Revisiting current National Comprehensive Cancer Network (NCCN) high-risk prostate cancer stratification: a National Cancer Database analysis.

BACKGROUND: High-risk prostate cancer includes heterogenous populations with variable outcomes. This study aimed to compare the prognostic ability of individual high-risk factors, as defined by National Comprehensive Cancer Network (NCCN) risk stratification, in prostate cancer patients undergoing radical prostatectomy. METHODS: We queried the National Cancer Database from 2004 to 2018 for patients with non-metastatic high-risk prostate cancer who underwent radical prostatectomy and stratified them as Group H1: Prostate specific antigen (PSA) > 20 ng/ml alone, Group H2: cT3a stage alone and Group H3: Gleason Grade (GG) group 4/5 as per NCCN guidelines. The histopathological characteristics and rate of adjuvant therapy were compared between different groups. Inverse probability weighting (IPW)-adjusted Kaplan-Meier curves were utilized to compare overall survival (OS) in group H1 and H2 with H3. RESULTS: Overall, 61,491 high-risk prostate cancer patients were identified, and they were classified into Group H1 (n = 14,139), Group H2 (n = 2855) and Group H3 (n = 44,497). Compared to group H1 or H2, pathological GG group > 3 (p < 0.001), pathological stage pT3b or higher (p < 0.001), lymph nodal positive disease (pN1) (p < 0.001) and rate of adjuvant therapy (p < 0.001) were significantly in Group H3. IPW-adjusted Kaplan-Meier curves showed significantly better 5-year OS in group H1 compared to group H3 [95.1% vs 93.3%, p < 0.001] and group H2 compared to group H3 [94.4% vs 92.9%, p < 0.001]. CONCLUSION: PSA > 20 ng/ml or cT3a stage in isolation have better oncologic and survival outcomes compared to GG > 3 disease and sub-stratification of 'High-risk' category might lead to better patient prognostication.

Effects of yoga in men with prostate cancer on quality of life and immune response: a pilot randomized controlled trial.

BACKGROUND: Diagnosis and treatment of prostate cancer is associated with anxiety, fear, and depression in up to one-third of men. Yoga improves health-related quality of life (QoL) in patients with several types of cancer, but evidence of its efficacy in enhancing QoL is lacking in prostate cancer. METHODS: In this randomized controlled study, 29 men newly diagnosed with localized prostate cancer were randomized to yoga for 6 weeks (n = 14) or standard-of-care (n = 15) before radical prostatectomy. The primary outcome was self-reported QoL, assessed by the Expanded Prostate Index Composite (EPIC), Functional Assessment of Cancer Therapy-Prostate (FACT-P), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), Functional Assessment of Cancer Therapy-General (FACT-G) at baseline, preoperatively, and 6 weeks postoperatively. Secondary outcomes were changes in immune cell status and cytokine levels with yoga. RESULTS: The greatest benefit of yoga on QoL was seen in EPIC-sexual (mean difference, 8.5 points), FACIT-F (6.3 points), FACT-Functional wellbeing (8.6 points), FACT-physical wellbeing (5.5 points), and FACT-Social wellbeing (14.6 points). The yoga group showed increased numbers of circulating CD4+ and CD8+ T-cells, more production of interferon-gamma by natural killer cells, and increased Fc receptor III expression in natural killer cells. The yoga group also showed decreased numbers of regulatory T-cells, myeloid-derived suppressor cells, indicating antitumor activity, and reduction in inflammatory cytokine levels (granulocyte colony-stimulating factor [0.55 (0.05-1.05), p = 0.03], monocyte chemoattractant protein [0.22 (0.01-0.43), p = 0.04], and FMS-like tyrosine kinase-3 ligand [0.91 (-0.01, 1.82), p = 0.053]. CONCLUSIONS: Perioperative yoga exercise improved QoL, promoted an immune response, and attenuated inflammation in men with prostate cancer. Yoga is feasible in this setting and has benefits that require further investigation. TRIAL REGISTRATION: clinicaltrials.org (NCT02620033).

ICUD-SIU International Consultation on Bladder Cancer 2017: management of non-muscle invasive bladder cancer.

PURPOSE: To provide a summary of the Third International Consultation on Bladder Cancer recommendations for the management of non-muscle invasive bladder cancer (NMIBC). METHODS: A detailed review of the literature was performed focusing on original articles for the management of NMIBC. An international committee assessed and graded the articles based on the Oxford Centre for Evidence-based Medicine system. The entire spectrum of NMIBC was covered such as prognostic factors of recurrence and progression, risk stratification, staging, management of positive urine cytology with negative white light cystoscopy, indications of bladder and prostatic urethral biopsies, management of Ta low grade (LG) and high risk tumors (Ta high grade [HG], T1, carcinoma in situ [CIS]), impact of BCG strain and host on outcomes, management of complications of intravesical therapy, role of alternative therapies, indications for early cystectomy, surveillance strategies, and new treatments. The working group provides several recommendations on the management of NMIBC. RESULTS: Recommendations were summarized with regard to staging; management of primary and recurrent LG Ta and high risk disease, positive urine cytology with negative white light cystoscopy and prostatic urethral involvement; indications for timely cystectomy; and surveillance strategies. CONCLUSION: NMIBC remains a common and challenging malignancy to manage. Accurate staging, grading, and risk stratification are critical determinants of the management and outcomes of these patients. Current tools for risk stratification are limited but informative, and should be used in clinical practice when determining diagnosis, surveillance, and treatment of NMIBC.

Evaluation of vitamin E and selenium supplementation for the prevention of bladder cancer in SWOG coordinated SELECT.

PURPOSE: Epidemiological and biological evidence suggests a preventive effect of selenium and vitamin E on bladder cancer. We assessed the effect of selenium and/or vitamin E on bladder cancer development. MATERIALS AND METHODS: This was a secondary analysis of the randomized, placebo controlled SELECT (Selenium and Vitamin E Cancer Prevention Trial), which included 34,887 men randomly assigned to 4 groups (selenium, vitamin E, selenium plus vitamin E and placebo) in double-blind fashion between August 22, 2001 and June 24, 2004. The primary end point was bladder cancer incidence, as determined by routine clinical management. RESULTS: During a median followup of 7.1 years (IQR 6.4-8.0) 224 bladder cancer cases were recorded. Patients with bladder cancer were older, and more likely to be white and have a smoking history than those without bladder cancer. Most cancers were urothelial and nonmuscle invasive. There was no significant difference in the bladder cancer incidence between the 53 men in the placebo group and the 56 in the vitamin E group (HR 1.05, IQR 0.64-1.73, p=0.79), the 60 in the selenium group (HR 1.13, 0.70-1.84, p=0.52) or the 55 in the vitamin E plus selenium group (HR 1.05, 0.63-1.70, p=0.86). CONCLUSIONS: This secondary analysis showed no preventive effect of selenium or vitamin E alone or combined on bladder cancer in this population of men. Further studies are needed to assess the effect in women, and at different doses and formulations.
