ABSTRACT

Purpose: This is a secondary analysis examining a six-month home-based Prostate Cancer-Patient Empowerment Program (PC-PEP) on patient-reported urinary, bowel, sexual, and hormonal function in men with curative prostate cancer (PC) against standard of care. Methods: In a crossover clinical trial, 128 men scheduled for PC surgery (n = 62) or radiotherapy with/without hormones (n = 66) were randomized to PC-PEP (n = 66) or waitlist-control and received the standard of care for 6 months, and then PC-PEP to the end of the year. PC-PEP included daily emails with video instructions, aerobic and strength training, dietary guidance, stress management, and social support, with an initial PFMT nurse consultation. Over 6 months, participants in the PC-PEP received optional text alerts (up to three times daily) reminding them to follow the PFMT video program, encompassing relaxation, quick-twitch, and endurance exercises; compliance was assessed weekly. Participants completed baseline, 6, and 12-month International Prostate Symptom Score (IPSS) and Expanded Prostate Cancer Index Composite (EPIC) questionnaires. Results: At 6 months, men in the PC-PEP reported improved urinary bother (IPSS, p = 0.004), continence (EPIC, p < 0.001), and irritation/obstruction function (p = 0.008) compared to controls, with sustained urinary continence benefits at 12 months (p = 0.002). Surgery patients in the waitlist-control group had 3.5 (95% CI: 1.2, 10, p = 0.024) times and 2.3 (95% CI: 0.82, 6.7, p = 0.11) times higher odds of moderate to severe urinary problems compared to PC-PEP at 6 and 12 months, respectively. Conclusions: PC-PEP significantly improves lower urinary tract symptoms, affirming its suitability for clinical integration alongside established mental health benefits in men with curative prostate cancer.

ABSTRACT

BACKGROUND: Although survival rates for newly diagnosed prostate cancer patients are very high, most of them will likely suffer significant treatment-related side effects, depression, or anxiety, affecting their quality of life. OBJECTIVE: The aim of this study was to examine the effects of a 6-mo online home-based physical, mental, and social support intervention, the Prostate Cancer Patient Empowerment Program (PC-PEP), on preventing psychological distress among men undergoing curative prostate cancer treatment. DESIGN, SETTING, AND PARTICIPANTS: In a crossover randomized clinical trial of 128 men aged 50-82 yr scheduled for curative prostate cancer surgery or radiotherapy (± hormone treatment), 66 received the 6-mo PC-PEP intervention and 62 were randomized to a waitlist-control arm and received the standard of care for 6 mo, and then PC-PEP to the end of the year. The PC-PEP intervention consisted of daily e-mails with video instructions providing education, patient activation, and empowerment on healthy living including physical and mental health, dietary recommendations, social support, physical and pelvic floor fitness, stress reduction using a biofeedback device, social connection and intimacy, and social support. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome was nonspecific psychological distress (clinical cutoff ≥20) measured at baseline, and at 6 and 12 mo using the Kessler Psychological Distress Scale (K10). RESULTS AND LIMITATIONS: At 6 mo, patients in the waitlist-control group had 3.59 (95% confidence interval: 1.12-11.51) times higher odds for nonspecific psychological distress and need for psychological treatment than men who received the PC-PEP intervention. At 12 mo, the wait-list control group that received the intervention at 6 mo had higher psychological distress than the early group. CONCLUSIONS: PC-PEP delivered early following diagnosis significantly prevented the burden of psychological distress in men undergoing curative prostate cancer treatment compared with standard of care, or late (6 mo later) intervention. PATIENT SUMMARY: In this report, we looked at the effectiveness of a program (Prostate Cancer Patient Empowerment Program: PC-PEP) developed with patients' engagement on the mental distress of patients awaiting curative treatment for their prostate cancer. The PC-PEP program lasted for 6 mo, and it prescribed, described, and demonstrated daily aerobic and strength training, kegels (pelvic floor training to help with urinary and sexual function), dietary changes that have been shown to be helpful in the prevention of prostate cancer and prostate cancer progression, stress reduction using a biofeedback device, as well as social and emotional support. All patients in the PC-PEP program were invited to a monthly video conference with the leads of the program who appeared in the 6 mo of daily videos prescribing the activities the patients were asked to watch and follow. The leads were a prostate cancer oncologist and a scientist in prostate cancer quality of life research. Half of the patients in this study received PC-PEP daily for the first 6 mo and were re-assessed at the end of the year. The other half received standard of care for 6 month and then received the intervention to the end of the year. The results of the study show that, at 6 mo, this intervention was effective at reducing the mental distress that accompanies a prostate cancer diagnosis and treatment compared with the standard of care. Mental distress was significantly reduced when the intervention was received early, compared with that received late (6 mo after scheduled curative treatment). We conclude that multi-faceted patient education and empowerment programming of this kind that is developed with patient engagement from the start is crucial to the care of patients diagnosed with prostate cancer and should be implemented in the standard of care. While treatment for prostate cancer is highly successful, side effects that accompany most treatments significantly affect the quality of life of patients. Here, we describe PC-PEP, a patient education and activation program that is cost effective, highly enforced by patients, and successful at reducing the impact of prostate cancer active treatment-related side effects on their psychological state.

The program is now being tested in a phase 4 implementation trial throughout Canada and internationally (New Zealand), and is being expanded and tested for other types of cancer.

ABSTRACT

The management of prostate cancer (PCa) is dependent on biomarkers of biological aggression. This includes an invasive biopsy to facilitate a histopathological assessment of the tumor's grade. This review explores the technical processes of applying magnetic resonance imaging based radiomic models to the evaluation of PCa. By exploring how a deep radiomics approach further optimizes the prediction of a PCa's grade group, it will be clear how this integration of artificial intelligence mitigates existing major technological challenges faced by a traditional radiomic model: image acquisition, small data sets, image processing, labeling/segmentation, informative features, predicting molecular features and incorporating predictive models. Other potential impacts of artificial intelligence on the personalized treatment of PCa will also be discussed. The role of deep radiomics analysis-a deep texture analysis, which extracts features from convolutional neural networks layers, will be highlighted. Existing clinical work and upcoming clinical trials will be reviewed, directing investigators to pertinent future directions in the field. For future progress to result in clinical translation, the field will likely require multi-institutional collaboration in producing prospectively populated and expertly labeled imaging libraries.

ABSTRACT

The initial management of potentially oligometastatic hormone sensitive prostate cancer has been complicated by rapid advances in the field. Clinically, subgroup analyses of two randomized control trials have suggested that a specific synchronous oligometastatic prostate cancer state may be predictive for benefit from radiation to the primary. Further exploration of metastasis-directed therapy has been supported for various prostate cancer populations among three phase II clinical trials. There are numerous caveats in applying this evidence, a dilemma being addressed by present and upcoming clinical trials. Despite existing clinical equipoise and an avenue to address this uncertainty, the temptation to combine this evidence off-trial exists. Matters have become more complex as our ability to evaluate metastatic disease and tumour biology have also matured. This paper synthesizes our understanding of prostate cancer's natural history into a model which rationalizes both the theoretical benefits and limitations of metastasis directed therapy. We postulate that a metastatic prostate cancer's total disease activity is primarily driven by the combination of its burden of disease and underlying biology, namely genomic instability, then highlight the numerous remaining questions that challenge this hypothesis. This review focuses on harmonizing the language used to describe the disease, the current efforts exploring this hypothesis, and the need for clinical trial participation to appropriately advance patient care.

ABSTRACT

BACKGROUND: Novel radiomic features are enabling the extraction of biological data from routine sequences of MRI images. This study's purpose was to establish a new model, based on the joint intensity matrix (JIM), to predict the Gleason score (GS) of prostate cancer (PCa) patients. METHODS: A retrospective dataset comprised of the diagnostic imaging data of 99 PCa patients was used, extracted from The Cancer Imaging Archive's (TCIA) T2-Weighted (T2-WI) and apparent diffusion coefficient (ADC) images. Radiomic features derived from JIM and the grey level co-occurrence matrix (GLCM) were extracted from the reported tumor locations. The Kruskal-Wallis test and Spearman's rank correlation identified features related to the GS. The Random Forest classifier model was implemented to identify the best performing signature of JIM and GLCM radiomic features to predict for GS. RESULTS: Five JIM-derived features: contrast, homogeneity, difference variance, dissimilarity, and inverse difference were independent predictors of GS (p < 0.05). Combined JIM and GLCM analysis provided the best performing area-under-the-curve, with values of 78.40% for GS ≤ 6, 82.35% for GS = 3 + 4, and 64.76% for GS ≥ 4 + 3. CONCLUSION: This retrospective study produced a novel predictive model for GS by the incorporation of JIM data from standard diagnostic MRI images.

ABSTRACT

PURPOSE: To assess the prevalence and nature of incidental findings (IF) seen in low-dose computed tomographies (LDCT) from a lung cancer screening study for at-risk individuals. MATERIALS AND METHODS: Radiology reports from LDCTs of 4073 participants of a lung cancer screening study were retrospectively reviewed for findings other than lung nodules, that is, IFs, which were regarded as actionable. The frequency, nature, and expected cost of these IFs, and their anticipated follow-up were estimated. RESULTS: There were 880 IFs described in 782 study participants (19%); the median age of the participants was 62 years (range, 46-80 years). More IFs were found in men (55%) than in women. The majority of these findings were noncardiovascular (76%), for which imaging was suggested for 74%. There were 7 severe IFs (0.8%) that merited immediate attention. Seven known cancers were diagnosed from follow-ups of the IFs. The majority of IFs (n = 486 [55%]) would require imaging follow-up if clinically indicated, with an estimated total a cost of CAN$45,500 to CAN$51,000 to provide initial diagnostic workup. CONCLUSION: IFs on lung cancer screening studies are not uncommon and frequently require imaging or other follow-up for definitive diagnoses and to assess their clinical relevance. The implication of IFs has to be considered when determining a cost-effective and ethical protocol for the utilisation of LDCT in a high-risk population.
