Magnetic resonance localization of gold markers for radiotherapy is critical for the treatment planning of prostatic cancer. This study sought to enhance the visualization of gold markers by applying the three-dimensional gradient echo (3D GRE) T2* sequence and comparing it with CT scan.

29 Patients who underwent both a 3D GRE T2* sequence and a CT were evaluated by an oncologist and radiologist. The SNR, CNR and prostate volume were calculated.

The depiction of gold markers using 3D GRE T2* exhibited an enhanced quality in comparison to CT (p < 0·05). Prostate SNR, fat SNR, muscle SNR and Osteon SNR were found to be elevated in 3D GRE T2*, as opposed to the CT (p < 0·05). The comparison of the average prostate volume revealed a significant difference between the mean measurements (sig = 0, p < 0·05). The prostate Volume in 3D GRE T2* 29·03% smaller in magnitude when compared to the CT, thus bringing it into closer alignment with its authentic dimensions.

The comparison between the MRI and the CT demonstrated that 3D GRE T2* is an exceptional tool for visualizing gold markers in the realm of prostate cancer radiotherapy planning. It has the potential to minimize collateral damage to healthy cells while enhancing the precision of cancer cell targeting.

In the UK, the number of patients urgently referred for suspected cancer is increasing, and providers are struggling to cope with demand. We explore the potential cost-effectiveness of a new risk prediction test – the PinPoint test – to triage and prioritize patients urgently referred with suspected urological cancers.

Two simulation models were developed to reflect the diagnostic pathways for patients with (i) suspected prostate cancer, and (ii) bladder or kidney cancer, comparing the PinPoint test to current practice. An early economic analysis was conducted from a UK National Health Service (NHS) perspective. The primary outcomes were the percentage of individuals seen within 2 weeks and health care costs. An exploratory analysis was conducted to understand the potential impact of the Pinpoint test on quality-adjusted life years gained.

Across both models and applications, the PinPoint test led to more individuals with urological cancer being seen within 2 weeks. Using PinPoint only to prioritize patients led to increased costs overall, whereas using PinPoint to both triage and prioritize patients led to cost savings. The estimated impact on life years gained/lost was very small and highly uncertain.

Using the PinPoint test to prioritize urgent referrals meant that more individuals with urological cancer were seen within 2 weeks, but at additional cost to the NHS. If used as a triage and prioritization tool, the PinPoint test shortens wait times for referred individuals and is cost saving. More data on the impact of short-term delays to diagnosis on health-related quality of life is needed.

Low-dose-rate brachytherapy (LDR brachytherapy) with Iodine-125-seeds is an established treatment modality for low- and favourable intermediate-risk prostate cancer. Our single institution experience in this field was retrospectively studied.

Two-hundred sixty consecutive patient records were reviewed for demographic, disease, therapy and side effect data. The patients were divided into subgroups by pre- and post-implant prostate-specific antigen (PSA) levels and by different LDR brachytherapy techniques used, that is, preoperative planning technique (PPT) versus intraoperative real-time planning (IOR). Data were analysed by Kaplan–Meier method and appropriate testing was conducted for PSA biochemical recurrence (BCR) and for toxicities.

After median follow-up of 65·0 months, 94·0% of all patients were free from BCR. This endpoint showed no significant differences by patient age, initial PSA, PSA decrease over time, Gleason score and implanted total activity. Patients with IOR were free of BCR in 98·9% (180/182) versus 76·9% (40/52) with PPT. All patients with a PSA nadir of <0·1 ng/mL were free from BCR. Six patients (2·5%) reported an incontinence grade 1. Transient nocturia/urge and dysuria appeared in 54·7% and 22·6% of patients.

Consistent with literature, LDR brachytherapy for low- and intermediate-risk prostate cancer appeared highly effective for freedom from BCR with mild side effects.

To identify early symptoms and changes in QoL among men with primary localized prostate cancer (PC) who later develop metastases.

From an ongoing prospective study of 3.885 men with localized PC, primarily treated with radiotherapy (RT), a subsample of men developing metastatic PC (mPC) following the first year after the start of RT and that had died during the follow-up (mPC group, n = 107) were matched against men who did not develop metastases (non-mPC group, n = 214). Data were collected using the EORTC QLQ-C30 and PCSS instruments. Non-parametric tests were performed for comparisons at baseline, end of RT, 3 months, and 1, 2, 3, and 5 years after RT.

The final sample consists of 317 men (mPC n = 106; non-mPC n = 211) who had completed at least one questionnaire. Initially, symptom levels were generally low and QoL and functioning high in both groups. An increasing difference between the groups was found, where the mPC group gradually deteriorated from the 2-year follow-up. Significant differences were found for several outcomes at 3 and 5 years. In a sensitivity analysis, where metastatic patients were removed from the time-point of verified metastases, most differences did not remain significant. Significant deterioration over time was seen within both groups for some outcomes.

The results indicate that unmet supportive needs occur over time among these men. Worsening QoL or functioning and symptoms may be difficult to recognize when the development is gradual over several years, and with various access to systematic follow-up in late phases. This highlights the need for continuous monitoring of PC patients to detect needs for supportive interventions early and throughout the disease course, also among those with non-metastatic disease who have undergone curatively intended treatment.

High-risk prostate cancer is the most common presentation at our institute among patients with non-metastatic prostate cancer. Traditionally, pelvic lymph nodes were given a prophylactic dose of radiotherapy while the prostate was given a curative dose of radiation. This study aims to evaluate patterns of failure in patients who had prostate-only radiation at our centre.

All high-risk prostate cancer patients who underwent radical radiotherapy to prostate only since 2014 were retrospectively analysed. Local T stage, baseline prostate-specific antigen (PSA) and Gleason score were recorded. Bone scan and staging CT scan data were collected. Various dose levels prescribed to prostate were analysed. The follow-up records of these patients were assessed. Patients who failed in pelvic lymph nodes were recorded separately. Overall survival and failure-free survival were calculated using Kaplan–Meier curve.

One-hundred five patients fulfilling the inclusion criteria were analysed. Only three patients developed recurrence in pelvic lymph node following prostate-only radiotherapy (PORT). Five year overall survival was 77% while failure-free survival was 64%. Forty patients had a PSA failure after a median follow-up of 62 months.

Most high-risk prostate cancer patients who progress following hormone therapy and PORT have metastases outside pelvis. Till further conclusive evidence is available PORT can be considered as a safe option.

This critical review of the literature seeks to understand the psychological impact that treatment interventions may have on prostate cancer (PC) survivors.

A literature search was conducted using databases of peer-reviewed literature. The search terms used were devised using the building-blocks technique to divide the query into facets. The articles were manually assessed for relevance and appraised using the relevant Critical Appraisal Skills Programme (CASP) tool. Government guidelines and regulations were also used following a manual search on the National Institute for Health and Care Excellence (NICE) website. This process resulted in a total of 12 sources being included in the critical review.

The key themes that arose from the review were masculinity, depression, anxiety and psychological implications related to sexual functioning. Psychological impact varies on an individual basis and is influenced by the quality of a patient’s experience during and after treatment in relation to sufficient information giving and support.

Open communication should be encouraged by healthcare professionals to assess patient mental wellbeing. The extent of psychological impact varies on an individual basis; however, there are predictive factors that can make an individual more at risk of being affected psychologically post-PC treatment.

In radiation therapy, accurate dose distribution in target volume requires accurate treatment setup. The set-up errors are unwanted and inherent in the treatment process. By achieving these errors, a set-up margin (SM) of clinical target volume (CTV) to planning target volume (PTV) can be determined. In the current study, systematic and random set-up errors that occurred during prostate cancer radiotherapy were measured by an electronic portal imaging device (EPID). The obtained values were used to propose the optimum CTV-to-PTV margin in prostate cancer radiotherapy.

A total of 21 patients with prostate cancer treated with external beam radiation therapy (EBRT) participated in this study. A total of 280 portal images were acquired during 12 months. Gross, population systematic (Σ) and random (σ) errors were obtained based on the portal images in Anterior–Posterior (AP), Medio-Lateral (ML) and Superior–Inferior (SI) directions. The SM of CTV to PTV were then calculated and compared by using the formulas presented by the International Commission on Radiation Units and Measurements (ICRU) 62, Stroom and Heijmen and Van Herk et al.

The findings showed that the population systematic errors during prostate cancer radiotherapy in AP, ML and SI directions were 1·40, 1·95 and 1·94 mm, respectively. The population random errors in AP, ML and SI directions were 2·09, 1·85 and 2·29 mm, respectively. The SM of CTV to PTV calculated in accordance with the formula of ICRU 62 in AP, ML and SI directions were 2·51, 2·68 and 3·00 mm, respectively. And according to Stroom and Heijmen, formula were 4·23, 5·19 and 5·48 mm, respectively. And Van Herk et al. formula were 4·96, 6·17 and 6·45 mm, respectively.

The SM of CTV to PTV in all directions, based on the formulas of ICRU 62, Stroom and Heijmen and van Herk et al., were equal to 2·73, 4·98 and 5·86 mm, respectively; these values were obtained by averaging the margins in all directions.

To compare the acute radiation-induced bowel and bladder toxicities of two hypofractionated radiotherapy (HFRT) regimens in localised prostate cancer (PCa).

This trial consists of patients with histologically confirmed stage T1-T3aN0M0 PCa, a prostate-specific antigen concentration of 40 ng/mL or lower, and Eastern Cooperative Oncology Group performance status of 0–2. Participants were randomly assigned (1:1) to 56 Gy in 16 fractions over 4 weeks (arm A) or 70·2 Gy in 26 fractions over 5 weeks (arm B). Acute bowel and bladder toxicities were assessed using Radiation Therapy Oncology Group criteria.

Between June 2018 and December 2019, 40 patients were randomly assigned to treatment with 4-week (n = 20) and 5-week HFRT (n = 20). In the third month after completion of radiotherapy, the cumulative incidence of acute bowel and bladder toxicities of arms A and B was 20 versus 5% and 70 versus 85%, respectively. The cumulative incidence of grade 2 or worse bowel and bladder toxicities of the 5-week regimen was non-inferior to 4-week HFRT [bowel toxicity: 5% (arm A) versus 5% (arm B), bladder toxicity: 50% (arm A) versus 60% (arm B), p = 0·52).

The 5-week regimen of HFRT is non-inferior to 4-week HFRT in terms of acute bowel and bladder toxicities.

Prostate cancer is the most commonly diagnosed cancer in men and it is responsible for about 10% of all cancer mortalities in both American and Canadian men. At present, serum prostate-specific antigen levels remain the most commonly used test to detect prostate cancer, and the standard and definitive diagnosis of the disease is via prostate biopsy. Conventional tissue biopsies are usually invasive, expensive, painful, time-consuming, and unsuitable for screening and need to be consistently evaluated by expert pathologists and have limited repeatability. Consequently, liquid biopsies are emerging as a favourable alternative to conventional tissue biopsies, providing a non-invasive and cost-effective approach for screening, diagnosis, treatment and monitoring of prostate cancer patients.

We searched several databases from August to December 2020 for relevant studies published in English between 2000 and 2020 and reporting on liquid-based biomarkers available in detectable quantities in patient bodily fluid samples. In this narrative review paper, we describe seven novel and promising liquid-based biomarkers that potentially account for individual patient variability as well as used in disease risk assessment, screening for early disease detection and diagnosis, identification of patients’ risk for metastatic disease and subsequent relapse, monitoring patient response to specific treatment and providing clinicians the potential to stratify patients likely to benefit from a particular treatment.

The concept of precision medicine from prevention to treatment techniques that take individual patient variability into account will depend on the development of effective clinical biomarkers that interrogate key aberrant pathways potentially targetable with molecular targets or immunologic therapies. Liquid-based biomarkers with high sensitivity and specificity for prostate cancer are emerging as minimally invasive, lower risk, readily obtainable and easily repeatable technique for screening for early disease detection and diagnosis, patient stratification at diagnosis into different risk categories, identification of patients’ risk for metastatic disease and subsequent relapse, and real-time monitoring of patient response to specific treatment. Thus, effective liquid-based biomarkers will potentially shift the treatment paradigm of prostate cancer towards more personalised and targeted medicine.

Prostate cancer is the most commonly diagnosed cancer in men and responsible for about 10% of all cancer mortality in both Canadian and American men. Currently, serum PSA level is the most commonly used test for the detection of prostate cancer, though the levels can also be elevated in benign conditions, has limited specificity and has a high rate of overdiagnosis and treatment of indolent disease. Consequently, in recent years, several investigations have been conducted to identify novel cancer biomarkers capable of both effective screening and diagnosis, as well as assisting to shift the diagnostic and treatment paradigm of prostate cancer towards more patient-specific and targeted medicine. The goal of this narrative review paper is to describe eleven novel and promising tissue-based biomarkers for prostate cancer capable to account for individual patient variabilities and have the potential for risk assessment, early detection and diagnosis, identification of patients who will benefit from a particular treatment and monitoring patient response to treatment.

We searched several databases from August to December 2020 for relevant studies published in English between 2000 and 2020 and reporting on tissue-based biomarkers for screening and early diagnosis, treatment and monitoring of prostate cancer.

Emerging prostate cancer biomarkers have the potential to guide clinical decision-making since they have the potential to detect the disease early, measure the risk of developing the disease and the risk of progression, provide accurate information of patient response to a specific treatment and are capable of informing clinicians about the likely outcome of a cancer diagnosis independent of the treatment received. Therefore, the future holds promise for personalised and targeted medicine from prevention to diagnosis and treatment that considers the individual patient’s variabilities in the management of prostate cancer.
