma (mRCC) however, has not been studied yet.

Materials And Methods: We recorded clinical data, baseline biochemical results, and oncological outcomes from 10 Oncology Units in Italy.

Telomerase-based GX301 cancer vaccine in patients with metastatic castration-resistant prostate cancer: a randomized phase II trial.

Debate is around the optimal immunization regimen for cancer vaccines since too intense vaccination schedules may exhaust reactive lymphocytes. GX301 is a telomerase-based cancer vaccine whose safety and immunological effects were tested in a phase I trial applying an eight administrations schedule. Main objective of this study was to comparatively analyse safety and immunological response to three GX301 regimens in metastatic castration-resistant prostate cancer patients with response/disease stability after docetaxel chemotherapy.

Combination therapy in metastatic renal cell carcinoma: Back to the future?

The treatment landscape of metastatic renal cell carcinoma (mRCC), a chemotherapy-resistant disease, has dramatically changed in the last decade after the introduction of small molecule inhibitors targeting the vascular endothelial growth factor receptor and mammalian target of rapamycin kinases. The CheckMate 025 phase III trial in second line mRCC also introduced immunotherapy with immune-checkpoint inhibitors as an option in the management of mRCC. Both small molecules and immunotherapy are used as single agents and they are associated with different toxicities.

Epidemiological Characteristics and Survival in Patients with De Novo Metastatic Prostate Cancer.

The real-world outcomes of patients with metastatic prostate cancer (mPCa) are largely unexplored. We investigated the trends in overall survival (OS) and cancer-specific survival (CSS) in patients with de novo mPCa according to distinct time periods. The U.

BRCA Mutations in Prostate Cancer: Prognostic and Predictive Implications.

Despite chemotherapy and novel androgen-receptor signalling inhibitors (ARSi) have been approved during the last decades, metastatic castration-resistant prostate cancer (mCRPC) remains a lethal disease with poor clinical outcomes. Several studies found that germline or acquired DNA damage repair (DDR) defects affect a high percentage of mCRPC patients. Among DDR defects, BRCA mutations show relevant clinical implications.

Immune Modulation in Prostate Cancer Patients Treated with Androgen Receptor (AR)-Targeted Therapy.

Androgen deprivation therapy (ADT) is a cornerstone of treatment for prostate cancer and, in recent years, androgen receptor (AR)-targeted therapies (abiraterone and enzalutamide) have both been used for the treatment of castration-resistant prostate cancer (CRPC). In our study, we sought to investigate the association between ADT and immune disorders, considering a potential role of androgens in the immune modulation. We retrospectively evaluated CRPC patients treated with abiraterone/enzalutamide between July 2011 and December 2018.

Insights from a Long-Term Follow-Up Evaluation of Early Breast Cancer Outcomes by Tumor Subtype.

Introduction: Our understanding of the granularity of breast cancer (BC) clinical outcomes by biologic subtype may be impaired by limited study follow-up times.

Objective: We evaluated the impact of modern immunohistochemistry (IHC)-based BC subtypes on long-term mortality.

Method: We used a cohort of 200 women diagnosed with stage I-III BC in the period 1985-1990.

Integrative Analysis of Periostin in Primary and Advanced Prostate Cancer.

Periostin (POSTN) is an extracellular matrix protein associated with tumor progression and shorter survival in prostate cancer (PCa). Here, we performed an integrative analysis of POSTN's role in patients with PCa. Clinical and POSTN data from large-scale datasets were analyzed.

Role of Baseline and Post-Therapy 18F-FDG PET in the Prognostic Stratification of Metastatic Castration-Resistant Prostate Cancer (mCRPC) Patients Treated with Radium-223.

Radium-223 dichloride (Ra223) represents the unique bone-directed treatment option that shows an improvement in overall survival (OS) in metastatic castrate resistant prostate cancer (mCRPC). However, there is an urgent need for the identification of reliable biomarkers to non-invasively determine its efficacy (possibly improving patients' selection or identifying responders' after therapy completion). 18F-Fluorodeoxyglucose (FDG)-avidity is low in naïve prostate cancer, but it is enhanced in advanced and chemotherapy-refractory mCRPC, providing prognostic insights.

Current Treatment Options for Metastatic Hormone-Sensitive Prostate Cancer.

The possible treatments options for metastatic hormone-sensitive prostate cancer (mHSPC) have dramatically increased during the last years. The old backbone, which androgen-deprivation therapy (ADT) is the exclusive approach for hormone-naïve patients, has been disrupted. Despite the fact that several high-quality, randomized, controlled phase 3 trials have been conducted in this setting, no direct comparison is currently available among the different strategies.

Role of Circulating Tumor Cells (CTC), Androgen Receptor Full Length (AR-FL) and Androgen Receptor Splice Variant 7 (AR-V7) in a Prospective Cohort of Castration-Resistant Metastatic Prostate Cancer Patients.

Background: Circulating tumor cells (CTC), androgen receptor full-length (AR-FL), and androgen receptor splice variant 7 (AR-V7) are prognostic in patients (pts) with metastatic castration-resistant prostate cancer (mCRPC). AR-V7 seems to predict resistance to androgen-receptor signaling inhibitors (ARSi).

Methods: We assessed the association of CTC, AR-FL, and AR-V7 with prostate-specific antigen (PSA) response and overall survival (OS).

Reduced dose of cabazitaxel in metastatic castration-resistant prostate cancer: from PROSELICA trial to the real life: A single institution experience.

The phase III PROSELICA trial showed that cabazitaxel 20 mg/m (C20) was not inferior and better tolerated compared to cabazitaxel 25 mg/m (C25) in patients with metastatic castration-resistant prostate cancer (mCRPC) who had progressed during or after docetaxel. Here, we report on a real-world retrospective analysis concerning the safety and the activity of C20 schedule in patients with mCRPC treated at our Institution. We identified 35 patients with mCRPC who received C20 as baseline dose treatment because they were frail or experienced serious toxicities to previous treatments.
