To describe the full range of symptom exacerbations defined by people with interstitial cystitis/bladder pain syndrome and chronic prostatitis/chronic pelvic pain syndrome as 'flares', and to investigate their associated healthcare utilization and bother at two sites of the Multidisciplinary Approach to the Study of Chronic Pelvic Pain (MAPP) Epidemiology and Phenotyping study. ⋯ Our findings suggest that flares are common and associated with greater symptoms, healthcare utilization, disruption and bother. Our findings also show the characteristics of flares most bothersome to patients (i.e. increased pelvic pain and duration), and thus of greatest importance to consider in future research on flare prevention and treatment.

To determine whether the pretreatment neutrophil-to-lymphocyte ratio (NLR), a measure of systemic inflammatory response, is associated with overall survival (OS) in men receiving chemotherapy with docetaxel for metastatic castration-resistant prostate cancer (mCRPC). ⋯ Men who were treated with first-line docetaxel for mCRPC who had a low pretreatment NLR (≤3.0) had significantly longer OS. NLR may be a potentially useful clinical marker of systemic inflammatory response in predicting OS in men with mCRPC who receive docetaxel and may be helpful to stratify patients for clinical trials. These findings derived from a retrospective analysis need to be validated in larger populations in prospective studies, and in the context of different therapies.

To investigate the post-prostatectomy and long-term outcomes of men presenting with an elevated pretreatment prostate-specific antigen (PSA) level (>10 ng/mL), but otherwise low-risk features (biopsy Gleason score ≤6 and clinical stage ≤T2a). ⋯ Men with PSA >20 ng/mL or men with PSA >10 and ≤20 ng/mL with a PSAD ≥0.15 ng/mL/g, but otherwise low-risk PCa, are at greater risk of adverse pathological and oncological outcomes and may be inappropriate candidates for active surveillance. These men are at greater risk of having anterior tumours that are undersampled at biopsy, so if treatment is deferred, ancillary testing such as anterior zone sampling or magnetic resonance imaging should be strongly encouraged. Men with elevated PSA levels >10 and ≤20 ng/mL but low PSAD have outcomes similar to those in the low-risk group, and consideration of surveillance is appropriate in these cases.

To compare the diagnostic accuracy of the following imaging techniques in the detection of spine metastases, using magnetic resonance imaging (MRI) as a reference: whole-body bone scintigraphy (WBS) with technetium-99m-MDP, [18F]-sodium fluoride (NaF) positron emission tomography (PET)/computed tomography (CT) and [(18) F]-fluoromethylcholine (FCH) PET/CT. ⋯ We found that FCH-PET/CT and NaF-PET/CT were superior to WBS with regard to detection of prostate cancer bone metastases within the spine. The present results call into question the use of WBS as the method of choice in patients with hormone-naïve prostate cancer.

To outline the development of the 'Timing of Androgen Deprivation' (TOAD) protocol, a collaborative randomised clinical trial under the auspices of the Cancer Council Victoria, the Trans-Tasman Radiation Oncology Group, and the Urological Society of Australia and New Zealand (USANZ), which opened to recruitment in 2004. ⋯ The question of timing of ADT remains relevant in the current era of newer and more varied treatment methods. Even with the advent of novel chemotherapy and the biological agents that are undergoing investigation for progressively earlier disease stages, the dilemma of when to commence palliative treatment in an asymptomatic patient will remain, unless or until these agents are shown to increase overall survival. The TOAD trial will contribute to answering at least in part, some of these questions.
